PROBLEM TO BE SOLVED: To autonomously correct an error in assembling headlamps in a vehicular headlamp system that selectively irradiates a high beam.SOLUTION: Included are a light irradiation range designation unit 11 that designates a light irradiation range for vehicular headlamps, a light distribution control unit 12 that produces a light distribution control signal which instructs a light distribution pattern dependent on the light irradiation range, and outputs the light distribution control signal to the vehicular headlamps, an error detection light distribution pattern designation unit 13 that allows the light irradiation range designation unit 11 to designate a light distribution error adjustment pattern that includes a shading border extending in a lengthwise direction, a light distribution error detection unit 14 that images the light distribution pattern, which is formed by the vehicular headlamps, on the basis of the light distribution error adjustment pattern, thus obtains an image, detects the position of the shading border on the basis of the image, and obtains a light distribution error that is a displacement quantity from a reference position, and a correction value memory unit 15 that stores a correction value determined based on the light distribution error. The light irradiation range designation unit 11 uses the correction value stored in the correction value memory unit 15 to correct the light irradiation range.SELECTED DRAWING: Figure 1

    【課題】ハイビームの選択的照射を行う車両用前照灯システムにおいて前照灯の組み付け誤差を自律的に補正可能とする。【解決手段】車両用前照灯による光照射範囲を設定する光照射範囲設定部11と、光照射範囲に応じた配光パターンを指示する配光制御信号を生成して車両用前照灯へ出力する配光制御部12と、縦方向に延びた明暗境界を有する配光誤差調整用パターンを光照射範囲設定部11に設定させる誤差検出用配光パターン設定部13と、配光誤差調整パターンに基づいて車両用前照灯により形成された配光パターンを撮影して画像を得るとともに、当該画像に基づいて明暗境界の位置を検出し、基準位置からのズレ量である配光誤差を求める配光誤差検出部14と、配光誤差に基づいて定まる補正値を記憶する補正値記憶部15を含む。光照射範囲設定部11は、補正値記憶部15に記憶された補正値を用いて光照射範囲を補正する。【選択図】図1
