[0018] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the concept or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary in nature and not restrictive.

[0019] To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the related technologies of the embodiments of the present application. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0020] Vehicle-to-Cloud communication refers to the technology of data exchange and communication between vehicles and cloud servers through wireless networks. It is an important part of the concept of Internet of Vehicles (IoV). Through vehicle-to-cloud communication, vehicles can conduct two-way data transmission with the cloud, thereby realizing a series of intelligent and networked functions. The main functions of vehicle-to-cloud communication include: 1. Data collection and analysis, including vehicle data upload (sensors and systems in the vehicle (such as GPS, speed sensors, engine control units, etc.) can continuously collect vehicle operation data and upload this data to the cloud server through wireless networks), cloud analysis (the cloud server stores, processes and analyzes the uploaded data. This can help manufacturers, service providers and car owners understand the operating status of the vehicle, detect potential problems, and perform preventive maintenance); 2. Navigation and real-time traffic information, including: real-time navigation (by connecting to the cloud map service, the vehicle can obtain the latest map information and real-time traffic conditions, thereby providing more accurate navigation services), road condition reminders (the vehicle can receive cloud-based Traffic condition updates, such as traffic jams, road construction, accidents and other information, to help drivers plan their routes reasonably); 3. Remote monitoring and control (owners can remotely monitor the status of the vehicle through devices such as smartphones, and view information such as vehicle location, fuel level, battery level, tire pressure, etc. Certain functions of the vehicle can also be remotely controlled, such as remotely starting the engine, closing the door, turning on the air conditioner, etc. 5. Autonomous driving vehicles and fleet management, including autonomous driving data processing (autonomous driving systems need to process massive amounts of environmental data, and these data can be quickly uploaded and processed through vehicle-to-cloud communication, which improves the safety and accuracy of autonomous driving) and fleet management (monitoring and management of the entire fleet becomes extremely simple, and real-time vehicle location and operating data are clear at a glance).

[0021] The main application scenarios of vehicle-cloud communication include autonomous driving vehicles in long-distance freight logistics fleets, urban public transportation fleets, high-speed train fleets, etc.

[0022] However, there are currently two main types of vehicle-cloud communication: Method 1: Use a single communication module and a single operator's communication card to connect to the cloud server; Method 2: Use a single communication module and switch between different operators through two communication cards. Use a single communication module and a single operator's communication card to connect to the cloud server. Method 1 is the current mainstream solution, with low cost and simple maintenance. The risk is that the connection with the cloud server will be lost on sections that are not covered by the communication operator's network. Since current autonomous driving generally tends to operate on urban roads or high-speed routes, the network coverage is good, and most autonomous driving companies have not encountered the network disconnection problem caused by incomplete network coverage. Method 2 is an improved solution to Method 1. 5G communication modules generally support dual cards. When one network is disconnected, another communication card can be used to connect to the network, which makes up for the network disconnection problem caused by a single network. This solution is equivalent to supporting the networks of two operators, and the networks of the other two operators cannot be accessed.

[0023] In view of the above technical problems, the technical solution of the present application and how the technical solution of the present application solves the above technical problems are described in detail with specific embodiments below. The several specific embodiments listed can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment provides a vehicle-to-cloud communication system, such as Figure 1 The figure shows a structural block diagram of a vehicle-to-cloud communication system according to an embodiment of the present application, including:

[0025] Multiple mobile communication modules (for example, mobile communication module 11, mobile communication module 12) are used to communicate with cloud servers deployed in a cloud computing cluster via mobile communication links, wherein each mobile communication module is provided with a communication card, and the combination of communication cards in the multiple mobile communication modules supports a communication network of at least one communication operator.

[0026] It should be noted that the number of communication cards (i.e., SIM cards) provided in the mobile communication module in the embodiment of the present application is not limited, as long as the combination of communication cards in multiple mobile communication modules can support at least one communication network of a communication operator in a specific scenario (for example, a weak network scenario). In addition, it should be noted that the above-mentioned communication card can support reduced use under the same operator network. For example, assuming that the operator network is mobile, then in the embodiment of the present application, the above-mentioned communication card can be switched from 5G to 4G, or from 4G to 3G, etc. Regarding communication operators, it can be four operators a, b, c, and d under the 5G network, and three operators a, b, and c under the 4G network. Of course, more operator networks can also be included in the embodiment of the present application. Here, the number of operator networks and the type of operators are not specifically limited.

[0027] In addition, it should be noted that the cloud server deployed in the above cloud computing cluster may include one or more. Here, there is no limitation on the number of cloud servers deployed in the cloud computing cluster. The cloud servers deployed in the above cloud computing cluster provide powerful data storage, processing, analysis and computing capabilities. Through the combination with edge computing, the cloud servers not only support the real-time decision-making and environmental perception of autonomous driving vehicles, but also provide strong support for the training, optimization and deployment of machine learning models. In addition, the cloud server also plays an important role in high-precision map management, network communication, security protection and system monitoring, which improves the reliability and intelligence level of the autonomous driving system as a whole.

[0028] The satellite communication module 13 is used to respond to the satellite communication command initiated when the multiple mobile communication modules cannot establish communication with the cloud server, and establish a connection with the cloud server through a communication satellite to achieve communication between the formation of autonomous driving vehicles and the cloud server.

[0029] Optionally, in an embodiment of the present application, the method for determining whether the communication between the mobile communication module and the cloud server is normal may include but is not limited to: Method 1, network connection detection. The status of the network connection is detected by regularly sending Ping requests to the cloud server. If no server response is received within the specified time, there may be a communication failure. Method 2, signal strength and quality detection. The quality of the communication link is determined by reading its own signal strength indicator (Received Signal Strength Indicator, RSSI) value. An RSSI below a specific threshold may indicate a poor signal, thereby affecting the establishment of communication. Method 3, analyzing the status and error log of the mobile communication module. The mobile communication module usually has a self-test function, which can analyze the abnormal status of its own hardware and software reported by the mobile communication module. For example, a SIM card reading error or a modem failure. Alternatively, analyze the error log of the mobile communication module to determine whether there is a hardware failure, configuration error or other anomaly. Method 4, data analysis and machine learning. By analyzing historical communication data and fault records, using big data and machine learning algorithms to predict and diagnose communication faults, the machine learning model can identify abnormal behavior in a timely manner based on historical patterns. The specific process may include: 1. Data collection and preprocessing. Data collection includes communication logs and fault records, and data preprocessing includes data cleaning, data formatting, segmentation, etc. 2. Feature extraction and selection. Extract features useful for prediction and diagnosis from the original data, such as the average and standard deviation of signal strength, the mean and peak of delay, packet loss rate, frequency distribution, etc., and use correlation analysis and feature importance evaluation to select the most effective features for fault prediction to improve model performance and reduce computational overhead. 3. Model training and verification. Select one or more machine learning algorithms, train the models separately, and optimize the hyperparameters of the models through grid search or random search to improve model performance. Use indicators such as accuracy, recall rate, and F1 score to comprehensively evaluate the prediction performance of the model, and use verification methods to further verify the generalization ability of the model. 4. Prediction and diagnosis. Extract the corresponding features in the real-time monitoring data, input the features into the trained model, predict the communication status in real time, and identify potential abnormal behaviors. For the identified abnormal situations, perform fault diagnosis to determine the specific fault type and impact range.

[0030] The above-mentioned vehicle-cloud communication system may also include a controller, which includes but is not limited to: a selection module, which is used to give priority to the mobile communication link for data communication when both the mobile communication link and the satellite communication link are available; a sending module, which is used to send satellite communication instructions to the satellite communication module when the mobile communication links are all in an interrupted state, so as to communicate with the cloud server through the satellite communication link; a monitoring module, which is used to monitor in real time whether there is an available link in the mobile communication link during the process of communicating with the cloud server through the satellite communication link, and a switching module, which is used to switch the satellite communication link to the available link when there is an available link in the mobile communication link, etc. The above-mentioned controller is equivalent to a centralized control and management platform, which can coordinate and optimize the communication status of multiple mobile communication modules and satellite communication modules, thereby improving the overall performance and reliability of the formation autonomous driving vehicles.

[0031] pass Figure 1 The system shown has multiple mobile communication modules for communicating with a cloud server deployed in a cloud computing cluster via a mobile communication link, wherein each mobile communication module is provided with a communication card, and the combination of communication cards in the multiple mobile communication modules supports a communication network of at least one communication operator; a satellite communication module is used to respond to a satellite communication instruction initiated when the multiple mobile communication modules cannot establish communication with the cloud server, and establish a connection with the cloud server via a communication satellite to achieve communication between the formation autonomous driving vehicles and the cloud server. That is to say, the embodiment of the present application sets up multiple mobile communication modules, and the communication card combination in the multiple mobile communication modules supports the communication network of at least one communication operator, so as to ensure that the convoy autonomous driving vehicles can connect to possible nearby mobile communication base stations and maintain a stable connection with the cloud server through the mobile communication base stations. In addition, a satellite communication module is set on the convoy autonomous driving vehicles, so that on sections of roads not covered by mobile communication base stations or sections where mobile communication cannot establish a connection, it can maintain a connection with the cloud server through satellite communication, thereby solving the technical problem of using a single communication module in the related technology, in which the single communication module is set up with one communication card or two communication cards to switch the communication networks of different operators, resulting in the loss of connection with the cloud server on sections that are not covered by the communication operator network and sections where mobile communication cannot establish a connection, thereby achieving the technical effect of ensuring the stability and reliability of vehicle-cloud communication.

[0032] In a possible implementation, the communication link between the formation autonomous driving vehicle and the cloud server includes at least a mobile communication link and / or a satellite communication link, and the above-mentioned vehicle-cloud communication system further includes: a selection module for selecting the mobile communication link for data communication when both the mobile communication link and the satellite communication link are available. That is, in the embodiment of the present application, when both the mobile communication link and the satellite communication link are available, the mobile communication link is preferred for data communication, further reducing the communication cost.

[0033] It should be noted that the mobile communication link may be a communication link formed by connecting a mobile communication module to a base station, a base station to a cloud server, and the satellite communication link may be a communication link formed by connecting a satellite communication module to a communication satellite, a communication satellite to a satellite communication data transfer station, and a satellite communication data transfer station to a cloud service. Optionally, at least one communication card may be provided in the satellite communication module, for example, a communication card of one of the four operators a, b, c, and d.

[0034] In the case where the communication card supports downgraded use under the same operator network, the selection module includes: a processing submodule for repeatedly performing the following steps until the mobile communication links are all in an interrupted state: selecting the communication link of the initial network as the initial communication link, wherein the initial network is a network with a higher level; using the initial communication link for data communication, and in the case where the initial communication link is completely interrupted, selecting the communication link of the target network, and using the communication link of the target network for data communication, wherein the level of the target network is lower than that of the initial network; setting the target network to the initial network. And, the selection module may also include: a switching submodule for switching the current communication link to the available communication link in the initial communication link when the initial communication link is partially interrupted. It should be noted that in the embodiment of the present application, the network with a higher level may be 5G, the network with a lower level may be 4G, and so on, and the lower level is 3G / 2G. That is, in the embodiment of the present application, the mobile communication module 11 or the mobile communication module 12 preferentially uses the 5G network connection, and switches to another link when a link interruption is detected. If another link is also interrupted, it will be downgraded to a 4G mode connection. If the 4G mode fails to connect, it will continue to downgrade to 3G / 2G mode to try to connect. , so that you can make good use of the network coverage of all operators.

[0035] Optionally, the vehicle-cloud communication system further includes: a sending module, which is used to send the satellite communication instruction to the satellite communication module when the mobile communication links are all in an interrupted state, so as to communicate with the cloud server through the satellite communication link. That is, when the above-mentioned multiple mobile communication modules (for example, mobile communication module 11 or mobile communication module 12) are unable to establish a connection with the cloud server, a satellite communication instruction can be sent to the satellite communication module to maintain a connection with the server using satellite communication to ensure the stability of the connection between the formation autonomous driving vehicle and the cloud server.

[0036] During satellite communication, the above-mentioned vehicle-cloud communication system also includes: a monitoring module, which is used to monitor in real time whether there is an available link in the mobile communication link during the communication with the cloud server through the satellite communication link; a switching module, which is used to switch the satellite communication link to the available link when there is an available link in the mobile communication link. That is, during satellite communication, the formation of autonomous driving vehicles may enter the mobile communication network coverage area at any time during the driving process. Then, in the embodiment of the present application, multiple mobile communication modules (for example, mobile communication module 11 or mobile communication module 12) on the formation of autonomous driving vehicles will conduct real-time connection attempts to the 5G / 4G / 3G / 2G network. As long as there is a mobile communication link that can connect to the cloud server, data will be sent and received through the mobile communication link to reduce satellite communication costs.

[0037] The embodiments of the present application are described below with reference to specific examples.

[0038] like Figure 2 As shown, two mobile communication modules (mobile communication module A and mobile communication module B) and a satellite communication module are installed on the autonomous driving vehicle. Mobile communication module A is installed with two communication cards, a card and b card, which can be connected to base station a through link 1 or base station b through link 2, and connected to the cloud server through the base station. Mobile communication module B is installed with two communication cards, c card and d card, which can be connected to base station c through link 3 or base station d through link 4, and connected to the cloud server through the base station. The satellite communication module is installed with b card, which can be connected to the satellite through link 5 and connected to the cloud server through the ground satellite data transfer station.

[0039] During the driving process of the autonomous driving vehicle, mobile communication module A, mobile communication module B and satellite communication module are all connected to the cloud server, so that a total of three links are established, link 1 or 2, link 3 or 4, link 5. Only the connection is established, and no traffic fee is charged when there is no communication traffic. When all three links are normal, the mobile communication link is preferred for data communication (mobile communication cost is low). Mobile communication module A or B gives priority to using 5G network connection, and switches to another link when a link interruption is detected. If the other link is also interrupted, it will be downgraded to 4G mode to try to connect. If it cannot be connected in 4G, it will continue to downgrade to 3G / 2G mode to try to connect. When all four mobile links cannot be established, satellite communication is used to maintain connection with the server. During satellite communication, mobile communication module A or mobile communication module B will still attempt to connect to the 5G / 4G / 3G / 2G network. As long as there is a mobile communication link that can connect to the server, data is sent and received through the mobile communication link to reduce satellite communication costs. That is, in this example, in order to support the networks of all operators, two mobile communication modules supporting dual SIM cards are set up, and four communication cards of different operators are set up to make good use of the network coverage of all operators.

[0040] In summary, the embodiment of the present application installs communication cards of all operators on the autonomous driving vehicle, and installs at least two mobile communication modules to ensure that the formation autonomous driving vehicle can connect to all possible nearby mobile communication base stations and maintain a stable connection with the cloud server through the mobile communication base station. A satellite communication module is installed on the autonomous driving vehicle, and it can maintain a connection with the cloud server through satellite communication on sections of the road that are not covered by mobile communication base stations or sections where mobile communication cannot establish a connection.

[0043] S302 is used to replace the above S301, and the convoy autonomous driving vehicles use the above vehicle-cloud communication system to connect to the communication satellite to communicate with the cloud server deployed in the cloud computing cluster through the satellite communication data transfer station.

[0044] Through the above S301 or S302, multiple mobile communication modules are used to communicate with the cloud server deployed in the cloud computing cluster through mobile communication links, wherein each mobile communication module is provided with a communication card, and the combination of communication cards in the multiple mobile communication modules supports the communication network of at least one communication operator; the satellite communication module is used to respond to the satellite communication instruction initiated when the multiple mobile communication modules cannot establish communication with the cloud server, and establish a connection with the cloud server through a communication satellite to realize communication between the formation autonomous driving vehicles and the cloud server. That is to say, the embodiment of the present application sets up multiple mobile communication modules, and the communication card combination in the multiple mobile communication modules supports the communication network of at least one communication operator, so as to ensure that the convoy autonomous driving vehicles can connect to possible nearby mobile communication base stations and maintain a stable connection with the cloud server through the mobile communication base stations. In addition, a satellite communication module is set on the convoy autonomous driving vehicles, so that on sections of roads not covered by mobile communication base stations or sections where mobile communication cannot establish a connection, it can maintain a connection with the cloud server through satellite communication, thereby solving the technical problem of using a single communication module in the related technology, in which the single communication module is set up with one communication card or two communication cards to switch the communication networks of different operators, resulting in the loss of connection with the cloud server on sections that are not covered by the communication operator network and sections where mobile communication cannot establish a connection, thereby achieving the technical effect of ensuring the stability and reliability of vehicle-cloud communication.

[0047] The first communication module 42 is replaced by a second communication module, which is used to connect to a communication satellite using the vehicle-cloud communication system to communicate with a cloud server deployed in a cloud computing cluster through a satellite communication data transfer station.

[0048] pass Figure 4The device shown comprises multiple mobile communication modules for communicating with a cloud server deployed in a cloud computing cluster via a mobile communication link, wherein each mobile communication module is provided with a communication card, and the combination of the communication cards in the multiple mobile communication modules supports a communication network of at least one communication operator; a satellite communication module for responding to a satellite communication instruction initiated when the multiple mobile communication modules are unable to establish communication with the cloud server, and establishing a connection with the cloud server via a communication satellite to achieve communication between the formation autonomous driving vehicles and the cloud server. That is to say, the embodiment of the present application sets up multiple mobile communication modules, and the communication card combination in the multiple mobile communication modules supports the communication network of at least one communication operator, so as to ensure that the convoy autonomous driving vehicles can connect to possible nearby mobile communication base stations and maintain a stable connection with the cloud server through the mobile communication base stations. In addition, a satellite communication module is set on the convoy autonomous driving vehicles, so that on sections of roads not covered by mobile communication base stations or sections where mobile communication cannot establish a connection, it can maintain a connection with the cloud server through satellite communication, thereby solving the technical problem of using a single communication module in the related technology, in which the single communication module is set up with one communication card or two communication cards to switch the communication networks of different operators, resulting in the loss of connection with the cloud server on sections that are not covered by the communication operator network and sections where mobile communication cannot establish a connection, thereby achieving the technical effect of ensuring the stability and reliability of vehicle-cloud communication.
