Abstract
In 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.
Claims11
Electropneumatic brake system for motor vehicles, having a pedal-operated braking power generator for control of a valve device which modulates pressure mediums for the brake operation further comprising:
- a) the braking power generator operating at least one electric control circuit and at least one pressure medium circuit,
- b) an electronic control unit receiving an electric signal from the braking power generator and generating electrical control signals,
- c) a pressure modulator in the pressure medium circuit with the valve device, the pressure modulator converts the electrical control signals from the electronic control unit into a proportional output pressure for controlling the valve device and, when there is no electrical control signal, provides a corresponding proportional output pressure for the control of the valve device from the braking power generator.
