Abstract
A control system for a wheeled vehicle, comprises a brake actuator for controlling a behavior of the vehicle during braking by producing a braking force difference between a left wheel braking force and a right wheel braking force in response to a control signal, a sensor for sensing an actual vehicle motion variable 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 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 magnitude of the control signal so as to reduce the deviation by using a predetermined compensator transfer characteristic and a predetermined filter transfer characteristic for filtering the deviation.
