Driver assistance system for a vehicle
DCFirst Claim
1. A driver assistance system for a vehicle, said driver assistance system comprising:
- an imager comprising a CMOS photosensor array of photosensor elements;
wherein said imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle equipped with said driver assistance system, and wherein said imager has a forward field of view to the exterior of the equipped vehicle through the windshield of the equipped vehicle;
wherein said CMOS photosensor array is operable to capture image data;
a control comprising an image processor;
wherein said driver assistance system identifies objects in said forward field of view of said imager via processing of captured image data by said image processor;
wherein, at least in part responsive to processing of captured image data by said image processor, a determination is made that the equipped vehicle is being operated in an urban environment; and
wherein, responsive to said determination that the equipped vehicle is being operated in an urban environment, operation of a driver assistance function of the equipped vehicle is inhibited.

Abstract
A driver assistance system for a vehicle includes an imager and a control having an image processor. The imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle and has a forward field of view to the exterior of the vehicle through the vehicle windshield. The driver assistance system identifies objects in the forward field of view of the imager via processing of captured image data by the image processor. At least in part responsive to processing of captured image data by the image processor, a determination is made that the vehicle is being operated in an urban environment. Responsive to the determination that the vehicle is being operated in an urban environment, operation of a driver assistance function of the vehicle is inhibited.

14. A driver assistance system for a vehicle, said driver assistance system comprising:
-
an imager comprising a CMOS photosensor array of photosensor elements; wherein said imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle equipped with said driver assistance system, and wherein said imager has a forward field of view to the exterior of the equipped vehicle through the windshield of the equipped vehicle; wherein said CMOS photosensor array is operable to capture image data; a control comprising an image processor; wherein said driver assistance system controls switching a headlamp of the equipped vehicle from a low-beam state to a high-beam state via processing of captured image data by said image processor; wherein, at least in part responsive to processing of captured image data by said image processor, a determination is made that the equipped vehicle is being operated in an urban environment; and wherein, responsive to said determination that the equipped vehicle is being operated in an urban environment, said control is inhibited from switching the headlamp of the equipped vehicle from a low-beam state to a high-beam state. - View Dependent Claims (15, 16)

17. A driver assistance system for a vehicle, said driver assistance system comprising:
-
an imager comprising a CMOS photosensor array of photosensor elements; wherein said imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle equipped with said driver assistance system, and wherein said imager has a forward field of view to the exterior of the equipped vehicle through the windshield of the equipped vehicle; wherein said CMOS photosensor array is operable to capture image data; a control comprising an image processor; wherein said driver assistance system controls switching a headlamp of the equipped vehicle from a low-beam state to a high-beam state via processing of captured image data by said image processor; wherein, at least in part responsive to processing of captured image data by said image processor, a determination is made that the equipped vehicle is being operated in an urban environment; wherein, responsive to said determination that the equipped vehicle is being operated in an urban environment, said control is inhibited from switching the headlamp of the equipped vehicle from a low-beam state to a high-beam state; wherein said imager comprises a lens and a spectral filter, and wherein said spectral filter is disposed between said lens and said CMOS photosensor array of photosensor elements, and wherein light emitted by sources external of the equipped vehicle and/or reflected by objects external of the equipped vehicle passes through, and is filtered by, said spectral filter to be incident on at least some of said photosensor elements of said CMOS photosensor array, and wherein said spectral filter comprises a red filter that passes visible light of wavelength generally in the red portion of the visible spectrum and that substantially attenuates light having wavelengths generally outside the red portion of the visible spectrum; and wherein said CMOS photosensor array of photosensor elements comprises an array of rows and columns and wherein at least one of (i) the number of columns exceeds 512, (ii) the number of rows exceeds 512 and (iii) said CMOS photosensor array of photosensor elements comprises at least 262,144 photosensor elements. - View Dependent Claims (18, 19, 20)
