An electropneumatic valve arrangement is configured to actuate a parking brake function of an electropneumatic brake system of a commercial vehicle, with a bistable pilot control unit having an electromagnetic solenoid valve, which modulates a pilot pressure in dependence on an electronic parking brake signal; and a main valve unit, which receives the pilot pressure and modulates a parking brake pressure at least at one spring accumulator connection in dependence on the pilot pressure. The solenoid valve has a safety control connection for receiving a safety control pressure, supplies the pilot control unit with supply pressure or connects it to an air-purging in dependence on the safety control pressure. The safety control pressure is a pressure modulated by the solenoid valve or a pressure derived from it. A method is for controlling a parking brake function of a commercial vehicle having an electropneumatic brake system.
