To provide a system capable of realizing a light shield margin necessary enough with respect to a temperature characteristic change of a light distribution variable type head lamp unit.SOLUTION: This head lamp system comprises: a light distribution variable type head lamp unit; detection means; and a control device. The control device calculates a vehicle detection angle θ1, θ2 indicating the vehicle detection range of a surrounding vehicle FC, a margin angle θ3, θ4 set as a margin angle in which no light is applied to the surrounding vehicle when an irradiation error of the head lamp unit occurs, and a light shield indication angle (θ1+θ3, θ2+θ4) indicating a light shield range with respect to the surrounding vehicle FC. The light distribution variable type head lamp unit applies a head lamp light distribution pattern ABP (1, 2) to the outside of the light shield indication angle. The light distribution variable type head lamp includes temperature detection means. The control device changes the margin angle θ3, θ4 to a maximum irradiation margin angle in which the irradiation range of ABP (1, 2) is largest on the basis of environmental temperature detected by the temperature detection means.SELECTED DRAWING: Figure 6
【課題】配光可変型前照灯ユニットの温度特性変化に対し、必要十分な遮光マージンを実現可能なシステムの提供。【解決手段】配光可変型前照灯ユニットと、検出手段、制御装置を有し、制御装置が、周辺車両FCの車両検出範囲を示す車両検出角θ1,θ2と、前照灯ユニットによる照射誤差の発生時に前記周辺車両への照射を行わない余地角として設定されるマージン角θ3,θ4と、周辺車両FCに対する遮光範囲を示す遮光指示角(θ1+θ3、θ2+θ4)と、を算出し、配光可変型前照灯ユニットが、遮光指示角範囲の外側に前照灯配光パターンABP(1,2)を照射し、配光可変型車両用前照灯は、温度検出手段を有し、制御装置は、温度検出手段によって検出された環境温度に基づき、マージン角θ3,θ4をABP(1,2)の照射範囲を最大とする最大照射マージン角に変化させることとした。【選択図】図6
