Research on the Interconnection Model between Vehicular CAN Network and Internet Based on In-vehicle Gateway

This paper presents a heterogeneous network interconnection model based on a kind of translucent routing gateway and Linux virtual device to tackle with the communication issue about heterogeneous communication between various devices and Internet in the vehicular networks. In this model, an in-vehicle CAN node is regarded as a usual node in the Internet and will be assigned an IPv6 address and a MAC address as well. This mechanism will make the external terminals connect to these nodes without the perception of the in-vehicle gateway, which will implement the remote condition monitoring and fault diagnosis on a specified unit in the in-vehicle networks. Experiment result shows that this model may establish the communication between the nodes and various devices in the heterogeneous networks.
