Abstract
An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.
