摘　　要：为兼顾智轨电车虚拟联挂编组行车的高效性与安全性,文章分析了汽车CACC与列车虚拟联挂跟车间距的控制方法,从智轨电车安全制动模型出发,考虑了车辆牵引/制动特性、车车通信延迟、控制器响应时间、测速相对误差等因素,详细推导出了联挂编组安全行车速度与最小安全追踪间距的数学模型;结合典型参数进行了定量仿真计算与分析,得出了运行安全防护的关键数据与优化措施,实现了联挂编组在0~60 km/h速度范围内跟车间距均可保证在10 m以下,能有效防止社会车辆加塞,在保障编组运行安全性的前提下进一步提升了线路运能,为智轨电车虚拟联挂的工程化系统设计与安全运行控制提供了坚实可靠的理论依据。In order to take into account the high efficiency and safety of the virtual coupling composition operation of the autonomous-rail rapid trams,the article analyzes the control method of the tracking distance between the CACC vehicle and the virtual coupling of the train.Vehicle traction/braking characteristics,vehicle-vehicle communication delay,controller response time,relative error of speed measurement and other factors are taken into account,and the mathematical model of safe traveling speed and minimum safe tracking distance for the coupling composition is deduced in detail;combined with the typical parameters,the quantitative simulation calculation and analysis are carried out,and the key data and optimization measures of operation safety protection are obtained,which realize that the tracking distance of coupling composition can be guaranteed to be below 10 m in the speed range of 0~60 km/h.This can effectively prevent the queue-jumping of social vehicles,further enhance the line capacity under the premise of guaranteeing the safety of coupling composition,and provide a solid and reliable theoretical basis for the engineering system design and safe operation control of the virtual coupling of autonomous-rail rapid trams.
