[0033] According to an aspect of an embodiment of the present application, a vehicle data processing method is provided. Optionally, the above-mentioned vehicle data processing method can be applied in a hardware environment as shown in Figure 1 Optionally, the above-mentioned vehicle data processing method provided by the present application can be applied in a vehicle terminal. Figure 1A side view of the vehicle terminal 101 is shown, which can travel on a travel surface 113.

[0034] In one embodiment, the space monitoring system 117 includes one or more space sensors and systems for monitoring a viewable area 105 in front of the vehicle terminal 101, and further includes a space monitoring controller 118.

The space sensors of the vehicle terminal space monitoring system 117 can include object localization sensing devices, which can include range sensors that can be configured to localize objects in front of the vehicle terminal 101, such as a preceding vehicle object.

[0035] The camera 108 is advantageously mounted and positioned on the vehicle terminal 101 in a position that allows for capturing images of the viewable area 105, where the viewable area 105 includes at least a portion of the travel surface 113 in front of the vehicle terminal 101 and including a trajectory of the vehicle terminal 101.

[0045] As an optional implementation, as shown in Figure 2 The processing method of vehicle data can be applied to the distributed storage device on the vehicle, and the specific steps include:

[0046] S202, in response to a vehicle data verification instruction, a plurality of vehicle data files are obtained from a plurality of vehicle storage areas respectively, wherein the vehicle data file includes vehicle data and verification data, and the plurality of vehicle data files correspond to the same vehicle data;

[0047] S204, in the case that the numerical relationship between the first quantity of target files in the plurality of vehicle data files and the second quantity of the plurality of vehicle data files satisfies the first verification condition, the reference file in the plurality of vehicle data files is determined as a to-be-restored file, wherein the verification data of each target file of the first quantity matches each other, and the verification data in the reference file does not match the verification data in the target file;

[0048] S206, in the case that the numerical relationship between the first quantity of target files in the plurality of vehicle data files and the second quantity of the plurality of vehicle data files does not satisfy the first verification condition, the plurality of vehicle data files are respectively determined as a plurality of to-be-restored files;

[0049] S208, performing a data recovery operation on the to-be-restored file.

[0050] It can be understood that in S202 in the above embodiment, in response to the vehicle data verification instruction, a plurality of vehicle data files are obtained from a plurality of vehicle storage areas respectively, and the plurality of vehicle storage areas each store a plurality of copies of the same vehicle data, each copy (vehicle data file) contains not only the actual vehicle data, but also a set of verification data for subsequent data verification and recovery.

[0051] It should be noted that the above storage area can be a storage disk area corresponding to each of a plurality of storage disks, or a plurality of storage disk areas divided by one storage disk, or a plurality of storage disk areas divided by a storage array composed of a plurality of storage disks, which is not limited here.

[0052] It should be noted that when the plurality of vehicle data files are obtained through the above step S202, it is necessary to check whether the numerical relationship between the number of target files (first number) in the obtained plurality of vehicle data files and the number of all files (second number) satisfies a preset first check condition. It should be noted that the above-mentioned target file refers to a file whose verification data matches each other.

[0053] Further, the obtained plurality of vehicle data files itself carries verification data, and it is checked whether the verification data of the obtained plurality of vehicle data files is consistent with each other, and the vehicle data file whose verification data is consistent with each other is taken as the above-mentioned target file, and according to the numerical relationship between the number of target files (first number) and the obtained plurality of vehicle data files (second number), in the case that the numerical relationship satisfies the first check condition, the reference file in the plurality of vehicle data files is determined as the file to be recovered.

[0054] Specifically, the above-mentioned numerical relationship can be the ratio of the first number to the second number, or in the case that the second number is within a certain numerical value or a certain numerical value range, the first number should have a minimum value.

[0055] Further, in response to the vehicle data verification instruction, after obtaining the plurality of vehicle data files from the plurality of vehicle-mounted storage areas respectively, one of the following is included:

[0056] Method one: in the case that the ratio between the first number and the second number is greater than or equal to the first number threshold, it is determined that the numerical relationship between the first number and the second number satisfies the first check condition;

[0057] Method two: in the case that the first number is greater than or equal to the second number threshold, it is determined that the numerical relationship between the first number and the second number satisfies the first check condition, wherein the second number threshold is determined according to the second number.

[0058] It can be understood that the above-mentioned method one is the determination of whether the numerical relationship satisfies the first check condition in the case that the above-mentioned numerical relationship is the ratio of the first number to the second number. For example, assuming that the preset first number threshold is 60% at this time, the total number of the obtained plurality of vehicle data files is 10, and the number of vehicle data files (target files) whose verification data is the same is 8 among the 10 vehicle data files. At this time, it can be determined that the ratio between the first number and the second number is 80%, which is greater than the preset first number threshold, and it is determined that the numerical relationship between the first number and the second number satisfies the first check condition.

[0059] In the case that the second quantity threshold is 8 and the first quantity is 8, it is determined that the value relationship between the first quantity and the second quantity satisfies the first check condition.

[0060] Optionally, the first quantity threshold and the second quantity threshold can be determined according to the importance of the data. In the case that the vehicle data is important data, a more stringent threshold is required, that is, a higher first quantity threshold and a second quantity threshold are set. For example, the first quantity threshold is set to 80%, and the second quantity threshold is set to 9 in the case that the number of backups is 10. In the case that the vehicle data is ordinary data, the threshold can be reduced to increase the recovery efficiency. For example, the first quantity threshold is set to 60%, and the second quantity threshold is set to 6 in the case that the number of backups is 10.

[0061] Further, in the case that it is determined that the value relationship satisfies the first check condition, the reference file in the plurality of vehicle data files is determined as the to-be-restored file. It can be understood that the check data in the reference file does not match the check data in the target file. Since the value relationship between the first quantity of the target file and the second quantity of the plurality of vehicle data files satisfies the first check condition, the target file is considered to be a correct data file, and the data file that does not match the check value of the target file is considered to be an error file and needs to be restored.

[0062] Optionally, if the value relationship between the first quantity of the target file and the second quantity of the plurality of vehicle data files does not satisfy the first check condition, it is considered that the correctness of the data of the target file is still in doubt, and the data recovery of other files cannot be performed according to the target file. All the vehicle data files obtained, including the target file, should be restored. That is, in the case that the value relationship between the first quantity of the target file in the plurality of vehicle data files and the second quantity of the plurality of vehicle data files does not satisfy the first check condition, the plurality of vehicle data files are respectively determined as a plurality of to-be-restored files.

[0063] It can be understood that there is no execution order between the above steps S204 and S206, and the execution is selected according to whether the numerical relationship between the first number of the target file in the plurality of vehicle data files and the second number of the plurality of vehicle data files satisfies the first check condition. In the case where the above numerical relationship satisfies the first check condition, the above step S204 is executed, and in the case where the above numerical relationship does not satisfy the first check condition, the above step S206 is executed. Through the above steps S204 and S206, the to-be-restored file can be determined in the case where the above numerical relationship satisfies the first check condition and in the case where the above numerical relationship does not satisfy the first check condition, respectively, and then the above step S208 is executed to perform the data recovery operation on the to-be-restored file.

[0064] Optionally, the above step S208, performing the data recovery operation on the to-be-restored file, comprises:

[0065] S208-1, in the case where the numerical relationship between the first number and the second number satisfies the first check condition, performing the data recovery operation on the to-be-restored file according to the target file;

[0066] S208-2, in the case where the numerical relationship between the first number and the second number does not satisfy the first check condition, performing the data recovery operation on the to-be-restored file according to the historical version file matched with the to-be-restored file.

[0067] It can be understood that after the to-be-restored data is determined through the above steps S204 and S206, the data recovery is performed on the to-be-restored file. For example, in the case where the to-be-restored file is the reference file determined through the step S204, the step S208-1 is executed to restore the reference file according to the content in the target file, so that the data content of the restored reference file is the same as the data content of the target file. In the case where the to-be-restored file is the plurality of vehicle data files determined through the above step S206, the above step S208-2 is executed to perform the data recovery operation on the to-be-restored file according to the historical version file matched with the to-be-restored file.

[0068] According to the above-mentioned embodiments of the present application, in response to a vehicle data verification instruction, a plurality of vehicle data files are obtained from a plurality of vehicle storage areas, wherein the vehicle data files include vehicle data and verification data, and the plurality of vehicle data files correspond to the same vehicle data; then, in the case that the numerical relationship between the first quantity of target files in the plurality of vehicle data files and the second quantity of the plurality of vehicle data files satisfies a first verification condition, a reference file in the plurality of vehicle data files is determined as a to-be-restored file, wherein the verification data of each of the target files of the first quantity matches each other, and the verification data in the reference file does not match the verification data in the target file; further, in the case that the numerical relationship between the first quantity of target files in the plurality of vehicle data files and the second quantity of the plurality of vehicle data files does not satisfy the first verification condition, the plurality of vehicle data files are determined as a plurality of to-be-restored files; then, a data recovery operation is performed on the to-be-restored files. Thus, the scheme of performing data recovery on to-be-restored data according to a plurality of data backup files containing the same data is realized, the reliability of data backup is enhanced by relying on a plurality of data backup files containing the same data, the problem that backup files cannot be recovered when too many backup files are damaged is avoided, and the reliability of data backup files is further enhanced by introducing the first verification condition, thereby solving the problem of low vehicle data storage reliability in the prior art.

[0069] As an optional embodiment, after obtaining the plurality of vehicle data files from the plurality of vehicle storage areas in response to the vehicle data verification instruction, the following steps are further included:

[0070] S1, performing a file verification operation on the plurality of vehicle data files according to the verification data included in each of the plurality of vehicle data files;

[0071] S2, in the case that the third quantity of first files that pass the file verification operation does not satisfy a second verification condition, determining the plurality of vehicle data files as a plurality of to-be-restored files;

[0072] S3, in the case that the third quantity of first files that pass the file verification operation satisfies the second verification condition, obtaining the verification data of each of the plurality of first files;

[0073] S4, performing data matching verification based on the verification data of each of the plurality of first files.

[0074] It can be understood that the above-mentioned steps S1 to S4 are file verification on the obtained plurality of vehicle data files and subsequent operations according to the verification result. Specifically, the above-mentioned step S1 is performed first. It should be noted that the file verification operation in the above-mentioned step S1 can be performed by using a cyclic redundancy check code (CRC code) or a hash code.

[0075] Specifically, the file checking operation is performed on each of the plurality of vehicle data files according to the checking data included in each of the plurality of vehicle data files, including at least one of the following:

[0076] In a first mode, when the checking data in the current vehicle data file is target cyclic redundancy check information, reference cyclic redundancy check information is determined according to the vehicle data included in the vehicle data file; when the reference cyclic redundancy check information matches the target cyclic redundancy check information, it is determined that the current vehicle data file passes the file checking operation. In a second mode, when the checking data in the current vehicle data file is target hash check information, reference hash check information is determined according to the vehicle data included in the vehicle data file; when the reference hash check information matches the target hash check information, it is determined that the current vehicle data file passes the file checking operation.

[0077] It can be understood that the above-mentioned first mode and second mode are respectively a mode of verifying data by cyclic redundancy check code and hash code. In an optional mode, the file checking operation can be performed on each of the plurality of vehicle data files according to the checking data included in each of the plurality of vehicle data files according to the first mode. Specifically, when the vehicle data is stored, cyclic redundancy coding (CRC coding) is performed according to the stored vehicle data to generate corresponding target cyclic redundancy information, and the target cyclic redundancy information is stored. When the data needs to be checked, the data to be checked is read and the cyclic redundancy information (reference cyclic redundancy information) is recalculated. When the recalculated reference cyclic redundancy information is consistent with the previously stored target cyclic redundancy information, it is considered that the data has not been changed, and at this time it is determined that the current vehicle data file passes the file checking operation.

[0078] In another optional mode, the file checking operation can also be performed on each of the plurality of vehicle data files according to the checking data included in each of the plurality of vehicle data files according to the second mode. Specifically, when storing, hash coding is performed according to the stored vehicle data to generate corresponding hash code (target hash check information). When the data needs to be checked, the data to be checked is read and the hash code is recalculated. When the recalculated hash code (reference hash check information) is the same as the hash code generated when storing, it is considered that the data has not been tampered with, and at this time it is determined that the current vehicle data file passes the file checking operation.

[0079] In yet another alternative, the first and second manners described above can also be used simultaneously to perform the file checking operation on the plurality of vehicle data files according to the verification data included in each of the plurality of vehicle data files. That is, the hash code and the CRC code can be used simultaneously. For example, when storing, first, the hash coding is performed according to the stored vehicle data to generate the corresponding hash code (target hash verification information), and then the CRC coding is performed on the hash code to generate the corresponding target cyclic redundancy information described above. When the data needs to be checked, the data to be checked is read and the hash code is first recalculated. When the recalculated hash code (reference hash verification information) is the same as the hash code generated when storing, the recalculated cyclic redundancy information (reference cyclic redundancy information) is further calculated. If the recalculated reference cyclic redundancy information is consistent with the previously stored target cyclic redundancy information, it is considered that the data has not changed. It should be noted that the above process of first performing hash coding and then performing CRC coding is only an example. CRC coding can be performed first and then hash coding. Here, no specific limitation is made.

[0080] Further, in the case where the third number of the first file through the file checking operation does not satisfy the second verification condition, the plurality of vehicle data files is determined as a plurality of files to be recovered, wherein the determination manner of whether the third number satisfies the second verification condition can be the value of the third number itself, or the ratio between the third number and the second number, specifically including:

[0081] S2-1, in the case where the ratio between the third number and the second number is less than a third number threshold, it is determined that the third number does not satisfy the second verification condition;

[0082] S2-2, in the case where the first number is less than a fourth number threshold, it is determined that the third number does not satisfy the second verification condition.

[0083] It can be understood that the step S2-1 is a step of determining whether the second verification condition is satisfied by the ratio between the third number and the second number. In the case where the ratio between the third number and the second number is less than the third number threshold, it is determined that the third number does not satisfy the second verification condition.

[0084] For example, the third number threshold is preset to be 80%, the second number of the plurality of vehicle data files is 10, and the third number of the first file through the file checking operation is 4. At this time, it is determined that the ratio between the third number and the second number is 40%, which is less than the preset third number threshold. At this time, it is determined that the third number does not satisfy the second verification condition.

[0085] It can be understood that the above step S2-2 is a step of determining whether the third quantity satisfies the second check condition by the value of the third quantity itself. When the third quantity is less than the fourth quantity threshold, it is determined that the third quantity does not satisfy the second check condition. For example, the fourth quantity threshold is preset to be 8, and the third quantity of the first file subjected to the file check operation is 4, which is less than the preset fourth quantity threshold. At this time, it is determined that the third quantity does not satisfy the second check condition.

[0086] It should be noted that the above second check condition indicates the number of files subjected to the encoding check, which represents that the data has not changed in the storage stage. However, the data may have been changed accidentally before being stored, for example, when the data is encoded before being stored. Even if the data is not changed subsequently, the stored data is already incorrect data, and therefore further verification is required, that is, the above steps S202 to S208 are performed. Whether the data is correct data is determined by comparing whether the check data of the files subjected to the data check is consistent with each other. When the check data of a certain file is inconsistent with that of other files, it is indicated that the file has changed before being stored, although it has not changed in the storage stage, resulting in incorrect data being stored.

[0087] In the above step S2, when the third quantity of the first file subjected to the file check operation does not satisfy the second check condition, the plurality of vehicle data files are determined as the plurality of files to be recovered. It can be understood that the third quantity not satisfying the second check condition indicates that the number of files subjected to the data check operation is too small, and the stored files have changed too much in the storage stage. Therefore, it can be directly determined that the stored files (the above plurality of vehicle data files) need to be recovered, that is, the plurality of vehicle data files are determined as the plurality of files to be recovered.

[0088] It can be understood that in the above step S3, the third quantity satisfying the second check condition means that the number of files subjected to the check operation is large, that is, the plurality of backup data files have changed little in the storage stage. At this time, it can be further determined whether the data stored by the files subjected to the check operation is correct data, that is, whether the data has changed in a stage other than storage (such as a writing stage). Specifically, the check data of each of the plurality of first files is first acquired. Further, the above step S4 is performed, and data matching check is performed based on the check data of each of the plurality of first files. The first files with the same check data are determined as the files passing the matching check, and the first files with different check data from other first files are determined as the first files not passing the matching check.

[0089] It is worth noting that although the determination of the second check condition occurs before the determination of the first check condition, the second check condition can be set more strictly than the first check condition. Specifically, in actual application, a default first check condition and a default second check condition are set to balance efficiency and security. In a daily non-emergency situation, data security can be further improved by setting more stringent check conditions. Since the determination of the second check condition occurs before the determination of the first check condition, the second check condition only needs to be changed to be more stringent than the original first check condition. This means that the tolerance for data that has changed during the storage stage is lower, resulting in a smaller number of data check failures. Therefore, the overall vehicle data needs to be restored, thereby improving data security.

[0090] Specifically, under the default condition, the number of data backups is 10, the first number threshold in the first check condition is 60%, the second number threshold is 6, and the third number threshold in the second check condition is 50%, and the fourth number threshold is 5. It can be understood that the second check condition is determined first to determine whether the third number satisfies the second check condition, and the numerical relationship is further determined to satisfy the first check condition when the third number satisfies the second check condition. In the case where data security needs to be improved, the third number threshold and the fourth number threshold in the second check condition are changed to higher values than the first number threshold and the second number threshold, for example, the third number threshold is set to 70%, and the fourth number threshold is set to 7.

[0091] It is worth noting that in the case where the third number threshold and the fourth number threshold in the second check condition are changed to higher values than the first number threshold and the second number threshold, if it is determined that the second check condition is not satisfied, the determination of whether the first check condition is satisfied is not performed.

[0092] For example, assuming that the number of data backups is 10, the first number threshold in the first check condition is 40%, and the second number threshold is 4. At this time, the third number threshold in the second check condition is set to 70%, and the fourth number threshold is set to 7, i.e. the second check condition is more stringent than the first check condition. In this case, if the number of vehicle data files that pass the file check operation is 5, it can be determined that the second check condition is not satisfied. Although in fact, the number of vehicle data files with the same check data in the vehicle data files that pass the file check operation can also be 5, i.e. there is a possibility of satisfying the first check condition, at this time, the determination of whether the first check condition is satisfied is not performed, and the multiple obtained vehicle data files are directly determined as files to be restored, and further data recovery operations are performed.

[0093] As an optional implementation, the data recovery operation is performed on the file to be recovered according to the historical version file matched with the file to be recovered, comprising:

[0094] S1, in the case that the last historical version file matched with the file to be recovered is found, performing the data recovery operation on the file to be recovered according to the last historical version file;

[0095] S2, in the case that the last historical version file matched with the file to be recovered is not found, performing the data recovery operation on the file to be recovered according to the initial version file matched with the file to be recovered.

[0096] It can be understood that in the process of performing the data recovery operation on the file to be recovered through the historical version file matched with the file to be recovered, the historical version file needs to be found first, in the case that the last historical version file matched with the file to be recovered is found, the data recovery operation is performed on the file to be recovered using the last historical version file, if the last historical version file matched with the file to be recovered is not found, the data recovery operation is performed on the file to be recovered using the initial version file matched with the file to be recovered.

[0097] Specifically, in the process of each data backup of a piece of data, the last historical version file and the initial version file are retained, in the process of data recovery, the historical version file is found, if the historical version file is not found, the initial version file is used to recover the file to be recovered, optionally, if the historical version file and the initial version file are not found, the data clearing operation is performed to delete the data to be recovered, so as to avoid transmitting invalid data with risk.

[0098] As an optional implementation, before the plurality of vehicle data files are acquired from the plurality of vehicle storage areas in response to the vehicle data verification instruction, further comprising:

[0099] S1, in the case that the data write request is received, determining the backup information of the vehicle data to be written according to the data type of the vehicle data to be written carried by the data write request, wherein the backup information comprises the backup quantity matched with the data type and the verification condition;

[0100] S2, writing the vehicle data file matched with the vehicle data to be written in the plurality of vehicle storage areas according to the backup information.

[0101] It can be understood that the above steps S1 and S2 are used for data backup according to the data type, for example, according to the importance of the data type, when the data type of the data to be written is important, more backup quantity and more stringent verification conditions are set, for example, the backup quantity of the data belonging to the important data type is set to 10, when there is one important data type of data to be backed up, 10 identical vehicle data files will be generated, and strict first verification condition and second verification condition are set, for example, the first quantity threshold in the above first verification condition is 80%, and the second quantity threshold is 8, and the third quantity threshold in the second verification condition is 70%, and the fourth quantity threshold is 7. It is worth noting that the above is only an example, and the backup quantity and the strictness of the verification condition can be dynamically set according to the importance of the data, which is not limited here.

[0102] As an optional implementation, after performing the data recovery operation on the files to be recovered, further comprising:

[0103] S1, in the case that the region state of the current vehicle storage region in the plurality of vehicle storage regions satisfies the region verification condition, obtaining a plurality of vehicle data files in the current vehicle storage region;

[0104] S2, sequentially performing file verification operation on the plurality of vehicle data files in the current vehicle storage region;

[0105] S3, in the case that the fourth quantity of the second file verified by the file verification operation in the current vehicle storage region does not satisfy the region verification condition, determining the plurality of vehicle data files in the current vehicle storage region as a plurality of files to be recovered;

[0106] S4, performing data recovery operation on the plurality of files to be recovered in the current vehicle storage region.

[0107] It should be noted that in the embodiment, the entire backup partition is verified and recovered as a whole by the above steps S1 to S4, taking each storage backup partition as an object.

[0108] Specifically, first, the above step S1 is performed, and in the case that the region state of the current vehicle storage region in the plurality of vehicle storage regions satisfies the region verification condition, a plurality of vehicle data files in the current vehicle storage region are obtained. It should be noted that the above region verification condition can be that the KV (Key-Value, key-value pair) storage is opened, for example, when the KV storage is opened, it is considered that the region state of the current vehicle storage region in the plurality of vehicle storage regions satisfies the region verification condition, and then a plurality of vehicle data files in the current vehicle storage region are obtained.

[0109] Further, the file verification operation is performed on the plurality of vehicle data files in the current vehicle storage area according to the above step S2, and it can be understood that the step is a traversal operation on the current vehicle storage area, each vehicle data file in the current vehicle storage area is traversed, and the file verification operation is performed on each vehicle data file. The verification process can refer to the foregoing embodiments, and will not be described here.

[0110] Further, in the case that the fourth quantity of the second file verified by the file verification operation in the current vehicle storage area does not satisfy the region verification condition, the plurality of vehicle data files in the current vehicle storage area are determined as a plurality of to-be-recovered files; and further, the above step S4 is performed to perform the data recovery operation on the plurality of to-be-recovered files in the current vehicle storage area.

[0111] Figure 3 is a schematic diagram of an optional vehicle data processing method according to an embodiment of the application, as shown in Figure 3 In the case that no data redundancy backup is performed, the backup architecture only includes the main storage and the backup storage, the data in the main storage is recovered through the backup storage, and if the backup file also appears abnormal, the data reading may be abnormal.

[0112] Figure 4 is a schematic diagram of another optional vehicle data processing method according to an embodiment of the application, as shown in Figure 4 The overall technical solution is divided into three parts, data storage backup, data verification, and data recovery. It should be noted that the backup mechanism using redundancy backup is used in the data storage link to ensure the reliability of the entire data. The verification method in the data verification link can be CRC verification or hash verification, etc. The data is verified through the selected verification method to ensure the validity of the data. In the data recovery link, a hierarchical recovery scheme is adopted.

[0113] The specific process of the above data backup link is described in detail in Figure 5 , as shown in Figure 5 The specific process of the data backup link includes steps S50 to S5,

[0114] S501, open the KV storage. The storage system opens the KV (Key-Value, key-value pair) storage.

[0115] S502, verify data validity. The data verification is realized by calling the data verification module 502.

[0116] S503, obtain valid backup data. Specifically, the last valid backup data is obtained and mapped to the memory 504.

[0117] S512, write data. This step triggers the write data operation to write data to the memory 504.

[0118] S522, synchronizing data.

[0119] S523, triggering a synchronization data operation.

It is worth noting that the above-mentioned database can be a vehicle storage area, and the above-mentioned database backup can be a backup file stored in the vehicle storage area, and a plurality of backup files constitute a database backup cluster 506.

[0121] The specific process of the above-mentioned data verification link is described in detail in the following Figure 6 As shown in the following Figure 6 The specific process of the data backup link includes steps S61 to S62.

[0122] S61, database validity verification link. Specifically, it includes steps S601 to S605. It should be noted that the above-mentioned database can be a vehicle storage area, and the above-mentioned database validity verification link is used to verify the validity of the data file in the vehicle storage area.

Store the verification value A2, compare the values of A1 and A2, complete the verification, and the verification calculation method can be CRC verification or Hash verification, which is not limited here.

[0126] S606, confirm invalid data. In the case that the KV storage cannot be opened, the stored data is directly identified as invalid data.

[0127] S604, whether passed. If the data verification in step S603 is passed, execute step S605 to confirm valid data. If not, execute step S606 to confirm invalid data.

[0128] S62, database consistency verification. It includes steps S611 to S615, and it should be noted that the above-mentioned database can be a vehicle storage area, and the above-mentioned database consistency verification is used to filter out valid files with the same verification value in the vehicle storage area.

[0129] S611, determine the number K of valid database files. According to step S61, K valid database files are filtered out.

[0130] S612, whether greater than N. N is a preset threshold, if yes, step S613 is executed, if no, step S616 is executed. It should be noted that if the K valid database files are greater than N, the second check condition is met, otherwise, if K is not greater than N, the second check condition is not met.

[0131] S613, determine the number of consistent databases G. The consistency of the check value of the data obtained from the above step S61 is compared, and the number of consistent databases G is screened out.

[0132] S614, whether greater than Z. Z is a preset threshold, if yes, step S615 is executed, if no, step S616 is executed. It should be noted that if the number of consistent databases G is greater than Z, the first check condition is met, otherwise, if G is not greater than Z, the first check condition is not met.

[0133] S615, restore the error data. The invalid database is restored according to the valid database, specifically, the invalid vehicle-mounted database file is restored according to the valid vehicle-mounted database file in the storage area.

[0134] S616, overall recovery. Trigger the overall recovery of the database file stored in the vehicle-mounted storage area.

[0135] The overall process of the above data recovery link is shown in Figure 7 As shown in Figure 7 S71, restore the damaged database according to the valid database, specifically, S701 to S706 are included. The invalid database file is restored according to the valid database file in the vehicle-mounted storage area through the above steps S701 to S706.

[0136] S701, start database overall recovery. Trigger the starting step of restoring the invalid database file according to the valid database file in the vehicle-mounted storage area.

[0140] S706, restore to initial version.

[0141] S704, restore to empty state.

[0142] Figure 8is a schematic diagram of another optional vehicle data processing method according to an embodiment of the present application, and the following takes Figure 8 a data reading and writing process as an example for illustration.

[0143] The diagnostic data is configured to deploy a storage backup scheme A, and the fault data and camera calibration parameters are configured to deploy a storage backup scheme B. The diagnostic data is synchronized to the data backup cluster A when being written. The diagnostic data is read from the valid database file (which can be stored in the on-board storage area) in the data backup cluster A.

[0144] The fault data and camera calibration data are synchronized to the data backup cluster B when being written. The fault data and camera calibration data are read from the valid database file (which can be stored in the on-board storage area) in the data backup cluster B.

[0145] Further, when the A storage backup scheme triggers the overall recovery scheme, the initial database recovery is directly used. It should be noted that the above initial database is directly generated when being configured. When the B storage backup scheme triggers the overall recovery scheme, the historical version is preferred, and the initial version is second.

[0146] Figure 9 is a schematic diagram of another optional vehicle data processing method according to an embodiment of the present application, and the process of configuring different backup schemes and storage is referred to Figure 9 . First, different backup schemes are configured. For example, Figure 9 two backup schemes A0 and A1 are configured in , and then the user stores the data into the specified database file in the on-board storage area according to the business. When the data generated by a certain business is ordinary data, the data backup scheme A1 is selected to generate two backup files. When the data generated by a certain business is important data, the data backup scheme A0 is selected to generate more backup files than ordinary data, for example, three backup files.

[0147] Further, when the KV storage is started, all data is read, and if the storage file cannot be opened, subsequent checking is not performed, and the storage file is directly marked as illegal.

[0148] Further, for all read data, CRC is calculated and added in sequence to obtain the real-time calculated CRC of the storage file. It should be noted that the special key-value pair CRC field is read, which is the CRC calculated when the KV storage is last closed and saved in the KV storage.

[0149] Further, it is checked whether the stored CRC and the CRC of the real-time read data are consistent. If they are not consistent, it means that the data is tampered with accidentally, and the database file is invalid.

[0150] If K is greater than N, CRC comparison is performed among the K database files stored in the on-board storage area, and if Z identical database files can be found, it is indicated that the KV storage is valid, and single storage file recovery can be performed to restore those invalid database files to a valid state. If Z identical valid database files cannot be found, it is indicated that the KV storage is invalid, and overall recovery is performed.

[0151] If K is greater than N, CRC comparison is performed among the K database files stored in the on-board storage area, and if Z identical database files can be found, it is indicated that the KV storage is valid, and single storage file recovery can be performed to restore those invalid database files to a valid state. If Z identical valid database files cannot be found, it is indicated that the KV storage is invalid, and overall recovery is performed.

[0152] In the overall recovery process, first, it is checked whether there is a historical version of the KV storage, such as the previous version, and if so, the previous version is restored. If not, it is checked whether there is an initial KV storage, and if so, the initial version is restored. If not, the KV storage is restored to an empty state to ensure that no invalid data at risk is passed.

[0153] It should be noted that, for each of the foregoing method embodiments, in order to simply describe, each is described as a combination of a series of actions, but those skilled in the art should know that the present application is not limited by the order of the described actions, because according to the present application, certain steps can be performed in other order or simultaneously.
