To control regenerative charge based on a vehicle occupant's intention.
In an object, in which the acceleration is operated by a handle grip 5A, the direction of operation of a handle grip 5A is divided into the side of acceleration and the side of regeneration, with a free point, where the accelerator grip 5A returns naturally by spring force, as a boundary. The accelerator grip 5A needs larger operation torque on the side of operating it to the deceleration side than to the acceleration side. A map for deciding a regenerative current, base on car speed and accelerator aperture, is provided. The regenerative current is enlarged more the larger the accelerator aperture becomes and besides the larger the car speed becomes. It is controlled to enlarge generated regenerative energy the larger the accelerator grip 5A is turned to the regeneration side.
