Abstract
A vehicle height control system includes a plurality of vehicle height adjusters actuated by a hydropneumatic actuating system and controlled respectively by control signals from a control unit. The control unit calculates, for each of the vehicle height adjusters, a target difference between a target adjustment position and an actual position detected by a vehicle height sensor associated with the adjuster. A maximum target difference is selected from the target differences respectively for the adjusters, and the selected maximum target difference is divided by a predetermined adjusting unit to determine a number of steps for adjustment of the target difference a little amount at a time. Then, tentative- or pseudo-target adjustment positions ranging between the actual position and the target adjustment position are obtained for each adjuster, and the adjustment control of each adjuster is carried out to achieve the pseudo target adjustment positions step by step.
