摘　　要：分析了中国3个典型城市(北京、上海和广州)车辆行驶的速度、怠速、最大速度、加速度以及行程等特征及其分布特征;结合交通特性研究了车辆行驶运动学水平。研究表明,现行采用ECE15工况与实际行驶工况相比,车辆燃油消耗被低估约10%;覆盖的车辆工况范围远远小于实际行驶工况,不适用于车辆设计开发要求。The real driving cycles, including the features of driving speed, idling, maximum speed, acceleration and travel mileage, as well as their distribution features in three typical cities （Beijing, Shanghai and Guangzhou） of China are analyzed, using principal components analysis and cluster analysis. The study indicates that compared with real driving cycle, the ECE15 test cycle currently adopted under-estimates the car fuel consumption by around 10% , and covers far lesser driving modes, so not meeting the requirements of vehicle development.
