摘要：PROBLEM TO BE SOLVED: To estimate whether a road where one's own vehicle travels is right-hand traffic or left-hand traffic, and estimate the number of traffic lanes of the road to carry out optical axis control according to the results of the estimation, in a vehicle headlight control device mounted on the vehicle. SOLUTION: Whether a light source of a different vehicle shown on a shot image on the front part of the vehicle is the light source of a leading car or the light source of a car coming from the opposite direction is detected (a step 120). Position coordinates of the different vehicle are detected (a step 130) from the light source of the different vehicle shown on the shot image. Whether the traffic is right or left is estimated on the basis of whether the position coordinates of the different vehicle are right or left relative to the front direction (a step 140). The number of the traffic lanes is estimated on the basis of whether the different vehicle is the leading car or the car coming from the opposite direction, and on the position coordinates of the different vehicle (a step 150). On the basis of the results of the estimation, variation tolerance in right and left directions of the optical axis is changed (a step 150). COPYRIGHT: (C)2013,JPO&INPIT
