Title:
AUTOPILOT NAVIGATION METHOD, DEVICE, SYSTEM, ON-BOARD TERMINAL AND SERVER
Document Type and Number:
WIPO Patent Application WO/2017/091953
Kind Code:
A1
Abstract:
Disclosed are an autopilot navigation method, device, system, on-board terminal and server. The method comprises: sending, by a wireless base station in wireless network, a differential positioning correction to an on-board terminal (202); acquiring, by the on-board terminal, satellite positioning data of a vehicle, receiving the differential positioning correction from the wireless base station in a wireless network, and performing correction on the satellite positioning data with the differential positioning correction, to obtain a high-precision position of the vehicle, and sending, by the on-board terminal, the high-precision position to a server (204); receiving, by the server, the high-precision position from the on-board terminal to determine a lane-level planned traveling path according to the high-precision position in combination with high-precision map information, and sending, by the server, the lane-level planned traveling path to the on-board terminal (206); and receiving, by the on-board terminal, the lane-level planned traveling path from the server to control the vehicle to automatically drive following the lane-level planned traveling path, according to the acquired high-precision position (208). By using the wireless network-assisted satellite differential positioning technique, all-weather and all-terrain autopilot navigation is achieved, and the accuracy of positioning is not dependent on a 3D high-precision map, so that the reliability and applicability of the scheme is significantly increased.
