Abstract
Apparatus for controlling an automotive vehicle is provided. The vehicle has a plurality of wheels which contact a pavement surface. Each wheel has an individually operable brake. A yawing moment control mechanism determines a moment that is applied to the vehicle to prevent an undesirable yaw angle, yaw rate or yaw acceleration. A slip determining mechanism determines a longitudinal slip value of each of the wheels, individually. A distribution logic mechanism determines an individual braking pressure to be applied to each respective one of the brakes based on the moment. The distribution logic mechanism includes a facility for selectively actuating at least one of the brakes so that the longitudinal slip value of the wheel to which the one brake corresponds is greater than a longitudinal slip value at which the coefficient of friction between the wheel and the surface reaches a maximum value, without actuating all of the brakes at longitudinal slip values above the maximum friction longitudinal slip value.
