Patent ID: 8521361

Claim:
A method of controlling a suspension system between a sprung mass and an unsprung mass in a vehicle, the method comprising: receiving data representing a target ride height, an actual position between the sprung mass and the unsprung mass at each of a plurality of wheel locations of the vehicle, an actual force parameter related to an actual force applied to the sprung mass at each of the plurality of wheel locations of the vehicle; determining by a ride height control system, a level condition target ride height (TRH) force parameter related to a target force to be applied to the sprung mass at each of the plurality of wheel locations of the vehicle if the vehicle were at the target ride height on a relatively level surface, the level condition TRH force parameter being based, at least in part, on a desired force distribution at the wheel locations; determining by a ride height control system, a current condition target force parameter related to a target force to be applied to the sprung mass at each of the plurality of wheel locations of the vehicle by transforming the level condition TRH force parameter determined for each of the wheel locations to a current non-level condition, the current condition target force parameter at a respective one of the wheel locations being based, at least in part, on the level condition TRH force parameter, the target ride height, and the actual position for the respective one of the wheel locations; and providing at least one suspension system control signal to the suspension system in response to the current condition target force parameter determined for each of the wheel locations.
