ABSTRACT:
A motor vehicle suspension system includes rear suspension units to adjust ride height between sprung and unsprung parts of the vehicle, control means for monitoring and maintaining ride height at a particular setting and wheel speed monitoring means for monitoring wheel speeds. The control means provides a corrective up height change signal in the event of an unrequested height change and there existed before the unrequested height change a wheel speed signal indicative of vehicle movement. The corrective height change signal may be applied to each suspension unit or the control means may monitor abnormal vehicle activity and provide the corrective height change signal to the appropriate suspension unit. One example of abnormal vehicle activity is when the wheel speeds differ significantly, the control means responding to provide the corrective height change signal to the suspensions unit on the side of the vehicle with the highest wheel speed. A second example of abnormal vehicle activity is where the suspension units use fluid pressure to support the vehicle and a difference in pressures before and after the unrequested height change is used to provide the corrective height change signal to the suspension unit on the side of the vehicle with the lowest suspension pressure.
