The invention relates to a four-wheel-drive vehicle. 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 the 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.
本发明涉及四轮驱动车辆。在仅使用来自发动机和旋转机中的一方的驱动力源的驱动力来进行退避行驶时,禁止将分动器设为四轮驱动状态,因此在动力传递装置的损失比较小的二轮驱动状态下进行退避行驶。由此,在四轮驱动车辆中,在仅使用来自发动机和旋转机中的一方的驱动力源的驱动力来进行退避行驶时,能延长可退避行驶的距离。
