  • Patent number: 11548384
    Abstract: When evacuation travel is performed using only a drive power from one drive power source of an engine and a rotary machine, a drive power distribution device is prohibited from switching to a four-wheel-drive state and thus evacuation travel is performed in a two-wheel-drive state in which a loss in a power transmission device is relatively small. Accordingly, in a four-wheel-drive vehicle, it is possible to increase an evacuation-travelable distance when evacuation travel is performed using only the drive power from one drive power source of the engine and the rotary machine.
