Patent ID: 7784574

Claim:
A hybrid motorcycle comprising: at least one wheel; a power transmission system connected to the at least one wheel; a power unit including an engine and a motor connected to a crankshaft of the engine, the motor being configured to apply auxiliary power to the crankshaft and to generate electricity when driven by the crankshaft; an accelerator operating element connected to the power unit; an automatic centrifugal clutch interposed in the power transmission system between the power unit and the at least one wheel; an acceleration data acquisition component arranged to acquire as acceleration data at least an accelerator operation amount of the accelerator operating element; a rotational speed detection component arranged to detect a rotational speed of at least one of the crankshaft and a component that rotates synchronously with the crankshaft; a rotational speed estimation component arranged to estimate an engagement completion rotational speed, which is a rotational speed at which the automatic centrifugal clutch is completely engaged, based upon the acceleration data; and a motor controller programmed and arranged to supply the motor with a magnitude of electricity in accordance with the acceleration data when the rotational speed detected by the rotational speed detection component has reached the estimated engagement completion rotational speed.
