An electropneumatic valve assembly for actuating a parking brake function of an electropneumatic brake system of a commercial vehicle has a parking brake valve unit which receives supply pressure from a supply pressure path and outputs a parking brake pressure at least at one spring brake port in dependence on an electronic parking brake signal. A pneumatically switchable safety valve connects the supply pressure path to at least a first compressed air supply and in a supply position connects the compressed air supply to the supply pressure path and in an air release position releases air from the supply pressure path. A pneumatic safety valve control port of the safety valve is connected to the at least one compressed air supply. The safety valve switches into the supply position if the supply pressure provided by the at least a first compressed air supply exceeds a threshold value.
