With distributed functions taking over more and
more safety-relevant functions in modern cars,
their possible faulty behaviour has to be detected
and dangerous effects to be prevented or mitigated.
Additionally, information about the fault’s
root cause has to be provided to support repairs
in the garage. These are the central tasks of automotive
diagnosis, which is arguably a prime application
for the methods and tools developed by
the diagnosis community at large. However, our
experiences have shown that the constraints imposed
by this domain, which has a great need
for efficient and accurate diagnoses, make it very
difficult to use some of the existing methods out
of the box. The main contribution of this paper
is therefore to introduce a methodology centred
around the different stakeholders of automotive
diagnosis, in order to facilitate the employment of
model-based diagnosis approaches for the diagnosis
of vehicle functions as they are part of most
modern cars. Besides, we provide an in-depth
discussion of some of the challenges imposed by
automotive diagnosis, and relate these to existing
diagnosis methods where feasible, thereby also
further motivating our methodology.
