In semi-automatic parking and fully automatic parking, the parking support system performs all or part of judgment and driving operation on behalf of the driver. As a result, the driver does not always have to be aware of road conditions and driving routes, and as a result, the driving load on the driver is greatly reduced. On the other hand, depending on the degree of automation of automatic parking, there are scenes where the driver needs to operate and determine to assist automatic parking, such as some driving operations, parking continuation determination, and emergency stop determination. In such a scene, the driver needs to immediately grasp the route information such as the road conditions around the vehicle, the parking route, and the parking progress. In particular, not only the current operations and information that the driver should know, but also that the driver can always grasp the timing that requires judgment and operation in the overall parking support from the start of parking to the end of parking, It is important to realize instantaneous judgment. For this reason, it is desired for a vehicle capable of automatic parking so that the passenger can inform the route information and the progress of parking in an intuitive manner and thus immediately.

Here, in the technique of Patent Document 1, the passenger can intuitively grasp the progress of parking support by changing the notification sound. However, there is a problem that the driver cannot grasp the progress of a plurality of types of operations in parking, such as a plurality of turn-back operations. Further, in the technique of Patent Document 2, the time required until the end of parking assistance is reported, but the location (route information) and the time point (progress status) are intuitively grasped about the position that requires operation or judgment. It is difficult to do.

Therefore, the present invention has been made in view of the above-described problems, and an object thereof is to provide a technique capable of grasping the current point and the specific position in the required parking time.

An output control device according to the present invention is an output control device that controls display of a display device mounted on a vehicle capable of automatic parking, and includes a route information acquisition unit that acquires route information including a target route of automatic parking; The progress information acquisition unit for acquiring the progress of automatic parking, the target route included in the route information acquired by the route information acquisition unit, and the graph indicating the progress acquired by the progress information acquisition unit are displayed on the display device. An output control unit. The output control unit displays the current position of the vehicle in the target route to be displayed and the specific position in the target route to be displayed on the display device so that the current position can be identified. And the specific position are displayed on the display device in an identifiable manner corresponding to the required parking time.

According to the present invention, the current point of the vehicle in the target route to be displayed and the specific position in the target route to be displayed are identifiable, and the current point of the vehicle is displayed in the progress graph to be displayed. And the specific position are displayed so as to be identifiable in correspondence with the required parking time.
