PROBLEM TO BE SOLVED: To provide a communication controller for properly predicting the time when a next specific message is received without being affected by transmission path delay, and also to provide a communication system and a communication control method.SOLUTION: A timing predicting part 31 predicts the time when the next message m is received, based on the reception interval between the two messages m which are determined to be the same kind of messages m transmitted from the same node 10 and also determined to have a bus idle tthat shows a non-communication state immediately before the reception of the message m. When the message m is received immediately after the bus idle t, the transmission of the message m is not delayed by another message ma to be transmitted from another node. Thus, the transmission interval of the transmission source of the message m coincides with the reception interval on a reception side. Consequently, the time when the next message m is received is properly predicted without being affected by the transmission path delay. |
