POWERTRAIN DIAGNOSTICS: A MODEL-BASED APPROACH.
P A Bidian · 1999
This paper reports on work carried out in the project Vehicle Model Based Diagnosis (VMBD ), funded through the BriteEuRam III programme of the European Commission. The project aims at demonstrating the utility of model-based diagnosis for real automotive problems both in on-board and off-board situations by installing suitable systems on demonstrator vehicles. The paper presents the results obtained in three automotive drive-train subsystems which have been chosen as guiding application for the study. The paper states some of the major requirements that have been identified in these guiding applications. In particular, it is essential to solve the inherent variant problem and to reason across different 2/15 physical domains, to consider aspects of dynamically controlled technical systems and to fulfil real-time needs on-board. The evaluation provides empirical evidence for the benefit of the described approach by improving the discriminative power of automated vehicle diagnosis. 1 I...
