Provided are an onboard communication device, a communication program, and a message transmission method that can be expected to enable effective utilization of communication bandwidth, reduce communication delay, etc. The onboard communication device according to the present embodiment comprises a sorting processing unit for executing a process of sorting messages to be transmitted to another device into a plurality of groups; and a message transmission unit for selecting a group by using a prescribed order and transmitting messages sorted into the selected group to the other device. The onboard communication device is connected to the other device via a plurality of communication lines, and the message transmission unit may, for each communication line, select a group and transmit messages by using the prescribed order. In addition, the sorting processing unit may sort messages to be transmitted to the other device into a first group and a second group, and the message transmission unit may alternately transmit, to the other device, messages sorted into the first group and messages sorted into the second group.

    提供一种能够期待通信带域的有效利用或通信延迟的减少等的车载通信装置、通信程序及消息发送方法。本实施方式的车载通信装置具备:分类处理部,进行将应向其他的装置发送的消息分类为多个组的处理;及消息发送部,按照规定顺序选择组,将被分类为所选择的组的消息向所述其他的装置发送。而且,也可以是,车载通信装置经由多个通信线与所述其他的装置连接,所述消息发送部对于各通信线按照规定顺序选择组而发送消息。而且,也可以是,所述分类处理部将应向其他的装置发送的消息分类为第一组及第二组,所述消息发送部将被分类为所述第一组的消息及被分类为所述第二组的消息交替地向所述其他的装置发送。
