About the project


The transition to electromobility represents a major upheaval in mobility development. Automotive suppliers from Germany - especially from the federal state North Rhine-Westphalia - are playing a major role. Here, completely new, innovative vehicle concepts and solutions are being created, which in turn give rise to new system integrators through reconfigured supply chains. Digital transformation and Industry 4.0 are making this flexibility possible. At the same time, it results in a high degree of complexity in terms of development and manufacturing. A contemporary engineering approach is needed to master this complexity. Product development that conforms to standards, is distributed among several partners, and is thereby secured in terms of quality is a central key element for everyone involved in the development process. For this purpose, open standards and jointly usable tools must be created. In order to remain competitive in a global environment and to be able to bring new products to market, a number of challenges must be solved that cannot be solved by individual companies or research institutions alone. Among other things, this concerns the distributed development of products or quality assurance in the face of ever shorter development cycles.


Our solution

A modular experimental vehicle is being designed in the project, with the goal of simplifying the development, integration and verification of complex products in the field of electromobility. This experimental vehicle is designed to enable both compatibility and communication of electrical components from different manufacturers in different performance classes. The project follows the methodological approach of model-based systems engineering to cope with the increasing complexity in product development. For this purpose, digital twins are generated from real mechatronic systems of the electric drive. However, the real objects and processes are not only digitally mapped, but the concept of the digital twin creates a communication flow of data and information between real and virtual objects and processes. Based on the individual simulation models, an overall simulation can be constructed that enables virtual configuration, verification and tuning of the overall design of the powertrain and the control system with simple means.

In the previous project, a modular electromobility platform was created that also supports the validation and verification of electromobility components during the process of development of Model Based Systems Engineering. In the combined experimental vehicle and electromobility platform, the purely virtual testing of the electric drive can be expanded to include X-in-the-loop. The digital twins can be used for analysis and optimization on the one hand and for the development of new products on the other.

This will enable the design of a fully modular experimental vehicle with battery-electric and fuel cell technology-based powertrains. The fuel cell technology will not only be generated as a virtual image, but also set up and tested in the physical world and integrated into the OMEx DriveTrain platform as an alternative to battery-electric energy storage.

In addition, the system is intended to be used for training, teaching and as a demonstration platform, for example for trade fair presentations.
