Communication system, method, vehicle, storage medium, and program product

Abstract

The invention relates to a communication system and method, a vehicle, a storage medium and a program product, and relates to the technical field of vehicles, and the system comprises a plurality of domain controllers which are sequentially connected through the Ethernet to form a ring network; and a plurality of control devices, and the control devices are connected with the domain controller through a CAN network. And each domain controller is connected with at least one control device. By adopting the communication system provided by the invention, a backbone network is constructed among the plurality of domain controllers by adopting the Ethernet, the domain controllers have the functions of data forwarding, protocol conversion and the like, and the topological structure of the backbone network of the whole vehicle is simplified. Compared with the transmission rate of a traditional CAN bus, the Ethernet can achieve high-speed transmission of data, and the problems of transmission lagging, delay and the like caused by insufficient bandwidth of a traditional network are solved. In addition, a ring network formed by sequentially connecting a plurality of domain controllers has a two-way transmission path.
