Abstract
An electronically controllable brake actuation system for motor vehicles is proposed, with a master cylinder actuated by means of an actuating pedal, said cylinder with brake pressure transducers driven by an electronic control unit, to which wheel brakes of the motor vehicle are directly connected and which are connectable with the master cylinder by means of hydraulic linkages that can be locked by valve devices, with at least one sensor device to recognize the drivers desired deceleration and also with at least one simulator chamber cooperating with the master cylinder. In order to improve the function of a system of this kind, in particular for ASR control processes, it is proposed through this invention that the valve devices be designed as electromagnetic valves driven by the electronic control unit and that the pressure-volume characteristic of the simulator chamber is independent of that of the wheel brakes.
