摘要： An automatic transmission control device controls multiple speed changes in which shifting from first speed to second speed occurs during shifting from second speed to first speed. The control device includes a shift lever position sensor, an ECT_ECU, and an AT linear solenoid. The ECT_ECU includes a circuit that detects multiple speed changes; a circuit that controls the AT linear solenoid such that an engagement pressure of an engaged first speed engine brake friction element sweeps down when multiple speed changes are detected; and a circuit that commands a shift to second speed once a predetermined time has passed since the detection of multiple speed changes assuming that the engagement pressure of the first speed engine brake friction element has sufficiently swept down.

摘要： The clutch oil pressure (PC1) supplied to a hydraulic controller of an automatic transmission is detected. If it is detected that the clutch oil pressure (PC1) is less than or equal to a first threshold value PA when a first oil pump cooperative with a drive power source is to stop, the second oil pump is driven. Therefore, after the oil pressure (for example, PY) remaining from the first oil pump has decreased, the second oil pump is driven, and an oil pressure (PX) needed for the hydraulic control of friction engagement elements is maintained. If it is detected that the clutch oil pressure (PC1) is greater than or equal to a second threshold value (PB) when the first oil pump is to be driven, the second oil pump is stopped. Therefore, the second oil pump is stopped when the oil pressure provided by the first oil pump rises to such a level that the oil pressure (PX) can be secured. Thus, the load on the second oil pump is reduced so as to allow it to be reduced in size.

摘要： A planetary gear transmission is provided having a sun gear, ring gear and planet carrier mounted in a housing. A plurality of compound planet gears are rotatably mounted to the planet carrier. The planet carrier is connected to one of either an input shaft or an output shaft while the ring gear is connected to the other of either the input shaft or output shaft. A clutch engageably and disengageably couples the sun gear for rotation with one of the input or output shafts to which the planet carrier is coupled. A brake engageably and disengageably fixes the sun gear against rotation relative to the housing. A hydraulically engaged/spring disengaged non-rotating piston is mounted in the housing and is slidable in response to fluid pressure between an engaged position for engaging one of the clutch and the brake and a retracted position for disengaging the one of the clutch and the brake. Whereby the transmission operates in a first range when the clutch is engaged and the brake is disengaged and operates in a second range when the brake is engaged and the clutch is disengaged.

摘要： An automatic transmission achieves a desired shift through an initial stage shift in which a first engagement element is released and a third engagement element is engaged, and a final stage shift in which a second engagement element is released and a fourth engagement element is engaged. A control apparatus sets an estimated rotation acceleration for a transmission input shaft in accordance with an input torque and an input torque rotation acceleration speed, and controls the release of the second engagement element for moving to the final stage shift according to the estimated rotation acceleration. As a result, it is possible to prevent a shifting delay and/or degradation that occurs between the initial stage and the latter stage by continuous transmission of the input rotation (engine rotation) change when moving from the initial stage to the later stage.

摘要： An electro-hydraulic control for a continuously variable transmission includes a first regulator valve which is controlled to provide a high pressure output to control the ratio within the continuously variable transmission and a second regulator valve which is controlled to provide an engagement pressure for torque transmitting mechanisms within the transmission. The control incorporates multiplexing of the valve components, creates prioritization of fluid flow, detection of priority mode of operation, over-pressurization protection valves, and ensures a minimum of fluid flow to the torque transmitting mechanisms and the oil cooler.
