  • Method for the control of a slip-controlled brake system and device for implementing the method
    Patent number: 4702531
    Abstract: For the control of a brake-slip controlled brake system the brake pedal force assisted by auxiliary force is transmitted onto a master cylinder (10, 10', 33) and from said onto the wheel brake cylinders via several pressure fluid paths that are adapted to be closed independently of one another. The wheel rotational behavior and the vehicle velocity will be measured with sensors (S1 through S4), the signals will be logically combined, and therefrom control signals will be generated for electromagnetically actuatable directional control valves (15, 16, 17, 19, 35, 36, 37, 42, 43, 52). During control action, the pedal force (F) that is directed to the master cylinder and assisted by auxiliary force will be compensated temporarily by an opposed force, as a result whereof the pressure rise in the master cylinder will be retarded or pressure will even be decreased.
