In the traditional automotive supply chain, different ECUs come from different suppliers, and different hardware has different embedded software and underlying code. The vehicle software is actually a mixture of many independent and incompatible software, resulting in the lack of compatibility of the entire system. and scalability. To make any function changes, the car factory needs to negotiate with many different suppliers to coordinate the development of software and hardware. Every time a new function is added, it needs to add an ECU and communication system, which takes a long time and the process is cumbersome. And because each ECU is bound to a specific function, it is impossible to realize complex functions across multiple ECU sensors, and it is also impossible to keep the car software continuously updated through OTA (Over the Air).
Distributed electrical and electronic architectures lead to communication bandwidth bottlenecks. The functions of intelligent networked vehicles are becoming more and more complex, the number of vehicle sensors is increasing, and the resulting real-time requirements for data transmission and processing are increasing. The amount of communication data in the internal network of automobiles is increasing exponentially. It has been unable to provide high-bandwidth communication capabilities, nor can it meet the real-time requirements of data transmission and processing.
