Abstract
A powertrain includes an input member, an output member, and a stationary member. A first and a second electric motor/generator are provided. Only two planetary gear sets are used, each having a respective first, second, and third member. An interconnecting member connects one of the members of a first one of the planetary gear sets to one of the members of a second one of the planetary gear sets. The input member, the output member, the first motor/generator and the second motor/generator are each continuously connected for common rotation with a different one of the members of the planetary gear sets that is not connected by the interconnecting member. Four brakes are each selectively engageable to ground a different respective one of the members of the planetary gear sets that is not connected by the interconnecting member to the stationary member.
