摘要： In a hydraulic control system for an automatic transmission, a valve element of an accumulator closes communication between a pressure switch circuit and a detection circuit when a hydraulic pressure applied to the detection circuit is lower than a predetermined hydraulic pressure, and opens communication between the pressure switch circuit and the detection circuit when the applied pressure is higher than or equal to the predetermined hydraulic pressure. A switching element opens communication between one end of the pressure switch circuit and an exhaust circuit when the other end of the pressure switch circuit does not communicate with the detection circuit, and closes communication between the one end and the exhaust circuit when the other end communicates with the detection circuit.

摘要： A hydraulic control apparatus is improved in reliability during a garage shifting with reducing costs of the apparatus. An electronic control unit controls equalizing the shift pattern (on-off pattern) during a first garage shifting when a manual valve is shifted from the neutral position to a drive position to the shift pattern during a second garage shifting when the manual valve is shifted from the neutral position to the reverse position. A control valve unit controls the hydraulic pressure applied to a first engagement element during the first garage shifting while controlling the hydraulic pressure applied to a second engagement element during the second garage shifting.

摘要： Under the learning mode during a vehicle stationary condition, an oil pressure of the friction engagement element for setting a standby oil pressure value is increased by a predetermined step pressure while a transmission input shaft rotational speed has been maintained, and a standby oil pressure is set for shifting the friction engagement element to an engagement side. A controlled value is verified whether it is within a predetermined range corresponding to the predetermined step pressure when a change of the input value due to decrease of the turbine rotational speed satisfies a predetermined condition. The controlled value is learned when the controlled value is within the predetermined range corresponding to the step pressure. A step pressure larger than the step pressure is set when the controlled value is beyond the predetermined range corresponding to the step pressure.
