The invention discloses a vehicle positioning and navigation method and device as well as related systems and applications. The method includes: in an adjacent road environment, acquiring the navigation signal strengths of multiple vehicles within a preset range in the adjacent road environment; The adjacent road environment includes the first road and the second road; if the navigation signal strength of the first road is weaker than the navigation signal strength of the second road, it is judged that the location is on the first road but the navigation signal strength does not meet the first road. Vehicles with road navigation signal strengths are incorrectly located. This technical solution obtains the navigation signal status information of multiple vehicles within the preset range in the adjacent road environment, and according to the road attribute information in the map data, after a series of processing and calculations, the navigation can be positioned at the correct position, improving It improves the accuracy of vehicle positioning, provides a better guarantee for the driver's driving safety, and improves the user experience.
Description
technical field [0001] The present invention relates to the technical field of navigation, in particular to a vehicle positioning and navigation method and device, as well as related systems and applications. Background technique [0002] At present, with the rapid development of the navigation field, the current navigation software is gradually improving, but there is a problem that has caused many navigation software manufacturers a headache, that is, the matching of main and auxiliary roads with ramps. Most of the existing solutions are based on the global navigation satellite system (Global Navigation Satellite System, GNSS) positioning track to determine the matching, and the navigation positioning is likely to yaw, giving the user a very bad driving experience. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a vehicle positioning and navigation method and device, related systems and applications that over...
