Next, route search / guidance processing in the navigation system having the above-described configuration will be described.
FIG. 4 is a flowchart showing a main flow of processing (navigation processing) performed by the navigation device 100 in route search / guidance processing by the navigation system.
[0035]
In the navigation process, the arithmetic processing unit 101 first performs a destination setting process as shown in FIG. 4 (step 11).
FIG. 5 is a flowchart showing the flow of the destination setting process. FIG. 6 shows a display screen displayed on the display unit 106 in the joint setting process. FIG. Following this, a display screen displayed on the display unit 106 is shown.
As shown in FIG. 5, in the destination setting process, the arithmetic processing unit 101 displays an input method selection screen on the display unit 106 (step 111). On this input method selection screen, as shown in FIG. 6A, a list of input methods is displayed. In the present embodiment, three input methods of “designation from 50-sound list”, “designation from genre list”, and “input telephone number” are displayed.
[0036]
And, among the input methods displayed on the display unit 106, the driver moves the cursor to the display of the desired input method using a joystick or key, and then presses the enter key, or inputs the input method by voice, etc. Selection of a destination input method is acquired by input from the input unit 105 (step 113).
[0037]
After acquiring the input method, a destination input screen corresponding to the input method is displayed to acquire the destination (step 115).
That is, when the input method is “designation from the 50-sound list” or “designation from the genre list”, as shown in FIG. After acquiring the first sound and genre selection, if the selected genre is composed of further subdivided genres, the subdivided genre is displayed and the selection of the genre is repeated. . Then, when there are no more subdivided genres in the selected genre, as shown in FIG. 6 (c), the names of the destinations classified within the selected genre are displayed, and cursor movement and voice input are performed. Select and get the destination. When “input telephone number” is selected as the selection method, a box for inputting a destination is displayed, a telephone number is acquired by input from a keyboard or voice input, and a destination information storage unit 1031 is obtained. The destination is acquired from the correspondence between the telephone number stored in the destination and the destination.
[0038]
When the destination is acquired, the arithmetic processing unit 101 checks whether or not the final destination is already set in a predetermined area of the RAM (step 117).
If the final destination is not set in the first destination setting of the navigation process (step 117; N), this destination is displayed on the display unit 106 as shown in FIG. The display unit 106 displays a confirmation as to whether the final destination is “destination” and the passing destination is “passing point”, and the confirmation is obtained by input from the input unit 105.
[0039]
When confirmation that the destination may be the final destination can be obtained, the final destination is set as the final destination (step 121), and the final destination is referenced with reference to the data stored in the destination information storage unit 1031. The genre of the ground is acquired (step 123). The final destination and its genre are stored in a predetermined area in the RAM, the destination setting process is terminated, and the process returns to the main routine.
When the final destination is not already stored in the predetermined area of the RAM (step 117; N) and confirmation that the destination is not the final destination is acquired, this destination is set as the passing destination ( In step 127), the passing destination is stored in a predetermined area of the RAM (step 129), and the genre of the final destination is acquired with reference to the data stored in the destination information storage unit 1031 (step 123). Then, the final destination and its genre are associated with each other and stored in a predetermined area of the RAM, and the process returns to step 111.
The case where the final destination is already set and stored in the RAM (step 117; Y), such as during route guidance, will be described later.
[0040]
When the destination setting process is completed, the arithmetic processing unit 101 acquires a priority order when searching for a recommended route (step 13). The route search condition is a priority in the case of selecting one route from a plurality of routes in searching for a recommended route. The priority order is obtained by selecting conditions such as “select a route that can be reached in a short time”, “do not use a highway”, and “specify a waypoint” on the display unit 106, and specify the priority. If there is no, search for the shortest route. In addition, when “specify a transit point” is selected, the transit point is acquired by the same input as the departure point.
[0041]
When the destination and priority are acquired, the arithmetic processing unit 101 transmits the data, the current position of the vehicle detected by the current position detection unit 104, and the ID determined for each navigation device 100 (route). Search request processing) (step 15). The information center 150 calculates a recommended route from the current position detection unit 104 to the destination according to the destination and priority based on the intersection data, node data, and road data in the search route information storage unit 1532 (route search processing). . The details of this route search are executed by, for example, the methods described in JP-A-1-173297, JP-A-1-173298, and other various known methods.
Then, the coordinate data of the intersection on the recommended route (passing intersection sequence data) is transmitted to the navigation device 100 as the recommended route data.
[0042]
The arithmetic processing unit 101 of the navigation device 100 receives the recommended route data (passing intersection sequence data), stores it in the travel route storage unit 1032 (step 17), and then starts route guidance processing (step 19). .
FIG. 8 is a diagram illustrating a display screen during the route guidance process.
In the route guidance, as shown in FIG. 8, the arithmetic processing unit 101 displays a map image M including the current location of the vehicle on the display unit 106 based on the map image data stored in the map information storage unit 1035. The searched route is displayed on the map image based on the received recommended route data (passing intersection sequence data), and further, the voice output unit 107 outputs the corresponding voice guidance when turning left or right at the intersection.
In addition, when a new destination is input, the display unit 106 together with the route guidance map image starts destination setting processing and displays a destination setting menu on the display unit 106. The destination key K is displayed, and the destination setting request is acquired, for example, by pressing the destination setting key K or requesting “destination setting” by voice.
Then, it waits for a destination setting request while performing route guidance (step 21).
[0043]
When there is a destination setting request (step 21), the process returns to step 11 to perform destination setting processing again to obtain a new destination. The destination setting process in this case is the same as that described above from step 111 to step 117.
Since the final destination is already stored in the predetermined area of the RAM (step 117; N), the arithmetic processing unit 101 acquires the corresponding genre from the data in the destination information storage unit 1031 for the new destination. (Step 131).
Then, it is checked whether the final destination genre already stored in the RAM is the same as the new destination genre (step 133). If the genre is the same (step 133; Y), the final destination is changed. If it is determined that the final destination should be set, an inquiry about confirmation is made and the result of confirmation is acquired by input to a display key or voice input (step 135).
[0044]
In this embodiment, a confirmation inquiry is displayed on the display unit 106 and a confirmation screen is displayed as to whether or not a new destination may be set as the final destination as shown in FIG. However, from the voice output unit 107, “Do you want to set it as the final destination (destination)?” Or “Do not go to XX (the destination of the already searched route)” ●● ( You may make a confirmation inquiry such as “Go to a newly acquired destination)?” Or a confirmation inquiry by both screen display and audio output.
In this embodiment, an answer key is displayed, and an answer is acquired when the driver presses the key. However, a key corresponding to Yes and No is set on the button of the remote controller, and this key is set. Or a voice response may be obtained.
[0045]
If confirmation that the final destination is acceptable is obtained (step 135; Y), the new destination is set as the final destination (step 137), and data in a predetermined area of the RAM is updated (step 139). ). When confirmation that it is not the final destination is obtained (step 135; N), the new destination is set as the passing destination (step 143), and the data in the predetermined area of the RAM is updated (step 145).
[0046]
If the genre of the final destination already stored in the RAM is different from the genre of the new destination (step 133; N), the final destination is not changed, but there is a high possibility of adding a passing destination. Then, it is confirmed whether or not a new destination can be set as a passing destination, and an answer is obtained (step 141). This confirmation is performed by displaying a confirmation screen on the display unit 106 as to whether or not the newly acquired destination can be set as a passing destination (route), or without displaying the confirmation screen or together with the confirmation screen. Confirm by voice output such as “Can I set it as a transit destination” or “Do you stop by ●●?” “Do you go to ○○ after stopping by ●●?” Also good.
[0047]
Then, when an answer key displayed on the screen, a remote controller button press, a voice answer is obtained, and confirmation that the passing destination is acceptable can be obtained by the answer (step 141; Y). Updates the data in a predetermined area of the RAM (step 145) using the new destination as the passing destination (step 143). When confirmation that it is not a passing destination is acquired, the new destination is set as the final destination (step 137), and data in a predetermined area of the RAM is updated (step 139). At this time, the genre of the final destination is also rewritten.
[0048]
After the new destination is stored in the RAM (steps 139 and 145), the destination setting process is terminated and the process returns to the main routine. Then, the processing after the priority order acquisition in step 13 is repeated. At this time, in step 15, a search condition with the new destination as the final destination or the passing destination is transmitted to the information center 150. In step 17, the new destination is set as the final destination or the destination from the information center 15. Receive passing intersection sequence data of recommended route as passing destination. In the route guidance from step 19, route guidance is performed for this new recommended route.
[0049]
When there is no destination setting request during route guidance (step 21; N), the arithmetic processing unit 101 determines whether the vehicle has arrived at the destination from the current position of the vehicle detected by the current position detection unit 104. If it is grasped (step 23) and it has not arrived at the destination (step 23; N), it is monitored whether there is a destination setting request while continuing route guidance (step 21). When it is determined that the vehicle has arrived at the destination (step 23; Y), the RAM is cleared and other termination processing is performed, and the navigation processing is terminated.
[0050]
As described above, in the present embodiment, when the destination setting process is performed during route guidance, the newly selected or input destination genre is compared with the already set final destination genre. . If these genres are the same, the new destination is likely to replace the final destination, so it is determined that the new destination is the final destination final destination. If the genre is not the same, the new destination is likely to have set a passing point, so the final destination that has already been set is not changed, and the new destination is changed to the passing destination (passing point). ).
Then, after the determination result of the final destination or the passing destination is displayed on the display unit 106 and confirmation is acquired, the passing intersection sequence data of the recommended route by the new destination is acquired from the information center 150, and the recommended route is obtained. Change route to provide route guidance.
Therefore, according to the present embodiment, just by inputting a new destination, it is automatically determined whether this destination is the final destination or the passing destination, and the passing destination or the passing destination There is no need to input a certain instruction.
According to the present embodiment, whether the new destination is the final destination or the passing destination is determined based on the new destination and the genre of the final destination already set. For this determination, since data used in the destination acquisition process and stored in the destination information storage unit 1031 can be used, the amount of data for determination does not increase so much.
[0051]
Next, a second embodiment of the navigation device of the present invention will be described. The navigation apparatus according to this embodiment constitutes a navigation system together with the information center 150 similar to that of the first embodiment described above.
In the present embodiment, the same reference numerals are assigned to the same processing units as those in the first embodiment shown in FIGS. 1 to 8, and the description thereof is omitted.
[0052]
In the navigation device of the present embodiment, the storage unit 103 stores a genre determination information storage unit 1034 as correspondence storage means (described in FIG. 1).
[0053]
FIG. 9 is a conceptual diagram showing the contents of data stored in the genre determination information storage unit 1034.
As shown in FIG. 9, in the present embodiment, the genre determination information storage unit 1034 stores a correspondence table in which the destination genres stored in the destination information storage unit 1031 are associated.
Therefore, for example, the destination “green golf course” has a genre of golf course from the destination information shown in FIG. 2, and is determined as the final destination from the correspondence table shown in FIG. 9.
When determining a destination that is actually newly acquired, the calculation processing unit 101 determines whether the newly acquired destination and the destination of the recommended route already searched (whether the genre is the same). ).
[0054]
Except that the genre determination information storage unit 1034 is provided in the storage unit 103, it is the same as the above-described first embodiment.
[0055]
In the present embodiment, the destination acquisition process is performed as follows.
FIG. 10 is a flowchart showing the flow of destination acquisition processing in the present embodiment. In this figure, the same step number is assigned to the same process as the destination acquisition process of the first embodiment shown in FIG. 5, and the description thereof is omitted.
As shown in FIG. 10, in this embodiment, after the destination is acquired (step 115), if the final destination is not stored in the predetermined area of the RAM (step 117; N), The processing is the same as in the first embodiment described above.
A destination is acquired (step 15), and if the final destination is stored in a predetermined area of the RAM (step 117; Y), a new destination genre is acquired (step 131). As the genre of the new destination, the corresponding genre is acquired from the data in the destination information storage unit 1031.
[0056]
Then, it is examined from the correspondence table stored in the genre determination information storage unit 1034 whether the final destination corresponds to the genre of the destination (step 221). In the correspondence table, if the final destination corresponds (step 221; Y), it is likely that the new destination is the final destination, and the new destination is newly set as in step 135 of the first embodiment. In the first embodiment described above, confirmation is made as to whether a final destination may be set as the final destination, and the result of the confirmation is acquired by input to a display key or voice input. The same processing is performed.
[0057]
If the passing destination corresponds in the correspondence table (step 221; N), the final destination genre stored in the RAM is acquired (step 223), and the final destination genre and the new destination genre are acquired. It is checked whether or not the genre is the same (step 225). If the final destination genre and the new destination genre are the same (step 225; Y), the new destination is likely to be the final destination regardless of the correspondence in the correspondence table. As in step 135 of the first embodiment, confirmation is made as to whether a new destination may be set as the final destination, the result of the confirmation is obtained by input to a display key or voice input, and thereafter destination setting is performed. The same processing as in the first embodiment is performed until the processing is completed.
If the genre of the final destination stored in the RAM is different from the genre of the new destination (step 225; N), the new destination is likely to be a passing destination as shown in the correspondence table. As in step 141 of the first embodiment, confirmation is made as to whether a new destination may be set as the passing destination, and the result of confirmation is obtained by input to a display key or voice input. Processing similar to that in the first embodiment is performed until the end of the ground setting processing.
[0058]
As described above, also according to the present embodiment, simply by inputting a new destination, it is automatically determined whether the destination is the final destination or the passing destination. There is no need to input an instruction such as being on the ground.
[0059]
In addition, the vehicle control apparatus of this invention is not limited to the above-mentioned embodiment, Unless it deviates from the meaning of this invention, it can change suitably.
For example, in the above-described embodiment, the genre that classifies the destination is used to display the destination candidates in the destination setting process, and this genre is used as the attribute classification. However, the present invention is not limited to this. Instead, the genre of the destination may be further finely divided, or a group of several genres may be grouped together and stored as attribute divisions in the determination information storage means and used.
In the above-described embodiment, the destination is acquired again in a state where the recommended route is set, and the search request for the recommended route according to this destination is performed after acquiring the priority again. The priority may be the same as the previous recommended route search request without obtaining.
In addition, after the destination is determined, a route search request is made before confirmation is obtained, and if the confirmation is OK, the route search result may be used immediately to guide the route. .
The car navigation device of the present embodiment constitutes a car navigation system together with an information center. However, the car navigation system includes a route search information storage unit that stores data for route search, and is used for route search request processing and reception of recommended route data. Alternatively, the route search process may be performed in the car navigation device.
[0060]
The above-mentioned change is not limited to one, and a plurality of these can be selected and adopted as appropriate.
[0061]
【The invention's effect】
As described above, according to the present invention, when a new destination is acquired, whether the new destination is the final destination or the passing destination. Based on attribute classification Therefore, it is possible to easily change the final destination and add the passing destination.
