We present an approach for self-adaptation in automotive embedded systems using a hierarchical, multi-layered control approach. We model automotive systems as a set of constraints and define a hierarchy of control loops based on different criteria. Adaptations are performed at first locally on a lower layer of the architecture. If this fails due to the restricted scope of the control cycle, the next higher layer is in charge of finding a suitable adaptation. We compare different options regarding responsibility split in multi-layered control in a self-healing scenario with a setup adopted from automotive in-vehicle networks. We show that a multi-layer control approach has clear performance benefits over a central control, even though all layers work on the same set of constraints. Furthermore, we show that a responsibility split with respect to network topology is preferable over a functional split.

One goal of research activities is finding ways to manage the growing complexity of embedded systems using selfconfiguration methods. While autonomous configuration could potentially be used in safety-critical and real-time systems, the basic requirements are not yet in place. This paper will outline a concept for the real autonomous configuration of TDMA-based communication processes, which currently does not exist.The paper initially addresses the TDMA-specific framework conditions and a potential solution. The issue of the mandatory a-priori known schedule is resolved using a generic schedule, because a simple method based on "free-slot-reserved-forfurther-nodes" is not feasible. The most difficult part -the startup -was implemented through the generic schedule and an ID-based collision resolution process. To demonstrate the viability of the concept, the configuration method was implemented using a FlexRay communication system. This also satisfied the goal of eliminating the need for additional hardware and preserving the fault tolerant multimaster structure of the FlexRay system. The functionality of the concept was validated under different scenarios. The configuration times were analyzed, the results of which are also detailed here.
