HIERARCHICAL MODELLING AND DIAGNOSIS FOR EMBEDDED SYSTEMS

摘要

Because of the increasing complexity of engineered systems, abstractions and hierarchies in models are receiving great attention. The behaviour of embedded systems is commonly characterised by hybrid phenomena in which each operational mode is activated by electronic units: it hence involves hardware and software components. The aim of this work is to apply a multimodelling approach on such systems for the diagnosis task. This is illustrated by an example taken from the automotive domain.
