摘　　要：利用GPS车载测试系统对宜昌市轻型客车、轻型卡车、重型卡车和公交车等车型机动车行驶工况分别进行测试。基于测试结果,采用特征参数法合成了宜昌市机动车分车型行驶工况,分析了其特征并与欧美标准工况和5个不同规模城市的机动车行驶工况进行了对比。结果表明:宜昌市机动车行驶平均速度高于ECE15工况,低于FTP-75工况;怠速比例较欧美标准工况低7%～87%,减速比例较欧美标准工况高28%～129%。与其他不同规模城市相比,宜昌市轻型客车行驶的平均速度,怠速、匀速比例也表现出不同的特征。Urban motor vehicle driving patterns were monitored of cars,light trucks,heavy trucks and buses in Yichang City using a GPS instrument.Based on the test data,the driving cycles for different types of vehicles in Yichan City were simulated using the method of feature parameter.The characteristics of driving patterns in Yichang City were analyzed,and the main parameters were compared with those of European and American standard test cycles and driving cycles in 5 Chinese cities with different sizes.The results showed that the average speed of Yichang City＇s vehicles was higher than the ECE15,lower than the FTP-75;idling rates were 7%~87% lower than the standard driving cycles,and deceleration rates were 28%~129% higher.Compared to driving cycles of light-duty passenger car in Chinese other cities,average speed,idling rate and acceleration rate of Yichang City were significant different.
