摘要
给出了西安市纯电动城市客车行驶工况开发的流程、路线、数据采集及合成方法,合成出西安市纯电动城市客车综合行驶工况(XiBUS)。基于主成分分析与聚类分析法,解析西安市纯电动城市客车拥堵行驶、一般行驶、通畅行驶3类典型代表工况,分析了西安市纯电动城市客车综合行驶工况及ECE(Economic Commission for Europe)工况与试验数据总体之间的误差,将合成的西安市纯电动城市客车工况与ECE工况做了仿真对比分析,并将西安市纯电动城市客车行驶工况与典型城市工况做了对比分析。结果表明,合成的西安纯电动公交工况(XiBUS)误差最小,更接近西安市纯电动城市客车实际工况,ECE工况误差较大,不能反映西安纯电动城市客车实际工况;XiBUS工况与ECE工况差别较大,XiBUS比ECE工况对客车的能耗要求更高。
In this paper ,pure electric bus driving cycle in Xi’an (XiBUS) was developed .Based on Principal Component Analysis (PCA) and cluster analysis ,three typical driving cycle conditions (crowded traffic ,normal traffic and smooth traffic) of XiBUS were identified .The errors between XiBUS and Economic Commission for Europe (ECE) driving cycle were also analyzed .Simu‐lation results of BYD‐K9 under XiBUS and ECE conditions were presented .In addition ,a comparative analysis between XiBUS and other typical urban conditions were proposed .The analysis results showed that the driving cycle of the paper was more con‐sistent with the characteristics of urban traffic in Xi’an .
