Zusammenfassung:	Embodiments of the present invention provide a method and a device for positioning vehicle. The method includes steps of: obtaining preset first map data and second map data acquired in real time; determining a first semantic element according to the first map data, and determining first direction information and first position information corresponding to the first semantic element; determining a second semantic element according to the second map data, and determining second direction information and second position information corresponding to the second semantic element; determining optimal heading information of the vehicle according to the first direction information and the second direction information; and determining optimal position information of the vehicle, according to the first position information, the second position information, and the optimal heading information. The determining of the optimal heading information and optimal position information is achieved by the embodiments of the present invention. Positioning error of the vehicle is reduced by performing the positioning based on the optimal heading information and the optimal position information and positioning accuracy of the vehicle is improved.
