본 발명의 일 실시예에 따른 전기차 험로 탈출 장치는 스티어링 휠을 회전하면서 구동 토크를 인가하여 최대 견인력 발생 조향각을 찾고, 스티어링 휠을 상기 최대 견인력 발생 조향각 만큼 회전한 후 가할 수 있는 최대 휠 토크를 확인하는 최대 견인력 확인부; 다양한 피칭(pitching) 모션이 구현된 차량의 전륜과 후륜에 가해지는 축중량을 반복 산정하는 축중량 연산부; 및 상기 최대 견인력 확인부와 상기 축중량 연산부에서 정보를 수신 받고, 차량의 탈출을 제어하는 발진 제어부;를 포함할 수 있다.
An apparatus for escaping an uneven driving surface for an electric vehicle includes a maximum traction identification portion configured to search for a steering angle at which maximum traction is generated by applying driving torque while rotating the steering wheel. The maximum traction identification portion is also configured to identify maximum wheel torque able to be applied after rotating the steering wheel by the steering angle at which maximum traction is generated. The apparatus also includes an axle weight computation portion configured to repeatedly calculate an axle weight applied to front and rear wheels of a vehicle in which various pitching motions are implemented. The apparatus also includes a driveaway controller configured to receive information from the maximum traction identification portion and the axle weight computation portion and to control escape of the vehicle.
