Automated Model-based FMEA of a Braking System

This paper presents work on model-based automation of failure-modes-and-effects analysis (FMEA) applied to the hydraulic part of a vehicle braking system. The FMEA task and the application problem are briefly described, and the foundations for automating the task based on a (compositional) system model are outlined. The essential parts of models of hydraulic components suitable to generate the predictions needed for the FMEA are introduced. These models are based on constraints, rather than simulation, that capture the dynamic response of the systems to an initial situation, based on one global integration step and determine deviations from nominal functionality of the device. We also present the FMEA results based on this model.
