Embodiment 1

[0028] Such as figure 1 As shown, Embodiment 1 provides a navigation system, including: a handheld display unit, which is suitable for detachable installation in the control position of the car; the navigation unit of the navigation system is located in the car center console, and the navigation unit The built-in wireless module is connected with the handheld display unit; the navigation unit includes: a processor module, a first and a second GPS module, and the first and second GPS modules are connected with the processor module through a channel selection module.

[0029] The channel selection module is controlled by the processor module and used for switching between the first and second GPS modules.

[0030] Specifically, the handheld display unit includes: a touch screen, a slave processor module connected to the touch screen, and a slave wireless module connected to the slave processor module. That is, the handheld display unit can display navigation unit operations, na...

Embodiment 2

[0050] On the basis of Embodiment 1, Embodiment 2 provides a working method of the navigation system.

[0051] The navigation system includes a navigation unit, which includes: a processor module, a data storage module, first and second GPS modules, and the first and second GPS modules are connected to the processor module through a channel selection module; the data The storage module stores map data and vehicle type turning radius data; the working method includes: the processor module is adapted to plan a navigation route according to the current location of the vehicle and the input target location, and combined with the turning radius data of the current vehicle.

[0052] The processor module is adapted to pre-calculate several preliminary planning navigation paths between the vehicle's current location and the input target location; and search for corresponding curved road sections in each preliminary planning navigation path, and turn The radius data filters each curved...

Embodiment 3

[0058] Such as Figure 3a , Figure 3b and Figure 3c As shown, on Embodiment 1, Embodiment 3 provides a vehicle.

[0059] The front of the vehicle is provided with multiple rows of front wheels, and each row of front wheels corresponds to an independent steering device and a driving device, and each steering device and driving device are connected to a vehicle-mounted electronic ECU system, and the vehicle-mounted electronic ECU system is connected to the vehicle-mounted electronic ECU system. connected to the navigation system.

[0060] The vehicle-mounted electronic ECU system is connected with the vehicle-mounted panoramic camera device, and photographs the turning posture of the vehicle, specifically detects whether the vehicle is in the current lane, and feeds back the detection result to the vehicle-mounted electronic ECU system.

[0061] When the vehicle enters a curve, it first uses the first row of front wheels as the main steering wheel to make a turning action, ...

Abstract

The invention relates to a navigation system, a working method and an automobile adopting GPS redundant design. The navigation system comprises a handheld display unit which is suitable for being installed at the center control position of the automobile in a separable mode; a navigation unit of the navigation system is located inside a center console of the automobile and connected with the handheld display unit through a built-in wireless module; the navigation unit comprises a processor module, a first GPS module and a second GPS module, and the first GPS module and the second GPS module are connected with the processor module through a channel selection module. The navigation system and the working method thereof adopt the redundant design, and in this way, the reliability of the navigation system is improved; the handheld display unit and the navigation unit are separated, a user can check navigation paths conveniently in a handholding mode, and the navigation system is particularly suitable for a passenger who sits at the co-driver position to help the driver to perform navigation.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a navigation system with GPS redundant design, a working method and a vehicle with the navigation system installed. Background technique [0002] Many cars are equipped with on-board navigation terminals to provide information such as location, speed and time, and cooperate with high-precision navigation electronic maps to provide users with navigation services, helping users to plan driving routes on the electronic map accurately and in real time, and at the same time guide The device on which the user arrives at the destination according to the planned route. [0003] However, the vast majority of car navigation terminals use GPS to achieve navigation and positioning, but this technology originated in the United States and has certain limitations. [0004] Therefore, it is necessary to design a stable and reliable vehicle navigation system. Contents of the invention [0005] The p...
