Patent ID: 8226175

Claim:
A brake system of the brake-by-wire type for a motor vehicle comprising: a) a brake activation unit which can be activated by a brake pedal and can be connected to wheel brakes of the vehicle outside a brake-by-wire operating mode, b) a pressure source which can be actuated by an electronic control unit and can be connected to the wheel brakes of the vehicle in the brake-by-wire operating mode, c) means for sensing a driver's deceleration request, d) a pedal travel simulator which interacts with the brake pedal that is formed by at least one spring element and a damping element, and, by means of which, a restoring force acting on the brake pedal can be simulated in the brake-by-wire operating mode independently of actuation of the pressure source, and e) an electrohydraulic device which can be actuated by the electronic control unit, the electrohydraulic device comprising a check valve, the electrohydraulic device operable to activate the pedal travel simulator in the brake-by-wire operating mode and to at least partially deactivate the pedal travel simulator outside the brake-by-wire operating mode using the check valve, wherein the damping element is fixedly mounted to the pedal block and interacts with the electrohydraulic device which is fixedly mounted to and capable of pivoting together with the brake pedal.
