Embodiment 1

[0027] 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 It is connected to the handheld display unit through the built-in wireless module.

[0028] 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, navigation settings, and data on the touch screen. The user can perform corresponding navigation operations by holding the display unit.

[0029] Both the wireless module and the slave wireless module can use WiFi modules.

[0030] Preferably, a power supply interface is provided in the vehicle central console, and when the ha...

Embodiment 2

[0048] On the basis of Embodiment 1, Embodiment 2 provides a working method of the navigation system.

[0049] 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 in combination with the turning radius data of the current vehicle. .

[0050] 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 road section, that is, obtains the planned navigation path corresponding to the curved road section suitable for this vehicle type.

[0051] The minimum turning radius r corresponding to the vehicle type is obtained from the turning radius data of the vehicle type; the processor is adapted to compare the minimum turning ...

Embodiment 3

[0056] Such as Figure 3a , Figure 3b and Figure 3c As shown, on Embodiment 1, Embodiment 3 provides a vehicle.

[0057] 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.

[0058] 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.

[0059] 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, ...
