The invention provides a method and a device for determining vehicle function safety. The method comprises the following steps: if BSM information sent by a target vehicle running in the same direction on an adjacent lane is received; defining related items; wherein the related items comprise function definitions and system elements; performing failure definition on the function of the related item based on a preset guide word by adopting a danger and operability HAZOP analysis method to obtain a function failure result; performing hazard analysis and risk assessment on the function failure result through the severity, the exposure probability and the controllability to obtain an automobile safety integrity level ASIL; exporting a safety target according to the automobile safety integrity level ASIL; and deriving a functional security demand (FSR) according to the security target. According to the method, by defining functions and systems between the vehicles, the function safety requirements of communication between the vehicles are defined in a unified manner, so that the levels of the function safety requirements between the vehicles are consistent, and the safety of the vehicles during lane changing is improved.
本发明提供了一种车辆功能安全的确定方法与装置,包括:如果接收到相邻车道同向行驶的目标车辆发送的BSM信息;定义相关项;其中该相关项包括:功能定义以及系统元素;采用危险与可操作性HAZOP分析方法,基于预设的引导词对该相关项的功能进行失效定义,得到功能失效结果;通过严重度、暴露概率以及可控性对该功能失效结果进行危害分析和风险评估,得到汽车安全完整性等级ASIL;根据该汽车安全完整性等级ASIL,导出安全目标;根据该安全目标导出功能安全需求FSR。该方法通过定义车与车之间的功能和系统,使车与车之间通信的功能安全要求统一定义,从而使车辆之间的功能安全要求级别一致,以提升了车辆变道时的安全性。
