Abstract
A control system is provided for controlling the driving stability of a vehicle which has a steering angle and a plurality of brakes to which respective braking pressures are applied. Each brake has valves for adjusting the brake pressure applied to the brake, individually. A sensor determines the steering angle. A yawing moment controller, receives the steering angle, and determines a yawing moment that is applied to the vehicle to prevent an undesirable yaw angle, yaw rate or yaw acceleration. Distribution logic receives the output of the yawing moment controller and determines pressure adjustments that are applied to each brake, individually, to apply the yawing moment to the vehicle. A valve switch timing facility receives the pressure adjustments determined by the distribution logic, and calculates valve switching times which are used to open and close the valves of each brake, individually, so as to perform the pressure adjustments.
