Safety-relevant development by adaptation of standardized safetybconcepts in AUTOSAR 4.0

International audienceThe ECUs in a vehicle network need a reliable and safe interconnection between each other. This is especially valid for new functionality, e.g. for systems like drive-by-wire. Current published standards like the software standard AUTOSAR or the functional safety standard ISO26262 ease and enable the development of safe interconnections. Furthermore, to enable fast innovation cycles, an incremental adaptation and development process is necessary. The combination of the development of new functionality, the introduction of new standards, and the reuse of existing solutions is a big challenge for the development of the vehicle E/E network. This paper presents approaches to handle these challenges. For that, a classification of communication related errors is introduced. Solutions are given with the help of error detection mechanisms and means to adapt the safe communication concepts from AUTOSAR release 4.0 to an existing solution based on a former release
