摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device for an automatic transmission for a vehicle capable of favorably restricting undershooting of engine rotation speed or speed change shock caused by that even when engine output torque fluctuation factors are generated in power-off upshifting. SOLUTION: When it is determined that prescribed control for upshifting is started as an accelerator pedal 50 is not operated by a power-off upshifting control start determining means 102, in a case where it is determined that such factors as to fluctuate input torque T IN in the automatic transmission 14 are generated by an input torque fluctuation factor generation determining means 104, engagement pressure of a prescribed hydraulic friction engagement device is corrected by correction quantity in accordance with the factors to fluctuate the input torque T IN by a hydraulic pressure correction control means 114. Even when the output torque fluctuating factors for the engine 10 are generated, undershooting of the engine rotation speed N E or speed change shock caused by that is thus favorably restricted.

摘要： PROBLEM TO BE SOLVED: To further reduce an energy loss of an oil pump by controlling a supply amount of lubricating oil to a minimum as required according to an operating state of a belt type continuously variable transmission. SOLUTION: The energy loss of the transmission efficiency η of the belt type continuously variable transmission is regarded as heat energy converted by heating caused by friction of a transmission belt or the like, and the supply amount QOIL of operating oil for lubricating a belt is controlled based on the transmission efficiency η which varies according to the operating state of the belt type continuously variable transmission. By this, lubrication of the belt can be always equally and properly controlled to a different heating amount according to the operating state, and the energy loss of the oil pump caused by excessive supply of the lubricating oil is reduced, as a result, the fuel consumption is improved.

摘要： PROBLEM TO BE SOLVED: To provide a double-pinion-type planetary gear having sufficient durability. SOLUTION: Respective positions of a pair of oil blowing holes 112, 114 provided for pinion pins 84, 86 for journaling a pair of pinions 34, 36 of a planetary gear are set so that delivery flows of lubricating oils delivered from the holes are substantially same, based on centrifugal oil pressure occurring following rotation of a carrier 28. Even if radial positions of a pair of pinions 84, 86 are different from each other, difference between the centrifugal oil pressure caused by the difference of the positions, thus difference between lubricating oil amounts delivered from the oil blowing holes 112, 114 are modulated. Therefore, lubricating oil amounts delivered toward respective pair of pinions 34, 36 are substantially same, so that durability of this double-pinion-type planetary gear is improved.
