一种汽车工况构建中的数据预处理方法

A Method of Data Preprocessing in construction of Driving Cycle

为了构建西安市主城区混合动力公交车行驶工况,使用车载GPS采集仪对K36路公交车进行实时数据采集。对比采集到的车速—时间曲线与公交车实际运行情况,发现二者有较大出入。参考精度较高的GPS采集仪的结果,得出原因是采集设备的精度不够。为满足构建工况的要求,对异常数据进行修正处理,对修正的方法作以介绍。

In order to build driving cycle of hybrid bus in urban zone of Xian,use on-board GPS collection apparatus tocollect real-time data of K36bus.In the contrast of velocity-time curve and real driving condition,there are manydifferences between them.In the reference of result of GPS collection apparatus with higher accuracy,the reason iscollection apparatus’s accuracy is low.In order to satisfy requirement of driving cycle building,to amend abnormal data andintroduce the method of data amending.
