摘　　要：保持制动逻辑是动车组制动逻辑的重要组成部分,保障动车组制动系统的可靠运行。在实际运行过程中,由于运行线路存在一定坡道,动车组在坡道线路缓解保持制动的瞬间存在溜坡和冲动运行的风险,行车安全存在隐患。优化了动车组保持制动缓解控制逻辑,通过牵引变流器、网络系统和制动控制装置等设备协调配合,利用网络系统和指定控制装置对牵引力和速度的判断保证动车组坡起不溜车,通过冗余设计保证动车组的安全运行。Brake hold logic is an important part of the EMU brake logic which ensures the reliable operation of EMU brake system. In the actual operation process,the EMUs have the risk of slipping and impulsive running at the moment when relieving brake hold due to a certain ramp on the running line, existing potential safety hazard. The control logic of EMU brake hold release are optimized through the coordination and cooperation of traction converter, network system and brake control device,using the network system and the designated control device to judge traction force and speed to ensure no running away at ramp,and guaranteeing safe operation through redundant design.
