Abstract

A powertrain includes a first planetary gearset configured to establish a fixedly linear speed relationship among a first rotor, an engine crankshaft, and a second rotor. The powertrain further includes a gearing assembly configured to alternately selectively establish a plurality of proportional speed relationships between the second rotor and an output shaft. The gearing assembly further includes a second planetary gearset having a lockup clutch configured to selectively couple two rotatable elements of the second planetary gearset.
