Vehicle bus network system

Abstract

The invention provides a vehicle bus network system, belonging to the technical field of data switch networks and solving the problem that relatively poor expansibility of the current vehicle networks easily causes network congestion and reduces reliability. The vehicle bus network system comprises a CAN network and an LIN network; wherein, the two networks are connected by an integration gateway; the CAN network comprises a plurality of high speed CAN buses. The vehicle bus network system realizes information sharing and crossing between the CAN buses and each controller, greatly reduces the wiring harnesses through information sharing, lightens the weight of the whole vehicle, realizes core configuration function and information transfer function of the integration gateway, realizes advantage complementation of the CAN buses and the LIN buses and ensures the network has good expansibility and reliability and has low cost.

Description

technical field [0001] The invention belongs to the technical field of data switch networks, and relates to a vehicle communication system, in particular to a vehicle bus network system. Background technique [0002] With the improvement of people's requirements for automobile power, safety and comfort, automobile ECU (Electronic Control Unit, electronic control unit) and electronic control devices are also increasing, and the traditional point-to-point communication method can no longer meet the distributed real-time control of automobiles. needs. Due to the continuous increase of electronic equipment, the number of wires increases geometrically, which also makes wiring more and more difficult in the limited interior space, which limits the further expansion of interior control functions. On the other hand, each electronic control unit is not simply connected to the load equipment, but more is to exchange information with peripheral equipment and other ECUs, and issue cont...

AI Technical Summary

Problems solved by technology

Generally speaking, a CAN bus mode is suitable for a simple network, but its scalability is poor. When the system modules increase and the communication information increases, the load of the network will also continue to increase, which will bring problems such as network congestion and reduced reliability.
