    摘要: In a condition of a vehicle which remains stationary or is about to stop and of a forward second speed having a clutch and a brake engaged, an N range is changed from a D range based on a shift lever operation and a forward range pressure is discharged from a manual shift valve. At this time, an orifice and a check ball are used to delay discharge of oil paths which communicate with a linear solenoid valve relative to discharge of an oil path a1 which communicates with a linear solenoid valve. Specifically, release of the brake is delayed relative to release of the clutch, so that a shift by way of a forward first speed through engagement of a one-way clutch can be prevented.

    摘要: An exemplary control device includes an input torque detection unit that detects an input torque input to the input shaft; and a controller that: determines torque distribution of two of the friction engagement elements that form the shift speeds; and calculates a transmission torque of the two friction engagement elements based on the input torque and the torque distribution and sets the engagement pressure to obtain a torque capacity that can transmit the transmission torque, wherein the controller sets the engagement pressure such that slippage does not occur in the two friction engagement elements in a state where engagement of the two friction engagement elements forms the shift speeds and such that, even if an additional friction engagement element engages based on the line pressure while the two friction engagement elements are engaged, one of the three friction engagement elements is caused to slip.

    摘要: An automatic transmission including an input shaft connected to a drive source; an output shaft connected to a driving wheel; a one-way clutch; friction engagement elements which establish speeds by changing a transmission path between the input shaft and the output shaft based on the application state of the friction engagement elements and application of the one-way clutch, one of the friction engagement elements being a brake that is applied when coasting in a take-off speed. The automatic transmission also includes a controller that determines whether it is possible to initially establish the take-off speed using the one-way clutch based on a predetermined condition, and, if not possible, then the controller establishes the take-off speed by applying the brake.
