The invention relates to an electric parking brake, in particular for a utility vehicle, comprising at least two compressed-air outputs (72, 73), an electrically controllable valve arrangement (20) for controlling a distribution of compressed air to the compressed-air outputs (72, 73), comprising a bistable valve (24), a compressed-air input which can be connected to a compressed-air supply (50) for supplying compressed air from a compressor (51) and/or from a compressed-air reservoir to the valve arrangement (20) and to the compressed-air outputs (72, 73). The object of the invention is to specify an electronic parking brake which has as low a number of switchable valves as possible and which reliably supplies compressed air to the compressed-air outputs. The object is achieved in that the bistable valve (24) is supplied with compressed air at the input end by the compressed-air supply (50) at least during a de-energized state of the valve arrangement, said compressed air being at a pressure which is made available by the compressor (51) and/or the compressed-air reservoir. |
