A compressed air supply system for a utility vehicle includes a compressor that can be driven by a drive by a pneumatic clutch, and a valve that can be actuated by an electrical signal for the selective supply of compressed air to a control input of the clutch. The electrical signal is provided by an electronic control system to which signals indicating an operating state of a compressed air preparation system and various vehicle states can be supplied.
