DRIVER ASSISTANCE SYSTEM FOR VEHICLE
First Claim
1. A driver assistance system for a vehicle, said driver assistance system comprising:
- an imaging sensor, said imaging sensor comprising a two-dimensional array of photosensor elements, said imaging sensor monitoring a scene forward of the direction of travel of a vehicle equipped with said driver assistance system;
a control;
wherein said control processes image data captured by said imaging sensor to determine the presence of an object of interest in the scene monitored by said imaging sensor;
the object of interest selected from the group consisting of (i) a headlight of another vehicle and (ii) a taillight of another vehicle;
wherein said control adjusts a vehicle headlamp of the equipped vehicle at least in part responsive to determination of the presence of the object of interest in the scene monitored by said imaging sensor;
said control receiving vehicle data via a communication bus of the equipped vehicle, said vehicle data comprising at least one of (i) vehicle speed data and (ii) vehicle trajectory data;
at least in part responsive to receiving vehicle data via said communication bus, said control inhibits adjustment of the vehicle headlamp from a first beam state to a second beam state; and
wherein said control is operable to process image data captured by said imaging sensor to determine the presence of lane markers in the scene monitored by said imaging sensor.

Abstract
A driver assistance system for a vehicle includes an imaging sensor and a control. The control processes image data captured by the imaging sensor to determine the presence of an object of interest in the scene monitored by the imaging sensor. The control adjusts a vehicle accessory and/or headlamp of the vehicle at least in part responsive to determination of the presence of the object of interest in the monitored scene. The control receives vehicle data via a communication bus of the vehicle, with the vehicle data including at least one of (i) vehicle speed data and (ii) vehicle trajectory data. At least in part responsive to receiving vehicle data, the control inhibits adjustment of the vehicle accessory from a first state to a second state. The control is operable to process captured image data to determine the presence of lane markers in the monitored scene.
