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.

摘要： A powertrain for a vehicle includes an engine, a transmission with an input member driven by the engine, and an output member. An electric motor is operable to drive the input member. The transmission has an electrically-actuated one-way clutch with a neutral mode in which the clutch freewheels in both directions of rotation, and a locked mode in which the clutch is locked in one direction of rotation. The transmission also has a hydraulically-actuated dual-piston clutch with a spring that biases the dual-piston clutch to an engaged state. The one-way clutch is in the neutral mode and the spring biases the dual-piston clutch to the engaged state prior to a key start of the engine. The one-way clutch is actuated to the locked state following ignition of the engine after a key start, and remains in the locked state during an autostop of the engine.

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 for controlling a torque converter having an internal lockup clutch includes detecting vehicle operating conditions and executing one of a stored plurality of torque converter clutch modes each corresponding to a different set of vehicle operating conditions. A fully-released mode corresponds to vehicle pre-launch, a partially-engaged mode corresponds to post-launch of the vehicle in first gear, downshift, coasting, throttle tip-in, or throttle tip-out; a first fully-engaged mode corresponds to steady-state operation in second gear or a higher; and a second fully-engaged mode corresponds to an upshift. Slippage across the converter is controlled only during the first fully-engaged mode. A vehicle is also provided having an engine, transmission, torque converter with lockup clutch, and controller having a control algorithm. The algorithm executes a different lockup clutch mode based on the detected vehicle operating conditions, and the slippage across the converter is controlled during only one lockup clutch mode.
