Summary: | To provide a vehicle-mounted communication system, a vehicle-mounted relay device, a communication program, and a communication method, allowing for smooth message transmission and reception between multiple vehicle-mounted relay devices.SOLUTION: The vehicle-mounted communication system includes two vehicle-mounted relay devices, having a plurality of connection units to which communication lines are connected, for relaying transmission and reception of messages via a plurality of communication lines connected to the connection units. The two vehicle-mounted relay devices are connected via two or more communication lines. A vehicle-mounted relay device has a message transmission unit for transmitting a message to be transmitted to another vehicle-mounted relay device by selecting one communication line from the two or more communication lines in a predetermined order. The two vehicle-mounted relay devices are connected via two communication lines. The message transmission unit may alternately select one of the two communication lines to transmit a message.SELECTED DRAWING: Figure 1
【課題】複数の車載中継装置間でのメッセージ送受信の円滑化が期待できる車載通信システム、車載中継装置、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、通信線がそれぞれ接続される複数の接続部を有し、前記接続部に接続された複数の通信線を介したメッセージの送受信を中継する車載中継装置を2つ備え、2つの前記車載中継装置は、2つ以上の通信線を介して接続され、前記車載中継装置は、他の車載中継装置へ送信すべきメッセージを、前記2つ以上の通信線から1つの通信線を所定の順番で選択して送信するメッセージ送信部を有する。2つの前記車載中継装置は、2つの通信線を介して接続され、前記メッセージ送信部は、前記2つの通信線のうちの1つの通信線を交互に選択してメッセージを送信してもよい。【選択図】図1 |
