Compressed air supply system for vehicle compressed air installation and process for controlling said system

A process for controlling a compressed air supply device (10.1) for vehicle compressed air systems which comprises controlling a control electronics (57) for controlling the compressed air supply of the compressed air supply system as a function of pressure in at least two compressed air consumer circuits,

• monitoring the pressure by the control electronics (57) in at least two consumer circuits, operating the control electronics (57) to disconnect the consumer circuits from the compressed air supply as a function of a pre-programmed limit pressure that depends on the circuit,
• operating the control electronics (57) to connect at least two respective consumer circuits to the compressed air supply when the pressure falls below a limit pressure by a pre-programmed pressure difference, which comprises operating the control electronics (57) to select a consumer circuit for filling said consumer circuit with compressed air while at least one other consumer circuit is disconnected from the filling, and operating the control electronics (57) to connect the consumer circuit to the compressed air supply of the air supply system in a pre-programmed order.
