PROBLEM TO BE SOLVED: To provide a hydraulic control device of a driving device for a vehicle capable of suppressing fuel consumption by suppressing wasteful supply of oil, and sufficiently supplying oil to a plurality of object portions to be lubricated and cooled without increasing a rotating speed of an internal combustion engine by effectively activating an electric oil pump.SOLUTION: A hydraulic control device of a driving device for a vehicle includes a first solenoid valve SL1 capable of supplying a control pressure PSL1 while adjusting the same, a pressure adjustment/block switching portion 61 capable of switching a pressure adjustment state for adjusting a secondary pressure Psec on the basis of the control pressure PSL1 and supplying the same to a second brake B2, and a block state for blocking the secondary pressure Psec by the control pressure PSL1, and a supply/block switching portion 62 capable of switching a supply state for supplying electric oil pump pressure PEO/P to the second brake B2 and a block state for blocking the electric oil pump pressure PEO/P by the control pressure PSL1. 【課題】オイルの無駄な供給を抑制して燃費の低下を抑えると共に、電動オイルポンプを有効に活用し、内燃エンジンの回転速度を上げずに複数の潤滑や冷却がなされる対象部へ十分な油を供給できる車両用駆動装置の油圧制御装置を提供する。【解決手段】制御圧ＰＳＬ１を調圧して供給可能な第１のソレノイドバルブＳＬ１と、セカンダリ圧Ｐｓｅｃを制御圧ＰＳＬ１に基づいて調圧して第２のブレーキＢ２に供給する調圧状態とセカンダリ圧Ｐｓｅｃを遮断する遮断状態とに、制御圧ＰＳＬ１により切換可能な調圧遮断切換え部６１と、電動オイルポンプ圧ＰＥＯ／Ｐを第２のブレーキＢ２に供給する供給状態と電動オイルポンプ圧ＰＥＯ／Ｐを遮断する遮断状態とに制御圧ＰＳＬ１により切換可能な供給遮断切換え部６２と、を備える。【選択図】図３
