The present invention relates to an eco-friendly vehicle, and a motor torque control method of the same. The present invention determines a road characteristic based on a wheel behavior characteristic when acceleration control of the eco-friendly vehicle having a motor and controls torque of the motor to at least minimize wheel spin or prevent the wheel spin during the acceleration of the vehicle based on a determination result of the road characteristic. To this end, according to the present invention, the method comprises: a step of determining the wheel behavior characteristic of the vehicle; a step of determining the road characteristic of a road where the vehicle is positioned based on the wheel behavior characteristic of the vehicle; and a step of controlling the torque of the motor of the vehicle based on the road characteristic.
본 발명은 친환경 차량 및 그 모터 토크 제어 방법에 관한 것으로, 모터를 구비한 친환경 차량의 발진 제어 시 휠 거동 특성에 기초하여 노면 특성을 판별하고, 노면 특성 판별 결과에 기초하여 차량 발진 시 휠 스핀이 발생하지 않도록 또는 적어도 휠 스핀을 최소화하도록 모터의 토크를 제어하는데 그 목적 있다. 이를 위해 본 발명에 따른 친환경 차량의 모터 토크 제어 방법은, 차량의 휠 거동 특성을 판별하는 단계와; 상기 차량의 휠 거동 특성에 기초하여 상기 차량이 위치한 도로의 노면 특성을 판별하는 단계와; 상기 노면 특성에 기초하여 상기 차량의 모터의 토크를 제어하는 단계를 포함한다.
