摘　　要：全自动运行系统基于无人驾驶前提下,针对露天/高架线路在雨雪天气下,因轨面湿滑可能发生列车空转打滑影响行车场景,制定雨雪模式控车,降低列车空滑风险。然而,雨雪模式下大幅降低列车限速,会对线路运营效率产生较大影响,不能有效满足运营使用需求,也是线路运营部门实际使用雨雪模式时迫切痛点。该文针对北京典型全自动运行线路燕房线(露天高架线路),对全自动运行系统雨雪模式下限速提升进行分析研究,在保证系统控车安全前提下,制定雨雪模式限速提升有效解决方案,为后续全自动运行系统线路雨雪模式提升运营使用可用性提供借鉴。The fully automatic operation control system is based on the premise of unmanned driving,and is designed to reduce the risk of train slip in rainy and snowy weather on outdoor/elevated lines due to the possibility of train slip due to wet track surface,which may affect driving safety.A dedicated rain and snow mode control system is developed to reduce the risk of train slip.However,significantly reducing the train speed limit in rain and snow mode will have a significant impact on the efficiency of line operation and cannot effectively meet the actual operational needs.It is also an urgent pain point for line operation departments when using rain and snow mode in practice.This article focuses on the Yanfang line(an open-air elevated line),a typical fully automatic operation line in Beijing,and analyzes and studies the speed limit improvement in the rain and snow mode of the fully automatic operation system.While ensuring the safety of the system’s vehicle control,an effective solution for the speed limit improvement in the rain and snow mode is developed,providing reference for the future fully automatic operation system to improve the operational usability in the rain and snow mode of the line.
