ABSTRACT:
A vehicle is prevented from being moved in an unanticipated direction at a target position or a moving direction reversing position on a locus of movement based on an automatic steering operation. When a vehicle has been moved from a start position through a moving-direction reversing position to reach a target position by automatic steering control for moving the vehicle along a previously stored locus of movement, thereby finishing the automatic steering control, a driver further moves the vehicle backwards from the target position to a parking position. At this time, if the driver has his or her hands released from a steering wheel, and the course of movement of the vehicle is disturbed due to an external disturbance such as an undulation in the road surface, the steering angle of a wheel is maintained so that it is not varied from a steering angle at the target position. Further, even when the vehicle has been moved to a position past the moving direction reversing position, the steering angle of the wheel is maintained at the steering angle at the moving direction reversing position.
