ABSTRACT:
A hybrid transmission includes first and second differential devices each including first, second and third rotating elements. An input element clutch is arranged to selectively connect the first rotating element of the first differential device and the first rotating element of the second differential device. An input member is arranged to connect an engine with the first rotating element of the second differential device. A first output member is connected with one of the first rotating elements of the first and second differential devices. A second output member is connected the second rotating element of the second differential device. A first motor/generator is connected with the second rotating element of the first differential device. A second motor/generator is connected with the third rotating element of the first differential device. One of a connecting state, a disconnect state, a reverse enable state and a unitary rotatable state is selectively selected by a select device.
