Considering Safety Requirements in Design Phase of Future E/E Architectures

Without meeting safety requirements in the design of electric/electronic (E/E) architectures, achieving fully-automated vehicles is infeasible. However, considering architecture-related safety requirements (e.g. redundancy for fail-operational) in the design phase is a time-consuming task that requires domain-specific knowledge. This paper tackles this challenge by proposing a novel approach under development that takes topological safety aspects into account and transforms them into an optimization problem to generate safe topologies. We aim at accelerating the architecture design process while reducing unnecessary verification efforts as well as avoiding undesired functional safety violations.
