The invention discloses a safety monitoring method and an automobile. The method comprises the steps that a first system state corresponding to a core monitoring system is monitored, when the first system state is an abnormal state, the core monitoring system executes reset operation, and a core recovery system executes a first recovery strategy; a second system state corresponding to the core recovery system is monitored, when the second system state is an abnormal state, the core monitoring system controls the core recovery system to execute restart operation, and the core recovery system executes a second recovery strategy; and monitoring a third system state corresponding to the sub-service system, and when the third system state is an abnormal state, executing a third recovery strategy by the core recovery system. The domain controller system reliably completes safety monitoring and quick recovery under the condition that system redundancy backup is not performed, the software and hardware cost is saved, and the fault recovery efficiency is guaranteed.
本发明公开一种安全监测方法和汽车。该方法包括:监测核心监测系统对应的第一系统状态,在第一系统状态为异常状态时,核心监测系统执行复位操作,核心恢复系统执行第一恢复策略;监测核心恢复系统对应的第二系统状态,在第二系统状态为异常状态时,核心监测系统控制核心恢复系统执行重启操作,核心恢复系统执行第二恢复策略;监测子业务系统对应的第三系统状态,在第三系统状态为异常状态时,核心恢复系统执行第三恢复策略。该域控制器系统在不做系统冗余备份的情况下,可靠地完成安全监测和快速恢复,节省了软硬件成本,保障其故障恢复效率。
