    摘要: A multi-speed transmission for a vehicle is provided with a selectable one-way braking clutch (SOWBC). The transmission has multiple planetary gear sets. Multiple torque-transmitting mechanisms are engagable in different combinations to establish at least one reverse speed ratio and multiple forward speed ratios between an input member and an output member. A selectable one-way braking clutch is configured to brake in one rotational direction and is selectively reversible to brake in an opposite rotational direction, and freewheels in some speed ratios.

    摘要: A method optimizes a fill event of an apply chamber of a fluid-actuated clutch, and includes determining input values describing the fill event, and then estimating a fill time using the input values. The method includes filling the apply chamber using the estimated fill time (EFT) or within an allowable range of the EFT. The input values can include a command line pressure, command fill stroke pressure, and an estimated viscosity of the fluid, although other values can be used. The input values are processed through a neural network having an input layer, an optional hidden layer, and an output layer. An assembly includes a fluid-actuated clutch having an apply chamber and a controller operable for estimating the fill time required for filling the apply chamber, and for controlling the fill of the apply chamber within the EFT.

    摘要: A family of power transmissions have three planetary gearsets each of which have first, second, and third members. A pair of fixed interconnecting members establish continuous connections between a member of the first planetary gearset and a member of the second planetary gearset, and between another member of the second planetary gearset and a member of the third planetary gearset, respectively. Each of the transmission family members has an output shaft, which is continuously connected with at least one member of one of the planetary gearsets and an input shaft, which is selectively connectible with at least two members of the planetary gearsets through respective first and second torque-transmitting mechanisms. Four other torque-transmitting mechanisms are provided to establish various interconnections between members of the planetary gearsets and/or members of the planetary gearsets and the transmission housing. The six torque-transmitting mechanisms are selectively engageable in combinations of four to establish at least seven forward speed ratios and one reverse speed ratio between the input shaft and the output shaft through the planetary transmission.
