To provide appropriate antiglare performance.SOLUTION: An illumination ECU sets a reference range (upper limit luminance Lmax and lower limit luminance Lmin) in response to whether or not an object detected from a camera image exists in a gaze area A (S17 to S19). In this case, the gaze area A is set based on a road surface vanishing point X of an own vehicle line. When the object exists in the gaze area A, the upper limit luminance Lmax and the lower limit luminance Lmin are set to be larger than a case in which the object exists outside the gaze area A. When a detection luminance Lx of the object is beyond the upper limit luminance Lmax, the illumination ECU reduces an LED target output P*. When the detection luminance Lx of the object is below the lower limit luminance Lmin by darkening control, the illumination ECU increases the LED target output P*.SELECTED DRAWING: Figure 2

    【課題】 適正な防眩性能が得られるようにする。【解決手段】 照明ECUは、カメラ画像から検知した物体が注視エリアA内に存在するか否かに応じて、基準範囲(上限輝度Lmax,下限輝度Lmin)を設定する(S17〜S19)。この場合、注視エリアAは、自車線の路面消失点Xに基づいて設定される。上限輝度Lmaxおよび下限輝度Lminは、物体が注視エリアA内に存在する場合には、物体が注視エリアA外に存在する場合に比べて、大きな値に設定される。照明ECUは、物体の検知輝度Lxが上限輝度Lmaxを上回る場合には、LED目標出力P*を減少させる。照明ECUは、減光制御によって物体の検知輝度Lxが下限輝度Lminを下回る場合には、LED目標出力P*を増加させる。【選択図】 図2
