  • Operating noise control device and operating noise control method for vehicle
    Patent number: 8594870
    Abstract: A vehicle (1, 17) includes an electric drive motor (5, 19), an inverter (4) that provides a drive current to the electric motor (5, 19) and a controller (13) that controls the inverter (4). The controller (13) functions as a beat noise generation system that creates beat noise by generating a second operating noise containing a component an order of which is very close to a value representing an order of an operating noise generated in proportion to a rotation speed of the electric motor (5, 19) so as to create desirable traveling noise corresponding to an accelerating state while the vehicle accelerates.
