본 발명은 서스펜션의 댐퍼가 작동할 때 발생되는 진동이 실내로 유입되어 나타나는 구조 전달 소음을 저감시키기 위한 자동차 서스펜션의 노이즈 저감 시스템에 관한 것으로, 서스펜션 댐퍼에 장착되는 진동 감지부, 서스펜션 댐퍼가 장착되는 차체의 탑 마운트부에 장착되어 댐퍼 작동시 발생되는 진동과 반대 위상의 진동을 발생시켜 탑 마운트부로 가진하는 역 위상 진동 발생부, 및 진동 감지부에서 감지된 측정값을 전달받아 목표 역 위상 진동을 계산하고 역 위상 진동 발생부를 제어하는 제어부를 포함한다.

    The present disclosure relates to a noise reduction system for an automobile suspension for reducing structurally transmitted noise caused by vibrations generated when a damper of the suspension operates and entering the interior of the automobile. The noise reduction system comprises: a vibration detection unit that is mounted on the suspension damper; an anti-phase vibration generator that is mounted on a top mount portion of a vehicle body on which the suspension damper is mounted and generates vibration in an opposite phase to vibration generated when the damper operates to be applied to the top mount portion; and a control unit that receives a measurement value detected by the vibration detection unit, calculates a target anti-phase vibration, and controls the anti-phase vibration generator.
