Abstract
A hydraulic brake system with anti-lock control and traction slip control having a multiple-circuit master cylinder, inlet valves and outlet valves, a pressure fluid supply reservoir, an auxiliary-pressure supply system, an electronic control unit, and pedal-travel sensors and/or switches. The outlet valves which connect the wheel brakes of the non-driven wheels with the pressure fluid supply reservoir are driven temporarily or pulsewise in the traction slip control mode in order to safeguard that even in the event of a so-called braking intervention during the traction slip control mode, the travel of the brake pedal can be recognized by the travel switches and travel sensors which permits detection of the transition from the traction slip control mode to the braking mode.
