  • Publication number: 20240425022
    Abstract: Electric equipment for a vehicle with an electropneumatic service brake device, in which at least one pneumatic brake control pressure is immediately and directly controlled to the electromagnetic backup valve, which is still being closed by a current, of at least one pressure regulating module in response to an assistance brake request signal regardless of a defect of an electric service brake circuit. For a failure of the electric service brake circuit, the electromagnetic backup valve, which is then in the currentless state, of the at least one pressure regulating module is automatically opened, and the brake pressure is immediately formed in the pressure regulating module based on the at least one pneumatic brake control pressure already present in the pressure regulating module. Thus, the reaction time of a pneumatic redundancy of the electropneumatic service brake device in response to electric defects is reduced.
