The present invention relates to a vehicle positioning method, a vehicle, and a vehicle positioning system capable of more precise positioning in an ADAS or semi-autonomous driving vehicle that is simply equipped with a camera and a GPS device without expensive sensors or equipment. The vehicle positioning method of the present invention includes steps of: calculating first position information of a positioning vehicle; extracting objects on the road; receiving second position information of surrounding vehicles of the first position information from an LDM server; matching a dynamic object among the extracted objects with a vehicle of the second position information; calculating a first predicted position of the positioning vehicle based on the second position information; matching a static object among the extracted objects with a high-definition map (HD Map) to detect third position information on the high-definition map of the static object; calculating a second predicted position of the positioning vehicle based on the third position information; and calculating positioning information of the positioning vehicle based on the first predicted position and the second predicted position. 본 발명은 고가의 센서나 장비를 구비하지 않고 단순히 카메라와 GPS장치가 장착되고 ADAS혹은 반자율 주행이 가능한 차량에 있어서 보다 정밀한 측위가 가능한 차량 측위방법 및 차량 측위 시스템에 관한 것이다.
