摘要： A multi-speed transmission for a vehicle is provided with a selectable one-way braking clutch (SOWBC). The transmission has an input member connected for common rotation with one of the members of four planetary gear sets and an output member connected for common rotation with another of the members of the planetary gear sets. Four interconnecting members connect different members of the planetary gear sets for common rotation. A first brake is selectively engagable to ground the first member of the first planetary gear set to the stationary member. A first, a second, and a third rotating clutch are each selectively engagable to connect a different respective pair of the members of the planetary gear sets for common rotation. 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 powertrain in a vehicle includes an electro-mechanical transmission having a selectable one-way clutch mechanically-operatively coupled to an internal combustion engine and configured to selectively transmit mechanical power to an output member. A control method includes monitoring a vehicle speed, monitoring a transmission gear state, comparing the vehicle speed to a threshold low speed range, transitioning a selectable one-way clutch into an engaged mode when said vehicle speed is not in a forward direction in excess of the threshold low speed range, and maintaining the selectable one-way clutch in the engaged mode based upon the transmission gear state remaining in a first gear state and the vehicle speed remaining within said threshold low speed range, a neutral state, or a reverse state.

摘要： A vehicle includes a powertrain having first and second rotatable members, speed sensors, and a controller. The speed sensors generate output signals encoding the speeds of the respective first and second rotatable members. The controller calculates a rotation angle of the members using the output signals and estimates a torque value in the powertrain as a function of the rotation angles. The sensors may count the teeth of respective first and second toothed gear elements and encode the count as the output signals. The controller may estimate the torque value as a function of a linear coefficient and the present gear ratio of the sensors. The controller may also detect a commanded upshift of the transmission and detect a fill event of an oncoming clutch of the transmission as a function of the corresponding rotation angles for the rotatable members. The members may be input, output, or intermediate members.
