ABSTRACT:
A suspension control system for use with shock absorbers provided between sprung and unsprung masses of an automotive vehicle at the positions of the respective vehicle road wheels for providing variable damping force characteristics. The suspension control system includes sensors mounted on the vehicle for sensing sprung mass vertical accelerations acting in a predetermined direction with respect to the vehicle at the respective road wheel positions. A component of the vehicle longitudinal acceleration acting in the predetermined direction is calculated as a function of vehicle pitching angle and vehicle longitudinal acceleration. The sensed sprung mass vertical accelerations are corrected in a direction to cancel the calculated vehicle longitudinal acceleration component. The shock absorbers are controlled based on the respective corrected sprung mass vertical accelerations.
