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 normally-engaged clutch is provided having a friction-element with a first side and an opposing second side, a first plate configured for pressing against the friction-element on the first side, and a second plate configured for pressing against the friction-element on the second side. The clutch also includes a biasing device configured to apply a first force to the second plate for pressing the second plate against the friction-element to engage the clutch. Additionally, the clutch includes an apply piston for applying a second force to the first plate, and a release piston for applying a third force to the second plate. The clutch is disengaged when the second plate is pushed away from the friction-element by the third force in the absence of the second force, and is engaged when the first plate is pressed against the friction-element by the second force.
