Can do. As a result, the present invention does not complicate the work process when creating and adding data on facilities and parking lots, can appropriately guide parking lots that can be reached from the facilities by walking route, and can reduce the processing load during search. In addition, there is an effect that it can be performed in a short time.

  Specifically, in the prior art (Patent Document 1 and the like), since the peripheral parking lot information is given for each POI, the positional relationship between the POI and the parking lot must be investigated and linked. Data creation becomes complicated, for example, when a new POI or a parking lot is added to the data, the problem arises that the positional relationship between the POI and the parking lot must be investigated and linked data must be created. However, in the present invention, it is possible to provide a parking lot that can be used using the service area data associated with the facility data without linking and storing the facility data and the parking lot data. As a result, there is an effect that the work process at the time of data creation / addition of facilities and parking lots is not complicated.

  In the prior art (Patent Document 1, etc.), since priority is determined based on the linear distance between the POI and the parking lot, a parking lot that cannot actually be reached by walking route is guided to the user as a recommended parking lot. However, in the present invention, a route search is made in advance from the facility within a predetermined time without measuring the distance between the facility and the parking lot by a straight line distance. Since the service area data for identifying the service area on the map data that the user can reach on foot is stored in association with each facility, it is possible to appropriately guide the parking lot that can be reached on foot from the facility. There is an effect.

  Further, in the prior art (Patent Document 1, etc.), in order to avoid a situation where a parking lot that cannot actually be reached by walking route is guided to the user as a recommended parking lot, a walking route is searched each time instead of a straight distance. However, even if the priority is determined based on the distance of the route, there is a problem that the walking route search processing is required by “the number of POIs × the number of parking lots”, the processing load during the search is heavy, and time is required. However, in the present invention, a service area that specifies a service area on map data that can be reached on foot from the facility within a predetermined time by performing a route search in advance from the facility. Since data can be stored in association with each facility, and a parking area that can be used can be provided using the service area data associated with the facility data, the processing load during the search can be reduced, and An effect that can be performed in time.

  Further, according to the present invention, when transmitting the recommended parking list, the recommended parking list further including the generated determination image is transmitted to the navigation device and received when the recommended parking list is displayed. The determination image included in the recommended parking lot list can be displayed via the display unit. Thereby, this invention has an effect that it can notify a user intuitively the position of the recommended parking lot contained in the determination image which shows a service area.

  According to the present invention, the determination image can be an image in which the service area is superimposed and displayed on the corresponding map data stored in the storage unit. Thereby, this invention produces the effect that the position on the map of the parking lot which exists in the service area which can be reached | attained with a walk route from a facility can be specified concretely. For example, since a parking lot that can be used on a walking route from a desired facility can be specifically identified on a map, a facility that may exist on the walking route from the facility to the parking lot that the user may desire Etc., such as being able to notify the user in advance.

  Further, according to the present invention, the service area data can be data for displaying the service area in a polygon on the map data. As a result, the present invention has an effect that the range on the map corresponding to the reachable area that can be reached by walking route from the facility can be clearly displayed by polygon display. For example, when displaying a list of recommended parking lots to the user, it is possible to clearly tell where the parking lot is located in the service area, so it is located at the end of the service area There is an effect that it is possible to inform the user more intuitively whether it is a parking lot or the like.

  Further, according to the present invention, when a plurality of facilities are extracted in the generation of the determination image, one determination in which the service area areas of a plurality of service area data corresponding to the plurality of facilities are superimposed and drawn. An image can be generated. Thereby, even if the user selects a plurality of facilities, the present invention superimposes the service area with a plurality of parking lots existing in the service area that can be reached from the facilities by a walking route. Thus, there is an effect that the image can be extracted using one determination image drawn.

  Further, according to the present invention, in the generation of the determination image, a determination image is generated by adding pixel values corresponding to the number of overlaps for the overlapping area of the service area, and in the extraction of the parking lot, the parking lot of the storage unit Based on the position information, it is possible to preferentially extract a parking lot that exists within a high pixel value range in the generated determination image. As a result, the present invention provides an optimal position for a user (for example, when two facilities are selected, among a plurality of parking lots within a service area that can be reached by walking route from a plurality of facilities. There is an effect that it is possible to extract a parking lot existing at an intermediate position between the two facilities.

  Further, according to the present invention, the parking lot data further includes usage condition data that defines the usage conditions of the parking lot, and the facility search conditions further include the usage conditions of the user's desired parking lot. In this extraction, it is possible to preferentially extract a parking lot that satisfies the usage conditions of the user's parking lot specified in the facility search condition based on the usage condition data of the parking lot data. As a result, the present invention is not only in an optimal position for the user, but is also optimal in consideration of the use conditions of the parking lot desired by the user (for example, use time zone, use area, vehicle type restriction, etc.). There is an effect that a parking lot can be extracted.

[Processing of navigation server 200 (server-driven type)]
Next, an example of processing of the navigation server 200 according to the second embodiment configured as described above will be described in detail with reference to FIG.

  As shown in FIG. 9, when a facility search condition is transmitted from the navigation device 100 through the input unit 116 of the navigation device 100 and a facility search condition is transmitted (step SB-1), the facility extraction of the navigation server 200 is performed. The unit 202a extracts a facility that satisfies the facility search condition from the attribute information of the facility database 206b based on the facility search condition (step SB-2). Here, the facility search condition may further include a use condition of the parking lot desired by the user.

  Then, as shown in FIG. 3A described above, the determination image generation unit 202b of the navigation server 200 converts the service area data corresponding to the facility extracted by the facility extraction unit 202a in step SB-2 into the facility database 206b. As shown in FIG. 3B described above, a determination image in which the service area specified by the service area data is drawn is generated (step SB-3). Here, the determination image means an image showing a service area corresponding to the white area portion of FIG. Further, as shown in FIG. 3C described above, the determination image may be an image in which the service area is superimposed and displayed on the corresponding map data stored in the map database 206a. The service area data may be data for displaying the service area in a polygon on the map data as shown in FIG. Further, as shown in FIG. 4A described above, the determination image generation unit 202b of the navigation server 200 performs a plurality of facilities (for example, facilities 1 to 3 in FIG. 4) by the facility extraction unit 202a in step SB-2. ) Is extracted, one determination image is drawn by superimposing service area areas (for example, service area areas 1 to 3 in FIG. 4) of a plurality of service area data corresponding to the plurality of facilities.

A determination image may be generated by adding pixel values (for example, pixel values 1 to 3 and the like) corresponding to three images.

  And the parking lot extraction part 202c of the navigation server 200 is based on the location information of the parking lots (for example, the parking lots 1-4 in FIG. 5A) stored in the parking lot database 206c. As shown in (b), by positioning the position of the parking lot on the determination image generated by the determination image generation unit 202b, it is within the range of the determination image generated by the determination image generation unit 202b in step SB-3. An existing parking lot (for example, parking lot 2 and parking lot 4 in FIG. 5C) is extracted (step SB-4). Here, the parking lot extraction unit 202c of the navigation server 200, as shown in FIG. 4B, described above, the parking lot of the parking lot database 206c (for example, the parking lots 1 to 6 in FIG. 4B). Based on the positional information, the pixel value of the determination image generated by the determination image generation unit 202b in Step SB-3 is within a high range (for example, in the overlapping region 3 having the pixel value 3 in FIG. 4B). (For example, the parking lot 4 in FIG. 4B) may be preferentially extracted. Further, the parking lot data may further include usage condition data that defines the usage conditions (for example, usage hours, usage areas, vehicle type restrictions, etc.) of the parking lot, and the parking lot extraction unit 202c includes the parking lot data. Based on the usage condition data, a parking lot that satisfies the usage conditions for the user's parking lot specified in the facility search condition may be extracted with priority.

  Then, the recommended parking lot list generation unit 202e reads the facility data of the facility extracted by the facility extraction unit 202a in Step SB-2 and the parking lot of the parking lot extracted by the parking lot extraction unit 202c in Step SB-4. Display screen data displaying a recommended parking lot list including at least data is generated (step SB-5). Here, the recommended parking lot list generation unit 202e may generate display screen data that displays the recommended parking lot list further including the determination image generated by the determination image generation unit 202b in step SB-3. As an example, as shown in FIG. 5D, the recommended parking lot list generation unit 202e displays recommended parking lots 1 and 2 corresponding to parking lots (for example, parking lots 2 and 4 etc.) present in the determination image. Display screen data of an image including the image may be generated.

  Then, as shown in FIG. 6, the recommended parking lot list display control unit 202 f transmits the display screen data of the recommended parking lot list generated by the recommended parking lot list generation unit 202 e to the navigation device 100 in step SB-5. Thus (step SB-6), control is performed to display at least part of the facility data and the parking lot data included in the recommended parking lot list via the display unit 114 (step SB-7). Here, the recommended parking lot list display control unit 202f may perform control to display the determination image included in the recommended parking lot list via the display unit 114 as illustrated in FIG.

  Above, description of an example of the process of the navigation server 200 in 2nd Embodiment is finished.
