Zusammenfassung:	A transmission includes a first motor/generator with a first rotor connected for rotation with a first member of a first planetary gear set. A second electric motor/generator has a second rotor connected for rotation with a second member of the first planetary gear set. The second member of the first planetary gear set is connected for common rotation with the output member. The first member of a second planetary gear set rotates with the input member, and the third member of the second planetary gear set is grounded to a stationary member. A first torque-transmitting mechanism establishes torque flow between the first member of the second planetary gear set and the third member of the first planetary gear set. A second torque-transmitting mechanism establishes torque flow between the second member of the second planetary gear set and the third member of the first planetary gear set.
