HEADLIGHT CONTROL SYSTEM

[Problem] At the time of re-irradiation of a cut-off region, both suppression of a load on a driver or an imbalance in an attention allocation and securing of safety by quick re-irradiation of the cut-off region are achieved. [0002] [Means for Solution] A headlight control system 100 has a headlight 20 including a plurality of LED light sources 23, a camera 11 and a radar 12 that detect a predetermined target object present ahead of a vehicle, and a controller 30 configured to control the headlight 20 such that, when the target object is present, of the plurality of LED light sources 23, the LED light source 23 irradiating a region where the target object is present is turned off, and such that, thereafter, when the target object is no longer present in the region, the turned-off LED light source 23 is turned on again. The controller 30 controls the headlight 20 such that, at the time of turning on the turned-off LED light source 23 again, a change rate of luminance of the LED light source 23 is changed according to a position of an irradiation region of the LED light source 23.
