ABSTRACT:
A vehicle height control system includes a plurality of vehicle height adjusters actuated by a hydropneumatic actuating system and controlled 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 set by a setting device and an actual position detected by a vehicle height sensor associated with the adjuster, and the control unit generates the control signals in accordance with the respective target differences. The control unit further selects a maximum target difference, and calculates deviations of the target differences from the maximum target difference. When any of the deviations exceeds a predetermined value, the adjustment operation of the vehicle height adjuster associated with this deviation is temporarily stopped thereby correcting the nonuniformity of the adjustments in the vehicle height adjusters.
