To provide a four-wheel drive vehicle which can properly switch a stationary traveling mode and a normal traveling mode.SOLUTION: A four-wheel drive vehicle 1 having left and right front wheels 191, 192 as main drive wheels, and left and right rear wheels 193, 194 as auxiliary drive wheels is transited to a normal traveling mode from a stationary traveling mode when a first transition condition is satisfied, and transited to the stationary traveling mode from the normal traveling mode when a second transition condition is satisfied. In the stationary traveling mode, a drive force transmitted to the left and right rear wheels 193, 194 is reduced more than that in the normal traveling mode, and at least either of the first transition condition and the second transition condition is changed according to weather information acquired by communication with the outside of the vehicle such as road inter-vehicle communication.SELECTED DRAWING: Figure 4

    【課題】定常走行モードと通常走行モードとの切り替えを適切に行うことが可能な4輪駆動車を提供する。【解決手段】主駆動輪としての左右前輪191,192及び副駆動輪としての左右後輪193,194を備えた4輪駆動車1は、第1遷移条件を満たすときに定常走行モードから通常走行モードに移行し、第2遷移条件を満たすときに通常走行モードから定常走行モードに移行する。定常走行モードでは、通常走行モードよりも左右後輪193,194に伝達される駆動力を低減すると共に、路車間通信等の車両外部との通信によって得られた気象情報に応じて第1遷移条件及び第2遷移条件の少なくとも何れかを変更する。【選択図】図4
