摘要： 随着电动汽车技术的发展和综合性能要求的提高，辅助能量系统(Auxiliary power units，APUs，例如，空调系统、动力转向系统、制动系统、发动机冷却系统等)在混合动力汽车中发挥着愈来愈重要的作用。研究辅助能量系统在车辆行驶过程中的能量流变化，可进一步完善整车的综合能量流管理。分析APUs的工作特点，提出基于能耗map图的仿真思路，通过对ADVISOR软件的二次开发，设计APUs的仿真模型，分别建立传统公交车、串联混合动力和并联混合动力城市公交车的综合能量流模型，完善了传统汽车及HEV的仿真模型。在此基础上对APUs对整车经济性的影响进行仿真研究，仿真研究结果表明，电动汽车附件系统在整车能耗上占有相当的比重，在美国城市循环、ECE循环工况和武汉城市公交车循环工况下，公交车辅助能量附件系统能耗比例最大为10%、最小为6.1%。

Abstract: With the improvement of electric vehicle technology and higher requirement for integrated performance, auxiliary power units (APUs, such as air conditioning system, electric power steering system, braking system and cooling system, etc.) will play more and more important functions. The analysis of APUs’ energy flow change during vehicle running can consummate the energy flow management of full vehicle. The work characteristics of APUs is analyzed, APUs models are built by using ADVISOR software based on energy consumption map. The threetypes of APUs models adapt to the traditional bus, serial HEV and parallel HEV bus, which improve the vehicle model accuracy. Then the APUs’ economic effect on the full vehicle is simulated, the results indicate that APUs occupy quite a few proportion of the energy consumption in the vehicle. In the USA city cycle, ECE cycle and Wuhan city bus cycle, the energy consumption of APUs occupies 6.1%~10% of the whole consumption.
