Felke, T., Holland, S., and Raviram, S., "Integration of Component Design Data for Automotive Turbocharger with Vehicle Fault Model Using JA6268 Methodology," SAE Int. J. Passeng. Cars – Electron. Electr. Syst. 10(2):2017, doi:10.4271/2017-01-1623.
Suppliers and integrators are working with SAE’s HM-1 standards team to develop a mechanism to allow “Health Ready Components” to be integrated into larger systems to enable broader IVHM functionality (reference SAE JA6268). This paper will discuss how the design data provided by the supplier of a component/subsystem can be integrated into a vehicle reference model with emphasis on how each aspect of the model is transmitted to minimize ambiguity. The intent is to enhance support for the analytics, diagnostics and prognostics for the embedded component. In addition, we describe functionality being delegated to other system components and that provided by the supplier via syndicated web services.As a specific example, the paper will describe the JA6268 data submittal for a typical automotive turbocharger and other engine air system components to clarify the data modeling and integration processes. It will describe how data submittals are structured to support IVHM analytics, diagnostics and prognostics. We conclude with a discussion of how the design data aspects of these components would be certified as “SAE JA6268 Health Ready” and how the supplier can use this certification to increase the competitiveness of the component/system in the market place.
