COMMUNICATION SYSTEM FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a communication system for a vehicle capable of controlling transferring timing to a low electric power consuming action mode from a high electric power consuming action mode as a whole of the communication system.

SOLUTION: A plurality of networks are formed by dividing a plurality of control units into more than three of a plurality of groups and connecting the control units to each other for each of the groups through a communication wire. Gate way (GW) units to relay a data are respectively provided between a plurality of the networks. The low electric power consuming action mode data is transmitted when specified time passes by transmitting the high electric power consuming action mode data to a plurality of the networks until the specified time passes even when one of the GW units receives the data showing possibility to transfer to the low electric power consuming action mode from all the connected units as a centralized control GW unit.
