PROBLEM TO BE SOLVED: To provide a lighting controller of a vehicular headlight which alleviates glare to a vehicle ahead and is capable of individually irradiating a plurality of segments with light.SOLUTION: A vehicular headlight system comprises a vehicle detection part 11 that detects a position of a vehicle ahead, a light irradiation range setting part 13 that sets a light irradiation range and a non-irradiation range in accordance with the position of the vehicle ahead, a movement direction determination part 14 that determines a movement direction of the non-irradiation range, a light intensity setting part 15 that sets the light intensity of each segment, and a lighting control part 16 that generates light distribution control signals for individually lighting and extinguishing each segment and supplies the signals to vehicular headlights. The light intensity setting part 15 specifies a segment associated with the non-irradiation range out of each segment and located at an end corresponding to a movement direction of the non-irradiation range, and sets the light intensity of at least one segment adjacent to the segment located at the end on the side of the movement direction of the non-irradiation range to become lower than the light intensity of the other segments corresponding to the light irradiation range.SELECTED DRAWING: Figure 1

    【課題】前方車両へのグレアを軽減する、複数のセグメントの各々に対して個別に光照射可能な車両用前照灯の点灯制御装置を提供する。【解決手段】前方車両の位置を検出する車両検出部11と、前方車両の位置に応じて光照射範囲と非照射範囲とを設定する光照射範囲設定部13と、非照射範囲の移動方向を判定する移動方向判定部14と、各セグメントの光強度を設定する光強度設定部15と、各セグメントを個別に点灯又は消灯させるための配光制御信号を生成して車両用前照灯へ供給する点灯制御部16を含む。光強度設定部15は、各セグメントのうちで非照射範囲に対応付けられているセグメントであって非照射範囲の移動方向に対応する端のセグメントを特定し、当該端のセグメントよりも非照射範囲の移動方向の側に隣り合う少なくとも1つのセグメントの光強度を、光照射範囲に対応する他のセグメントの光強度よりも低くなるように設定する。【選択図】図1
