To provide a vehicle recording device and an information recording method, capable of enhancing analysis properties of an accident cause while suppressing a storage amount of data.SOLUTION: An operation recording unit 30 includes an information acquisition part G1, a recording object setting part G2, and a recording processing part G3. The information acquisition part G1 acquires a plurality of kinds of information that can be recording objects from sensors mounted on a vehicle. The recording object setting part G2 changes the recording objects according to an operation mode of an automatic driving ECU 20. The recording processing part G3 sequentially stores data for items corresponding to the recording objects set by the recording object setting part G2 in a data storage part Mm. The items to be the recording objects are changed according to the operation mode, and thus data low in usefulness can be excluded from the recording objects in cause analysis and the like of an accident and the like. As a result, a data amount to be stored can be suppressed. In addition, the items necessary for the cause analysis can be left as the recording objects. Accordingly, analysis properties of an accident cause can be improved.SELECTED DRAWING: Figure 1
【課題】データの保存量を抑制しつつ、事故原因の解析性を高めることができる車両用記録装置及び情報記録方法を提供する。【解決手段】運行記録ユニット30は、情報取得部G1と、記録対象設定部G2と、記録処理部G3を備える。情報取得部G1は、車両に搭載されたセンサ類から記録対象となりうる複数種類の情報を取得する。記録対象設定部G2は、自動運転ECU20の運転モードに応じて記録対象を変更する。記録処理部G3は、記録対象設定部G2が設定した記録対象に該当する項目についてのデータをデータ格納部Mmに逐次保存する。運転モードに応じて記録対象とする項目が変更されるため、事故等の原因解析等に際して有用性の低いデータを記録対象から除外可能となる。その結果、保存されるデータ量を抑制できる。また、原因解析に必要な項目は記録対象として残すことができる。故に、事故原因の解析性を向上可能となる。【選択図】図1
