PROBLEM TO BE SOLVED: To synchronize data communication between particular nodes among a plurality of nodes about CAN communication method and system. SOLUTION: Control units such as a revolutionary ECU (electronic control unit) 10, etc., respectively having a CAN controller 30 and sensors such as a G sensor 18, a yaw rate sensor 22 are connected to one another through a CAN bus 26. The revolutionary ECU 10 needed to perform VSC control and sensors 18 to 24 are set as a node having a high priority over data transmission on the CAN bus 26. The revolutionary ECU 10 is made to transmit a trigger frame for requesting the transmission of a control parameter of VSC control to the CAN bus 26 every fixed cycle. The respective sensors 18 to 24 are made to perform A/D conversion processing of their own physical quantity whenever a trigger frame is received and to transmit data obtained as a result of the A/D conversion processing to the CAN bus 26.
