Patent Images
1. A driver assistance system suitable for use in a vehicle, said driver assistance system comprising:
- a camera disposed at and viewing forwardly through a windshield of a vehicle equipped with said driver assistance system;
wherein said camera comprises a plurality of photosensors arranged in a two dimensional array;
wherein said camera is operable to capture image data;
a control operable to process captured image data utilizing algorithmic decision-making;
wherein said algorithmic decision-making comprises use of an edge detection algorithm;
wherein said control is operable to process captured image data to detect a pedestrian present in the field of view of said camera;
wherein said pedestrian detection is based, at least in part, on a plurality of attributes selected from the group consisting of (a) size of the pedestrian, (b) shape of the pedestrian, (c) distance from the equipped vehicle to the pedestrian and (d) direction from the equipped vehicle toward the pedestrian;
wherein said control is operable to process captured image data to detect an oncoming headlight or a leading taillight of another vehicle ahead of the equipped vehicle;
a headlight of the equipped vehicle operable to illuminate at least one of generally forwardly of the equipped vehicle and generally sidewardly of the equipped vehicle;
wherein, responsive to said pedestrian detection, said control is operable to generate an alert to a driver of the equipped vehicle; and
wherein, responsive to said detection of an oncoming headlight or a leading taillight of another vehicle ahead of the equipped vehicle, a light beam of said headlight is adjusted.

Abstract
A driver assistance system for a vehicle includes a camera disposed at and viewing forwardly through a windshield of the equipped vehicle and operable to capture image data. A control operable to process captured image data utilizing algorithmic decision-making, which uses an edge detection algorithm. The control is operable to process captured image data to detect a pedestrian present in the field of view of the camera. The control is operable to process captured image data to detect an oncoming headlight or a leading taillight of another vehicle ahead of the equipped vehicle. Responsive to pedestrian detection, the control is operable to generate an alert to a driver of the equipped vehicle. Responsive to detection of an oncoming headlight or a leading taillight of another vehicle ahead of the equipped vehicle, a light beam of a headlight of the equipped vehicle is adjusted.
