Embodiment Construction

[0029] The core of the present invention is to provide a positioning and navigation system, which is not affected by the strength of the network signal. Under some special conditions, such as when the GPS signal of the network positioning and navigation system is weak or the GPS signal cannot be interrupted, it can still continue to accurately monitor the vehicle. The positioning and navigation of the vehicle improves the accuracy of the positioning and navigation of the vehicle; another core of the present invention is to provide a vehicle including the above positioning and navigation system.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of th...

Abstract

The invention discloses a positioning navigation system and a vehicle. The system includes: a traffic information acquisition module, which is used for acquiring the traffic information of the road where the vehicle is located; a positioning industrial personal computer, which is used for generating first positioning information according to the traffic information and a 3D map stored in the positioning industrial personal computer itself; a central controller, which is used for acquiring vehicle navigation information according to the first positioning information. According to the positioning navigation system and the vehicle provided by the invention, during positioning navigation on the vehicle, the vehicle navigation information is acquired by means of the first positioning information obtained through the traffic information acquisition module and the prestored high precision 3D map, the positioning navigation is not affected by the strength of a network signal, and under some special conditions, like when the GPS signal of the network positioning navigation system is weak or the GPS signal is interrupted, the system still can achieve precise positioning navigation on the vehicle continuously, thus improving the precision of vehicle positioning navigation.

Description

technical field [0001] The invention relates to the technical field of vehicle positioning, in particular to a positioning and navigation system and a vehicle. Background technique [0002] At present, the network positioning and navigation system is mostly used in automobiles. The network positioning and navigation system is a navigation combination module of a multi-sensor fusion inertial navigation system. This module is based on GNSS (Global Navigation Satellite System, global satellite navigation system) and inertial measurement unit (IMU) , through the optimal Kalman filter technology for data fusion, output combined positioning and navigation information, improve the adaptability of the navigation environment, and obtain high-performance navigation capabilities. [0003] Through a large number of road test tests on the network positioning and navigation system, the results show that: in the vicinity of high-rise buildings, GNSS satellite signals are seriously blocked,...
