To make a motor truck easily start on an uphill road by a simple technique with the motor-driven motor truck as an object.SOLUTION: When a rotation number is zero when a pedal-in amount of an accelerator pedal is 0%, torque Ta is generated. When a retreat occurs at a start on an uphill road, the rotation number is decreased. When the rotation number is decreased, the torque is increased. Therefore, a retreat force and a propulsion force are balanced in due time. As a result, the retreat is converged into a constant velocity motion in due time. In order to decide the torque as above, a value of vehicle weight is unnecessary.SELECTED DRAWING: Figure 4

    【課題】モータ駆動の貨物自動車を対象に、簡易な手法で坂道発進をしやすくすること。【解決手段】アクセルペダルの踏み込み量が0%の場合、回転数がゼロであるとき、トルクTaが発生する。坂道発進において後退が発生した場合、回転数が減少する。回転数が減少すると、トルクは増大する。このため、やがて後退力と推進力とが釣り合う。この結果、後退は、やがて等速運動に収束する。このようにトルクを決定するには、車重の値は不要である。【選択図】図4
