車両1内の各ECUは、OTA機能によって配信された更新版プログラムを用いてそれぞれのソフトウェアを更新する。収集機能部131は、コンフィグデータ1382を更新する。診断管理部1381は、本ステップとは別に、定期的にコンフィグデータ1382を更新する。
収集機能部131は、収集したログを収集サーバ部211に送信する(S709)。ログ分析部215は、収集したログを分析し、分析結果を蓄積する(S710)。
本実施形態1に係るECU13は、各ECUが備えるプログラムの更新状態を記述したコンフィグデータ1382を収集し、コンフィグデータ1382が記述している各更新状態に対応する更新版プログラムをデータセンタ2から取得してその更新版プログラムによってプログラムを更新する。その他のECUも同様のデータセンタ2から受け取った更新版プログラムによって演算プログラムを更新する。車両1が搭載する全ECUのソフトウェアバージョンやROM空き容量などのソフトウェア状態を、車両1とデータセンタ2それぞれにおいて一致させて管理することによって、適切なプログラム更新を実現している。さらに、全ECUのソフトウェア状態をECU13が統括的に管理することにより、各ECUの演算プログラムとECU13の収集プログラム1371を連携して生成することができる。
実施形態1において、各ECUの演算プログラムと収集プログラム1371を連携して更新することを説明した。これらは必ずしも同時に更新する必要はなく、以下のいずれかを更新してもよい。
(更新例2)収集プログラム1371とECU13上の演算プログラム
(更新例3)収集プログラム1371
(更新例4)収集プログラム1371といずれか2以上(車両1上のECUのうち一部)のECU上の演算プログラム
本発明は上記実施形態に限定されるものではなく、様々な変形例が含まれる。例えば、上記実施形態は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施形態の構成の一部を他の実施形態の構成に置き換えることが可能であり、また、ある実施形態の構成に他の実施形態の構成を加えることも可能である。また、各実施形態の構成の一部について、他の構成の追加・削除・置換をすることが可能である。
