To improve the accuracy in tracking using a time series of positions of a preceding vehicle.SOLUTION: In a vehicle position specification device comprising a controller, the controller obtains a duration period of a state in which a mutual change amount between successive positional data in time series is equal to a prescribed reference value or less, for each data group, with regard to a plurality of data groups respectively containing positional data in time series related to a preceding vehicle. Further, when a plurality of new positional data related to the preceding vehicle are generated, the controller obtains the strength of correlation between the latest positional data in time series of each data group and the plurality of new positional data, in order to add the plurality of new positional data respectively to any of the respective data groups, on the basis of the correlation strength, in order starting with data groups with relatively long duration periods.SELECTED DRAWING: Figure 6
【課題】前方車両の位置の時系列で追跡する際の精度を向上させる。【解決手段】コントローラを備える車両位置特定装置であって、コントローラは、各々が前方車両に関する時系列の位置データを含む複数のデータ群について、当該データ群毎に、時系列で前後する位置データの相互間の変化量が所定の基準値以下である状態の継続期間を求め、前方車両に関する複数の新たな位置データが発生した際に、各データ群の時系列で直近の位置データと当該複数の新たな位置データとの相関の強さを求め、相対的に継続期間が長いデータ群から順に、相関の強さに基づいて、複数の新たな位置データの各々を各データ群の何れかに追加する。【選択図】図6
