ABSTRACT:
A control system for steering a controlled vehicle has a steering wheel angle sensor, a vehicle speed sensor, an actuator for altering a rear wheel steer angle, and a processor such as a microcomputer. The processor has a reference supplying section for determining a desired value of a vehicle motion variable such as a yaw rate by solving a desired mathematical vehicle model representing a postulated vehicle, and an actual motion estimating section for determining an estimated value of the vehicle motion variable by solving an actual vehicle model representing the controlled vehicle. The control system alters the rear wheel steer angle so as to reduce the difference between the desired and estimated values of the motion variable.
