Abstract
A multi-speed hybrid transmission includes a main gearset connected to a vehicle gas combustible engine and providing torque to an output shaft. The transmission also includes an electric drive unit comprising an electric motor that is selectably connectable to the output shaft to provide additional torque to the output shaft. When connected to the output shaft, the electric drive unit improves vehicle performance under certain driving conditions (e.g., high boost in low gear or in upper gears) while also improving fuel efficiency.
