Problems solved by technology

[0003] However, for areas with complex road conditions, there will still be a certain vehicle position error only through the current position coordinate information, and the positioning accuracy is low
For example, if the current GPS position of the vehicle is on the adjacent border of two adjacent areas, it will not be possible to confirm which area the vehicle is in

Abstract

The present invention relates to a vehicle positioning method and device. The method comprises the following steps: acquiring the current position coordinates of the vehicle, and selecting a candidate area within a preset distance according to the current position coordinates of the vehicle; acquiring the historical position of the vehicle within a preset time Coordinates, and select the first candidate area from the candidate areas according to the historical position coordinates of the vehicle; determine whether the vehicle enters the first candidate area, so as to determine the current position of the vehicle. The present invention obtains accurate vehicle position information through historical driving track information and current coordinate information of the vehicle. The present invention is simple and easy to implement, and has high positioning accuracy.

Description

technical field [0001] The invention relates to the technical field of vehicle positioning, in particular to a vehicle positioning method and device. Background technique [0002] With the rise of Internet cars, various new car services have emerged. After the user requests the car location service, it is necessary to locate and find the user's car accurately and quickly. In traditional GPS (Global Positioning System, Global Positioning System), BDS (Beidou Navigation Satellite System, BeiDou Navigation Satellite System) and other positioning methods, the current position coordinates of the vehicle are usually used to locate the vehicle. [0003] However, for areas with complex road conditions, there will still be a certain vehicle position error only through the current position coordinate information, and the positioning accuracy is low. For example, if the current GPS position of the vehicle is on the adjacent boundary of two adjacent areas, it will not be possible to c...
