<p>PROBLEM TO BE SOLVED: To increase the number of source ID to be attached to a message, in a multiplex communication system including a plurality of communication nodes.SOLUTION: One of a plurality of communication nodes loaded on a vehicle and connected to a communication bus includes: a control unit for generating a communication node identifier of a transmission source and a message having an attached communication node identifier of a transmission destination; and a transmitter unit for transmitting the message generated by the control unit. The control unit, when attaching the communication node identifier of the transmission source to the message, attaches the identifier of the self-communication node to a first region in which a region for attaching the communication node identifier of the transmission source is combined with an additional information region not in operation.</p> |
