摘要： A suspension system control according to the steps of: determining an actuator demand force command; determining, responsive to vehicle speed, a first signal indicative of a first maximum demand force; determining, responsive to ambient temperature, a second signal indicative of a second maximum demand force; and constraining the determined actuator demand force command so that it is no greater than the lesser of the first and second maximum demand forces, wherein vehicle body isolation from suspension events is maintained during low temperature and low speed operation of the vehicle to thereby minimize suspension noise and ride harshness.
