To improve a classification accuracy of vehicle data.SOLUTION: A vehicle data classification method includes: repeatedly performing processing of selecting vehicle data for a second time t2 from time series data while shifting the time by a third time t3 and overlapping a part of a previous selection range Am-1 and a part of a current selection range Am-1 so as to determine a vehicle condition indicated by the vehicle data included in each selection range Am; and selecting a detection time Tn of the vehicle data to be classified, selecting all selection ranges Am including the vehicle data of the selected detection time Tn, and specifying the most included vehicle condition from among one or more vehicle conditions indicated by the vehicle data included in the selected selection range Am so as to classify all types of vehicle data detected at the selected detection time Tn as data of the specified vehicle condition.SELECTED DRAWING: Figure 5

    【課題】車両データの分類精度を向上させる。【解決手段】時系列データから第2時間t2分の車両データを選択する処理を、第3時間t3分ずらしつつ、且つ、前回の選択範囲Am−1の一部と今回の選択範囲Amの一部を重ねながら繰り返し行い、個々の選択範囲Amに含まれる車両データが示す車両状態を判定し、分類すべき車両データの検出時期Tnを選択し、選択された検出時期Tnの車両データを含む全ての選択範囲Amを選択し、選択された選択範囲Amに含まれる車両データが示す1以上の車両状態の中から最も多く含まれる車両状態を特定し、選択された検出時期Tnに検出された全ての種類の車両データを特定された車両状態のデータとして分類する。【選択図】図5
