To provide a headlight lamp control device which can optimize radiation of a headlight lamp in a vertical direction.SOLUTION: A headlight lamp control device 10, which controls radiation of a headlight lamp 30 which radiates the front of an own vehicle M, comprises: a height acquisition part 11 which acquires height information of a front vehicle MA which travels the front of the own vehicle M; a sinking amount detection part 12 which detects a sinking amount of the own vehicle M in a vertical direction; an error calculation part 13 which calculates an inclination error, which is an error of inclination in a cross direction of the own vehicle M, on the basis of the sinking amount detected by the sinking amount detection part 12; and a range control part 15 which controls an irradiation range of light of the headlight lamp 30 in a vertical direction on the basis of height information of the front vehicle MA acquired by the height acquisition part 11 and the inclination error calculated by the error calculation part 13.SELECTED DRAWING: Figure 2
【課題】本発明は、前照灯の上下方向の照射を適正なものとすることができる前照灯制御装置を提供することにある。【解決手段】自車両Mの前方を照射する前照灯30の照射を制御する前照灯制御装置10であって、自車両Mの前方を走行する前方車両MAの高さ情報を取得する高さ取得部11と、自車両Mの上下方向の沈み込み量を検出する沈み込み量検出部12と、沈み込み量検出部12で検出された沈み込み量に基づいて、自車両Mの前後方向の傾きの誤差である傾き誤差を算出する誤差算出部13と、高さ取得部11により取得された前方車両MAの高さ情報及び誤差算出部13で算出された傾き誤差に基づいて、前照灯30の上下方向の光の照射範囲を制御する範囲制御部15とを備える。【選択図】 図2
