  • Patent number: 8970356
    Abstract: A vehicle approach notification apparatus for an electric motorcycle, which outputs notification sound for notifying a walker or the like of approach of a vehicle from a speaker attached to a vehicle body includes a control unit for controlling the notification sound. The control unit is attached to a position, displaced rather forwardly of the vehicle body, of a bottom face in an accommodating box disposed below a seat of the electric motorcycle. A cover plate, which configures part of the bottom of the accommodating box, is removably disposed above the control unit. A low voltage battery as a power supply for auxiliaries is accommodated on the bottom of the accommodating box displaced rather rearwardly of the vehicle body from the control unit. The cover plate is disposed so as to cover an upper portion of the low voltage battery in flush with an upper face of the control unit.

  • Patent number: 8547218
    Abstract: To provide a vehicle approach notification control apparatus for an electric motorcycle, which can output notification sound for notifying a walker or the like of approach of an electric motorcycle with an appropriate sound volume. The vehicle approach notification control apparatus for an electric motorcycle includes a speaker for generating notification sound equivalent to engine sound of an engine driven motorcycle of a vehicle category that is the same as a vehicle category of the electric motorcycle in response to a motor speed of an electric motor or a vehicle speed. The vehicle approach notification control apparatus includes a pseudo engine sound volume storage device configured to store sound volume data of engine sound with respect to the entire running sound upon running of the engine driven vehicle, and a control unit for controlling the notification sound.
