    • 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.
    • 自动转向控制执行自动停车控制,其自动地引导车辆的可转向车轮,而不需要驾驶员执行方向盘操作,使得可转向车轮的实际转向角跟随变化的目标转向角,由此车辆移动 到目标停车状态。 由于转向驱动力的转向驱动力不足而导致实际的转向角不能跟随目标转向角,所以进行制动力差赋予控制,以对预定的制动力施加在位于目标车辆内的可转向轮上 轨迹。 结果,在可转向轮中产生转向力矩。 该转向力矩用作用于补偿转向致动器的转向驱动力不足的力。 结果,实际的转向角精确地跟随目标转向角。
