planet gears meshed with the sun gear, and a ring gear with inward-facing
teeth that mesh with the planet gears. The engine is attached to the planet
carrier, the motor is coupled with the driveline shaft so that both are
attached to the ring gear, and the generator is mounted to the sun gear. Their
relationships are given by (Miller and Everett 2005):
