Method for controlling the level of an air-suspended motor vehicle

The invention relates to a method for controlling the level of an air-suspended motor vehicle (50) that comprises an air-suspended front axle (60) and at least one air-suspended rear axle (70). In said method, by means of level-adjustment valves (15, 16, 17, 18) in the form of control valves, a plurality of air-spring bellows (2, 3, 6, 7) arranged between chassis suspension elements of the vehicle axles (60, 70) and the vehicle body (80, 80') are each supplied with air whenever a lower tolerance limit (xT_u) of a tolerance band (delta x T) is not reached, and air is released from said bellows whenever an upper tolerance limit (xT_o) of the tolerance band (delta x T) is exceeded, in order to control a predetermined target level (xsoll). When in a particular operational state, at least one of said two tolerance limits (xT_u, xT_o) is modified in a suitable manner for at least one air-spring bellows (2, 3, 6, 7) of at least one vehicle axle (60, 70) or one vehicle side (53, 54). In order to reduce the period req
