The invention provides a vehicle safety detection method, a vehicle safety detection device and a vehicle system. The method comprises the following steps: acquiring an initial hazard event of a vehicle; determining whether the initial hazard event is acceptable or not according to the first severity, the first controllability and the first frequency; under the condition that the initial hazard event is unacceptable, obtaining an initial measure corresponding to the initial hazard event, and improving the system performance limitation by adopting the initial measure to obtain a processed hazard event; determining whether the initial measure is valid according to the second severity of the processed hazardous event, the second controllability of the processed hazardous event and the second frequency of the processed hazardous event; and under the condition that the initial measure is invalid, updating the initial measure, so that the updated initial measure is valid, and obtaining an updated measure. The method solves the problem that in the prior art, effectiveness evaluation of expected function safety measures is not objective enough.
本申请提供了一种车辆的安全检测方法、车辆的安全检测装置以及车辆系统,该方法包括:获取车辆的初始危害事件;根据第一严重度、第一可控度以及第一频度,确定初始危害事件是否可接受;在初始危害事件不可接受的情况下,获取初始危害事件对应的初始措施,并采用初始措施对对系统性能局限进行改进,得到处理后危害事件;根据处理后危害事件的第二严重度、处理后危害事件的第二可控度以及处理后危害事件的第二频度,确定初始措施是否有效;在初始措施无效的情况下,对初始措施进行更新,以使更新后的初始措施有效,得到更新措施。该方法解决了现有技术中的预期功能安全措施的有效性评估不够客观的问题。
