The control apparatus includes a storage unit for storing an assisted state and a regenerated state in a single event of use of the motor-assisted bicycle by a user, and a control quantity corrector for correcting a control quantity of the assistive control process and a control quantity of the regenerative control process based on the assisted state and the regenerated state which are stored in the storage unit. | 04-05-2012 |
20120187881 | CONTROL DEVICE FOR ELECTRIC VEHICLE - In an electric vehicle, a throttle spring restores a throttle opening on the side of a minimum opening when the accelerator is not operated. A driving section drives a motor according to the throttle opening. The throttle spring pushes an accelerator grip to a creep speed reference opening so as to reduce the throttle opening. A creep speed control section supplies a motor driving instruction to the driving section so that the electric vehicle is advanced at minute vehicle speed. The electric vehicle can also be backed at predetermined minute vehicle speed when the throttle opening is smaller than the creep speed reference opening. | 07-26-2012 |
