Description

Technical Field

[0001] The present invention relates to a navigator, and in particular to a vehicle-mounted navigator with monitoring and adjustment functions and a method for using the same. Background Art

[0002] In the field of vehicle navigation, there are many forms of navigation, such as driving route information, traffic congestion information ahead, etc. However, most of the vehicle-mounted navigation methods of such navigators passively receive navigation signals, and the navigation information is single. The driver can only drive relying on 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 state. Moreover, when such navigators are used under complex road conditions, there is no more road condition navigation information. For example, when the vehicle is driving in the wild, an engineering vehicle driving on an unpaved road surface, or when performing field exploration, rescue and other conditions with complex road surfaces, such navigators cannot provide effective road condition navigation. At present, for vehicles using lidar for assisted automatic driving, more often the road condition information is directly applied to the program algorithm and the vehicle is directly operated through the program algorithm, which cannot be displayed on the navigator for the driver to understand the road conditions ahead and make timely adjustments. Moreover, such navigators are more commonly used in vehicles driving in the city, with great potential safety hazards. And using lidar to identify road condition information in the city is likely to affect electronic devices in the city.

The follower sleeve 121 is respectively fixedly connected to the outside of the follower shaft 101. The right sides of the follower sleeves 121 are all annular structures. The inner sides of the annular structures of the follower sleeves 121 are all structures with sealing rings. The sealing ring structures on the inner sides of the follower sleeves 121 are respectively in contact with the front and rear sides of the connecting arm 7 to prevent dust and mud from entering the follower sleeves 121 and causing blockages. The sealing ring structures of the follower sleeves 121 respectively surround the second bearing 100. The left sides of the inner parts of the follower sleeves 121 are all rotatably connected to the rotating shaft 122. The rotating shaft 122 is vertically arranged. The left sides of the inner parts of the follower sleeves 121 are all fixedly connected to the driving motor 123. The driving motor 123 is controlled by a servo system.

The installation cabins 125 are respectively installed at both ends of the rotating shaft 122 through their U-shaped structures. Scanning radars 126 are installed inside the outer positions of the left side surfaces of the installation cabins 125.

[0045] As Figure 11 As shown in the figure, the navigation control part 02 includes a controller 131, a radar display 132, a voice broadcaster 133, and a code display 134. The controller 131 is installed on the vehicle's in-vehicle console. The controller 131 is used to set parameters, receive and process data from the road condition monitoring part 01, operate and set operation parameters and postures, control the vehicle state, etc. There are multiple groups of radar displays 132 on the panel of the controller 131.

The code displays 134 are used to display the codes converted from the road condition information calculated according to the program settings, the data of the scanning radar 126, and the vehicle driving data.

[0046] The specific installation method of the navigation control part 02 of the in-vehicle navigator with monitoring and adjustment functions: The navigation control part 02 can be installed on the vehicle's central console through the controller 131, and the control circuit and signal lines of the controller 131 are connected to the road condition monitoring part 01. The control circuit, signal lines, and power supply circuit of the controller 131 are connected to the vehicle power supply, in-vehicle computer, and external computer.

[0047] I. The specific attitude adjustment method of the road condition monitoring part 01 of the in-vehicle navigator with monitoring and adjustment functions:

[0048] 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, and the connecting arm 7 will raise the height of the monitoring device 12, so that the monitoring device 12 can have a higher road condition monitoring view. While the connecting arm 7 is rotating, the follower rod 103 will be limited and pulled by the connecting rod 93, the fixed shaft 91, the first crankshaft section 92, and the fine adjustment device 11, so that the follower rod 103 drives the second crankshaft section 102 to maintain the position through the follower shaft 101, and the follower shaft 101 will rotate on its own, so that the follower shaft 101 drives the follower sleeve 121 and the installation cabin 125 to maintain the leftward facing angle, so that the monitoring device 12 can maintain the working state of scanning and monitoring the road conditions in front of the vehicle under the rotation and lifting action of the connecting arm 7.

[0049] 2. It is also possible to control the operation of the electric push rod 111, so that the telescopic member of the electric push rod 111 drives the follower rod 103 to move through the interconnection shaft 112, and the follower rod 103 drives the follower shaft 101 to rotate independently through the second crankshaft section 102, so as to control the precise orientation angle of the monitoring device 12, so that the monitoring device 12 can scan and monitor the road conditions at a certain distance in front of the vehicle. In this way, when the vehicle is driving at a low speed in complex road conditions, more accurate road condition scanning and monitoring information can be obtained.

[0050] 3. When the vehicle is driving in a jungle or an area with height restrictions, the scanning radar 126 will also identify whether the monitoring device 12 will hit an obstacle of 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 the height to avoid hitting, realizing the adaptive adjustment of the road condition monitoring part 01.

[0051] 4. When the vehicle needs to drive at a low speed in complex road conditions, traffic jams and other situations, the driving device 8 can be controlled to drive the connecting arm 7 to make the monitoring device 12 in the highest position state, so that the monitoring device 12 has a higher monitoring azimuth and thus a farther monitoring view.

[0052] 5. When the vehicle is on a paved road with good road conditions, the vehicle can travel at high speed. At this time, the drive device 8 can be controlled to drive the connecting arm 7 to make the monitoring device 12 in the lowest position, reducing the windward cross-sectional area of the road condition monitoring part 01 and the wind resistance of the road condition monitoring part 01 when the vehicle is traveling at high speed. At this time, the unfolded monitoring device 12 can continue to be used for road condition monitoring; if there is no need for the monitoring device 12 to monitor and navigate the road conditions, the drive motor 123 can be controlled to operate, so that the drive 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, making the installation cabin 125 rotate to contact the front and rear sides of the connecting arm 7, thereby reducing the windward area of the installation cabin 125, and further reducing the windward cross-sectional area of the road condition monitoring part 01 and further reducing the wind resistance when the vehicle is traveling.

[0053] II. The method for monitoring road conditions and road condition navigation of the in-vehicle navigator with monitoring and adjustment functions:

[0054] Start the scanning radar 126. The scanning radar 126 will emit sonar signals in a scanning manner in the forward direction of the vehicle. After the sonar signals irradiate the road surface in front of the vehicle, echoes will be generated. The scanning radar 126 receives the sonar echoes. Different road conditions will generate different forms of echoes, that is, there are differences between the echo signals generated by different road conditions. The different echoes received by the scanning radar 126 will be analyzed and calculated through the program of an external computer, and the echo signals will be converted into other signals to navigate the driver about the road conditions ahead. For example, the position signals that can be displayed at the radar display 132, the sound signals that need to act on the voice broadcaster 133 to inform the driver after echo analysis, and the code signals that need to be displayed on the code display 134 with different codes to prompt the driver after echo analysis; according to the working process of the above scanning radar 126, through the differences in echo signals and through data comparison, analysis and calculation of an external computer, the differences in echo signals can be output as different other signals and act on different navigation guiding components, that is, the different signals output are converted into different navigation methods.

[0055] III. An example of the method for monitoring road conditions and road condition navigation of the in-vehicle navigator with monitoring and adjustment functions:

[0056] 1. Road condition navigation for the road surface in front of the vehicle: After the scanning radar 126 emits sonar signals in a scanning manner, the sonar signals irradiate the road surface in the forward direction of the vehicle with relatively different road surface echo signals. That is, the differences in the echo signals reflected from different road surfaces such as paved roads, unpaved roads, waterlogged roads, sandy roads, and sandy ground surfaces when the sonar signals irradiate them. The differential echo signals are converted into signals recognizable by an external computer after being received by the scanning radar 126. The external computer can accurately obtain that the echo signal is a road surface condition that requires different driving methods at a certain distance in the forward direction of the vehicle through big data comparison and analysis calculations. That is, it can be monitored by the scanning radar 126 that there is an unpaved road or other road surfaces affecting driving in front of the vehicle. After analyzing the content represented by the signal, the external computer will convert and output the signal to the voice broadcaster 133 or the code display 134 through a program, informing the driver of the difference in the road conditions ahead in a specific voice broadcast and specific codes, or informing the driver of what kind of road surface condition lies ahead. In addition, the driving speed of the vehicle can be controlled by the controller 131, the external computer, and the in-vehicle computer when the scanning radar 126 recognizes different road surfaces. That is, when the scanning radar 126 recognizes an unpaved road, the controller 131, the external computer, and the in-vehicle computer will control the driving speed of the vehicle to decrease according to the program settings to achieve road condition monitoring navigation and vehicle speed adjustment.

[0057] 2. Navigation for road conditions with abnormal situations on the road surface such as obstacles affecting driving, potholes, dead-end roads, etc. in front of the vehicle: After the scanning radar 126 emits sonar signals in a scanning manner, if there is a strong echo when the sonar signal irradiates in the vehicle's forward direction, that is, the change rate of the echo signal when the sonar signal irradiates on a flat road surface is not high. However, when the sonar signal irradiates on an obstacle in front, there is a difference between the echo of the obstacle and the echo signal on the flat road surface. After the differential echo is received by the scanning radar 126 and analyzed and calculated by an external computer, it can accurately obtain that the echo signal indicates the presence of an obstacle at a certain distance in the vehicle's forward direction, analyze the distance between the obstacle and the vehicle, and calculate whether the obstacle will affect the vehicle's passage and other impacts of the obstacle on the vehicle's driving state based on the vehicle's parameters. This signal will be output by the external computer through a program to the radar display 132 for position display and announced through the voice broadcaster 133, and navigation will be carried out through specific voice announcements and position displays on the radar display 132 so that the driver can understand the information about the obstacle ahead. In addition, when the scanning radar 126 recognizes that there is a potential safety hazard for the vehicle's driving due to an obstacle ahead, that is, if the scanning radar 126 recognizes that an obstacle or pothole ahead will affect the vehicle's driving safety, the controller 131, external computer, and in-vehicle computer will control the vehicle's driving speed to decrease according to the program settings.
