Vehicle development is a complex process in which systems engineering and virtual development (simulation) must work closely together, both on the OEM and supplier side. To improve the quality and availability of functional data, and to further automate the creation, exchange and use of this data, both areas require digital representations (models) of components and systems. These models, in turn, require functional data as input for parameterization.
The FDX project group of the prostep ivip association defines a standard file exchange format for functional data of various components and component assemblies between OEMs and suppliers, as well as between different suppliers. As part of this objective, the project group has already published a number of recommendations for chassis components.
Einer der Schwerpunkte der Projektgruppe war im Jahr 2024 wie in den vorangegangenen Jahren die Dokumentation der Ergebnisse des FDX-Projekts. Die Arbeit und die noch im Jahr 2024 geplanten Veröffentlichungen von Empfehlungen und eines überarbeitenden Applikationsmodell für einige Chassis-Komponenten sind die zentralen Ergebnisse der Projektgruppe.
Neben der Dokumentation war und ist der Austausch mit weiteren Projektgruppen des Vereins wie auch externen wie z.B. openMDM® oder SmartSE ein wichtiger Tätigkeitsschwerpunkt. Mit dem SmartSE-Projekt findet weiterhin ein intensiver Austausch statt, mit dem Ziel, FDX in den Credible Simulation Process (CSP) zu implementieren und für das simulationsgestützte Systems Engineering nutzbar zu machen. Um den internationalen Anspruch des Standards zu dokumentieren und Wissen länderübergreifend auszutauschen, wurden Kontakte zu japanischen Standards wie Jambe geknüpft.
As in previous years, one of the project group's priorities in 2024 was to document the results of the FDX project. This work, together with the publication of recommendations and a revised application model for some chassis components, still planned for 2024, are the key deliverables of the project group.
In addition to documentation, an important focus of activity has been and continues to be the exchange of information with other project groups within the association, as well as with external groups such as openMDM® or SmartSE. There is still an intensive exchange of ideas with the SmartSE project, with the aim of implementing FDX in the CSP (Credible Simulation Process) and making it usable for simulation-based systems engineering. To document the international ambition of the standard and to share knowledge across borders, contacts have been made with Japanese standards such as Jambe.
The FDX standard leverages existing modelling standards such as openMDM and ASAM ODS, which are widely used in the automotive industry. In collaboration with the ASAM ODS Maintenance Group, the project group tested the compatibility of existing ASAM ODS-capable tools with the FDX standard. In doing so, the group found that some ASAM ODS tools that are able to process TFX files can also handle the FDX standard.
In developing the recommendations, the project group found the process to be very complex and time-consuming. Despite the creation of a technical infrastructure and intensive marketing activities, it has not yet been possible to attract more members to the project group. The difficulty for user organizations is that they cannot use the FDX standard across the board because there are still too few and too little-known tools that support it.
With the chassis component model completed, the project group will turn its attention to new components and their description in 2025. Another goal of the project group is to integrate the FDX process into the CSP as a ‘Credible Parameterization Process’ (CPP).
Another important goal is to attract additional project members and vendors to build the planned Implementor Forum.
„This year we have been able to strengthen our relationship with the ASAM ODS Maintenance Group and convince them of the benefits of the FDX standard, as both the FDX standard and their products are based on ASAM ODS. This will lower the threshold for using the FDX standard and increase its acceptance.“
„To make our expertise available, we want to speed up the delivery of new recommendations. We are hoping for support from the academic sector and input from other companies to help separate the development of the standard from the day-to-day business of vehicle development. We would also like to be involved in specific vehicle development projects to increase the use of FDX.“
