The invention discloses a locomotive automatic driving redundant braking system and a graded braking safety control method. The locomotive automatic driving redundant braking system comprises an electrical control redundant system and an air braking loop redundant system. The electrical control redundant system is connected with the air brake loop redundant system; the electrical control redundant system is used for controlling the air brake loop redundant system; the electrical control redundancy system is composed of an original vehicle microcomputer, a vehicle control unit and an automatic driving protection host. The original vehicle microcomputer, the vehicle control unit and the automatic driving protection host are three independently-powered control systems, and when any one control system fails, the other control systems can independently control the locomotive to brake; the air brake loop redundant system is used for achieving small brake braking, large brake braking and emergency braking. According to the invention, safe braking of the locomotive during automatic driving can be realized, rich braking functions and higher redundancy are realized, the locomotive can be effectively protected, and the system safety of the locomotive is ensured.

    本发明公开了一种机车自动驾驶冗余制动系统及分级制动安全控制方法,该机车自动驾驶冗余制动系统包括电气控制冗余系统和空气制动回路冗余系统;电气控制冗余系统与空气制动回路冗余系统连接;电气控制冗余系统用于控制空气制动回路冗余系统;电气控制冗余系统由原车微机、控车单元和自动驾驶防护主机组成;原车微机、控车单元和自动驾驶防护主机是三个独立供电的控制系统,任意一个控制系统失效,其余的控制系统均可独立控制机车制动;空气制动回路冗余系统用于实现小闸制动、大闸制动和紧急制动。本发明能够实现自动驾驶时机车的安全制动,具有丰富的制动功能和较高的冗余度,能够对机车进行有效防护,确保机车的系统安全。
