Abstract
A suspension control system for an automotive vehicle is disclosed in which a band pass filter is provided which passes only a frequency component of either of a vertical sprung mass acceleration signal derived from a vertical G sensor or a vertical sprung mass speed signal derived from an integrator which integrates the vertical sprung mass acceleration signal, both vertical acceleration sprung mass speed signal and vertical sprung mass speed signal falling in a predetermined frequency range (e.g., 0.5 Hz through 3.0 Hz). A control unit outputs a control signal to an actuator so to vary the position of an adjuster of each or any one of shock absorbers, thus a damping coefficient being set to a target damping coefficient position according to the vertical sprung mass speed.
