ストンと、該サーボピストンの締結側に作動油圧
を供給する締結側回路と、サーボピストンの解放
側に作動油圧を供給する解放側回路と、を備えた
自動変速機の油圧制御装置において、前記サーボ
ピストンが所定の摩擦要素を解放するとき、解放
側回路からサーボピストンに供給される解放側作
動油圧の高まりに応じてサーボピストンの締結側
作動油圧を可変制御する可変制御手段を設けたこ
とを特徴とする自動変速機の油圧制御装置。 An automatic device comprising: a servo piston that engages and releases a predetermined friction element; an engagement side circuit that supplies hydraulic pressure to the engagement side of the servo piston; and a release side circuit that supplies hydraulic pressure to the disengagement side of the servo piston. In a hydraulic control device for a transmission, when the servo piston releases a predetermined friction element, the engaging side working oil pressure of the servo piston is variably controlled according to the increase in the releasing side working oil pressure supplied to the servo piston from the releasing side circuit. 1. A hydraulic control device for an automatic transmission, characterized in that a variable control means is provided to control the transmission.
