Abstract

A level control system for a vehicle includes a pressure generator (10) for generating a pressure difference between a reservoir (11) containing a pressurized medium and at least one pressure-controlled actuating mechanism (12i) in order to adjust a predefined vehicle chassis level (di,soll), and a valve unit (13) for performing an overflow process between the reservoir (11) containing the pressurized medium and the at least one pressure-controlled actuating mechanism (12i). An evaluation unit (24) decides whether and to what extent the predefined vehicle chassis level (di, soll) can be adjusted by exclusively actuating the valve unit (13) based on a vehicle chassis level (di,erw) that is to be expected in case the overflow process is performed.
