Embodiment Construction

[0035] Below in conjunction with accompanying drawing, invention is described in further detail.

[0036] refer to figure 1 , figure 1 It is a schematic diagram of the in-vehicle system in an embodiment of the in-vehicle navigation method of the present invention. The vehicle 11 includes a vehicle-mounted fixed processing terminal 12 , a mobile processing terminal 13 and an in-vehicle control system 17 . The vehicle fixed processing terminal 12 includes: an in-vehicle data reading device 15 , a GPS navigation module 19 , an inertial navigation module 14 and a navigation processing and output module 110 .

[0037] Wherein, the input terminal of the navigation processing and output module 110 is connected with the output of the GPS navigation module 19 and the inertial navigation module 14 . The GPS navigation module 19 is configured to obtain current GPS navigation data and send the current GPS navigation data to the navigation processing and output module 110 . An input en...

Abstract

The invention discloses a vehicle navigation method. The method comprises the steps of judging GPS positioning status information in current GPS navigation data to determine whether the current GPS navigation data are usable navigation data or not, achieving navigation according to the current GPS navigation data, or, obtaining inertial navigation data according to history GPS navigation records and vehicle running data and achieving navigation according to the inertial navigation data. Therefore, the problem that due to the influence of covering landforms in the GPS vehicle navigation process, vehicle navigation cannot be achieved is solved. The usability and accuracy of vehicle navigation under various landforms and position environments are improved, the service environment of a vehicle navigation system is expanded, and accordingly the reliability and safety of vehicle navigation when vehicle navigation is in use are improved.

Description

technical field [0001] The invention relates to a navigation method, in particular to a vehicle navigation method, a system and a vehicle mobile navigation terminal. Background technique [0002] With the continuous development of communication technology and the automobile industry, vehicle navigation devices are widely used in various vehicles. Global satellite positioning technology (GPS), as a commonly used technology in the existing vehicle navigation, has been widely used in the process of realizing the existing vehicle navigation. navigation. [0003] Since the GPS message is received in real time according to the current location of the vehicle during the navigation process of the vehicle navigation through the GPS system, therefore, when the vehicle is in caves, underground, etc. In the environment where the signal cannot be effectively transmitted, the GPS navigation system will not be able to receive GPS messages, and eventually the driver of the vehicle cannot ...
