【摘要】 行驶工况对于新车型的技术研发与认证、车辆污染物排放特性与燃料经济性分析以及交通控制水平风险评估等方面研究具有重要价值。为了开发与建立适合中国城市混合交通实际状况的车辆行驶工况,在归纳国内外大量研究文献的基础上,系统介绍了美国、欧洲和日本的典型行驶工况特点及其适用范围,重点分析了道路试验设计、数据解析技术与工况构建方法等行驶工况开发中的关键技术。最后,针对中国城市道路行驶工况研究提出下一步的研究方向与建议。更多还原

【Abstract】 Driving cycle research has an important value on the aspects of technical development and certification of new vehicle,vehicle’s pollutants emission characteristics and fuel economy analysis as well as risk evaluation in traffic control. In order to develop vehicle’ s driving cycle suitable for the actual mixed traffic situation of urban roads,the typical driving cycles and its applicable scope in U. S. A,ECE and Japan was introduced systematically based on inducing a large number of literatures. And the key technology such as road test design,data processing technology and construction method in driving cycle development were analyzed. Finally,aiming at the research on driving cycle of Chinese city,the future research directions and suggestion were put forward.更多还原
