Abstract: The present invention discloses a method of operating an anti-lock automotive vehicle brake system for driving stability control and/or traction slip control (DSC/TCS) including a brake power booster operable irrespective of the driver's wish. According to this method, the brake power booster is actuated irrespective of the driver's wish for prefilling the vehicle wheel brakes, and further pressure increase in the vehicle wheel brakes upon completion of the prefilling action is carried out by the ABS return pump.

Abstract: Apparatus for improving the driving behavior of a vehicle is provided. The vehicle has front and rear axles, each having a plurality of wheels. Each wheel-has a brake. Sensor are provided for measuring the rotational speed of each wheel, the vehicle yaw rate and the vehicle lateral acceleration. An anti-lock braking system provides first preset pressure values for controlling each brake, to prevent the wheels from locking during braking. A traction slip control system provides second preset pressure values for controlling each brake, to prevent the wheels from slipping during acceleration. A brake effort proportioning system provides third preset pressure values for distributing braking pressure between the wheels of the front axle and the wheels of the rear axle. A yawing moment controller provides fourth preset pressure values used to control each brake during cornering, to avoid application to the vehicle of an unbalanced moment which would cause the vehicle to understeer or oversteer.

Abstract: Apparatus for controlling an automotive vehicle is provided. The vehicle has a plurality of wheels, each wheel having an individually operable brake. The apparatus comprises a mechanism for determining the steering angle of the vehicle. A yawing moment controller receives the steering angle and determines a 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. The distribution logic determines a respectively different weighted coefficient for each individual brake, and an individual braking pressure to be applied to each respective one of the brakes based on the moment and the respective weighted coefficient of the one brake.
