Driver assistance system for a vehicle

摘要

A driver assistance system for a vehicle includes a forward facing camera and a control comprising an image processor that processes image data captured by the forward facing camera. The control receives vehicle data relating to the vehicle, including vehicle speed and vehicle steering angle, via a vehicle bus of the vehicle. Via processing by the image processor of image data captured by the forward facing camera, the control is operable to detect a road marking on the road being traveled by the vehicle and to the left of the vehicle. Responsive at least in part to processing of captured image data by the image processor, the control determines a driving condition of the vehicle, such as the type of lane markers present ahead of the vehicle, a traffic condition at or ahead of the vehicle, and/or a hazardous condition at or ahead of the vehicle.

主权项

1. A driver assistance system for a vehicle, said driver assistance system comprising:
a forward facing camera disposed at or in a vehicle equipped with said driver assistance system, said forward facing camera having a field of view that, when the equipped vehicle is traveling on a road, encompasses the road ahead of and to the left of the equipped vehicle; wherein the equipped vehicle is a left-hand drive vehicle; a control disposed at or in the equipped vehicle and comprising an image processor; wherein image data captured by said forward facing camera is processed by said image processor; wherein said image processor processes data at a processing speed of at least about 30 MIPS; wherein said control receives vehicle data relating to the equipped vehicle via a vehicle bus of the equipped vehicle, said vehicle data including vehicle speed and vehicle steering angle; wherein, via processing by said image processor of image data captured by said forward facing camera, said control is operable to detect a road marking on the road being traveled by the equipped vehicle and to the left of the equipped vehicle; wherein said image processor utilizes a lane marker type recognition algorithm to classify the detected road marking to be one of (i) a single solid line, (ii) a single dashed line and (iii) double lines; wherein, responsive to classification by the lane marker type recognition algorithm of the detected road marking to be double lines and not to be either a single solid line or a single dashed line, (a) said control determines ability to pass safely to the left of the equipped vehicle when the double lines are determined to be a solid line and an adjacent dashed line with the adjacent dashed line being closer to the equipped vehicle than the solid line, and (b) said control determines a non-encroachment/no-passing zone to exist to the left of the equipped vehicle when the double lines are determined to be two solid lines, and (c) said control determines a non-encroachment zone to exist to the left of the equipped vehicle when the double lines are determined to be a solid line and an adjacent dashed line with the adjacent dashed line being farther from the equipped vehicle than the solid line.
