Lane line recognition apparatus
First Claim
1. A lane line recognition apparatus comprising:
- an imaging unit mounted in a vehicle and configured to capture an image of a travel lane;
a lane-line detector configured to detect left-side and right-side lane lines that define the travel lane based on the image captured by the vehicle-mounted camera;
an abnormality determiner configured to determine whether or not a width of the travel lane defined by the left-side and right-side lane lines detected by the lane-line detector is abnormal;
a lane-line recognizer configured to, when it is determined by the abnormality determiner that the width of the travel lane is not abnormal, recognize both of the left-side and right-side lane lines in a both-side line recognition mode, and when it is determined by the abnormality determiner that the width of the travel lane is abnormal, recognize one of the left-side and right-side lane lines in a one-side line recognition mode,wherein in the one-side line recognition mode, the lane-line recognizer is configured to, for each of the left-side and right-side lane lines detected by the lane-line detector, calculate two or more parameters, of parameters representing positions of the vehicle in the travel lane relative to the lane line and parameters representing a shape of the lane line, then integrate recognition results for the respective two or more parameters are integrated, and based on the integrated recognition results of the left-side and right-side lane lines, select one of the left-side and right-side lane lines to be recognized;
wherein the lane-line detector, the abnormality determiner, and the lane-line recognizer are all being performed by one or more processors.

Abstract
In a lane line recognition apparatus, an abnormality determiner is configured to determine whether or not a width of a travel lane defined by left-side and right-side lane lines is abnormal, and a lane-line recognizer is configured to, when the width of the travel lane is not abnormal, recognize both of the left-side and right-side lane lines in a both-side line recognition mode, and when the width of the travel lane is abnormal, recognize one of the lane lines in a one-side line recognition mode. In the one-side line recognition mode, the lane-line recognizer is configured to, for each of the left-side and right-side lane lines, calculate two or more parameters of the lane line, and then integrate recognition results for the respective two or more parameters, and based on the integrated recognition results of the left-side and right-side lane lines, select one of the lane lines to be recognized.
