A method of controlling an air compressor of a vehicle. The absolute humidity is determined for atmospheric air entering the compressor as well as for the compressed air exiting the compressor. A liquid water mass formed or evaporated inside the compressor during a defined period of time is calculated. The above steps are repeated in order to calculate a cumulated liquid water mass inside the compressor. The compressor is stopped when the calculated cumulated liquid water mass has returned to zero and the control unit no longer receives a compressed air request.

Method for venting a pneumatic system of a vehicle, pneumatic system and vehicle Method for venting a pneumatic system () of a vehicle, the pneumatic system () comprising an air compressor (), a pneumatic circuit (), an air pressure management system () in communication with the air compressor () and the pneumatic circuit (), and a control unit, the method comprising: —while pressure in the pneumatic circuit () is less than a cut-out pressure, supplying the pneumatic circuit () with compressed air from the air compressor () operated at an operating speed through the air pressure management system (), —once pressure in the pneumatic circuit () reaches the cut-out pressure, lowering pressure in the pneumatic circuit () to a target pressure, the air compressor () being operated at at least one deflating speed lower than the operating speed, the deflating speed being non null, —after pressure in the pneumatic circuit () has reached the cut-out pressure, releasing compressed air in the air pressure management system () to the outside environment.
