Patent ID: 7751958

Claim:
A white-line display apparatus for a vehicle, comprising: road surface detecting means for detecting a road surface on which a vehicle travels; white-line recognizing means for recognizing white lines on left and right sides of a the detected road surface; lane-deviation determining means for determining whether or not the vehicle deviates, or is likely to deviate, from a lane defined by the white lines, based on at least a relative position between the vehicle and the white lines recognized by the white-line recognizing means; display means for displaying the white lines on left and right sides thereof based on a recognition result by the white-line recognizing means; and white-line-display changing means for changing display of the white lines by the display means based on a determination result of the lane-deviation determining means; wherein, when the lane-deviation determining means has determined that the vehicle does not deviate, or is not likely to deviate, from the lane, the white-line-display changing means represents each of the left and right white lines displayed by the display means as a figure inclined by a predetermined angle toward a center of the display means with respect to a vertical axis at a top of the display means, and when the lane-deviation determining means has determined that the vehicle deviates or is likely to deviate from the lane, the white-line-display changing means represents a respective one of the left and right white lines violated by the vehicle as a figure inclined by an angle smaller than the predetermined angle.
