<p>A suspension control system for controlling at lease one shock absorber provided between sprung and unsprung masses of an automotive vehicle to provide a variable damping force characteristic. The control system includes a low pass filter for filtering out noise superimposed on an electric signal indicative of a sensed steering angle. The noise removed steering angle indicative signal is fed to a control unit operable in a normal control mode for controlling the shock absorber based on a sensed vehicle behavior to provide an optimum damping force characteristic and in a roll control mode for controlling the shock absorber based on the noise removed vehicle steering angle indicative signal to provide a damping force characteristic greater than that provided in the normal control mode. The control unit operates in the roll control mode when the noise removed steering angle indicative signal exceeds a predetermined first threshold value. The operation is changed from the roll control mode to the normal control mode a predetermined time after the noise removed steering angle indicative signal decreases below a second threshold value set in direct proportion with a peak value of the noise removed steering angle indicative signal. <IMAGE></p> |
