Abstract
A suspension control system for an automotive vehicle is disclosed in which, in each shock absorber, interposed between the vehicular body and tire wheel, a damping coefficient varying adjuster is provided which changes a damping coefficient at either or both of piston stroke sides according to a control signal input thereto so that the damping coefficient is set to a target damping coefficient position, at lease one sprung mass acceleration sensor and at least one sprung mass speed sensor are provided, and the control unit is provided which outputs the control signal to the damping coefficient varying means according to a result of determination of whether the vertical sprung mass acceleration exceeds a predetermined threshold value and according to a direction and magnitude of the sprung mass speed so that the damping coefficient at either or both of the stroke sides is controlled to a target damping coefficient position.
