    Abstract: A powertrain is provided that includes a hybrid transmission with an input member, an output member, and a stationary member, and a first and a second electric machine. Only a single planetary gear set having a first member, a second member, and a third member is operatively connected between the input member and the output member. The first, the second, and the third members include a ring gear member, a sun gear member, and a carrier member. The powertrain includes a first, a second, a third, and a fourth selectively engageable torque-transmitting mechanism. Selective engagement of a different one or ones of the torque-transmitting mechanisms and selective operation of one or both electric machines establishes a series operating mode, an input-split operating mode, at least one electric-only operating mode, and at least one fixed gear operating mode between the input member and the output member.

    Abstract: A vehicle includes an engine, fraction motor, final drive assembly, battery pack, and a supercapacitor module electrically connected to the battery pack. The vehicle also has first and second clutches and a controller. The clutches have opposite apply states. The first clutch connects an engine driveshaft to the motor to establish a neutral-charging mode. The second clutch connects an output shaft of the motor to the final drive assembly to establish a drive mode. The controller selects between the drive and neutral-charging modes in response to input signals. The drive mode uses energy from the supercapacitor module and battery pack to power the traction motor. The neutral-charging mode uses output torque from the engine to charge the supercapacitor module and battery pack. The clutches may be pnemauically-actuated, and the vehicle may be characterized by an absence of planetary gear sets.
