To improve accuracy in determining whether the surface of the road on which a vehicle is to be traveled, is flooded.SOLUTION: As one example, a road surface flooding determination device comprises: a travel data acquisition unit for acquiring, for each of a plurality of vehicles, a driving torque of the vehicle and actual acceleration which is practical acceleration to act on the vehicle; a determination unit for determining, for each vehicle, whether a differential between the actual acceleration and theoretical acceleration of the vehicle based on the driving torque is equal to or more than a predetermined threshold; and a judgement unit by which, in the case that a code of travel resistance of a first vehicle that is the vehicle for which it is determined that the differential is equal to or more than the predetermined threshold, based on the driving torque and the actual acceleration of the first vehicle is identical to a code of travel resistance of a second vehicle that is the vehicle which travels at the same traveling position as the first vehicle and of which the direction of travel is different, based on the driving torque and the actual acceleration of the second vehicle, it is judged that the traveling position of the first vehicle is a flooding point.SELECTED DRAWING: Figure 1

    【課題】車両が走行する路面が冠水しているか否かの判定精度を向上させることを可能とする。【解決手段】実施形態の路面冠水判定装置は、一例として、複数の車両のそれぞれについて、前記車両の駆動トルク、および前記車両に作用する実行的な加速度である実加速度を取得する走行データ取得部と、前記各車両について、前記実加速度と、前記駆動トルクに基づく前記車両の理論的な加速度と、の差分が、所定閾値以上であるか否かを判断する判断部と、前記差分が前記所定閾値以上であると判断した前記車両である第1車両の前記駆動トルクおよび前記実加速度に基づく前記第1車両の走行抵抗の符号と、前記第1車両と同じ走行位置を走行しかつ進行方向が異なる前記車両である第2車両の前記駆動トルクおよび前記実加速度に基づく前記第2車両の走行抵抗の符号と、が同じである場合、前記第1車両の走行位置を冠水地点と判定する判定部と、を備える。【選択図】図1
