Abstract
A power-split hybrid powertrain for a vehicle includes a first power-source configured to generate a first output torque, a second power-source configured to generate a second output torque, and a transmission assembly having a transmission input member. The powertrain also includes a planetary gear-set having first, second, and third nodes, wherein each of the three nodes is operatively connected to a separate one of the first power-source, second power-source, and transmission input member. The powertrain additionally includes a housing configured to retain the planetary gear-set. Also, the powertrain includes a first torque-transmitting device configured to selectively connect to the housing the node that is operatively connected to the first power-source. Furthermore, the powertrain includes a second torque-transmitting device configured to selectively connect the node that is operatively connected to the first power-source to the node that is operatively connected to the second power-source.
