Abstract

The invention discloses a positioning method and system based on internet of vehicles, and belongs to the field of internet of vehicles. The method comprises the steps of enabling a roadside unit to acquire observed quantity information of a target vehicle, wherein the target vehicle is an information-authenticated vehicle; performing differential calculation based on the observed quantity information of the target vehicle by using a preset virtual reference station to obtain enhanced position information of the target vehicle, wherein the preset virtual reference station is one or more roadside units in a target area; and based on the enhanced position information, obtaining accurate position information of the target vehicle. By adopting the positioning method and system based on the internet of vehicles provided by the embodiment of the invention, high-precision positioning of the vehicle can be implemented and / or the information attack such as signal masquerading and signal inducing can be identified.

Description

technical field [0001] The present application relates to the field of the Internet of Vehicles, in particular to a positioning method and system based on the Internet of Vehicles. Background technique [0002] Intelligent Connected Vehicle, or ICV (full name Intelligent Connected Vehicle), refers to the organic combination of Internet of Vehicles and smart vehicles. It is equipped with advanced on-board sensors, controllers, actuators and other devices, and integrates modern communication and network technologies to realize the It is a new generation of vehicles that can exchange and share intelligent information with people, vehicles, roads, backgrounds, etc. to achieve safe, comfortable, energy-saving, and efficient driving, and can eventually replace humans. With the development of intelligent networked vehicles, accurate and reliable positioning of vehicles is a necessary condition for realizing automatic driving or unmanned driving and intelligent network connection. ...
