Driver assistance system for vehicle
First Claim
1. A driver assistance system for a vehicle, said driver assistance system comprising:
- a camera configured to be disposed at a vehicle equipped with said driver assistance system;
wherein said camera, when disposed at the equipped vehicle, views through a windshield of the equipped vehicle;
wherein said camera is disposed at a windshield electronics module attached at the windshield of the equipped vehicle;
wherein said camera views forwardly through the windshield of the equipped vehicle at a location that is swept by a windshield wiper of the equipped vehicle;
said camera capturing image data of a scene forward of the equipped vehicle;
a controller comprising an image processor;
said image processor processing captured image data;
wherein said controller, responsive to said image processor processing captured image data, detects an object of interest external to the vehicle;
wherein said image processor, when processing captured image data, utilizes a blockage detection algorithm to detect at least a partial blocking condition at said camera;
wherein said controller determines a driving condition of the vehicle;
wherein, responsive to determination of a driving condition that is indicative of end of line vehicle testing of the vehicle at a vehicle assembly plant, and responsive to said image processor processing captured image data and said image processor utilizing said blockage detection algorithm, said image processor detects at least a partial blocking condition at said camera; and
wherein, during the determined end of line vehicle testing of the vehicle at the vehicle assembly plant and with the vehicle driven on rollers to check engine performance, said controller ignores the detected partial blockage condition at said camera.

Abstract
A driver assistance system for a vehicle includes a camera that, when disposed at the vehicle, views through a windshield of the vehicle. The camera is disposed at a windshield electronics module attached at the windshield of the vehicle. The camera captures image data of a scene forward of the vehicle. A control includes an image processor that processes captured image data. The control, responsive to the image processor processing captured image data, detects an object of interest external to the vehicle. The control utilizes a blockage detection algorithm and, responsive to the image processor processing captured image data, is operable to detect at least a partial blocking condition at the camera.

16. A driver assistance system for a vehicle, said driver assistance system comprising:
-
a camera configured to be disposed at a vehicle equipped with said driver assistance system; wherein said camera, when disposed at the equipped vehicle, views through a windshield of the equipped vehicle; wherein said camera is disposed at a windshield electronics module attached at the windshield of the equipped vehicle; wherein said camera views forwardly through the windshield of the equipped vehicle at a location that is swept by a windshield wiper of the equipped vehicle; said camera capturing image data of a scene forward of the equipped vehicle; a controller comprising an image processor; said image processor processing captured image data; wherein said controller, responsive to said image processor processing captured image data, detects an object of interest external to the vehicle; wherein said image processor, when processing captured image data, utilizes a blockage detection algorithm to detect at least a partial blocking condition at said camera; wherein said controller determines a driving condition of the vehicle; wherein, responsive to determination of a driving condition that is indicative of end of line vehicle testing of the vehicle at a vehicle assembly plant, and responsive to said image processor processing captured image data and said image processor utilizing said blockage detection algorithm, said image processor detects at least a partial blocking condition at said camera; wherein, during the determined end of line vehicle testing of the vehicle at the vehicle assembly plant and with the vehicle driven on rollers to check engine performance, said controller ignores the detected partial blockage condition at said camera; wherein said camera comprises a pixelated imaging array, and wherein, if either partial or total blockage is determined when the determined driving condition is not indicative of end of line vehicle testing of the vehicle, processing of captured image data by said image processor adapts to accommodate blocked pixels; and wherein said controller automatically detects that the blockage has been removed and resumes normal functionality. - View Dependent Claims (17, 18)

19. A driver assistance system for a vehicle, said driver assistance system comprising:
-
a camera configured to be disposed at a vehicle equipped with said driver assistance system; wherein said camera, when disposed at the equipped vehicle, views through a windshield of the equipped vehicle; wherein said camera is disposed at a windshield electronics module attached at the windshield of the equipped vehicle; wherein said camera views forwardly through the windshield of the equipped vehicle at a location that is swept by a windshield wiper of the equipped vehicle; said camera capturing image data of a scene forward of the equipped vehicle; a controller comprising an image processor; said image processor processing captured image data; wherein said controller, responsive to said image processor processing captured image data, detects an object of interest external to the vehicle; wherein said image processor, when processing captured image data, utilizes a blockage detection algorithm to detect at least a partial blocking condition at said camera; wherein said controller determines a driving condition of the vehicle; wherein, responsive to determination of a driving condition that is indicative of end of line vehicle testing of the vehicle at a vehicle assembly plant, and responsive to said image processor processing captured image data and said image processor utilizing said blockage detection algorithm, said image processor detects at least a partial blocking condition at said camera; wherein, during the determined end of line vehicle testing of the vehicle at the vehicle assembly plant and with the vehicle driven on rollers to check engine performance, said controller ignores the detected partial blockage condition at said camera; wherein captured image data is processed differently by said image processor depending on the determined driving condition to reduce false blockage detection; and wherein said camera comprises a pixelated imaging array, and wherein, if either partial or total blockage is determined when the determined driving condition is not indicative of end of line vehicle testing, processing of captured image data by said image processor adapts to accommodate blocked pixels. - View Dependent Claims (20)
