Abstract

An electropneumatic pressure regulating module, formed as a structural unit, is described for an electropneumatic brake system of a vehicle, including: at least two separately regulable pressure regulating channels, wherein a regulated working pressure, acting at at least one working pressure port, for at least one brake application device of the brake system is generated for each pressure regulating channel on the basis of working air originating from at least one compressed air store and as a function of braking demand signals of a brake transducer, in which to form pressure regulating channels having separate pneumatic circuits, each pressure regulating channel is assigned at least one dedicated storage pressure port which can be connected to a dedicated compressed air store, and in which the pneumatic flow paths of each pressure regulating channel are formed so as to be pneumatically separate, at least proceeding from the respective storage pressure port as far as the respective working pressure port, from the pneumatic flow paths of a respective other pressure regulating channel.
