To provide drive assistance useful for a driver by estimating a position of a lane marking of a cruising lane even in such an environment that it is hard for the driver to visually recognize the lane marking.SOLUTION: A processor acquires information on a position of a real lane marking 320 which is based on at least an image captured by a camera 401 provided in a self-vehicle and information on a position of a stationary object 330 which is provided along a cruising lane of the self-vehicle and is based on detection by one or more sensors 403, 405 provided in the self-vehicle and having a different detection method from that of the camera 401, calculates an interval D between the real lane marking 320 and the stationary object 330 on the basis of the information on the position of the real lane marking 320 and the information on the position of the stationary object 330, estimates a position of a virtual lane marking EL on the basis of the calculated interval D and the position of the stationary object detected by the sensors 403, 405 and then displays a line image 200 along the virtual lane marking EL.SELECTED DRAWING: Figure 1

    【課題】走行レーンの区画線が視認しづらい環境でも区画線の位置を推定し、運転者に有益な運転支援を提供する。【解決手段】プロセッサは、自車両に設けられたカメラ401により撮像された画像に少なくとも基づく実区画線320の位置に関する情報と、自車両に設けられたカメラ401と異なる検出方法を有する1つ又はそれ以上のセンサ403,405による検出に基づく自車両の走行レーンに沿って設けられる静止物標330の位置に関する情報と、を取得し、実区画線320の位置に関する情報と、静止物標330の位置に関する情報と、から実区画線320と静止物標330との間隔Dを算出し、算出した間隔Dと、センサ403,405で検出される静止物標の位置と、から仮想区画線ELの位置を推定し、この仮想区画線ELに沿った線画像200を表示する。【選択図】 図1
