- High-Speed Integration
3.1 Research and Application of In-Vehicle Ethernet
In-vehicle Ethernet is a novel local area network technology that connects in-car electronic units through Ethernet. It is primarily used in systems that require high bandwidth, such as advanced driver-assistance systems (ADAS), on-board diagnostics (OBD), and in-car infotainment systems. This technology can achieve data transfer rates of up to 100M/s and even 10G/s.
3.2 Specialized Wires and Connectors
The diversity of high-frequency signals in vehicles has led to the development of various specialized wires, such as FM/AM antenna cables, USB adapters, GPS antennas, TBOX antennas, camera cables, fakra coaxial cables, HSD video cables, and Ethernet cables. These specialized wires offer high reliability, low electromagnetic radiation, low power consumption, low latency, and synchronization capabilities, making them essential for modern automotive applications.
Trends in Automotive Networking
- Platform-Based Design
4.1 Configuration Platform
A configuration platform is built by grouping basic configurations, ensuring that the wire harnesses cover all configurations with minimal components.
4.2 Principle Platform
The vehicle’s architecture is divided into subsystems, each of which gradually transitions to a principle-based platform, allowing for efficient and scalable design and integration.
4.3 Interface Platform
By consolidating all interface information for vehicle electrical components, a comprehensive database of interface specifications is created, standardizing connections between components and wire harnesses.
4.4 Layout Platform
Wire harnesses are organized into modules based on vehicle regions, and a 3D platform-based layout architecture is established according to standardized placement principles for wire harnesses.
Principle of Segmented Layout Solutions
- Smart Manufacturing
5.1 Modular Wire Harness Design
Modular design allows the wire harness to be divided into different functional modules, each developed separately. This approach facilitates quick adaptation to various vehicle configurations, allowing for customized wire harness solutions tailored to specific vehicle models and customer needs.
5.2 Automation of Production Lines
Advancing flexible and intelligent automated production lines is a strong support for China’s “Made in China 2025” initiative and Industry 4.0. This transformation is crucial not only for enhancing product consistency and improving manufacturing efficiency but also for boosting the competitiveness of enterprises in the wire harness industry.
