Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a navigation device, an information center, a guidance system, and a route transmission device that perform guidance for reaching a destination.
[0002]
[Prior art]
Navigation devices that search for a travel route to a destination and guide the driver are widely used. In this navigation device, a destination is set from a telephone number, a facility name, a genre, an address, etc. (destination setting process), and a recommended travel route from the current vehicle position or departure point to the set destination is searched ( (Route search processing), while a current position is detected by a GPS receiver or the like, a route to a destination is guided by voice or image according to the searched travel route (route guidance processing).
[0003]
On the other hand, recently, the navigation device has only a minimum number of programs and data, the navigation device performs destination setting and route guidance, and the route search to the destination is performed collectively in the information center. A navigation system has also been developed. In this system, a mobile phone, a mobile phone connected to the device, a wireless communication means such as PHS (Personal Handy-phone System), etc., transmission to the destination information center, a recommended travel route searched for in the information center, etc. It is supposed to receive.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional navigation device or the like, it is necessary to operate a remote controller, a touch panel, or the like in the vehicle when setting the destination. In other words, the boarded user must turn on the power of the navigation device and set a destination number or waypoint (passage point) with a remote control, a touch panel, etc., with reference to the menu, such as a telephone number, an address, or a facility name. In other words, the destination cannot be obtained immediately after boarding, and the travel route to the destination cannot be obtained. Therefore, in a conventional navigation device or the like, it takes time to get route guidance to the destination after getting on the vehicle.
Further, even when a plurality of members travel to the same destination by their own vehicles, each member has to individually set a destination as his / her own destination or acquire a search route.
[0005]
Therefore, the present invention has an object to achieve such a problem, and a first object thereof is to make it possible to immediately acquire specific data such as a destination and a travel route by turning on the ignition.
A second object is to allow setting information such as a destination for another navigation apparatus to be set.
[0006]
By the way, the navigation device is based on the assumption that the travel route is displayed by displaying the travel route and the current position on a display device in the vehicle, or by outputting a guidance voice by a speaker in the vehicle. The destination is assumed to be reachable by the vehicle.
However, the destination that the user will finally reach is not a point that can be reached by the vehicle (vehicle destination), but means other than the vehicle such as walking or cable car (non-vehicle means) from the vehicle destination. It may be a point to reach.
For example, the final destination may not be reached without passing through a pedestrian road where vehicles cannot pass. In this case, the route from the departure point to the vehicle destination is set, but the route from the vehicle destination to the walking destination is not set. In addition, when there is no parking lot at the vehicle destination (when the vehicle destination and the walking destination are the same), and the parking lot around the destination is set as the vehicle destination, the vehicle destination and the walking destination are Different.
When moving to such a destination by walking or the like, a portable information terminal that grasps a route to a walking destination by downloading and displaying a map from the current position to the destination on a portable information terminal (PDA) It has been proposed (Japanese Patent Laid-Open No. 9-26968).
[0007]
However, in the case of such a portable information terminal, since both the current position and the destination are displayed, the destination cannot be set in advance at a place other than the departure place, and arrives at the departure place (vehicle destination). After that, it is necessary to set the final destination set before the vehicle travels again and download the map data. For this reason, after reaching the vehicle destination, it was not possible to immediately move toward the final destination.
Further, the portable information terminal needs to have a GPS receiver for detecting the position of confidence.
Furthermore, when the vehicle position is reached by traveling or the like, if the vehicle position is unknown, it is possible to set the vehicle position as a walking destination on the portable information terminal or display a map to the vehicle position. could not.
[0008]
Therefore, a third object is to make it possible to acquire the final destination or map data up to the final destination immediately after reaching the vehicle destination.
It is a fourth object of the present invention to make it possible to acquire a map and travel route data up to the vehicle position using a portable information terminal even if the vehicle position is unknown.
[0009]
In addition, in a navigation device that transmits and receives data to and from an information center, if the vehicle destination is a parking lot or the like, it is impossible to notify the information center of the current position of the vehicle or arrival at the destination by communication. There's a problem.
Therefore, a fifth object of the present invention is to make it possible to notify an information center of an arrival position or arrival using a portable information terminal even if the arrival point of the vehicle is a communication impossible point.
[0010]
[Means for Solving the Problems]

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS.
(1) Outline of the embodiment
In the present embodiment, a destination setting screen or data is received from the information center, a destination is set by a portable information terminal such as a mobile phone, and the destination is transmitted to the information center together with the user ID. The destination does not necessarily need to be a point that can be reached by a vehicle, and may be a point that cannot be reached without using a non-vehicle means such as walking or a cable car. In this way, it may be a point that cannot be reached by the vehicle (regardless of whether it is recognized or not), so when setting the destination data and screen for requesting a parking lot with the parking lot as the vehicle guidance end point When it is received and selected from the information center, a parking lot request is also transmitted to the information center. In the information center, the userConstantWhen the received destination is received, the received destination is stored in the user data corresponding to the ID as the final destination, whether there is a parking lot request, whether there is a parking lot at the final destination, the vehicle to the final destination The vehicle destination is set according to whether or not it is possible to travel and stored in user data.
[0014]
On the other hand, when the user gets into the vehicle and turns on the ignition, the in-vehicle device (navigation device) starts communication with the information center (establishment of communication) and checks whether the destination has already been set in the information center. Check.
In the information center, if the vehicle destination is set in the user data of the corresponding ID, the route search from the current position transmitted from the navigation device to the set vehicle destination is performed, and the recommended travel route is transmitted. .
As described above, since the travel route to the destination set in advance by the portable information terminal or the like can be obtained from the information center immediately after the ignition is turned on by the ignition on, the user can set the destination and set the destination from turning on the power of the navigation device. There is no need to perform a series of operations up to transmission in the vehicle. In addition, the travel route to be transmitted does not transmit the entire travel route from the departure point to the vehicle destination, but transmits only the travel route for a predetermined distance from the current position, thereby shortening the communication time (less communication data amount). The vehicle side can depart early. When the navigation device transmits a request for a travel route again when reaching a predetermined distance (for example, 200 m) before the end of the received travel route, the information center displays a travel route from the current vehicle position to the destination. A search is made again and a travel route for a predetermined distance is transmitted to the navigation device. In this way, every time there is a request, a new travel route to the destination is newly searched and transmitted by a predetermined distance, thereby transmitting an optimum travel route considering the latest traffic information at the time of the request. Can do.
[0015]
When the navigation device arrives at the vehicle destination (ends voice route guidance), the navigation device transmits the current position of the vehicle to the information center. In the information center, the travel route from the current vehicle position to the final destination is searched in the non-vehicle mode, a map picture corresponding to the travel route is created, and transmitted to the portable information terminal corresponding to the ID.
The portable information terminal provides guidance to the final destination by sequentially displaying the received map pictures according to user operations.

In FIG. 5, communication between the portable information terminal 200 and the information center 10 is represented by a dotted line, and communication between the navigation apparatus 100 and the information center 10 is represented by a one-dot chain line. Communication starts with Es, Fs, and Gs (transmission of call request packet CR in the case of packet communication, and call (off-hook) in the case of circuit switching), and communication ends with Ee, Fe, and Ge ( In the case of packet communication, a disconnection confirmation packet is received, and in the case of circuit switching, it is disconnected (on-hook).
[0041]
When the destination is pre-registered in the information center 10, the destination setting is performed in advance in the portable information terminal 200 as indicated by the arrow E0. Then, as indicated by the arrow E1, the installed destination, passing point, parking lot request, and ID of the corresponding navigation device 100 are transmitted to the information center 10. The passing point and the parking lot request are transmitted when selected in the destination setting, and are not transmitted when not selected.
As shown in FIG. 5, it is a typical case that a destination or the like is transmitted from the portable information terminal 200 to the information center 10, but in addition, the destination is set in advance by the navigation device 100 and the information center 10. When sending to a mobile phone (sending from your own device or from another navigation device), or setting a destination on an information processing terminal such as a home or office personal computer or a word processor In some cases, the destination is set and transmitted from a public telephone capable of data communication.
In the information center 10, when the destination set by the destination setting process and the ID are transmitted, the final destination and the vehicle destination are determined from the received destination as described later with reference to FIG. Register in the user data corresponding to the ID. This destination determination process is not limited to the case where the destination is set in advance, but is also executed when the destination is set by the navigation device 100 of the vehicle when the vehicle departs.
[0042]
When the vehicle equipped with the navigation device 100 is turned on, route guidance to the vehicle destination is started.
That is, as shown by the arrow F0 in FIG. 5, when the ignition of the vehicle on which the navigation device 100 is mounted is turned on, communication between the navigation device 100 and the information center 10 is established (Fs). F4 destination setting confirmation processing (FIGS. 9 and 10) is performed.
If the destination is registered in advance in the information center 10, the navigation device 100 sends the current position, ID, requested road length, and route guidance acquisition request to the information center 10 as shown by the arrow F5 (see FIG. Not shown). The requested road length is transmitted when the requested road length data 168 is stored in the data storage area 102B of the navigation device 100.
As will be described later with reference to FIG. 11, the information center 10 performs route search (vehicle mode), segment division, and requested guidance data extraction based on the received data, as indicated by an arrow F <b> 6. Then, as indicated by an arrow F7, the obtained route / guidance data is transmitted to the navigation device 100.
[0043]
The operation in the information center 10 will be described with reference to FIG.
As shown in FIG. 6, when the information center 10 receives a destination from the portable information terminal 200 or the navigation device 100, the information center 10 sets the received destination as the final destination PT and cannot reach the final destination PT by a vehicle. The vehicle destination PA is set in the case (including the case of guiding to the surrounding parking lot based on the parking lot request).
L1 indicated by a thick solid line is a travel route searched (vehicle mode) from the terminal position PD of the received divided route to the vehicle destination PA, and L2 indicated by a thick dotted line is from the vehicle destination PA to the final destination PT. This is a route that has been searched (non-vehicle mode). M is a mark indicating the vehicle position displayed corresponding to the current position of the vehicle.
The search route L1 is divided into five segments S1 to S5 when a predetermined distance (for example, 2 km) is used as a unit, and segment division points are P1 to P4. If the requested road length is LR, the transmission road length> the requested road length in the segments S1 and S2, the route data and guidance data of the segments S1 and S2 are transmitted to the navigation device 100.
[0044]
On the other hand, in the navigation device 100, as will be described later with reference to FIG. 12, as shown by an arrow F8 in FIG. 5, route guidance is performed based on the route / guidance data received in a divided manner. Note that route / guide data that is no longer needed is discarded. Here, when the route guidance continuation data is required, the current center and the route guidance acquisition request (request) are again notified to the information center 10, as indicated by the arrow F9. Thereafter, the same operation is repeated until reaching the destination. When the vehicle arrives at the vehicle destination, the current center and the arrival at the destination are notified to the information center 10 as indicated by the arrow Fn, and the navigation device 100 Communication between the information centers 10 is terminated.
[0045]
When the vehicle center arrival is received from the navigation device 100, the information center 10 stores the current position of the received vehicle as indicated by an arrow G0, and performs a route search in the non-vehicle mode from the current position to the final destination. This is performed (described later in FIG. 13). As shown by the arrow Gs, the mobile phone corresponding to the user data 50 of the corresponding IDinformationCommunication with the terminal connection destination is started, and as shown by an arrow G1, guidance data based on a map picture up to the final destination created by the route search is transmitted to the portable information terminal 200. In the portable information terminal 200 that has received the map picture, as will be described later with reference to FIGS. 14 and 15, the received map picture is displayed in sequence according to the user's operation, thereby non-vehicle means to the final destination. The route is guided by (G2).
[0046]
In addition, in FIG. 5, the prior destination setting process, the navigation start process by ignition, and the final destinationNon-vehicle movement route guidance processingIs executed as a series of processes, but can be executed independently. That is, when the final destination matches the vehicle destination, the non-vehicle movement route guidance process to the final destination is not executed. Further, the destination set in the advance destination setting process is always used in the navigation start process by ignition-on, but the advance destination setting process itself is not necessarily a process necessary for the navigation start process by ignition-on. The navigation start process by ignition on in the absence of the advance destination setting process can be executed. That is, in the first embodiment, the navigation start process by ignition-on is an essential process, and the advance destination setting process or / and the non-vehicle movement route guidance to the final destination are executed incidentally.
[0047]
Next, details of each operation by the devices constituting the above navigation system will be sequentially described.
(A) Destination setting operation
(A) First, the destination setting process in the portable information terminal 200 and the navigation device 100 provided with the destination setting programs 250 and 144 and the destination setting data 266 and 166 will be described. In the following description, processing by the portable information terminal 200 will be described. Similarly, in the navigation device 100, each part with the same name (each part with the same last two digits) is similarly performed.
When the destination setting is selected, the destination setting process is executed, and the arithmetic processing unit 201 (corresponding to the arithmetic processing unit 101 in the case of the navigation apparatus 100. The same applies to the other parts below) is displayed on the display unit 206. As the destination setting screen, for example, input methods of “designation from the area list”, “designation from the genre list”, “input telephone number”, and “input address” are displayed as images.
Then, of the four input methods displayed by the setter's input, after the cursor is moved to the display of the desired input method by the input unit 205 (joystick or key), the enter key is pressed, Is input by voice or the like, and the destination input method is selected.
When “designation from the area list” or “designation from the genre list” is selected, a classification list of areas and genres is read from the destination setting data 266 and displayed on the display unit 206. Here, after acquiring the selection of the area and genre selected by the setter, the name of the destination divided into the selected area and genre is displayed, and the destination is acquired.
Further, when “input telephone number” or “input address” is selected as the selection method, the telephone number or address is acquired by input from the input unit 205 (voice input or numeric keypad), etc. The destination is acquired from the correspondence between the telephone number or address stored in the data 266 and the destination.
[0048]
When the destination is acquired, the arithmetic processing unit 201 next checks whether or not there is a parking lot request and whether or not a departure date is specified. That is, a confirmation screen for the presence or absence of a parking lot is displayed to confirm the presence or absence of a request to the setter, and then a departure date and time input screen is displayed to confirm the departure date and time. When the transmission key is selected by the setter at the time when the destination is determined, it is handled that neither the parking lot request nor the departure date / time is specified.
[0049]
After the destination and, if selected, a parking lot request and / or departure date and time are confirmed, data such as the destination is transmitted to the information center 10 together with the ID of the corresponding navigation device by selecting a transmission key. .
In the case of a destination by the portable information terminal 200, the ID of the corresponding navigation device 100 may be registered in advance in the portable information terminal 200, or may be input individually when setting the destination. Also good. On the other hand, in the case of destination setting by the navigation device 100, the ID read from the ID data 162 is transmitted, but another ID may be designated by the input of the setter. By allowing other IDs to be specified, when the vehicle has two vehicles (and the navigation device 100), the destination for driving with one vehicle can be set from the other vehicle. it can.
[0050]
(B) Next, the destination setting process in the portable information terminal 200 and the navigation apparatus 100 that do not include the destination setting programs 250 and 144 and the destination setting data 266 and 166 will be described. Although the portable information terminal 200 will be described in this case as well, the navigation apparatus 100 operates in the same manner.
FIG. 7 shows a process when a destination is set in the information center 10 via the Internet using WWW browser software in a portable information terminal 200 (which is often a mobile phone or PHS) that does not have the destination setting program 250 or the like. It is a representation.
As a premise that the destination setting process shown in FIG. 7 is executed, a menu screen unique to each portable information terminal is displayed on the display unit 206 of the portable information terminal 200. This menu screen, other screens, The destination setting can be selected using the function keys. In the menu screen or the like, a navigation menu key (name is not limited as long as it is a destination setting key) is selected. As a menu screen unique to each portable information terminal 200, for example, in the case of a mobile phone, in addition to the “navigation menu” key, a “phone menu” key, a “data communication menu” key, etc. are displayed. In addition to the “navigation menu” key, a “schedule” key, an “address book” key, and the like are displayed.
In some cases, the key is selected by a dedicated key for setting a destination (a hard key such as a switch instead of a soft key selected by software from the display screen).
[0051]
The arithmetic processing unit 201 of the portable information terminal 200 monitors the selection of the “navigation menu” in the destination setting process, and starts communication with the information center 10 when the navigation menu is selected (step 10; Y). Then, the information center 10 is requested to transmit the navigation menu, and the navigation menu screen (Web information) transmitted in response to the request is acquired (step 11).
Then, the arithmetic processing unit 201 displays the acquired navigation menu screen on the display unit 206 (step 12). On this navigation menu screen, for example, keys for selecting various operations such as “1. Determine destination” key, “2. Search” key, and “3. Setting” key are displayed on the screen. Each of these keys is a software-selectable soft key. After selecting one of the keys displayed on the screen using the scroll key, or after specifying the number displayed before each key using the numeric keypad, press the select button. A key is selected by pressing it.
[0052]
When the “Determine destination” key is selected on the navigation menu screen (step 13; Y), the destination setting process is continued, and the arithmetic processing unit 201 requests the information center 10 to transmit a destination list. The destination list transmitted in response to this request is received (step 14).
Then, the arithmetic processing unit 201 displays the acquired destination list on the display unit 206 (step 15), and monitors and confirms the selection of the destination by the setter (step 16; Y). The confirmed destination (and the passing point if selected) and the ID of the navigation device 100 registered corresponding to the portable information terminal 200 are transmitted to the information center 10.
[0053]
Next, the arithmetic processing unit 201 receives the parking request confirmation screen transmitted from the information center 10 by transmitting the destination and the like, displays it on the display unit 206, and sets whether or not to set the destination. (Step 18). When the parking request is selected on the parking request confirmation screen (step 18; Y), the arithmetic processing unit 201 transmits the parking request to the information center 10 (step 19).
The departure date / time setting screen transmitted from the information center 10 is received when the parking request is not transmitted or the parking request is not issued, and is displayed on the display unit 206 to determine whether or not to set the departure date / time. An inquiry is made (step 20). When it is selected to set the departure date and time (step 20; Y), the arithmetic processing unit 201 displays a departure date and time designation screen on the display unit 206 (step 21), and the setting person inputs the departure date and time. Monitor (step 22).
When the departure date and time or the departure date is input and the confirmation key is pressed (step 22; Y), the arithmetic processing unit 201 transmits the confirmed departure date and time (or departure date) to the information center 10. (Step 23), the destination setting process is terminated.
[0054]
In the destination setting process described above, the case where the destination list is displayed on the screen of the display unit 206 has been described. However, since there are a large number of destinations that can be set, the conditions for selecting the destination are sequentially set. The final destination may be set by sequentially narrowing down the hierarchical destination information acquired and selected as Web information.
For example, after requesting / acquiring / displaying / selecting a region list, requesting / acquiring / displaying / selecting a genre list, and then requesting / acquiring / displaying / selecting a narrowed destination list may be performed. In this case, when the selected genre is further hierarchized, a genre request may be made a plurality of times until the genre at the lowest level is reached. Further, narrowing down by genre may be performed from the beginning without requesting the area list.
In addition, as a list of methods for determining the destination, "Determine by genre", "Determine by phone number", "Determine by address", "Determine by name", and "Determine by purpose" were requested / obtained / displayed and selected You may make it select the destination according to a system. When “Determine by name” is selected, destinations in the order of the Japanese syllabary are sequentially transmitted and displayed. This “determined by name” may be an item that can be selected after a genre or region is designated. When “Determine by purpose” is selected, for example, the purpose of vehicle travel such as “overnight trip”, “date”, “meal”, and the like is displayed.
[0055]
(C) Destination determination process
FIG. 8 is a flowchart showing the operation of the destination determination process performed in the information center 10 when the destination and ID are transmitted from the portable information terminal 200 or the navigation device 100. This destination determination process is executed when a destination is received. In addition to the case where the destination is set in advance before the vehicle departs, the case where the destination is set in the vehicle immediately before the departure, etc. It is executed including the case of.
[0056]
The arithmetic processing unit 14 of the information center 10 monitors the transmission of the destination from the user via the communication control unit 12 (step 31), receives the destination (step 31; Y), and uses the received destination as the final destination. Stored in the user data 50 of the corresponding ID as a place etc.(Step 32). That is, the received destination is stored in the final destination of the user data 50, and when a passing point, a parking lot request, and a departure date designation are also received, these are also stored in the user data 50 of the corresponding ID.
[0057]
Then, the arithmetic processing unit 14 determines whether or not there is a parking lot request in the received data (step 33; Y), and if there is a parking lot at the final destination (received destination). Is determined from the data attached to the destination setting data 48 (step 34).
When there is no parking lot at the final destination (step 34; N), the arithmetic processing unit 14 searches for parking lots existing around the parking lot using the parking lot data 52 (step 35), and uses the searched parking lot as a vehicle purpose. It is stored in the user data 50 of the corresponding ID as a place (step 36), and the process returns to the main routine by the system control program 26.
[0058]
On the other hand, when there is no parking lot request in the data received from the user (step 33; N), the arithmetic processing unit 14 determines whether or not the vehicle can travel to the final destination (step 37). When the vehicle can travel to the final destination (step 37; Y), and when there is a parking lot request and there is a parking lot at the final destination (step 33; Y, step 34; Y), the arithmetic processing unit 14 The final destination, that is, the destination received from the portable information terminal 200 or the navigation device 100 is stored as the vehicle destination in the user data 50 of the corresponding ID (step 38), and the process returns to the main routine. When the final destination is a point where the vehicle cannot travel (Step 37; N), the arithmetic processing unit 14 stores the nearest travelable point from the final destination as the vehicle destination in the user data 50 of the corresponding ID. Then (step 39) returns to the main routine. The arithmetic processing unit 14 determines whether or not there is a parking lot (step 34) and whether or not the vehicle can travel to the final destination (step 37).UCase and parking data52When a nearby parking lot is searched for (step 35), it is determined whether it corresponds to the region and period subject to the car regulations or vehicle regulations.
[0059]
In this way, the information center 10 stores the received destination as the final destination, and automatically sets the vehicle destination separately from the final destination. Therefore, there is no need to check if there is a parking lot when setting a destination, or to search for a nearby parking lot when there is no parking lot. It can be set as a destination.
For example, if you want to go to Myojin Pond in Kamikochi, the destination setter can set the Myojin Pond as a destination without having to check whether there are any car regulations or parking lots in Kamikochi. Since the Sawado parking lot is set as the vehicle destination as (or parking lot), the destination setting can be easily performed.
The movement from the vehicle destination to the final destination by means other than the vehicle (the host vehicle) can be reached by receiving the map picture created in the final destination search process described later by the portable information terminal 200. It becomes possible.
[0060]
(B) Route guidance to the vehicle destination
Next, the entire process for performing route guidance to the vehicle destination set in the information center will be described.
(A) Destination setting confirmation processing (on-vehicle device; navigation device)
FIG. 9 is a flowchart showing the operation of the destination setting confirmation process when the ignition is turned on in the vehicle device.
The navigation device 100 is automatically turned on in conjunction with the ignition being turned on. When the ignition is turned on (step 41; Y), the navigation device 100 immediately enters the information center 10 via the communication control unit 108. A destination confirmation request and an ID are transmitted (step 42), and the information center 10 waits for a destination confirmation result to be transmitted.
When the destination unset is received as the destination confirmation result from the information center 10 (step 43; N), the arithmetic processing unit 101 monitors whether or not the destination setting process is selected by the input unit 105 ( Step 44).
When the destination setting process is selected (step 44; Y), the arithmetic processing unit 101 executes the destination setting process by the on-vehicle device described above (step 45), and if the destination (and is set) A parking lot request and / or departure date / time) is transmitted to the information center 10 (step 46). When the destination is transmitted, the information center 10 executes the above-described destination determination process (FIG. 8).
Then, the arithmetic processing unit 101 receives the vehicle destination and final destination data 166 continuously transmitted from the information center 10, stores it in the data storage area 102B (step 47), and will be described later with reference to FIG. The request / route guidance process is executed (step 48), and the process returns to the main routine by the control program 154.
[0061]
On the other hand, when the destination of the destination confirmation request is received as the confirmation result for the destination confirmation request (step 43), the arithmetic processing unit 101 has already set the destination. The final destination data 166 is received and stored in the data storage area 102B (step 47), and the request / route guidance process is immediately executed (step 48).
As described above, when the destination is set in the information center 10 in advance, the user who gets on the vehicle performs a series of operations from turning on the power of the navigation device 100 to setting the destination by always turning on the ignition before starting the travel. Without any operation, it is possible to immediately execute the request / route search process and start traveling while receiving route guidance toward the destination.
[0062]
(B) Destination setting confirmation processing (information center)
FIG. 10 is a flowchart showing the operation of the destination setting confirmation process in the information center 10.
The arithmetic processing unit 14 of the information center 10 monitors the destination confirmation request from the navigation device 100. When there is a request (step 50; Y), the user data 50 of the corresponding ID is confirmed (step 51). It is confirmed whether the vehicle destination and departure date and time are stored (steps 52 and 53).
When both the vehicle destination and departure date / time are stored (step 52; Y, step 53; Y), it is further checked whether the stored departure date is today (step 54).
When the departure date is today (step 54; Y), and when the vehicle destination is stored but the departure date is not specified (step 53; N), the arithmetic processing unit 14 performs the destination setting confirmation process. As a confirmation result, the destination set already is transmitted to the navigation device 100 (step 55), and the set vehicle destination and final destination are further transmitted to the navigation device 100 (step 59). Then, a route search / guidance data transmission process (FIG. 11) described later is executed (step 60), and the process returns to the main routine by the system control program 26.
[0063]
On the other hand, when the vehicle destination is not stored in the user data 50 of the corresponding ID (step 52), and when the vehicle destination and the departure date / time are stored but are not today's departure (step 54; N), the calculation is performed. The processing unit 14 transmits the destination unset as a destination setting confirmation result to the navigation device 100 (step 56).
The arithmetic processing unit 14 monitors whether or not the destination setting process (step 45 in FIG. 9) has been executed in the navigation device 100 by the transmission without setting the destination and the destination has been transmitted (step 46 in the same) (step 46). FIG. 10; step 57). When the destination is received (step 57; Y), the destination determination process described with reference to FIG. 8 is executed (step 58), and the vehicle destination and final destination set in the destination determination process are displayed on the navigation device. 100 (step 59). Thereafter, route search / guidance data transmission processing is executed (step 60), and the process returns to the main routine.
When the destination is not received (step 57; N), it can be determined that the vehicle travels without the need for route guidance, so the arithmetic processing unit 101 terminates communication with the navigation device 100 without performing a route search or the like. (Step 61), the process returns to the main routine.
[0064]
Next, the route search / guidance data transmission process (FIG. 11) on the information center 10 side for dividing and transmitting the travel route searched to the vehicle destination in predetermined units, and the vehicle destination while sequentially requesting the transmission of the divided route A request / route guidance process (FIG. 12) on the navigation device 100 side that guides the route up to will be described.
[0065]
(C) Route search / guidance data transmission processing
As shown in FIG. 11, the arithmetic processing unit 14 of the information center 10 monitors whether or not a route guidance data acquisition request (request) has been received from the navigation device 100 (on-vehicle device) (step 65). Y), the current vehicle position included in the received information is extracted (step 66).
Next, when the requested road length is designated in the received information (step 67; Y), the designated requested road length is stored in the requested road length data 27 of the memory 18 (step 68), and is not designated. In this case (step 67; N), an initial value prepared in advance as the required road length is set in the required road length data 27 and stored (step 69).
[0066]
Next, the arithmetic processing unit 14 searches for a route from the vehicle current position to the vehicle destination (step 70). The route search is performed with reference to route search data 42 in the database 40, that is, intersection data, road data, and node data. This route search processing is known, and is performed by the method disclosed in, for example, Japanese Patent Laid-Open Nos. 1-173297 and 1-173298, and the condition that the route having the shortest distance is the optimum route is used. To set the recommended route.
In this embodiment, every time a request is received from the navigation device 100 (step 65; Y), a route from the vehicle current position to the vehicle destination is searched. In the information center 10, the external information collecting unit 70 obtains road information and traffic information such as traffic conditions and distances, traffic impossibility due to accidents, construction sections, etc. from the outside, and the database 40 is updated to the latest information. ing. For this reason, by performing a route search for each request from the vehicle side, a recommended route based on the latest data and its guidance data are always provided to the vehicle side, such as avoiding traffic congestion.
[0067]
Next, the arithmetic processing unit 14 executes the segment processing program 22 stored in the memory 18, and divides the travel route to the searched vehicle destination for each segment which is a unit of navigation (step 71). The unit to be divided may be a constant data size (for example, one segment is 1024 bytes), a road length is constant (for example, 1 km, 2 km, etc.). All the searched routes are divided into a divided route 1, a divided route 2,... As shown in FIG. Each divided path is one segment. As shown in FIG. 3B, each divided route data includes a data head, intersection information, road information, node information, landmark information, and the like.
[0068]
By segmenting such data, (i) even if the communication between the information center 10 and the navigation device 100 is interrupted, the route guidance can be performed as it is for the segment that has been transmitted at the time of the interruption. (Ii) There is an effect that retransmission may be performed from the segment that was being transmitted at the time of interruption. In other words, the segment is an information unit that can be decoded on the vehicle side. For example, if route / guidance data of 10 km is transmitted to the vehicle side as a single file as a whole and cannot be decoded on the vehicle side, route guidance cannot be performed for all of the 10 km. However, by dividing into 2 km segments and creating a file, the file can be decoded and route guidance can be provided for each segment.
[0069]
Next, the arithmetic processing unit 14 sequentially adds one segment closest to the vehicle position within the searched route range (step 72), and calculates the road length of the transmission road (step 73). That is, the transmission road length (total road length of the segment) = the transmission road length before the segment addition + the road length of the added segment is repeatedly performed to add the segments one by one.
Then, segments are added until the total transmission road length obtained by adding the lengths of roads included in each segment becomes longer than the requested road length stored in the user data 50 of the ID (step) 74; N).
[0070]
As a result, if transmission road length> requested road length (or transmission road length ≧ requested road length) (step 74; Y), the arithmetic processing unit 14 executes the guide data extraction program 24 stored in the memory 18. Referring to the guidance data 44 in the database 40, the guidance data in the range corresponding to the transmission road length is searched and extracted, and stored in the extracted guidance data 29 in the memory 18 (step 75).
The route data and the guidance data obtained as described above are transmitted to the navigation device 100 having the requested ID via the communication control unit 12 (step 76). At this time, the segmented route / guidance data is transmitted to the vehicle in order from the closest to the current vehicle position.
[0071]
(D) Request / route guidance processing
Next, a request / route guidance process executed by the navigation device 100 in response to the route search / guidance data transmission process by the information center 10 described above will be described with reference to the flowchart of FIG.
As shown in FIG. 12, the arithmetic processing unit 101 of the navigation device 100 transmits the current vehicle position and request (route guidance data acquisition request) and the requested road length to the information center 10 (step 80). Here, the requested road length is transmitted only when the requested road length data 168 is stored and for the first time.
[0072]
Then, the arithmetic processing unit 101 monitors whether or not the route / guide data (divided road data) divided according to the requested road length is received from the information center 10 (step 81). The route / guidance data 160 is stored in the memory 102, and the route guidance by the route guidance program 150 in the memory 102 is executed (step 82).
For example, the arithmetic processing unit 101 displays a route map or landmark on the display unit 106 as route guidance, and refers to the current position of the vehicle in the position measurement unit 104, before a predetermined distance from the intersection to be changed. The voice output unit 107 outputs voice guidance such as “the intersection about 200 m ahead is in the right / left direction”.
[0073]
In this embodiment, the route / guidance data received from the information center 10 is not the data of all the travel routes up to the vehicle destination, but the divided routes extracted from the travel routes newly searched for every request of the divided routes. To do. In the route search newly performed in response to the request, the latest traffic information and road information collected by the external information collection unit 70 are always used. Therefore, a route different from the travel route searched for at the time of departure may be extracted as a divided route due to a change in road conditions (congestion, accident, etc.) during travel. As described above, even when the road condition changes during the traveling, by receiving the divided route, it is possible to always receive and guide the current optimum route. In addition, it is possible to flexibly cope with a change of destination.
Furthermore, only a divided route having a route length (transmission road length) corresponding to a required road length required can be received from the information center 10, and data reception according to the memory capacity of the navigation device 100 is possible.
In addition, receiving the divided route corresponding to the requested road length reduces the amount of received data and completes the reception of the divided route in a short time. Can start early.
In addition, since a route search from the current vehicle position to the vehicle destination is performed for each request, for example, even when the vehicle deviates from the route, a request to the current vehicle position on the deviated road can be made. Route / guide data can be obtained, and driving can be performed with peace of mind.
[0074]
During route guidance, the arithmetic processing unit 101 acquires the current location of the vehicle from the position measurement unit 104 at predetermined time intervals, and the vehicle is a fixed distance (for example, 200 m) from the end of the divided route stored in the route / guidance data 160. It is monitored whether or not the front position has been reached (step 83). If it has not been reached (N), the process returns to step 82 to continue route guidance.
When the vehicle reaches the position a certain distance before the end of the divided route (step 83; Y), the arithmetic processing unit 101 determines whether or not the end of the divided route coincides with the vehicle destination. (Step 84). If the end of the divided path does not coincide with the vehicle destination (step 84; N), the process returns to step 80 to transmit the current vehicle position and request (route guidance data acquisition request) to the information center 10 again and to receive the next divided path. Continue route guidance.
[0075]
When the end of the divided path coincides with the vehicle destination (step 84; Y), the arithmetic processing unit 101 determines whether or not the vehicle has arrived at the vehicle destination (step 85), and has arrived at the vehicle destination. If not (Step 85; N), the process returns to Step 82 to continue route guidance.
On the other hand, when arriving at the vehicle destination (step 85; Y), the arithmetic processing unit 101 transmits the current vehicle position and arrival at the vehicle destination to the information center 10 (step 86). Return to routine.
Whether the vehicle has arrived at the vehicle destination is determined based on whether the vehicle has actually arrived at the vehicle destination or the last route guidance point by voice when the travel distance to the vehicle destination is within 500 m. It is determined that the vehicle has arrived at the vehicle destination when the position after passing (around the vehicle destination) is reached.
[0076]
(C) Route guidance to the final destination
Next, guidance to the final destination after the vehicle has arrived at the vehicle destination will be described.
(A) Final destination search process
FIG. 13 is a flowchart showing the operation of the final destination search process in the information center 10.
The arithmetic processing unit 14 of the information center 10 monitors the transmission of the vehicle destination arrival from the navigation device 100 (step 90), and when the vehicle destination arrival is received (step 90; Y), the vehicle current transmitted simultaneously. The position is stored in the user data 50 of the corresponding ID (step 91). Here, although the vehicle destination is stored in the user data 50, the current vehicle position is stored separately for the vehicle destination set in the destination determination process (FIG. 8) of the information center 10. This is because it may not be arrived, and for example, it may be possible to arrive at another parking lot or the like. In addition, since the vehicle destination is deleted at a predetermined time (vehicle destination arrival time, final destination arrival time, etc.) for the next destination setting, store the current vehicle position separately from the final destination. This is because the information center 10 can recognize the vehicle position in advance.
[0077]
The arithmetic processing unit 14 determines whether or not the stored current vehicle position matches the final destination (step 92). If they match (step 92; Y), the main routine by the system control program 26 is determined. Return to
On the other hand, when the current vehicle position is not the final destination (step 92; N), the arithmetic processing unit 14 searches for a route from the current vehicle position to the final destination in the non-vehicle mode (step 93). That is, the arithmetic processing unit 14 is a pedestrian-only road such as a pedestrian bridge or a pedestrian crossing used in the search in the non-vehicle mode, or a moving means (cable car, monorail, ropeway, train, train, ship, By using route search data 42 including data (station name, point data, distance between points, timetable, etc.) regarding routes that can be moved by buses, taxis, moving walkways, etc., the route to the final destination can be determined. Explore.
[0078]
Then, the arithmetic processing unit 14 creates a travel route based on the map picture using the map picture of the map picture creation data 54 in accordance with the travel route to the final destination searched (step 94).
FIG. 14 exemplifies a map picture to the final destination that is created by the information center 10 and can be moved only by walking.
As shown in FIG. 14, as a map picture, an entire route view including the current vehicle position M (displayed with a black symbol symbol in a circle) and the final destination PT (displayed with a symbol symbol ☆). a) and intersection diagrams (b) to (d) for the major intersections and intersections that turn left and right are created.
The road to be displayed is displayed as a straight line passing through each intersection. The road is displayed with a thickness corresponding to the actual road width. Both the overall route map (a) and intersection maps (b) to (d) of facilities (stations, hospitals, police boxes, schools, gas stations, hotels, restaurants, shrines, parks, etc.) that will be used as route guides along the way The symbol mark and / or name is displayed in the map picture. The landmark of the guidance data 44 may be used as the symbol mark of the facility serving as a landmark.
Also, in the entire route map, the intersection numbers assigned in the order of passing from the current vehicle position are displayed as circled numbers, and the intersection numbers with the specified numbers are displayed by specifying these numbers with the numeric keypad. .
In the intersection map, the same intersection number as the intersection number in the overall route diagram (a) is displayed as a circled number. Moreover, the advancing direction after passing through each intersection is indicated by an arrow P. In this way, instead of a detailed road map, a simple map picture composed of straight roads and symbol marks is created, so that the amount of data transmitted to the portable information terminal 200 is reduced and the image display area is narrow ( Even the display unit 206 with a small number of dots can be displayed. In addition, the symbol mark makes it easy to intuitively recognize the movement route to the final destination.
[0079]
FIG. 15 illustrates a map picture in the case of moving to the final destination using non-vehicle means such as a train other than walking. In the example in this figure, the final destination is Tokyo EQ-R (Equus Research Co., Ltd.), and the area from Hamamatsucho Station to Ochanomizu cannot be moved by vehicles due to road restrictions, etc. It is an example when a parking lot is set.
In such a case, the movement outline diagram in FIG. 15A, the entire route diagram in FIG. 15B, and an intersection diagram (not shown) (for example, FIGS. 14B to 14B) are created.
In the movement outline diagram of FIG. 15 (a), it is displayed that the vehicle travels from the Hamamatsucho station of the vehicle destination to Ochanomizu on the JR Yamanote line, and moves from Ochanomizu station to the final destination of Tokyo EQ-R on foot. As shown in FIG. 15A, when a means other than walking is used, a movement outline diagram is created, and the movement means and the movement section (movement facility name) by the movement means are displayed. Then, for the moving section by walking, an overall route diagram of FIG. 15B and an intersection diagram (not shown) are created as necessary.
In addition, each map picture is hierarchized, and is hierarchized in order of a movement conceptual diagram, a whole route map, and an intersection map. The movement concept diagram and the entire route diagram are further hierarchized in the same way as the intersection diagram when there are a plurality of diagrams in the same hierarchy, for example, a movement concept diagram (overall view) and a movement concept diagram (details). There may be.
[0080]
When the above map picture is created, the arithmetic processing unit 14 connects the line with the mobile terminal connection destination stored in the user data 50 of the corresponding ID (for example, by making a call), and reaches the created final destination. Is transmitted to the portable information terminal 200 (FIG. 13; step 95), and the process returns to the main routine by the system control program.
[0081]
(B) Route guidance by map picture of portable information terminal 200
When the mobile information terminal 200 receives the route / guidance data (map picture) 260 transmitted from the information center 10, the portable information terminal 200 stores it in the data storage area 202 </ b> B and displays the uppermost map picture among the received map pictures. To display.
Note that the display unit 206 may only display that a map picture has been received, and may display the map picture when the input unit 205 selects the map picture display.
After displaying the top layer map picture, the portable information terminal 200 displays the next screen when the next key or the next screen selection key (“→” key, “▽” key, etc.) is designated by the user. To do. In addition, when a number corresponding to a number displayed on the screen (a circled number in FIG. 14A) is designated with a numeric keypad, a corresponding intersection diagram is displayed.
[0082]
The user confirms the display screen of the portable information terminal 200, moves in the direction of the traveling direction arrow P displayed on the screen while taking correspondence between the actual target and the symbol mark, and displays the next screen according to the movement. It is possible to reach the final destination.
[0083]
The navigation device 100 according to the first embodiment described above has been described for the case where the navigation device 100 does not include the route search data and the route search program. However, the navigation device 100 may include the route search data and the route search program. Further, guidance data may be provided (Modification 11).
In this case, when the ignition is turned on, the navigation apparatus 100 transmits a destination confirmation request and an ID to the information center 10 to confirm whether or not the destination is set in advance.
When the destination is not set in the user data 50 corresponding to the ID in the information center 10 (including the case where the destination is not satisfied, but the destination is not set), the destination center is not set in the navigation device 100. Send to end communication. When the destination is set, the destination (or the vehicle destination and the final destination) is transmitted to the navigation device 100 and the communication is terminated.
[0084]
When the navigation device 100 receives a destination not set or a destination (or a vehicle destination and a final destination), the communication is terminated. When the destination (or the vehicle destination and the final destination) is received, the navigation device 100 searches for a travel route from the current vehicle position to the destination, and performs route guidance according to the searched travel route.
Also in the modified example 11, when the vehicle destination and the final destination (vehicle destination ≠ final destination) are received, the navigation apparatus 100 finishes the route arrival to the vehicle destination and the vehicle arrives at the destination. The current position is transmitted to the information center 10, and when the information center 10 receives the arrival at the destination, the map picture created by searching the non-vehicle movement route from the current position of the vehicle to the final destination in the non-vehicle mode is assigned to the corresponding ID. It transmits to the portable information terminal 200.
[0085]
In this modified example 11, the navigation apparatus 100 may be able to select a mode in which the route search to the destination is performed in the own apparatus and a mode performed in the information center (modified example 12).
In this case, for example, the navigation device 100 searches for a route with its own device when the destination is relatively close, and obtains a travel route early when the destination is far away (for example, when the distance is 100 km or more). Therefore, the travel route is received from the information center 10. When receiving a travel route, as described in the first embodiment, the request is made to the information center 10 and the divided routes are received in order to reflect the latest traffic information on all routes to the far destination. Can guide a simple route.
[0086]
Further, depending on the navigation device 100, the ignition destination may receive a preset destination (or vehicle destination and final destination) from the information center 10 and perform a route search to the destination or the like within the own device. The data may be received from the information center 10 for the purpose of supplementing data that is not used by the navigation device 100 with data used for guiding the travel route (Modification 13). For example, the navigation device 100 expands an intersection in order to reduce the size of the memory 102.FigureAvoid holding data. And the navigation apparatus 100IsEnlarge intersections on the travel route to the searched destinationReceived from the information center 10 for the purpose of supplementing data such as figures.
[0087]
In the first embodiment described above, the navigation apparatus 100 registered as a user in the information center 10 and assigned an ID has been described with respect to the navigation apparatus 100 described with reference to FIG. 1, but the configuration of each navigation apparatus is not necessarily limited. The navigation device described in the first embodiment, the navigation device described in Modification Example 11, and other various navigation devices having different programs, data, and functions may be used (Modification Example 14).
In this case, the navigation apparatus 100 transmits to the information center 10 transmission desired information specifying data for specifying information desired to be transmitted after confirming the destination setting to the information center 10 by turning on the ignition. In the information center 10, the destination, the vehicle destination and the final destination, the entire travel route to the destination or the final destination, the divided route to the destination or the final destination (the first route) according to the desired transmission information designation data. , Etc. are transmitted in response to a request on the divided path described in the embodiment.
[0088]
The destination determination process (FIG. 8) described in the first embodiment has been described when the information center 10 receives the destination and the ID. However, the destination determination process is performed when the destination is received. If the destination is set in advance, it may become impossible to reach the set vehicle destination due to a change in traffic regulations or the like until the departure date and time.
Therefore, the destination determination process may be executed when the first request is met or when the destination confirmation request is met (Modification 15). This makes it possible to determine the optimum vehicle destination and final destination at the departure date and time.
[0089]
Even in the case of the modification 15, for example, there is a possibility that the parking lot set as the vehicle destination becomes full and cannot be parked.YesIn such a case, even in the modified example 15, the vehicle destination cannot be reached. Therefore, the information center 10 may perform the destination determination process including the full information on the parking lot whenever there is a request for the divided route based on the traffic information collected by the external information collecting unit 70. Good (Modification 16). Further, the destination determination process may be executed when the vehicle arrives within a predetermined distance (for example, 10 km) from the initially set vehicle destination (Modification 16 ′).
[0090]
In the first embodiment described, in the final destination search process (FIG. 13), the travel route from the current vehicle position to the final destination is searched in the non-vehicle mode (step 93), and a map picture of the travel route is created. (Step 94), the map data including the vehicle destination and the final destination, and the data of the vehicle destination point and the final destination point are transmitted to the portable information terminal 200 (step 95). 200 may be transmitted (Modification 17).
[0091]
In the final destination processing (FIG. 13), the vehicle destination arrival is received,Vehicle current positionIs not matched with the final destination, the route search in the non-vehicle mode (step 93) and the creation of the map picture (step 94) are performed every time. A picture map for the final destination may be created in advance and stored in the database 40 together with the combination of the vehicle destination and the final destination (Modification 18). In this case, the information center 10 searches whether or not the combination of the vehicle destination and the final destination corresponding to the received current vehicle position is in the database 40, and if not, executes Steps 93 and 94 in FIG. If there is, the picture map stored with the combination is read and transmitted to the portable information terminal 200 (step 95).
[0092]
In the final destination process (FIG. 13), when the map picture is created, the arithmetic processing unit 14 connects the line with the mobile terminal connection destination of the corresponding ID (for example, by making a call), and creates the final destination created. Although the map picture up to the ground is directly transmitted to the portable information terminal 200 (step 95), the created map picture data may be transmitted as an email to the mail address of the corresponding ID (modified example) 19).
In this case, the mobile information terminal 200 or other information processing apparatus can be used to download and display data such as a map picture from its own mail address.
[0093]
(3) Second embodiment
Next, a second embodiment will be described. Note that the configurations of the information center 10, the navigation device 100, and the portable information terminal 200 in each of the second and subsequent embodiments are substantially the same as those in the first embodiment, and therefore different configurations from the first embodiment will be described. The same parts are omitted as appropriate.
In the first embodiment, the destination can be set in advance in the information center 10 before the vehicle departs, but the setting destination is only for the user data 50 of one person (mainly own ID). Only set the destination. However, there are cases where a plurality of vehicles travel toward the same destination at the same date and time, as in the case of golfing with a plurality of members. In such a case, according to the first embodiment, it is necessary to repeat the presetting of the same destination number of times for each member, and redundant operations are duplicated.
[0094]
Therefore, in the second embodiment, destination setting for a plurality of members can be performed by one destination setting by one person. That is, in the second embodiment, the destination setting is performed in a broadcast manner.
Therefore, the portable information terminal 200 and the navigation device 100 according to the second embodiment include the destination transmission member setting processing program according to the present embodiment and the candidate list data of members for setting the destination, or the information center. WWW browser software for acquiring a member candidate list screen for selecting a destination transmission member from 10 as Web information.
On the other hand, in the information center 10 in the second embodiment, the destination determination program for the second embodiment is stored in the memory 18 instead of the destination determination program 25, and the member candidate list is stored in the database 40. . The member candidate list is stored in the corresponding user data 50 for each user of each ID.
[0095]
FIG. 16 is a flowchart showing the operation of the destination transmission member setting process executed in portable information terminal 200 and navigation device 100. In the following description of the operation, the processing is performed by the portable information terminal 200, but the same processing is performed in the navigation device 100. In this case, similarly to the destination setting process in the first embodiment, the description of the operation of each unit of the portable information terminal 200 is the operation of each unit of the navigation device 100 in which the last two digits are the same. For example, the arithmetic processing unit 201 in the portable information terminal 200 corresponds to the arithmetic processing unit 101 in the navigation device 100.
[0096]
The arithmetic processing unit 201 first executes destination setting processing (step 101). This destination setting process is the same as the destination setting process described in the first embodiment. When the portable information terminal 200 includes the destination setting program 250 and the destination setting data 266, the destination setting process is performed. The destination selected from the data (including parking request and departure date / time) is transmitted to the information center 10.
On the other hand, when there is no such program or data, the destination setting process based on the Web information described with reference to FIG. 7 is performed. In this case, including other processing, a selection screen on which keys and items are displayed for selecting necessary items, a user list, and the like are also acquired from the information center 10 using Web information, and the selected items and data are stored in the information center 10. Will be sent to. Hereinafter, the case of having a program and data will be described, but the same applies to the case of using Web information.
In addition, when the broadcast setting of the destination according to the present embodiment is performed, the normal departure date and time is set in this destination setting process, but there is a case where it is set on the day of departure, so the setting of the departure date and time exists. Is not necessarily a mandatory setting.
[0097]
Thereafter, the arithmetic processing unit 201 determines whether or not “member setting” is selected from the display screen by the user (step 102). The display of the selected key may be other display such as “Send to other person”.
When the member setting is not selected (step 102; N), the process returns to the main routine by the control program 254.
On the other hand, when the eye setting is selected (step 102; Y), the arithmetic processing unit 201 acquires a member candidate list from the data storage area and displays it on the display unit 206 (step 104).
FIG. 17 shows an example of a display screen displayed on the display unit 206 in the present embodiment. (A) is a destination transmission member setting screen on which a candidate list of members is displayed, and (b) is a new member. The setting screen, (c) shows a mail screen transmitted to a user whose destination is set by another person.
As shown in FIG. 17A, on the destination transmission member setting screen, a user list unique to the destination setter is displayed. In other words, the other party who has set a destination for another person in the past, the other person who has set his or her destination, or another person who has set a separate member may send a destination. It is registered in the data storage area 202B as a member candidate. A candidate list of registered members is displayed. Then, on the destination transmission member setting screen, as shown in FIG. 17A, the user name and the user ID are displayed.
A number is displayed in front of each user name. By specifying this number with the numeric keypad, the corresponding display location is highlighted or selected by touching the display location or by operating the cursor movement key. Thus, when a user name is selected, a check mark (displayed with a dot) indicating that the user name has been selected is displayed in the left frame of the selected user name.
[0098]
In this manner, the destination setter selects a member who sets the destination on the destination transmission member setting screen. If no member is displayed in the currently displayed member candidates, other member candidates are displayed in the same manner by selecting “0th screen” in the same manner.
When a new member not registered in the destination setter member candidate list is selected, the “#new member” key illustrated in FIG. 17A is selected.
When the arithmetic processing unit of the portable information terminal 200 detects the selection of the “#new member” key (step 105; Y), a new member setting screen shown in FIG. 17B is displayed on the display unit 106 (step 106). ).
The destination setter specifies a new member who sets the destination on the new member setting screen. Input items for specifying a new member include the ID, name, email address, telephone number, and recitation number of the new member. In this embodiment, it is not necessary to input all these items. In order to specify a member (user), input of at least two items of ID and another item is required. However, three or more items, four or more items, or all items may be requested in order to perform user authorization more accurately. Alternatively, only one item may be accepted, and when the user cannot be specified with this one item, the input of another item may be requested.
[0099]
When the “* confirm” key is selected by the destination setter after selecting the destination transmission member on the above destination transmission member setting screen or new member setting screen, the arithmetic processing unit detects this (step 107; Y), the ID of the destination transmission member selected at the time of confirmation is transmitted to the information center 10 (step 108).
When a new member is set, other items input together with the ID are also transmitted.
The set new member is automatically registered in the user candidate list for the destination setter.
[0100]
FIG. 18 is a flowchart showing the destination setting process of this embodiment performed in the information center.
The arithmetic processing unit 14 of the information center 10 performs processing from user destination reception monitoring (step 31) to vehicle destination storage (steps 36, 38, 39). The processes in steps 31 to 39 are the same as steps 31 to 39 in the destination determination process described with reference to FIG.
After the above processing, the arithmetic processing unit 14 confirms whether or not the member ID is transmitted together with the destination or after the destination, and if there is a member ID (step 120; Y), the user data of each member ID The vehicle destination and the final destination are stored in 50 (step 121).
[0010]
The arithmetic processing unit 14 automatically creates an email indicating that the destination has been set by another person from the user data 50 regarding the destination setter and the received data such as the destination for the user of each member ID. And transmit (step 122). When sending an email, the email address stored in the user data 50 of the corresponding ID is used.
FIG. 17C illustrates the mail created by the arithmetic processing unit 14. As illustrated in FIG. 17 (c), the name of the destination setter is used for “Takahashi Takahashi” in the first row, and the departure date and time is used for the date and time portion in the third row. The destination name is used for the part of the eye, the destination setter “Mr.” is used for the part “Takahashi” on the fifth line, and “Home” on the fifth line is the current vehicle position of the user data Is used, and the departure date and time is used as the scheduled departure time on the sixth line.
In addition, the description below “details” on the last line is a URL (Uniform Resource Locators) for acquiring the target file and displaying it in the Web browser.
A user who has received an e-mail from the information center 10 (the receiving device may be a personal computer, a navigation device 100, etc. in addition to the form information terminal 200) designates this URL, thereby allowing another person (FIG. 17 (c)). ) Allows you to edit your destination settings set by Takashi Takahashi). For example, when another member A is placed on the way between the set destinations, the home of the member A can be set as a passing point.
As described above, the data related to the destination edited for the user after designating the URL displayed in the mail is stored in the user data 50 of the corresponding ID edited by the information center 10.
[0101]
After sending the mail to the user of each member ID, the arithmetic processing unit 14 determines whether or not a new member for the destination setter is set (step 123). Whether or not the member is a new member is determined based on whether or not a member ID not in the member candidate list stored in the user data 50 corresponding to the destination setter ID is received.
When a new member is set (step 123; Y), the arithmetic processing unit 14 stores the name and ID of the new member in the destination candidate's member candidate list (step 124), and the control program 254. Return to the main routine.
[0102]
As a result of the above processing, a user whose destination is set by another person (user B) can confirm that the destination is set by checking the mail addressed to himself / herself.
Then, as in the case where the user B himself / herself presets the destination in the information center 10, the user B turns on the ignition on the date set by the other person to thereby perform the destination setting confirmation processing (FIG. 9) A request / route guidance process (FIG. 12) is executed, and if the vehicle destination and the vehicle destination are different points, a map picture of the non-vehicle route is further received by the portable information terminal 200.
As described above, according to the second embodiment, destinations for a plurality of members including oneself are registered in the user data 50 of the information center 10 by one destination setting by one destination setter. Can do.
[0103]
In the second embodiment described above, the information center 10 transmits the mail illustrated in FIG. 17C to each received member ID. However, when there is a member that cannot transmit the mail, the information center 10 transmits the mail. You may make it notify that the member who was not able to exist, member ID, and a name with respect to the portable information terminal 200 or the navigation apparatus 100 which set the destination (modification 21). In the portable information terminal 200 or the like that has received this, the presence of a member that could not be sent by e-mail and the name and ID of the member are displayed on the display unit. By confirming this display, the destination setter can notify the member that the destination has been set or that the mail could not be sent by means other than e-mail, for example, telephone.
[0104]
Moreover, in 2nd Embodiment demonstrated, it was made to store in the same area of the user 50, without distinguishing between the destination set by others and the destination set by the self, It may be stored (Modification 22).
In this case, when the destination setting confirmation process is performed, the information center 10 sets the destination set by the other person to the user who has requested the destination setting confirmation if the set destination is set by another person. It is confirmed whether or not it is possible to transmit route / guide data to the destination (vehicle destination). The information center 10 performs route search / guidance data transmission processing (FIG. 11) when confirmation from the navigation device 100 that the destination set by another person is acceptable is transmitted.
[0105]
(4) Third embodiment
Next, a third embodiment will be described.
In the described first embodiment, the information center 10 searches for a non-vehicle route from the vehicle destination to the final destination and transmits a map picture to the portable information terminal 20 so that the user of the portable information terminal 20 can walk or the like. To reach the final destination.
In the third embodiment, separately from or in addition to the first embodiment, the current position of the vehicle on which the navigation device 100 is mounted is determined from the current position of the portable information terminal 200 for which the destination is preset. The non-vehicle route up to is searched and a map picture is transmitted to the portable information terminal 200. It should be noted that the destination setting process performed in advance can include a case where the destinations of other users described in the second embodiment are set in advance at the same time.
[0106]
FIG. 19 shows an example of data exchange between the information center 10, the navigation system 100, and the portable information terminal 200 in the present embodiment.
As indicated by an arrow E0 ′ in FIG. 19, the portable information terminal 200 sets the destination and the current position by the operation described in the first embodiment.
When the portable information terminal 200 includes a GPS receiver, the current position is set as a current position by a coordinate value specified by latitude and longitude specified by the GPS receiver. When a position measuring unit such as GPS is not provided, the address or telephone number of the place input by the user (destination setting person) is set as the current position.
In the case of the portable information terminal 200 having the destination setting data 266, the current facility or the like is designated from the destination setting data 266 in the same manner as the destination setting process by the destination setting program 250. Is set as the current position. In this case, the destination setting program designates a facility or the like by a genre or the like as described in the first embodiment, and then selects “Set to destination”, “Set to transit point”, or “Set to current position”. By selecting, it is determined whether to set the destination, waypoint (passing point), or current position.
Further, when the portable information terminal 200 performs destination setting for the information center 10 via the Internet using the WWW browser software, as shown in FIG. To set the current position.
[0107]
When the portable information terminal 200 sets the destination and the current position by any of the methods described above as indicated by an arrow E1 ′ in FIG. 19, the portable information terminal 200 transmits the set destination, the current position, and the ID to the information center 10.
When the data such as the destination is received, the information center 10 determines whether or not the current position of the portable information terminal 200 is included in the received data, as indicated by an arrow E2 ′. Similar to the first embodiment, the destination determination process (FIG. 8) is executed, and the final destination and the vehicle destination are stored in the user data 50 of the corresponding ID.
[0108]
On the other hand, if the current position is included in the received data, it is determined that there is a request for searching for a moving route to the vehicle destination, and the current vehicle position is read from the user data 50 corresponding to the received ID. The route search from the received current position of the portable information terminal 200 to the current vehicle position is executed in the non-vehicle mode.
That is, the arithmetic processing unit 14 of the information center 10 uses a pedestrian-only road such as a pedestrian bridge or a pedestrian crossing used in the search in the non-vehicle mode, or a moving means other than a vehicle or a walk (cable car, monorail, ropeway, train, Vehicles from the current location using route search data 42 including data (station names, point data, distances between points, timetables, etc.) regarding routes that can be moved by trains, ships, buses, taxis, moving walkways, etc. The travel route to the current position is searched.
Then, the arithmetic processing unit 14 of the information center 10 uses the map picture of the map picture creation data 54 according to the searched travel path to the final destination, and uses the map picture illustrated in FIGS. As shown by the arrow E 3 ′, the created guidance data with the map picture to the vehicle destination is transmitted to the portable information terminal 200.
The mobile information terminal 200 that has received the map picture guides the route by the non-vehicle means to the vehicle destination by sequentially displaying the received map picture according to the user's operation (E4 ').
[0109]
In the information center 10 in the third embodiment, it is necessary to be able to always recognize the current vehicle position. Therefore, the navigation device 100 acquires the current vehicle position from the position measurement unit 104 and transmits it to the information center 10 when the vehicle ignition is off. The information center 10 can always recognize the current position of the vehicle by storing the transmitted vehicle current position in the user data of the corresponding ID.
[0110]
As described above, according to the third embodiment, the user of the portable information terminal 200 can easily set the destination for the navigation device 100 and receive the map picture from the current position to the current position of the vehicle. The current position can be reached.
Thus, since the map picture (non-vehicle movement route) up to the current vehicle position can be received, even when going to an unguided place, it is possible to move away from the vehicle with peace of mind.
[0111]
In the third embodiment described above, the mobile information terminal 200 transmits the current position to the information center 10 instead of the movement route search request. However, the information center 10 transmits the request data for the movement route search to the vehicle current position together with the current position. (Modification 31). In this case, the information center receives the request data for the travel route search together with the current position of the portable information terminal 200, thereby executing the travel route search in the non-vehicle mode up to the current vehicle position.
[0112]
In the third embodiment described above, the case where the destination for the navigation device 100 is set in advance from the portable information terminal 200 has been described as an example. You may make it perform the search of the movement path | route by the non-vehicle mode from the present position of the information terminal 200 to a vehicle present position (modification 32).
In this case, the portable information terminal 200 transmits to the information center 10 a current position that also serves as a request for non-vehicle movement route search to the current position and vehicle current position, or a request for non-vehicle movement route search to the vehicle current position. .
On the other hand, if the information center 10 receives a current position that also serves as a request for a non-vehicle movement route search to the current position and the vehicle current position, or a request for a non-vehicle movement route search to the vehicle current position, Without performing the determination process (FIG. 8), the above-described search for the non-vehicle mode movement route from the current position to the current vehicle position and a map picture are created and transmitted to the portable information terminal 200.
[0113]
Furthermore, a facility or a spot other than the current vehicle position may be set as the destination of the portable information terminal 200, and a travel route to this destination may be searched in the non-vehicle mode (Modification 33).
In this case, the mobile information terminal 200 requests the destination, the data indicating that the destination is the destination of the mobile information terminal 200, the current position, and the request for the travel route search in the non-vehicle mode (the current position is this). Request may be shared) to the information center. The setting of the destination by the portable information terminal 200 is performed by any one of the methods described in the first embodiment.
The information center 10 searches for the non-vehicle mode travel route from the current position to the vehicle current position and creates a map picture and transmits it to the portable information terminal 200 without performing the destination determination process (FIG. 8). .
[0114]
(5) Fourth embodiment
Next, a fourth embodiment will be described.
In the first embodiment described above, when the vehicle (navigation device 100) gets off the vehicle that has arrived at the vehicle destination and heads for the destination by walking or the like, the vehicle (navigation device 100) notifies the information center 10 of the current vehicle position when the vehicle destination arrives. Based on this, the server sends a simplified guide map (map picture) to the final destination to the mobile phone.
However, if the arrival point of the vehicle (usually the vehicle destination) is a place where radio waves for communication such as an underground parking lot do not reach, the navigation device 100 notifies the information center 10 of the current vehicle position and the arrival of the vehicle destination. You may not be able to.
In the fourth embodiment, when it is impossible to communicate with the information center 10 at the final vehicle arrival point, the mobile current terminal 200 is transmitted to the mobile information terminal 200 and moved to a communicable point. The vehicle arrival and the current vehicle position are transmitted to the information center 10.
[0115]
FIG. 20 illustrates an example of data exchange between the information center 10, the navigation system 100, and the portable information terminal 200 in the fourth embodiment.
A process of setting the destination of the navigation device 100 from the portable information terminal 200 to the information center 100 (arrows E0 to E2), and a destination setting confirmation process (ignition on (arrow F0) of the vehicle on which the navigation device 100 is mounted) ( Arrows F1 to F4; FIGS. 9 and 10), split route request (navigation device 100) and route / guide data transmission (information center 10) processing (arrows F5 to F9,...) Are the same as in the first embodiment. It is.
[0116]
When data cannot be transmitted to the information center 10 when the navigation device 100 arrives at the destination, the arithmetic processing unit of the navigation device 100 is a position measurement unit 104 as indicated by an arrow Fn-2 ′ in FIG. The measured vehicle current position is transmitted to portable information terminal 200. The vehicle current position is transmitted by wireless communication such as infrared communication or SS (spread spectrum) communication, wired communication such as serial communication or parallel communication, packet switching method, or circuit switching method.
When the communication with the information center is based on the packet switching method, the navigation device 100 unilaterally terminates the communication with the information center 10 when the current vehicle position is transmitted to the portable information terminal 200.
[0117]
When the mobile information terminal 200 receives the current vehicle position from the navigation device 100, the mobile information terminal 200 stores the received current vehicle position in the data storage area 202B, as indicated by an arrow Fn-1 'in FIG.
Then, after carrying the portable information terminal 200 away from the vehicle and moving to a place where communication with the information center 10 is possible, the user moves the vehicle from the portable information terminal 200 to the information center 10 as indicated by an arrow Fn ′. The current position, ID, and vehicle destination arrival are notified.
[0118]
On the other hand, when receiving the current vehicle position, ID, and arrival at the vehicle destination from the portable information terminal, the information center 10 stores the current vehicle position in the user data 50 of the corresponding ID as shown by the arrow G0 and The travel route is searched from the vehicle to the final destination in the non-vehicle mode. This search for the travel route is the same as the final destination search process (FIG. 13) described in the first embodiment. Then, as shown by the arrow G1, the map picture created by the final destination search process is transmitted to the portable information terminal 200.
In the information center 10, when the communication with the navigation device 100 is based on the packet switching method, the communication is unilaterally terminated when the current vehicle position or the like is received from the portable information terminal 200.

[0120]
FIG. 21 shows a request / route guidance process in the fourth embodiment.
As shown in FIG. 21, in the request / route guidance process in the fourth embodiment, the processes from step 80 to step 85 are the same as those in the first embodiment (see FIG. 12).
When the vehicle arrives at the vehicle destination (step 85; Y), the arithmetic processing unit 101 of the navigation device 100 determines whether or not communication with the information center 10 is possible (step 130), and communication is possible. If so (step 130; Y), as in the first embodiment, the vehicle current position and arrival at the vehicle destination are transmitted to the information center 10 (step 86), and the control program 154 returns to the main routine. .
On the other hand, when communication with the information center 10 is not possible, the arithmetic processing unit 101 transmits the current vehicle position measured by the position measurement unit 104 to the portable information terminal 200 and forcibly ends communication with the information center 10. (Step 131), the process returns to the main routine.
[0121]
As described above, according to the fourth embodiment, the current position (vehicle current position) can be acquired even by a portable information terminal that does not include a current position detection device such as a GPS receiver.
The vehicle current position acquired from the navigation device 100 can be used as the current position of the portable information terminal 200 in Modification 33 of the third embodiment (Modification 41). The portable information terminal 200 requests the information center 10 for a travel route based on a map picture from a current position (= current position of the vehicle) to an arbitrary destination (a destination moved by non-vehicle means).
[0122]
In the third embodiment, the vehicle current position is transmitted from the navigation device 100 to the information center 10 with the ignition off. However, the fourth embodiment can be applied to this third embodiment as well (modified example). 42).
In other words, when communication with the information center 10 is not possible when the ignition is off, the navigation device 100 transmits the current vehicle position to the portable information terminal 200. The user transmits the current vehicle position from the portable information terminal 200 to the information center 10 after moving to a place where communication is possible.
Thereby, even when the ignition is turned off in an area where the vehicle cannot communicate, the information center 10 can store and recognize the current vehicle position.
[0123]
In the fourth embodiment, the navigation device 100 transmits the current vehicle position to the portable information terminal 200 when arriving at a vehicle destination or the like. However, the navigation device 100 is always at regular intervals (for example, every 5 minutes, n minutes). The vehicle current position may be transmitted to the portable information terminal 200 at a necessary timing or in response to a user request (variation 43). The necessary timing includes, for example, the timing of traveling a predetermined distance (for example, 100 m, 200 m, 500 m, etc.), the timing of changing the course of an intersection, the timing of ignition off, and the like.
In this case, the current position of the portable information terminal 200 in the modified example 33 (= the current vehicle position) is also obtained in the case where the vehicle is temporarily parked in the middle of the travel route and goes out to a specific destination (the destination moved by the non-vehicle means). ) Can be used.
