Embodiment Construction

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0018] like figure 1 As shown in the figure, the vehicle bus network system includes an integrated gateway, a CAN network, a LIN network and a CAN bus diagnostic module, while the CAN network includes two power transmission CAN buses and body comfort CAN buses connected to the integrated gateway. The bus is a high-speed bus, and its communication rate is 500kbit / s. The CAN bus diagnosis module is connected with the above-mentioned power transmission CAN bus and the vehicle body comfort CAN bus, and directly diagnoses the two buses individually.

[0019] The nodes of the powertrain CAN bus include engine management module, automatic transmission control module, brake system control module, steering wheel angle sensor, four-wheel drive control mo...

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...
