摘要
以重型普通载货汽车为研究对象,针对用户使用情况进行了调研和实车试验,并应用数理统计和多参数统计理论主成分分析与聚类分析方法,解析出重型普通载货汽车典型用户行驶循环工况。基于所提取的循环工况进行了综合油耗的仿真分析,结果表明,仿真计算油耗与用户实际使用油耗一致,证明了所提取重型普通载货汽车整车行驶循环工况的正确性。
In this paper, driving cycle condition of typical user of heavy duty truck is obtained with mathematical statistics and main component analysis and cluster analysis of multi-parameter statistic principal, based on survey and vehicle test, with a heavy duty truck as research object. Simulation is made to combined fuel consumption based on the abstracted drive cycle, the ＇results show that the simulated fuel consumption is consistent with user＇s actual fuel consumption, proving correctness of the abstracted driving cycle of the heavy duty truck.
