The present invention provides a controlling method of a motor torque for an electric vehicle which improves so that a motor torque does not suddenly change when a regenerative braking torque demand amount is changed into a creep torque. The motor torque controlling method for an electric vehicle comprises: a step (a) of determining a driving state of a vehicle; a step (b) of determining whether a predetermined creep torque raising rate limiting condition is satisfied when satisfying a deceleration driving condition of the vehicle; and a step (c) of applying the creep torque by limiting the raising rate, when satisfying the creep torque raising rate limiting condition.
본 발명은, 전기 차량용 모터 토크 제어 방법에 관한 것으로서, (a) 차량의 주행 상태를 판단하는 단계; (b) 차량의 감속 주행 조건이 만족된 경우에, 미리 정해진 크립 토크 상승율 제한 조건이 만족되었는지 판단하는 단계; 및 (c) 상기 크립 토크 상승율 제한 조건이 만족된 경우에, 크립 토크를 상승율을 제한하여 적용하는 단계를 포함한다.
