Description

  The present invention relates to a portable navigation device, a navigation server, and a navigation system in a so-called multimodal navigation system that totally guides routes such as walking, trains, and subways.

  Mobile navigation devices that display a route to a destination as a map on a mobile phone terminal device, for example, a display screen of a mobile phone, have become widespread, and the route to the destination spans a plurality of transportation means such as walking → train → walking. It has become possible to provide appropriate route guidance to users. This type of portable navigation device obtains current location information by GPS and is used as a starting point for route search.

  Moreover, there is a conventional technique described in the following Patent Document 1 (Japanese Patent Laid-Open No. 2002-298169) as a means for searching for a train route from a station. In this prior art, the portable navigation device acquires information transmitted from the automatic ticket checker when passing through the automatic ticket checker, and performs route search using this information. In addition, as one application of using the position information obtained by the GPS positioning system, the information on the departure point and the destination is sent from the portable terminal to the information distribution server, and the information distribution server uses the shortest route from the data of the road network and the traffic network. A navigation device that searches and guides users has been put into practical use. As a route search method in such a navigation system, the Dijkstra method (label determination method) is used. The following Patent Document 2 (Japanese Patent Laid-Open No. 2001-165681) discloses an outline of a route search method using the Dijkstra method.

JP 2002-298169 A JP 2001-165681 A (FIG. 1, paragraphs [0003] to [0010])

  When moving to a destination using a plurality of types of moving means, for example, when taking a route of walking → train → walking, it has been found that the user does not necessarily perform route search in the first stage. If you are in a hurry, you will often leave for the nearest station first, rather than searching for the route first. Because the route to the nearest station is well known, route guidance is not necessary, and it is generally known which train to ride. Moreover, since it is difficult to operate a portable mobile terminal device such as a mobile phone while walking, the route search to the destination is often performed after waiting for a train at the nearest station or after getting on the train.

  Once you get on the train, you have time to calm down, so it is convenient to search for a route to your destination. Or you may know the route but want to find out when it will arrive.

  However, if a route search operation is performed when riding a train, a conventional mobile navigation device that starts searching from a walking route displays a route search result as shown in FIG. 13, for example. FIG. 13 is a diagram illustrating an example of a result of a route search performed immediately after departure on an 18:30 train from Kanda Station.

  Since the current location at the time of the route search is on the track between Kanda Station and Tokyo Station, if the mobile navigation device does not know that the user is on the train, the mobile navigation device is GPS The starting point S is the position map-matched to the road near the obtained current location. In this case, as shown in FIG. 14, since the route starts from the departure point S to Kanda Station (Goal G) on foot, the train from Kanda 18:39 is searched. Between 18:30 and 18:39, there is also a train that departs at 18:35, and the time of the train that deviates from the actual train is displayed.

  If you want to know when to get to your destination, this makes no sense. In addition, since the train that is actually on board is different from the train that has been searched for, the types of trains such as high speed, semi-express, and limited express trains and their destinations are also problematic.

  In addition, as in the conventional portable navigation device described in Patent Document 1, a device that starts a route search based on information that has passed through an automatic ticket gate has the following problem.

  If the information of the time and the station name that passed through the automatic ticket gate is acquired, and the route search is performed based on the information, the time that passed the automatic ticket gate and the time that can be boarded may not be directly connected. Patent Document 1 states that a predetermined time after the passage time may be set as the departure time. However, the predetermined time is not constant, and in the following cases, there is a deviation from a train that can be actually used.

(B) When the distance between the automatic ticket gate and the boarding line is far (b) When stopping at a store, restaurant, toilet, etc. after entering the automatic ticket gate For (b) above, for example, at the same station at the west and east gates The predetermined time to the boarding line varies greatly depending on the mouth. For example, if you enter the Tokyo Station Marunouchi North Exit and get on the Keiyo Line, it takes a long time because it is very far away, but it takes a short time because the platform on the Chuo Line is close. Therefore, it is not in practice to set the departure time uniformly after a predetermined time from the automatic ticket gate passing time. Furthermore, as shown in (b), when the user stops at a store, the actual boarding time is unpredictable, and the difference from the automatic ticket gate passing time may be large.

  In the case of the prior art described in Patent Document 1, the route search process is triggered by the automatic ticket gate passing as a trigger. Therefore, if the passing time of the automatic ticket gate and the actual train boarding time are indefinite, the accuracy is high. The route cannot be searched.

  Further, in the case of the prior art described in Patent Document 1, when the mobile mobile terminal device detects passing through the automatic ticket gate, the passage time information is acquired from the clock means provided in the mobile mobile terminal device. The clock means of the portable mobile terminal device may have an inaccurate time, and depending on the mobile phone communication system, the time may not be corrected automatically, or automatic correction may be prohibited depending on the setting. May have an error. If the information on the passage time is inaccurate, the departure time of the route search becomes an incorrect time.

  FIG. 1 is an overall configuration diagram of a navigation system according to an embodiment of the present invention. The navigation system shown in the figure moves between a mobile mobile terminal device 1 equipped with navigation application software (hereinafter abbreviated as “navigation app”) that realizes a mobile navigation device, and a route search server (navigation server) 40. It is configured by connecting via the communication network 20 and the Internet network 30.

  A mobile mobile terminal device 1 such as a mobile phone includes a GPS receiving unit 2 that detects the current position by satellite navigation, an operation unit 3 that performs a dial operation, a scroll operation, a selection operation, and the like of the mobile mobile terminal device 1, and an automatic station A non-contact IC chip 4 that performs short-range wireless communication with the automatic ticket gate 25 when passing through the ticket gate 25 to perform fare settlement processing, a control unit 5 that executes communication control and a navigation application, and data A storage unit 6 that stores information, a communication unit 7 that communicates with the mobile communication network 20, and map data or the route search that is acquired from the route search server 40 by executing the navigation application and temporarily stored in the storage unit 6 And a display unit 8 for displaying the result on the screen 8a.

  The route search server (navigation server) 40 is a server system (information distribution computer system) operated by a content distribution company, and includes an information distribution unit 41 that performs communication with the Internet 30, and the mobile mobile terminal device 1. When a route search instruction is received, a route search unit 42 that performs a search process for an optimal route and returns a search result and corresponding map data to the portable mobile terminal device 1 and a map database 43 that stores map data for each area are provided. . The route search unit 42 of this embodiment includes a timetable database (operation time database) 42a of various transportation facilities, and performs route search processing using the timetable database when a transportation facility enters the searched route. .

  FIG. 2 is a diagram illustrating a screen display example of the display unit 8 when the navigation application is activated in the mobile mobile terminal device 1 according to the present embodiment. In order for the navigation application installed in the portable mobile terminal device 1 to request a route search from the navigation server 40, at least three inputs of a departure place, a destination, and a search condition are required. FIG. 2 shows an input screen for inputting “departure location (current location)”. The departure location input screen in the present embodiment is provided with a selection item “During boarding” 11. This “on board” 11 is selected by the user when the user searches for a route while riding on public transportation.

  FIG. 3 is a flowchart showing a processing procedure executed by the navigation application when “during boarding” 11 shown in FIG. 2 is selected by the user. When “on board” 11 is selected on the screen of FIG. 2 (step S100), it is next checked whether or not the previous ticket gate information has been acquired (step S101).

  Here, the ticket gate information includes station name information and ticket gate passage time information. There are the following three methods for obtaining ticket gate information.

(First method for obtaining ticket gate information)
The mobile mobile terminal device 1 according to the embodiment shown in FIG. 1 has a non-contact IC chip 4 mounted thereon, and the non-contact IC chip 4 performs data communication with an automatic ticket gate 25 to charge and settle a fare. Process. Such a portable mobile terminal device 1 is generally called a FeliCa (registered trademark) cell phone or a Suica (registered trademark) cell phone.

  In such a mobile phone, billing settlement processing is also realized by one application software, and security is strictly managed. Since the fare billing and settlement application software always records ticket information when passing through the automatic ticket gate 25, the ticket information can be used later even if the navigation application is not activated at the time of recording. Is possible.

  FIG. 4 is an allocation diagram of a memory area of an application that uses a non-contact IC chip. In FIG. 4, applications A, B, and C are all applications for billing settlement processing, and among them, application C is a fare billing settlement application for public transportation. Each of the applications A, B, and C has an independent memory area for security, and in particular, it is a matter related to billing settlement, so that free memory access from other applications is prohibited.

  Information on the fare billing settlement application C cannot be referred to by other applications, but if the fare billing settlement application C provides the public area 12 in the memory area and writes the ticket gate information there, it can be referenced from other applications. It becomes possible.

  The station name, ticket gate passage time information, and the like may be disclosed because they do not directly cause problems such as security, and the navigation application can refer to this public area 12 to know the boarding station and ticket gate passage time. it can.

(Second method for obtaining ticket gate information)
As shown in FIG. 5, if the fare billing settlement application C writes the ticket gate information in the common area 13 different from the memory area dedicated to the application C, it can be referred from the navigation application. The common area 13 may be an internal memory area of the non-contact IC chip 4 or may be an external storage unit 6, for example.

(Third method for obtaining ticket gate information)
The first and second methods for obtaining ticket gate information described above are possible when the ticket gate information is written in the non-contact IC chip 4 or the like, and in the case of a portable mobile terminal device equipped with an IC tag that emits only ID information On the basis of the ID information received by the automatic ticket gate 25 from the portable mobile terminal device, the information remains only in the fare billing settlement server (not shown).

  In this case, as in the chart between the navigation server / fare billing server in the sequence chart shown in FIG. 6, an inquiry for ticket gate information is issued from the portable mobile terminal device to the navigation server, and it is used as a trigger, An inquiry for ticket gate information is made from the navigation server to the fare billing settlement server. As a response, ticket information is transmitted to the navigation server. Of course, since the operator of the fare billing settlement server and the operator of the navigation server are expected to be different, adjustments are made in advance so that the system is linked.

  Note that the ticket gate information includes information for specifying the location of the automatic ticket gate and time information of the automatic ticket gate 25 itself, in addition to information for specifying the station name and the ticket gate.

  Returning to the flowchart showing the processing procedure executed by the navigation application of FIG. If the ticket gate information is obtained by any of the above methods, the process jumps from step S101 in FIG. 3 to step S105, and if there is no ticket gate information, the process proceeds from step S101 to step S102.

  In step S102, acquisition of GPS information is attempted. If there is position information by GPS, the position information is passed to the navigation server as shown in the sequence chart of FIG. The navigation server 40 lists nearby station names from the received position information and returns them to the mobile mobile terminal device 1. As shown in FIG. 7, the mobile mobile terminal device 1 displays this station name list on the display unit 8, causes the user to select any station name (step S <b> 104), and proceeds to step S <b> 105 after selection. Note that the station name may be listed by area information of the communication network of the mobile mobile terminal device 1 instead of the GPS position information.

  If there is no GPS information, the process proceeds from step S102 to step S103, the station name input screen of FIG. 8 is displayed on the display unit 8, and the user is made to input the station name. For example, when the station name “Kanda” is input, the station name “Kanda” is transmitted to the navigation server 40, and the navigation server 40 searches for the corresponding station name, and the area where the station name “Kanda” exists. The list is returned to the mobile mobile terminal device 1, and the mobile mobile terminal device 1 displays this area list on the display unit 8 as shown in FIG. 9. When the user who has seen this display selects the corresponding area from the screen display, the process proceeds to step S105.

  When, for example, Kanda Station (Tokyo) is determined in any of Steps S101, S103, and S104 and the process proceeds to Step S105, the navigation server 40 displays a list of trains that may be boarded at that time as a portable mobile terminal device. 1, the mobile mobile terminal device 1 displays this train list on the display unit 8 as shown in FIG. 10.

  The train list displayed in step S105 is a train list based on the ticket gate information when the process proceeds from step S101 to step S105, and is based on the result of searching the timetable database from the actual boarding station and ticket gate passage time. On the other hand, the train list in the case of proceeding from step S103 or S104 to step S105 may be an intermediate station or a transfer station after boarding.

  In the latter case, the user of the portable mobile terminal device 1 identifies a train from the train list list as shown in FIG. 10 based on the departure time of the intermediate station and transfer station as the object. Of course, when the fare calculation is displayed for reference, the amount may not be correct from a station on the way.

  Further, when displaying a train, a display color that gives an image of a route may be used. For example, the Keihin Tohoku Line is light blue, the Yamanote Line is yellow-green, and the Chuo Line is orange.

  The train list to be displayed does not need to include trains before the ticket gate passing time, but if the ticket gate information is only station information, it is necessary to list the trains after the entrance time to the station. If it becomes clear, it is only necessary to list trains after the time considering the required time to the landing.

  Further, when a customer visits a store after passing through the ticket gate, the train may be on a train after the train listed in FIG. For this reason, when a user clicks the downward triangle displayed below the departure time, it is preferable to update the train list at the following time.

  When the train on which the user has boarded is selected from the train list shown in FIG. 10, the setting of “departure station” necessary for route search and “transportation” used is completed. Thereafter, a route search is performed starting from the train network using the train as a departure condition, and a search result that is practical as shown in FIG. 11 can be obtained.

  In the present embodiment, it is possible to use for purposes such as checking arrival time when the user is late on the originally scheduled train, or searching for another route to recover the delay, and convenience is improved.

  Next, another embodiment of the present invention will be described. In the above-described embodiment, the selection item “on board” is provided in the route search condition to enable route search from the train. However, in this embodiment, the user does not select “on board”. Will be able to search for routes from trains by automatically distinguishing them as follows.

  The freight charge settlement application software charges the minimum fare (advance) when passing through the automatic ticket gate on the entrance side, and settles when passing through the automatic ticket gate on the ticket exit side. Therefore, if you look at the final data of the ticket gate information, you can tell whether it is after entering or still on the transportation route.

  Therefore, as in the flowchart shown in FIG. 12, in the process of setting the departure place, first, the final ticket gate information is checked in step S201. If the final ticket gate information is entry (IN), the process proceeds from step S201 to step S203, and the train from the station is set as a departure condition. If the final ticket gate information is participation (OUT), the process proceeds from step S201 to step S202, and the conventional departure point input mode is set.

  When the route search is performed in this manner, a plurality of route search results are obtained (including the case of using the next train on the same route), in which the user is going to get on or get on You can see the trains that are on the road and see the details of the route to find out the arrival time. Furthermore, since the switching is automatically performed, the same navigation application can be used when using the train and at other times.

  According to the present invention, a portable navigation device that specifies a departure condition by a simple operation and gets a route search under an accurate condition after getting on a transportation facility such as a train that has a timetable, specifically, a cellular phone. Etc. can be provided.
