To provide a four wheel drive vehicle which is capable of restraining NV when functioning a clutch disposed between an electric motor used as a driving source of a vehicle and left and right wheels as fastening state and furthermore to provide a driving device which is capable of restraining NV when functioning the clutch of the driving device which is provided with the electric motor and the clutch as the fastening state.SOLUTION: A control device 4 of a four wheel drive vehicle 1 functions a clutch mechanism as driving force transmissible state by controlling rotational speed of a front motor 31 and then rotating and synchronizing an input rotary member and an output rotary member of other clutch mechanism among the first and second clutch mechanism 34, 35 after functioning the clutch mechanism as the driving force transmissible state by controlling the rotational speed of the front motor 31 used as an auxiliary drive source and then rotating and synchronizing the input rotary member and the output rotary member of one of the clutch mechanism among the first and second clutch mechanism 34, 35 when performing switch from two wheel drive state to four wheel drive state.SELECTED DRAWING: Figure 1
【課題】車両の駆動源である電動モータと左右の車輪の間に配置されたクラッチを締結状態にする際のNVを抑制することが可能な4輪駆動車を提供することを目的とする。また、本発明は、電動モータとクラッチとを備えた駆動装置のクラッチを締結状態にする際のNVを抑制することが可能な駆動装置を提供する。【解決手段】4輪駆動車1の制御装置4は、2輪駆動状態から4輪駆動状態への切り替えを行うとき、副駆動源であるフロントモータ31の回転速度を制御して第1及び第2のクラッチ機構34,35のうち一方のクラッチ機構の入力回転部材と出力回転部材とを回転同期させて当該クラッチ機構を駆動力伝達可能な状態とした後、フロントモータ31の回転速度を制御して第1及び第2のクラッチ機構34,35のうち他方のクラッチ機構の入力回転部材と出力回転部材とを回転同期させて当該クラッチ機構を駆動力伝達可能な状態とする。【選択図】図1
