  • Patent number: 12103405
    Abstract: A power distribution apparatus for an electric vehicle includes a power distribution mechanism configured to distribute power output from an electric motor to front and rear wheels, and a controller configured to control the power distribution mechanism. The power distribution mechanism includes a first clutch configured to fix a power distribution ratio during straight traveling to a first distribution ratio at which first power distributed to the rear wheels and second power distributed to the front wheels are nearly same, and a second clutch configured to fix the power distribution ratio during straight traveling to a second distribution ratio at which the first power is larger than the second power. The controller is configured set the second clutch to an engaged state and sets the first clutch to a half-engaged state during regenerative braking.
