Automatic driving navigation method, device, system, vehicle-mounted terminal and server

Abstract

An automatic driving navigation method, device, system, vehicle-mounted terminal, and server, the method comprising: a wireless base station in a wireless network sends a differential positioning correction number to the vehicle-mounted terminal (202); the vehicle-mounted terminal acquires satellite positioning data of the vehicle, The wireless base station receives the differential positioning correction number, uses the differential positioning correction number to correct the satellite positioning data, and obtains the high-precision position of the vehicle, and the vehicle-mounted terminal sends the high-precision position to the server (204); the server receives the high-precision position from the vehicle-mounted terminal, according to The high-precision position is combined with the high-precision map information to determine the lane-level planned driving route, and the server sends the lane-level planned driving route to the vehicle-mounted terminal (206); the vehicle-mounted terminal receives the lane-level planned driving route from the server. The vehicle plans a driving path at the lane level for automatic driving (208). The use of satellite differential positioning technology based on wireless network assistance realizes all-weather and all-road automatic driving navigation, and the positioning accuracy does not need to rely on 3D high-precision maps, and the adaptability and reliability of the solution are significantly increased.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to an automatic driving navigation method, device, system, vehicle-mounted terminal and server. Background technique [0002] With the development of Internet of Things technology and the increasing seriousness of casualties, congestion, and inefficiency in traditional transportation, autonomous driving technology has become a research hotspot. [0003] In an existing automatic driving navigation method, 64-line laser radar and 3D high-precision map are used to realize vehicle positioning and navigation. The specific plan is as follows: use conventional global positioning system (English: Global Positioning System; abbreviation: GPS) technology to obtain the rough location information of the vehicle, and use 64-line laser radar to scan in real time to obtain such as buildings, landmarks, etc. The 3D image of the fixed object; then, according to the above rough pos...
