Vehicle lamp system

摘要

A vehicle lamp system includes a camera which generates image information in a front region, a controller which generates a light distribution command for instructing a light distribution pattern based on the image information, a headlight which irradiates the front region such that the instructed light distribution pattern is obtained, and a position calibrator which detects a positional deviation between the camera and the headlight. The position calibrator detects a reference object based on the image information and measures a luminance of the reference object, and when there is a certain difference between a luminance of the reference object obtained from one light distribution pattern and a luminance of the reference object obtained from another light distribution pattern in which a light quantity of only a part is different from the one light distribution pattern, detects the positional deviation using a position of the part.

主权项

1. A vehicle lamp system comprising:
a camera configured to take an image of a region in front of a vehicle to generate image information; a controller configured to generate a light distribution command for instructing a light distribution pattern to be formed in the region in front of the vehicle based on the image information from the camera; a headlight configured to irradiate the region in front of the vehicle such that the instructed light distribution pattern is obtained, based on the light distribution command; and a position calibrator configured to detect a positional deviation between the camera and the headlight, wherein the position calibrator is configured to execute:
detecting a reference object on a road based on the image information and measuring a luminance of the reference object; andwhen there is a certain difference between a luminance of the reference object obtained from one light distribution pattern and a luminance of the reference object obtained from another light distribution pattern in which a light quantity of only a part of the another light distribution pattern is different from the one light distribution pattern, detecting the positional deviation using a position of the part.
