Patent Images
1. A vehicle lane detector that detects a lane sign on a road surface, whereina condition for determining that the lane sign is detected is changed based on one of a frequency and a ratio of detection error of the lane sign, andthe condition for determining that the lane sign is detected is changed to be stricter when one of the frequency or the ratio of the detection error of the lane sign is high compared with when one of the frequency and the ratio of the detection error of the lane sign is low.

14. A method for detecting a lane sign on a road surface, comprising:
-
changing a condition for determining that the lane sign is detected, based on a frequency of detection error of the lane sign; and determining whether the lane sign is detected, using the condition, wherein the condition for determining that the lane sign is detected is changed to be stricter when the frequency of the detection error of the lane sign is high compared with when the frequency of the detection error of the lane sign is low.
