VEHICLE HYDRAULIC CONTROL DEVICE

To provide a vehicle hydraulic control device capable of avoiding increasing in number of component parts or increasing in weight and cost by eliminating an exclusive accumulator and capable of assuring a recovering responsiveness got from an idling stop state even if an exclusive inspection step is eliminated.SOLUTION: There are provided a mechanical oil pump (2) rotated by a driving force of an engine; a pressure adjustment valve (10) for adjusting pressure of oil discharged from the oil pump (2); an on-off valve (20) arranged at an oil passage (L1) between the oil pump (2) and the pressure adjustment valve (10), having a configuration that is opened at a pressure more than a predetermined threshold oil pressure (P1); and a branched oil passage (L12) branched from between the oil pump (2) and the on-off valve (20) and communicated with a starting engagement element (41) to cause it to be engaged at the time of starting of a vehicle. The threshold oil pressure (P1) is set to a pressure higher than a pressure in the oil passage (L1) generated by rotation of the oil pump (2) at the starting time of the engine.SELECTED DRAWING: Figure 2 【課題】専用のアキュームレータを省略することで部品点数の増加や重量・コストの増加を回避でき、かつ専用検査工程を不要としながらも、アイドリングストップ状態からの復帰応答性を確保することができる車両の油圧制御装置を提供する。【解決手段】エンジンの駆動力で回転する機械式のオイルポンプ（２）と、オイルポンプ（２）から吐出されたオイルを調圧するための調圧バルブ（１０）と、オイルポンプ（２）と調圧バルブ（１０）との間の油路（Ｌ１）に設けた所定の閾値油圧（Ｐ１）以上で開く構成の開閉弁（２０）と、油路（Ｌ１）におけるオイルポンプ（２）と開閉弁（２０）との間から分岐して車両の発進時に係合させる発進係合要素（４１）に連通する分岐油路（Ｌ１２）と、を備え、閾値油圧（Ｐ１）は、エンジンの始動時のオイルポンプ（２）の回転による油路（Ｌ１）の圧力よりも高い圧力に設定されている。【選択図】図２
