Abstract
A hybrid powertrain for a vehicle includes a prime mover, which may be an engine, and a transmission that has an input member configured for connection with the prime mover to receive torque from the prime mover, an output member, and a stationary member. A first motor/generator and a second motor/generator are provided as additional motive sources. A first planetary gear set and a second planetary gear set are included, each having a respective first member, second member, and third member. Only one clutch is operatively connected to the transmission, and it is selectively engagable to ground the input member and the first member of the second planetary gear set to the stationary member.
