A control device applies a target control force to a variable damping force damper in a suspension mechanism based on a damping coefficient of the variable damping force damper to eliminate unsprung tramp sensations and feelings of hardness when the stroke speed decreases in a conventional skyhook control. The control device includes a state estimation unit for calculating the sprung mass speed of the sprung mass based on a value detected by several of a plurality of sensors, an application control unit for calculating and outputting a damping coefficient of the variable damping force damper based on the calculated sprung mass speed, and a target control amount management unit for determining the target control force based on the damping coefficient output by the application control unit.
