DRIVE CONTROL METHOD FOR MOTOR-DRIVEN TWO-WHEELED VEHICLE, AND MOTOR-DRIVEN THREE-WHEELED BICYCLE AND MOTOR-DRIVEN FOUR WHEELED WAGON USING THIS DRIVE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To make driving operation easier and smooth re-acceleration possible from deceleration such as turning by using a pulse current applied to an electric motor by controlling in such a manner that the time of current applied per unit time of this pulse current becomes shorter compared to that in an ordinary drive time by interlocking with the braking operation of a brake lever. SOLUTION: Drive of an electric motor 2 is performed by a pulse current and, by interlocking with the brake operation, the time of applying current per unit time of the pulse current is made shorter compared to the ordinary running and driving in its control method. Then, the output of the electric motor 2 is reduced, drive wheels 4a, 4b are set to a free state through one-way clutches 6a, 6b, and turning operation can be carried out smoothly. In this way, the response during the rise time of the electric motor can be made better during re-acceleration by the switch operation, and thus smooth shifting can be performed from the state of speed drop during turning to the state of acceleration, so that the driving operation can be made easier and safe running can be realized.
