Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle certification technology, and specifically to a vehicle certification management method and apparatus. Background Technology
[0002] Under China's mandatory vehicle certification system, vehicle manufacturers face complex standard management and certification processes. On the one hand, current mandatory vehicle standards cover multiple areas such as safety, environmental protection, and energy consumption, and the content of these standards is constantly being updated, making it difficult for companies to quickly and comprehensively obtain and organize applicable standards. On the other hand, during product certification, it is necessary to accurately identify the standard items that must be met based on information such as vehicle model and component type, and determine the certification testing items, number of tests, and sample quantity. However, existing methods largely rely on manual comparison of standard documents and experience-based judgment, resulting in low efficiency and the potential for overlooking key standard items.
[0003] Therefore, it is necessary to develop a new vehicle certification management method and device. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a vehicle certification management method and device that can improve certification efficiency and avoid omitting key standard items.
[0005] In a first aspect, embodiments of this application provide a vehicle authentication management method, comprising the following steps:
[0006] Obtain vehicle standard documents and establish a standard database based on the vehicle standard documents. The standard database includes the mapping relationship between product information, standard clauses, and standard items.
[0007] Obtain product information of the product to be certified, and perform semantic matching and association analysis between the product information and the standard clauses in the standard database to identify the standard items that the product to be certified needs to meet;
[0008] Based on the identified standard items, the corresponding certification testing items are matched from the preset certification testing item knowledge base to form a certification testing item list. The certification testing item knowledge base includes the mapping relationship between standard items and certification testing items, testing methods and testing equipment.
[0009] Based on the certification and testing item list, the number of tests and the number of samples for each certification and testing item are determined by combining product production data and historical testing data, and a testing plan for the product to be certified is generated.
[0010] In the above technical solution, a standard database is established to realize the association mapping between product information, standard clauses and standard items. Combined with semantic matching, intelligent identification of standard items of the product to be certified is completed, replacing manual retrieval and matching operations. This significantly shortens the time for standard matching and test item sorting in the early stage of certification, reduces human operation errors, and improves certification efficiency. At the same time, by combining production scale and historical data to determine test parameters, the test plan is made more targeted, avoiding invalid tests, and balancing certification accuracy and efficiency, which helps to improve the overall efficiency of the certification process and strengthen data management.
[0011] One possible implementation further includes updating the standard database, specifically:
[0012] Obtain the status information of vehicle standard documents, which includes at least one of revision, repeal, and new release; if the status information of the vehicle standard documents changes, update the standard database and record the standard change history.
[0013] In the above technical solution, by acquiring standard document status information in real time and dynamically updating the standard database and recording change history, the automatic updating and dynamic management of vehicle standards can be realized. This helps enterprises keep abreast of standard dynamics and avoid certification failure or certification risks caused by standard lag or information omission. At the same time, the standard change history is easy to trace, further improving the efficiency of standard management and providing basic support for certification accuracy.
[0014] One possible implementation further includes: obtaining the certification test report of the certified product, performing structured processing on the certification test report and extracting first key information, and establishing a test report database based on the first key information; wherein the first key information includes the product model and the corresponding test information.
[0015] In the above technical solution, by structuring the test reports of certified products, extracting the first key information, and establishing a test report database, the unified collection and standardized management of test data is achieved, avoiding the problems of messy and unreusable test reports, improving the traceability and reusability of test data, providing data support for subsequent test scheme optimization and the determination of deemed items, and strengthening data management capabilities to ensure the traceability and certification process management of enterprise products.
[0016] One possible implementation is that the first key information includes the product model, certification and testing items, test results, and certification time.
[0017] In the above technical solution, by clarifying the specific content of the first key information (product model, certification and testing items, test results and certification time), the data in the test report database is made more complete and targeted, which facilitates the rapid retrieval of historical data for the corresponding products and testing items, improves the efficiency of data retrieval and comparison, and provides more accurate data support for the reuse of historical test data, adjustment of test scheme parameters, and determination of deemed items.
[0018] One possible implementation is that when the product to be certified is a new product, the second key information of the new product is obtained; the second key information is compared with the data in the test report database; if the similarity is greater than a preset threshold, it is determined to be a deemed item, and the test results of the corresponding certified item are obtained from the test report database; the second key information includes at least one of vehicle type, body structure parameters, power type, drive type, tire specifications, and mandatory certification components.
[0019] In the above technical solution, by acquiring the second key information of the new product and comparing it with the historical data in the test report database, intelligent judgment of deemed items can be achieved. For deemed items that meet the conditions, the test results of certified items can be directly reused, effectively avoiding repeated testing, reducing the consumption of test samples and the investment of testing time, and significantly reducing the certification and testing costs and time costs of enterprises.
[0020] One possible implementation involves determining the number of tests and sample quantities for each certification testing item based on the certification testing item list, combined with product production data and historical testing data. Specifically:
[0021] Pre-defined correspondence: A correspondence between production data and basic testing parameters is established in advance. The basic testing parameters include the number of benchmark tests and the number of benchmark samples for each certification testing item.
[0022] Obtain and match basic parameters: Obtain the actual production data of the product to be certified, and based on the correspondence between the production data and the basic testing parameters, match the benchmark number of tests and the benchmark sample quantity for each certification testing item of the product.
[0023] Retrieve and extract historical data: Retrieve historical test data for each certification test item corresponding to the product to be certified from the test report database, and extract historical test data items and data anomaly records;
[0024] Dynamically adjust detection parameters: If the similarity comparison of historical detection data is greater than or equal to the preset qualified threshold and there are no consecutive abnormal detection records, then the detection will be carried out according to a preset ratio based on the benchmark detection number and benchmark sample number; if the similarity comparison of historical detection data is less than the preset qualified threshold, or there are consecutive abnormal detection records, then the detection number will be increased according to a preset ratio based on the benchmark detection number and benchmark sample number.
[0025] Determine and integrate the final solution: Based on the results of dynamic adjustments, determine the final number of tests and the number of samples for each certification testing item, and integrate these final parameters into the testing solution for this certification.
[0026] In the above technical solution, the basic parameters for testing are determined by combining product production data, and the number of tests and samples are dynamically adjusted by combining historical testing data. This makes the testing plan more in line with the actual situation of the product, avoids certification risks caused by insufficient testing, and avoids cost waste caused by excessive testing. It not only ensures the accuracy and rigor of certification testing, but also realizes the rational allocation of testing resources, further reduces certification costs and improves certification efficiency. At the same time, it strengthens the value of data management by reusing historical data.
[0027] Secondly, the vehicle authentication management device provided in the embodiments of this application includes:
[0028] The standard library construction module is used to obtain vehicle standard files and establish a standard database based on the vehicle standard files. The standard database includes the mapping relationship between product information, standard clauses, and standard items.
[0029] The standard item identification module is used to obtain product information of the product to be certified, and perform semantic matching and correlation analysis between the product information and the standard clauses in the standard database to identify the standard items that the product to be certified must meet.
[0030] The testing item matching module is used to match corresponding certification testing items from a preset certification testing item knowledge base based on the identified standard items and form a certification testing item list. The certification testing item knowledge base includes a mapping relationship between standard items and certification testing items, testing methods and testing equipment.
[0031] The testing plan generation module is used to determine the number of tests and the number of samples for each certification testing item based on the certification testing item list, combined with product production data and historical testing data, and to generate a testing plan for the product to be certified.
[0032] In the above technical solution, through the synergistic effect of various modules, the process of standard database construction, intelligent identification of standard items, matching of test items, and generation of test solutions is modularized and automated, replacing the tedious manual operations, significantly shortening the pre-certification preparation time, reducing human error, and improving the efficiency and accuracy of the certification process; at the same time, it realizes the standardized management of standard data and test data, provides enterprises with comprehensive data support, strengthens data management capabilities, and helps enterprises complete vehicle certification efficiently.
[0033] One possible implementation also includes:
[0034] The standard library update module is used to obtain the status information of vehicle standard documents. The status information includes at least one of revision, repeal, and new release. If the status information of the vehicle standard documents changes, the standard database is updated and the standard change history is recorded.
[0035] In the above technical solution, the standard library update module enables real-time acquisition of standard document status and dynamic updating of the standard database, ensuring that the content in the standard database is consistent with the latest standards. This helps enterprises keep abreast of standard developments and avoid certification failures or risks caused by outdated standards. At the same time, recording the history of standard changes facilitates traceability, further improving the efficiency of standard management and providing a basic guarantee for the overall certification efficiency and accuracy of the device.
[0036] One possible implementation also includes:
[0037] The testing report management module is used to obtain the certification testing reports of certified products, perform structured processing on the certification testing reports and extract first key information, and establish a testing report database based on the first key information; wherein, the first key information includes product model, certification testing items, testing results and certification time.
[0038] In the above technical solution, the test report management module realizes the structured processing of test reports, extraction of key information and construction of test report database, realizes unified management and standardized storage of test data, improves the traceability and reusability of test data, and avoids the problems of messy and difficult-to-retrieve test data; at the same time, it provides accurate and complete historical data support for the test plan generation module and the deemed project identification module.
[0039] One possible implementation also includes:
[0040] The deemed item identification module is used to obtain the second key information of the new product when the product to be certified is a new product; compare the second key information with the data in the test report database; if the similarity is greater than a preset threshold, it is determined to be a deemed item, and the test results of the certified item are obtained from the test report database; the second key information includes at least one of vehicle type, body structure parameters, power type, drive type, tire specifications, and mandatory certification components.
[0041] In the above technical solution, the identification module for deemed items enables intelligent determination of deemed items for new products and reuse of historical test results, effectively avoiding repeated testing, reducing the consumption of test samples and the investment of testing time, and significantly reducing the certification testing costs and time costs for enterprises; at the same time, it improves the automation and efficiency of the certification process.

Detailed Implementation
[0049] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.
[0050] The terms “first,” “second,” etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0051] Please see Figure 1 This is a flowchart of a vehicle authentication management method disclosed in an embodiment of this application. A vehicle authentication management method includes the following steps:
[0052] Obtain vehicle standard documents (e.g., mandatory standard documents) and establish a standard database based on these documents. The standard database includes mappings of product information, standard clauses, and standard items. For example, web crawler technology can be used to automatically retrieve automotive standard documents published on official websites such as the National Standards Full-Text Disclosure System, the Standardization Administration of China, and the Ministry of Industry and Information Technology. These documents include national standards, industry standards, and related policies and regulations. The retrieved standard documents undergo format conversion and text extraction. Natural language processing technology is used to extract key information such as the standard's name, publication date, and scope of application. This information is then stored in the standard database according to the standard's category (e.g., safety, environmental protection, energy consumption), thus establishing a structured standard database.
[0053] The system acquires product information for the product to be certified and performs semantic matching and correlation analysis between this information and standard clauses in the standard database to identify the standard items the product must meet. For example, companies input product information, including vehicle type (passenger car, commercial vehicle), vehicle parameters (size, weight, powertrain type), and component configuration details, through the system interface. Using natural language processing and machine learning algorithms, the system performs semantic matching and correlation analysis between the input product information and standard clauses in the standard database to automatically identify the standard items the product must meet. For instance, based on parameters such as battery capacity and driving range of electric vehicles, the system automatically correlates them with relevant standards for energy consumption and safety of new energy vehicles.
[0054] Based on the identified standard items, the corresponding certification testing items are matched from the preset certification testing item knowledge base to form a certification testing item list. The certification testing item knowledge base includes the mapping relationship between standard items and certification testing items, testing methods and testing equipment.
[0055] Based on the certification testing item list, combined with product production data and historical testing data, the number of tests and sample quantities for each certification testing item are determined, and a testing plan for the product to be certified is generated. For example, for mass-produced passenger vehicles, five sample vehicles need to be selected for key safety testing items, and each sample vehicle needs to be tested three times; for components, different sampling quantities and testing frequencies are set according to their complexity and importance.
[0056] This method establishes a standard database to map product information, standard clauses, and standard items together. It then uses semantic matching to intelligently identify the standard items of the product to be certified, replacing manual retrieval and matching operations. This significantly shortens the time for standard matching and testing item sorting in the early stages of certification, reduces human error, and improves certification efficiency. At the same time, by combining production scale and historical data to determine testing parameters, the testing plan becomes more targeted, avoiding invalid testing and balancing certification accuracy and efficiency. This helps improve the overall efficiency of the certification process and strengthen data management.
[0057] In one possible embodiment, a vehicle authentication management method further includes: updating a standard database, specifically:
[0058] The system acquires the status information of vehicle standard documents, including at least one of revision, repeal, and new release. If the status information of a vehicle standard document changes, the standard database is updated, and the standard change history is recorded. For example, a standard update monitoring team is established to conduct weekly manual inspections of the official website, combining this with the system's automatic monitoring results to promptly identify standard update statuses. For updated standards, information extraction and database updates are performed again, and standard change notifications are pushed to relevant departments within the enterprise.
[0059] This method achieves automatic updating and dynamic management of vehicle standards by acquiring standard document status information in real time, dynamically updating the standard database, and recording change history. This helps enterprises keep abreast of standard developments and avoid certification failures or risks caused by outdated standards or missing information. At the same time, the standard change history is easy to trace, further improving the efficiency of standard management and providing a basic support for certification accuracy.
[0060] In one possible embodiment, a vehicle certification management method further includes: obtaining certification test reports of certified products, performing structured processing on the certification test reports and extracting first key information, and establishing a test report database based on the first key information; wherein the first key information includes the product model and the corresponding test information.
[0061] This method achieves unified collection and standardized management of test data by structuring the test reports of certified products, extracting the first key information, and establishing a test report database. This avoids the problems of messy and unreusable test reports, improves the traceability and reusability of test data, provides data support for subsequent test scheme optimization and the determination of deemed items, and strengthens data management capabilities, thus ensuring the traceability and certification process management of enterprise products.
[0062] In one possible embodiment, the first key information includes the product model, certification testing items, test results, and certification time.
[0063] This method, by clearly defining the specific content of the first key information (product model, certification testing items, test results, and certification time), makes the data in the test report database more complete and targeted, facilitating the rapid retrieval of historical data for the corresponding products and testing items, improving data retrieval and comparison efficiency, and providing more accurate data support for the reuse of historical test data, adjustment of test scheme parameters, and determination of deemed items.
[0064] In one possible embodiment, when the product to be certified is a new product, the second key information of the new product is obtained; the second key information is compared with the data in the test report database; if the similarity is greater than a preset threshold (e.g., 80%), it is determined to be a deemed item, and the test results of the corresponding certified item are obtained from the test report database; the second key information includes at least one of the following: vehicle type, body structure parameters (including size, weight and wheelbase, etc.), power type, drive type, tire specifications, and mandatory certified parts (including model manufacturers).
[0065] This method obtains the second key information of the new product and compares it with the similarity of historical data in the test report database to achieve intelligent determination of the same item. For the same item that meets the conditions, the test results of the certified item can be directly reused, which effectively avoids repeated testing, reduces the consumption of test samples and the investment of test time, improves the reuse rate of test data, and significantly reduces the certification and testing costs and time costs of enterprises.
[0066] In one possible embodiment, the number of tests and the number of samples for each certification testing item are determined based on the certification testing item list, combined with product production data and historical testing data, specifically as follows:
[0067] Pre-defined correspondence: A correspondence between production data and basic testing parameters is established in advance. The basic testing parameters include the number of benchmark tests and the number of benchmark samples for each certification testing item.
[0068] Obtain and match basic parameters: Obtain the actual production data of the product to be certified, and based on the correspondence between the production data and the basic testing parameters, match the benchmark number of tests and the benchmark sample quantity for each certification testing item of the product.
[0069] Retrieve and extract historical data: Retrieve historical test data for each certification test item corresponding to the product to be certified from the test report database, and extract historical test data items and data anomaly records.
[0070] Dynamically adjust detection parameters: If the similarity comparison of historical detection data is greater than or equal to the preset qualified threshold and there are no consecutive abnormal detection records, then the detection will be carried out according to a preset ratio based on the baseline number of detections and the baseline number of samples; if the similarity comparison of historical detection data is less than the preset qualified threshold, or there are consecutive abnormal detection records, then the number of detections will be increased according to a preset ratio based on the baseline number of detections and the baseline number of samples.
[0071] Determine and integrate the final solution: Based on the results of dynamic adjustments, determine the final number of tests and the number of samples for each certification testing item, and integrate these final parameters into the testing solution for this certification.
[0072] This application determines the basic testing parameters by combining product production data and dynamically adjusts the number of tests and samples based on historical testing data. This makes the testing plan more closely match the actual situation of the product, avoids certification risks caused by insufficient testing, and avoids cost waste caused by excessive testing. It not only ensures the accuracy and rigor of certification testing, but also achieves the rational allocation of testing resources, further reduces certification costs and improves certification efficiency. At the same time, it strengthens the value of data management by reusing historical data.

The test item matching module 3 matches corresponding certification test items from a pre-set certification test item knowledge base based on the identified standard items and forms a certification test item list. The certification test item knowledge base includes mapping relationships between standard items, certification test items, test methods, and test equipment. The test plan generation module 4, based on the certification test item list and combined with product production data and historical test data, determines the number of tests and sample quantities for each certification test item and generates a test plan for the product to be certified.
[0074] This system, through the collaborative efforts of its various modules, modularizes and automates the processes of standard database construction, intelligent standard item identification, test item matching, and test plan generation.
