To provide a headlight lamp control device which can illuminate a frontward direction of an own vehicle by a headlight lamp so as to be able to secure high front directional visibility of a driver of the own vehicle while avoiding dazzling of the driver of a front vehicle.SOLUTION: A headlight lamp control device 10 is configured to: perform processing for detecting an image of a preceding vehicle 201 from a front image; set the preceding vehicle indicated by the detected image as an object vehicle; acquire a length between a reference lateral line which extends in a lateral direction in the front image and an object vehicle lateral line which extends in a lateral direction in the front image and indicates a position in a longitudinal direction of the image of the object vehicle in the front image as an object longitudinal deviation; acquire a length between a reference longitudinal line which extends in a longitudinal direction in the front image and an object vehicle longitudinal line which extends in a longitudinal direction in the front image and indicates a position in a lateral direction of the image of the object vehicle in the front image as an object lateral deviation; set a target irradiation angle of a headlight lamp according to the object longitudinal deviation and the object lateral deviation; and adjust an irradiation angle of the headlight lamp to the target irradiation angle.SELECTED DRAWING: Figure 16
【課題】前方車両の運転者の眩惑を避けつつ自車両の運転者の高い前方視認性を確保できるように前照灯により自車両の前方を照らすことができる前照灯制御装置を提供する。【解決手段】前照灯制御装置10は、前方車両201の画像を前方画像から検出するための処理を行い、検出した画像が表している前方車両を対象車両として設定し、前方画像において横方向に延びる基準横ラインと、前方画像において横方向に延び、前方画像における対象車両の画像の縦方向の位置を表す対象車両横ラインと、の間の長さを対象縦偏差として取得し、前方画像において縦方向に延びる基準縦ラインと、前方画像において縦方向に延び、前方画像における対象車両の画像の横方向の位置を表す対象車両縦ラインと、の間の長さを対象横偏差として取得し、対象縦偏差及び対象横偏差に応じて前照灯の目標照射角度を設定し、目標照射角度に前照灯の照射角度を調整する。【選択図】 図16
