Our second virtual trend outlook event will take place on September 27, 2023, where you will have the next opportunity to gain an insight into three trend topics in the wiring harness industry. For this event, too, we will select interesting topics whose technical possibilities and potential applications in the wiring harness sector will be presented by renowned experts. The focus is on approaches that are at an early technological stage (TRL 3-4). The agenda with the topics and speakers is currently being finalized and will be continuously updated.
Under the title Safe Reconfiguration of Automotive TSN Networks The Institute for Data Technology and Communication Networks (IDA) of the Technical University of Braunschweig present an innovative approach for dynamic resource management in real-time networks. The increasing demands on on-board networks resulting from new driver assistance systems and the sensors required for them lead to large amounts of data and high data dynamics. Coping with the dynamics presents new challenges for secure reconfiguration. A centralized network management approach represents a promising solution to this challenge. The working group led by Prof. Dr.-Ing. Rolf Ernst deals with the architecture and design of embedded and cyber-physical systems and has already been able to demonstrate its expertise in the field of data on-board networks in research projects such as ERIKA (Eelectromobility with Redundant Iintelligent KcommunicationsAarchitecture), in which the TU Chemnitz, BMW and Porsche were also involved.
The topic Wiring harness 4.0 – The implementation of a standardized digital twin will be presented by Dr. Alexander Salinas from the company Draxlmaier and deals with the implementation of a standardized digital twin (administration shell) in the value chain of the wiring harness. The wiring harness industry, and in particular the production and assembly of the wiring harness, struggles with proprietary data standards, manual activities in production and assembly, and a volume of information that is difficult to manage (product data, quality data, etc.). Automating this product is challenging because the wiring harness is produced in batch size 1 according to the current state of the art and the know-how is provided by various value creation partners.
The content of the presentation will refer to previous project results and approaches (e.g. linking, versioning, synchronization between different administration shells) that are to be implemented in the further course of the project. The aim is to demonstrate the possible potential through the implementation of a standardized digital twin.
The connection and contact technology of detachable connections, the connector technology, is of particular importance in the on-board network. Typical failures, such as those caused by frictional corrosion or chemical corrosion, have short warning times and can still lead to the failure of important systems. Integrated monitoring of the current connection quality using integrated, miniaturized electronic sensor systems could help. In the presentation smart connectors Dr. Frank Ansorge from Fraunhofer EMFT Applications for intelligent connectors. In the future, new active connectors can have sensor and diagnostic functions for the connected devices (e.g. recording energy consumption, faulty states, etc.). The presentation will examine in detail the requirements for various sensors and sensor technologies. The focus is on the consistent availability of process information, status diagnostics and energy management, as an important part of the (on-board network) connection technology.
documentation of the event
The presentations during the event covered a wide range of topics in the field of wiring harnesses. Various technologies, including real-time data networks, digital twins and intelligent connectors, were presented. However, there are certainly interested parties who were unable to attend the event live. Therefore, we offer the presented slides for download and also provide the recordings of the presentations. Our special thanks go to the speakers for their captivating presentations and their agreement to make both the slides and the recordings available. We are happy to answer any questions you may have and to support you in further discussions.
