Abstract

The present invention provides a difference location method based on an intelligent vehicular access cooperation system and an intelligent vehicular access cooperation system. The system comprises: a road side unit configured to obtain the difference location correction parameters and broadcast the difference location correction parameters to a vehicle unit in a presetting range; and the vehicle unit configured to obtain original location data of the vehicle unit and correct the original location data based on the difference location correction parameters to obtain the final location data of the vehicle unit. The difference location method based on the intelligent vehicular access cooperation system and the intelligent vehicular access cooperation system are able to realize the difference location function in the intelligent vehicular access cooperation system with no need for the disposition of extra base stations, the addition of extra network access devices and the adoption of a mobile operator or an Internet, ensure the stability of the network state and save the device cost and the flow cost.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to an intelligent vehicle-road coordination system, and a differential positioning method based on the intelligent vehicle-road coordination system. Background technique [0002] With the development of vehicle driving automation, precise vehicle positioning has gradually become an important technology for assisted driving and automatic driving. Among the existing satellite positioning systems, such as the GPS (Global Positioning System, Global Positioning System) of the United States, the GLONASS (Glonass satellite navigation system) of Russia, and the Beidou system of China, although they can provide positioning accuracy at the centimeter level , but it is not open to civilian use, and the positioning accuracy of a real civilian positioning system is about tens of meters or even tens of meters. Such accuracy is far from meeting the requ...
