Original Abstract Submitted

An actuator of a suspension control system is controlled by a control device to adjust a suspension stroke of a controlled wheel of a vehicle. In the control device, a first acquisition unit repeatedly acquires a road surface displacement-related value from a road surface data map. A second acquisition unit acquires a change amount of the road surface displacement-related value per unit time. A control unit controls the actuator so that a control force generated by the actuator when the controlled wheel passes through a predicted passing position matches a target control force. When the change amount of the road surface displacement-related value per unit time is not less than a threshold value, a calculation unit calculates the target control force so that the change amount of the target control force per unit time becomes smaller than that when the amount of change is less than the threshold value.
