Damping apparatus for reducing vibration of automobile body

摘要

An object of the present invention is to provide a damping apparatus for an automobile, capable of ensuring a high level of reliability while obtaining an excellent damping effect with a simple configuration. The damping apparatus for an automobile that reduces vibrations of an automobile body, includes: 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.
