To provide an on-vehicle communication system, on-vehicle communication devices, a communication program and a communication method which can be expected to improve reliability on communication.SOLUTION: The on-vehicle communication system according to the present embodiment comprises two on-vehicle communication devices connected via two or more communication lines, and each of the on-vehicle communication devices includes a message transmission unit that transmits the same message to the other on-vehicle communication device via the two or more communication lines. In the on-vehicle communication system, the message transmission units transmit the same message with the same identification information attached thereto, and each of the on-vehicle communication devices is provided with: a message reception unit for receiving a message via the two or more communication lines; and a determination unit for determining whether or not a plurality of messages received via the two or more communication lines are the same on the basis of the identification information attached to the message received by the message reception unit.SELECTED DRAWING: Figure 1

    【課題】通信の信頼性を向上することが期待できる車載通信システム、車載通信装置、通信プログラム及び通信方法を提供する。【解決手段】本実施の形態に係る車載通信システムは、2つ以上の通信線を介して接続された2つの車載通信装置を備え、各車載通信装置は、前記2つ以上の通信線を介して同じメッセージを他の車載通信装置へ送信するメッセージ送信部を有する。車載通信システムは、前記メッセージ送信部は、同じメッセージに対して同じ識別情報を付して送信し、各車載通信装置は、前記2つ以上の通信線を介してメッセージを受信するメッセージ受信部と、前記メッセージ受信部が受信したメッセージに付された識別情報に基づいて、前記2つ以上の通信線を介して受信した複数のメッセージが同じメッセージであるか否かを判定する判定部とを有する。【選択図】図1
