Abstract: Truck platooning is one of the important research directions for intelligent freight transportation. Taking the load action of truck platooning as the research object, the measured projects of truck platooning at home and abroad were surveyed and summarized on the basis of defining the transverse and longitudinal control modes of truck platooning. Based on the measured data of AUTOPILOT project, the transverse and longitudinal load distribution characteristics of truck platooning were analyzed respectively, and on this basis, the influence of axle load on truck platooning was analyzed. The results show that the standard deviation of transverse distribution of wheel tracks of truck platooning is 7.14 cm, which is only 1/3 of that of the traditional truck, and has obvious "channeled" characteristics. When the truck platooning travels at a speed of 100 km/h, the headway can be lower than 0.8 s, which is about 27% of that of the traditional truck at the same speed. Compared with traditional trucks, the number of axle load actions during truck platooning has the characteristic of "high frequency", which puts forward higher requirements for the fatigue resistance of existing pavement structures.

摘要： 货车编队技术是货运交通智能化的重要研究方向之一。以货车编队的荷载作用为研究对象，在明确货车编队的横向、纵向控制模式的基础上，调研并总结了国内外货车编队的实测项目；基于AUTOPILOT项目的实测数据，分析了货车编队的横向和纵向荷载分布特征，并在此基础上分析了货车编队的轴载作用影响。结果表明：货车编队的轮迹横向分布标准差为7.14 cm，仅为传统货车的1/3，具有明显的“渠化”特征；货车编队在以100 km/h的速度行驶时，车头时距可低于0.8 s，约为相同速度下传统货车的27%；与传统货车相比，货车编队运行轴载作用次数具有“高频”特性，对现有路面结构的抗疲劳性能提出更高的要求。
