[0002] With the rapid development of Internet of Vehicles technology, the information exchange between vehicles and infrastructure has become increasingly efficient. This information is not only widely used in basic functions such as real-time vehicle-machine interaction and safety warning, but is also uploaded to the cloud for big data analysis to support higher-level applications and services, such as in-depth analysis of traffic accidents, comprehensive evaluation of driving behavior, and continuous optimization of intelligent driving systems. However, to achieve these high-level functions, the authenticity and integrity of the data uploaded by the vehicle must be ensured, because the loss or omission of any key data may significantly reduce the accuracy of the analysis results, or even lead to erroneous conclusions.

[0003] Although the vehicle-side TBOX in the relevant technology has been equipped with a data retransmission function to deal with potential loss problems during data transmission, the existing mechanism still cannot guarantee the integrity of the data during forwarding to the cloud through the gateway, and there is a lack of authenticity verification mechanism for the retransmitted data, so the reissued data may not be fully trusted. Secondly, there is no integrity monitoring and reissue of other important vehicle data, which leads to the inability to fully guarantee the overall integrity of the vehicle data.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following describes a vehicle data correction method, a computer-readable storage medium, a vehicle data correction device, and a vehicle according to embodiments of the present invention with reference to the accompanying drawings.

[0033] Figure 1 1 is a flow chart of a vehicle data correction method according to an embodiment of the present invention.

[0034] Specifically, in some embodiments of the present invention, Figure 1 As shown, the vehicle data correction method includes:

[0035] S101, obtaining status information of each segment of the vehicle within a preset time period.

[0036] Specifically, in this embodiment, the status information includes status data of multiple measurement values, including mileage, power consumption, alcohol consumption, charging segment, overspeed segment, and power-on and power-off status. The mileage status data can be obtained by setting a mileage sensor, the power consumption status data can be obtained by the battery management system, the alcohol consumption status data can be obtained by the fuel management system, the charging segment status data can be obtained by the charging management system, the overspeed segment status data can be obtained by the ADAS system, and the power-on and power-off status status data can be obtained by the battery management system. Here, the present invention may not specifically limit the type of status information and the method of obtaining it. The status information of each segment of the vehicle within a preset time period is obtained, wherein the preset time period can be one minute, which is not specifically limited here.

[0037] S102, determining the integrity of the state information of each segment based on the continuity rule matching library.

[0038] Specifically, in this embodiment, the integrity of the state information of each fragment is determined based on the continuity rule matching library, wherein the continuity rule matching library includes a plurality of continuity rule matching information corresponding to a plurality of metric values ​​one by one, and the continuity rule matching information includes trigger matching information and update matching information. For example, the continuity rule matching library includes the following Table 1, the trigger matching information includes the trigger thresholds of the plurality of metric values, and the update matching information includes the time interval and the fragment interval. Table 1

[0039]

[0040] Among them, mileage>0 means the mileage difference is greater than 0, Charge_sts=3,4 means it is in the uncharged or fully charged state, Current>0 means the current is greater than 0, Engines=1 means the engine is in the running state, Charge_sts=1 means it is in the charging state, Current<0 means the current is less than 0, Veh_sts=0 means the motor is in the on state, Speed>75+ means the vehicle speed is greater than 75 km / h, Veh_sts=0,1 means the motor is in the on or off state. Taking the power consumption difference as an example, the interval between segments is in minutes. When the vehicle is not charged or fully charged, and the battery current of the vehicle is greater than 0, the trigger system obtains the power consumption difference every 10 seconds. If the power consumption difference is obtained at 10 seconds for the first acquisition, and the time to obtain the power consumption difference for the second time is greater than 10 seconds, for example, the power consumption difference is obtained at 12 seconds, then the second power consumption difference is determined to be abnormal, and the power consumption difference obtained for the second time is not recorded. The time information obtained is recorded. The power consumption difference is obtained at 10 seconds for the third to sixth times, then the state information of the segments composed of the mileage difference obtained from the first to the sixth times is determined to be incomplete state information. If the power consumption difference is obtained at 10 seconds for the seventh to the twelfth times, then the state information of the segments composed of the mileage difference obtained from the seventh to the twelfth times is determined to be incomplete state information.

[0041] S103, entering the complete status information of the segments into a database according to the integrity of the status information, and entering the incomplete status information of the segments into an OBS object.

[0042] Specifically, in this embodiment, after determining the integrity of the status information of each segment based on the continuity rule matching library, the complete status information of the segment and the incomplete status information of the segment are determined, and then the complete status information of the segment is entered into the database, and the incomplete status information of the segment is entered into the OBS object

[0043] S104, obtaining vehicle status supplementary information.

[0044] Specifically, in this embodiment, when the vehicle retransmits status information that was not uploaded before, the system can obtain the vehicle's status retransmission information, and the status information may include retransmission status data of multiple measurement values, including mileage, power consumption, alcohol consumption, charging segment, speeding segment, and power on and off status.

[0045] S105, integrating the incomplete state information of the segments based on the continuity rule matching library and the state supplement information to obtain successfully integrated state supplement information.

[0046] Specifically, in this embodiment, taking the power consumption difference in Table 1 as an example, the segment interval is minute level (but the specific detection frequency is in seconds, such as every 10 seconds). When the vehicle is in an uncharged or fully charged state, and the battery current of the vehicle is greater than 0, the system triggers a power consumption difference acquisition operation every 10 seconds. If the power consumption difference is successfully acquired at 10 seconds for the first time, and the time for acquiring the power consumption difference for the second time exceeds 10 seconds (for example, 12 seconds), it is determined that the second acquired power consumption difference is abnormal, and the second acquired power consumption difference is not recorded, but the time information of the acquisition is recorded. The third to sixth times are all within 1 If the power consumption difference is obtained at 0 seconds, it is determined that the status information of the segment composed of the mileage difference obtained from the first to the sixth time is an incomplete status information segment (due to the abnormality in the second acquisition), and the incomplete status information segment is entered into the OBS object. If the vehicle's status supplement information is obtained, the incomplete status information segment is integrated and processed according to the vehicle's status supplement information. Specifically, the relevant data in the status supplement information (such as the power consumption difference that should be obtained for the second time) is used to correct the power consumption difference obtained abnormally for the second time, thereby obtaining the status supplement information of successful integration and processing.

[0047] S106, entering the status supplement information into a database to correct the status information of the vehicle in the database within a preset time period.

[0048] Specifically, in this embodiment, after the status supplementary information of the successfully integrated processing is obtained, the status supplementary information is entered into the database to correct the status information of the vehicle in the preset period in the database, and the incomplete status information corresponding to the status supplementary information in the OBS is deleted, thereby ensuring that the status information in the database is complete and accurate within the preset period.

[0049] Furthermore, in some embodiments of the present invention, the continuity rule matching library includes a plurality of continuity rule matching information corresponding to a plurality of metric values ​​in a one-to-one correspondence, and the continuity rule matching information includes trigger matching information and update matching information.

[0050] Specifically, in this embodiment, the continuity rule matching library includes multiple continuity rule matching information corresponding to multiple measurement values ​​one by one, the continuity rule matching information includes trigger matching information and update matching information, the trigger matching information includes trigger thresholds of multiple measurement values, and the update matching information includes time intervals and segment intervals. As shown in Table 1 above, the continuity rule matching information also includes a label value, and the label value of each measurement value can be used to determine the authenticity of the status information of each segment of the vehicle. When the label value in the status information of each segment of the vehicle is consistent with the label value in the continuity rule matching library, it is determined that the status information of each segment of the vehicle is authentic. It should be noted that the mark value mile_diff corresponding to the mileage, the mark value Batt_con_diff corresponding to the power consumption, the mark value Fuel_diff corresponding to the alcohol consumption, the mark value Charge_label corresponding to the charging segment, the mark value Overspd_label corresponding to the speeding segment, and the mark value Vehsts_label corresponding to the power on and off status can be set by yourself, and the setting form of the label value in the status information of each segment of the vehicle is not specifically limited here.

[0051] Further, in this embodiment, if Figure 2 As shown, after determining the integrity of the state information of each segment based on the continuity rule matching library, the method further includes:

[0052] S201, obtaining the overall loss rate of state information, the data loss rate of metric values, and the data deviation amount of metric values.

[0053] Specifically, in this embodiment, after obtaining the status information of each segment of the vehicle within a preset time period, the total number of lost messages and the total number of reported messages can be obtained from the status information, the overall loss rate of the status information is equal to the total number of lost messages in the segment divided by the total number of reported messages, the data loss rate of the metric value is equal to the total number of lost messages in the corresponding segment divided by the total number of reported messages, and the data deviation of the metric value is equal to the estimated value of the metric value of the lost message in the corresponding segment. For example, the mileage difference obtained for the first time is 12 kilometers, the mileage difference obtained for the second time is abnormal, and the mileage difference obtained for the third time is 16 kilometers. Then, the mileage difference obtained for the second time can be estimated, and a value between 12 and 16 can be taken, such as 14 kilometers as the mileage difference obtained for the second time. In addition, the present invention may not specifically limit the method for obtaining the overall loss rate of the status information, the data loss rate of the metric value, and the data deviation of the metric value.

[0054] S202, displaying the overall loss rate of the status information, the data loss rate of the metric value, and the data deviation of the metric value through a quality display interface.

[0055] Specifically, in this embodiment, after obtaining the overall loss rate of status information, the data loss rate of metric values, and the data deviation of metric values, quality display can be performed in a BI (Business Intelligence) tool. In addition, the present invention may not specifically limit the selection of the quality display interface. This can improve the visual monitoring of data quality and enhance the accuracy of data integrity assessment.

[0056] Further, in some embodiments of the present invention, Figure 3 As shown, after integrating the incomplete state information of the fragments based on the continuity rule matching library and the state supplement information, the method further includes:

[0057] S301, obtaining an updated value of the overall loss rate of the state information, an updated value of the data loss rate of the metric value, and an updated value of the data deviation amount of the metric value.

[0058] Specifically, in this embodiment, after the incomplete state information of the fragments is integrated and processed based on the continuity rule matching library and the state supplementary information, the total number of lost message updates and the total number of reported messages are obtained from the state information again, the overall loss rate update value of the state information is equal to the total number of lost message updates in the fragment divided by the total number of reported messages, the data loss rate update value of the metric value is equal to the total number of lost message updates in the corresponding fragment divided by the total number of reported messages, and the data deviation update value of the metric value is equal to the estimated value of the lost message metric value in the corresponding updated fragment. For example, the mileage difference obtained for the first time is 12 kilometers, the mileage difference obtained for the second time is abnormal, and the mileage difference after the third update is 16 kilometers. Then, the mileage difference obtained for the second time can be estimated, and a value between 12 and 16 can be taken, such as 14 kilometers as the mileage difference obtained for the second time. In addition, the present invention may not specifically limit the method for obtaining the overall loss rate update value of the state information, the data loss rate update value of the metric value, and the data deviation update value of the metric value.

[0059] S302: Display the updated value of the overall loss rate of the status information, the updated value of the data loss rate of the metric value, and the updated value of the data deviation of the metric value through a quality display interface.

[0060] Specifically, in this embodiment, after obtaining the overall loss rate update value of the status information, the data loss rate update value of the metric value, and the data deviation update value of the metric value, quality display can be performed in the BI tool. In addition, the present invention may not specifically limit the selection of the quality display interface.

[0061] Further, in some embodiments of the present invention, Figure 4 As shown, after integrating the incomplete state information of the fragments based on the continuity rule matching library and the state supplement information, the method further includes:

[0062] S401, obtaining the status retransmission information of the failed integration process.

[0063] Specifically, in this embodiment, after the incomplete state information of the fragments is integrated based on the continuity rule matching library and the state supplement information, the integrity of the integrated state information is determined based on the continuity rule matching library, and the state supplement information of the failed integration is obtained.

[0064] S402, entering the status supplementary transmission information of the failed integration process into the OBS object.

[0065] Specifically, in this embodiment, after obtaining the status retransmission information of the failed integration process, the status retransmission information of the failed integration process is entered into the OBS object, thereby optimizing the data retransmission process and improving the efficiency and accuracy of data correction.

[0066] Further, in this embodiment, if Figure 5 As shown, the vehicle data correction method also includes:

[0067] S501, obtaining the storage duration of the incomplete segment status information in the OBS object.

[0068] Specifically, in this embodiment, the log or audit function of the OBS service can be used to obtain the storage duration of the incomplete status information of the fragment in the OBS object, for example, the creation time and the last modification time of the incomplete status information of the fragment in the OBS object can be obtained, so as to determine the storage duration of the incomplete status information of the fragment in the OBS object. Here, the present invention may not specifically limit the method for obtaining the storage duration of the incomplete status information of the fragment in the OBS object.

[0069] S502, when the storage time is longer than the preset time, if the vehicle status supplementary information is obtained, it is prohibited to integrate the incomplete status information.

[0070] Specifically, in this embodiment, after obtaining the storage duration of the incomplete status information in the OBS object, if the storage duration is greater than the preset duration, if the vehicle status supplementary information is obtained, the integration processing of the incomplete status information is prohibited. The preset duration can be set to 30 days, thereby saving server resources and improving the stability and reliability of the system. In addition, the present invention may not specifically limit the value of the preset duration.

[0071] In summary, according to the vehicle data correction method of the embodiment of the present invention, by obtaining the status information of each segment of the vehicle within a preset time period, and determining the integrity of the status information of each segment based on the continuity rule matching library, the complete status information of the segment is entered into the database according to the integrity of the status information, and the incomplete status information of the segment is entered into the OBS object, and the vehicle's status supplement information is obtained, thereby integrating the incomplete status information of the segment based on the continuity rule matching library and the status supplement information to obtain the successfully integrated status supplement information, and then entering the status supplement information into the database to correct the status information of the vehicle in the database within the preset time period, thereby improving the integrity and authenticity of the data in the database and optimizing the data supplement process.

[0072] Based on the vehicle data correction method proposed in the aforementioned embodiment of the present invention, the embodiment of the present invention further proposes a computer-readable storage medium on which a vehicle control program is stored. When the vehicle data correction program is executed by a processor, the vehicle data correction method of the aforementioned embodiment of the present invention is implemented.
