PROBLEM TO BE SOLVED: To provide a vehicle communication system capable of improving security.SOLUTION: A vehicle communication system comprises: a portable machine 3 which has a memory to store a portable machine side rolling code and a transmission section to transmit a wireless signal including the portable machine side rolling code on the basis of operation of a user; and an on-vehicle machine 4 which has a reception section to receive the wireless signal, a memory to store an on-vehicle machine side rolling code and a control section to output a signal for locking or unlocking a door on the basis of a comparison result between the portable machine side rolling code transmitted from the portable machine 3 and the on-vehicle machine side rolling code. The portable machine 3 does not update the portable machine side rolling code when an interval between unlocking operation by the user is not more than a first predetermined value t1.SELECTED DRAWING: Figure 2
【課題】セキュリティ向上を図ることができる車両通信システムを提供する。【解決手段】車両通信システムは、携帯機側ローリングコードを記憶するメモリと使用者の操作に基づいて携帯機側ローリングコードを含む無線信号を送信する送信部とを備えた携帯機３と、無線信号を受信する受信部と車載機側ローリングコードを記憶するメモリと携帯機３から送信される携帯機側ローリングコードと車載機側ローリングコードとの比較結果に基づいてドアの施解錠を行うための信号を出力する制御部とを備えた車載機４と、を有する。携帯機３は、使用者による解錠操作後における解錠操作の間隔が第１所定値ｔ１以下であれば携帯機側ローリングコードを更新しない。【選択図】図２
