摘要/Abstract

摘要： 针对插电式混合动力客车,提出基于等效因子优化的实时能量管理策略。首先,设计了一种等效因子快速计算方法,先根据车辆的动力参数确定等效因子的取值范围,再应用射击算法快速计算等效因子。随后,提出了一种基于电池荷电状态(SOC)线性下降的自适应等效燃油消耗控制策略,利用车辆全球定位系统提供的车辆位置信息,通过在线更新等效因子,实现对参考SOC的实时跟踪。最后,与基于规则的控制策略和标准的ECMS控制策略进行仿真对比,结果表明:无论是在燃油经济性上还是在SOC控制的鲁棒性上,基于等效因子优化的策略都具有最好的控制效果。

Abstract: A real-time energy management strategy based on equivalent factor optimization is proposed for a plug-in hybrid electric bus (PHEB). Firstly, a fast calculation method of equivalent factor (EF) is designed, in which the range of EF is determined first according to the power parameters of vehicle, then the EF is quickly calculated by shooting algorithm. Next, an adaptive equivalent fuel consumption minimization strategy (A-ECMS) based on linear decline of battery state of charge (SOC) is proposed, and by utilizing the vehicle position information provided by the vehicle global positioning system (GPS) to update the equivalent factor online, the real-time tracking of reference SOC is achieved. Finally, a comparative simulation on A-ECMS is conducted against rule-based strategy, standard ECMS and dynamic programming strategy, and the results show that the A-ECMS proposed based on equivalent factor optimization has best control effects in both fuel economy and robustness of SOC control
