To enable more accurate estimation of whether a vehicle traveling ahead of the own vehicle in an adjacent lane travels with the flow of traffic or not.SOLUTION: A vehicle detection unit (101) detects a plurality of vehicles traveling in an adjacent lane, which is adjacent to a lane in which an own vehicle is traveling, based on a sensor (200) mounted on the vehicle. A speed information acquisition unit (102) acquires speed information of a preceding vehicle traveling ahead of a target vehicle traveling immediately in front of the own vehicle in the adjacent lane among the plurality of vehicles. A deceleration factor determination unit (103) determines whether there is a deceleration factor ahead of the preceding vehicle or not. A traveling state determination unit (104) determines whether the target vehicle travels with the flow of traffic or not, based on the speed information of the preceding vehicle and presence or absence of the deceleration factor.SELECTED DRAWING: Figure 1

    【課題】本開示は、隣接車線において自車両の前方を走行する車両が交通の流れに乗って走行するか否かを、より正確に推定することを可能とする。【解決手段】車両検出部(101)は、車両に搭載されるセンサ(200)に基づいて、自車両が走行する車線に隣接する隣接車線を走行する複数の車両を検出する。速度情報取得部(102)は、複数の車両のうち、隣接車線において自車両の直前を走行する対象車両より前方を走行する前方車両の速度情報を取得する。減速要因判定部(103)は、前方車両の前方に減速要因があるか否かを判定する。走行状態判定部(104)は、前方車両の速度情報、及び減速要因の有無に基づいて、対象車両が交通の流れに乗って走行するか否かを判定する。【選択図】図1
