  "textContent": "To eliminate unsprung tramp sensations and feelings of hardness when the stroke speed decreases in a conventional skyhook control. The present invention comprises a control device configured to apply, to a variable damping force damper, a target control force determined based on a damping coefficient of the variable damping force damper in a suspension mechanism. 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. In addition, in the case of a first condition, the control device determines a target control force based on a damping coefficient held in advance.",
