[0026] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation of the present application.

[0027] The expected functional safety automated audit method, system, electronic device, storage medium and program of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0028] Specifically, Figure 1 is a schematic flow chart of an expected functional safety automated audit method provided by an embodiment of the present application.

[0029] As Figure 1 shown, the expected functional safety automated audit method includes the following steps:

[0030] In step S101, the file name and text content of at least one target functional safety file are obtained.

[0031] Among them, the target functional safety files include enterprise capability-related files and product development-related files, and no specific limitations are made.

[0032] It can be understood that the embodiments of the present application can obtain the file name and text content of at least one target functional safety file, so as to subsequently audit the file name of the target functional safety file using the first target keyword and audit the text content of the target functional safety file using the second target keyword.

[0033] It should be noted that the present application supports the import of multiple file formats. For example, the multiple file formats are:.txt,.xls,.xlsx,.doc,.docx,.jpg,.png,.gif,.pdf format files.

[0034] Specifically, as Figure 2 shown, the content of the expected functional safety automated audit proposed by the present application is divided into two major parts, namely the enterprise capability part and the product technology part; the audit objectives of each part also include file integrity, content integrity and unity.

[0035] The enterprise capability-related files of the present application are mainly the files related to the expected functional safety process system of the enterprise; the product technology-related files are mainly the files related to the expected functional safety development of the autonomous driving system; in addition, the present application can import one or more target functional safety files, and by automatically extracting the file name and text content of the target functional safety files, the entire audit cycle can be greatly shortened and the audit efficiency can be improved.

[0036] In step S102, the file names of the target functional safety files are audited by calling all the first target keywords in the functional safety database to generate the audit results of the file names.

[0037] It can be understood that the embodiments of the present application can call the file names of all the first target keywords in the functional safety database to audit the file names of the target functional safety files. By keyword matching, the consistency and accuracy of the file names are ensured, and the integrity of the target functional safety files and whether they meet the requirements of the expected functional safety standards can be clarified, reducing the subjective judgment errors that may be brought by manual auditing and improving the auditing efficiency.

[0038] In the embodiments of the present application, generating the audit results of the file names by auditing the file names of the target functional safety files according to the first target keywords includes: using each first target keyword as an index to query the file names of the target functional safety files; if each first target keyword does not match the file name of the target functional safety file, the audit of the file name of the target functional safety file fails; if there is at least one first target keyword that matches the file name of the target functional safety file, identify all the first target keywords that have not been successfully matched; if each first target keyword matches at least one file name, the audit of the file name is successful.

[0039] It can be understood that the embodiments of the present application match each first target keyword with the file names of each target functional safety file one by one, clarify the integrity of the target functional safety files according to the matching results, and the automated auditing can quickly process a large number of files, improving the auditing efficiency to ensure that all file names meet the requirements of the expected functional safety, and improving the overall safety and reliability of the product.

[0040] Specifically, the functional safety database of the embodiments of the present application includes a first preset table and a second preset table. The first preset table is mainly the enterprise ability files and examples of audit points, as shown in Table 1 below. The second preset table is mainly the product development files and examples of audit points, as shown in Table 2 below.

[0041] It should be noted that the first target keywords of the embodiments of the present application correspond to the file integrity audit keywords in the first preset table and the second preset table, and the first preset table and the second preset table can be set according to actual needs without specific limitations.

[0042] Table 1 Examples of enterprise ability files and audit points

[0045]

[0046] Table 2 Example of Product Development Documents and Key Points for Review

[0047]

[0048]

[0049] In the embodiment of the present application, after identifying all the first target keywords that do not match successfully, it includes: using all the first target keywords that do not match successfully as an index to query the functional safety database to obtain the corresponding file names; generating a list of missing file names according to the file names corresponding to all the first target keywords that do not match successfully.

[0050] It can be understood that in the embodiment of the present application, using all the first target keywords that do not match successfully as an index to query the functional safety database to obtain the corresponding file names; generating a list of missing file names according to the file names corresponding to all the first target keywords that do not match successfully, so as to determine the list of missing file names for the files imported this time, which helps the development team clarify which files need to be supplemented, not only improving the review efficiency, but also ensuring the consistency of the review results between different batches.

[0051] Specifically, as Figure 3 shown, after the file name matching of the target functional safety file is completed, determine all the first target keywords that do not match successfully, and query the first preset table according to the first target keywords to generate the corresponding missing file names as shown in Table 1 above.

[0052] For example, after the file name matching of the target functional safety file is completed, the determined first target keywords that do not match successfully are "safety plan" and "distributed development". By looking up Table 1 above, it is determined that the corresponding list of missing file names is: safety plan and distributed development management.

[0053] In step S103, if the file name review of at least one target functional safety file is successful, then determine at least one second target keyword according to the first target keyword corresponding to the file name of the target functional safety file with a successful review, and review the text content of the target functional safety file according to each second target keyword to generate the review result of the text content.

[0054] It is understandable that if the file name review of at least one target functional safety file in the embodiments of the present application is successful, at least one second target keyword is determined according to the first target keyword corresponding to the file name of the target functional safety file with successful review. The text content of the target functional safety file is reviewed according to each second target keyword to generate a review result of the text content, and the integrity of the technical key points in the target functional safety file is clarified, so as to further review the missing items in the text content of the target functional safety file, help the development team improve the document content, and thus ensure that both the file name and the text content of the target functional safety file meet the requirements of the expected functional safety.

[0055] For example, if the file name reviews of multiple target functional safety files are successful, the corresponding first target keywords are: "management process" and "safety plan". Then, according to the first target keywords, the first preset table is queried. As shown in Table 1 above, the second target keywords are determined to be: "expected functional safety regulations", "expected functional safety processes", "version management", "personnel and responsibilities", "deliverable requirements", and the purpose, preconditions, outputs, responsible persons, start time, end time, and status of safety activities.

[0056] In the embodiments of the present application, the text content of the target functional safety file is reviewed according to each second target keyword to generate a review result of the text content, including: querying the text content of the target functional safety file with each second target keyword as an index; if the text content contains each second target keyword, the text content review is successful; if the text content does not completely contain each second target keyword, the text content review fails.

[0057] It is understandable that in the embodiments of the present application, the text content of the target functional safety file is queried with each second target keyword as an index; if the text content contains each second target keyword, the text content review is successful; if the text content does not completely contain each second target keyword, the text content review fails, so as to comprehensively check whether the text content meets the requirements of the expected functional safety, ensure the consistency of the review criteria between different files, avoid differences caused by human factors, and improve the stability and consistency of the review.

[0058] Specifically, as Figure 3 shown, it is to query whether the text content of the target functional safety file includes all keywords according to the second target keyword. For example, if the text content of the target functional safety file contains "expected functional safety regulations", "expected functional safety processes", "version management", "personnel and responsibilities", but lacks "deliverable requirements", then the content review fails.

[0059] In the embodiment of the present application, after the text content review fails, it includes: identifying a second target keyword not included in the text content; generating a missing keyword list based on the second target keyword not included in the text content.

[0060] It can be understood that the embodiment of the present application can identify the second target keyword not included in the text content; generate a missing keyword list based on the second target keyword not included in the text content, thereby providing specific improvement suggestions for the development team to help them improve the document content, ensure that all necessary information is covered, and ensure that both the file name and text content of the target functional safety file meet the requirements of the expected functional safety.

[0061] In step S104, the review result of the target functional safety file is generated according to the review result of the file name and the review result of the text content.

[0062] It can be understood that the embodiment of the present application can generate the review result of the target functional safety file according to the review result of the file name and the review result of the text content, and conduct a comprehensive and efficient review and evaluation of the target functional safety file through automated means, which not only improves the review efficiency and accuracy, but also ensures the unified implementation of the review criteria and improves the stability of the review.

[0063] In the embodiment of the present application, generating the review result of the target functional safety file according to the review result of the file name and the review result of the text content includes: if the review results of both the file name and the text content are successful, outputting a completeness review report of the target functional safety file; if the review of the file name fails and / or the review of the text content fails, outputting a corresponding review report according to the missing file name list and / or the missing keyword list of the target functional safety file.

[0064] It can be understood that in the embodiment of the present application, if the review results of both the file name and the text content are successful, a completeness review report of the target functional safety file is output; if the review of the file name fails and / or the review of the text content fails, a corresponding review report is output according to the missing file name list and / or the missing keyword list of the target functional safety file, thereby providing specific improvement suggestions for the development team to help them improve the document content, ensure that all necessary information is covered, and ensure that both the file name and text content of the target functional safety file meet the requirements of the expected functional safety.

[0065] According to the expected functional safety automated auditing method proposed by the embodiments of the present application, all first target keywords in the functional safety database are called to audit the file name of the target functional safety file to generate the audit result of the file name. If the file name audit of at least one target functional safety file is successful, at least one second target keyword is determined according to the first target keyword corresponding to the file name of the successfully audited target functional safety file, and the text content of the target functional safety file is audited according to each second target keyword to generate the audit result of the text content. The audit result of the target functional safety file is generated according to the audit result of the file name and the audit result of the text content, and the target functional safety file is comprehensively and efficiently audited and evaluated by automated means, and the integrity of the target functional safety file and the integrity of the corresponding technical points in the file are audited according to the first target keyword and the second target keyword, so as to help the development team clarify which files and the text content corresponding to the technical points need to be supplemented, which not only improves the audit efficiency, but also improves the stability, accuracy and consistency of the audit, and at the same time can ensure the unified implementation of the audit standard to ensure that the enterprise system meets the requirements of the expected functional safety standard in the processes of design, verification and validation, etc.

[0066] Next, the expected functional safety automated auditing system proposed by the embodiments of the present application is described with reference to the accompanying drawings.

[0067] Figure 4 It is a block diagram of the expected functional safety automated auditing system of the embodiments of the present application.

[0068] As Figure 4 shown, the expected functional safety automated auditing system 10 includes: a file import module 100, a rule editing module 200, a problem identification module 300, and a report generation module 400.

[0069] Among them, the file import module 100 is used to import at least one target functional safety file into the rule editing module; the rule editing module 200 is used to calibrate the corresponding functional safety database according to the type of the target functional safety file, where the functional safety database includes a first preset table and a second preset table; the problem identification module 300 is used to call all first target keywords in the functional safety database to audit the file name of the target functional safety file to generate an audit result of the file name; if the file names of at least one target functional safety file are successfully audited, at least one second target keyword is determined according to the first target keyword corresponding to the file name of the successfully audited target functional safety file, and the text content of the target functional safety file is audited according to each second target keyword to generate an audit result of the text content; an audit result of the target functional safety file is generated according to the audit result of the file name and the audit result of the text content; the report generation module 400 is used to generate an evaluation audit report according to the audit result of the target functional safety file output by the problem identification module.

[0070] It should be noted that the foregoing explanation of the embodiments of the expected functional safety automated audit method is also applicable to the expected functional safety automated audit system of this embodiment, and will not be elaborated here.

[0071] According to the expected functional safety automated audit system proposed in the embodiments of the present application, all first target keywords in the functional safety database are called to audit the file name of the target functional safety file to generate an audit result of the file name; if the file names of at least one target functional safety file are successfully audited, at least one second target keyword is determined according to the first target keyword corresponding to the file name of the successfully audited target functional safety file, and the text content of the target functional safety file is audited according to each second target keyword to generate an audit result of the text content; an audit result of the target functional safety file is generated according to the audit result of the file name and the audit result of the text content, and the target functional safety file is comprehensively and efficiently audited and evaluated by automated means, and the integrity of the target functional safety file and the integrity of the corresponding technical points in the file are audited according to the first target keyword and the second target keyword, so as to help the development team clarify which files and the text content corresponding to the technical points need to be supplemented, which not only improves the audit efficiency, but also improves the stability, accuracy and consistency of the audit, and at the same time can ensure the unified implementation of the audit standard to ensure that the enterprise system meets the requirements of the expected functional safety standard in the processes of design, verification and validation.

[0072] Next, Figure 5 The expected functional safety automated audit system and method of the present application will be elaborated in detail as follows:

[0073] In view of the problems and deficiencies of manual review, this application provides an automated review system for expected functional safety, which comprehensively and efficiently reviews and evaluates the enterprise's expected functional safety process system and the expected functional safety development process of the autonomous driving system through automated means, ensuring that the system meets the requirements of the SOTIF standard during the processes of design, verification, and validation. Among them, the automated review system for expected functional safety is equivalent to an automated review and evaluation tool for expected functional safety.

[0074] First of all, the content reviewed by the automated review and evaluation system for expected functional safety proposed in this application is divided into two major parts, namely the enterprise ability part and the product technology part. The review objectives of each part also include document integrity, content integrity, and unity.

[0075] Among them, the enterprise ability part reviews whether the enterprise's expected functional safety process system is perfect, while product technology focuses on the documents related to the expected functional safety development of the autonomous driving system. When reviewing, first check whether the relevant documents that should be included are present to complete the review of document integrity; secondly, check whether the documents contain the necessary content to complete the review of content integrity.

[0076] The automated review tools mainly adopted by the automated review system for expected functional safety include a file import module, a rule editing module, a problem identification module, and a report generation module. Specifically:

[0077] (1) File import module

[0078] Supports the import of files in the formats of.txt,.xls,.xlsx,.doc,.docx,.jpg,.png,.gif,.pdf.

[0079] (2) Rule editing module

[0080] In the rule editing module, set the target text file name and the keywords in the file content for rule setting.

[0081] The following Table 1 and Table 2 are respectively examples of the content included in the enterprise ability part and the product technology part, which can be set according to requirements and are not specifically limited.

[0085]

[0086] Table 2 Examples of product development files and review key points

[0087]

[0088] (3) Problem identification module (such as Figure 3 )

[0089] First, conduct a file integrity review process on the submitted materials; according to the expected functional safety process system and the list of critical file names required for product development, such as "Specification Definition and Design Template", "Hazard Analysis and Risk Assessment Guidebook", "Change Management", etc., the system automatically extracts the file names from the uploaded files and matches them with the preset keyword list (Table 1 or Table 2 above), and outputs the corresponding missing file names in the problem record section for the matched files.

[0090] Secondly, conduct a review of content integrity, delve into the interior of the document, and conduct a detailed keyword retrieval review on key elements such as chapter titles and body content according to the expected functional safety development requirements. Taking the product hazard analysis and risk assessment work as an example, keywords such as "Design Operating Range", "Task Privilege Level", "SOTIF Strategy at the Vehicle Level", etc. will be used to accurately retrieve and compare the relevant content in the document, and output the missing key points.

[0091] (4) Report generation module

[0092] The report generation module presents all the missing items identified in the file integrity and content integrity during the review process, forms a list of files not provided or not meeting the requirements, and the missing situation of key development content (such as risk assessment, verification test report, etc.), ensuring the accuracy of the review results and providing a basis for subsequent improvement.

[0093] In summary, this application conducts a review and evaluation of the expected functional safety process system and product development by automatically comparing and retrieving the keyword list, significantly improving the efficiency of the review and evaluation, reducing the time and cost of manual operations, and at the same time, reducing errors and omissions caused by human factors.
