  "textContent": "A damping control apparatus has a control unit that controls an active actuator that generates a control force to damp a sprung, and a storage device for storing a unsprung displacement acquired based on a vertical motion state quantity of a vehicle when the vehicle travels, and the control unit determines a predicted wheel passage position where a wheel is predicted to pass, calculates a time derivative value of an unsprung displacement at the predicted wheel passage position acquired by a preview sensor, calculates a target control force based on a sum of a first control component proportional to the time derivative value and a second control component proportional to an unsprung displacement at the predicted wheel passage position acquired from the storage device, and controls a control force generating device so that a control force when the wheel passes the predicted wheel passage position becomes the target control force.",
