JP2013-002897A

However, there is a problem that an appropriate arrival point cannot be set if a point where at least one item of the name, address, and telephone number matches the destination point is not defined in the guidance server database. . In Patent Document 1, since a point on the road closest to the destination point searched in the database managed by the search provider is set as the arrival point, a point that is not suitable for arrival of the vehicle is set. was there.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique that can acquire an entrance of a facility intended by a user as a destination.

  In order to achieve the above object, a destination acquisition system of the present invention is a database on the Internet managed by a search provider, and is a facility searched in a search database that records at least the coordinates of the facility for each facility. The search facility acquisition unit for acquiring a search facility, and the vehicle database in which the site area of the facility and the entrance where the vehicle can enter the site area are associated and recorded for each facility, the coordinates of the search facility are And a destination acquisition unit that acquires an entrance associated with the corresponding facility as a destination when a corresponding facility that is a facility existing in the site area can be searched.

  In order to achieve the above object, a destination acquisition method of the present invention is a database on the Internet managed by a search provider, and is a facility searched in a search database that records at least the coordinates of the facility for each facility. The search facility acquisition step for acquiring a search facility, and the vehicle database in which the site area of the facility and the entrance where the vehicle can enter the site area are recorded in association with each facility, the coordinates of the search facility are A destination acquisition step of acquiring, as a destination, an entrance associated with the corresponding facility when a corresponding facility that is a facility existing in the site area can be searched.

  In order to achieve the above object, a destination acquisition program according to the present invention is a database on the Internet managed by a search provider, and is a facility searched in a search database in which at least the coordinates of the facility are recorded for each facility. The search facility acquisition function for acquiring a search facility, and the vehicle database in which the site area of the facility and the entrance where the vehicle can enter the site area are recorded in association with each facility, the coordinates of the search facility are When a corresponding facility, which is a facility existing in the site area, can be searched, a computer is realized with a destination acquisition function for acquiring the entrance associated with the corresponding facility as a destination.

  With the above configuration, it is possible to search for a corresponding facility in which the coordinates of the search facility searched in the search database exist within the site area, and to search for a facility intended by the user as the corresponding facility. If the coordinates of the search facility specified in the search database are within the site area of the corresponding facility specified in the vehicle database, it can be estimated that the corresponding facility is a facility that the user intends to search. Furthermore, since an entrance through which a vehicle can enter the site area of the corresponding facility can be acquired as a destination, a point suitable for arrival can be acquired as a destination.

It is a block diagram which shows a destination acquisition system. (2A) and (2B) are diagrams showing site areas. It is a flowchart of the destination acquisition process.

Here, embodiments of the present invention will be described in the following order.
(1) Configuration of destination acquisition system:
(2) Destination acquisition processing:
(3) Other embodiments:

(1) Configuration of destination acquisition system:
FIG. 1 is a block diagram showing a configuration of an in-vehicle device 10 as a destination acquisition system according to the present embodiment. The vehicle-mounted device 10 is a navigation device mounted on a vehicle, and is configured to be able to communicate with a smartphone 30 carried by a user. The smartphone 30 is configured to be able to communicate with the search server 20 on the Internet. The search server 20 is a server managed by a search provider.

  The vehicle-mounted device 10 and the search server 20 include control units 11 and 21, communication units 12 and 22, and recording media 13 and 23, respectively. Each of the control units 11 and 21 includes a CPU, a ROM, and a RAM (not shown), and develops program data recorded in the ROM and the recording media 13 and 23 on the RAM and executes various programs. The communication unit 12 of the in-vehicle device 10 and the smartphone 30 realize bidirectional communication by short-range wireless communication or wired communication.

  Next, the software configuration of the program executed by the control unit 21 of the search server 20 will be described. As shown in FIG. 1, the control unit 21 of the search server 20 executes a search program 210 including a search facility transmission module 210a. The search program 210 acquires a destination search condition from the smartphone 30 via the communication unit 22 and searches a search DB (Database) 23a for a search facility that is a facility that matches the search condition. The search condition is a condition specified by the user in the smartphone 30, and may be a single or a plurality of search keywords, or a search range may be imposed on facility attributes, regions, and the like. The search condition may be specified on a map application or browser executed by the smartphone 30, for example.

  The search DB 23a is a database that records general facility information in association with each facility. The general facility information includes keyword information indicating a name, address, telephone number, facility attribute (genre), and the like, and coordinate information indicating the coordinates of the facility. The search server 20 circulates on the Internet and collects general facility information, for example, by executing a crawler. In the search DB 23a, general facility information registered by general users is also accumulated. A user who uses a mobile terminal with a GPS function such as the smartphone 30 transmits post information in which a description of the current position is associated with coordinates detected by the mobile terminal to the search server 20 or another server on the Internet. Then, the search server 20 collects post information and stores it in the search DB 23a as general facility information.

  With the function of the search facility transmission module 210a, the control unit 21 searches the search DB 23a for a facility that best matches the search condition, and transmits search facility information that is general facility information indicating the search facility that is the searched facility to the smartphone 30. To do. The control unit 21 may search for a facility using a publicly-known search method, and selects a facility having the highest popularity (selection frequency) or a facility having the highest freshness and reliability of information from facilities that match the search conditions. You may search as. Matching the search condition may be, for example, that the search keyword specified by the user is associated with keyword information that partially or partially matches. The smartphone 30 that has received the search facility information transmits the search facility information to the vehicle-mounted device 10.

  Next, the software configuration of the program executed by the control unit 11 of the vehicle-mounted device 10 will be described. As shown in FIG. 1, the control unit 11 of the vehicle-mounted device 10 executes a destination acquisition program 110. The destination acquisition program 110 includes a search facility acquisition module 110a, a destination acquisition module 110b, and a route guidance module 110c.

  The search facility acquisition module 110a is a database on the Internet managed by a search provider, and has a function of acquiring a search facility that is a facility searched in the search DB 23a that records at least the coordinates of the facility for each facility. 11 is executed. That is, when the search facility information is received from the smartphone 30, the control unit 21 acquires the search facility indicated by the search facility information by the function of the search facility acquisition module 110a.

  The destination acquisition module 110b uses the vehicle DB (Database) 13a in which the site area of the facility and the entrance where the vehicle can enter the site area are recorded in association with each facility, and the coordinates of the search facility are the site. When a corresponding facility that is a facility existing in the area can be searched, the control unit 11 is caused to execute a function of acquiring the entrance associated with the corresponding facility as a destination. The vehicle DB 13a is recorded in the recording medium 13 of the vehicle-mounted device 10, and is a database in which vehicle facility information is accumulated for each facility. Vehicle facility information is the most representative of the site information that is the polygon of the site area where the facility is located, the internal area information that is the polygon of the internal area existing in the site area, and the entrance through which the vehicle can enter the site area. Representative entrance information indicating a typical entrance, optimum entrance information indicating the best entrance to the facility among the entrances where vehicles can enter the site area, name, address, telephone number, facility attribute (genre), etc. Including keyword information. In the vehicle DB 13a, an optimum entrance is recorded in association with each of a plurality of internal areas in the site area. The keyword information may be recorded for each internal area.

表１は、敷地領域Ｒに対応する対応施設の車両用施設情報を示す表である。内部領域Ａ〜Ｃは、それぞれ敷地領域Ｒ内において建設された建物が占める領域である。このように、内部領域Ａ〜Ｃに対応する各建物が存在する敷地領域Ｒが共通することが有り得る。例えば、テナントごとに建設された建物が共通の敷地内に存在している複合商業施設においては、共通の敷地領域Ｒ内に複数の内部領域Ａ〜Ｃが存在し得る。敷地領域Ｒのうち、内部領域Ａ〜Ｃ以外の領域は、各テナントの共用スペースであり、例えば共用の駐車場や休憩場であってもよい。内部領域Ａ〜Ｃは必ずしも独立した建物でなくてもよく、共通の建物内において各テナントが使用権を有する店舗区画であってもよい。 2A and 2B are schematic views for explaining a site area and an internal area. 2A and 2B, three internal areas A to C exist in the site area R of the complex commercial facility whose facility name is “XYZ Mall”.

Table 1 is a table showing the vehicle facility information of the corresponding facility corresponding to the site area R. Each of the internal areas A to C is an area occupied by a building constructed in the site area R. Thus, the site area R where the buildings corresponding to the internal areas A to C exist may be common. For example, in a complex commercial facility where a building constructed for each tenant exists in a common site, a plurality of internal regions A to C may exist in the common site region R. Of the site area R, the area other than the internal areas A to C is a shared space of each tenant, and may be, for example, a shared parking lot or a rest area. The internal areas A to C are not necessarily independent buildings, and may be store sections where each tenant has a right to use in a common building.

  As shown in FIGS. 2A and 2B, there are three entrances G1 to G3 in the site area R, and the three entrances G1 to G3 are recorded in association with the site area R in the vehicle facility information. Among these, the entrance G2 is recorded in association with the site area R as a representative entrance which is the most representative entrance. In the present embodiment, the representative entrance is an entrance that is determined to be representative by an investigator who conducts a survey for creating vehicle facility information. Further, in each of the internal areas A to C, the optimum entrances that are the optimum entrances G1 to G3 are recorded in association with each other. As shown in Table 1, the entrance G1 is associated as the optimum entrance for the internal region A, the entrance G2 is associated as the optimum entrance for the internal region B, and the entrance G3 is associated as the optimum entrance for the internal region C. It has been. In the present embodiment, the entrances G1 to G3 having the shortest distances from the internal regions A to C are associated with the optimum entrances.

  When the function of the destination acquisition module 110b allows the control unit 21 to search for a corresponding facility whose facilities are within the site area R, the control unit 21 uses the entrance associated with the corresponding facility as the destination. get. That is, the control unit 21 acquires the coordinate SP of the search facility indicated by the search facility information, and searches for a corresponding facility where the coordinate SP exists in the site area R. And control part 21 acquires either of entrance G1-G3 matched with corresponding facilities as destination DP.

  More specifically, by the function of the destination acquisition module 110b, the control unit 21 acquires the entrances G1 to G3 associated with the internal areas A to C where the coordinates SP of the search facility exist as destinations. For example, as shown in FIG. 2A, it is assumed that a coordinate SP exists in the internal region C. In this case, the control unit 21 acquires the entrance G3, which is the optimum entrance associated with the internal area C, as the destination DP. For example, when the user searches the destination by specifying the name of the internal region C as a search keyword on the smartphone 30, the search facility coordinates SP whose name is the name of the internal region C may be obtained from the search DB 23a. large. In the vehicle DB 13a, the corresponding facility corresponding to the site area R where the coordinate SP exists is searched, and among the internal areas A to C of the corresponding facility, the optimum entrance corresponding to the internal area C where the coordinate SP exists is searched. A certain entrance G3 is acquired as the destination DP.

  On the other hand, by the function of the destination acquisition module 110b, the control unit 21 allows a plurality of entrances existing in the site area R when the coordinates SP of the search facility do not exist in any of the internal areas A to C in the site area R. The most representative entrance G2 among G1 to G3 is acquired as the destination DP. As shown in FIG. 2B, when the coordinates SP of the search facility exist in the site area R, but do not exist in any of the internal areas A to C in the site area R, a plurality of existing in the site area R Of the entrances G1 to G3, the most representative entrance G2 is acquired as the destination DP.

  The route guidance module 110c causes the control unit 11 to perform a function of guiding a scheduled travel route from the departure point to the destination DP. That is, by the function of the route guidance module 110c, the control unit 21 searches for a planned travel route connecting from the departure point to the destination DP by a known route search method, and guides the vehicle to travel on the planned travel route. Is performed by the user I / F unit 14. The control unit 21 acquires, for example, the current position of the vehicle specified based on an output signal from the position sensor 15 as a starting point, and an optimal planned travel route connecting the starting point to the destination DP based on the map information 13b. Explore. As the position sensor 15, a GPS receiver, a vehicle speed sensor, a gyro sensor, or the like may be provided. In the map information 13b, the position and shape of a road section obtained by dividing a road on which a vehicle can travel for each intersection are recorded. The intersection is a point where two or more road sections are connected, and entrances G1 to G3 of the site area R are also included in the intersection. The user I / F unit 14 is, for example, a touch panel display, and serves as both an input device that receives a user operation and an output device that outputs an image of guidance on a scheduled travel route. For example, when the current position of the vehicle approaches within a predetermined distance (for example, 30 m) from the destination DP, the control unit 21 guides that the vehicle has arrived around the destination DP and travels the planned travel route. End the guidance.

  In the configuration of the present embodiment described above, when a corresponding facility that is a facility where the coordinate SP of the search facility exists in the site area R can be searched in the vehicle DB 13a, the entrance associated with the corresponding facility. G1 to G3 are acquired as the destination DP. Thereby, the corresponding facility where the coordinates SP of the search facility searched in the search DB 23a exist in the site area R can be searched, and the facility intended by the user can be searched as the corresponding facility. Furthermore, since the entrances G1 to G3 through which the vehicle can enter the site area R of the search facility can be acquired as the destination DP, a point suitable for arrival can be acquired as the destination DP.

  Furthermore, since the control unit 21 acquires the entrances G1 to G3 associated with the internal areas A to C where the coordinates SP of the search facility exist as destinations, a plurality of internal areas A to C are thereby defined. In addition, even when there are a plurality of entrances G1 to G3 to the site area R, the optimum entrances G1 to G3 for the internal areas A to C intended by the user can be acquired as the destination DP. That is, if the search facility coordinates SP that match the search conditions specified by the user are present in any of the plurality of internal areas A to C within the common site area R, the search facility coordinates SP are The entrances G1 to G3 associated with the existing internal areas A to C can be acquired as the destination DP.

  Furthermore, the control unit 21 is the most representative of the plurality of entrances G1 to G3 existing in the site area R when the coordinates SP of the search facility do not exist in any of the internal areas A to C in the site area R. An entrance G2 is acquired as the destination DP. Thus, when there are a plurality of internal areas A to C in the site area R but it is not clear which internal area A to C the user is going to go to, the most representative entrance G2 is set as the destination. Obtained as DP. By setting the most representative entrance G2 as the destination DP, it is possible to prevent an entrance that gives a sense of discomfort to the user from becoming the destination DP.

(2) Destination acquisition processing:
FIG. 2 is a flowchart of the destination acquisition process executed by the vehicle-mounted device 10. The destination acquisition process is a process executed when the smartphone 30 transmits the search facility information to the vehicle-mounted device 10 in a state where the search of the search facility is completed between the smartphone 30 and the search server 20 in advance. is there. First, the control part 21 receives search facility information from the smart phone 30 by the function of the search facility acquisition module 110a (step S100). That is, the control unit 21 acquires the search facility indicated by the search facility information indicated by the search facility information by the function of the search facility acquisition module 110a.

  Next, by the function of the search facility acquisition module 110a, the control unit 21 determines whether a similar facility whose keyword information is similar to that of the search facility can be searched (step S110). The keyword information is information indicating the name, address, telephone number, and facility attribute (genre) of the facility. The control unit 21 searches the vehicle DB 13a for a similar facility that is associated with keyword information whose similarity with the keyword information of the search facility acquired from the smartphone 30 is greater than or equal to a threshold value. For example, the number of matching items in the keyword information may be greater than or equal to the threshold. Matching keyword information may mean that the character strings representing the keyword information all match, or may partially match (forward match, backward match, etc.).

  If it is determined that a similar facility with similar keyword information to the search facility can be searched (step S110: Y), the control unit 21 uses the function of the destination acquisition module 110b to control the inter-facility distance that is the distance between the search facility and the similar facility. Is within a predetermined distance (for example, 500 m) (step S120). That is, the control unit 21 determines whether the distance between the coordinate SP of the search facility and the site area R of the similar facility is within a predetermined distance. The inter-facility distance may be the shortest distance from the coordinate SP to the site area R, or may be the distance from the coordinate SP to the center of gravity of the site area R. Further, the coordinates of the site area R may be defined in the vehicle DB 13a, and the inter-facility distance may be a distance between the coordinates SP of the search facility and the coordinates of the site area R of the similar facility.

  When it is determined that the distance between the search facility and the similar facility is within a predetermined distance (step S120: Y), the control unit 21 uses the function of the destination acquisition module 110b to make the representative entrance associated with the similar facility. Is acquired as the destination DP (step S130). If a plurality of similar facilities can be searched, the representative entrance associated with the similar facility having the highest similarity in the keyword information may be acquired as the destination DP. Further, in the vehicle DB 13a, the keyword information may also be recorded for each of the internal areas A to C, and the control unit 21 may determine the optimum entrance associated with the internal areas A to C whose keyword information similarity is equal to or greater than a threshold value. May be acquired as the destination DP. Since the internal areas A to C are defined in the vehicle DB 13a, the control unit 21 determines whether or not the distance between the search facility and the internal areas A to C having similar keyword information is within a predetermined distance. Can be judged.

  When it is not determined that a similar facility whose keyword information is similar to the search facility can be searched (step S110: N), or when it is determined that the distance between the search facility and the similar facility is within a predetermined distance ( In step S120: N), the function of the destination acquisition module 110b causes the control unit 21 to determine whether or not a corresponding facility in which the coordinate SP of the search facility is within the site area R can be searched (step S140). That is, when a facility whose keyword information is similar to that of the search facility and whose position is close is not defined in the vehicle DB 13a, the control unit 21 selects a corresponding facility in which the coordinate SP of the search facility is within the site area R for the vehicle. Search from DB 13a.

  When it is determined that the corresponding facility whose coordinate SP of the search facility is within the site area R has been searched (step S140: Y), the control unit 21 determines which coordinate SP of the search facility is any by the function of the destination acquisition module 110b. It is determined whether the area is within the internal areas A to C (step S150). That is, when the coordinate SP of the search facility is in the site area R of any corresponding facility, the control unit 21 further has the coordinate SP of the search facility in any of the internal areas A to C in the site area R. It is determined whether or not.

  When it is determined that the coordinate SP of the search facility is in any one of the internal areas A to C (step S150: Y), the control unit 21 uses the function of the destination acquisition module 110b to cause the control unit 21 to store the coordinate SP of the search facility. The optimum entrance associated with the areas A to C is acquired as the destination DP (step S160). That is, the control unit 21 retrieves the internal areas A to C where the coordinates SP exist from the vehicle DB 13a, and acquires the optimum entrances G1 to G3 as the destination DP to go to the retrieved internal areas A to C. . In the example of FIG. 2A, the entrance G3 closest to the internal region C is acquired as the destination DP.

  When it is not determined that the coordinate SP of the search facility is in any of the internal areas A to C (step S150: N), the control unit 21 is associated with the corresponding facility by the function of the destination acquisition module 110b. The representative entrance is acquired as the destination DP (step S170). That is, the control unit 21 acquires the representative entrance associated with the site area R where the coordinates SP of the search facility exist as the destination DP. In the example of FIG. 2B, the entrance G2, which is the representative entrance of the site area R, is acquired as the destination DP.

  If it is not determined that the corresponding facility whose coordinate SP of the search facility is within the site area R has been searched (step S140: N), the control unit 21 uses the function of the destination acquisition module 110b to set the coordinate SP of the search facility to the highest. A point on a nearby road is acquired as the destination DP (step S180). That is, when the coordinate SP of the search facility is not within the site area R of any of the facilities, the control unit 21 sets a point on the road section closest to the coordinate SP of the search facility among the points reachable by the vehicle in the map information 13b. To obtain the destination DP as the destination DP. By executing the above destination acquisition processing, a point where the vehicle can arrive can be acquired as the destination DP, and a planned travel route to the destination DP can be searched.

(3) Other embodiments:
In the embodiment, the destination acquisition program 110 and the vehicle DB 13a are installed in the vehicle-mounted device 10, but the search facility search condition is transmitted to the search server 20, and the search facility information is acquired from the search server 20. The destination acquisition program 110 and the vehicle DB 13a may be installed in the smartphone 30. That is, search facility data may be exchanged between programs executed on the smartphone 30. Of course, a program for transmitting the search condition of the search facility to the search server 20 and acquiring the search facility information from the search server 20 may be installed in the vehicle-mounted device 110.

  Moreover, in the destination acquisition process of the said embodiment, although the similar facility was searched first, you may not necessarily search a similar facility. That is, the control unit 21 may search for a corresponding facility from the beginning without searching for a similar facility. Moreover, in the said embodiment, even if it is a facility where keyword information is not similar, it can search as a corresponding | compatible facility. In general, the search DB 23a on the Internet has a higher freshness of information than the vehicle DB 13a recorded in the vehicle-mounted device 10, and when a tenant or the like is changed, the name of the store after the change is reflected only in the search DB 23a. There is a great possibility. In such a case, there is a high possibility that similar facilities with similar keyword information cannot be searched. However, since the corresponding facility is searched based on the coordinates SP of the search facility and the site area R and the internal areas A to C, the vehicle Even if there is a difference in the freshness of information between the DB 13a for use and the search DB 23a, the possibility that the corresponding facility can be searched can be increased. For example, when the last update time of the vehicle DB 13a and the search DB 23a is equal to or greater than a threshold value, the process may be switched to execute the processes after step S140. Of course, when the corresponding facility cannot be searched by performing the processing after step S140 first, the processing of steps S110 to S130 may be executed.

  Also, the search DB 23a on the Internet reflects post information corresponding to a site area R and internal areas A to C defined in the vehicle DB 13a (such as a sales unit area within the same tenant). there is a possibility. Even when a search facility corresponding to such a fine area is searched, entrances G1 to G3 suitable for a wider site area R and internal areas A to C including the coordinates SP of the search facility are used as the destination DP. You can get it.

  Moreover, in the said embodiment, although the corresponding | compatible facility in which several internal area | region AC exists in the single site area R was illustrated, internal area AC was necessarily defined in the site area R. It does not have to be. That is, in the vehicle DB 13a, it is only necessary that the entrances G1 to G3 are associated with the site area R. When a facility in which the internal areas A to C are not defined is searched as a corresponding facility, the control unit 21 Any of the entrances G1 to G3 associated with the site area R may be acquired as the destination DP. In this case, the control unit 21 may acquire the representative entrance as the destination DP, or may acquire the entrance closest to the coordinate SP of the search facility as the destination DP.

  Furthermore, when the coordinate SP of the search facility does not exist in any of the internal areas A to C in the site area R, the control unit 21 is not necessarily the most representative of the plurality of entrances G1 to G3 existing in the site area R. It is not necessary to acquire the typical entrance G2 as the destination DP. For example, when the coordinate SP of the search facility does not exist in any of the internal areas A to C in the site area R, the control unit 21 acquires the entrance closest to the coordinate SP of the search facility as the destination DP. Also good. When the coordinate SP of the search facility exists in any of the internal areas A to C within the site area R, the optimum entrance of the internal area A to C where the coordinate SP exists is guided, or the representative entrance of the site area R is The user may be able to set whether to guide.

  The above embodiment is an example for carrying out the present invention, and various other embodiments can be adopted. The search provider manages a search server connected to the destination acquisition system via the Internet, and the search server searches for a search facility that matches a user's search condition in a search database in which a large number of facility information is accumulated. Search for. The search database is not a database in which only information on facilities that can be reached by vehicle is stored, but is a database that also stores facilities that can be reached on foot together with facilities that can be reached by vehicle. For example, in the search database, POI information uploaded by a general user using a mobile terminal with a GPS function such as a smartphone may be stored in the search database. Since POI information can also be uploaded for a facility where the user arrived on foot, the vehicle cannot necessarily arrive at the facility searched in the search database.

  The search facility is a facility searched from the search database by the search server using a predetermined search algorithm, and is a facility searched by the search algorithm adopted by the search server. The search server may present a candidate list of a plurality of search facilities that match the search condition to the user. The search facility acquisition unit may acquire the facility selected by the user from the candidate list as the search facility. Of course, the search facility acquisition unit may acquire a facility that most matches the search condition searched by the search server as a search facility. The facility coordinates are coordinates that can identify the location of the facility on the map, and any coordinate system may be used. For example, in the case of POI information uploaded by a general user, the coordinates of the search facility may be the coordinates of the mobile terminal at the time of upload. Further, the coordinates of the search facility may be coordinates designated by a general user on a map displayed on a touch panel display or the like. In such a case, the coordinates of the search facility are not necessarily the coordinates of the point where the vehicle can arrive.

  The search facility acquisition unit may be provided in a device different from the device that specifies the search condition of the search facility in the search server, or may be provided in the same device as the device that specifies the search condition. In addition, the search facility acquired by the application may be acquired by a search facility acquisition unit provided in the same computer as the computer that executes the application. That is, data indicating a search facility may be exchanged between programs executed by a single computer.

  The vehicle database may be recorded, for example, in an on-vehicle device mounted on the vehicle, or may be recorded on a recording medium such as a smartphone in which a vehicle navigation program is installed. The vehicle database is a database different from the search database, and is a database created for vehicles. That is, in the vehicle database, the facility information is created taking into account that the vehicle is used. The vehicle database includes information for specifying a region (polygon) on a map, and a site region is recorded in association with a facility. The site area is an area where facilities are present and a vehicle can enter. Further, the site area is an area managed by the owner or manager of an internal facility, and basically there is a parking lot where vehicles can be parked in the site area. However, the parking lot is not necessarily defined in the site area. An entrance is a point (entrance, gate, gate, etc.) where a vehicle can enter the internal region from the outside. In the vehicle database, an entrance through which the vehicle can enter may be recorded for each time zone (season, month, day of the week, time). In general, the road in the site area is a private road, the road outside the site area is a public road, and the entrance is a connection point between the public road and the private road.

  The destination acquisition unit searches for a corresponding facility that is a facility whose coordinates of the search facility exist within the site area. That is, it is determined whether the search facility is a facility in a site area that can be entered by a vehicle. Then, when the corresponding facility can be searched, the destination acquisition unit acquires the entrance associated with the corresponding facility as the destination. That is, the destination acquisition unit acquires, as a destination, an entrance through which a vehicle can enter a site area where a corresponding facility exists. The destination is a point to be traveled. For example, a planned travel route via the destination may be searched by a known route search method. The entrance may be a point where the vehicle arrives (arrives or passes) on the planned travel route, and may be a transit point or a final destination. For example, in the scheduled travel route, the entrance may be a transit point, and the parking lot in the site area, the coordinates of the search facility, and the like may be the final destination. However, the destination may be at least a point that is guided to the user as a point to which the vehicle should go, and the planned travel route may not necessarily be searched.

  In the vehicle database, an optimum entrance may be recorded in association with each of a plurality of internal areas in the site area, and the destination acquisition unit is associated with the internal area where the coordinates of the search facility exist. May be acquired as a destination. As a result, even when a plurality of internal areas are defined and there are a plurality of entrances to the site area, it is possible to acquire the optimum entrance for the internal area intended by the user as the destination. The internal area is an area (polygon) smaller than the site area specified in the site area. The internal area may be an area partitioned by some structure within the site area. For example, the internal region may be a region corresponding to a building, or a region partitioned by a fence, a fence, a road, a waterway, or the like. The internal area does not necessarily have to be partitioned by a structure, and may be an area that can be distinguished from other areas in the site area. For example, the internal area may be an area for each floor in a single building or for each range within the same floor. For example, one site area may be defined in the entire complex commercial facility, and the internal area may be partitioned for each tenant of the complex commercial facility.

  The entrance associated with the internal area may be an entrance suitable for going to the internal area, or an entrance through which a vehicle can enter a parking lot suitable for going to the internal area. The entrance suitable for going to the internal region may be an entrance that minimizes the distance and required time from the entrance to the internal region. Further, in the case where a dedicated passage to the internal area such as drive-through is provided, the entrance of the dedicated path may be associated with the internal area. Furthermore, in the case where a dedicated parking lot in the internal area is provided, the entrance of the dedicated parking lot may be associated with the internal area.

  Further, the destination acquisition unit acquires the most representative entrance among a plurality of entrances existing in the site area as the destination when the coordinates of the search facility do not exist in any internal area in the site area. May be. In other words, if there is a plurality of internal areas in the site area but it is not clear which internal area the user is going to go to, the most representative entrance is acquired as the destination. By setting the most representative entrance as the destination, it is possible to prevent the entrance that gives the user a sense of incongruity from becoming the destination. Here, the most representative may be the front side of a building in the site area, or the road scale (width, number of lanes, road grade, traffic outside the connected site area) Amount) may be the largest, the number of vehicles passing may be the largest, or the parking lot with the largest number of parking spaces in the site area may be entered. Good.

  Note that, as in the present invention, the method of acquiring an entrance associated with a facility as a destination can also be applied as a method or program for performing this process. In addition, the guidance information generating device, method, and program to which the method of the present invention is applied may be realized as a single device or as a plurality of devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the present invention is also realized as a recording medium for a program for controlling the guidance information generating device. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.
