A Hybrid Power Driving System with an Energy Storage Flywheel for Vehicles 2007-01-4114

This study generates a conceptual vehicle hybrid power driving system that consists of an internal combustion engine, a motor, two continuously variable transmissions, a generator, a pulse width modulation electric controller, a planetary gear, and an energy storage flywheel. The flywheel drives a generator that generates electric power for the motor to drive the vehicle. The controller with the fuzzy theory is used to determine the torque distribution of the engine and the motor. Using the Japanese 10-15 mode, the driving shaft torque, the engine torque, the motor torque, the torque distribution percentages of the engine and the motor and the flywheel angular velocity versus time were studied with the flywheel moment of inertia to be e 0.6 kg·m2 and 1.2 kg·m2 and the reduction speed ratio to be 0.231. The flywheel moment of inertia to be 1.2 kg·m2 is selected for the system to have more stable operation.
