摘要

城市轨道交通（简称“城轨”）存在高峰期拥挤、平低峰期运力浪费的问题，能够根据客流实时变化动态调整线路运力的虚拟编组技术已逐渐成为轨道交通列车运行控制系统的发展方向和研究热点。介绍了虚拟编组列车的概念和整体研究现状，分析了对实现虚拟编组最重要的列车安全防护和运行控制两项关键技术的研究进展，并指出了仍需解决的关键问题和可能的解决方案。其中，在安全防护方面，现有方法虽普遍采用相对制动距离原则，但暂未对列车单元的时空关系进行分析，无法严格保证列车运行安全性。因此，针对性地提出了基于时空分隔的列车安全防护方法；在列车驾驶控制方面，既有研究大多仅关注站间稳定运行过程，而在城轨中尤为重要的列车进站过程及虚拟编组可能存在的停车不同步问题仍未得到充分关注，因此，指出该问题并提出基于协同控制的列车单元跟踪控制方法。本文可为读者了解城市轨道交通列车虚拟编组技术的发展趋势和投身相关研究提供参考。

Abstract

Metros have the problems of passenger crowding during the peak hours and waste of transport capacity during the non-rush hours. Virtual coupling (VC) is expected to be a good solution to this problem, by which train formation can be dynamically adjusted, thus the line capacity is adjusted. This paper introduces the concept and relevant research of VC, and the existing problems and possible solutions are presented. Train protection and operation control methods are two most important problems among them. For the former, although relative braking distance principle is adopted, the space-time relationship between successive trains is omitted, thus, a space-time-separation-based train protection principle is proposed in this paper; for the latter, most of the existing studies only focus on the cruising control of VC, while the problem of non-synchronous parking that exists in the process of VC arrival at a station is wrongly ignored, which is particularly important in metros, a cooperative-control-based train following method is presented to solve this problem. This paper can provide a reference for readers to understand the development trend of virtual coupling technology in metros and to engage in relevant research.

Key words： Metro; virtual coupling; train operation; train protection; cooperative control
