Dynamic Reconfiguration for Real-Time Automotive Embedded Systems in Fail-Operational Context

The concept of fail-operational in safety critical systems in general and specifically in the automotive domain is often closely linked to the topic of reconfiguration. Several projects already dealt with reconfiguration in the past. However, achieving reconfiguration via hardware, software, or both is still an active area of research. The growing number of cyber-physical systems, that have been present in cars for quite some time now, require special attention to ensure proper fail-operational functionality in situations which may lead to hazardous states. The ever-increasing complexity of connected and distributed systems forces research to find novel solutions in this highly dynamical field. This paper introduces a methodological approach on how reconfiguration can be implemented. In total an innovative solution is presented which fulfills the needs of the automotive industry.
