Abstract
Disclosed is a pneumatic level control system equalizer of a motor vehicle equipped with a battery and a generator supplying the battery, as well as a compressor driven by an electric motor and associated with the level control system equalizer, the electric motor of the compressor being only supplied with electric current by the vehicle battery and/or generator in certain conditions. The power requirements of the level control system equalizer can be pre-evaluated for a change of level and/or a filling of the pressure tank to be performed.

18. A pneumatic level control method for a motor vehicle (10) having a vehicle battery (44) and a generator (46) supplying the vehicle battery (44), and an electrically operated compressor (18) with an electric motor (16), which compressor is assigned to the level control system (12), the electric motor (16) of the compressor (18) being supplied with power by the vehicle battery (44) and/or the generator (46) only under certain conditions, the method comprising the steps of
determining in advance an energy requirement of the level control system (12) for at least one pending operation, determining a current energy status of the battery determining a first threshold value of the energy status, determining the energy status of the battery after performing the at least one pending operation, determining that the energy status after performing the at least one pending operation exceeds the first threshold value and performing the at least one pending operation by the pneumatic level control system (12).
