Patent ID: 8152671

Claim:
A hybrid powertrain for a vehicle comprising: a prime mover; a transmission having an input member configured for connection with the prime mover to receive torque from the prime mover; an output member; a stationary member; a first motor/generator and a second motor/generator; a first planetary gear set and a second planetary gear set, each having a respective first member, second member, and third member; wherein the input member and the prime mover are continuously connected for common rotation with the first member of the second planetary gear set; wherein the second motor/generator is connected for common rotation with the second member of the second planetary gear set; wherein the first motor/generator is connected for common rotation with the first member of the first planetary gear set; wherein the second member of the first planetary gear set is continuously grounded to the stationary member; wherein the third member of the first planetary gear set and the third member of the second planetary gear set are connected for common rotation with the output member; and only one clutch; wherein the clutch is selectively engagable to ground the input member and the first member of the second planetary gear set to the stationary member.
