ABSTRACT:
A suspension control system for a motor vehicle, includes a vertical accelerating detector for detecting a vertical acceleration of a vehicle body; a damping force changing device for switching suspension damping forces for the front and rear wheels of the vehicle body at least in three steps; a vertical acceleration differential value measuring device for measuring a differential value of an output signal of the vertical acceleration detector; and a damping force hold determining device for setting, according to an output of the vertical acceleration differential value measuring device, damping forces for the front and rear wheels to soft level simultaneously or setting damping forces for the rear wheels only to soft level and maintaining the damping forces.
