Zusammenfassung:	To provide a vehicle position estimation device that is excellent in accuracy of estimating a travel lane.SOLUTION: When a vehicle 200 is located on a road having a plurality of lanes, a vehicle position estimation device 100 calculates reliability for each lane. The reliability for each lane is not a value depending on a position in the lane. Even when position estimation accuracy based on a quantity of state of the vehicle is not good, the reliability is thus calculated for each lane on the basis of sensing information and map data, and thereby a lane on which the vehicle is located can be specified by using the reliability. Consequently, the accuracy in estimating a travel lane can be improved.SELECTED DRAWING: Figure 1 【課題】走行車線の推定精度に優れる自車位置推定装置を提供する。【解決手段】自車位置推定装置１００に従えば、複数の車線を有する道路上に自車両２００が位置する場合、信頼度を車線毎に算出する。車線毎の信頼度であるので、車線内の位置に依存する値ではない。したがって自動車の状態量に基づく位置推定精度が悪い場合でも、センシング情報および地図データに基づいて、車線毎に信頼度が算出されるので、信頼度を用いて自動車が位置する車線を特定することができる。これによって走行車線の推定精度を向上することができる。【選択図】図１
