IN-VEHICLE GATEWAY DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the number of branch connectors by fitting a branch joint circuit to a gateway device. SOLUTION: An in-vehicle gateway device relay-connects a plurality of networks. The in-vehicle gateway device has a relay processing section transmitting a signal received from one of the plurality of networks to the other network and a plurality of branch circuit sections connected to communication lines configuring communication circuitry for the networks respectively. The in-vehicle gateway device further has joint circuit sections mutually connecting the plurality of branch circuit sections while being connected to the relay processing section.
