A damping apparatus for an automobile is provided, capable of ensuring a high level of reliability while obtaining excellent damping effect with simple configuration. The damping apparatus for an automobile that reduces vibrations of an automobile body may include an actuator that is attached to the automobile body and drives an auxiliary mass; a current detector that detects a current flowing through an armature of the actuator; a section that detects a terminal voltage applied to the actuator; a calculation circuit that calculates an induced voltage of the actuator, and further calculates at least one of the relative velocity, relative displacement, and relative acceleration of the actuator, based on a current detected by the current detector and the terminal voltage; and a control circuit that drive-controls the actuator based on at least one of the relative velocity, relative displacement, and relative acceleration of the actuator calculated by the calculation circuit.

Wind power can be always detected even when a wind turbine 11 forcibly brakes, as well as cost of components can be reduced. A generator includes a wind turbine 11 rotated by wind power to generate a driving force, a dynamo 19 operated by the driving force of the wind turbine 11 to generate electricity, a short-circuit brake 21 for switching the output side of the dynamo 19 between an output state and a short-circuit state, a rotational speed input unit 41 or an arithmetic processing part 51 for recognizing the magnitude of the wind power in both of the output and short-circuit states based on the rotational speeds of the wind turbine 11 in both of the output and short-circuit states, and an arithmetic processing part 51 for determining which state the dynamo 19 should be changed over to between the output and short-circuit states based on the rotational speed of the wind turbine 11 and controlling the switching of the short-circuit brake 21 based on the determination result.

An automobile vibration damping device for an automobile in which a power plant in which an engine, a transmission and the like are combined is supported by a vehicle body, including a vibrating means that generates vibration separate from vibration of the engine. Thereby, it is possible to reduce the vibration amplitude of a seat portion by the reaction force of the vibrating means. Also, if the vibration mode of the vehicle body is adjusted so as to become a node in the vicinity of the seat portion, the vibration amplitude decreases in the vicinity of the seat portion, and improves riding comfort.
