1. A vehicular adaptive driving beam headlighting system, said vehicular adaptive driving beam headlighting system comprising:

  • a camera disposed at and viewing forwardly through a windshield of a vehicle equipped with said vehicular adaptive driving beam headlighting system;

    wherein said camera comprises a plurality of CMOS photosensors arranged in a two dimensional array;

    wherein said camera is operable to capture image data;

    a control comprising an image processor;

    wherein said image processor processes image data captured by said camera at night to detect illuminated headlights present in a field of view of said camera of an oncoming vehicle that is approaching the equipped vehicle along a traffic lane to the left of a traffic lane of a road that the equipped vehicle is travelling along;

    a left-side headlamp disposed at a left-side front portion of the equipped vehicle, said left-side headlamp comprising a left-side illumination source that emits a left-side headlamp beam of light to illuminate forwardly of the equipped vehicle and sidewardly to the left of the equipped vehicle, said left-side illumination source comprising a plurality of light emitting diodes;

    wherein the left-side headlamp beam of light emitted by said left-side headlamp is adjustable;

    a right-side headlamp disposed at a right-side front portion of the equipped vehicle, said right-side headlamp comprising a right-side illumination source that emits a right-side headlamp beam of light to illuminate forwardly of the equipped vehicle and sidewardly to the right of the equipped vehicle, said right-side illumination source comprising a plurality of light emitting diodes;

    wherein the right-side headlamp beam of light emitted by said right-side headlamp is adjustable;

    wherein said image processor processes image data captured by said camera to detect an object of interest present at or near a right side edge of the road that the equipped vehicle is travelling along that is to the right of the traffic lane that the equipped vehicle is travelling along;

    wherein, responsive to detection via image processing by said image processor of captured image data of illuminated headlights of an oncoming vehicle that is travelling along the traffic lane to the left of the traffic lane that the equipped vehicle is travelling along, the left-side headlamp beam of light emitted by said left-side headlamp is adjusted to reduce glaring a driver of the oncoming vehicle;

    wherein adjustment of the left-side headlamp beam comprises selectively activating at least some individual light emitting diodes of said plurality of light emitting diodes of said left-side illumination source;

    wherein adjustment of the left-side headlamp beam responsive to detection via image processing by said image processor of captured image data of illuminated headlights of the oncoming vehicle is vertically limited so as to limit directing the headlamp beam toward the eyes of the driver of the oncoming vehicle;

    wherein adjustment of the right-side headlamp beam comprises selectively activating at least some individual light emitting diodes of said plurality of light emitting diodes of said right-side headlamp to illuminate the detected object of interest at or near the right side edge of the road;

    wherein adjustment of the left-side illumination source of said left-side headlamp to limit directing the headlamp beam toward the eyes of the driver of the oncoming vehicle is restricted at least in part to a geographical location of the equipped vehicle being at a jurisdiction that prohibits adaptively aligned lighting systems; and

    wherein adjustment of the right-side illumination source of said right-side headlamp to illuminate the detected object of interest at or near the right side edge of the road is restricted at least in part to the geographical location of the equipped vehicle being at the jurisdiction that prohibits adaptively aligned lighting systems.
