插电式混合动力汽车能量管理策略研究现状和发展趋势

Current situation and development trend of plug-in hybrid electric vehicle's energy management strategies

目前国内外学者对插电式混合动力汽车能量管理策略进行了较为广泛和深入的研究,取得了良好的节能减排效果,为进一步提升其性能,有必要对插电式混合动力汽车能量管理策略的研究现状进行总结并对其发展趋势进行分析。首先对插电式混合动力汽车动力源能量流分配方法进行了归纳和分析,指出了当前插电式混合动力汽车能量管理策略两个亟待解决的问题:未考虑发动机冷却液温度和三元催化器温度等温度因素对油耗和排放影响;当前插电式混合动力汽车能量管理策略是以行驶功率需求作为输入,忽略了驾驶室制冷/供暖功率需求。最后提出了计及发动机冷却液温度和三元催化器温度等温度因素的能量管理策略和计及驾驶室制冷/供暖功率需求的能量管理策略两个未来研究方向。

Domestic and foreign scholars has extensively and deeply researched into plug-in hybrid electric vehicle＇s energy management strategies, and good results of energy saving and emission reduction has been achieved. In order to further improve the performance of plug-in hybrid electric vehicle, it is necessary to summarize the research status of its energy management strategies and analyze its development trend. Firstly, we summarized and analyzed the power source＇s energy flow distribution method of plug-in hybrid electric vehicle, and then pointed out two problems that needed to be solved in the current plug-in hybrid electric vehicle＇s energy management strategies. The first problem is the influence of engine coolant temperature and catalytic converter temperature on fuel consumption and emission isn＇t considered, and the second one is the current energy management strategies only take drive power demand as input and the cab cooling/ heating power demand is ignored. Finally, two future research directions were proposed. The first direction is the energy management strategy integrating engine coolant temperature and ternary catalytic converter temperature, and the second one is the strategy integrating cab＇s cooling/heating power demand.
