PROBLEM TO BE SOLVED: To provide a communication system, a control method and a relay method capable of preventing communication with a communication device operated by a third person through an external device.SOLUTION: In a communication system 1, communication lines 2, 3, 4 are connected to a relay device 10. A connector 20 is connected to the communication line 2, and ECUs 30, 31, 40, 41 are connected to each side of the communication lines 3, 4, respectively. An external device 50 is detachably connected to the connector 20. The relay device 10 relays the external device 50 with one of the ECUs 30, 31, 40, 41. When the control device 43 determines that the external device 50 is connected to the connector 20, a radio communication device 42 transmits, by radio, a request for signal transmission. When the control device 43 determines that the radio communication device 42 has not received a certain signal from the radio terminal 51 before a predetermined time period has passed since the transmission of the transmission request signal, the relay device 10 stops the relay of the above-mentioned communication.SELECTED DRAWING: Figure 1

    【課題】第三者が外部装置に行わせる通信装置との通信を防止することができる通信システム、制御装置及び中継方法を提供する。【解決手段】通信システム1では、通信線2,3,4が中継装置10に接続されている。コネクタ20は通信線2に接続され、ECU30,31,40,41夫々は通信線3,4の一方に接続される。外部装置50はコネクタ20に着脱可能に接続される。中継装置10は、外部装置50とECU30,31,40,41の1つとの通信を中継する。制御装置43によって、外部装置50がコネクタ20に接続されたと判定された場合、無線通信装置42は信号の送信を要求する送信要求信号を無線で送信する。送信要求信号が送信されてから所定時間が経過するまでに無線通信装置42が特定の信号を無線端末51から受信しなかったと制御装置43によって判定された場合、中継装置10は、前述した通信の中継を停止する。【選択図】図1
