To provide a time synchronization device/method capable of accurately performing time synchronization of vehicle data.SOLUTION: A vehicle data collection part 13a collects vehicle data to which time is attached and other vehicle data to which time is attached. An event detection part 13b detects the same event from the vehicle data and the other vehicle data. A time synchronization part 13c performs time synchronization between the vehicle data and the other vehicle data on the basis of the difference between the time of a first vehicle data where the same event is detected and the time of the other vehicle's data where the same event is detected.SELECTED DRAWING: Figure 1

    【課題】車両データの時刻同期を正確に行うことができる車両データの時刻同期装置及び方法を提供する。【解決手段】車両データ収集部13aは、時刻が付された車両データと、時刻が付された別の車両データとを収集する。イベント検出部13bは、車両データ及び別の車両データから同一のイベントを検出する。時刻同期部13cは、車両データと別の車両データとの時刻同期を、同一のイベントが検出された第1の車両データの時刻及び同一のイベントが検出された別の車両のデータの時刻との差に基づいて行う。【選択図】図1
