본 발명은 친환경 차량의 레졸버 옵셋 보정 장치, 그를 포함한 시스템 및 그 방법에 관한 것으로, 본 발명의 실시예에 따른 레졸버 옵셋 보정 장치는 엔진 클러치 해제 여부 및 모터 토크 지령을 판단하여 레졸버 옵셋 보정 오차 여부를 판단하는 레졸버 옵셋 보정 오차 판단부; 상기 레졸버 옵셋 보정 오차가 발생한 것으로 판단되면 모터 속도 변화값을 산출하는 모터 속도 변화값 산출부; 및 상기 모터 속도 변화에 대한 레졸버 옵셋 변동치 테이블을 이용하여 레졸버 옵셋 변동치를 추출하는 제어부;를 포함할 수 있다.

    The present disclosure relates to an apparatus for correcting an offset of a resolver of an environment-friendly vehicle. The apparatus includes a resolver offset correcting error determining unit configured to determine whether a resolver offset correction error occurs, by determining whether an engine clutch is released and a torque command of a motor. The apparatus further includes a motor speed change value calculating unit configured to calculate a change value of a speed of the motor when it is determined that the resolver offset correction error occurs and a controller configured to extract a resolver offset change value by using a resolve offset change value table for the change value of the speed of the motor.
