English abstract:
Time-Triggered Architectures are being introduced in safety-critical automotive systems (X-by-wire) to cope with the growing complexity and the high safety demands. One of their merits is to provide a static operation schedule, thus largely reducing the complexity of (otherwise input-dependent) execution flow. This, however, comes for the price of increased configuration complexity: The FlexRay protocol that implements the time-triggered paradigm on the communication level requires several tens of configuration parameters. The product of their possible settings spans a space of more than 10e48 (theoretical) configurations. This does not represent a problem as long as the configuration is known and fault-free. However, in many cases ranging from debugging over conformance testing to maintenance, an identification of the configuration is desirable, but turns out extremely burdensome. This paper presents a systematic approach that facilitates parameter identification in such complex systems. Experimental results illustrate the usefulness of our approach and explore its limitations.
