  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.
