본 발명은 하이브리드 차량의 진동 추출 장치에 관한 것으로, 구체적으로 목표 진동 주파수를 가변하여 엔진의 진동을 추출할 수 있는 하이브리드 차량의 진동 추출 장치 및 방법에 관한 것이다. 이를 위해, 본 발명의 일 실시 예에 따른 하이브리드 차량의 진동 추출 장치는 동력원인 엔진과 구동모터; 상기 엔진과 연결되는 시동 발전기; 및 상기 시동 발전기의 모터 속도를 설정하고, 상기 모터 속도를 이용하여 속도 변동량을 생성하며, 상기 속도 변동량이 기준값을 초과하면 엔진의 진동 주파수를 연산하고, 상기 엔진의 진동 주파수에 따른 필터 대역을 설정하며, 상기 필터 대역을 통해 엔진의 진동을 추출하는 제어기를 포함한다.

    The present disclosure relates to an apparatus for extracting vibration of a hybrid vehicle, and more particularly, to an apparatus and a method of extracting vibration of a hybrid vehicle by varying a target vibration frequency. An apparatus for extracting vibration of a hybrid electric vehicle includes: an engine and a driving motor, which are power sources; a starter motor/generator connected to the engine; and a control unit configured to measure a motor speed of the starter motor/generator, to generate a speed variation quantity based on the motor speed of the starter motor/generator, to calculate a vibration frequency of the engine when the speed variation quantity exceeds a reference value, to set a filter band based on the vibration frequency of the engine, and to extract, with the filter band, a vibration of the engine.
