Patent ID: 8761999

Claim:
A level control system for a vehicle, having a pressure generator ( 10 ) for generating a pressure difference between a pressure medium reservoir ( 11 ) and at least one pressure-controlled actuating device ( 12 i ) by means of which it is possible to set a prescribed vehicle body level (d i,soll ), and having a valve device ( 13 ) for carrying out an overflow process between the pressure medium reservoir ( 11 ) and the at least one pressure-controlled actuating device ( 12 i ), wherein an evaluation unit ( 24 ) decides on the basis of an initial vehicle body level (d i,erw ) to be expected for the case of carrying out the overflow process whether and to what extent it is possible to set the prescribed vehicle body level (d i,soll ) solely by actuating the valve device ( 13 ), wherein the evaluation unit generates the prescribed vehicle body level based on vehicle speed and the initial and prescribed vehicle body levels represent respective displacements of the at least one pressure-controlled actuating device ( 21 i ) and wherein the evaluation unit estimates a gas quantity necessary to effect a height change from the initial vehicle body level to the prescribed vehicle body level and operates the pressure generator based on the gas quantity.
