A control process for the driving stability control of a motor vehicle is provided. The signal sent out by a control law unit to generate the necessary additional torque is sent to a distribution logic unit, which subsequently sends the pressure signals used to actuate the individual wheel brakes. The superimposition of these pressure signals and the pressure signal characterizing the driver's desire to brake (as well as the subsequent superimposition of these adjusting signals to adjusting signals arriving from other brake pressure controllers, such as ABS, TSC, EBV) leads to interfaces in which differing physical variables must be compared or superimposed. The necessary conversion of these variables is expensive and increases the inaccuracy of the control system. Simplified interfaces are provided, to achieve improved processing of the brake pressure desired by the driver, and possibly to avoid the conversion of the individual signal variables. Pressure gradient signals are sent, to the output of the distribution logic unit, and are superimposed with corresponding gradient signals from other brake pressure control circuits. A priority circuit processes the pressure signals of the individual wheels such that commands to reduce the pressure are processed first, after which the commands to hold pressure, and finally the commands to build up pressure are processed.

[ What is claimed:] [1.] In a yaw control system of a vehicle having a plurality of wheel brakes, a method for determining pressure adjustments for the brakes, individually, and applying the pressure adjustments to adjust a yawing moment that is applied to the vehicle by the brakes, comprising the steps of:(1) detecting a condition in which an increase in the brake pressure applied to a first one of the brakes is required to apply the yawing moment to the vehicle while a driver of the vehicle is actuating the brakes to apply a first braking force to the vehicle;(2) determining a reduction in pressure that is applied to a second one of the brakes, such that a total braking force applied to the vehicle does not exceed the first braking force when the pressure applied to the first brake is increased; and(3) reducing pressure in the second brake before initiating the increase in the pressure applied to the first brake.
