[0034] The first embodiment of the present invention relates to a cross-regional data transmission system, please refer to Figure 1 , including: a first server 1 for providing services in the first area and a second server 2 for providing services in the second area; wherein the first area and the second area are two areas with a boundary, such as two adjacent vehicle driving areas with a boundary. The cross-regional data transmission system is used to transmit vehicle-related data of an autonomous driving vehicle 3 between two adjacent areas, and there are different data supervision requirements for the data generated by the vehicle between the two adjacent areas; the following is an example of data generated in the second area being transmitted back to the first server in the first area. If the data generated in the first area needs to be transmitted back to the second area, the technical solution of this embodiment can also be adopted.

[0035] The first server 1 is configured in the first area to provide services for vehicles 3 traveling in the first area; the second server 2 is configured in the second area to provide services for vehicles 3 traveling in the second area, and the services referred to herein include but are not limited to: data processing services, data transmission services. The communication methods for providing services by the first server 1 and the second server 2 can be the same or different. For example, the first server 1 uses 5G private network communication in the first area, and the second server 2 uses another set of 5G private network communication in the second area; or, the first server 1 uses 5G private network communication in the first area, and the second server 2 uses Starlink communication in the second area.

[0036] When the vehicle 3 is traveling in the first area, the acquired vehicle-related data is sent to the first server 1 through the communication device on the vehicle 3 (for example, a 4G, 5G or other wireless communication device); when the vehicle 3 is traveling in the second area, the acquired vehicle-related data is sent to the second server 2 through the communication device on the vehicle (for example, a 4G, 5G or other wireless communication device). It should be noted that this embodiment is described by taking the vehicle 3 traveling in the second area as an example.

[0037] The second server 2 is used to receive vehicle-related data sent by a vehicle 3 located in the second area. The vehicle-related data includes but is not limited to the vehicle driving data during the vehicle driving process, the original data collected by the vehicle including image data and point cloud data, and the automatic driving assistance data sent by the roadside equipment during the vehicle driving process; it can even be the data sent by other vehicles driving in the surrounding area.

[0038] The vehicle driving data may include: vehicle driving speed, in-vehicle audio data, in-vehicle video data, data collected by in-vehicle sensors (such as temperature and humidity), vehicle acceleration data, vehicle braking data, etc. The original data collected by the vehicle includes: image data collected by an image sensor, such as external image data collected by a vehicle camera, and point cloud data collected by a vehicle radar sensor, the point cloud data including: road information, obstacle information, and traffic participant information. Roadside equipment may be installed on the road side of the first area and the second area. The roadside equipment is an automatic driving assistance device installed on both sides of the road, which includes at least one of the following: a radar sensor, a camera, a roadside communication device, an edge computing service device, and a satellite device. Different roadside equipment collects different data as automatic driving assistance data. The roadside equipment may sense traffic participant information and send it to passing vehicles as automatic driving assistance data, so that the vehicles can use these data to assist in automatic driving judgment, thereby improving the automatic driving safety of the vehicle 3.

[0039] The roadside equipment can be directly connected to the server providing services for the area through a wired or wireless connection and send the sensed data directly or after being processed by the edge computing server to the connected server. The server providing services for the area sends part or all of this data to a server in another adjacent area.

[0040] The second server 2 is further used to perform desensitization processing on the vehicle-related data based on a preset desensitization rule, and send the desensitized vehicle-related data to the first server 1 .

[0041] Among them, the preset desensitization rules are set based on the data transmission rules of the second area. For example, the second area restricts the transmission of image data such as videos and pictures. The desensitization rules are to perform fusion perception processing on the original data such as image data and point cloud data to obtain the perception results, and then send the perception results to the first server 1.

[0042] That is, the vehicle-related data of the vehicle 3 includes: image data, and the image data includes at least one of the following: road image data collected by the image sensor of the vehicle 3, and road image data collected by the roadside equipment; then:

[0043] The second server 2 is used to obtain perception result information of the image data with respect to the image data, and send the perception result information to the first server 1 .

[0044] For another example, if the second area restricts data outside the vehicle from being transmitted, the desensitization rule is to only allow vehicle driving data to be transmitted to the first area, and all other data is prohibited from being transmitted to the first area; for example, the vehicle-related data includes: vehicle driving data. The second server 2 is used to send the vehicle driving data to the first server 1 for the vehicle driving data.

[0045] It should be noted that the preset desensitization rules can include one or more rules, which can be used in combination without conflict:

[0046] For example, image data needs to be processed before it can be transmitted. The processing methods include but are not limited to: blurring or mosaicing people, road signs, buildings, etc. before transmission; or performing fusion perception processing on image data to obtain the perception result information of text before transmission; or directly prohibiting all image data related information from being transmitted;

[0047] For example, vehicle driving data does not need to be processed and can be transmitted directly.

[0048] In one embodiment, a background management system for autonomous driving is also configured in the first area. The background management system can be configured in the area where vehicle driving data is mainly stored and managed. The background management system can also be used to perform system updates on roadside equipment.

[0049] For the roadside devices in the first area, the first server may directly send each update file to the corresponding roadside device via wired or wireless means, so that the roadside device can complete the system update.

[0050] For the roadside equipment in the second area, the background management system is used to send the update file used to update the system or application software of the roadside equipment to the second server 2 through the first server 1, and the second server 2 completes the system or application software update of the roadside equipment in the second area based on the update file. After completing the system or application software update of the roadside equipment, the second server 2 sends a notification message indicating the completion of the update to the background management system of the local server 1.

[0051] In one example, the vehicle 3 includes a first communication system corresponding to the first server, and a second communication system corresponding to the second server; when the vehicle is in a first area, the first communication system is used to communicate with the first server 1; when the vehicle is in a second area, the second communication system is used to communicate with the second server 2.

[0052] For an example, see Figure 2 The cross-regional data transmission system further includes: a first positioning system 4 for providing positioning services in the first region and a second positioning system 5 for providing positioning services in the second region. The first positioning system 4 and the second positioning system 5 can be the common GPS global positioning system and Beidou positioning system, which can be selected according to the positioning systems available in each region.

[0053] At the boundary between the first area and the second area, the positioning coverage of the first positioning system 4 and the second positioning system 5 overlaps, and the overlapping area includes part of the first area and part of the second area, and the boundary between the first area and the second area.

[0054] The second server 2 is used to switch to the second positioning system 5 to locate the vehicle 3 after the vehicle enters the second area from the first area and is within the positioning coverage of the second positioning system 5. If the first position of the vehicle 3 located by the first positioning system 4 sent by the first server 1 matches the second position of the vehicle 3 located by the second positioning system 5, the second server 2 is used to send a notification message to the first server 1 indicating that the vehicle 3 is located by the second positioning system 5.

[0055] The first server 1 is used to switch the first positioning system 4 to locate the vehicle after the vehicle enters the first area from the second area and is within the positioning coverage of the first positioning system 4. If the third position of the vehicle 3 located by the second positioning system 5 sent by the second server 2 matches the fourth position of the vehicle 3 located by the first positioning system 4, the first server 1 is used to send a notification message to the second server 2 indicating that the vehicle 3 is located by the first positioning system 4.

[0056] For example, after the vehicle 3 passes the boundary of the first area and enters the second area from the first area, it enters the overlapping positioning area between the first positioning system 4 and the second positioning system 5. At this time, both the first positioning system 4 and the second positioning system 5 can locate the vehicle 3. The first positioning system 4 continuously sends the first position of the vehicle 3 to the first server 1, and the first server 1 sends the first position to the second server 2; the second positioning system 4 sends the second position of the located vehicle 3 to the second server 2, and the second server 2 compares the first position of the vehicle 3 with the second position. When the deviation between the two positions is less than the set deviation value, it is determined that positioning switching can be performed; the second server 2 sends a notification message to the first server 1 indicating that the positioning is performed by the second positioning system 5.

[0057] In some embodiments, when the first position sent by the first server 1 indicates that the vehicle 3 has arrived at the first preset area of ​​the second area, the second server 2 can control the second positioning system 5 to locate the vehicle 3, receive the second position sent by the second positioning system 5 as the position of the vehicle 3, and notify the first server 1 to control the first positioning system 4 to no longer locate the vehicle 3. Before the vehicle 3 arrives at the first preset area, the second server 2 receives the first position sent by the first server 1 as the position of the vehicle 3.

[0058] Vice versa, when vehicle 3 enters the first area from the second area, before entering the second preset area within the first area, the first server 1 receives the second position sent by the second server 2 as the position of vehicle 3. After vehicle 3 enters the second preset area, the first positioning system 4 is controlled to locate vehicle 3, the first position sent by the first positioning system 4 is received as the position of vehicle 3, and the second server 2 is notified to control the second positioning system 5 to no longer locate vehicle 3.

[0059] From the above, when the vehicle 3 travels across two areas, the switching of the positioning system can be successfully completed, the vehicle 3 can be seamlessly positioned, and the position of the vehicle 3 can be avoided from being lost.

[0060] The second embodiment of the present invention relates to a cross-regional data transmission method of this embodiment, which is applied to the cross-regional data transmission system in the first embodiment; the cross-regional data transmission method includes: a second server receives vehicle-related data sent by a vehicle located in a second area, and desensitizes the vehicle-related data based on a preset desensitization rule; the second server desensitizes the vehicle-related data based on the preset desensitization rule, and sends the desensitized vehicle-related data to the first server.

The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and the technical effects that can be achieved in the first embodiment can also be achieved in this embodiment. In order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the first embodiment.
