Date Jun. 22, 1995In the case of an electropneumatic brake system for motor vehicles, a pedal-operated braking power generator is provided which acts electrically upon an electronic control unit and feeds pneumatically into a pressure modulator which includes a proportional valve device and a reversing valve device. The pressure modulator is also controlled by desired electric value signals of the electronic control unit and is used for activating a valve device which modulates pressure mediums for the brake operation of the brake system. When the electric control fails, the pressure modulator operates redundantly.
