To provide a control device for a four-wheel drive vehicle which can stably control operation of a transmission and a hydraulic clutch in start of a driving power source.SOLUTION: A control device 100 has a travel state grasp part 102 for grasping a travel state of a vehicle 10, and a first clutch control part 104 for controlling the magnitude of an engaging degree of a first clutch transmitted through a clutch 46 for front wheel driving. The control device 100 performs control in start for prioritizing supply of oil to a transmission 20 over supply of oil to a clutch 46 for front wheel driving composed of a hydraulic clutch, until it satisfies such a condition that an oil discharge amount V in an oil pump 150 reaches a predetermined reference amount VS, under such a condition that a driving power source 12 starts output.SELECTED DRAWING: Figure 1
【課題】駆動力源の始動時において変速装置や油圧式クラッチの動作を安定的に制御可能な四輪駆動車両用制御装置の提供を目的とした。【解決手段】制御装置100は、車両10の走行状状態を把握するための走行状態把握部102と、前輪駆動用クラッチ46を介して伝達される第一クラッチの係合度の大きさを制御する第一クラッチ制御部104とを有する。制御装置100は、駆動力源12が出力を開始することを条件として、オイルポンプ150におけるオイル吐出量Vが所定の基準量Vsに達する条件を満足するまで、変速装置20に対するオイルの供給を、油圧式クラッチからなる前輪駆動用クラッチ46に対するオイルの供給よりも優先させる始動時制御を行う。【選択図】図1
