Fail-Safe Data Management in Self-Healing Automotive Systems

Software-based functions are getting more and more important in networked embedded systems, like vehicles, aircrafts or plants. Especially, safety-critical functionalities demand a high degree of dependability. Self-healing is promising approach to increase the reliability of systems. In case of an hardware fault, functions can be dynamically reallocated onto other devices, thus preventing loss of function. However, the faulty device will cause loss of data unless there is redundant data storage. In this paper we outline concepts for the data management in self-healing automotive systems which enable the recovery of software-based functionalities.
