A steering control system for a wheeled vehicle, comprises a steering actuator for steering the vehicle by varying one of front and rear wheel steer angles in response to a control signal representing a control steering input, a sensor for sensing a vehicle motion such as a yaw rate, and a controller for controlling the vehicle motion by producing the control signal. The controller determines an estimated vehicle motion variable from a driver's steering command and the control steering input by using one or more predetermined estimator transfer characteristics, compares the sensed and estimated vehicle motion variables to determine a deviation therebetween, and determines the control steering input so as to reduce the deviation by using a predetermined compensator transfer characteristic and a predetermined filter transfer characteristic for filtering the deviation.
