摘要：
When data is transmitted from a first communication terminal to a second communication terminal, a communication relay device converts car identification information of a communication source of communication-source identification information included in a communication packet into a car number of a vehicle, and transmits the data to an inter-vehicle communication path. When data is transmitted from the second communication terminal to the first communication terminal, the communication relay device converts car identification information of a communication destination of communication-destination identification information included in a communication packet into a “0”-th car indicating own car, and transmits the data to an in-vehicle communication path.
