"Managing change and autonomy for critical applications"

Embedded (computing) systems have become a key innovation driver for industry, thereby reaching an innovation speed even in traditional products that was unthinkable a decade ago. The flexibility of embedded software and the configurability of embedded systems networks enable continuous change after product deployment. Software updates of vehicles in the shop are becoming as common as software updates of smart phones. However, while PC or smart phone updates are often automatic and incremental, software updates of cars or other complex and safety critical systems are thoroughly lab-tested using models and prototypes under controlled conditions before they are released to the field. Despite its high cost, lab based integration is so far necessary because the possible side effects of changes in such complex systems are hard to predict and can possibly have life threatening consequences.

Funded by the German Deutsche Forschungsgemeinschaft, a new Research Group "Controlling Concurrent Change" (CCC) has been established at TU Braunschweig to research into solutions allowing continuous change even in safety critical and high availability systems without the need for expensive and time consuming lab integration tests and even in open systems. Eight scientists from Electrical Engineering and Computer Science, together with their students combine principles of contracting, self-protection, monitoring, self-optimization, with new methods of timing and safety analysis to come to a coherent approach to this engineering challenge. The solutions shall be investigated employing real uses cases in two application areas of high importance for TU Braunschweig and the region, automotive and aerospace electronics.
