摘要： The fail-safe gear step switching valve (120) can be switched to the first position to establish the low-speed side fail-safe gear step (third speed-change gear step) or the second position to establish the high-speed side fail-safe gear step (fifth speed-change gear step). Upon the failure state of the solenoid valve device (SLC1, SLC2), the fail-safe gear step switching valve is held at the second position by the line hydraulic pressure (PL1). Two kinds of the fail-safe gear steps i.e., the third speed-change gear step and the fifth speed-change gear step can be established depending on the vehicle state just before the failure occurrence of the fail-safe gear step switching valve. Even if the D→N operation of the shift lever (72) is performed during the vehicle running in the fifth speed-change gear step, the fail-safe gear step switching valve remains at the second position to establish the fifth speed-change gear step even upon the shifting operation of the shift lever to the “D” position again.

摘要： In a hydraulic control device, when a solenoid pressure from a linear solenoid valve is not supplied to a brake, which is normally not engaged at the same time as a brake, not to engage the brake, a switching valve is supplied with a line pressure as a signal pressure for establishing a blocked/discharge state in which supply of the solenoid pressure to the brake is blocked and a hydraulic pressure can be discharged from the brake. When the solenoid pressure is supplied to the brake to engage the brake, the switching valve is supplied with a modulator pressure, which is lower than the line pressure, as a signal pressure for establishing a communicated state in which the solenoid pressure can be supplied to the brake.

摘要： A hydraulic control apparatus of an automatic transmission which can supply a hydraulic oil pressure to one or more hydraulic servos of frictional engagement elements at a failure time when a de-energized condition is attained. The apparatus includes a normally closed type first solenoid valve for generating the hydraulic oil pressure, and a normally open type second solenoid valve for outputting a first signal pressure for adjusting and controlling an oil pressure to a line pressure; a signal output device for outputting the line pressure or a modulator pressure. The line pressure is reduced to a certain pressure, as a second signal pressure at a normal time, and causes the second signal pressure not to be output at the failure time; and an oil pressure switching device switchable between a normal time position in which the hydraulic oil pressure from the first solenoid valve can be supplied to the hydraulic servo, and a failure time position in which the input line pressure is supplied to the hydraulic servo, is switched to the normal time position by the first signal pressure and second signal pressure, which are input opposed to each other, being input, and switched to the failure time position by the first signal pressure being input and the second signal pressure not being input.
