In recent automotive systems, more and more applications are classified as safety related and hence are assigned an automotive safety integrity level (ASIL) according to ISO26262. Especially in the context of advanced driver assistance systems (ADAS) and automated driving, safety, reliability and availability requirements are ever increasing. In upcoming systems, a classical fail-safe design will not be sufficient in order to fulfill these requirements, and hence fail-operational systems will be essential. This holds especially true when it comes to automated driving levels 4 and 5. On the other hand, well-known approaches from the avionics industry are ill-suited for the use in automotive systems due to space, weight and power (SWAP) restrictions. This motivates the research on new, lightweight approaches for embedded fail-operational systems.
