Abstract
A control system for steering front wheels or rear wheels of a controlled vehicle has a processing unit such as a microcomputer which determines a desired value of a dynamical variable such as yaw acceleration corresponding to sensed steering wheel angle and sensed vehicle speed by solving equations of motion of a vehicle in which parameters are set equal to desired values determined by a desired vehicle. From the desired value of the dynamical variable, the processing unit determines a desired value of a steering angle of the front or rear wheels, and commands a hydraulic actuator to steer the front or rear wheels so that the controlled vehicle behaves as if it were the desired vehicle. The controlled vehicle may have a mechanical steering linkage for steering the front wheels in a conventional manner, and the control system may be arranged to control the steering angle of the rear wheels.
