The scope of automotive functions has grown from a single vehicle as an entity to multiple vehicles working together as an entity, referred to as cooperative driving. The current automotive safety standard, ISO 26262, is designed for single vehicles. With the increasing number of cooperative driving capable vehicles on the road, it is now imperative to systematically assess the functional safety of architectures of these vehicles. Many methods are proposed to assess architectures with respect to different quality attributes in the software architecture domain, but to the best of our knowledge, functional safety assessment of automotive architectures is not explored in the literature. We present a method, that leverages existing research in software architecture and safety engineering domains, to check whether the functional safety requirements for a cooperative driving scenario are fulfilled in the technical architecture of a vehicle. We apply our method on a real-life academic prototype for a cooperative driving scenario, platooning, and discuss our insights.

汽车功能的范围已从作为实体的单个车辆发展为作为一个实体一起工作的多个车辆，称为协作驾驶。当前的汽车安全标准ISO 26262是为单车设计的。随着道路上具有协作驾驶能力的车辆数量的增加，现在必须系统地评估这些车辆的架构的功能安全性。提出了许多方法来评估软件体系结构领域中有关不同质量属性的体系结构，但是据我们所知，文献中并未探讨汽车体系结构的功能安全性评估。我们提出了一种方法，该方法利用了软件体系结构和安全工程领域中的现有研究成果，检查在车辆的技术架构中是否满足了协同驾驶场景的功能安全要求。我们将我们的方法应用在现实生活中的学术原型上，以进行合作驾驶场景，排练，并讨论我们的见解。
