Abstract:

Considering safety requirements while developing electrical and electronic （E/E） architectures is a prerequisite for the realization of future technologies such as autonomous driving. Following the ISO 26262 standard， safety analyses have to be conducted in the early phase of the development lifecycle in order to detect design flaws and take actions to improve the design. This paper presents a model-based approach for addressing safety requirements conforming to ISO 26262 during the design phase of automotive E/E architectures. Based on the requirements， a set of safety-related constraints is extracted， which can be used in an integer linear programming （ILP） model to optimize E/E architectures.

Key words:functional safety;E/E architecture;optimization;model-based development
