Abstract

A new hybrid-drive system taking flywheel energy storage system instead of chemical battery as assistant power source for hybrid electric vehicle is put forward. According to the particular energy characteristics of flywheel system, an energy management strategy based on fuzzy logic control is also developed with overall consideration on the optimization of both ICE (Internal Combustion Engine) and ISG (Integrated Started Generator). The strategy determines the optimal torque distribution between ICE and ISG through inputs of rotary speed of flywheel, rotary speed of ICE crankshaft and travel of accelerator pedal or brake pedal. Simulation results indicate that flywheel energy storage system is quite suitable for hybrid electric vehicle and with fuzzy logic control strategy both the performance of ICE and ISG are optimized that reduces fuel consumption of vehicle to greater extent.
