摘要: 以串联混合动力汽车为研究对象,采用“系统建模-策略开发-仿真验证”的思路对能量管理策略进行了研究,建立了动力系统各关键部件的模型.将功率分配系数作为控制变量,以燃油经济性作为控制目标建立了一种基于逻辑门限与模糊算法的能量管理策略;以US06作为循环工况,在MATLAB/Simulink平台下进行了仿真,结果表明,所提出的能量管理策略正确有效,可以实现良好的燃油经济性,与传统的开关式能量管理策略相比,可以降低油耗113%.

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
