Abstract

A transmission includes a first motor/generator having a first rotor that is selectively rotatable about a first axis and a second motor/generator having a second rotor that is selectively rotatable about a second axis. A first planetary gearset and a second planetary gearset each has a respective first planetary member, a respective second planetary member, and a respective third planetary member. One of the members of the first planetary gearset is operatively connected to the first rotor to receive torque therefrom. One of the members of the second planetary gearset is operatively connected to the second rotor to receive torque therefrom.
