Faults to Learn from: Case-Based Reasoning for Automotive Fault Cause Search

The central element of this system is the link between fault situations and their according causes based on a standard systematic. A fault-cause pair can be designated as a "case". The use of appropriate information engineering algorithms, for example case-based reasoning (CBR), allows database systems to very quickly find cases for newly occurring faults, which can be relevant for repairing the faults. This is a frequent use case, in particular for the customer service at an automobile workshop.

Another advantage is that the data basis "grows" with the experience gained by the users, a characteristic similar to an expert system. This "knowledge" expands continually during operation and usage of the system.

The utilization of a common data basis over the various areas of the automobile value chain - development, production and service - also allows a consistent handling of electronic and mechanical faults for all steps.
