==Original Abstract Submitted==

A suspension system includes: a variable damper configured to use a damping force variable actuator to adjust communication of working fluid generated in a passage by a relative movement between a vehicle body and a wheel, to thereby adjust a damping force over a range of a soft characteristic to a hard characteristic; and a controller configured to control the damping force variable actuator. The variable damper further includes a frequency response unit configured to reduce the damping force for vibration at a specific frequency. The controller is configured to increase a change rate from a soft side to a hard side at a time of controlling the damping force to reach a target damping force when a frequency of the relative movement between the vehicle body and the wheel is lower than a first frequency set to the frequency response unit.
