ABSTRACT:
In a four-wheel steering system for an automotive vehicle, a travel speed of the vehicle is detected to determine parameter related to the detected vehicle speed, and lateral deviation of the vehicle is further detected to determine a steering angle of rear road wheels on a basis of the detected lateral deviation of the vehicle and the determined parameter. When the detected vehicle speed becomes unreliable due to skid condition of either one of the road wheels, the steering angle of the rear road wheels is determined on a basis of the detected lateral deviation and the fixed parameter.
