The development trend of new energy power automobile wiring harness

China [CN]

According to the data, the earliest automotive wiring harness can be traced back to the early 20th century. At that time, the electrical wires of the automobile system were handmade, and there were no uniform specifications and standards. This situation not only increases manufacturing costs, but also limits the development of automotive electrical systems. To solve this problem, automobile manufacturers began to explore a more efficient and standardized form of cable organization, and automotive wiring harnesses were born.

Car wiring harness is the main body of the car circuit, no wires. Electronic control systems in modern cars are closely related to wiring harnesses. The human body is used to realize the functions of the ECU, sensors and actuators, and the ECU is equivalent to the human brain. Sensors are equivalent to sensory organs and actuators are equivalent to motor organs. Obviously, without nerves and blood vessels, the mind and various organs cannot function properly. With the continuous improvement of automobile safety, comfort and environmental protection requirements, the number of circuits and power consumption on the automobile have increased greatly, making how to arrange a large number of wire harnesses more effectively and reasonably in a limited space has become a difficult problem for automobile manufacturing. This paper briefly introduces the status quo and development trend of automotive wire harness lightweight, modularization and vehicle-borne communication technology.

With the continuous development of science and technology, the future development will be more lightweight and modular, the continuous development of automotive wiring harness and vehicle communication system will be more widely applied to the car, the development of new network communication, the car will be more intelligent, data transmission more reliable, while the requirements for wire will continue to improve.
