The invention provides an automobile positioning system and method and an automobile, and relates to the field of automobile positioning. According to the system, a first reference coordinate, a second reference coordinate and a third reference coordinate are respectively obtained by a laser range finder, a millimeter-wave radar and a camera under respective reference coordinate systems; a first positioning coordinate, a second positioning coordinate and a third positioning coordinate are obtained by combining the coordinates of the laser range finder, the millimeter-wave radar and the camerain a geodetic coordinate system; a first coordinate conversion parameter, a second coordinate conversion parameter and a third coordinate conversion parameter are respectively obtained, so that a central control unit can fuse the coordinate data of the laser range finder, the millimeter wave radar and the camera according to the first coordinate conversion parameter, the second coordinate conversion parameter and the third coordinate conversion parameter to position the automobile. According to the automobile positioning system and method and the automobile, the positioning cost of the automobile in the target application scene can be reduced.
