The present invention relates to a motor torque control method when a resolver offset of an electric vehicle is corrected. More specifically, the purpose of the present invention is to provide the motor torque control method when the resolver offset of the electric vehicle is corrected to improve the sense of difference a driver feels through a motor torque control when the resolver offset of the electric vehicle is corrected during driving. Therefore, the present invention provides the motor torque control method when the resolver offset of the electric vehicle is corrected the driver is capable of discriminating and controlling the motor torque of a (-) torque area and motor torque of a (+) torque area after controlling the motor torque as 0 for a period by setting to an offset correction mode for resolver offset correction in a tip out state of accelerator pedal when a request of the resolver offset correction of a vehicle is made while driving.

    본 발명은 전기자동차의 레졸버 옵셋 보정시 모터 토크 제어 방법에 관한 것으로, 더욱 상세하게는 주행중 레졸버의 옵셋 보정시 모터 토크 제어를 통해 운전자가 느끼는 이질감을 개선하기 위한 전기자동차의 레졸버 옵셋 보정시 모터 토크 제어 방법을 제공하는데 목적이 있다. 이에 본 발명에서는, 주행중인 차량의 레졸버 옵셋 보정의 요청이 발생하면 엑셀페달의 팁 아웃 상태에서 레졸버 옵셋 보정을 위한 옵셋 보정 모드로 진입하여 모터 토크를 일정시간 동안 0으로 제어한 뒤 (-)토크 영역의 모터 토크를 (+)토크 영역의 모터 토크와 차별화하여 제어하는 것을 특징으로 하는 전기자동차의 레졸버 옵셋 보정시 모터 토크 제어 방법을 제공한다.
