系列化标准地铁车辆制动系统与全自动无人驾驶相关的功能需求分析

Analysis on Functional Requirements of the Braking System of Serialized Standard Metro Vehicles Related to Fully Automatic Unmanned Driving

为解决城市轨道交通列车在全自动无人驾驶运行模式下的安全导向或者对标超出停车精度的问题,系列化中国标准地铁列车研制及试验项目在制动系统功能规范制定过程中,规定了蠕动模式、跳跃模式、低黏着模式、空气制动远程隔离、制动系统重大故障反馈等与城市轨道交通全自动无人驾驶技术相关的功能需求。本文针对上述功能需求进行分析,可为后续系列化标准地铁车辆与信号系统的接口设计提供参考和借鉴。

In order to solve the problem that the safety guidance or benchmarking of urban rail transit trains exceeds the parking accuracy under the full-automatic unmanned operation mode,during the process of formulating the functional specification of the braking system,the development and test project of the serialized Chinese standard metro train stipulates the functional requirements related to the full-automatic unmanned driving technology of urban rail transit,such as creeping mode,jumping mode,low adhesion mode,remote isolation of air braking,and heavy fault feedback of the braking system,etc.This paper analyzes the above functional requirements,which can provide reference for the interface design of subsequent serialized standard metro train and signal system.
