Patent abstract

A control system for a adjustable damping force damper includes a damper and a spring provided on a suspension apparatus of a vehicle, a sprung speed sensor for detecting speed of an upper member of the spring, the sprung speed is generated when the vehicle gets over steps on a road surface and a control unit for setting a gain so as to determine an damping force of the damper based on a product of the sprung speed and the gain. When an absolute value of the sprung speed exceeds a predetermined value, the control unit changes the gain in response to a positive sign or a negative sign of the sprung speed.
