摘要： A hydraulic control device for a multi-speed automatic transmission includes friction engagement elements, several hydraulic servos that engage and release the friction engagement elements, solenoid valves for engagement control, and a sorting switch valve that allocates engagement pressure from at least one of the solenoid valves for engagement control to two of the hydraulic servos. The sorting switch is switched between a first position that supplies engagement pressure to one of the two hydraulic servos in at least a Reverse, non-drive range and a specific Forward gear range, and a second position that supplies engagement pressure to the two hydraulic servos in other than the Forward range. The hydraulic control device supplies the engagement pressure to the two hydraulic servos when an all-solenoids-off failure occurs and the sorting switch is in the second position, and cuts off a source pressure to all solenoid valves when an all-solenoids-off failure occurs while the sorting switch valve is in the first position.

摘要： The present invention provides a control apparatus for an automatic transmission which is capable of preventing friction engagement elements from being kept in an engagement state in accordance with the traveling state of a vehicle when a shift lever is operated to the position where an neutral range is formed, even if the malfunction of one or more solenoid valves occurs.In the case where the shift range is switched to an N range (“YES” in the step S11), an ECU controls an So3 solenoid valve to enter an energized state (step S15), and controls a speed change mechanism to enter a non-transmission state, when the ECU judges that vehicle speed V is smaller than an N range forming method changing threshold Vn (“YES” in step S13). On the other hand, the ECU controls an SL1 linear solenoid valve to enter a de-energized state (step S17), and controls the speed change mechanism to enter the non-transmission state, when the ECU judges that the vehicle speed V is no less than the N range forming method changing threshold Vn (“NO” in step S13).
