Abstract for FISITA 2008
Title:
New Approach for Diagnostic Development and Deployment over the
Vehicle Life Cycle
Authors:
Späth, Matthias; Dr. Georg, Axel; Dr. Fritz, Martin
Abstract
The increasing complexity and networking in automotive vehicles makes
diagnostics in operation mode as well as in workshops more and more
ambitious. In recent years service diagnostic solutions could not keep pace
with the development of vehicle functions and the number of variants of
vehicles.
To revise this situation a fundamental change of mind set in diagnostics is
necessary. The new paradigm has to be that development of diagnostics is
considered equitable to development of components, systems and functions
already in early phases of product development.
The system and diagnostic knowledge of developers have to be represented
in a way that can be used in production and service. The today penetrating
standards to describe and apply diagnostic data (ODX et al.) are a first and
appropriate step into this direction. The consequent next step is the

enhancement of the existing standards by a formalized language to describe
diagnostic and functional sequences for production and service. Such a
standardized test language opens an efficient information channel for
diagnostic content from development to production and service. Diagnostic
functions for service that are already verified and validated during
development phase can be easily integrated in diagnostic testers in
production and service without effort for re-implementation. Also a re-use of
modular elements of diagnostic sequences over different vehicle models is
possible.
This state of information flow without gaps between development, production
and service can only be achieved under the prerequisites that the whole
diagnostic process is set up as an integrated process with adequate and
efficient support by software tools for each single step. Here new solutions are
required especially for development purposes. The contribution will present a
new concept (figure 1) to satisfy the mentioned requirements. The single
elements will be described in detail.
The first step of diagnostic development is diagnostic analysis of new systems
or of system variants. That is the analysis and assessment of diagnostic
capability and the identification of diagnostic gaps. The following steps are the
design of diagnostic functions and diagnostic architecture as well as the toolsupported
development of functions to be used in the diagnostic tester. The
interface between development and production or service is the creation of
sequences for the guided trouble shooting. In this context it is especially
necessary that the developer has the possibility to efficiently verify and
validate the diagnostic functions on the “target platform” (diagnostic tester)
already during function development.
The presented concept is completed by the elements authoring system,
runtime system, communication hardware and measurement devices. The
backbone of the solution are the latest state-of-the-art standards to enable
efficient generation and use of diagnostics.

Besides the presentation of the new diagnostic concept a main objective of
the suggested contribution is to motivate the discussion of the test language
idea between the attendant representatives of OEMs and automotive
suppliers.
