PROBLEM TO BE SOLVED: To make motive energy recoverable in use of an electric motor in time of decelerating a vehicle, and simultaneously obviate the worsening of durability due to overspeediness in the motor in this starting assist device which is so designed as to drive a driven wheel by the motor in time of starting the vehicle, assisting its starting, and stop the drive of the motor after the starting. SOLUTION: An electric motor 6 and both driven wheels 4L and 4R are always connected together via a transmission 8, and in time of decelerating a vehicle, this motor 6 is made to function as a generator, thereby charging electric power from the motor 6 to a battery 11. With the increase of speed, a reduction gear ratio in the transmission 8 is reduced, controlling a rise in rotational speed of the motor 6 due to reverse drive from each side of these driven wheels 4L and 4R. |
