[0024] Automobile parts terminal group: includes a collection of target automobile parts terminals configured on a car, but is not limited thereto, and may also include hardware devices for associating and managing each target automobile parts terminal. In actual application, since the configurations of different cars may be different, the collections of target automobile parts terminals included in the automobile parts terminal groups of different cars may be different.

[0025] The following describes the vehicle-side data management system of an embodiment of the present invention with reference to the accompanying drawings.

[0026] Figure 1 A block diagram of a vehicle data management platform provided by an embodiment of the present invention and a group of vehicle parts terminals corresponding to m vehicles are connected through a network.

[0027] Figure 2 A schematic block diagram of a network connection between an automobile data management platform provided by an embodiment of the present invention and an automobile component terminal group corresponding to a single vehicle.

[0028] Figure 3 A timing diagram of the interaction between an automobile data management platform and a target automobile component terminal provided by an embodiment of the present invention.

[0029] like Figures 1 to 3 As shown, a vehicle-side data management system according to an embodiment of the present invention includes an automobile data management platform and at least one automobile component terminal group, and the automobile data management platform is connected to each automobile component terminal group via a network.

[0030] Optionally, when an institution or enterprise related to the automobile industry uses the vehicle-side data management system to obtain the automobile data assets of a single vehicle and conduct a risk assessment on the vehicle, the vehicle-side data management system includes an automobile parts terminal group, and the automobile parts terminal group is the automobile parts terminal group corresponding to the vehicle.

[0031] Optionally, when relevant institutions or enterprises in the automobile industry use the vehicle-side data management system to obtain automobile data assets corresponding to a specified automobile type and conduct risk assessments on vehicles of the specified automobile type, the vehicle-side data management system includes a specified automobile parts terminal group, and the specified automobile parts terminal group is the automobile parts terminal group corresponding to the specified automobile type.

[0032] Optionally, when relevant institutions or enterprises in the automotive industry use the vehicle-side data management system to obtain the enterprise's overall automotive data assets and conduct an overall risk assessment of all the enterprise's vehicles, the vehicle-side data management system includes the automotive parts terminal group corresponding to all vehicles in the enterprise.

[0033] The automobile data management platform formulates classification and grading rules for each automobile parts terminal group based on the automobile type, and distributes each classification and grading rule to the corresponding automobile parts terminal group.

[0034] The above-mentioned classification and grading rules refer to the regulations and standards for the classification and level division of vehicle-side data, including classification and grading labels corresponding to the vehicle-side data, which are mainly formulated based on the importance and sensitivity of the vehicle-side data, and are used to guide and manage the processing and use of vehicle-side data; preferably, the levels of classification and grading rules are set from large to small granularity according to the same or similar characteristics or properties of the same category, and each granularity of classification and grading has a corresponding classification and grading label.

[0035] It can be understood that a vehicle-side data governance system in an embodiment of the present invention refers to the classification standards or classification regulations of automobile types in the automobile industry, and classifies automobile types with reference to the classification standards or classification regulations in the automobile industry. Therefore, the definition of automobile types will not be repeated here.

[0036] The automobile parts terminal group includes a set of target automobile parts terminals configured on a single vehicle (n target automobile parts terminals).

[0037] The above n refers to the number of target automobile component terminals that need to collect vehicle-side data and are included in the management system of the automobile data management platform. The n is determined based on the network connection of the automobile data management platform. The values ​​of n in different automobile component terminal groups are the same or different. For example, in Figure 1In the “target automobile component terminal n1”, “n1” represents both the last target automobile component terminal in automobile component terminal group 1 and the number of target automobile component terminals in automobile component terminal group 1. Similarly, “target automobile component terminal n m "n" in " m " represents both the last target auto parts terminal in the auto parts terminal group m and the number of target auto parts terminals included in the auto parts terminal group m, and n1 and n m When expressing quantities, their values ​​can be the same or different.

[0038] Optionally, each time the enterprise staff uses the vehicle-side data governance system to obtain the automobile data assets corresponding to a specified automobile type or a specified vehicle, n automobile parts terminals are selected as target automobile parts terminals in each automobile parts terminal group through the automobile data management platform, and the target automobile parts terminals in each automobile parts terminal group are connected through the network; wherein the target automobile parts terminals and the quantity selected by the enterprise staff each time may be the same or different.

[0039] Optionally, enterprise staff select n automobile parts terminals as target automobile parts terminals in each automobile parts terminal group in advance through the automobile data management platform, and set the selected n automobile parts terminals as default target automobile parts terminals. Each time the vehicle-side data governance system is used to obtain automobile data assets, the automobile data management platform directly connects to the n default target automobile parts terminals.

[0040] It should be noted that, in actual application, the automobile data management platform is connected to the automobile parts terminal groups of multiple automobiles through a network, and the n target automobile parts terminals in each automobile parts terminal group are connected to the automobile data management platform through a unified communication port on the automobile side. Therefore, the automobile data management platform can clearly define the corresponding relationship between the automobile parts terminal group (each target automobile parts terminal in the group) and the automobile side; preferably, each target automobile parts terminal in the automobile parts terminal group is equipped with a communication module, and each target automobile parts terminal uses its own communication module to connect to the automobile data management platform through a unified communication port on the automobile side. During the connection process, each target automobile parts terminal will be assigned a unique identifier, and the automobile data management platform can identify each target automobile parts terminal based on the identifier.

[0041] It should also be noted that, in some embodiments, the automobile data management platform selects the corresponding classification and grading rules according to the automobile type of the automobile parts terminal group, splits the selected classification and grading rules into classification and grading sub-rules that are compatible with n target automobile parts terminals, and sends them to the corresponding target automobile parts terminal (in the automobile parts terminal group); in other embodiments, the automobile data management platform selects the corresponding classification and grading rules according to the automobile type of the automobile parts terminal group and sends them to the automobile parts terminal group, and the automobile parts terminal group splits the selected classification and grading rules into classification and grading sub-rules that are compatible with n target automobile parts terminals, and sends them to the corresponding target automobile parts terminals. In actual application, each target automobile parts terminal of each car corresponds to a classification and grading sub-rule, and different target automobile parts terminals of the same car correspond to different classification and grading rules. The classification and grading rules corresponding to the same parts terminals of different cars may be the same or there may be differences.

[0042] The target automobile component terminal collects the vehicle-side data generated or processed by the corresponding automobile component, processes the collected vehicle-side data according to the source of the vehicle-side data, forms and stores vehicle-side data files, wherein the number of vehicle-side data files is greater than or equal to 1.

[0043] The above-mentioned vehicle-side data refers to various data generated or processed (including collection, transmission, storage, use, etc.) by automobile parts, such as vehicle status, driving information, fault information, etc., which can be collected and processed by the target automobile parts terminal.

[0044] The above-mentioned vehicle-side data file refers to a data file stored in the target automobile parts terminal, and the vehicle-side data file stores the vehicle-side data collected by the corresponding target automobile parts terminal; in actual application, a target automobile parts terminal stores at least one vehicle-side data file; the vehicle-side data file includes a file name and file content, and the file name includes the main file name, but is not limited to this, and the file name can also include a file suffix, path, etc.; in addition, the vehicle-side data file (name) is mainly automatically generated by the vehicle's driving computer system and other systems of the vehicle, and the file name has a certain correlation with the business-related information of automobile parts, automobile industry-related institutions or enterprises, and the file name and / or file content of the vehicle-side data file can include Chinese, English and numbers, etc. Optionally, the file suffix is ​​a manually defined content, which represents the processing method of the vehicle-side file (vehicle-side data), not the file saving format, for example, the file name of the vehicle-side data file is "brake system data.coll", where "brake system data" is the main file name, "coll" is the file suffix, and the definition or representation meaning of "coll" is manually set or manually defined.

[0045] It should be noted that the vehicle-side data collected by the target automobile part terminal may come from different automobile parts. Therefore, the collected vehicle-side data is classified and stored according to the source of the vehicle-side data, and the vehicle-side data from the same automobile part is sorted into the same vehicle-side data file. In this way, one or more vehicle-side data files are obtained; for example, when the target automobile part terminal is a domain controller, the domain controller collects vehicle-side data from automobile parts such as the engine control module, the transmission control module and the brake control module respectively. The domain controller (target automobile part terminal) sorts the vehicle-side data from the engine control module to form the first vehicle-side data file, sorts the vehicle-side data from the transmission control module to form the second vehicle-side data file, and sorts the vehicle-side data from the brake control module to form the third vehicle-side data file.

[0046] The target automobile parts terminal in the automobile parts terminal group receives the corresponding classification and grading rules, traverses the vehicle-end data files stored in itself, and classifies and grades the vehicle-end data in the traversed vehicle-end data files according to the classification and grading rules to obtain the classification and grading labels corresponding to the vehicle-end data; the target automobile parts terminal also summarizes the classification and grading labels corresponding to the vehicle-end data in all traversed vehicle-end data files to form a classification and grading list, and uploads the classification and grading list to the automobile data management platform.

[0047] The above-mentioned classification and grading labels refer to labels used to identify the categories and levels of vehicle-side data, including classification labels and grading labels for vehicle-side data. Classification labels are used to identify the classification of vehicle-side data, for example, vehicle-side data belongs to basic attribute data, vehicle operating condition data, environmental perception data, etc. Grading labels are used to identify the sensitivity and importance of vehicle-side data, for example, vehicle-side data is general data, important data, sensitive data, etc.

[0048] The above classification and grading list refers to a table that records the processing information of all vehicle-side data corresponding to a single target automobile component terminal, including the classification and grading labels of the vehicle-side data, but is not limited thereto, and may also include the source of the vehicle-side data, usage rights, etc. In actual application, one target automobile component terminal corresponds to one classification and grading list, and one classification and grading list corresponds to one or more vehicle-side data files.

[0049] It should be noted that the target automotive parts terminal classifies and grades the vehicle-side data according to the classification and grading rules (developed based on the vehicle type), and its classification and grading has nothing to do with business scenarios, etc.

[0050] It should also be noted that each target automotive component terminal adopts a distributed processing method to realize the discovery of vehicle-side data and the sorting of vehicle-side data assets, which reduces the burden on the automotive data management platform and greatly speeds up the data processing speed of the vehicle-side data governance system.

[0051] The automobile data management platform receives the classification and grading lists transmitted by each target automobile parts terminal in each automobile parts terminal group, and generates an automobile data asset ledger based on all the classification and grading lists for reference, thereby realizing efficient management of vehicle-side data.

[0052] The above-mentioned automobile data asset ledger is an account that records the management and usage of vehicle-side data assets. The recorded information includes vehicle-side data classification and grading information, but is not limited to this. It can also include the source of vehicle-side data, usage rights, etc.

[0053] It should be noted that a vehicle-side data governance system in an embodiment of the present invention supports data governance of unstructured data generated or processed by all terminals. When applied to automobile scenarios, it is suitable for classifying and grading various vehicle-side data and data governance, including ordinary vehicle-side data that can be sent out of the vehicle and privacy vehicle-side data that cannot be sent out of the vehicle. In addition, what the vehicle transmits to the automobile data management platform is a classification and grading list. In other words, what is sent out of the vehicle is the classification and grading label rather than the vehicle-side data itself, which can effectively protect the privacy and security of the vehicle-side data.

[0054] In a vehicle-side data management system of an embodiment of the present invention, the automobile data management platform formulates classification and grading rules for each automobile parts terminal group based on automobile type, and sends the classification and grading rules to the corresponding target automobile parts terminal group. Each automobile industry-related enterprise can create corresponding classification and grading rules for each automobile type through the automobile data management platform based on the automobile types owned by the enterprise, so as to meet the data management needs of each enterprise for different types of automobiles; The target automobile parts terminal in each automobile parts terminal group is used to collect and store vehicle-side data, and the stored vehicle-side data is classified and graded according to the received classification and grading rules to obtain the classification and grading labels corresponding to the vehicle-side data. All the obtained classification and grading labels are formed into a classification and grading list to clarify the vehicle-side asset distribution of each target automobile parts terminal in a single vehicle; The classification and grading lists corresponding to each target automobile part terminal in each automobile part terminal group are obtained through the automobile data management platform, and a complete automobile data asset ledger based on automobiles is generated, thereby facilitating subsequent risk assessment of automobile data assets based on the automobile data asset ledger.

[0055] In some embodiments, the automotive parts terminal group includes a domain controller, an IVI system, a T-BOX, and a gateway, etc.

[0056] In the automotive field, the above-mentioned domain controller is an electronic control unit (ECU) that is responsible for controlling and managing the electronic systems of specific functional domains in the car. There are many types of domain controllers in the automotive field, including power domain controllers, chassis domain controllers, body domain controllers, and infotainment domain controllers.

[0057] The above-mentioned IVI system (In-Vehicle Infotainment) is an in-vehicle comprehensive information processing system that provides functions such as entertainment, navigation, communication and vehicle information display.

[0058] The above-mentioned T-BOX (Telematics BOX, in-vehicle network communication terminal) is an automotive electronic device that enables communication between the vehicle and the outside world. It can provide a remote communication interface for the vehicle, exchange data with external devices, and provide emergency rescue, remote vehicle control and other functions.

[0059] In the automotive field, the above-mentioned gateway is an electronic control unit (ECU), which is responsible for managing and coordinating data transmission between different networks and ECUs, and providing functions such as protocol conversion, data interaction, and fault diagnosis.

[0060] It can be understood that the vehicle-side data collected by the domain control includes vehicle information, drive motor information, fuel cell information, engine data and vehicle location information; the vehicle-side data collected by the IVI system includes audio data, video data, vehicle status information and navigation data; the vehicle-side data collected by the T-BOX includes engine data, vehicle location information, vehicle mileage data and fuel consumption information; the vehicle-side data collected by the gateway includes engine control data, chassis control data and body control data.

[0061] In some embodiments, the automobile data management platform formulates classification and grading rules for each automobile component terminal group based on automobile type, including: The automobile data management platform formulates different classification and grading rules for each automobile type based on the automobile type. The classification and grading rules include classification and grading sub-rules of different granularities and classification labels and grading labels corresponding to classification and grading of different granularities. The classification label or grading label includes a range indication of the classification and grading sub-rules of the corresponding granularity.

As long as it can prompt the automobile management platform to formulate a rule-making basis for the classification and grading rules corresponding to the automobile parts terminal group, it belongs to the technical concept of the embodiment of the present invention.

[0063] Optionally, the automobile data management platform formulates different classification and grading rules for each automobile type based on the automobile type and the automobile parts corresponding to the automobile type, the business attribute information of the Internet of Vehicles service platform and the Internet of Vehicles information service data; wherein, the above-mentioned Internet of Vehicles service platform business attribute information refers to the information related to the enterprise business set in the classification and grading rules by relevant institutions or enterprises in the automobile industry, including relevant information on sales, repair, maintenance, operation, failure, etc., which is mainly used to classify and grade the vehicle-side data related to the enterprise business in the vehicle-side data file by using the classification and grading rules; the above-mentioned Internet of Vehicles information service data covers all data except user personal information in the process of Internet of Vehicles information service, including but not limited to data related to carriers such as vehicles, mobile smart terminals, roadside facilities and Internet of Vehicles service platforms. The definition of Internet of Vehicles information service data in the Internet of Vehicles industry standard "Technical Requirements for Security of Internet of Vehicles Information Service Data" (YD / T3751-2020) can be referred to.

[0064] Preferably, the automobile data management platform formulates different classification and grading rules for each automobile type based on the automobile type and the Internet of Vehicles information service data and user personal information corresponding to the automobile type; wherein, the above-mentioned user personal information refers to data information closely related to the user during the process of Internet of Vehicles information services such as data collection, transmission, use and destruction, and reference may be made to the definition of user personal information in the Internet of Vehicles industry standard "Requirements for Protection of User Personal Information of Internet of Vehicles Information Services" (YD / T3746-2020).

[0065] Specifically, the classification and grading granularity of vehicle-side data in the classification and grading rules can be set to single granularity or multiple granularities. In addition, the classification and grading rules set corresponding classification labels for different categories under each granularity, and subdivide the vehicle-side data of the same category in the classification with the finest granularity, and set corresponding grading labels; In some embodiments, when the classification and grading granularity of the vehicle-side data in the classification and grading rules is single-granularity, the classification and grading rules have only one level; at this time, the classification and grading rules include (independent and parallel) classification labels corresponding to different categories and (different) grading labels corresponding to the same category, and also include each classification label and classification and grading sub-rule corresponding to each grading label; for example, when the classification and grading granularity of the vehicle-side data is single-granularity classification and grading, the classification labels and grading labels of the classification and grading rules can be as shown in Table 1.

[0066]

[0067] In other embodiments, when the classification and grading granularity of the vehicle-side data in the classification and grading rules is multi-granularity, the classification and grading rules have multiple levels, and different standards or scales are used to classify the vehicle-side data from coarse to fine, and each category is subdivided in the classification with the finest granularity; at this time, the classification and grading rules include (independent and parallel) classification labels corresponding to different categories at each granularity (or in each level), and (different) grading labels corresponding to the same category in the classification with the finest granularity, and the classification label of each granularity is the parent classification label of the classification label of the next granularity. In addition, the classification and grading rules also include classification and grading sub-rules corresponding to each classification label at each granularity, and classification and grading sub-rules corresponding to each grading label under the finest granularity classification; for example, when the classification and grading granularity of the vehicle-side data includes coarse-grained and fine-grained classification and grading, the classification labels and grading labels of the classification and grading rules are shown in Table 2.

[0068] Table 2 Summary of multi-granularity classification and grading labels

[0069] It should also be noted that in the classification and grading rules, each independent and parallel classification label / grading label at each granularity is provided with a corresponding classification and grading sub-rule, and the classification and grading sub-rule corresponding to the classification label at each granularity includes a set of classification and grading rules corresponding to the sub-classification label of the classification label in the next granularity, and the classification and grading sub-rule corresponding to the classification label of the finest granularity includes a set of classification and grading rules corresponding to the grading label in the same category; for example, in Table 2, the classification and grading sub-rule corresponding to the classification label "basic attribute class data" in the coarse granularity includes a set of classification and grading sub-rules corresponding to its sub-classification labels "vehicle basic attribute data", "vehicle network mobile terminal application software basic attribute data" and "vehicle network service platform basic attribute data" in the fine granularity, and the classification and grading sub-rule corresponding to the classification label "vehicle basic attribute data" at the finest granularity includes a set of classification and grading sub-rules corresponding to the grading labels "vehicle general attribute data", "vehicle important attribute data" and "vehicle sensitive attribute data" in the category; In addition, when the automobile data management platform initially sets the classification and grading rules, the classification tags / grading tags are set correspondingly to the corresponding classification and grading sub-rules. Therefore, there is an association between the classification tags / grading tags at each granularity and the corresponding classification and grading sub-rules. The classification tags / grading tags at each granularity can lock the content / scope of the classification and grading sub-rules corresponding to the classification tags / grading tags at the corresponding granularity. Specifically, the classification label is used to lock the classification and grading sub-rule content / scope corresponding to the category at the corresponding granularity (including the classification and grading sub-rule content / scope corresponding to all sub-classification labels of the classification label in the next granularity). For example, in Table 2, the classification and grading sub-rule content / scope that can be locked based on the classification label "basic attribute class data" in the coarse granularity is the classification and grading sub-rule corresponding to the "basic attribute class data" category (including the classification and grading sub-rule content / scope corresponding to its sub-classification labels "vehicle basic attribute data", "Internet of Vehicles mobile terminal application software basic attribute data" and "Internet of Vehicles service platform basic attribute data" in the fine granularity); the classification and grading sub-rule content / scope corresponding to the category at the corresponding granularity (including the classification and grading sub-rule content / scope corresponding to its sub-classification labels "vehicle basic attribute data", "Internet of Vehicles mobile terminal application software basic attribute data" and "Internet of Vehicles service platform basic attribute data" in the fine granularity) can be locked through the finest granularity classification label. The classification and grading sub-rule content / scope corresponding to all grading labels in the category), for example, in Table 2, the classification and grading sub-rule content / scope that can be locked based on the classification label "vehicle basic attribute data" in the fine-grainedness is the classification and grading sub-rule corresponding to the "vehicle basic attribute data" category (including the classification and grading sub-rule content / scope corresponding to its corresponding grading labels "vehicle general attribute data", "vehicle important attribute data" and "vehicle sensitive attribute data"); the classification and grading sub-rule content / scope that is associated with it can be locked through the finest-grained grading label, for example, in Table 2, the classification and grading sub-rule content / scope that can be locked based on the finest-grained grading label "vehicle general attribute data" is the classification and grading sub-rule corresponding to the "vehicle general attribute data".

[0070] In some embodiments, the vehicle-side data file includes a file name and file content.

[0071] Correspondingly, the target automobile parts terminal traverses the vehicle-side data files stored in itself, and classifies and grades the vehicle-side data in the traversed vehicle-side data files according to the classification and grading rules, and obtains the classification and grading labels corresponding to the vehicle-side data, including: The target automobile parts terminal retrieves the file name of the vehicle-side data file stored in itself based on the classification and grading rules; It should be noted that the embodiment of the present invention adopts classification and grading rules to traverse or retrieve vehicle-side data files, and determines the classification and grading of each vehicle-side data file according to the file name of the vehicle-side data file. Since the classification and grading rules are pre-defined and fixed, it is only necessary to traverse or retrieve all vehicle-side data files once. In other words, no matter how many vehicle-side data files there are, the number of times the classification and grading rules are applied is fixed; (compared to the classification and grading method of matching each vehicle-side data file with the classification and grading rules one by one to determine the classification and grading of the vehicle-side data files, the number of times the vehicle-side data files match the classification and grading rules depends on the number of vehicle-side data files) the method of retrieving vehicle-side data files based on classification and grading rules can simplify the number of matches, reduce the computational complexity of the matching algorithm, and effectively improve the classification and grading efficiency of the vehicle-side data in the vehicle-side data files.

[0072] When a vehicle-side data file whose file name conforms to the classification and grading rules is retrieved, the classification label and grading label corresponding to the file name of the vehicle-side data file are obtained from the classification and grading rules, and are used as the initial classification label and initial grading label of the vehicle-side data in the vehicle-side data file, respectively.

[0073] The above-mentioned initial classification label refers to a classification label obtained by classifying based on the file name of the vehicle-side data file and the classification and grading rules corresponding to the type of vehicle to which it belongs.

[0074] The above-mentioned initial classification label refers to a classification label obtained by classification based on the classification rules corresponding to the file name of the vehicle-side data file and the type of vehicle to which it belongs.

[0075] It can be understood that according to the preset running order, the classification and grading rules are applied to retrieve ( / match) the file name of the vehicle-side data file. When a vehicle-side data file whose file name conforms to a classification and grading sub-rule in the classification and grading rules is retrieved, it means that the classification and grading sub-rule successfully matches the file name of the vehicle-side data file, and the classification label and grading label associated with the classification and grading sub-rule are obtained as the initial classification label and initial grading label of the vehicle-side data in the vehicle-side data file, respectively.

[0076] It should be noted that since the classification and grading rules only subdivide the vehicle-side data of the same category in the most fine-grained classification and set corresponding grading labels, no corresponding grading labels are set in other coarser classifications, so the initial grading labels can be empty.

[0077] Specifically, if the file name of the vehicle-side data file successfully matches the classification and grading sub-rule corresponding to the grading label at the finest granularity, the classification label associated with the classification and grading sub-rule is obtained as the initial classification label of the vehicle-side data in the vehicle-side data file, and the classification label of the classification corresponding to the classification label at the finest granularity is obtained as the initial classification label of the vehicle-side data in the vehicle-side data file. For example, in Table 2, if the classification and grading sub-rule corresponding to the grading label "vehicle general attribute data" includes fields such as the vehicle license plate number, and the vehicle-side data file whose file name includes the license plate number field is retrieved, the "vehicle general attribute data" is used as the initial classification label of the vehicle-side data in the vehicle-side data file, and the "vehicle basic attribute data" is used as the vehicle-side data file. According to the initial classification label of the vehicle-side data in the file; if the file name of the vehicle-side data file successfully matches the classification and grading sub-rule corresponding to the classification label at each granularity, the classification label associated with the classification and grading sub-rule is obtained as the initial classification label of the vehicle-side data in the vehicle-side data file, and the initial grading label of the vehicle-side data in the vehicle-side data file is empty. For example, in Table 2, if the classification and grading sub-rule corresponding to the fine-grained classification label "vehicle basic attribute data" includes fields such as vehicle basic attributes, and a vehicle-side data file whose file name includes the vehicle basic attribute field is retrieved, then "vehicle basic attribute data" is used as the initial classification label of the vehicle-side data in the vehicle-side data file, and the initial grading label of the vehicle-side data in the vehicle-side data file is empty.

[0078] Finding the initial classification label or the classification and grading sub-rule corresponding to the initial classification label from the classification and grading rules, identifying the file content of the vehicle-side data file, and matching the file content of the vehicle-side data file with the classification and grading sub-rule, and obtaining the final classification label and final grading label of the vehicle-side data in the vehicle-side data file according to the matching result; The above-mentioned final classification label refers to a classification label obtained by classifying the file content of the vehicle-side data file based on the corresponding classification and grading rules; wherein the corresponding classification and grading rules can be the initial classification label / the classification and grading sub-rules corresponding to the initial classification label or the classification and grading rules corresponding to the type of vehicle.

[0079] The above-mentioned final classification label refers to a classification label obtained by classification based on the file content of the vehicle-side data file and the corresponding classification and grading rules, and the final classification label is not empty; wherein the corresponding classification and grading rules can be the initial classification label / the classification and grading sub-rule corresponding to the initial classification label or the classification and grading rules corresponding to the type of vehicle.

[0080] It should be noted that since the file names of the vehicle-side data files are mainly automatically generated by the vehicle's onboard computer system and other systems of the vehicle, it is difficult for the vehicle data management platform or enterprise staff to clearly know their naming rules. Therefore, the vehicle-side data in the vehicle-side data files are classified and graded according to the file names of the vehicle-side data files. The initial classification labels and initial classification labels obtained may be classifications and grades at the finest granularity, or may be classifications at other coarser granularities. In order to perform fine-grained classification and grading of the vehicle-side data in the vehicle-side data files, it is necessary to classify and grade the vehicle-side data in the vehicle-side data files according to the file contents of the vehicle-side data files.

[0081] Specifically, when the initial classification label and the initial grading label of the vehicle-side data in the vehicle-side data file are the classification label and the grading label at the finest granularity, classifying and grading the vehicle-side data in the vehicle-side data file according to the file content of the vehicle-side data file belongs to verifying the accuracy of the initial classification label and the initial grading label. If the final classification label of the vehicle-side data in the vehicle-side data file is the same as the initial classification label, and the final grading label is also the same as the initial grading label, then the verification is correct; for example, in Table 2, the initial classification label of the vehicle-side data in the vehicle-side data file is "vehicle basic attribute data", the initial grading label is "vehicle sensitive attribute data", and the classification and grading sub-rule corresponding to the initial grading label "vehicle sensitive attribute data" The information includes the engine number and other related content. The classification and grading sub-rule corresponding to the initial classification label "vehicle sensitive attribute data" is directly locked from the classification and grading rules, and matched with the file content of the vehicle-side data file. If the file content of the vehicle-side data file includes relevant information about the engine number, the match is successful, indicating that the verification is correct. "Vehicle sensitive attribute data" is used as the final classification label of the vehicle-side data, and the classification label "vehicle basic attribute data" corresponding to the classification label is obtained as the final classification label of the vehicle-side data. At this time, the initial classification label and the final classification label of the vehicle-side data in the vehicle-side data file are both "vehicle basic attribute data", and the initial classification label and the final classification label are both "vehicle important attribute data"; When the vehicle-side data file only obtains the initial classification label and the initial grading label is empty, the file content of the vehicle-side data file is identified, and the file content of the vehicle-side data file is matched with the classification and grading sub-rule content locked by the initial classification label, and the vehicle-side data in the vehicle-side data file is further classified and graded in a fine-grained manner, and the grading label and classification label at the finest granularity are obtained as the final grading label and final classification label of the vehicle-side data in the vehicle-side data file respectively; for example, in Table 2, the initial classification label of the vehicle-side data file is "basic attribute class data", and the initial grading label is empty, and the classification and grading sub-rules corresponding to the initial classification label "basic attribute class data" are locked (including classification labels such as "vehicle general attribute data", "vehicle important attribute data", "vehicle sensitive attribute data", "vehicle network mobile terminal application software general attribute data", A set of classification and grading sub-rules corresponding to "important attribute data of vehicle network mobile terminal application software", "sensitive attribute data of vehicle network mobile terminal application software", "general attribute data of vehicle network service platform", "important attribute data of vehicle network service platform", and "sensitive attribute data of vehicle network service platform" are matched with the file content of the vehicle-side data file. If the classification and grading sub-rule corresponding to the "vehicle sensitive attribute data" includes relevant content such as the engine number, and the file content of the vehicle-side data file includes relevant information of the engine number, indicating that the classification and grading sub-rule corresponding to the grading label "vehicle important attribute data" is successfully matched, then "vehicle important attribute data" is used as the final classification label of the vehicle-side data in the vehicle-side data file, and accordingly "vehicle basic attribute data" is used as the final classification label of the vehicle-side data in the vehicle-side data file.

[0082] It should also be noted that, through the initial classification label or the initial grading label, the content / scope of the classification and grading sub-rule corresponding to the vehicle-side data file can be quickly locked in the classification and grading rules (in other words, the classification and grading sub-rule that matches the file name of the vehicle-side data file can be quickly filtered out from the classification and grading rules). After that, it is only necessary to match the file content of the vehicle-side data file with the locked / filtered classification and grading sub-rule content to further finely classify and grade the vehicle-side data in the vehicle-side data file, rather than matching the file content of the vehicle-side data file with the entire classification and grading sub-rule content corresponding to the corresponding car type to obtain further classification and grading. This can simplify the matching scope, reduce the computational complexity of the matching algorithm, and effectively improve the efficiency of fine classification and grading of the vehicle-side data in the vehicle-side data file.

[0083] When no vehicle-side data file whose file name conforms to the classification and grading rules is retrieved, the file content of the vehicle-side data file is identified, and the file content of the vehicle-side data file is directly matched with the classification and grading rules, and the final classification label and final grading label of the vehicle-side data in the vehicle-side data file are obtained according to the matching result; It is understandable that since the automobile data management platform formulates classification and grading rules based on the automobile type, the naming rules of the vehicle-side data files are mainly determined by the automobile's onboard computer system and other systems of the automobile. There is a strong correlation between the classification and grading rules and the naming rules of the vehicle-side data files. However, there may still be situations where the file name of the vehicle-side data file fails to match the classification and grading rules corresponding to the type of automobile to which it belongs. In this case, it is necessary to match the file content of the vehicle-side data file with the entire classification and grading rules in full to obtain the most fine-grained (final) classification label and (final) grading label corresponding to the vehicle-side data in the vehicle-side data file.

[0084] Based on the final classification label and final grading label of the vehicle-side data, the classification and grading labels corresponding to the vehicle-side data are formed.

[0085] It should be noted that when matching the file content of the vehicle-side data file with the corresponding classification and grading rules, if the match fails or a non-empty final grading label and final classification label are not obtained according to the matching result, it means that the vehicle-side data does not fall within the scope that needs to be collected and managed by the automobile data management platform. Furthermore, the classification and grading labels corresponding to the vehicle-side data do not fall within the scope that needs to be collected by the automobile data management platform. Therefore, the vehicle-side data can be ignored in the subsequent vehicle-side data governance process.

[0086] It should also be noted that the retrieval / matching rules used in the embodiments of the present invention may be components of the classification and grading rules, or may be rules independently set outside the classification and grading rules; wherein the retrieval / matching rules include field matching, field matching, regular expressions, etc., and are not limited to the above in actual application. It is also possible to retrieve / match vehicle-side data files based on AI algorithms to achieve the classification and grading function of the vehicle-side data files by matching the classification and grading rules with the vehicle-side data files. As long as the matching technology can achieve this function, it belongs to the technical concept of the present invention.

[0087] In some embodiments, when the automobile data management platform is connected to each automobile component terminal group through a network, the automobile data management platform allocates an identifier to each target automobile component terminal in each automobile component terminal group, which is recorded as the identifier of the target automobile component terminal.

[0088] It should be noted that the identification of the target automobile part terminal is used to enable the automobile data management platform to determine the corresponding target automobile part terminal based on the identification of the target automobile part terminal when it subsequently updates and / or analyzes the classification and grading list or the classification and grading list master list.

[0089] In some embodiments, the automobile data management platform formulates classification and grading rules for each automobile parts terminal group based on automobile type, and sends each classification and grading rule to the corresponding automobile parts terminal group, including: The automobile data management platform formulates corresponding classification and grading rules for each automobile type based on the automobile type; When the automobile data management platform is connected to the automobile parts terminal group through a network, the automobile type corresponding to the automobile parts terminal group and the identification of each target automobile parts terminal in the automobile parts terminal group are obtained; The automobile data management platform selects a corresponding classification and grading rule according to the automobile type corresponding to the automobile parts terminal group, splits the classification and grading rule into classification and grading sub-rules adapted to each target automobile parts terminal in the automobile parts terminal group, and establishes a first association relationship between the identifier of each target automobile parts terminal in each automobile parts terminal group and the corresponding classification and grading sub-rule; The automobile data management platform finds out the target automobile parts terminal corresponding to each classification and grading sub-rule according to the first association relationship, and sends each classification and grading sub-rule to the corresponding target automobile parts terminal.

[0090] It should be noted that the automobile data management platform binds the identification of each target automobile part terminal and the corresponding classification and grading rules one-to-one to form a first association relationship, so that the automobile data management platform can accurately send the classification and grading rules to the corresponding target automobile part terminal by querying the first association relationship, and at the same time, it is convenient for enterprise staff to efficiently manage the classification and grading rules of each target automobile part terminal through the automobile data management platform.

[0091] It should also be noted that the method of splitting the classification and grading rules into classification and grading sub-rules compatible with each target automobile part terminal in the automobile part terminal group on the automobile data management platform side and sending them to the corresponding target automobile part terminals can ensure that each target automobile part terminal in the automobile part terminal group can only receive the classification and grading sub-rules compatible with itself to process the vehicle-side data stored in itself, reducing the risk of data leakage, because each terminal cannot know the classification and grading sub-rules of other target automobile part terminals, so even if a target automobile part terminal is attacked, it will not immediately affect the security of the entire vehicle-side data management system; in addition, each target automobile part terminal can synchronously process the vehicle-side data files related to itself, improve data processing efficiency, and further improve the processing speed of the vehicle-side data management system.

[0092] In some embodiments, the automobile data management platform receives the classification and grading lists transmitted by each target automobile component terminal in each automobile component terminal group, and generates an automobile data asset ledger based on all the classification and grading lists, including: The automobile data management platform receives the classification and grading list transmitted by each target automobile parts terminal in each automobile parts terminal group, and automatically refreshes the classification and grading list and records the manual correction behavior when detecting that the classification and grading list has been manually corrected; wherein the corrected classification and grading list includes the classification and grading label corrected manually; It should be noted that since there may be inappropriate classification and grading labels in the classification and grading list, these classification and grading labels need to be modified manually; the company's staff logs in to the automobile data management platform to check each classification and grading list, and manually reviews and corrects each classification and grading list (according to the source of the vehicle-side data in the classification and grading list, usage permissions, etc.) to achieve vehicle-cloud-human collaborative linkage.

[0093] The automobile data management platform classifies and stores each classification and grading list according to the data source, and stores the classification and grading lists from the same automobile parts terminal group together. After receiving the classification and grading lists from all target automobile parts terminals corresponding to a single automobile parts terminal group, the platform deduplicates all the classification and grading lists corresponding to the automobile parts terminal group, and summarizes all the classification and grading lists corresponding to the automobile parts terminal group in order of receipt time to form a summary table of the classification and grading lists corresponding to the automobile parts terminal group; based on the summary table of the classification and grading lists corresponding to all automobile parts terminal groups, an automobile data asset ledger is generated.

[0094] The above-mentioned classification and grading list master table refers to a table that records the processing information of all vehicle-side data corresponding to a single automobile parts terminal group (a single vehicle), including the classification and grading labels of the vehicle-side data, but not limited to this, and may also include the source of the vehicle-side data, usage rights, etc.; in actual application, (a single vehicle or) an automobile parts terminal group corresponds to a classification and grading list master table.

[0095] In some embodiments, the automobile data management platform is further used to establish a second association relationship between the identifier of each target automobile part terminal in each automobile part terminal group and the received classification and grading list when receiving the classification and grading list transmitted by each target automobile part terminal in each automobile part terminal group; The automobile data management platform is also used to count the number of classification and grading labels that have been manually corrected in each classification and grading list, record it as the correction number, find out the classification and grading list whose correction number exceeds the threshold number, obtain the identification of the target automobile part terminal corresponding to the classification and grading list according to the second association relationship, and find out the classification and grading rules corresponding to the identification of the target automobile part terminal according to the first association relationship to update the classification and grading rules.

[0096] The above-mentioned number of corrections refers to the total number of classification and grading labels that have been manually corrected in a single classification and grading list. Each classification and grading list corresponds to a number of corrections.

[0097] The above-mentioned threshold number refers to the pre-set maximum number of classification and grading labels that can be manually modified in a single classification and grading list. One classification and grading list corresponds to one threshold number, and the threshold numbers corresponding to different classification and grading lists can be the same or different.

[0098] Specifically, in some embodiments, the classification and grading rules do not include matching rules, then the enterprise staff logs into the automobile data management platform, finds the corresponding classification and grading (sub) rules according to the identification of the target automobile part terminal, and reviews and updates / perfects the classification and grading (sub) rules; in other embodiments, the classification and grading rules include matching rules, then the enterprise staff modifies or adjusts the matching rules in the classification and grading rules on the basis of the above.

[0099] It should be noted that the automobile data management platform binds the identification of the target automobile parts terminal with the classification and grading rules through a first association relationship, and binds the identification of the target automobile parts terminal with the classification and grading list through a second association relationship. The identification of each target automobile parts terminal corresponds to a classification and grading rule, and corresponds to a classification and grading list, so that enterprise staff can efficiently manage the classification and grading rules and classification and grading lists of each target automobile parts terminal through the automobile data management platform.

[0100] In some embodiments, the automobile data management platform is further used to establish data access rights corresponding to the classification and grading labels according to the classification and grading labels in each classification and grading list, and form a data protection strategy corresponding to each classification and grading list; and send the data protection strategy corresponding to each classification and grading list to the corresponding target automobile parts terminal; The above-mentioned data protection strategy is the measures and rules implemented for the access, use and protection of all vehicle-side data (files) in the target automotive parts terminal. It is formulated based on the classification and grading labels of the vehicle-side data, including each classification and grading label and the corresponding vehicle-side data (file) protection measures. The vehicle-side data (file) protection measures include access control and encryption measures, but are not limited to these, and may also include backup and recovery, etc.

[0101] The target automobile component terminal is also used to control access to the vehicle-side data files stored in itself according to the received data protection strategy.

[0102] It should be noted that the automobile data management platform clarifies the sensitivity and security requirements of the vehicle-side data in each vehicle-side data file based on the classification and grading list, and formulates corresponding security measures and access control strategies to form a data protection strategy. Each target automobile component terminal performs access control on the vehicle-side data based on the received data protection strategy to ensure that vehicle-side data at different levels is properly protected.

[0103] In some embodiments, the automobile data management platform is also used to set an update mode for each classification and grading list, and synchronously update the classification and grading list master table and the automobile data asset ledger based on the update of each classification and grading list; wherein the update mode includes an incremental update mode and a periodic full update mode.

[0104] The above-mentioned incremental update mode refers to an update method of automatically detecting new vehicle-side data, obtaining new classification and grading labels based on the new vehicle-side data, and synchronizing the new classification and grading labels to the classification and grading list.

[0105] The above-mentioned periodic full update mode refers to a method of periodically performing full detection on the vehicle-side data, obtaining classification and grading labels based on the fully detected vehicle-side data, and synchronizing these classification and grading labels to the classification and grading list. In actual application, the classification and grading labels corresponding to the fully detected vehicle-side data are directly used to replace the original classification and grading labels in the classification and grading list.

[0106] It should be noted that the update modes adopted by different classification and grading lists can be the same or different.

[0107] It should also be noted that the classification and grading list should be updated, and the level of vehicle-side data should be adjusted and updated in a timely manner to ensure the accuracy of the classification and grading of vehicle-side data, and the classification and grading list master table and the automobile data asset ledger should be updated based on the updated content of the classification and grading list, so as to ensure the real-time, accuracy and completeness of the automobile data asset ledger formed based on the classification and grading list master table.

[0108] The following describes a method for using a vehicle-side data management system according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0109] Figure 4 A flowchart of a method for using a vehicle-side data management system provided in an embodiment of the present invention.

[0110] like Figure 4As shown, a method for using a vehicle-side data management system according to an embodiment of the present invention adopts the vehicle-side data management system of the above embodiment, and the method for using the vehicle-side data management system includes: Log in to the automobile data management platform, formulate classification and grading rules for each automobile parts terminal group based on the automobile type, and send each classification and grading rule to the corresponding automobile parts terminal group; The target automobile parts terminal in the automobile parts terminal group receives the corresponding classification and grading rules, and classifies and grades the vehicle-side data in the vehicle-side data file stored in itself according to the received classification and grading rules, obtains the classification and grading labels corresponding to the vehicle-side data, summarizes and compiles them into a classification and grading list, and uploads the classification and grading list to the automobile data management platform; Obtain each classification and grading list through the automobile data management platform, and generate an automobile data asset ledger based on all classification and grading lists.

[0111] In a method for using a vehicle-side data governance system according to an embodiment of the present invention, a vehicle data management platform is used to formulate classification and grading rules for each vehicle parts terminal group based on the vehicle type, and the formulated classification and grading rules are issued to each vehicle parts terminal group. Each automobile industry-related enterprise can create corresponding classification and grading rules for each vehicle type based on the vehicle type owned by the enterprise to meet the data governance needs of each enterprise for different types of vehicles; the target vehicle parts terminal in each vehicle parts terminal group is used to collect and store vehicle-side data, and the stored vehicle-side data is classified and graded according to the received classification and grading rules to obtain the classification and grading labels corresponding to the vehicle-side data, and all the obtained classification and grading labels are formed into a classification and grading list to clarify the vehicle-side asset distribution of each target vehicle parts terminal in a single vehicle; and the classification and grading list corresponding to each target vehicle parts terminal in each vehicle parts terminal group is obtained through the vehicle data management platform, and a complete vehicle data asset ledger based on all the classification and grading lists is generated in units of vehicles, so as to facilitate the subsequent risk assessment of vehicle data assets according to the vehicle data asset ledger.

[0112] In some embodiments, logging into the automobile data management platform, formulating classification and grading rules for each automobile parts terminal group based on automobile type, and issuing each classification and grading rule to the corresponding automobile parts terminal group, including: Log in to the automobile data management platform, select the target automobile parts terminal in each automobile parts terminal group, and formulate classification and grading rules for the selected target automobile parts terminal in each automobile parts terminal group based on the automobile type; the classification and grading rules include classification and grading sub-rules of different granularities and classification labels and grading labels corresponding to classification and grading of different granularities; wherein the classification label or grading label includes a range indication of the classification and grading sub-rule of the corresponding granularity; Corresponding classification and grading rules are issued to the target automobile parts terminals selected in each automobile parts terminal group.

[0113] It should be noted that enterprise staff select and connect target automobile parts terminals in each automobile parts terminal group through the automobile data management platform to determine the data source for forming a classification and grading list and generating an automobile data asset ledger.
