The system interconnection within the various domains CAN still use the CAN and FlexRay communication buses that are now quite common. Communication between different domains requires that ethernet with higher transmission performance is used as a backbone network to undertake information exchange tasks. In each functional domain, domain controllers are absolutely central, requiring powerful processing power and ultra-high real-time performance, as well as a large number of communication peripherals.
