Abstract
A device and method controls the different energy sources for supplying a vehicle with main and auxiliary air, for which compressed air is produced for pressurizing a main air tank and an auxiliary air tank using at least one compressor. That compressor is driven via a respective associated electric motor, wherein the main air is supplied via an external primary energy source and the auxiliary air is supplied at least partially via an internal secondary energy source which is weaker in contrast. There is a shift between the two different energy sources depending on the operating status of the vehicle, wherein the auxiliary air supply is switched off by decoupling the electric motor from the secondary energy source.
