To obtain highly accurate submergence data.SOLUTION: A submergence data detection device includes: a vehicle data acquisition unit for acquiring vehicle data indicating the traveling state of a vehicle which includes at least acceleration data indicating an actual value of the acceleration of the vehicle traveling on a road surface and estimation data for acquiring a driving force value indicating the estimated value of driving force generated from a driving source in the vehicle and acquiring a traveling resistance value indicating the estimated value of traveling resistance applied to the vehicle; and a submergence data detection unit for detecting, on the basis of the vehicle data, submergence data indicating the submergence state of the road surface where the vehicle travels, by a detection method including a comparison of a threshold set according to the calculated value of the acceleration of the vehicle calculated from the driving force value and the traveling resistance value with the actual value of the acceleration of the vehicle, and for adjusting, according to whether or not a traveling state indicated by the vehicle data corresponds to a first state where the reliability of the calculated value of the acceleration of the vehicle is reduced, the detection method so that the detection accuracy of the submergence data in the first state is improved.SELECTED DRAWING: Figure 2

    【課題】精度の高い冠水データを得る。【解決手段】本開示の一例としての冠水データ検出装置は、少なくとも、路面を走行する車両の加速度の実値を示す加速度データと、車両の駆動源から発生する駆動力の推定値を示す駆動力値および車両に働く走行抵抗の推定値を示す走行抵抗値を取得するための推定データと、を含む、車両の走行状態を示す車両データを取得する車両データ取得部と、車両データに基づいて、駆動力値と走行抵抗値とから算出される車両の加速度の計算値に応じて設定される閾値と、車両の加速度の実値と、の比較を含む検出方法で、車両が走行する路面の冠水の状態を示す冠水データを検出し、車両データにより示される走行状態が、車両の加速度の計算値の信頼性が低下する第1の状態に該当するか否かに応じて、当該第1の状態における冠水データの検出の精度が向上するように検出方法を調整する冠水データ検出部と、を備える。【選択図】図2
