ABSTRACT:
A method of controlling a vehicle suspension system including a real time continuously variable damper comprising the steps of: (a) determining a present actuator command for controlling damping force of the damper; (b) comparing the present actuator command to a previous actuator command to determine a difference value of the actuator commands; (c) if the difference value is positive, limiting the difference value to a positive threshold; (d) if the difference value is negative, limiting the difference value to a negative threshold, wherein the negative threshold has a magnitude greater than a magnitude of the positive threshold; (e) determining an output actuator command responsive to the difference value; and (f) outputting the output actuator command to the damper to control damper force, wherein the limiting of the difference value to the positive threshold reduces suspension harshness and audible noise and wherein the limiting of the difference value to the negative threshold reduces suspension audible noise.
