Digital, virtual development is the norm in the automotive industry. Ever better and more detailed models are being used to predict and validate vehicle performance. However, the quality of this work depends to a large extent on the quality of the available parameters. When it comes to geometric data, standards have already been established, but there is still a great need for standards where functional models are concerned. The specification, generation and use of such parameters usually take place at different companies (OEMs, suppliers).

The aim is therefore to define a standard within the framework of the FDX project which can be used to exchange functional data (characteristic values, characteristic curves) in a uniform and machine-readable format.

The standard is based on ASAM-ATFX, adds elements from openMDM and enhances the data model by adding necessary aspects and thus defining it in greater detail. This makes it possible to ensure the required level of reliability, obligation, consistency and process reliability when providing functional data.
