ABSTRACT:
A steering control system for controlling either or both of the front and rear wheel steer angles of a vehicle includes a steering input sensor for sensing a steering input such as a steering wheel angle and an electronic control unit which includes a basic control section for calculating a desired steer angle in accordance with the sensed steering input and a time derivative of the steering input. In order to improve the vehicle stability by eliminating unstable vehicle response to driver's unconscious fluctuating steering operation, the control unit further includes a gain adjusting section for discriminating unconscious operation from intentional steering operation by comparing the time rate of change of the steering input with a predetermined reference level, and for decreasing the gain by which the derivative of the steering input is multiplied in determining the desired steer angle when the time rate of change of the steering input is smaller than the reference level.
