Title: Method for establishing a rate limit on the damper command signal of a vehicle damper

Abstract: A first method of the invention is for establishing a limit on the time rate of change of a damper command signal applied to a damper associated with a wheel of a vehicle, wherein the damper has damping characteristics, wherein a change in the damper command signal changes the damping characteristics, and wherein the damper command signal is derived at least from an algorithm for vehicle body control. The first method includes steps a) through c). Step a) includes identifying a noise indicating signal predictive of noise occurring in the vehicle due to operation of the damper, wherein the noise indicating signal is derived from the algorithm. Step b) includes calculating the noise indicating signal. Step c) includes determining the limit based at least on the calculated noise indicating signal.
