摘要： A transmission for a vehicle includes a first gear set and a second gear set. A first plurality of elements are operable in an applied state and a released state and a second plurality of elements are operable in an applied state and a released state. A controller toggles the first and second plurality of elements between the applied state and the released state to achieve a desired gear ratio. The controller times entry of at least one of the first and second plurality of elements into the released state with entry of at least another of the first and second plurality of elements into the applied state by controlling a hold pressure applied to the at least one element entering the released state. The controller determines the hold pressure by referencing current operating conditions of the transmission in a lookup table stored in a memory of the controller.

摘要： An automatic transmission for a vehicle includes a multi-plate clutch having an applied state and a released state and an overrunning clutch having an engaged state and an overrunning state. In addition, the transmission includes a controller that effectuates a gear shift of the transmission by applying a volume of fluid to the multi-plate clutch to toggle the multi-plate clutch from the released state to the applied state at approximately the same time the overrunning clutch is toggled into the overrunning state. The applied volume of fluid at which the multi-plate clutch is applied is substantially given by the following equation: VF=VL−(k*T) where VF is the volume, VL is the instantaneous volume at any time, k is a constant, and T is the input torque to the transmission.

摘要： A method of determining a fill volume of a clutch of an automatic transmission. A clutch fill sequence is observed from measurement of fluid pressure applied to the clutch, wherein the sequence may include a initial rise, a plateau, and a final rise. A fill end time may be identified as corresponding to an intersection of a forward extrapolated portion of the plateau and a backward extrapolated portion of the final rise.

摘要： A transmission includes an input shaft, an output shaft, a first plurality of gears, a second plurality of gears, and a series of engagement elements operable between an engaged position and a disengaged position. A controller is further provided to selectively toggle the series of engagement elements between the engaged position and the disengaged position to selectively couple one of the first plurality of gears or one of the second plurality of gears to the input shaft and the output shaft. The series of engagement elements sequentially couples the first plurality of gears to the input shaft and the output shaft during operation of the transmission and selectively couples one of the first plurality of gears or the second plurality of gears to the input shaft and the output shaft during a downshift operation of the transmission.

摘要： A method of double-downshifting from a first gear ratio to a second gear ratio includes the steps of first reducing torque transfer from a first clutch to a first driven gear. Engine speed then increases. Next, torque transfer from a second clutch to a third driven gear is increased while simultaneously the first clutch is disengaged from the first driven gear. Torque transfer from the second clutch to the third driven gear is then reduced. Torque transfer from the second clutch to the third driven gear is next increased. The first clutch is engaged to the second driven gear. Then, torque transfer from the first clutch to the second driven gear is increased while simultaneously the torque transfer from the second clutch to the third driven gear is reduced. Finally, the second clutch is disengaged from the third driven gear.
