A vision system for a vehicle includes a forward facing camera configured to be disposed at a windshield of a vehicle so as to have a forward field of view through the windshield of the vehicle. The forward facing camera is operable to capture image data for an adaptive speed control system of the vehicle. An image processor is operable to process captured image data. Responsive at least in part to processing by the image processor of captured image data, lane markers of the road along which the vehicle is traveling are detected. Responsive at least in part to processing by the image processor of captured image data, road curvature of the road along which the vehicle is traveling is determined. The speed of the vehicle may be automatically reduced the responsive to determination of a driving condition or situation.

The vision system of claim 1, wherein, responsive at least in part to processing by said image processor of captured image data, a traffic sign is recognized. 3. The vision system of claim 2, wherein said traffic sign comprises a road construction zone sign. 4. The vision system of claim 3, wherein a driver of the equipped vehicle is alerted that said road construction zone sign is recognized. 5. The vision system of claim 1, wherein, responsive at least in part to processing by said image processor of captured image data recognizing that the equipped vehicle is approaching a curve of the road along which the equipped vehicle is traveling, speed of the equipped vehicle is automatically reduced. 6. The vision system of claim 5, wherein, responsive at least in part to processing by said image processor of captured image data, a warning sign at or ahead of the curve is recognized. 7. The vision system of claim 6, wherein said warning sign comprises a speed limit appropriate for traveling around the curve and wherein, responsive at least in part to processing by said image processor of captured image data, the speed limit is determined. 8. The vision system of claim 7, wherein the speed of the equipped vehicle is automatically reduced to or below the speed limit appropriate for traveling around the curve. 9. The vision system of claim 5, wherein, responsive at least in part to processing by said image processor of captured image data, said adaptive speed control system increases the speed of the equipped vehicle to above the reduced speed when the equipped vehicle is traveling along a straighter section of road after the curve in the road has been traveled by the equipped vehicle. 10. The vision system of claim 1, wherein image data captured by said forward facing camera is processed by said image processor for a traffic sign recognition system of the equipped vehicle. 11. The vision system of claim 10, wherein sign recognition is adapted to a current geographical location of the equipped vehicle, and wherein the current geographical location of the equipped vehicle is determined by a global positioning system. 12. The vision system of claim 1, wherein, responsive at least in part to processing by said image processor of captured image data, a lane of a road along which the equipped vehicle is traveling is determined. 13. A vision system for a vehicle, said vision system comprising: a forward facing camera configured to be disposed at a windshield of a vehicle equipped with said vision system, wherein, when disposed at the windshield of the equipped vehicle, said forward facing camera has a forward field of view through the windshield of the equipped vehicle;said forward facing camera comprising an imaging array sensor and a lens;wherein said forward facing camera is operable to capture image data for an adaptive speed control system of the equipped vehicle;an image processor operable to process captured image data;wherein, responsive at least in part to processing by said image processor of captured image data, lane markers of the road along which the equipped vehicle is traveling are detected;wherein, responsive at least in part to processing by said image processor of captured image data, other vehicles exterior the equipped vehicle are detected;wherein, responsive at least in part to processing by said image processor of captured image data, road curvature of the road along which the equipped vehicle is traveling is determined;wherein, responsive at least in part to processing by said image processor of captured image data, a school bus stopping signal is detected; andwherein, responsive to the detection, at least in part by processing by said image processor of captured image data, of the school bus stopping signal, speed of the equipped vehicle is automatically reduced without the driver having to manually deactivate the adaptive speed control system of the equipped vehicle. 14. The vision system of claim 13, wherein, responsive at least in part to processing by said image processor of captured image data, a warning sign is recognized. 15. The vision system of claim 14, wherein said warning sign comprises characters and wherein, responsive at least in part to processing by said image processor of captured image data, the characters of said warning sign are determined. 16. A vision system for a vehicle, said vision system comprising: a forward facing camera configured to be disposed at a windshield of a vehicle equipped with said vision system, wherein, when disposed at the windshield of the equipped vehicle, said forward facing camera has a forward field of view through the windshield of the equipped vehicle;said forward facing camera comprising an imaging array sensor and a lens;wherein said forward facing camera is operable to capture image data for an adaptive speed control system of the equipped vehicle;an image processor operable to process captured image data;wherein, responsive at least in part to processing by said image processor of captured image data, lane markers of the road along which the equipped vehicle is traveling are detected;wherein, responsive at least in part to processing by said image processor of captured image data, road curvature of the road along which the equipped vehicle is traveling is determined;wherein the road lane along which the equipped vehicle is traveling comprises a freeway;wherein, responsive at least in part to processing by said image processor of captured image data, travel of the equipped vehicle on an exit ramp of the freeway is determined; andwherein, responsive to the determination, at least in part by processing by said image processor of captured image data, of travel of the equipped vehicle on an exit ramp of the freeway, speed of the equipped vehicle is automatically reduced without the driver having to manually deactivate the adaptive speed control system of the equipped vehicle. 17.
