PROBLEM TO BE SOLVED: To solve the problem in which providing a technique making it possible to estimate a state of a travelling road with higher accuracy has been desired.SOLUTION: A travelling road information estimation device is provided that comprises: an acquisition unit that acquires a detection result including at least any one of a distance between the object and the sensor, and reception intensity in the sensor of a reflection wave from the object, and a speed of the object, on the basis of a beat signal to be obtained from a reception wave reflected by an object existing in a travelling road and received by a sensor; a tracking unit that, on the basis of the detection result and tracking data on each of a plurality of objects, associates the detection result with any of the plurality of objects to update the past detection result of each of the plurality of objects or the tracking data thereon; and a determination unit that determines a states of the travelling road on the basis of post-updated tracking data or the past detection result after updated.SELECTED DRAWING: Figure 1

    【課題】走行路の状態をより高精度に推定することを可能とする技術が提供されることが望まれる。【解決手段】走行路に存在する物体によって反射されてセンサによって受信された受信波から得られるビート信号に基づいて、前記物体と前記センサとの距離および前記物体からの反射波の前記センサにおける受信強度の少なくともいずれか一方と前記物体の速度とを含む検知結果を得る取得部と、前記検知結果と複数の物体それぞれの追跡データとに基づいて、前記検知結果と前記複数の物体のいずれかとの対応付けを行って前記複数の物体それぞれの過去の検知結果または前記追跡データを更新する追跡部と、更新後の前記追跡データまたは更新後の前記過去の検知結果に基づいて、前記走行路の状態を判定する判定部と、を備える、走行路情報推定装置が提供される。【選択図】図1
