Layer Control

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.

AUTOSAR, a worldwide development partnership among automotive parties to establish an open and standardized software architecture for electronic control units (ECUs), has seen great success in recent years by being widely adopted in deeply embedded automotive ECUs. Increasing the security resilience of AUTOSAR based systems is a crucial step in securing safety critical automotive systems. We study AUTOSAR safety mechanisms and demonstrate how they can be used as attack vectors to degrade the vehicle safety.We show the need to harmonize the fail-safe response with the secure state of the system. And we evaluate the overlap in the properties of safety mechanisms with security objectives to highlight methods for hardening automotive systems security.
