Electric parking brake

An electric parking brake, comprising:

• at least two compressed-air outlets;
• an electrically controllable valve arrangement for controlling a distribution of compressed air to the compressed-air outlets, the valve arrangement including a bistable valve, a first solenoid valve, a second solenoid valve, a third valve, and a first select high valve;
• a compressed-air inlet which is connectable to a compressed-air supply for supplying the valve arrangement and the compressed-air outlets with compressed air from a compressor and/or a compressed-air reservoir;
• wherein
• the bistable valve is supplied with compressed air by the compressed-air supply on the inlet side irrespective of the switching status of the valve arrangement, said compressed air being at a pressure which is provided by the compressor and/or the compressed-air supply,
• the first solenoid valve is supplied with compressed air by the compressed-air supply on the inlet side,
• the second solenoid valve is between the first solenoid valve and at least one of the at least two compressed-air outlets,
• the third valve is arranged to control of supply of compressed air to at least one of the two compressed-air outlets,
• a first inlet of the first select high valve is connected to an outlet of the bi-stable valve and a second inlet of the first select high valve is connected to a line between the first solenoid valve and the second solenoid valve,
• an outlet of the first select high valve is connected to a control inlet of the third valve,
• one of the at least two compressed-air outlets supplies an emergency-brake connection with compressed air, wherein a relay valve is connected upstream of the one compressed-air outlet, and
• at least one pressure sensor for measuring the pressure of the compressed air is arranged within the valve arrangement.
