With the in-depth integration of functional domains, functional domains are gradually upgraded to more general computing platforms, from functional domains to location domains (such as central domain, left domain, and right domain). Zonal Control Unit ZCU is a local perception, data processing, control and execution unit in the vehicle computing system. It is responsible for connecting sensors, actuators, and ECUs in a certain area of the vehicle, and is responsible for the preliminary calculation and processing of sensor data in this location domain, and is also responsible for network protocol conversion in this area. The location domain realizes the nearby arrangement of wiring harnesses, reduces costs, reduces communication interfaces, and makes it easier to realize automatic assembly of wiring harnesses to improve efficiency. Sensors, actuators, etc. are connected to nearby regional controllers, which can better realize hardware expansion and make the structure management of regional controllers easier. Regional access to central computing ensures the stability of the vehicle architecture and the scalability of functions. Newly added external components can be accessed based on regional gateways. The pluggable design of hardware supports the continuous improvement of computing power, and sufficient computing power supports application software. Iteratively upgrade on the central computing platform.
