Model-Based Tools for the Integration of Design and Diagnosis into a Common Process - A Project Report

Abstract

The growing importance of on-board diagnosis for automobiles demands for a close integration of diagnostic tasks in the entire design process. This report describes work carried out to date within the European project 'Integrated Design Process for onboard Diagnosis' (IDD). It presents an analysis of the current design process and the model of a new process which allows for a better integration of diagnosis related tasks, such as diagnosability analysis, failure-modes-and-effects analysis (FMEA), on-board diagnosis design, in the overall design process of mechatronic subsystems. We then discuss in what way model-based technology can provide tools to support the actual integration and, in particular, present an approach to model-based diagnosability analysis.
