Abstract: A hybrid transmission is provided that is configured to shift between the hybrid series operating mode and the compound-split operating mode synchronously, without slipping any torque-transmitting mechanisms. The transmission includes an input member operatively connected with the engine, an output member, and a plurality of selectively engageable torque-transmitting mechanisms. A gearing arrangement and first and second motor/generators operatively connected with the gearing arrangement are also provided. A first of the torque-transmitting mechanisms is engaged to establish a hybrid series operating mode between the input member and the output member, and a second of the torque-transmitting mechanisms is engaged to establish a compound-split operating mode between the input member and the output member. The shift between the hybrid series operating mode and the compound-split operating mode is synchronous without slipping the torque-transmitting mechanisms and occurs while the engine is on.

Abstract: 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.

Abstract: A hybrid powertrain for a vehicle having a disconnect clutch located between an internal combustion engine, or other power source, and a hybrid transmission. When deactivated, the disconnect clutch decouples the engine from the hybrid transmission, which enables the hybrid transmission input shaft to rotate independently of the internal combustion engine. This enables enhanced electric drive performance for the hybrid transmission. The disconnect clutch provides for internal combustion engine starting, including internal combustion starting at high vehicle speeds.
