A Multi-Layered Control Approach for Self-Adaptation in Automotive Embedded Systems

Abstract EN

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.
