Suspension control adjusting vehicle height

摘要

The height of each suspension is controlled so as to attain a set reference vehicle height (H). Reaction forces (PFL, PFR, PRL, PRR) of respective suspensions (1a,1b,1c,1d) are detected and a difference (delta P) 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
