Abstract
A vehicle powertrain includes first and second power sources and a transmission assembly having first and second input members and an output member. The transmission assembly also includes a first multiple node planetary gear-set connected to both input members and a second multiple node planetary gear-set connected to the output member. The transmission assembly additionally includes a transmission housing retaining the first and second gear-sets. Furthermore, the transmission assembly includes a first torque-transmitting device for connecting one second gear-set node to the transmission housing and a second torque-transmitting device for connecting one first gear-set node to one second gear-set node. One first gear-set node is directly and continuously connected to one second gear-set node. The first and second power sources are connected to the first gear-set, and the first power source is connected to the first gear-set node not directly and continuously connected to the second gear-set.
