Driven by the automotive megatrends of connectivity, automation, and shared mobility, the electric and electronic architecture (E/E architecture) of future cars is undergoing a paradigm shift from hardware towards software-based approaches, leading to a service-oriented architecture (SOA). Therefore, the increasing use of software will play a crucial role in the future automotive industry. New possibilities of increasing connectivity and updates over the air enhance the advantages and need of a SOA. At the same time, new opportunities for the after-sales market can be derived, as functions can be purchased on a modular basis. Introducing upgrades within the vehicle’s life cycle leads to the difficulty that not the entire configuration of the E/E architecture is known during the development process, which leads to one of the biggest challenges in terms of safety.

    After investigating a general safety concept for an open adaptive system, we transferred the approach to the automotive context and demonstrated its applicability. At its core, the concept is based on safety certificates that are conditionally specified by the current system configuration. Considering ISO 26262 and the existing safety mechanisms of static E/E architecture, we derived the certificates’ content. During the continuous evolution, the overall system is certified by the sum of the safety certificates of its subsystems. Thus, this concept enables a shift of the safety analysis from the development phase to the life cycle.
