PROBLEM TO BE SOLVED: To provide an intra-vehicle communication system for reliably transmitting all of information divided into frames to a reception side of the information from a transmission side of the information even if a key position is changed during transmission of the information via intra-vehicle communication.SOLUTION: During occurrence of a failure, when transmitting, to an audio unit 20, diagnostic information by dividing into frames, the information that has been logged (collected) immediately before the occurrence of the failure, if detecting, during transmission, in a key position, change or the like from an ON position to a START position and further to the ON position is detected, an engine ECU 16 re-transmits a division frame by returning a count value CTR (transmission frame number) of a transmission counter by a given number.SELECTED DRAWING: Figure 5

    【課題】車内通信での情報の送信中に、キーポジションの変化が発生しても、情報の送信側から情報の受信側へ、フレームに分割された情報の全てを確実に送信する車内通信システムを提供する。【解決手段】エンジンECU16は、不具合発生時に、その直前にログ(収集)していた診断情報をフレームに分割してオーディオユニット20に送信する際、送信中にキーポジションのON位置からSTART位置、さらに前記ON位置への変化等を検出すると、送信カウンタのカウント値CTR(送信フレーム番号)を所定数戻して分割フレームの再送信を行う。【選択図】図5
