In step 3, the rear part of the parking area, for example, FIG.
In the examples shown in (a) and (b), the situation in the range 61 is recognized. In step 4, it is determined whether or not a wheel chock is installed at the rear of the parking area. As shown in FIG. 5, when there is a buckle at the rear of the parking area, a buckle, which is a three-dimensional object, can be detected by, for example, a moving stereo method. As shown in FIG. 6, at the observation point A, the corner of the wheel stopper and the white line in the figure are projected at the same position on the imaging surface, but the observation point B
Then both are projected at different positions. In this way, as the vehicle moves, the corners of the three-dimensional object having a height from the road surface look different from the parking frame drawn on the road surface. Can be recognized. If there is a wheel stop, the process proceeds to step 5, where the position where the rear wheel of the vehicle contacts the wheel stop 31 is set as the target stop position as shown in FIG. 7, and the braking / driving force is controlled so that the vehicle stops at that position. I do. At this time, the brake actuator 4 is drive-controlled to generate a braking force according to the distance to the target stop position.

On the other hand, if there is no wheel stop at the rear of the parking area, the routine proceeds to step 6, where it is determined whether or not a frame indicating the parking position is drawn at the rear of the parking area. The parking frame as shown in FIG. 8 can be detected by, for example, the edge detection method. Generally, a parking frame is drawn with a white line or a yellow line having a high contrast with respect to a road surface in order to enhance visibility. Therefore, when an edge enhancement process such as a sobel filter is performed on the captured image, an image in which the boundary between the road surface and the parking frame is enhanced as shown in FIG. 9 is obtained. If a straight line detection process is performed on this processed image, a parking frame can be detected. If the parking frame is drawn, the process proceeds to step 7, and as shown in FIG. 10, a position where a half of the space for a person to stand between the rear end of the vehicle and the parking frame is secured as a target stop position. The braking / driving force is controlled so that the vehicle stops at the position. At this time, the brake actuator 4 is drive-controlled to generate a braking force according to the distance to the target stop position.

If there is no wheel chock at the rear of the parking area and no parking frame is drawn, the process proceeds to step 8, and it is determined whether or not there is a wall at the rear of the parking area at the rear end of the parking position. As shown in FIG. 11, the rear wall surface of the parking area can be detected by, for example, the moving stereo method or the edge detection method described above. In the case of detection by the moving stereo method, FIG. 1 is used based on the principle described with reference to FIG.
The change in the appearance of the road surface portion 131 and the wall surface portion 132 shown in FIG. 1 is detected, and the existence of the wall surface portion 132 is recognized. If there is a wall surface, the process proceeds to step 9, where a position where a space for a person to stand between the rear end of the vehicle and the wall surface is secured as shown in FIG. 12 is set as a target stop position, and braking / driving is performed to stop the vehicle at that position. Control the power. At this time, the brake actuator 4 is drive-controlled to generate a braking force according to the distance to the target stop position.

In step 11, a change in the gradient of the road surface in the parking area is detected. The gradient of the road surface in the parking area is detected from a change in the appearance of the road surface by, for example, the moving stereo method, and a portion that is continuously flat from the entrance of the parking area is recognized. In step 12, it is determined whether the flat portion is long enough to park the vehicle. If there is a sufficient parking space where the length of the flat portion is longer than the length of the vehicle, the process proceeds to step 13, where the position where the front end of the vehicle comes to the entrance of the parking area is set as the target stop position as shown in FIG. Controls the braking / driving force so that the vehicle stops. At this time, the brake actuator 4 is drive-controlled to generate a braking force according to the distance to the target stop position.

On the other hand, if the length of the flat portion of the parking area is shorter than the length of the vehicle and there is not enough parking space, the process proceeds to step 14, and as shown in FIG. A position where a space for a person to stand between the continuous flat portion and the rear end is secured is set as a target stop position, and the braking / driving force is controlled so that the vehicle stops at that position. At this time, the brake actuator 4 is drive-controlled to generate a braking force according to the distance to the target stop position. With the above processing, the target stop position of the vehicle can be determined, and the vehicle can be automatically moved to the parking position and parked.
