Abstract:
PURPOSE: A high reliability CAN(Controller Area Network) communication system using a zigbee network is provided to share situations of each electronic control unit by using a zigbee wireless network. CONSTITUTION: ECU(Electronic Control Units)(210,220,230) execute CAN communication through a connection line. When the connection line is disconnected, the ECU transmits a disconnection state information through a zigbee wireless network. An ECU management unit(200) manages one or more ECU. When the disconnection state information is received from the electronic control unit through the zigbee wireless network, the ECU management unit transmits the disconnection state information to one or more other ECU.
