First Claim
1. A driver assistance system for a vehicle, said driver assistance system comprising:
- a forward-viewing camera comprising an imaging sensor and a lens;
said imaging sensor comprising a plurality of photo-sensing pixels arranged in a matrix of multiple horizontal rows of photo-sensing pixels and multiple vertical columns of photo-sensing pixels;
wherein said forward-viewing camera is disposed in a windshield electronics module attached at a windshield of a vehicle equipped with said driver assistance system, said forward-viewing camera, when disposed in said windshield electronics module attached at the windshield, viewing through the windshield exteriorly of the equipped vehicle;
wherein said imaging sensor is operable to capture image data representative of a scene exterior of the equipped vehicle and in the field of view of said forward-viewing camera;
a control comprising a processor;
wherein said processor, responsive to processing of captured image data, detects lane markers within the exterior field of view of said forward-viewing camera on a road being traveled by the equipped vehicle;
wherein said processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the equipped vehicle;
wherein said processor processes captured image data via an edge detection algorithm to detect edges of vehicles present exteriorly of the equipped vehicle and within the exterior field of view of said forward-viewing camera;
wherein said processor, based on processing of captured image data, detects another vehicle that is present exterior of the equipped vehicle and determines that the detected other vehicle is in the same traffic lane as the equipped vehicle or is in an adjacent traffic lane;
wherein said processor processes captured image data to determine distance from the equipped vehicle to the detected other vehicle that is present exterior of the equipped vehicle and within the exterior field of view of said forward-viewing camera; and
wherein said processor processes captured image data for vehicle speed control.

Abstract
A driver assistance system for a vehicle includes a forward-viewing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The processor determines curvature of the road being traveled by the vehicle and detects another vehicle that is present exterior of the equipped vehicle and determines that the detected other vehicle is in the same traffic lane as the equipped vehicle or is in an adjacent traffic lane. The processor processes captured image data to determine distance from the equipped vehicle to the detected other vehicle that is present exterior of the equipped vehicle and within the exterior field of view of the forward-viewing camera. The processor processes captured image data for vehicle speed control.
