ABSTRACT:
In a suspension system which is designed to maintain a nominal ride height between the body and the unsprung parts of a vehicle, the difference in wheel speed on opposite sides of the vehicle produced during cornering is used to inhibit adjustment of ride height.
An electrical sensor and control unit is used to control flow of hydraulic fluid to and from a suspension unit by means of solenoid-operated valves, so as to maintain the ride height constant. A cornering sensor compares the sensed speeds of two wheels, preferably mounted on a common axle, and inhibits the control unit when the difference in speeds departs from an expected difference by more than a certain amount. The expected difference may be zero or it may be the average difference derived over a period of time.
