ABSTRACT:
A four-wheel steering apparatus operates such that only when the vehicle velocity is lower than a predetermined value, is the provision of the steering angle to the rear wheels electrically controlled by the steering angle sensor for the front wheels and vehicle velocity sensor while at a high-speed traveling, the provision of the steering angle to the rear wheels is performed by the compliance steering mechanism. Hence the control and stability are improved as compared with the case where the steering angle is given to the rear wheels electrically even at a high-speed traveling.
