Abstract

The invention discloses a vehicle navigation method, a position marking method, an apparatus, and a system, and belongs to the technical field of vehicle navigation. The vehicle navigation method comprises: acquiring the vehicle motion data collected by a vehicle-mounted diagnosis system OBD; drawing a vehicle motion trajectory according to the vehicle motion data; matching vehicle motion trajectory with a map; and displaying the trajectory motion trajectory in the map according to the matching result. According to the present invention, the problem that the vehicle navigation cannot be performed in the region having the poor GPS signal even having no GPS signal is solved; and the vehicle motion trajectory can be drawn according to the vehicle motion data collected by OBD without the GPS signal, and the vehicle navigation effect can be achieved by combining with the map.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle navigation, in particular to a method, device and system for vehicle navigation and position marking. Background technique [0002] GPS (Global Positioning System, Global Positioning System) is a system for locating and navigating objects by means of GPS positioning satellites, and is widely used in vehicle navigation. [0003] When GPS is used for vehicle navigation, the GPS positioning module in the vehicle determines the current longitude and latitude of the vehicle according to the GPS signals sent by at least four GPS positioning satellites, and displays them in real time on the map, thereby realizing vehicle navigation. [0004] In the process of implementing the embodiments of the present invention, the inventors found that the above-mentioned technology has at least the following problems: [0005] In some areas with poor or no GPS signal, such as underground parking...
