ABSTRACT:
A vehicle height control system includes a plurality of vehicle height adjusters actuated by a pneumatic 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. The control unit compares the target differences for respective vehicle height adjusters, and the adjuster having the target difference which is the largest in magnitude is first actuated to perform its adjusting operation, thereby preventing unbalanced differences in the vehicle height.
