TP5 - High-frequency cable sets

With sub-project 5 (TP5), the SILS focused on another future-relevant field: high-frequency (HF) cable harnesses. These are used in particular for connecting antenna systems, high-speed data lines and camera systems - in other words, wherever high data rates, low latency and electromagnetic compatibility play a key role. Especially in the context of driver assistance systems, zone architectures and networked vehicle functions, the need for high-performance, shielded signal transmission is constantly growing.

From a technical point of view, HF wiring harnesses differ significantly from classic wiring systems. They usually consist of point-to-point connections, often as coaxial cables or differentially twisted, shielded cables. Typical connector standards are, for example, FAKRA or coaxial screw and plug connections. The aim is to achieve maximum signal integrity - which places special demands on design, choice of materials and processing.

In a first step, TP5 - analogous to TP4 (HV) - examined all existing design guidelines from the low-voltage range (TP1) for their applicability in the HF context. This showed that some principles are transferable, but others can only be implemented with clear adaptation - for example due to the shielded structure, the lack of networking logic or the high influence on the electrical properties in the event of geometric changes.

A special feature of the HF sector is that many wire harnesses are already being manufactured in a highly automated process - especially by specialized assembly companies. The focus of standardization work is therefore increasingly shifting to handling, integration into process chains and digital description.

In addition to the structural design, the description of accompanying data is also a central topic in SP5. This includes, for example, digital test and product data, which is necessary for automatic documentation, traceability and quality assurance. The development of a testing strategy for RF cable harnesses is also part of the ongoing work - particularly with regard to process monitoring, tolerance limits and shielding testing.

In addition, there are thematic overlaps with TP4, for example in the area of shielded cables or in manufacturing processes with increased security requirements. Nevertheless, TP5 remains independent - with a focus on RF-specific challenges, system integration in data-driven architectures and cross-component automation capability.

TP5 makes the standard fit for the signal transmission of the future: automatable, interoperable and standardized - with the highest data quality and technical precision.
