ABSTRACT:
A four-wheel steering system for a motor vehicle steers motor vehicle rear wheels based on a steering angle ratio between front and rear wheels based on a vehicle speed, and a front wheel steering angle. The steering angle ratio is of a negative value or a relatively small positive value when the vehicle speed is in a medium speed range or a high speed range and the front wheel steering angle is in a relatively small range. The motor vehicle is controlled to turn well when the front wheel steering angle is in the relative small range while the motor vehicle is running in the medium and high speed ranges.
