  • Patent number: 7813855
    Abstract: A parking assist system for guiding a vehicle under automatic steering control from a predetermined step position via a turning-direction switching position to a parking target position. With this parking assist system, based upon an operation of a steering wheel by a driver at the predetermined stop position, a parking mode and a parking target position corresponding to that parking mode are determined. And, regardless of the amount of the operation of the steering wheel given at the time of the determination of the parking mode, the vehicle is guided with a correction such that a deflection angle of the vehicle relative to the parking target position may be a predetermined deflection angle, at a corrected switching position nearby the switching position.
