Abstract
In a motor vehicle having a vehicle height adjusting device, wherein the height of each suspension is controlled so as to attain a set reference vehicle height, reaction forces of respective suspensions are detected and a difference between the detected reaction forces is calculated according to a formula, while the vehicle is stationary or is being driven straight. When the difference exceeds a predetermined value, it is determined that there are imbalances of the road surface contact loads of the wheels. Upon the determination of imbalances, the reference vehicle height is increased for some suspensions and decreased for other suspensions to eliminate the imbalances. The determination of imbalances is made when a value given by a formula including the integrated values for the suspensions exceeds a predetermined value, and then reference vehicle height is increased and decreased for the suspensions to eliminate the imbalances.
