Abstract: Energy management strategy was researched for the series hybrid electric vehicle using system modelingstrategy developmentsimulation verification method, and models of the pivotal components of the powertrain system were built. Taking the power splitting coefficient as the control variable, an energy management strategy based on logic threshold and fuzzy algorithm was proposed for improving fuel economy. The US06 drive cycle was simulated in MATLAB/Simulink circumstance. The results showed that the proposed strategy is correct and effective for realizing better fuel economy. Fuel consumption can be reduced by 113% comparing with that of the traditional onoff strategy.

Key words: hybrid electric vehicle, energy management strategy, logic threshold, fuzzy control, simulation
