[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] The collection, storage, use, processing, transmission, provision, and disclosure of financial data or user data involved in the technical solution of this application all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0057] Currently, the performance of vehicle infotainment systems and applications within them when using the vehicle network presents the following problems for different users: (1) For administrators responsible for optimizing vehicle infotainment systems, the problems include: when many applications are running, the vehicle infotainment system will lag and the network access speed will slow down, thus affecting the user experience, especially the network usage of important applications cannot be guaranteed; among them, important applications are those that users use frequently and that are closely related to users, including but not limited to map applications that control navigation sources in the vehicle infotainment system and music applications that control music sources in the vehicle infotainment system; after the vehicle is sold, it is impossible to analyze the network operation status of the vehicle infotainment system in different driving environments in real time, and it is impossible to evaluate and dynamically optimize the network operation quality of the vehicle infotainment system; when the vehicle infotainment system experiences abnormal network performance, there is a lack of corresponding emergency handling mechanisms; and there is a lack of effective supervision for some illegal applications that illegally occupy the network traffic resources of the vehicle infotainment system. (2) For application developers, the problems include: after the vehicle is released, it is impossible to analyze the network operation status of the application in different driving environments and to track the network performance problems of the application; when the application runs in a network performance-related abnormal situation, there is no corresponding handling mechanism; and there is no official way to solve the optimization problem of the application using the vehicle network.

[0058] To address the aforementioned issues, this application provides a vehicle network control method, apparatus, device, and storage medium. By acquiring target applications that are running and have network access permissions, and adjusting the network bandwidth used by these applications according to vehicle network control policies, it ensures network bandwidth for critical applications, as well as for applications running in the foreground and background, while restricting network bandwidth used by unauthorized applications. Furthermore, the application whitelist within the vehicle network control policy provides application developers with official vehicle network optimization methods. Therefore, it enables more rational use of the vehicle network, improves network access speed for the vehicle's infotainment system, and ultimately enhances the user experience.

[0059] The following section provides examples illustrating the application scenarios of the solution provided in this application.

[0060] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. For example... Figure 1 As shown, in this application scenario, server 101 is configured with an in-vehicle network control policy. After the vehicle's infotainment system 102 starts up, it obtains the in-vehicle network control policy from server 101. Based on the in-vehicle network control policy, it adjusts the network bandwidth used by applications running in the infotainment system that have network access permissions, so that the applications in the infotainment system can use the in-vehicle network according to the adjusted network bandwidth.

[0061] It should be noted that, Figure 1This is merely a schematic diagram illustrating one application scenario provided by an embodiment of this application. This embodiment does not necessarily represent... Figure 1 The included equipment is not limited, nor is it restricted. Figure 1 The positional relationships between devices are defined. For example, in Figure 1 The application scenario shown may also include a data storage device, which may be an external storage device relative to server 101 or an internal storage device integrated into server 101.

[0062] The technical solution of this application will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0063] Figure 2 A flowchart illustrating an embodiment of the vehicle network control method provided in this application, applied to the vehicle's infotainment system. For example... Figure 2 As shown, the method in this application embodiment includes:

[0064] S201. Obtain the target application that is running and has network access permissions.

[0065] For example, after the vehicle's infotainment system starts up, it can automatically scan for target applications that are running and have network access permissions, and record the running information of these applications. These target applications with network access permissions are those that can use the vehicle's network. The running information includes, but is not limited to, whether the application is running, the network bandwidth it uses, and whether it is running in the foreground or background. It can be understood that for applications that are not running but have network access permissions, no network bandwidth adjustment is required.

[0066] S202. Based on the application whitelist in the vehicle network control policy, determine the application type of the target application. The application type includes whitelisted applications and non-whitelisted applications. Whitelisted applications include important applications and ordinary applications.

[0067] It is understood that applications included in the application whitelist have network access permissions, while applications not included in the application whitelist do not. For example, when the vehicle system starts up, the in-vehicle network control policy is obtained from the server communicating with the vehicle system. This policy includes the application whitelist. For details on how to obtain the in-vehicle network control policy, please refer to subsequent embodiments; it will not be repeated here. In this step, after obtaining the target application that is running and has network access permissions, the target application can be compared with applications in the application whitelist to determine the application type of the target application. Specifically, if the target application is included in the application whitelist, its application type is a whitelisted application; if it is not included in the application whitelist, its application type is a non-whitelisted application, which can also be understood as an illegal application; if the target application is included in the application whitelist and is an important application within the whitelist, its application type is an important application; if it is included in the application whitelist but is not an important application within the whitelist, its application type is a normal application. Important applications include, but are not limited to, map applications that control navigation sources in the vehicle infotainment system and music applications that control music sources in the vehicle infotainment system.

[0068] S203. Adjust the network bandwidth used by the target application according to the application type of the target application. Among them, the network bandwidth of important applications is not limited.

[0069] In this step, after determining the application type of the target application, the network bandwidth used by the target application can be adjusted according to its application type. Specifically, priority should be given to ensuring that important applications have their network bandwidth used preferentially; that is, no restrictions should be placed on the network bandwidth of important applications. For example, if an important application is a map application, when the map application is in navigation mode, its network bandwidth usage should be guaranteed regardless of whether it is running in the foreground or background. Similarly, if an important application is a music application, when the music application is playing music, its network bandwidth usage should be guaranteed regardless of whether it is running in the foreground or background.

[0070] Further, optionally, the vehicular network control strategy includes a first downlink network bandwidth, a first uplink network bandwidth, a second downlink network bandwidth, and a second uplink network bandwidth. Adjusting the network bandwidth used by the target application based on its application type may include: if the target application is a normal application and is running in the foreground, adjusting both the downlink and uplink network bandwidth used by the target application to the first downlink network bandwidth; if the target application is a normal application and is running in the background, adjusting both the downlink and uplink network bandwidth used by the target application to the second downlink network bandwidth; where the first downlink network bandwidth is greater than the second downlink network bandwidth, and the first uplink network bandwidth is greater than the second uplink network bandwidth; and if the target application is a non-whitelisted application, adjusting the network bandwidth used by the target application to 0.

[0071] It's understandable that network bandwidth adjustments are needed for regular applications. For applications running in the foreground, higher network bandwidth is required than for those running in the background to prioritize user experience. For example, if the first downlink and first uplink network bandwidth are both 0.8 Mbps, and the second downlink and second uplink network bandwidth are both 3 KB / s, then the uplink and downlink network bandwidth for foreground applications can be adjusted to 0.8 Mbps, and the uplink and downlink network bandwidth for background applications can be adjusted to 3 KB / s. The downlink and uplink network bandwidth for foreground applications should not exceed 1 Mbps, and the downlink network bandwidth for background applications should not exceed 7 KB / s and the uplink network bandwidth should not exceed 3.5 KB / s. If the target application is not a whitelisted application, then the network bandwidth used by the target application should be adjusted to 0, effectively restricting network bandwidth usage for non-whitelisted applications, and monitoring of non-whitelisted applications will be implemented. It is understandable that the vehicle-mounted system adjusts the network bandwidth used by target applications according to the vehicle network control policy, which can effectively guarantee the network bandwidth used by whitelisted applications, especially important applications.

[0072] Optionally, the vehicle-mounted system can adjust the network bandwidth used by the target application by calling an interface provided by the system and executing an instruction containing the application package name, process ID, uplink network bandwidth, downlink network bandwidth, and whether the application is legitimate. If the target application is on the whitelist, it is considered legitimate; if it is not on the whitelist, it is considered illegitimate, and the network bandwidth used by an illegitimate application is 0.

[0073] After adjusting the network bandwidth used by the target application, the target application uses the in-vehicle network according to the adjusted network bandwidth.

[0074] The vehicle network control method provided in this application determines the application type of a target application that is running and has network access permissions based on the application whitelist in the vehicle network control policy. Specifically, it determines whether the target application is an important application, a normal application, or a non-whitelisted application. Based on the application type, the method adjusts the network bandwidth used by the target application. Important applications have unlimited network bandwidth, ensuring priority access to network bandwidth for important applications. Adjusting the network bandwidth used by normal applications and non-whitelisted applications allows for more efficient use of the vehicle network, improving network access speed for the vehicle system and thus enhancing the user experience.

[0075] In some embodiments, considering that the running state of an application may change, and that the vehicle network control policy needs to be re-executed for applications whose running state changes, the acquisition of a target application that is running and has network access permissions may optionally include: if it is detected that an application has switched from running in the foreground to running in the background, or if it is detected that an application has switched from running in the background to running in the foreground, then the application is determined to be the target application; if it is detected that an application with network access permissions has started, then the started application is determined to be the target application.

[0076] It is understandable that applications whose operating status changes can include important applications, ordinary applications, and non-whitelisted applications. Therefore, the applications whose operating status has changed need to be targeted, and the vehicle network control policy needs to be re-executed. Specifically, based on the application whitelist in the vehicle network control policy, the application type of the target application is determined. If the target application type is an important application, no network bandwidth restrictions are imposed; if the target application type is an ordinary application or a non-whitelisted application, the network bandwidth used is adjusted.

[0077] Figure 3 A flowchart of a vehicle network control method provided in another embodiment of this application is shown, applied to a server. For example... Figure 3 As shown, the method in this application embodiment includes:

[0078] S301. Receive configuration completion instruction. The configuration completion instruction includes vehicle network control policy and execution switch corresponding to vehicle network control policy. Vehicle network control policy includes application whitelist, first downlink network bandwidth, first uplink network bandwidth, second downlink network bandwidth and second uplink network bandwidth. Application types in application whitelist include important applications and ordinary applications.

[0079] The first downlink network bandwidth and the first uplink network bandwidth are used to adjust the network bandwidth of ordinary applications running in the foreground, and the second downlink network bandwidth and the second uplink network bandwidth are used to adjust the network bandwidth of ordinary applications running in the background. The first downlink network bandwidth is greater than the second downlink network bandwidth, and the first uplink network bandwidth is greater than the second uplink network bandwidth.

[0080] In this step, the configuration completion command is input by a user into the electronic device executing this method embodiment; this user may be a server administrator. The server administrator may have permissions to configure information related to the vehicle network control policy. The on / off state of the switch corresponding to the vehicle network control policy is 0, indicating off (the vehicle network control policy is not executed); a value of 1 indicates on (the vehicle network control policy is executed). Applications included in the application whitelist have network access permissions, while applications not included in the application whitelist do not have network access permissions.

[0081] In some embodiments, optionally, before receiving the configuration completion instruction, the vehicle network control method provided in this application embodiment may further include: adding the third-party application to the application whitelist in response to the operation instruction to add the third-party application to the application whitelist.

[0082] For example, the server receives an application from a third-party application developer requesting that the application be added to the application whitelist. After the server administrator approves the application, the third-party application is added to the application whitelist. Correspondingly, the server responds to the instruction to add the third-party application to the application whitelist by adding the application to the whitelist.

[0083] For example, Figure 4 A schematic diagram illustrating the configuration of vehicle network control strategies for different roles according to an embodiment of this application, as shown below. Figure 4As shown, the server has an authentication mechanism that provides three user identities: administrator, system engineer, and third-party application developer. Different user identities can perform different operations after logging into the server. System engineers have the authority to input information such as vehicle model, vehicle infotainment system version number (i.e., the version number of the vehicle infotainment system), and important applications within the system. Third-party application developers can provide their application information and submit applications to be added to the application whitelist. Administrators have the highest authority to review information provided by system engineers, review applications submitted by third-party application developers, and edit in-vehicle network control policies, storing approved information on the server. Additionally, administrators can query the execution records and editing history of in-vehicle network control policies. Based on business needs, the most suitable in-vehicle network control policy and its corresponding execution switch are edited and then sent to the vehicle's infotainment system. Specific information in the in-vehicle network control policy includes, for example, the vehicle model and device code, application whitelist, first downlink network bandwidth, first uplink network bandwidth, second downlink network bandwidth, and second uplink network bandwidth. The delivery of in-vehicle network control policies can be precisely targeted to specific vehicle models and vehicles.

[0084] S302. In response to the configuration completion command, store the vehicle network control policy and the corresponding execution switch of the vehicle network control policy.

[0085] It is understandable that after receiving the configuration completion instruction containing the vehicle network control policy and the corresponding execution switch, the server, in response to the configuration completion instruction, stores the vehicle network control policy and the corresponding execution switch.

[0086] The vehicle network control method provided in this application embodiment receives a configuration completion instruction containing a vehicle network control policy and the corresponding execution switch. In response to the configuration completion instruction, it stores the vehicle network control policy and the corresponding execution switch, which enables convenient management and flexible configuration of the vehicle network control policy. In addition, based on the application whitelist included in the vehicle network control policy, it can provide application developers with an official way to optimize the vehicle network.

[0087] Based on the above embodiments, Figure 5 This is a signaling interaction diagram of an embodiment of the vehicle network control method provided in this application, wherein the vehicle terminal and the server are connected for communication. Figure 5 As shown, the method in this application embodiment may include:

[0088] S501. The vehicle terminal sends a request message to the server to obtain the vehicle network control policy and the corresponding execution switch of the vehicle network control policy. The request message carries the vehicle model and device code.

[0089] Accordingly, the server receives request messages from the vehicle's infotainment system.

[0090] For example, the vehicle's infotainment system can query the vehicle's model and vehicle equipment code (i.e., the vehicle's unique identifier) ​​through the system's interface. Based on these identifiers, it communicates with the server (also known as the cloud management platform), sending a request message to the server to obtain the vehicle network control policy and the corresponding execution switch. This request message carries the vehicle's model and equipment code. To ensure security when the infotainment system sends this request message to the server, the server can authenticate the message. Specific authentication methods can refer to current relevant technologies.

[0091] S502. The server sends a response message to the vehicle terminal. The response message includes the vehicle network control policy and the corresponding execution switch of the vehicle network control policy.

[0092] Accordingly, the vehicle-mounted system receives the response message from the server.

[0093] In this step, after receiving the request message from the vehicle's infotainment system, the server sends a response message to the system. This response message contains the vehicle network control policy and the corresponding execution switch. To ensure the security of the response message sent from the server to the vehicle's infotainment system, the information contained in the message can be encrypted. A specific encryption method could be the Secure Hash Algorithm-256 (SHA-256). Correspondingly, the vehicle's infotainment system receives the response message from the server, performs validity verification and parsing, and obtains the vehicle network control policy and the corresponding execution switch.

[0094] S503, the vehicle terminal detects the on / off status of the execution switch corresponding to the vehicle network control strategy.

[0095] In this step, the vehicle terminal can obtain the on / off status of the execution switch corresponding to the vehicle network control policy based on the response message sent by the server, and then detect the on / off status of the execution switch corresponding to the vehicle network control policy.

[0096] S504: When the vehicle's on / off state is "on", it obtains the target application that is running and has network access permissions.

[0097] For example, a switch state value of 0 indicates "off," meaning the vehicle network control policy is not executed; a switch state value of 1 indicates "on," meaning the vehicle network control policy is executed. Therefore, in response to the switch state being "on," the vehicle's infotainment system obtains the target application that is running and has network access permissions to execute the vehicle network control policy.

[0098] S505, the vehicle terminal determines the application type of the target application based on the application whitelist in the vehicle network control policy. The application type includes whitelisted applications and non-whitelisted applications. Whitelisted applications include important applications and ordinary applications.

[0099] For a detailed description of this step, please refer to [link / reference]. Figure 2 The relevant description of S202 in the illustrated embodiment will not be repeated here.

[0100] S506 The vehicle-mounted system adjusts the network bandwidth used by the target application based on the application type of the target application. Among them, the network bandwidth of important applications is not limited.

[0101] For a detailed description of this step, please refer to [link / reference]. Figure 2 The relevant description of S203 in the illustrated embodiment will not be repeated here.

[0102] S507. The vehicle terminal sends the current network usage information of the target application to the server for the server to update the vehicle network control policy. The current network usage information includes at least one of the target application's network bandwidth, network access latency, and network traffic used.

[0103] Accordingly, the server receives the current network usage information of the target application in the vehicle's infotainment system from the vehicle's infotainment system.

[0104] It's understandable that after adjusting the network bandwidth used by the target application, the vehicle's infotainment system can obtain the target application's current network usage information. This information is then sent to the server for updating the in-vehicle network control policy, providing data support for editing the server's in-vehicle network control policy. Correspondingly, the server receives the target application's current network usage information from the vehicle's infotainment system and stores it in a database. This information may include, for example, the target application's network bandwidth, network latency, network traffic usage, and whether the target application is not on the whitelist.

[0105] S508, The server responds to the instruction to complete the update of the vehicle network control policy based on the current network usage information, and stores the updated vehicle network control policy.

[0106] It is understandable that after receiving the target application's current network usage information, the server administrator can determine whether to update the vehicle network control policy based on this information. If the server administrator updates the vehicle network control policy based on the current network usage information, the server responds with an update completion instruction for the vehicle network control policy based on the current network usage information and stores the updated vehicle network control policy.

[0107] One embodiment of this application provides a vehicle network control method that obtains the vehicle network control policy and its corresponding execution switch by sending a request message from the vehicle's infotainment system to the server. The vehicle's infotainment system responds to the switch being enabled by obtaining a target application that is running and has network access permissions, effectively controlling whether the vehicle's infotainment system executes the vehicle network control policy. The vehicle's infotainment system determines the application type of the target application based on the application whitelist in the vehicle network control policy. Based on the application type, the vehicle's infotainment system adjusts the network bandwidth used by the target application, prioritizing the network bandwidth of important applications, which are not restricted. The vehicle's infotainment system sends the current network usage information of the target application to the server for updating the vehicle network control policy. This provides data support for editing the server's vehicle network control policy, resulting in a more effective policy. This allows for more rational use of the vehicle network based on the policy, improving network access speed for the vehicle's infotainment system and enhancing user experience. The server-side interface allows for convenient management and flexible configuration of in-vehicle network control policies. Furthermore, based on the application whitelist included in the in-vehicle network control policies, it provides application developers with official in-vehicle network optimization methods.
