The embodiment of the invention provides a vehicle function safety monitoring method and system, and the method specifically comprises the steps: a vehicle function operation state is monitored, and a fault notification is reported to a fault jitter removal module when a fault occurs; the fault jitter removal module confirms a fault type; the fault management module starts an overtime timer to track a fault processing flow, and notifies a corresponding application software layer to perform fault preprocessing according to corresponding information of a fault table; and after the preprocessing is finished, the fault management module closes an overtime timer and triggers a fault state notification module to notify a corresponding fault processing module to carry out a function safety processing flow. According to the method, the requirements of real-time performance, independence and diversity in functional safety fault management work are met through a unified fault management process.
本发明实施例提出了一种车辆功能安全监控方法及系统,其中所述方法具体包括步骤为:监视车辆功能运行状态,并在故障发生时向故障去抖模块上报故障通知;所述故障去抖模块确认故障类型;故障管理模块启动超时定时器跟踪故障的处理流程,并根据故障表对应信息,通知对应的应用软件层进行故障预处理;预处理结束后,所述故障管理模块关闭超时定时器,并触发故障状态通知模块通知故障处理的对应模块,进行功能安全处理的流程。本发明通过统一的故障管理流程,满足了功能安全故障管理工作中的实时性、独立性和多样性的要求。
