The driver can only drive with the single navigation information. The driver can only visually observe the road conditions ahead, and also needs to manually adjust the driving behavior and vehicle status; and such navigation instruments are used under complex road conditions, and there is no more road navigation information. For example, when the vehicle is driving in the field, the engineering vehicle is driving on an unpaved road, and the road conditions are complex, such navigation instruments cannot perform effective road navigation; and the existing vehicles that use laser radar for assisted automatic driving are more likely to directly apply road condition information to the program algorithm, and directly operate the vehicle through the program algorithm, and cannot be displayed on the navigation instrument for the driver to understand the road conditions ahead and make timely adjustments.

[0041] like Fig.11 As shown, the navigation control part 02 includes a controller 131, a radar display 132, a voice announcer 133 and a code display 134.

[0042] The specific installation method of the navigation control part 02 of the vehicle navigation system with monitoring and adjustment functions is as follows: the navigation control part 02 can be installed on the center console in the vehicle through the controller 131, and the control circuit and signal line of the controller 131 are connected to the road condition monitoring part 01, and the control circuit, signal line and power circuit of the controller 131 are connected to the vehicle power supply, the vehicle computer and the external computer.

[0043] 1. A specific posture adjustment method of the road condition monitoring part 01 of the vehicle-mounted navigation system with monitoring and adjustment functions: 1. By controlling the operation of the dual-axis motor 81, the dual-axis motor 81 can drive the connecting shaft 82 to rotate through the first gear transmission assembly 83, and the connecting shaft 82 can drive the bevel gear ring 6 to rotate through the second gear transmission assembly 84. The bevel gear ring 6 will drive the rotating ring 5 and the connecting arm 7 to rotate. The connecting arm 7 will increase the height of the monitoring device 12, so that the monitoring device 12 can have a higher road condition monitoring field of view. While the connecting arm 7 rotates, the follower rod 103 will be limited and pulled by the connecting rod 93, the fixed shaft 91, the first crankshaft joint 92 and the fine-tuning device 11, so that the follower rod 103 drives the second crankshaft joint 102 to maintain its position through the follower shaft 101, and the follower shaft 101 will rotate, so that the follower shaft 101 drives the follower sleeve 121 and the installation cabin 125 to maintain a leftward angle, so that the monitoring device 12 can maintain a working state of scanning and monitoring the road condition in front of the vehicle under the rotation and lifting action of the connecting arm 7.

[0044] 2. The operation of the electric push rod 111 can also be controlled so that the telescopic part of the electric push rod 111 drives the follower rod 103 to move through the interconnected shaft 112, and the follower rod 103 drives the follower shaft 101 to rotate independently through the second crankshaft 102, thereby controlling the precise direction angle of the monitoring device 12, so that the monitoring device 12 can scan and monitor the road condition at a certain distance in front of the vehicle, so that the vehicle can have more accurate road condition scanning and monitoring information when it is driving at a low speed on a complex road condition.

[0045] 3. When the vehicle is traveling in a jungle or an area with height restrictions, the scanning radar 126 will also identify whether the monitoring device 12 is in a position to collide with an obstacle at a certain height in front. At this time, the scanning radar 126 will control the operation of the dual-axis motor 81 through the controller 131 and the external computer, so that the connecting arm 7 drives the monitoring device 12 to lower its height to pass through and avoid collision, thereby realizing the adaptive adjustment of the road condition monitoring part 01.

[0046] 4. When the vehicle needs to travel at a low speed on a complex road or in a traffic jam, the driving device 8 can be controlled to drive the connecting arm 7 to put the monitoring device 12 in the highest position, so that the monitoring device 12 has a higher monitoring orientation and thus has a farther monitoring field of view.

[0047] 5. When the vehicle is on a paved road with good road conditions, the vehicle can travel at high speed. At this time, the driving device 8 can be controlled to drive the connecting arm 7 to make the monitoring device 12 in the lowest position, thereby reducing the area of ​​the windward cross-section of the road condition monitoring part 01 and reducing the wind resistance of the road condition monitoring part 01 to the vehicle when it is traveling at high speed. At this time, the unfolded monitoring device 12 can continue to be used to monitor the road condition; if there is no need to monitor and navigate the road condition by the monitoring device 12, the driving motor 123 can be controlled to operate, so that the driving motor 123 drives the rotating shaft 122 to rotate through the third gear transmission assembly 124, so that the rotating shaft 122 drives the installation cabin 125 to rotate, and the installation cabin 125 rotates to contact the front and rear sides of the connecting arm 7, thereby reducing the windward area of ​​the installation cabin 125, and then further reducing the area of ​​the windward cross-section of the road condition monitoring part 01, further reducing the wind resistance of the vehicle when traveling.

[0048] 2. The vehicle navigation system with monitoring and adjustment functions monitors and navigates the road conditions: The scanning radar 126 is started, and the scanning radar 126 will emit sonar signals in a scanning manner in the direction of the vehicle's advance. The sonar signals will generate echoes after irradiating the road surface in front of the vehicle. The scanning radar 126 receives the sonar echoes, and different road conditions will generate echoes in different forms, that is, there are differences between the echo signals generated by different road conditions. The echoes with differences received by the scanning radar 126 will be analyzed and calculated by the program of the external computer, and the echo signals will be converted into other signals to navigate the driver to the road conditions ahead, such as a position signal that can be displayed on the radar display 132, a sound signal that needs to be acted on the voice announcer 133 to inform the driver after the echo analysis, and a code signal that needs to be displayed on the code display 134 using different codes to prompt the driver after the echo analysis; according to the above-mentioned working process of the scanning radar 126, through the difference of the echo signals and the data comparison and analysis and calculation of the external computer, the difference of the echo signals can be output as different other signals and act on different navigation guidance components, that is, the different output signals are converted into different navigation methods.

[0049] 3. Examples of road condition monitoring and road condition navigation methods of the vehicle navigation system with monitoring and adjustment functions: 1. Navigation of road conditions ahead of the vehicle: After the scanning radar 126 transmits the sonar signal in a scanning manner, the sonar signal irradiates the vehicle's forward direction with relatively different road echo signals, that is, the sonar signal irradiates the paved road, unpaved road, flooded road, gravel road, sandy road and other road surfaces, and the reflected echoes are different. After being received by the scanning radar 126, the differential echoes are converted into signals recognizable by an external computer. The external computer compares and analyzes the differential echo signals through big data, and can accurately derive that the echo signal is a road condition that requires different driving methods at a certain distance in the vehicle's forward direction, that is, the scanning radar 126 can monitor the presence of an unpaved road ahead of the vehicle. After analyzing the content represented by the signal, the external computer will convert the signal through a program and output it to the voice announcer 133 or the code display 134, and inform the driver of the difference in the road conditions ahead or the road conditions ahead with a specific voice announcement and a specific code; in addition, the scanning radar 126 can be controlled by the controller 131, the external computer and the on-board computer to control the vehicle's driving speed when it recognizes different road surfaces, that is, if the scanning radar 126 recognizes an unpaved road, the controller 131, the external computer and the on-board computer will control the vehicle's driving speed to be reduced according to the program settings, so as to realize the monitoring and navigation of the road conditions and the speed adjustment of the vehicle.

[0050] 2. Navigation for abnormal road conditions such as obstacles, potholes, and dead-end roads that affect driving in front of the vehicle: After the scanning radar 126 transmits the sonar signal in a scanning manner, the sonar signal has a strong echo in the direction of the vehicle's advance, that is, the echo signal change rate of the sonar signal on the flat road is not high, but when the sonar signal is irradiated to the obstacle in front, the echo of the obstacle is different from the echo signal on the flat road. After the differential echo is received by the scanning radar 126 and analyzed and calculated by an external computer, it can be accurately concluded that the echo signal is an obstacle detected at a certain distance in the direction of the vehicle's advance, and the distance of the obstacle from the vehicle is analyzed, and whether the obstacle will be encountered is calculated based on the vehicle's parameters.
