[0021] 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, and 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.

[0022] In view of the current problems such as poor automation of vehicle maintenance information maintenance and inability to guarantee the accuracy of the information displayed by the instrument after instrument replacement, this application provides a vehicle maintenance information maintenance system.

[0023] In one embodiment, the vehicle maintenance information maintenance system includes a vehicle-side terminal and a cloud-side terminal, with the vehicle-side terminal including an instrument cluster.

[0024] The vehicle-side system sends an information comparison request and the first maintenance information currently displayed on the instrument panel to the cloud after the instrument panel has been recently replaced. The cloud-side system compares the second maintenance information obtained locally on the cloud with the first maintenance information based on the information comparison request and transmits the comparison result to the vehicle-side system. The vehicle-side system displays the first or second maintenance information on the instrument panel based on the comparison result.

[0025] In this embodiment, the vehicle-side is the processing terminal configured in the vehicle, while the cloud-side is a processing terminal independent of the vehicle. Both the vehicle-side and the cloud-side can be configured with necessary hardware devices and software algorithms according to actual conditions and needs to realize the relevant functions of the vehicle maintenance information maintenance system. For example, in addition to the instrument panel used to display maintenance information, the vehicle-side may also include, but is not limited to, hardware devices such as the entertainment host already configured in the vehicle and the telematics-box (T-BOX) used for data interaction. The instrument panel, entertainment host, T-BOX, and other hardware devices are configured with relevant software algorithms to realize the vehicle maintenance information maintenance function. The cloud-side includes hardware devices such as remote computers and remote servers. The computers, servers, and other hardware devices are configured with relevant software algorithms to realize the vehicle maintenance information maintenance function. The vehicle-side and the cloud-side can communicate with each other. The communication method used can be any reasonable communication method such as cellular network communication, wireless local area network communication, satellite communication, or hybrid communication. The scope of protection of this application is not limited to the specific communication method between the vehicle-side and the cloud-side.

[0026] In this embodiment, after the instrument panel is replaced, it typically displays a default or initial value. The maintenance information currently displayed after the latest instrument panel replacement is defined as the first maintenance information. Since this first maintenance information is a default or initial value, it may not be accurate. Therefore, after the instrument panel is replaced and the newly replaced instrument panel is used for the first time, the vehicle will automatically send an information comparison request to the cloud. The cloud can obtain second maintenance information based on the specific conditions of the vehicle. This second maintenance information can be pre-stored in the cloud or calculated in real-time based on the vehicle's actual condition obtained from the cloud. After receiving the information comparison request from the vehicle, the cloud compares the second maintenance information obtained locally with the first maintenance information transmitted from the vehicle to determine which is more accurate. Finally, based on the comparison result, the vehicle displays the more accurate maintenance information (either the first or second maintenance information) on the instrument panel.

[0027] In this embodiment, based on the information interaction between the vehicle and the cloud, more accurate first or second maintenance information is displayed on the instrument panel. This allows users to obtain more accurate maintenance information, avoiding vehicle safety risks caused by untimely maintenance, or avoiding resource waste caused by premature maintenance. Furthermore, the above process requires no manual operation, improving the automation level of maintenance information and enhancing the user experience.

[0028] In one embodiment, the information comparison request includes maintenance and backup status information of the instrument.

[0029] The cloud-based system is used to calculate second maintenance information based on first maintenance information and maintenance interval information stored in the cloud when the maintenance backup function of the maintenance backup status information indicator instrument is disabled; or, when the maintenance backup function of the maintenance backup status information indicator instrument is triggered, the latest historical maintenance information stored in the cloud is used as the second maintenance information.

[0030] In this embodiment, the information comparison request includes the instrument cluster's maintenance backup status information. Specifically, whether the newly replaced instrument cluster can be used normally to back up or display maintenance information after replacement can be characterized by the maintenance backup status information. Different maintenance backup status information indicates different actual states of the instrument cluster's maintenance backup function. If the maintenance backup status information indicates that the instrument cluster's maintenance backup function is disabled, i.e., the instrument cluster does not have a maintenance backup function, then after the instrument cluster is replaced, the newly replaced instrument cluster displays a preset default value (e.g., the default value is 0). In this case, the cloud needs to recalculate the second maintenance information based on the first maintenance information and the maintenance interval information stored in the cloud, thereby ensuring the accuracy of the maintenance information displayed by the instrument cluster based on the comparison between the first and second maintenance information. If the maintenance backup status information indicates that the instrument cluster's maintenance backup function is triggered, i.e., the instrument cluster has a maintenance backup function, then after the instrument cluster is replaced, the newly replaced instrument cluster displays the original maintenance information, i.e., the maintenance information displayed by the old instrument cluster before the replacement. In this case, there is no need to recalculate the second maintenance information; the latest historical maintenance information stored in the cloud is directly sent to the vehicle as the second maintenance information, and the first and second maintenance information are directly compared to determine the more accurate maintenance information. Among them, historical maintenance information is maintenance information obtained based on the vehicle's historical maintenance records. For example, the remaining mileage for maintenance is obtained based on the latest maintenance mileage and the actual mileage of the vehicle. Another example is the remaining maintenance duration obtained based on the latest maintenance time and the vehicle's running time.

[0031] For example, maintenance backup status information includes backup status signals; backup status signals include several signals such as 0x0, 0x1, 0x2, and 0x3-F, specifically: If the backup status signal is 0x0, it means that the instrument backup function has not been triggered. At this time, the function of backing up maintenance information of the instrument has not started working. If the backup status signal is 0x1, it means that the instrument panel backup function has been triggered and the maintenance backup function has been started. Specifically, if the vehicle is equipped with the maintenance backup function, the vehicle will send a signal of 0x1 after the instrument panel is replaced. The instrument panel can store data and can perform a complete maintenance information backup and recovery process. If the backup status signal is 0x2, it means that the instrument panel backup function is disabled and the maintenance backup function is turned off. Specifically, if the vehicle itself is not equipped with a maintenance backup function, the vehicle will send a signal of 0x2 after the instrument panel is replaced. The instrument panel cannot store data and may need to recalculate the maintenance information before displaying it. If the backup status signal is 0x3-F, it indicates that the reserved status value has been started. The 0x3-F signal has no defined function and can be extended.

[0032] Based on the above, the vehicle continuously monitors the backup status signal. Only when the backup status signal is 0x1 or 0x2 will an information comparison request be sent to the cloud. Backup status signal 0x1 indicates that the maintenance backup function is triggered, and backup status signal 0x2 indicates that the maintenance backup function is disabled. Therefore, when the backup status signal is 0x1, the latest historical maintenance information stored in the cloud is used as the second maintenance information; when the backup status signal is 0x2, the second maintenance information is calculated based on the first maintenance information and the maintenance interval information stored in the cloud.

[0033] In this embodiment, when the maintenance backup function of the maintenance backup status information indicator is disabled, the second maintenance information needs to be recalculated based on the first maintenance information and the maintenance interval information stored in the cloud. For example, taking the vehicle's maintenance mileage as an example: Second maintenance remaining mileage = First maintenance remaining mileage + (Latest remaining maintenance mileage stored in the cloud - Second maintenance mileage interval). Second maintenance remaining time = the latest remaining maintenance time stored in the cloud; For example, the first vehicle maintenance is at 5000 km or 90 days. Subsequent maintenance intervals are 10000 km, with a maintenance duration of 180 days. The vehicle's actual mileage after the 5000 km first maintenance is 8000 km (the instrument panel displays 7000 km remaining mileage and 120 days remaining maintenance time). The vehicle will upload and update the real-time maintenance information to the cloud as historical maintenance information according to a preset cycle (e.g., daily, or each time the vehicle is started). If the instrument panel is damaged and replaced, and maintenance is backed up, the instrument panel will display the default initial maintenance information (e.g., 0 km and 0 days). Without maintenance backup, the instrument panel will display 5000 km remaining mileage and 180 days remaining maintenance time. To ensure the accuracy of the maintenance information, the cloud will recalculate the second maintenance information: second remaining mileage = 5000 + (7000 - 5000) = 7000 km, second remaining maintenance time = 120 days.

[0034] In this embodiment, based on maintenance backup status information, different maintenance backup strategies can be adopted for instruments with different functional configurations, thereby adapting to vehicles with different configurations and improving the flexibility and universality of the vehicle maintenance information maintenance system.

[0035] In one embodiment, the information comparison request also includes a unique identifier for the vehicle where the instrument cluster is located, such as a Vehicle Identification Number (VIN). The cloud can continuously store and update relevant information for multiple vehicles (including historical maintenance information, maintenance interval information, etc.), with each vehicle's relevant information stored in a one-to-one correspondence with its unique identifier. When a vehicle with a replaced instrument cluster sends an information comparison request to the cloud, the cloud, upon receiving the request, can read the maintenance interval information, historical maintenance information, and other relevant information of the vehicle with the replaced instrument cluster from its local storage based on the unique identifier in the request, thereby completing the maintenance information maintenance.

[0036] In one embodiment, the first maintenance information includes the remaining first maintenance information and the first maintenance interval information currently displayed on the instrument panel; the second maintenance information includes the remaining second maintenance information and the second maintenance interval information stored in the cloud.

[0037] In the cloud, it is used to calculate the difference between the remaining information of the first maintenance and the remaining information of the second maintenance, and to compare the remaining information difference with the difference threshold, and to compare the first maintenance interval information and the second maintenance interval information to obtain the comparison result; in the vehicle, it is used to display the second maintenance information on the instrument panel when the remaining information difference is greater than the difference threshold, or when the first maintenance interval information and the second maintenance interval information are inconsistent, and to display the first maintenance information on the instrument panel when the remaining information difference is less than or equal to the difference threshold, and the first maintenance interval information and the second maintenance interval information are consistent.

[0038] In this embodiment, the remaining maintenance information refers to the remaining amount of time before the next maintenance, including but not limited to the remaining mileage and remaining maintenance time. The remaining mileage indicates how many more miles the vehicle can travel before needing maintenance, and the remaining maintenance time indicates how much time remains until the next maintenance. The maintenance interval information refers to the standard interval between two maintenance services, including but not limited to the maintenance mileage interval and maintenance time interval. The maintenance mileage interval represents the standard mileage (e.g., 5000 km, 10000 km) between each two adjacent maintenance services, and the maintenance time interval represents the standard time period (e.g., 180 days, 365 days) between each two adjacent maintenance services.

[0039] In one embodiment, the first maintenance information and the second maintenance information contain the same specific data types. The first maintenance remaining information includes the remaining mileage and the remaining duration of the first maintenance, and the first maintenance interval information includes the first maintenance mileage interval and the first maintenance duration interval. Therefore, the second maintenance remaining information includes the second maintenance remaining mileage and the second maintenance remaining duration, and the second maintenance interval information includes the second maintenance mileage interval and the second maintenance duration interval. The identical data types of the first and second maintenance information facilitate comparison between them, further improving the accuracy of the maintenance information ultimately displayed by the instrument panel.

[0040] In this embodiment, when the cloud implementation compares the first maintenance information and the second maintenance information, it mainly compares two aspects: one is the comparison of the remaining maintenance information, and the other is the comparison of the maintenance interval information.

[0041] When comparing remaining maintenance information, firstly, the difference between the remaining information for the first and second maintenance services is calculated, and then this difference is compared to a threshold value. Further, if the remaining information for the first maintenance service includes both remaining mileage and remaining time, and the remaining information for the second maintenance service includes both remaining mileage and remaining time, then based on the remaining mileage for the first and second maintenance services, the difference in remaining mileage is calculated, and this difference is compared to a mileage difference threshold value. Simultaneously, based on the remaining time for the first and second maintenance services, the difference in remaining time is calculated, and this difference is compared to a time difference threshold value.

[0042] When comparing maintenance interval information, it is determined whether the first maintenance interval information and the second maintenance interval information are consistent. Furthermore, if the first maintenance interval information includes a first maintenance mileage interval and a first maintenance duration interval, and the second maintenance interval information includes a second maintenance mileage interval and a second maintenance duration interval, then it is determined whether the first maintenance mileage interval and the second maintenance mileage interval are consistent; at the same time, it is determined whether the first maintenance duration interval and the second maintenance duration interval are consistent.

[0043] In this embodiment, if the remaining information difference is greater than a difference threshold (i.e., the remaining mileage difference is greater than a mileage difference threshold, or the remaining duration difference is greater than a duration difference threshold), it indicates that the difference between the first maintenance information currently displayed on the instrument panel and the second maintenance information obtained from the cloud is too large, and the first maintenance information currently displayed on the instrument panel is inaccurate. In this case, the cloud sends the second maintenance information to the vehicle, and the vehicle displays the more accurate second maintenance information on the instrument panel. Furthermore, if the first maintenance interval information and the second maintenance interval information are inconsistent (i.e., the first maintenance mileage interval is inconsistent with the second maintenance mileage interval, or the first maintenance duration interval is inconsistent with the second maintenance duration interval), it indicates that the vehicle's maintenance interval information has been changed or is incorrect, and the first maintenance information is inaccurate. In this case, the cloud sends the second maintenance information to the vehicle, and the vehicle displays the more accurate second maintenance information based on the second maintenance interval information on the instrument panel. The difference threshold setting provides a certain tolerance range, avoiding frequent false triggering of maintenance information updates and improving the user experience. It should be noted that the specific values ​​of the difference thresholds, such as the mileage difference threshold and the duration difference threshold, can be set according to the actual situation and needs. The scope of protection of this application is not limited by the specific value of the difference threshold.

[0044] In this embodiment, when the remaining information difference is less than or equal to the difference threshold, and the first maintenance interval information is consistent with the second maintenance interval information (i.e., the remaining mileage difference is less than or equal to the mileage difference threshold, the remaining duration difference is less than or equal to the duration difference threshold, the first maintenance mileage interval is consistent with the second maintenance mileage interval, and the first maintenance duration interval is consistent with the second maintenance duration interval), it indicates that the first maintenance information currently displayed on the instrument panel is accurate. The cloud does not need to send the second maintenance information to the vehicle; the vehicle can directly display the first maintenance information on the instrument panel. This implementation method, where the first maintenance information currently displayed on the instrument panel is accurate, avoids redundant transmission of the second maintenance information between the cloud and the vehicle, thus avoiding waste of transmission resources.

[0045] In one embodiment, the vehicle-side is configured to display a maintenance update prompt message indicating that the first maintenance information has been updated to the second maintenance information before the instrument panel displays the second maintenance information, and to obtain first feedback information indicating whether the user agrees to the update of the first maintenance information to the second maintenance information; the cloud-side is configured to send the second maintenance information to the vehicle-side if the first feedback information indicates that the user agrees to the update of the first maintenance information to the second maintenance information, and to update the second maintenance information locally on the cloud to the first maintenance information if the first feedback information indicates that the user does not agree to the update of the first maintenance information to the second maintenance information.

[0046] In this embodiment, if it is determined that the first maintenance information currently displayed on the instrument panel is inaccurate and the instrument panel needs to display the second maintenance information sent from the cloud, a maintenance update prompt message is first sent to the user to inform them that the maintenance information displayed on the instrument panel will soon be updated from the first maintenance information to the second maintenance information. Optionally, the maintenance update prompt message can be displayed on the vehicle using one or more methods such as text, images, and voice. The display of the maintenance update prompt message can rely on any human-machine interaction device configured in the vehicle, such as the instrument panel or the central control screen. For example, the vehicle's central control screen can display "The remaining mileage for the next maintenance will be updated from 2000 kilometers to 1000 kilometers, and the remaining maintenance period will be updated from 180 days to 120 days. Do you agree to the operation?" and provide virtual buttons, voice recognition logic, and other configurations for user feedback on the vehicle. The user can input their first feedback message, whether they agree to the update of the first maintenance information to the second maintenance information, through any method such as the virtual button or voice reply on the vehicle. The vehicle will then transmit this first feedback message to the cloud.

[0047] In this embodiment, the cloud executes different processing logic based on the first feedback information. If the first feedback information received by the cloud indicates that the user agrees to update the first maintenance information to the second maintenance information, the cloud sends the second maintenance information to the vehicle, which then displays the second maintenance information on the instrument panel. If the first feedback information received by the cloud indicates that the user does not agree to update the first maintenance information to the second maintenance information, the cloud does not need to send the second maintenance information to the vehicle, and the vehicle's instrument panel still displays the first maintenance information; simultaneously, the cloud updates its local second maintenance information to the first maintenance information, ensuring data consistency between the vehicle and the cloud.

[0048] In this embodiment, the display of maintenance update prompts and the execution of different processing logics based on the first feedback information can provide users with an active selection process during the maintenance information maintenance process. This not only further prevents misoperation based on user confirmation and improves the accuracy of the maintenance information displayed by the instrument, but also ensures the user's right to choose and further enhances the user experience.

[0049] In one embodiment, the vehicle-side device is configured to, when the instrument panel displays second maintenance information, repeat the action of writing the second maintenance information to the instrument panel if writing the second maintenance information to the instrument panel fails, until the number of writing attempts reaches a threshold; and is configured to, when the number of writing attempts reaches the threshold and writing the second maintenance information to the instrument panel fails, continuously display an instrument panel fault message on the vehicle-side device, obtain second feedback information indicating whether the user agrees to replace the instrument panel again, and transmit the second feedback information to the cloud; the cloud-side device is configured to, if the second feedback information indicates that the user does not agree to replace the instrument panel again, update the second maintenance information locally on the cloud to the first maintenance information.

[0050] In this embodiment, after the cloud sends the second maintenance information to the vehicle, the vehicle needs to write the second maintenance information into the instrument cluster so that it can be displayed. However, when the vehicle writes the second maintenance information into the instrument cluster, various reasons such as instrument cluster malfunction or communication failure may cause the writing to fail. If the vehicle fails to write the second maintenance information into the instrument cluster on the first attempt, the process is not abandoned immediately. Instead, the writing process is repeated multiple times until a threshold number of writes is reached. If the number of writes does not reach the threshold number, any successful write operation will display the second maintenance information on the instrument cluster. If the number of writes reaches the threshold number and the writing of the second maintenance information into the instrument cluster still fails, the vehicle will continuously display an instrument cluster malfunction message through the instrument cluster, central control screen, and other human-computer interaction devices, prompting the user to replace the instrument cluster again to resolve the instrument cluster writing failure. The vehicle will also provide feedback channels such as virtual buttons and voice recognition devices. The user can provide feedback on whether they agree to replace the instrument cluster again, and the vehicle will generate a second feedback message based on the user's feedback and transmit the second feedback message to the cloud. If the second feedback information indicates that the user does not agree to replace the instrument cluster again, the vehicle's instrument cluster will still display the first maintenance information. Simultaneously, the cloud will update the local second maintenance information to the first maintenance information to ensure data consistency between the vehicle and the cloud. If the second feedback information indicates that the user agrees to replace the instrument cluster again, after updating the vehicle's instrument cluster again, the vehicle will resend an information comparison request and the latest first maintenance information currently displayed on the replaced instrument cluster to the cloud, repeating the vehicle maintenance information maintenance logic provided in the various embodiments of this application.

[0051] In this embodiment, the number of failed attempts to write the second maintenance information to the instrument is compared with a threshold value, providing multiple attempts to write the second maintenance information to the instrument and enabling automatic repair of temporary faults such as signal interference and temporary communication problems. The second feedback information provides a processing channel for resolving substantive instrument faults. The logic of repeating the maintenance process after replacing the instrument, and displaying the first maintenance information even without replacing the instrument, further ensures the reliability of the maintenance information. The threshold value can be set according to actual conditions and needs; for example, a threshold value of 3 is used. The scope of protection of this application is not limited by the specific value of the threshold value.

[0052] In one embodiment, the first maintenance information includes first vehicle maintenance information and first engine maintenance information; the second maintenance information includes second vehicle maintenance information and second engine maintenance information.

[0053] In this embodiment, maintenance information can be categorized based on the needs of the entire vehicle and the engine, and the maintenance information of the entire vehicle and the engine can be maintained independently. That is, the first maintenance information in each embodiment of this application can be the first vehicle maintenance information, and the second maintenance information can be the second vehicle maintenance information. A complete maintenance information scheme is implemented based on the first and second vehicle maintenance information. Similarly, the first maintenance information in each embodiment of this application can also be the first engine maintenance information, and the second maintenance information can be the second engine maintenance information. A complete maintenance information scheme is implemented based on the first and second engine maintenance information. Of course, with the development of technology, independent maintenance information can also be performed on any vehicle subsystem or component, such as the power battery, braking system, transmission system, and entertainment system, and the maintenance information maintenance schemes provided in the embodiments of this application can be implemented.

[0054] In this embodiment, the cloud can manage maintenance information for multiple vehicle models and multiple vehicles. The corresponding second maintenance information in the cloud can be configured with relevant files according to the vehicle model, thereby automating the maintenance process for multiple vehicles of the same model in batches. It can also automatically trigger the maintenance process for a single vehicle based on the vehicle's VIN. Through the cloud, remote management or updates of vehicle maintenance information can also be achieved, improving the automation level of maintenance information maintenance.

[0055] In one specific embodiment, the vehicle maintenance information maintenance system comprises a vehicle-side terminal and a cloud-based terminal. The vehicle-side terminal includes the instrument cluster, infotainment system, and T-BOX, while the cloud-based terminal utilizes the backend system of a Telematics Service Provider (TSP), referred to as the TSP backend. Taking whole-vehicle maintenance as an example, maintenance information includes remaining mileage, remaining maintenance time, maintenance mileage interval, and maintenance time interval. Figure 2 As shown ( Figure 2 For clarity, only step numbers are shown. The specific implementation logic of the vehicle maintenance information solution based on the vehicle maintenance information maintenance system is as follows: Step 201: Replace the instrument panel and power on the vehicle. Step 202: Determine whether the vehicle instrument panel is equipped with a maintenance backup function. If not, proceed to step 203; if yes, proceed to step 204. Step 203: The instrument displays the initial maintenance information by default, that is, the first maintenance information is the default initial maintenance information; the instrument sends the backup status signal 0x2 and the currently displayed first maintenance information to the T-BOX; proceed to step 205; Step 204: The instrument automatically backs up and restores maintenance information according to the maintenance backup function, that is, the first maintenance information is the restored backup maintenance information; the instrument sends the backup status signal 0x1 and the currently displayed first maintenance information to the T-BOX; proceed to step 205. Step 205: T-BOX sends an information comparison request to the cloud; Step 206: The TSP backend checks the backup status signal. If the backup status signal is 0x1, proceed to step 207. If the backup status signal is 0x2, proceed to step 208. Step 207: The TSP backend retrieves historical maintenance information and maintenance interval information based on the vehicle's VIN; based on the historical maintenance information, it determines the second maintenance information and proceeds to step 209. Step 208: The TSP backend retrieves historical maintenance information and maintenance interval information based on the vehicle's VIN, and combines it with the first maintenance information to recalculate the second maintenance information; then proceed to step 209. Step 209: The TSP backend calculates the difference between the remaining information of the first maintenance and the remaining information of the second maintenance, compares the difference between the remaining information with the difference threshold, and determines whether the first maintenance interval information and the second maintenance interval information are consistent. If the difference between the remaining information is greater than the difference threshold, or if the first maintenance interval information and the second maintenance interval information are inconsistent, proceed to step 210. If the difference between the remaining information is less than or equal to the difference threshold, and the first maintenance interval information and the second maintenance interval information are consistent, proceed to step 222. Step 210: Send the second maintenance information to the entertainment host via T-BOX; Step 211: The entertainment host displays a maintenance update prompt and obtains the first feedback information. It determines whether the first feedback information indicates that the user agrees to update the first maintenance information to the second maintenance information. If not, proceed to step 212; if yes, proceed to step 214. Step 212: Return the first feedback information to the TSP backend via T-BOX; Step 213: The TSP backend updates the local second maintenance information to the first maintenance information; Step 214: The entertainment host sends the second maintenance information to the instrument panel; Step 215: The instrument panel updates the real-time maintenance information to the second maintenance information; Step 216: Is the second maintenance information successfully written to the instrument? If not, proceed to step 217; if yes, proceed to step 221. Step 217: The entertainment host repeatedly initiates the request to write the second maintenance information to the instrument panel until the writing action reaches 3 times (the number of times threshold is set to 3 times). Step 218: If writing fails three times, the entertainment host interface will display a fault message for the instrument, obtain the second feedback information, and determine whether the second feedback information indicates that the user agrees to replace the instrument again. If not, proceed to step 219; if yes, proceed to step 222. For example, the instrument fault message displayed on the central control screen could be "Failed to write maintenance information to the instrument panel. The instrument panel may be faulty. Please confirm whether to replace the instrument panel." At the same time, a voice prompt would be given once. If the user does not confirm the operation, the central control screen will continue to display the pop-up message. The vehicle system will store the prompt message and the issued maintenance information until the user makes an operation. Step 219: Return the second feedback information to the TSP backend via T-BOX; Step 220: The TSP backend updates the local second maintenance information to the first maintenance information; Step 221: The entertainment host displays a message indicating that the second maintenance information has been successfully written, and then proceeds to step 222; For example, after the second maintenance information is updated, the instrument cluster sends a message of successful writing to the infotainment system. The infotainment system then displays "Maintenance information updated" on the central control screen (for 3-5 seconds) and simultaneously gives a voice announcement. Step 222: End this maintenance information maintenance process.

[0056] In this application, the vehicle maintenance information maintenance system includes a vehicle-side terminal and a cloud-based terminal. The vehicle-side terminal includes an instrument cluster. After the instrument cluster is recently replaced, the vehicle-side terminal sends an information comparison request and the first maintenance information currently displayed on the instrument cluster to the cloud. The cloud-based terminal compares the second maintenance information obtained locally on the cloud with the first maintenance information based on the information comparison request and transmits the comparison result to the vehicle-side terminal. The vehicle-side terminal displays either the first or second maintenance information on the instrument cluster based on the comparison result. In this solution, after the vehicle's instrument cluster is replaced, based on information exchange between the cloud and the vehicle-side terminal, the second maintenance information obtained locally on the cloud is compared with the first maintenance information currently displayed on the instrument cluster. This automatically maintains the maintenance information displayed on the instrument cluster to ensure the accuracy of the maintenance information and thus improve vehicle safety.
