Abstract
A suspension control system for enhancing the response characteristic of a vehicle body vibration suppressing control by lowering the spring constant or the damping force to a first desired level for both front and rear wheels at a time or only the rear wheel for a predetermined time in accordance with a differential value of an output signal from an acceleration detecting means in the vertical direction of the vehicle body, to thereby soften the shock of the vehicle body when the rear wheels get over a protuberance, and also by changing the spring constant or the damping force settled beforehand to a second desired level for both front and rear wheels at a time in case an unnecessary vibration of the vehicle body is detected afterwards. The second desired level is held for a predetermined time or continuously to suppress vertical vibrations of the vehicle body.
