Claims (1)
による車体振動の周波数で作られた加振信号を、上記車
体振動の節を車室内に移動させるべくエンジン回転数に
基づき移相及びゲイン調整を行なって上記加振機に供給
する制御手段とを有する車体振動低減装置において、上
記エンジン回転数の変動幅が一定値以上の場合加振機を
作動させないように制御手段を有することを特徴とする
車体振動低減装置。 ・[Scope of Claim for Utility Model Registration] A vibrator that is attached to the vehicle body and generates vibrations, and an excitation signal generated at the frequency of the vehicle body vibrations caused by the engine, which is connected to the engine in order to move the nodes of the vehicle body vibrations into the vehicle interior. In a vehicle body vibration reduction device having a control means that performs phase shift and gain adjustment based on the engine speed and supplies the result to the vibration exciter, the vibration exciter is prevented from operating when the fluctuation range of the engine speed exceeds a certain value. A vehicle body vibration reduction device comprising a control means.・
