The invention discloses a backup control method, device, equipment and medium for a redundant backup system, the redundant backup system for an autonomous vehicle domain controller at least comprises two MCUs, an isolation chip is arranged between the two MCUs, the isolation chip is used for isolating interference signals, and the isolation chip is connected with the MCU. The method comprises the following steps: monitoring whether communication between two MCUs is abnormal or not; and if one of the two MCUs is monitored to be abnormal, switching to the MCU which is not abnormal to continue communication, and isolating an interference signal generated by the abnormality through an isolation chip. According to the backup control method provided by the invention, the dynamic switching between the master control MCU and the backup control MCU is realized by monitoring the communication condition between the two MCUs; and meanwhile, mutual communication and mutual monitoring between the two MCUs are realized, and the two MCUs are isolated from each other and do not interfere with each other, so that the stability and the security level of the system are improved.
本申请公开了一种冗余备份系统的备份控制方法、装置、设备及介质,用于自动驾驶车辆域控制器的冗余备份系统,冗余备份系统至少包括两个MCU,在两个MCU之间设置隔离芯片,隔离芯片用于隔离干扰信号,所述方法包括:监测两个MCU之间的通信是否异常;如果监测到两个MCU的其中一个MCU发生异常,则切换到未发生异常的MCU继续通信,且通过隔离芯片隔离由异常产生的干扰信号。本申请提出的备份控制方法通过监测两个MCU之间的通信情况,实现了主控与备控MCU之间的动态切换;同时,实现了两个MCU之间的相互通信、相互监控,而且使得两个MCU之间相互隔离、互不干扰,进而提高了系统的稳定性及安全等级。
