PURPOSE: A CAN(Controller Area Network) is provided to transmit a signal included in a CAN communication message by constructing a message ID(Identification) regarding a necessary transmission period. CONSTITUTION: Transmission rankings for a plurality of messages in a node are determined regarding the priority of an ID. Each ID of the messages is determined by considering the importance of a signal and a necessary transmission period. The priority of the messages in the node is high when the transmission period is short. The priority of the message in the node is high when the importance of the signal is high. The transmission ranking of the messages in the node is high when the number is less. [Reference numerals] (AA) Classification; (BB) Signal priority; (CC) Transmission cycle |
