Problems solved by technology
[0002] In the existing navigation matching technology, it is troublesome to match the vehicle logo on the small fork intersection road, and there are generally the following situations: 1. In the case of a guiding route, if the vehicle actually drives according to the guiding route, generally The navigation can be matched on the correct road; but if the vehicle does not actually drive according to the guiding route, the general navigation will be matched according to the guiding route, and the route will not be re-planned, that is, the wrong matching phenomenon will occur in the navigation; In the case of no guidance route, the general navigation will match the optimal candidate road in the navigation algorithm, and the selection of the optimal candidate road will mainly refer to the vertical distance between the vehicle position point and the candidate road provided by the hardware, the road direction and the vehicle provided by the hardware. direction, and because there will be certain errors in the road data itself, there will also be certain errors in the vehicle position information provided by the hardware. Therefore, the optimal supplement in the navigation algorithm may not be the actual driving road of the vehicle, that is, the navigation match error

The invention discloses a precisely matching navigation method and a precisely matching navigation method for a high-speed area. The precisely matching navigation method for the high-speed area comprises the following steps: determining a current position of a terminal; extracting high-speed area data in a predetermined area range of the current position, matching the current position of the terminal and the high-speed area data, and determining a position relationship; acquiring state information of the terminal according to the position relationship; judging a road at which the current position of the terminal is positioned; displaying a mark of the terminal on the determined road. By adopting the method, a specific position of current text of the terminal in the high-speed area can be judged precisely, such as a main road of an expressway or a branch road which enters into a service area; the current position is displayed on a map more precisely; the matching precision is improved;moreover, the moving trend of the terminal can also be determined; guide can be provided for a user better; the driving safety is improved.
