Abstract
A method of controlling a suspension system for a vehicle which comprises determining a first filter vehicle height based upon a signal from at least one sensor located at a rear axle of the vehicle at a first time. A second filter vehicle height is determined based upon a signal from the at least one sensor located at the rear axle of the vehicle at a second time. The difference between the first filter signal and the second filter signal is compared to a forklift threshold and the suspension system is placed in forklift mode when the difference between the first filter signal and the second filter signal exceeds the forklift threshold.
