Functional Data Exchange (FDX)


Developing vehicles is a complex process in which the domains systems engineering and virtual development (simulation) must work closely together, both at OEMs and at suppliers. In order to improve the quality and availability of functional data and increase the level of automation for the generation, exchange and use of this data, both domains require digital representations (models) of components and systems. These models in turn require functional data as input for parameterization.
The objective of the prostep ivip Association's FDX  project group is to define a standard format for exchanging functional data for different components and component groups not only between OEMs and suppliers but also between different suppliers.

Focus and concrete results

As in previous years, one of the project group's priorities in 2023 was documenting the results of the FDX project. The work and publication of recommendations and a revised application model for several chassis components planned for 2023 are the key results achieved by the project group. It uses existing standards such as openMDM and ASAM ODS, which are widely used in the automotive industry, for FDX modeling. The project group is creating a compatibility matrix for ASAM ODS-based tools in collaboration with the ASAM ODS Maintenance group.
In addition to documentation, the exchange of information and ideas with other project groups in the association, such as openMDM, CSE, SmartSE and SysML, was and remains a key activity. There continues to be, a comprehensive exchange of information and ideas with the SmartSE project, with the aim of implementing FDX in a credible simulation process (CSP) and making it possible to utilize it for simulation-based systems engineering. In order to document the international nature of the standard and exchange knowledge at international level, contact was established to Japanese standards such Jambe.

Organizational and technical challenges

The project group found the process of creating the recommendation extremely complicated and time-consuming. Despite developing a technical infrastructure and launching comprehensive marketing activities, it was not possible to recruit new members for the project group. This leads to difficulties for user companies as it means that they are unable make broad use of the FDX standard as there are still too few and relatively unknown tools that support it.

Planning for the year 2024

In 2024, the project group intends to complete the component model for the vehicle chassis and integrate the FDX process into the CSP as a credible parameterization process (CPP). Another key objective is recruiting new project members and vendors so that the planned implementor forum can be established.

What the project coordinator says:

As both the standard and its products are based on ASAM ODS, we want to show other companies how easy it is to integrate and use the FDX standard by creating a compatibility matrix during the course of the coming year. This will lower the hurdle when it comes to using the FDX standard and increasing acceptance."

What the project manager says:

"This year, we want to move forward with providing recommendations for chassis components with the aim of making it possible to utilize our expertise. We are hoping for support from universities so that we can keep further development of the approach separate from the day-to-day business of developing vehicles. We would nevertheless also like to see it incorporated into specific vehicle development projects to promote wider use of FDX."
