Abstract

A vehicular adaptive driving beam headlighting system includes a camera disposed at and viewing forwardly through a windshield of a vehicle. A control includes an image processor that processes image data captured by the camera at night to detect headlights present in a field of view of the 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 is disposed at a left-side front portion of the equipped vehicle and a right-side headlamp is disposed at a right-side front portion of the equipped vehicle. Responsive to detection of headlights of an oncoming vehicle, the left-side headlamp beam of light is adjusted to reduce glaring a driver of the oncoming vehicle.
