To improve accuracy of route estimation of a vehicle itself higher than a conventional one.SOLUTION: A route estimation device (4), which is mounted on a vehicle itself and estimates a route of the vehicle itself, comprises: a measurement result acquisition part (402) which acquires a measurement state quantity that is a measurement result of a state quantity corresponding to lateral movement of the vehicle itself; a filter (403) which performs low-pass filter processing for a periodic measurement result of the measurement state quantity; a property setting part (404) which sets filter property, that is response characteristic in the filter, according to the measurement state quantity and a change state thereof; and an estimated route calculation part (405) which calculates an estimated route of the vehicle itself on the basis of an estimated state quantity that is an output of the filter.SELECTED DRAWING: Figure 3

    【課題】自車両の進路推定の精度を従来よりも高精度化すること。【解決手段】自車両に搭載されることで当該自車両の進路を推定するように構成された進路推定装置(4)は、自車両の横方向運動に対応する状態量の測定結果である測定状態量を取得する測定結果取得部(402)と、測定状態量の周期的な測定結果に対してローパスフィルタ処理を施すフィルタ(403)と、測定状態量またはその変化状態に応じてフィルタにおける応答特性であるフィルタ特性を設定する特性設定部(404)と、フィルタの出力である推定状態量に基づいて自車両の推定進路を算出する推定進路算出部(405)とを備える。【選択図】図3
