To provide an on-vehicle communication device, a communication program, and a message transmission method capable of being expected to effectively use a communication band or reduce a communication delay.SOLUTION: The on-vehicle communication device includes: a classification processing unit for performing a process of classifying a message to be transmitted to another device into a plurality of groups; and a message transmission unit for selecting groups in a predetermined order and transmits a message classified into the selected groups to the other device. The on-vehicle communication device is connected to the other device via a plurality of communication lines. The message transmission unit may select a group for each communication line in a predetermined order and transmit the message. The classification processing unit classifies a message to be transmitted to the other device into a first group and a second group. The message transmission unit may alternately transmit the message classified into the first group and the message classified into the second group to the other device.SELECTED DRAWING: Figure 5 【課題】通信帯域の有効利用又は通信遅延の低減等が期待できる車載通信装置、通信プログラム及びメッセージ送信方法を提供する。【解決手段】本実施の形態に係る車載通信装置は、他の装置へ送信すべきメッセージを、複数の群に分類する処理を行う分類処理部と、所定順序で群を選択して、選択した群に分類されたメッセージを前記他の装置へ送信するメッセージ送信部とを備える。また車載通信装置は、前記他の装置と複数の通信線を介して接続され、前記メッセージ送信部は、各通信線について、所定順序で群を選択してメッセージを送信してもよい。また、前記分類処理部は、他の装置へ送信すべきメッセージを、第１群及び第２群に分類し、前記メッセージ送信部は、前記第１群に分類されたメッセージ及び前記第２群に分類されたメッセージを交互に前記他の装置へ送信してもよい。【選択図】図５
