At present, vehicles are becoming more and more complex, and the functions of the Internet of Vehicles are increasing in various segments, and more powerful intelligent functions are also gradually increasing. All of these advanced features rely on harnesses and controllers to function. However, facing increasing vehicle complexity and pressure to shorten product development cycles has resulted in increased cost and time pressures for automakers and system integrators. As a result, car manufacturers are innovating the existing electrical and electronic architecture. It is intended to reduce the complexity of the electronic and electrical architecture, decouple software and hardware, and provide a foundation for subsequent advanced functions.
