ABSTRACT:
A vehicle brake system including a brake force booster, controllable a brake pedal, for actuating a main brake cylinder in order to supply wheel brake cylinders with braking pressure for service braking operations and also includes brake pressure control valves, which direct braking pressures into individual wheel brake cylinders if there is a danger that the wheels will lock during braking. To this end, pressure is supplied to the brake pressure control valves from the brake force booster via controlled valves. In order to be able to reduce drive slip as well, the controlled valves are embodied as a switchover valve, so that pressure can be directed to the brake pressure control valves directly from a pressure supply container bypassing the brake force booster. The vehicle brake system is inexpensively further embodied for reducing drive slip by modifying the control valves.
