  Hereinafter, the automatic parking process of the automatic parking control apparatus 101 will be described along the flowchart of FIG. First, the parking availability determination unit 13 determines whether or not automatic parking of the host vehicle is possible (step S11).

  Specifically, the parking availability determination unit 13 determines that automatic parking is possible if there is a parking area of the host vehicle, and that automatic parking is not possible if there is no parking area. For example, when parking the own vehicle in a fixed parking area such as a parking lot at a home site or a parking lot with a monthly contract, the user can designate the parking area as a parking area of the own vehicle. Then, the parking availability determination unit 13 determines whether an obstacle or a person such as another vehicle exists in the parking area based on the peripheral information, and determines that the parking area is a parking available area if it does not exist.

  In addition, when a parking area is not specified, such as when parking in an empty parking area having a plurality of parking areas, the parking availability determination unit 13 searches for a parking area based on the surrounding information. Specifically, the parking availability determination unit 13 detects a parking area based on, for example, white line detection information, and can park the parking area when there are no other vehicles, obstacles, people, or the like in the parking area. Judge as an area.

  Depending on the position of the host vehicle, the surrounding information detection device 22 may not be able to detect the surrounding information for all parking sections in the parking lot. In such a case, the vehicle control unit 14 controls the vehicle control device 23 based on the position information of the host vehicle and the surrounding information, causes the host vehicle to travel in the parking lot, and moves the position of the host vehicle as appropriate. The determination unit 13 may be configured to search for a parking area from the entire parking lot.

  When there is a parking area, the parking availability determination unit 13 determines that the vehicle can be parked automatically (Yes in step S11). And the vehicle control part 14 controls the vehicle control apparatus 23, and makes the own vehicle park automatically in the parking possible area searched at step S11 (step S12). In addition, when the parking possibility determination part 13 searches a parking possible area | region by step S11, you may use the parking possible area | region discovered first in step S12, or after searching the whole search area, such as a parking lot, parking permission / non-permission One parking area selected by the determination unit 13 may be used in step S12.

  Next, the vehicle control unit 14 determines whether or not automatic parking is completed (step S13), and if automatic parking is not completed, the process returns to step S12 and continues automatic parking control. On the other hand, if the automatic parking is completed, the wireless communication unit 11 transmits an automatic parking completion notification to the smartphone 2 (step S14). Here, the wireless communication unit 11 refers to the information storage unit 15 and transmits an automatic parking completion notification to the smartphone 2 which is a portable device registered as a transmission destination of the automatic parking status.
