Abstract
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.
