基于城市道路的车辆自行驶工况构建Constructing the Driving Conditions of the Vehicle Based on Urban Roads
郑恩娣
摘要(Abstract)：
通过对某一城市轻型汽车运行过程中收集到的数据进行预处理，并采用微分流形和笛卡尔坐标系转换的思想对采集数据进行统一。按照车辆运行状态和运动学片段道路实际坡度情况，采用K-均值聚类分析法对各运动学片段对应的行驶路段进行分类。分别对分类好的六种类型道路进行行驶工况模型的构造，根据运动时长分布规律对各工况模型进行汇总，得到基于该测试车辆自身行驶情况的行驶工况并证明可行性。该行驶工况可以很好的体现该地区的实际道路情况和人文环境。
关键词(KeyWords)： 车辆行驶工况;运动学片段;坡度;K-均值聚类分析
