    摘要： A torque transmitting system includes a case, first and second clutch plates, and a ramp member that is selectively rotatable about an axis and that defines a ramp surface. The system also includes an electric motor having a motor housing, wherein the case is rotatable relative to the housing about the axis. The motor is configured to selectively apply torque to rotate the ramp member. The system additionally includes a roller element mounted with respect to the case and contacting the ramp surface. The ramp surface is configured such that, when the ramp member is rotated about the axis, the roller element exerts a reaction force on the ramp surface that urges the ramp member to move in a first axial direction and thereby transmit the reaction force to the clutch plates. A transmission assembly including the above described torque transmitting system is also disclosed.

    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 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 method is provided for controlling engagement of a clutch which carries torque before, during and after a shifting event in a transmission which is connected to a throttle-controlled engine. The method includes providing a feed forward input command which increases as the engine torque increases and decreases as the engine torque decreases. A feed-back input command is provided as a function of the error between measured clutch slip and a reference slip profile. The feed-forward input command and feed-back input command are summed to provide a clutch control command for controlling engagement of the clutch before, during and after the shifting event to allow a desired amount of clutch slip to damp excitation of the transmission.
