Automobile lightweight is a major trend, but many people overlook a very important aspect, which is the car wiring harness. From the data, the length of the entire vehicle wiring harness of a car can move for several kilometers and weighs tens of kilograms.
You can imagine that if the length of the wiring harness can be significantly reduced, not only can the weight of the entire vehicle be reduced, driving energy consumption be reduced, but the assembly difficulty of the entire vehicle will also be greatly reduced, and the assembly speed will be greatly improved.
In summary, with the trend of electrification, intelligence, and networking in automobiles, the electronic and electrical architecture of automobiles has also undergone changes, and the wiring harnesses inside automobiles have become increasingly complex. The functional complexity of automobiles in the 1950s and today's 21st century is no longer the same. In the past, the core of automobiles may have been the power system, but now the core of automobiles has gradually shifted to various domain control of automotive electronics.
The wiring harness of automobiles is becoming increasingly complex, and the complexity of the wiring conflicts with the stability of electronic systems. How to streamline the wiring harness has become a headache in the industry.
So what are the solutions?
Tesla's domain control restructuring is a solution that no longer divides domains according to a single function, but unifies control of the same area, which can reduce duplicate wiring;
Flexible circuit board (FPC) is also a solution that uses more precise wiring harness manufacturing processes, which can significantly reduce the complexity of wiring for information transmission.
At the same time, some organizations, such as the domestic Star Flash Alliance, are also exploring whether wireless technology can replace wired technology for internal communication within the vehicle. However, considering the robustness and susceptibility to interference of wireless technology, many issues also need to be addressed.
