PROBLEM TO BE SOLVED: To detect and cope with illegal data transmission even in the case of a network configuration in which inter-device communication is other communication than broadcast communication.SOLUTION: A transmission ECU 12 includes: a transmitter unit 30 which, on receiving transmission data transmitted from the outside, transmits the transmission data to data notification equipment 14 which notifies a transmission ECU 12 and reception ECUs 16A, 16B of the received transmission data; and a receiver unit 32 which receives the transmission data received and notified from the data notification equipment 14. If the received transmission data received by the receiver unit 32 is different from the transmission data which is transmitted to the data notification equipment 14 immediately before, the transmitter unit 30 retransmits, to the data notification equipment 14, the transmission data transmitted to the data notification equipment 14 immediately before.SELECTED DRAWING: Figure 2

    【課題】装置間の通信がブロードキャスト通信以外の通信であるネットワーク構成の場合であっても、データの不正送信を検知して対処する。【解決手段】送信ECU12は、外部から送信された送信データを受信した場合に前記受信された送信データを送信ECU12及び受信ECU16A、16Bに通知するデータ通知器14に対して、送信データを送信する送信部30と、データ通知器14から通知された、前記受信された送信データを受信する受信部32と、を含み、送信部30は、受信部32により受信された前記受信された送信データが、直前にデータ通知器14に対して送信した送信データと異なる場合、該直前にデータ通知器14に対して送信した送信データをデータ通知器14に再送信する。【選択図】図2
