摘要： In a suspension controller 15 comprising a damper (12, 20) having a valve 46 switchable at frequencies within a desired activation frequency range between high and low damping modes, an unfiltered damper signal 120 is repeatedly derived from vehicle suspension related variables at a rate significantly greater than the desired activation frequency range. An output filter derives a filtered damper signal 130 from each successive binary actuator force signal by (1) resetting a timer each time the unfiltered damper signal 120 changes value, (2) causing the filtered damper signal 130 to be the same value as the unfiltered damper signal 120 if the time elapsed from the reset time has reached or exceeded a predetermined length, and (3) maintaining the filtered damper signal value unchanged if the time elapsed has not reached the predetermined length. The damper (12, 20) is controlled in response to the filtered damper signal 130, whereby unnecessary high frequency switching of the valve is reduced but the damper (12, 20) responds without unnecessary delay to signals within the desired activation frequency range.
