Problems solved by technology

The existing communication network for electric smart vehicles has poor scalability. Once the communication network is configured, when a new unit controller is added inside the car, it is difficult to connect the new unit controller to the previously established communication network. Reconfiguring the network will bring a lot of work

Abstract

The invention relates to an electric smart automobile communication network system based on extensible annular Ethernet. The system includes an inner loop network which comprises a plurality of controllers and corresponding inner loop Ethernet switches, wherein the controllers are connected through corresponding Ethernet port of the inner loop Ethernet switches in a loop so as to form an intelligent decision and control unit used for performing collection and processing on information data of an electric smart automobile; a plurality of peripheral networks taking the inner loop network as the first node and connecting a plurality of intelligent sensors or intelligent actuators of the electric intelligent automobile successively through corresponding Ethernet ports of peripheral Ethernet switches for forming a peripheral linear network or annular network, wherein each peripheral Ethernet switch is provided with an extensible Ethernet port used for connecting with an extension network. Compared with the prior art, the system provided by the invention has advantages of low communication network cost, high stability, good extensibility and the like.

Description

technical field [0001] The invention relates to an electric intelligent vehicle communication network system, in particular to an electric intelligent vehicle communication network system based on an expandable ring Ethernet. Background technique [0002] With the rapid development of automobile intelligence, the number of unit controllers inside the vehicle has increased dramatically, and the complexity of computing data has also further increased, which puts forward higher requirements for the communication method and topology network structure between the various controllers of the vehicle. The existing communication network for electric smart vehicles has poor scalability. Once the communication network is configured, when a new unit controller is added inside the car, it is difficult to connect the new unit controller to the previously established communication network. Reconfiguring the network will bring a lot of work. Contents of the invention [0003] The object ...
