ABSTRACT:
An anti-lock-controlled brake system with a auxiliary-force-assisted braking pressure generator accommodates a master cylinder in which at least one wheel brake is connected to a main pressure line, with an auxiliary hydraulic pressure pump connected to an auxiliary pressure line the system further includes wheel sensors and electronic circuits for detecting the rotational behavior of the wheels and for generating electric braking pressure control signals which, for the purpose of slip control, control the electromagnetically operable inlet valves and outlet valves inserted into the pressure medium lines. A pressure limiting valve is responsive to the pressure of the auxiliary pressure pump and to a pressure acting on the wheel brake to control the outlet pressure of the pump.
