Hopefully useful description.
Full Hybrid vehicles combine functions of both series and parallel hybrid systems, and have the ability to move the vehicle with power from the IC engine, the electric motor, or a combination of both. The actual contribution from each power source depends on vehicle design and mode of operation. The engine can drive a generator to supply power to both the electric motor and the high voltage battery, or supply power to the drive wheels in conjunction with the electric motor.
The full hybrid has a motor/generator (MG1) attached directly to the engine, and a second motor/generator (MG2) attached directly to the drive wheels. The engine, MG1, and MG2 are interconnected through a compound planetary gear set. This allows the control module to direct power from the engine or both motor/generators as required. The 2007 Altima Hybrid is a full hybrid.
