To provide a position estimation device that improves the accuracy of estimating a road on which a position estimation target vehicle is traveling.SOLUTION: A self-position estimation ECU 20 as a position estimation device estimates a position of an own vehicle EV as a position estimation target vehicle by using a PD map generated by collecting probe data from multiple vehicles. The self-position estimation ECU 20 includes: a reliability calculation unit 21 which calculates road reliability indicating whether the own vehicle EV exists for each road that has been already maintained in the PD map; and a travel road estimation unit 23 which estimates a road on which the own vehicle EV is traveling by including the road that has not been maintained in the assumption in the PD map on the basis of the calculation result of the road reliability.SELECTED DRAWING: Figure 2

    【課題】位置推定対象車両が走行している道路の推定精度を高める位置推定装置を提供する。【解決手段】位置推定装置としての自己位置推定ECU20は、複数の車両からプローブデータを収集することにより生成されたPD地図を用いて、位置推定対象車両としての自車両EVの位置を推定する。自己位置推定ECU20は、PD地図に整備済の各道路に対して、自車両EVが存在するか否かを示す道路信頼度を算出する信頼度算出部21と、道路信頼度の算出結果に基づいて、PD地図に未整備の道路を想定に含めた自車両EVが走行している道路の推定を行う走行道路推定部23を備える。【選択図】図2
