In semi-independent right-of-way operation mode, the driver’s driving style of a hydrogen fuel cell hybrid electric tram has a great impact on the vehicle’s operation economy by influencing the state of charge of the lithium battery. An adaptive energy management strategy combining drivers’ driving styles was proposed to improve the adaptability of the energy management strategy to working conditions and driving styles. First, considering the influence of different road conditions on drivers' driving styles, the K-means clustering algorithm was used to identify driving conditions, and driving conditions were divided into low-speed, medium-speed, and high-speed. The impact degree and the standard deviation of acceleration were introduced to construct the fuzzy logic algorithm to identify the driving style, and the driving style was divided into moderate, standard, and aggressive. Second, by taking the optimal instantaneous hydrogen consumption of the system as the objective function, under the premise of meeting the constraint conditions, the correction coefficient of the equivalent factor of the charged state of the lithium battery was introduced, and the corresponding equivalent factor in the traditional equivalent hydrogen consumption minimization strategy was adjusted according to different driving styles so as to realize the real-time change of the equivalent factor with the driving style. Finally, the proposed strategy was compared with the traditional Equivalent Consumption Minimization Strategy and Minimum Principle. The results show that the proposed strategy can achieve the optimal power distribution of the three power sources in the selected working conditions. Compared with the other two strategies, the charge state fluctuation curves of the lithium battery and supercapacitor are the smoothest. At the end of the driving range, the hydrogen consumption of the hybrid system is 1.39 kg, which has the best fuel economy. The maximum deviation rate of bus voltage is minimal, the three power sources are stable, and the system stability is strong. The research results provide a reference for further improving the driving adaptability of trams in actual operation. [ABSTRACT FROM AUTHOR] |

半独立路权运行模式下，氢燃料电池混合动力有轨电车驾驶员的驾驶风格影响锂电池荷电状态，从而对整车运行 经济性有较大影响。提出一种结合驾驶员驾驶风格的自适应能量管理策略，以提高能量管理策略对工况和驾驶风格的适应 性。首先，考虑不同的道路工况对驾驶员驾驶风格的影响，通过K-均值聚类算法对行驶工况进行识别，将行驶工况分为低 速、中速、高速3类；引入冲击度和加速度标准差构建基于模糊逻辑的算法，对驾驶风格进行识别，将驾驶风格分为迟钝 型、标准型、激进型3类。其次，建立系统瞬时氢耗量最优的目标函数，在满足约束条件的前提下，引入锂电池荷电状态 等效因子修正系数，针对不同驾驶风格调整传统等效氢耗最小策略中相应的等效因子，以实现等效因子随驾驶风格的改变 实时变化。最后，将该策略与传统等效氢耗最小策略、庞特里亚金极小值策略进行仿真对比分析，结果表明：该策略能实 现3个动力源功率分配最优；锂电池和超级电容荷电状态波动曲线相较于其他2种策略最为平滑；在续驶里程结束时混合动 力系统氢耗量为1.39 kg，具有最为优越的燃油经济性；母线电压最大偏移率最小；能使3个动力源平稳出力，具有较强的 系统稳定性。研究结果为进一步提高有轨电车实际运行中对驾驶风格的适应性提供参考。 [ABSTRACT FROM AUTHOR] |
