    摘要: A hydraulic control apparatus of an automatic transmission. The hydraulic control apparatus of the automatic transmission has a hydraulic servo for controlling an engaging state of a clutch C-1 on the basis of supplied oil pressure, a linear solenoid valve for C-1 for outputting signal pressure by adjusting the oil pressure, a control valve for outputting control pressure provided by adjusting line pressure PL on the basis of the signal pressure of the linear solenoid valve for C-1, and a C-1 apply relay valve for inputting, selectively switching and outputting the control pressure and the line pressure PL to the hydraulic servo. An orifice for regulating the flow rate of the oil is arranged in an oil path g for inputting the line pressure PL to this C-1 apply relay valve.

    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 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.
