Abstract

A method for controlling the level of an air-suspended motor vehicle includes determining, by a sensor system, at least one of the speed of travel or the actuation state of a parking brake, measuring, if at least one of the speed of travel has undershot a minimum speed of travelor the parking brake has been actuated, the actual level in the region of each air spring bellows, comparing the measured values for the actual level with the predetermined setpoint level, determining an actual level value of an air spring bellows having the greatest deviation from the setpoint level, and expanding, for the air spring bellows having an actual level having the greatest deviation from the setpoint level, the tolerance band by at least one of increasing the upper tolerance limit thereof to a corrected upper tolerance limit or lowering the lower tolerance limit thereof to a corrected lower tolerance limit.
