In this case, such a program may be provided to the CPU circuit via a recording medium or an appropriate communication path.

Next, as shown in FIG. 2a, the map database 16 stores map data representing a map, address data, and facility data.
In the address data, correspondence between addresses and coordinates in each place is registered.
The facility data includes facility records provided for each facility. Each facility record includes a facility identifier uniquely assigned to the facility, a facility type indicating the type of restaurant, SA (service area), tourist facility, park, etc., a facility name that is the name of the facility, a facility The facility coordinates representing the latitude and longitude coordinates of the facility, the facility address representing the address of the facility, the telephone number of the facility, and the facility detailed description which is various information relating to other facilities are stored.

Next, the SNS server 3 and the point server 4 will be described.
As shown in FIG. 3, the SNS server 3 includes a posted article database 31 and an SNS providing unit 32.
The posted article database 31 stores post data for each account provided for each SNS account. In the post data by account, each post posted to the SNS server 3 from the corresponding account using a mobile phone, a smartphone, a personal computer, or the SNS client of the in-vehicle system 1 is stored as post article data. ing.

In addition to the posted article itself, each posted article data includes the posted date and time of the posted article, and posted coordinates that are the coordinates at which the contributor (device on which the SNS client is mounted) was located at the time of posting.
Next, the SNS providing unit 32 accepts a posted article posted to the SNS server 3 using an SNS client from an SNS account, and corresponds to the account that posted the posted article in the posted article database 31 as posted article data. Store in separate posted article data.
In addition, the SNS providing unit 32 generates timeline data including, for each SNS client, each posted article posted by the account of the SNS client together with information on the account that posted the posted article, the posting date and time, and the posting coordinates. Or post to each SNS client each posted article posted by the account of the SNS client and other accounts that the account has registered to follow, information on the account that posted the posted article, posting date and time, etc. Generate and distribute timeline data including coordinates.

Next, the point server 4 includes a user-specific point database 41, a data collecting unit 42, and a data providing unit 43.
The user-specific point database 41 stores user-specific point data provided for each user of the point server 4. Here, the user of the in-vehicle system 1 corresponds to the user of the point server 4.
The user-specific point data includes a corresponding user's SNS account and a point table, and a name and coordinates can be registered in each entry (each row in the figure) of the point table.
Next, the data collection unit 42 functions as an SNS client with respect to the SNS server 3 and periodically performs the following processing for each user corresponding to each user-specific spot data registered in the user-specific spot data.
That is, the SNS server 3 is accessed with an account registered in the user-specific spot data corresponding to the user, and the timeline data of the account is acquired from the SNS server 3.
Then, for each posted article included in the timeline data, a phrase representing the facility name included in the posted article is extracted, and the extracted phrase and the posted coordinates of the posted article are used as an extracted name and an extracted coordinate.
That is, for example, if the posted article is “arrival at the first building, XX meeting now” and the posted coordinates of the posted article are (X ## 1, Y ## 1), the facility name is represented in the posted article The phrase “first building” is the extracted name, and the post coordinates (X ## 1, Y ## 1) are the extracted coordinates.
Here, the phrase representing the facility name in the posted article can be extracted by syntactic / semantic analysis of the posted article. Alternatively, a facility name database that stores facility names is provided in the point server 4, and a phrase that matches the facility name registered in the facility name database with a predetermined level or more among the phrases included in the posted article represents the facility name. By doing so, it is possible to extract a phrase representing the facility name from the posted article.

  Then, the extracted name and the extracted coordinates are registered in the newly created entry in the point table of the user-specific point data corresponding to the user as the name and coordinates. However, if an entry in which a name / coordinate pair that matches the extracted name / extracted coordinate pair is already registered in the location table, a new entry is not created and registered in the entry. .

  And the data provision part 43 corresponds to the search name of the point table of the point data according to user corresponding to the user who issued the search request in response to the search request specifying the search name from the user of the in-vehicle system 1. The entry in the point table where the name is registered is searched, and the coordinates registered in the searched entry are returned to the in-vehicle system 1.

  Now, returning to FIG. 1, the calendar client 20 of the in-vehicle system 1 stores the calendar in which the user's schedule of the in-vehicle system 1 stored in the memory 21 is stored in the calendar server 5. Synchronize with the user's calendar, display the calendar stored in the memory 21 on the display device 12 via the GUI control unit 23, and edit the schedule to be registered in the displayed calendar according to the operation of the input device 11. Perform processing.

Next, the navigation unit 19 of the in-vehicle system 1 calculates the current position by map matching processing between the output of the vehicle state sensor 14 or the GPS receiver 15 and map data.
In addition, the navigation unit 19 searches for and sets a guidance route to the destination set by the control unit 22 based on the map data stored in the map data storage unit, and guides the guidance route when the destination arrives. Also cancel settings.
Further, the navigation unit 19 generates a guide image in which a graphic representing the current position, the set guidance route and the destination is drawn on the map image indicating the map represented by the map data in the map database 16, and the GUI control unit For example, a process of displaying on the display device 12 via the display 23 is performed.
Hereinafter, the destination setting process performed by the control unit 22 for setting the destination in such a configuration will be described.
FIG. 4 shows the procedure of the destination setting process.
The destination setting process is a process that is performed when the user instructs the start of the destination setting process via the input device 11. As shown in FIG. The desired facility is set as the destination name (step 402).

  Here, the setting of the destination name in step 402 may be performed by setting the name of the facility as the destination name for the character string input using the input device 11, An input device may be provided, and a character string obtained by recognizing the voice spoken by the user may be set as a destination name, or the calendar client 20 may be registered in the calendar stored in the memory 21. Alternatively, a character string representing the first visited place after the current date and time registered in a certain schedule may be set as the destination name.

  Next, when the destination name is set in this way, the facility data in the map database 16 is searched using the destination name as a search key, and the facility name that matches or partially matches the destination name is registered. Existing facility records are extracted from the map database 16 (step 404).

Further, it is checked whether or not the number of search hits, that is, the number of facility records extracted by the search is 0 (step 406).
If the number of hits in the search is not 0, the priority order of the facility records searched in step 404 is higher as the distance from the current position to the position represented by the facility coordinates of each facility record is lower. (Step 408).
Then, it is checked whether or not the number of hits in the search is greater than a predetermined threshold Th (for example, Th = 10) (step 410). If not, the process proceeds to step 416.
On the other hand, if the number of facility records searched in step 404 is greater than the predetermined threshold Th (step 410), a search request specifying the destination name as the search name is issued to the point server 4 to From the server 4, the coordinates registered in the entry of the point table in which the name that matches the destination name is registered among the points in the point table of the point data by user corresponding to the user of the in-vehicle system 1. (Step 412).

  Then, the priority order of each facility record set in step 408 is raised to the highest priority order of the facility record in which the facility coordinates that can be regarded as coincident with the coordinates obtained from the point server 4 are registered ( The process proceeds to step 414) and step 416. In addition, when the facility record searched in step 404 includes a plurality of facility records in which facility coordinates that can be considered to coincide with the coordinates acquired from the point server 4 are included, the priority order between the included facility records is as follows. The smaller the distance from the current position to the position represented by the facility coordinates of each facility record, the higher the setting.

When the process proceeds to step 416, a list in which the combination of the facility name and the facility address of the facility record searched in step 404 is arranged from the top according to the priority order of the facility record is displayed on the display device 12 as a destination candidate list. To do.
If the user performs an operation of selecting a facility as a destination on the destination candidate list (step 418), the coordinates of the selected facility (here, the facility in the facility record of the selected facility) (Coordinates) is set as the destination (step 420), and the destination setting process is terminated.
Next, when it is determined in step 406 that the number of hits for the search is 0, by issuing a search request designating the destination name as the search name to the point server 4, the point server 4 The coordinates registered in the entry of the point table in which the name that matches the destination name among the points in the point table of the user-specific point data corresponding to the user of the in-vehicle system 1 are acquired (step 422). .

  Then, the acquired coordinates are converted into addresses using the address data of the map database 16, the destination name is the facility name, the converted address is the facility address, and a list of pairs of the facility name and address is the destination candidate list. Is displayed on the display device 12 (step 424). In this case, if there are multiple pairs of facility names and addresses to be included in the list, that is, if there are multiple coordinates acquired from the point database, there are more pairs that include addresses corresponding to coordinates closer to the current location. A destination candidate list is generated so as to be arranged above.

If the user selects a facility as a destination on the destination candidate list (step 418), it corresponds to the coordinates of the selected facility (here, the facility address of the selected facility). The coordinates acquired in step 422) are set as the destination (step 420), and the destination setting process is terminated.
The destination setting process has been described above.
An example of such destination setting processing will be described below.
Here, it is assumed that the name of the facility desired to be the destination designated by the user is “first building”, and the “first building” is set as the destination name.
In addition, the user of the in-vehicle system 1 coordinates to the SNS server 3 a post article “Arrive at the first building, XX meeting” from the facility that the user called “the first building” in the past (X ## Assume that you are posting from 1, Y ## 1). Here, in this case, the posted coordinates of the posted article are (X ## 1, Y ## 1), and the user corresponding to the user of the in-vehicle system 1 is processed by the data collection unit 42 of the point server 4 described above. In the point table of the different point data, there are entries in which “first building” and (X ## 1, Y ## 1) are registered as a set of name and coordinates.

  In this case, when the number of facility records obtained by searching the map data in the map database 16 using the destination name “first building” as a search key is 1 or more and a predetermined threshold value Th or less. 5a displays on the display device 12 a candidate destination list 510 in which the facility name and facility address pairs of each facility record retrieved from the facility data are arranged from the top to the bottom near the current position. Is done.

  On the other hand, if the number of facility records obtained by searching the map data in the map database 16 using the destination name “first building” as a search key exceeds a predetermined threshold Th, the destination By issuing a search request designating the name “first building” as a search name to the location server 4, from the location server 4, among the entries in the location table of user-specific location data corresponding to the user of the in-vehicle system 1 The coordinates (X ## 1, Y ## 1) registered in the entry of the location table in which the name that matches the search name “first building” is registered are acquired.

  Here, in the facility record obtained by searching the map data in the map database 16, there is a facility record in which the facility coordinates approximately matching the acquired coordinates (X ## 1, Y ## 1) are registered. It is assumed that the facility name of this facility record is “ALP first building” and the facility address is (XX city XX town XX town 123).

  In this case, the priority order of the facility record of the facility name “ALP first building” is set to the top. Further, as shown in FIG. 5b, a form in which the set of the facility name “ALP first building” and the facility address (XX city XX town 123 in XX prefecture) of the facility record with the highest priority is arranged at the top is provided. Then, the destination candidate list 510 in which the combination of the facility name and facility address of each facility record obtained by searching the map data using the destination name “first building” as a search key is displayed on the display device 12. It will be.

  As a result, even when the user designates the name of the facility as the facility that the user wants to call with the ambiguous name that the user is used to, the ambiguous name is included in the article by the user including the ambiguous name in the past. From the posted article posted from the facility that the user is calling in, the facility specified by the ambiguous name is estimated, and a destination candidate list 510 arranged at a higher level so that the estimated facility can be easily selected as the destination is displayed. Can be displayed.

  If the destination candidate list 510 is displayed as shown in FIGS. 5a and 5b, the facility selection is accepted from the user on the destination candidate list 510 as shown in FIG. 5c, and the “set to destination” button 520 is displayed. If is operated, the facility coordinates of the facility currently selected are set as the destination.

  Next, when the destination name “first building” is used as a search key and the number of facility records obtained by searching the map data in the map database 16 is 0, the destination name “first building” is used. By issuing a search request designated as a search name to the location server 4, the search name “first building” in the location table entry of the user-specific location data corresponding to the user of the in-vehicle system 1 from the location server 4. The coordinates (X ## 1, Y ## 1) registered in the entry of the point table in which the name matching “” is registered.

  Then, referring to the address database, the coordinates (X ## 1, Y ## 1) are converted into an address (XX city XX city XX town 123), and as shown in FIG. 5d, the destination name “first building” And the converted address (XX city XX city XX town 123) as a facility address, a list of pairs of facility names and addresses is displayed on the display device 12 as a destination candidate list 510. In this case, since the facility at the displayed address may not match or partially match the destination name specified by the user, a description such as “Is this facility?” Should be included. The validity of the address displayed on the user himself as the destination of the facility is prompted.

  If the “set to destination” button 520 is operated, the coordinates converted into the address of the facility currently selected are set as the destination. However, in the example shown in FIG. 5d, since only one facility is included in the destination candidate list 510, the one facility is unconditionally handled as the selected facility.

As a result, when the facility corresponding to the ambiguous name designated by the user cannot be searched from the facility data, the user calls the user with the ambiguous name by including the ambiguous name in the past in the article. When there is a posted article posted from a certain facility, the user can set the coordinates of the facility designated by the ambiguous name as the destination.
The embodiment of the present invention has been described above.
By the way, step 412 of the destination setting process of the above embodiment is a process of acquiring all coordinates registered in the point table of the user-specific point data corresponding to the user of the in-vehicle system 1 from the point server 4. Also good.
Here, when there are a plurality of facilities searched from the facility data with the name specified by the user, the facility that the user has visited among the plurality of facilities may be the facility specified by the user Is considered high. Therefore, if the facility that the user has visited is obtained from the posting coordinates of the posted article posted by the user and the destination candidate list 510 in which the obtained facility is arranged is displayed, the user can It is possible to increase the probability that the intended facility can be easily selected as the destination.

  In addition, the processing part of the destination setting processing steps 402-416 and 422-424 in the above embodiment is applied to an arbitrary process for receiving a facility with the name of the facility from the user and specifying the facility represented by the name. Can do. That is, for example, in the case of applying to the process of representing on the map the location of the facility that matches the name specified by the user, the facility selection operation is accepted on the destination candidate list displayed in step 416 or 424 and selected. A map around the operated facility may be displayed together with a mark representing the selected facility location on the map.

  In the above embodiment, the point server 4 uses the posting coordinates of the posted articles of the SNS server to estimate the facility corresponding to the destination name designated by each user, but this is replaced with the SNS server. Alternatively, a photo library on the interface network in which photo data with titles and shooting position information taken by each user is stored may be used.

  That is, in this case, the point server 4 uses the titles of the photos and the shooting position information stored in the photo library instead of the posted articles and the posted coordinates of the SNS server 3, and the point table of each user's point data for each user. Should be created.

  Moreover, you may make it provide the function of the point server 4 in the above embodiment in each vehicle-mounted system 1. However, in this case, each in-vehicle system 1 acquires the timeline data of the account from the SNS server 3 only for the SNS account of the user of the in-vehicle system, and stores it in the point table of the point data for each user of the account. Performs processing to register names and coordinates.
