Problems solved by technology

[0004] However, this positioning technology can meet the positioning accuracy requirements (such as sub-meter level) in scenes with good GNSS signals such as highways and open suburbs, but in environments with poor GNSS signals such as dense urban scenes with severe occlusion, tunnels, and garages , it cannot meet the requirements of positioning accuracy

Abstract

The invention provides a positioning method and device and electronic equipment, and relates to the technical field of Internet of Vehicles. The method comprises the steps that a first road side unit and other road side units in a plurality of road side units synchronously send data frames, and the data frames comprise positioning information, so that a passing vehicle-mounted terminal determines the current position of a vehicle according to the positioning information; wherein the positioning information comprises position information of the road side unit sending the data frame. The positioning information required by the vehicle is directly from the roadside unit, and the vehicle can directly communicate with the roadside unit, so that when the GNSS signal strength of the road section where the vehicle runs is relatively poor (such as a tunnel, a garage and the like), the positioning precision of the vehicle can also meet the requirement, and the positioning precision of the vehicle in an area with relatively poor GNSS signal strength is improved.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular to a positioning method, device and electronic equipment. Background technique [0002] In recent years, with the continuous advancement of technology, vehicle wireless communication technology (Long Term Evolution-Vehicle To Everything, LTE-V2X) has been gradually applied in daily life. Positioning accuracy in V2X applications often needs to reach the meter level; in autonomous driving technology, the positioning accuracy is required to be higher, generally sub-meter or even centimeter level is required. [0003] In the related art, differential positioning technology (Differential Global Position System, DGPS) is often used for positioning. Use a Global Navigation Satellite System (GNSS) receiver to observe on the base station to receive the signal sent by the satellite; after that, the GNSS receiver calculates the distance correction number from the base s...
