Abstract
A vehicle damper including an electromagnetic damper configured to generate a damping force with respect to a motion of a sprung portion and an unsprung portion toward each other and a motion thereof away from each other and includes: an electromagnetic motor; a motion converting mechanism; and an external circuit which is disposed outside the electromagnetic motor and including a first connection passage and a second connection passage and which includes a battery-device connection circuit for connecting the motor and a battery device and a battery-device-connection-circuit-current adjuster configured to adjust an electric current that flows in the battery-device connection circuit, wherein the damper system further includes an external-circuit controller configured to control an electric current that flows in the electromagnetic motor by controlling the external circuit and configured to control a flow of an electric current between the battery device and the electromagnetic motor by controlling the battery-device-connection-circuit-current adjuster.
