针对人工分类的不足，研究了动态聚类法在车辆实际行驶工况开发中的应用。
Taking into account the deficiency of artificial classification, the purpose of this paper was to report the application of dynamic cluster to the development of vehicle real world driving cycle.
本文以科技部863课题“典型城市车辆实际行驶工况的研究”为依托，阐述城市车辆行驶工况的开发方法及相关研究。
The paper describes development method and relative research of vehicle driving cycle, according to 863 project-study of vehicle real driving cycles of typical city.
该方法采用动力学模型对车辆运动进行描述，考虑了车体运动与车轮速率、转向角之间的关系，比用线性模型更符合车辆实际行驶时的复杂运动状况。
For the mobile case, a dynamic model of the vehicle motion, which takes account of the relationship between the rigid body motion of vehicle and the steering and drive rates of wheels, is adopted.
