摘　　要：基于昆明市新能源汽车示范运行管理信息化平台,对高原地区三种品牌的混合动力公交客车进行了示范运行数据采集,对运行车辆的油耗、车速、转速、负荷率进行了分析研究。结果表明:昆明市不同品牌车辆的高原示范运行适应性不同;示范运行车辆平均车速较低,且主要运行在40 km/h以下,怠速停车时间较长;示范运行车辆均在低转速、低负荷区运行时间最长,在中等转速、中等负荷区运行时间较短;根据高原地区实际工况特点,合理改善驾驶员操作习惯、优化车辆控制策略和发动机适配技术可提高车辆燃油经济性。On the basis of the new energy vehicles demonstrating run management informatization platform in Kunming,the demonstrating run data acquisition of 3 kind of hybrid buses in the plateau region was achieved,and the fuel consumption,speed,revolving speed and the load rate of the running vehicles were analyzed.The result shows that the different brands of buses have different adaptability.The average speed of these buses is slow and mainly less than 40 km / h,as well have a long time of idling stop.These different brands of buses have the longest running time when they run at the low speed and low load area,while less time at the medium speed and medium load area.According to the specified features of the working conditions in the plateau region,the combustion effciency of the buses can be improved if reasonably improving the drivers’operating habits,optimizing the strategy of vehicle controlling and adapting the appropriate engine adaption techniques.
