Robust fault detection using consistency techniques with application to an automotive engine
Monitoring of the air intake system of an automotive engine is
important to meet emission related legislative diagnosis
requirements. In this paper, the problem of fault detection in the
air intake system is stated as a constraint satisfaction problem
over continuous domains with a big number of variables and
constraints. This problem can be solved using Consistency
Techniques. Consistency techniques are shown to be particularly
efficient for checking the consistency of the Analytical Redundancy
Relations (ARRs), dealing with uncertain measurements and
parameters, and using experimental data.
