PROBLEM TO BE SOLVED: To provide a hydraulic control device of an automatic transmission mounted in an idling stop vehicle, capable of preventing starting errors against driver's intention while reducing time taken from engine restart to vehicle restart without the need to provide an electric pump.SOLUTION: Brake release determination means determines whether it is certain that a brake is released although a brake signal is turned on; and if it is determined that it is certain that the brake is released, then the number of revolutions of an engine is set small by a motor before restarting the engine, and the number of revolutions of the engine is controlled so that a driving force does not surpass a braking force while filling a working fluid in a clutch pressure circuit.

    【課題】電動ポンプを備えることなく、エンジン再始動から車両の再発進までの時間を短縮しつつ、運転者の意図しない誤発進を防止することのできる、アイドルストップ車両に搭載される自動変速機の油圧制御装置の提供を目的とした。【解決手段】ブレーキリリース判定手段により、ブレーキ信号はONであってもブレーキの解放が確実な状態を判定し、ブレーキの解放が確実な状態と判定した場合は、エンジンの再始動前にエンジンをモータにより低速回転させ、クラッチ圧回路に作動油を充填しつつ、駆動力がブレーキ制動力を上回らないようにエンジン回転速度を制御する。【選択図】図1
