Patent ID: 8424626

Claim:
A vehicle, in which a vehicle body frame is provided with a crankshaft, a primary gear integrated with the crankshaft, a primary driven gear engaged with the primary gear, a clutch mechanism coupled with the primary driven gear that connects/disconnects power of an engine, and a transmission provided on the output side of the clutch mechanism, and to which the engine that transmits the power to a drive shaft via the transmission is attached comprising: a one-way clutch for transmits the power from the crankshaft to the primary gear and for not transmitting the power from the primary gear to the crankshaft, said one-way clutch being provided between the crankshaft and the primary gear; a regenerative brake motor for enabling braking of a wheel and enabling conversion of torque of the wheel to electric energy, said regenerative brake motor being provided between the primary gear and a drive shaft of the wheel; and a controller for causing the regenerative brake motor to generate electric energy when a revolution speed of the primary gear is high in a revolution ratio between the crankshaft and the primary gear, while causing the regenerative brake motor to run idle when a revolution speed of the crankshaft is equal to or higher than the revolution ratio of the revolution speed of the primary gear.
