The present invention relates to a truck and a control method of a drive motor for driving mounted on a truck capable of easily starting on a hill by an easy method. If a stepping amount of an accelerator pedal is 0%, torque Ta is generated when a revolution number is 0. If a retreat occurs when starting on the hill, the revolution number decreases. If the revolution decreases, the torque increases. As a result, the power of the retreat balances with a driving force and then the retreat converges to movement at a constant velocity. Therefore, a weight of a car is not necessary to determine the torque. The truck comprises: a drive motor for driving; and a control device generating the torque of the absolute value, equivalent to the absolute value of the torque in accordance with a hill gradient, on the drive motor.

    액셀러레이터 페달의 답입량이 0%인 경우, 회전수가 0일 때 토크 Ta가 발생한다. 비탈길 발진에 있어서 후퇴가 발생한 경우, 회전수가 감소한다. 회전수가 감소하면 토크는 증대된다. 이 때문에 결과적으로 후퇴력과 추진력이 균형을 이룬다. 이 결과, 후퇴는 결국에 등속 운동에 수렴한다. 이와 같이 토크를 결정하는 것에는 차중의 값은 불요하다.
