摘要
车辆队列行驶技术作为智能交通系统中的重要组成部分,在节能减排、优化交通状态、提高行驶安全等方面具有重大意义。优化车辆队列行驶的空气动力学性能,是提高其节能减排作用的重要手段之一。文章详细总结了车辆队列行驶的空气动力学研究内容,根据影响队列空气动力学性能因素的不同,将其分为队列内部因素(车与车)和队列外部因素(车与环境),其中,队列内部因素阐述和分析了车辆造型、速度、车辆数目、间距及队列形式对整体的气动性能影响;队列外部因素阐述和分析了自然环境和道路环境对整体气动性能的影响,同时梳理了每种因素的发展与研究现状。最后总结了车辆队列行驶中空气动力学研究的关键技术和发展趋势,为将来队列行驶的推广应用提供理论基础。
As an important part of intelligent transportation system,vehicle platoon technology has great significance in emission reduction,traffic optimization and safety improvement.Optimizing the aerodynamic performance of vehicle platoon is one of the important means to improve its energy saving and emission reduction.In this paper,the aerodynamic research of vehicle platoon is summarized in detail.Depending on the factors that affect the aerodynamic performance of the platoon,they are divided into internal factors(vehicle to vehicle)and external factors(environment to vehicle).Among them,the influences of vehicle shape,speed,number of vehicles,spacing and platoon form on the overall aerodynamic performance are described and analyzed.The influence of natural environment and road environment on the overall aerodynamic performance is expounded and analyzed.At the same time,the development and research status of each factor are reviewed.Finally,the key technologies and development trends of vehicle platoon aerodynamic research are summarized.The research results provide a theoretical basis for the promotion and application of queue driving in the future.
