摘要： An apparatus and method for controlling damping force characteristics of respective vehicular shock absorbers in which vehicular vertical behavior(s) at the position(s) of the vehicular body which are forward by a predetermined distance from a tread of rear left and right road wheels are determined, the positions including front left and right road wheel sides, and corresponding vertical behavior signals are derived. Control signals for front left and right and rear left and right road wheel side shock absorbers are formed on the basis of respective processed signals having frequency-dependent characteristics formed from the vehicular behavior signal(s). The damping force characteristics of front left and right road wheel side shock absorbers are controlled on the basis of the control signals formed on the basis of the processed signal based on the front left and right road wheel vehicular behavior signals. Those of rear left and right road wheel side shock absorbers are controlled on the basis of the control signals formed on the basis of the processed signals based on the front position vehicular vertical behavior signal at the position forward from the tread between the rear left and right road wheels. The phases of the control signals V are generally matched with vehicular behavior velocity signals which would actually be generated at rear road wheel arranged positions of the vehicle.

摘要： 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.
