Abstract
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…
