PROBLEM TO BE SOLVED: To provide a communication system in which a plurality of networks are connected via a repeating device and power consumption for exchanging signals is reduced, and the repeating device utilized for the communication system.SOLUTION: In the case where control of a control target is not required, ECUs 311 to 333 are shifted to a sleep mode and save power consumption. When event frames are received from the ECUs 311 to 333, a repeating device 1 refers to a stored repeating table, transmits a wakeup frame designating ECUs 311 to 333 to be awakened to a network different from the network over which the event frame is received, and then repeats the received event frame to the network to which the wakeup frame is transmitted.

    【課題】複数のネットワークが中継装置を介して接続されて信号を送受信する消費電力の少ない通信システム及び該通信システムに利用される中継装置の提供。【解決手段】ECU311‥333は制御対象の制御が不要な場合、スリープモードに遷移し消費電力を節約する。中継装置1はECU311‥333からイベントフレームを受信した場合、記憶されている中継テーブルを参照して、ウェイクアップさせるECU311‥333を指定したウェイクアップフレームをイベントフレームを受信したネットワークと異なるネットワークに送信した後、ウェイクアップフレームを送信したネットワークに受信したイベントフレームを中継する。【選択図】図1
