Detailed Description
For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.

The terms "first," "second," and the like, as used in embodiments of the present disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
In the related art, when positioning and navigating, location information is usually determined based on longitude and latitude, that is, an existing navigation system is established based on longitude and latitude representing location information, and in road management, location information is represented by a road scale such as a stake mark, for example, stake mark 01G25K221200 represents a location of "up-going G25 highway 221 km more than 200 meters".
The longitude and latitude coordinate position information is applied to road management, is not vivid and concrete, and the road scale position information is applied to positioning and navigation, so that reading and processing of a machine are inconvenient, and obviously, the vehicle-road cooperation method in the related technology cannot realize accurate intercommunication between the longitude and latitude coordinate position information and the road scale position information.
In view of the above, the disclosure is directed to a vehicle-road cooperation method.
Referring to fig. 1, a schematic flow chart of a vehicle-road collaboration method according to an embodiment of the disclosure is shown. The vehicle-road cooperation method is realized through a road end system and a vehicle navigation system; the information in the road end system is information constructed based on the position of the road scale, and the information in the vehicle navigation system is information constructed based on the position of longitude and latitude coordinates; the method comprises the following steps:
s110, the vehicle-mounted navigation system converts information constructed based on the longitude and latitude coordinate position into information constructed based on the road scale position based on the road scale and the longitude and latitude coordinate conversion library, and sends the information to the road end system.
In some embodiments, the vehicle-mounted navigation system comprises vehicle basic information, positioning information and route information. The vehicle basic information, the positioning information and the route information are information constructed based on longitude and latitude coordinate positions.
In navigation, the location information of an object is generally described using latitude and longitude coordinate positions. Longitude and latitude are the sum of longitude and latitude, and both form a coordinate system called geographic coordinate system, which is a spherical coordinate system that uses a sphere of three-dimensional space to define a space on the earth and can mark any position on the earth.

In road management, the managed location is typically described in terms of a road scale location. As one example, the road scale refers to a stake number. Along the road advancing direction, the stake marks at the start point are k0.000, and a stake mark can be made at regular intervals (for example, 100 meters). For example: the start pile number of a road segment in a certain road is K200.500, and the end pile number is K350.800 (road segments K200.500-K350.800), meaning: the highway starts at 200 km and passes 500 m again, and the highway passes the road at 350 km and passes 800 m again. Wherein K is kilometers/kilometer. Further, for a specific road, the stake marks are often accompanied by more specific information, for example 01G25K221200 represents "up G25 highway 221 km more than 200 meters".
The road base information includes, but is not limited to: length information, width information, lane number information, lane change information, bifurcation information, traffic light information, and the like.
