Abstract
An automatic centrifugal clutch is interposed in a power transmission system between an engine and a driving wheel. A motor, which is capable of generating electricity, is supplied with electricity from a battery to generate auxiliary power. The motor is connected to a crankshaft of the engine. An acceleration data acquisition component acquires the accelerator operation amount and the accelerator operation speed. A delay time setting component sets a delay time according to the acceleration data. A motor controller supplies the motor 13 with a magnitude of electricity in accordance with the acceleration operation amount after the delay time has elapsed from the moment when an accelerator grip was moved from an idle position.
Claims22
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 and an accelerator operation speed of the accelerator operating element;
- a delay time setting component arranged to set a delay time by which start of operation of the motor is delayed based upon the accelerator operation amount of the accelerator operating element and the accelerator operation speed of the accelerator operating element;
- and
- a motor controller arranged to supply the motor with a magnitude of electricity in accordance with the acceleration data after the delay time has elapsed from a moment when the accelerator operating element was moved from an idling position.
