ABSTRACT:
During ASR control of spinning drive wheels, the pressure level in the wheel brake with the highest pressure level is modulated by driving a switching valve USV which affects the pressure in all the wheel brakes of the brake circuit, whereas the pressure level in the other wheel brake or brakes is controlled by way of wheel-specific inlet and outlet valves. The intake control valve ASV is kept open through the entire ASR control period. As a result, the electrically actuated ASV can be replaced by a hydraulically actuated ASV.
