ABSTRACT:
An electro-mechanical powertrain has two motor/generator (m/g) units disposed in concentric coaxial arrangement with a plurality of planetary gearsets and a pair of friction brakes. An input shaft is driven by a prime mover through a selectively engageable clutch. The motor/generator units are controlled in combination with the planetary gearset, the prime mover and an electrical source (batteries) to provide a two-mode, input split powertrain.
