Abstract: An electric motorcycle includes a vehicle controller that outputs an instruction value based on an operation amount of at least an accelerator grip, and a motor driving unit that supplies a driving electric power in accordance with the instruction value to an electric motor. The vehicle controller is disposed outside a case that includes the motor driving unit disposed therein. The distance from the steering handle to the vehicle controller is shorter than the distance from the steering handle to the motor driving unit in a side view of the vehicle body, to simplify the cost of the electric wire and the work required to lay out the electric wire.

Abstract: An electric two-wheel vehicle includes a battery case that accommodates two batteries. The battery case is open in an upward direction. A head pipe supports a steering shaft and is connected to a front portion of the battery case. The battery case includes a beam portion that is disposed between the two batteries and extends rearward from a front wall portion of the battery case. Accordingly, it is possible to easily attach and detach the batteries with respect to a vehicle body for charging, protect the batteries, and secure the rigidity of a vehicle body frame.

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 rotational speed detection component detects the speed of the crankshaft. A rotational speed estimation component is adapted to estimate the engagement completion rotational speed, which is a rotational speed at which the automatic centrifugal clutch is completely engaged, based upon the acceleration data acquired by the acceleration data acquisition component.

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.

Abstract: A relative position detection device is designed with multiple Hall Effect sensors. In one embodiment, the multiple Hall Effect sensors comprise two different types of Hall Effect sensors. The two different types can be linear and digital. The output of the sensors is used to determine the position an accelerator control, such as a twist grip, and to control an engine or motor in accordance with the operator demand evidenced by the position of the accelerator control.
