<p>PROBLEM TO BE SOLVED: To provide a communication controller for vehicle of simple configuration in which data required to be transmitted at regular intervals, in the control of a vehicle, can be transmitted at a fixed period, and other data can be transmitted so that the transmission timing does not collide as much as possible, and delay is minimized.SOLUTION: Message generating means 33 groups a plurality of types of type transmission data for each transmission period to be transmitted, and generates a message summarized for each group. Transmission timing control means 34 transmits each message at a short period and a long period, respectively. The long period makes the transmission timing so that the multiple for the unit time is a prime. When collision of the transmission timing of a short period message and the transmission timing of a long period message is predicted, transmission collision prediction processing means 35 for delaying the transmission timing is provided.</p> |
