Description

The present invention relates to a vehicle approach control device, a vehicle approach control system, a vehicle approach control method, and a vehicle approach control program.

For a vehicle that uses a parking lot, there is a technique for adjusting the area in which the vehicle is parked according to the width, depth, and height of the vehicle.

For example, in the method described in Patent Document 1, the control server determines a parking area in which the vehicle can be parked based on the measured values of the width, depth, and height of the vehicle that has entered the parking lot. Further, the display device uses a floodlight to project light onto the road surface so that the parking frame indicating the parking area is displayed on the road surface.

As described above, in the method described in Patent Document 1, the control server determines the parking area based on the size of the vehicle. Further, the display device uses a floodlight to project light onto the road surface so that the parking frame is displayed on the road surface. As described above, in the method described in Patent Document 1, the parking area is determined based on the size of the vehicle. Therefore, the control server can park more vehicles in the parking lot than when the parking frame is fixed, such as when the parking frame indicating the parking area is displayed with a white line.

Further, the determination unit 52 determines an area (a parking area having a parking range of 3.2-8.0) to which PA1 is associated as parking range identification information and is not designated as a parking range for parking the first vehicle. On the other hand, PA2 is set as the parking range identification information. Further, the determination unit 52 stores the parking range (3.2-8.0) and the designated information (vacant) of the parking range identification information of PA2 in the parking range management table. In the example of the parking range management table of FIG. 9, the record of the second row is stored.

When the size of the parking area where the designated information is empty corresponds to the size of the parking area determined by the determination unit 52 with respect to the first vehicle, the determination unit 52 determines the parking area by the first vehicle. It may be determined as a parking area to be parked. When the determination unit 52 determines the parking area with empty designated information as the parking area of the first vehicle, the determination unit 52 updates the designated information in the parking range management table from empty to designated, and further, the characteristics of the first vehicle. Information identification information is stored.

Further, the determination unit 52 may specify a position where the parking frame display device 7 included in the vehicle approach control system can display the parking frame based on the parking frame display device management table.

The range may be determined. Further, the determination unit 52 may determine the parking range for designating the parking area in the direction of the height of the vehicle and the depth of the vehicle in the same manner as in the case of designating the parking range in the direction of the width of the vehicle. Further, when there is a parking area where a large vehicle cannot be parked, the determination unit 52 may preferentially park a small vehicle that can be parked in the parking area in a parking area where the large vehicle cannot be parked. .. As described above, when there is a parking area in which a vehicle satisfying a predetermined condition can be parked, the determination unit 52 may preferentially park the vehicle satisfying the predetermined condition in the parking area.

Further, the determination unit 52 may receive information indicating the sign from the specific unit 51. Further, when the information indicating the sign is received, the determination unit 52 sets the width of the vehicle and the space for opening and closing the left and right doors with respect to the first vehicle in which the information indicating the sign is specified by the specific unit 51. In addition, a parking range may be determined that specifies a parking area that includes a space according to the information indicating the sign. For example, when the information indicating the sign includes a handicapped person sign, the determination unit 52 gives the first vehicle a space for getting on and off the wheelchair in addition to the width of the vehicle and the space for opening and closing the left and right doors. A parking range may be determined to specify the parking area to be included.

The display control unit 55 receives the characteristic information identification information from the determination unit 52.

When the vehicle information display device management table shown in FIG. 12 is stored, the vehicle information display device 8 whose vehicle information display device identification information is CI1 (vehicle information display position information is 2.0) has a parking range of 0.2. The first vehicle feature information can be displayed in the parking area indicated by -3.2 (Fig. 12, line 1). Therefore, the display control unit 55 identifies the vehicle information display device 8 whose vehicle information display device identification information is CI1. Further, the control unit 53 outputs control information for displaying the first vehicle feature information on the specified vehicle information display device 8.

Further, when the control information for displaying the first vehicle feature information is output to the vehicle information display device 8, the display control unit 55 corresponds to the first vehicle feature information displayed on the vehicle information display device 8. The characteristic information identification information is stored in the vehicle information display device management table.

Further, when the vehicle is photographed in the second image in which the second point is photographed, the vehicle approach control device 5 identifies the second vehicle feature information based on the second image. Further, the vehicle approach control device 5 is an approach blocking device 10 based on the degree of similarity between the first vehicle feature information associated with the parking range corresponding to the second point and the second vehicle feature information. To control. As a result, when the similarity between the first vehicle feature information and the second vehicle feature information is low, the driver cannot park the second vehicle in the parking range corresponding to the second point. In addition, the vehicle approach control device 5 can control the approach prevention device 10. Therefore, the vehicle approach control device 5 can reduce the possibility that the driver cannot park the vehicle in the parking area where the vehicle should be parked.

Further, as described above, the vehicle approach control device 5 of the present embodiment determines the parking range for designating the parking area based on the characteristic information generated by the measurement unit of the vehicle information acquisition device 6. As a result, the vehicle approach control device 5 can specify a parking area having a different size for each first vehicle based on the size of the first vehicle. Therefore, the vehicle approach control device 5 can provide a parking area having a size suitable for each vehicle.

Further, the vehicle approach control device 5 determines the parking range based on the sign displayed on the vehicle. This makes it possible for the vehicle approach control device 5 to provide a parking area that matches the characteristics of the driver.

Further, when the degree of similarity between the second vehicle feature information and all the first vehicle feature information stored in the vehicle feature information management table is low, the vehicle approach control device 5 of the second vehicle Determine the parking range that specifies the parking area. This makes it possible to reduce the possibility that the vehicle cannot be parked when the vehicle approach control device 5 cannot correctly identify the first vehicle feature information based on the first image.

Further, the vehicle approach control device 5 outputs the image data of the second image obtained by photographing the second point to the monitoring device having a function of monitoring the parking lot based on the image data output from the predetermined photographing device. You may. As a result, the photographing device 4 can make up for the blind spot of the surveillance camera installed in the parking lot.
