    摘要: A hydraulic control system for a dual clutch transmission includes a plurality of solenoids and valves in fluid communication with a plurality of clutch actuators and with a plurality of synchronizer actuators. The clutch actuators are operable to actuate a plurality of torque transmitting devices and the synchronizer actuators are operable to actuate a plurality of synchronizer assemblies. Selective activation of combinations of the solenoids allows for a pressurized fluid to activate at least one of the clutch actuators and synchronizer actuators in order to shift the transmission into a desired gear ratio.

    摘要: A method of regulating operation of an automatic transmission includes identifying a tie-up condition of the automatic transmission, adjusting a pressure of a transmission element in response to the tie-up condition and determining whether a first gear ratio of the automatic transmission holds. The pressure is set to zero if the gear ratio does not hold and a faulty transmission element is identified as one associated with a second gear ratio that is lower than said first gear ratio.

    摘要: A control apparatus of an automatic transmission includes first, second and third frictional elements, first and second shift control sections issuing a hydraulic pressure command to the first, second and third frictional elements for appointment and release thereof at primary and secondary shifts, a judging section judging a shift from a first speed stage to a third speed stage, and a third shift control section initiating the primary shift when the shift is judged, and initiating the secondary shift before an end of the primary shift while executing the primary shift when a gear ratio reaches a first predetermined gear ratio. the third shift control section compares two pressure command values of the first frictional element, respectively issued by the first and second shift control sections for the primary and secondary shifts, and selects a greater pressure command value, and outputs it to the first frictional element.

    摘要: An engine starting system for a power train including an engine and an automatic transmission includes an engine stop/restart controller. The automatic transmission having special mode includes first and second planetary gear sets having respective sun gears, a turbine shaft, an output gear, a forward clutch and a 2-4 brake. The forward clutch sets the automatic transmission in a drive condition when engaged and in a neutral condition when disengaged. If the special mode is selected under conditions where the output gear is locked, the sun gear of the first planetary gear set is locked. During execution of automatic engine stop control operation, the engine stop/restart controller causes the automatic transmission to initiate a transfer to the special mode before fuel supply is interrupted and causes the forward clutch to completely engage at a specific point in time after the automatic transmission has completed the transfer to the special mode.
