Abstract

　同じ群に属するメッセージはできるだけ近い送信タイミングとし、異なる群に属するメッセージとはできるだけ離れた送信タイミングとするように送信タイミングを調整する。共通のバスに複数の端末が接続された通信ネットワークにおいて、前記バスを介して複数のＥＣＵを接続し、これらＥＣＵ間でメッセージを所定の通信間隔で送信し、該送信されたメッセージを受信する車載用の通信システムであって、ＣＡＮ通信線を介して各ＥＣＵで送受信するメッセージは、メッセージ情報の種類に応じて、第１群、第２群～第Ｎ群と複数の群に分けられており、各ＥＣＵは、送信するメッセージの群毎の送信タイミングを演算する送信タイミング演算部を備え、送信タイミング演算部は、他の電子制御ユニットから受信する第１群に属するメッセージの送信タイミングに、自ＥＣＵから送信する第１群に属するメッセージの送信タイミングを近づけるよう調整する。
