To provide a data recorder and a data recording method capable of recording useful data while reducing the amount of data.SOLUTION: A data recorder according to the embodiment includes an acquisition unit, a storage unit, and a storage processing unit. The acquisition unit acquires traveling data of a vehicle at a predetermined frequency. The storage unit stores the traveling data acquired by the acquisition unit. The storage processing unit reduces the data amount of traveling data stored in the storage unit for each data item based on the data characteristics of the data item in the traveling data and the elapsed time from the time of acquisition, which allows for recording useful data while reducing the data amount.SELECTED DRAWING: Figure 2

    【課題】データ量を削減しつつ、有用なデータを記録することができるデータ記録装置およびデータ記録方法を提供すること。【解決手段】実施形態に係るデータ記録装置は、取得部と、記憶部と、記憶処理部とを備える。取得部は、車両の走行データを所定の頻度で取得する。記憶部は、取得部によって取得された走行データが記憶される。記憶処理部は、走行データにおけるデータ項目のデータ特性および取得時からの経過時間に基づき、データ項目毎に記憶部に記憶された走行データのデータ量を削減する。これにより、データ量を削減しつつ、有用なデータを記録することができる。【選択図】図2
