His innovative designs focus on enhancing the functionality and efficiency of electric motorcycles and electrically assisted vehicles.

Latest Patents

One of Obayashi's latest patents is for a straddle-type electric vehicle. This electric motorcycle features a vehicle controller that outputs an instruction value based on the operation amount of at least an accelerator grip. The motor driving unit supplies driving electric power in accordance with this instruction value to an electric motor. Notably, the vehicle controller is positioned outside a case that houses the motor driving unit, which simplifies the cost and layout of the electric wiring. The design ensures that the distance from the steering handle to the vehicle controller is shorter than the distance to the motor driving unit, optimizing the overall structure.

Another significant patent is for an electrically assisted vehicle. This vehicle includes a body, pedals for human power input, and a crank that is coupled to the pedals. The crank is freely rotatably supported on the vehicle body, and at least one wheel is attached to the body, rotating in response to the crank's movement. The vehicle is equipped with two electric motors that drive the wheel, along with a torque detection unit that measures the torque applied to the crank. The torque command value calculation unit processes this data to drive the electric motors efficiently, ensuring a seamless riding experience.
