ETHERNET BACKBONE NETWORK SYSTEM FOR VEHICLE AND METHOD FOR CONTROLLING FAIL SAFE OF THE ETHERNET BACKBONE NETWORK SYSTEM

摘要

An Ethernet backbone network system for a vehicle and a method for controlling a fail safe of the Ethernet backbone network system enable high-speed and large-capacity data transmission between integrated control modules mounted in the vehicle, such that communication can be maintained through another alternative communication line when an error occurs in a specific communication line. The Ethernet backbone network system enables various kinds of integrated control modules mounted in the vehicle to perform large-capacity and high-speed communications, based on Ethernet communication, by connecting domain gateways of the integrated control modules through an Ethernet backbone network, and provides a fast fail-safe function so that domain gateways can perform communications through another communication line when an error occurs in a communication line between the domain gateways.

主权项

1. An Ethernet backbone network system, comprising:
a chassis gateway for communication of a chassis integrated control system; a power train gateway for communication of a power train control unit; a body gateway for communication of a body control module; a multimedia gateway for communication for a multimedia system; a first Ethernet communication link for connecting the chassis gateway and the power train gateway to communicate with each other; a second Ethernet communication link for connecting the chassis gateway and the body gateway to communicate with each other; a third Ethernet communication link for connecting the body gateway and the multimedia gateway to communicate to each other; a fourth Ethernet communication link for connecting the multimedia gateway and the power train gateway to communicate with each other; a fifth Ethernet communication link for connecting the chassis gateway and the multimedia gateway to communicate with each other; and a sixth Ethernet communication link for connecting the power train gateway and the body gateway to communicate with each other.
