System and method for transferring message in ethernet based vehicle network

摘要

An Ethernet based vehicle network message transferring system is provided that includes a gateway switch that connects the Ethernet to vehicle networks having different protocols and an Ethernet switch that switches Ethernet messages between the gateway switch and vehicle devices to transfer the Ethernet messages. The Ethernet switch includes a processing module that transfers the Ethernet messages received via the gateway switch in the different vehicle networks, a vehicle network process module that switches the messages transferred from the processing module, and a lookup table in which information necessary for switching the vehicle network process module is stored. The vehicle network process module analyzes an Ethernet message transferred via the processing module in the gateway switch to identify destinations of individual messages in the Ethernet message and divides the Ethernet message including information regarding the individual message according to destinations to transmit the divided Ethernet messages to vehicle devices of destinations.

1. A vehicle network message transferring method, comprising:
receiving individual messages whose destinations are different from vehicle devices via vehicle networks, by a gateway switch; transmitting the received individual messages to an switch while one message contains the received individual messages, by the gateway switch; analyzing the received message and identifying destinations of the individual messages contained in the message, by the switch; dividing the message containing information of the individual messages based on destinations and transmitting the divided messages to the corresponding destinations, by the switch; transmitting the message by the vehicle devices connected to the switch, and receiving the message by the switch; and integrating the messages received from the vehicle devices into one message and transmitting the integrated message to the gateway switch, the switch, integrating the messages received from the vehicle devices into one message and transmitting the integrated message to the gateway switch, by the switch, wherein the switch analyzes a frame of the received message to determine whether to divide or integrate the message, and calls one of a message dividing algorithm and a message integrating algorithm to divide or integrate the message based on the algorithm.
