Abstract:
1. A control device for controlling a variable damper of a vehicle suspension system, comprising: at least one sensor for detecting a dynamic state of a vehicle and a stroke sensor for detecting a movement of the damper; a target damping force determining unit for computing a target damping force of a vehicle, the target damping force being selectively directed in one of a contracting direction and an extending direction of a movement of the damper; and a control value determining unit for computing by a processor a control value of the damper according to the target damping force determined by the target damping force determining unit and a stroke speed detected by the stroke sensor, wherein the target damping force is determined by a same control value without regard to the direction of the movement of the damper when the stroke speed of the damper is within a range including a zero stroke speed.
