Abstract:
The hybrid powertrain has a plurality of members that can be utilized to provide eight forward speed ratios and one reverse speed ratio in a hybrid transmission architecture. The transmission includes three planetary gear sets having five torque-transmitting devices and four fixed interconnections. The powertrain includes an engine, a damper, a pump, an engine disconnect clutch, and a drive motor, all operatively connected with the transmission to provide strong hybrid operating capability.
