The automotive electronics architecture of the future is changing rapidly. Safety features and autonomous driving functions require better computing power and higher bandwidth communication capabilities. In order to make the car have better connectivity and infotainment functions, the car will be transformed into a distributed IT system, which can communicate with the cloud to remotely update software, and update digital map information and traffic conditions in real time. Future automotive electronic and electrical architecture, which needs to have the ability to interact between different components and different functional modules, and be able to manage and control an increasing number of functions and complex software algorithms. In addition, the framework should be scalable to handle increasing demands and expectations on vehicle functionality over time. OTA should also be one of the necessary functions of the architecture. The updateability and upgradeability of the automotive electronic architecture enables the OEM to control the upgrade process of the car after the car is sold. The separation of software and hardware makes the software functions of the car independent of the hardware, which greatly improves the scalability of system functions and the convenience of updates.
