摘　　要：针对地铁车辆在运行过程中,由于空气制动的短暂介入,导致制动缓解指示灯闪灭的问题,文章通过分析故障工况下车辆的制动过程和对控制逻辑进行解析,找出空气制动介入的原因,并提出对制动级位信号控制逻辑和电制动力管理过程进行优化的方案。通过在国内某地铁项目上的测试和验证表明,此方案可有效解决该问题,确保了车辆的正常运营。Aiming at the problem that the indicator light flashes off for release of brake due to the brief intervention of pneumatic brake during the operation of metro vehicles,this paper finds out the causes of the intervention of pneumatic brake by analyzing the braking process of vehicles under fault working conditions and the control logic,and presents a scheme to optimize the control logic of braking level signal and the process of electric brake force management.Through the test and verification in a domestic metro project,this scheme can effectively solve the problem and ensure the normal operation of vehicles.
