The invention relates to a fault processing method and device for a vehicle-mounted controller with an end-to-end redundant structure, and the method comprises the steps: S1, a non-master control end transmits the operation state information of the end to a master control end in real time, and the master control end receives the state information of the non-master control end and comprehensively judges whether the vehicle-mounted controller has a fault or not in combination with the state information of the non-master control end; s2, judging whether a single-end fault occurs or not, if so, executing the step S3, and if not, executing the step S3; s3, the main control end sends the fault information to an ATS subsystem; s4, after receiving an automatic restart command sent by the ATS subsystem, the main control end performs logical judgment, and when the conditions that the running state of the non-main control end is abnormal and the ATS restart command is received are met at the same time, a process restart command is sent to the non-main control end; and S5, after the non-master control end receives the process restart instruction sent by the master control end, the stopped non-master control end is restarted under the condition of uninterruptible power supply. Compared with the prior art, the method has the advantages of really realizing uninterruptible power restart and the like.
本发明涉及一种首尾冗余结构的车载控制器故障处理方法及装置,所述方法包括:步骤S1,所述非主控端向主控端实时发送本端运行状态信息,所述主控端接收非主控端状态信息并结合自身状态信息,综合判断车载控制器是否存在故障;步骤S2,判断是否为单端故障,若为是,执行步骤S3;步骤S3,所述主控端将故障信息发送给ATS子系统;步骤S4,所述主控端接收ATS子系统发送的自动重启命令后,进行逻辑判断,当同时满足非主控端运行状态异常和收到ATS重启命令条件下,向非主控端发送进程重启指令;步骤S5,非主控端收到主控端发送的进程重启指令后,在不断电的情况下将已经停止的非主控端进行重新启动。与现有技术相比,本发明具有真正实现了不断电重启等优点。
