[0043] In this embodiment, a method for automatically screening test data running on an electronic device is provided. Figure 1 is a flow chart of an automated test data screening method according to one embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0044] Step S10, performing a functional safety test on the target vehicle to obtain initial test data, wherein any initial test data in the initial test data corresponds to a test case, the test case is used to perform a functional safety test on any function of the target vehicle, and the initial test data is named based on a target naming rule, and the target naming rule includes the following rules: naming the test data based on the test case number;

[0045] In the embodiment of the present invention, the target vehicle can be understood as an autonomous driving vehicle, and the target vehicle can include an autonomous driving system, a lane keeping system, an adaptive cruise control system, etc., which are not limited here.

[0046] Functional safety testing of the target vehicle can be understood as testing the various systems and components of the target vehicle to ensure that the vehicle can maintain safety performance under normal use. For example, functional safety testing can be performed on the target vehicle's autonomous driving system, lane keeping system, adaptive cruise system, braking system, steering system, drive system, etc. Functional safety testing can also be performed on sensors, controllers, networks, etc. carried in the target vehicle to verify their reliability and safety under various circumstances, which is not limited here.

[0047] It is understandable that functional safety testing of the target vehicle can be carried out through various methods, such as field testing, simulation testing, virtual testing, etc., to ensure the safety performance of the vehicle on the road, which is not limited here.

[0048] Performing functional safety testing on the target vehicle can obtain initial test data, and the initial test data includes all data obtained when performing functional safety testing on the target vehicle. Exemplarily, the initial test data may include various sensor data of the target vehicle, such as environmental information and vehicle status information collected by sensors such as cameras, radars, and lidars. The initial test data may also include data from various controllers of the vehicle, such as the operating status, output signals, and other data of controllers such as engine controllers, brake controllers, and steering controllers. The initial test data may also include data transmitted between various modules inside the target vehicle through the vehicle network, such as data communications such as controller area networks (CAN) buses and Ethernet, which are not limited here.

[0049] Any of the initial test data corresponds to a test case, and the test case is used to perform a functional safety test on any function of the target vehicle. It is understandable that when performing a functional safety test on the target vehicle, the corresponding function of the target vehicle will be tested according to the pre-set test case, thereby obtaining test data corresponding to the test case.

[0050] It should be noted that when testing the corresponding functions of the target vehicle according to the test case, the test data may be inaccurate due to inaccurate settings of the control conditions or parameters of the test case. In this case, the control conditions or parameters of the test case will be adjusted again, and the test will be repeated according to the test case until accurate test data is obtained. Therefore, in the initial test data, the test data corresponding to the same test case may include multiple test data.

[0051] When the initial test data is obtained through testing, the initial test data will also be named based on the target naming rules. The target naming rules include the following rules: Name the test data based on the test case number. It is understandable that each test case corresponds to a test case number, and the initial test data will be named according to the corresponding test case number. For example, assuming that the test case number is TC001, the corresponding test data can be named TC001, which is not limited here.

[0052] In an embodiment of the present invention, initial test data is obtained by performing functional safety tests on a target vehicle, and the initial test data is named based on the corresponding test case number, so that the test case according to which the initial test data is obtained can be accurately located according to the naming of the initial test data, so that the data can be quickly and accurately screened subsequently.

[0053] Step S11, determining initial numbering information of initial test data, wherein the initial numbering information includes a test case number corresponding to any initial test data;

[0054] In an embodiment of the present invention, after obtaining the initial test data, it is necessary to determine the initial numbering information of the initial test data, the initial numbering information includes the test case number corresponding to any initial test data, that is, it is necessary to determine the test case number corresponding to each initial test data.

[0055] Exemplarily, since the initial test data is named based on the test case number, the initial numbering information of the initial test data can be accurately determined based on the file naming of the initial test data.

[0056] Step S12, screening the initial numbering information based on a first screening rule to obtain target numbering information, wherein the first screening rule screens according to the test case numbers, and the test case numbers in the target numbering information are different from each other;

[0057] In the embodiment of the present invention, the first screening rule is a screening rule for screening the initial numbering information, that is, screening the initial numbering information according to the test case number.

[0058] The initial numbering information is filtered based on the first filtering rule to obtain the target numbering information. It can be understood that after obtaining the initial numbering information, the initial numbering information needs to be filtered based on the first filtering rule to obtain the target numbering information, that is, the target numbering information is obtained after filtering the initial numbering information according to the first filtering rule.

[0059] It should be noted that, since the test data corresponding to the same test case in the initial test data may include multiple test data, that is, the same test case number may exist in the initial numbering information. Therefore, it is necessary to filter the initial numbering information through the first filtering rule to obtain the target numbering information. Moreover, the test case numbers in the target numbering information are different from each other, that is, the test case numbers in the target numbering information are unique.

[0060] Step S13, determining target test data based on the target number information.

[0061] In the embodiment of the present invention, after the target number information is obtained, the target test data is determined based on the target number information.

[0062] Exemplarily, the test case number in the target number information is unique, and based on the target number information, it can be quickly determined based on which test case the target test data is obtained, thereby saving time cost.

[0063] In an embodiment of the present invention, when screening test data, a functional safety test can be performed on a target vehicle to obtain initial test data, and the initial test data is named based on the test case number, so that the initial test data can be accurately located based on which test case the initial test data is obtained. Then, the initial numbering information corresponding to the initial test data is determined, and then the initial numbering information is screened based on the test case number to obtain the target numbering information, and finally the target test data is determined based on the target numbering information, so that the test case number in the target numbering information is unique, so that the target test data can be quickly determined based on which test case the target test data is obtained, saving time and cost, and thus avoiding omissions when screening and extracting test data, and avoiding errors and the like.

[0064] Through the above steps, the functional safety test is performed on the target vehicle to obtain the initial test data, wherein any initial test data in the initial test data corresponds to a test case, the test case is used to perform a functional safety test on any function of the target vehicle, and the initial test data is named based on the target naming rule, and the target naming rule includes the following rules: naming the test data based on the test case number; determining the initial numbering information of the initial test data, wherein the initial numbering information includes the test case number corresponding to any initial test data; filtering the initial numbering information based on the first screening rule to obtain the target numbering information, wherein the first screening rule is filtered according to the test case number, and the test case numbers in the target numbering information are different from each other; and determining the target test data based on the target numbering information. The purpose of automatically filtering the data based on the test case number is achieved, thereby reducing the test time cost and labor cost, while avoiding the occurrence of omissions, errors, etc. caused by manual screening and extraction of test data, and preventing the technical effect of affecting the subsequent steps, thereby solving the technical problem that the manual screening and extraction of test data in the related technology is not only time-consuming and labor-intensive but also prone to errors.

[0065] Optionally, in step S10, performing a functional safety test on the target vehicle to obtain initial test data may include the following execution steps:

[0066] Step S101, setting a target naming rule in a functional safety test system;

[0067] Step S102: Perform a functional safety test on the target vehicle based on the functional safety test system to obtain initial test data.

[0068] In the embodiment of the present invention, the functional safety test system can be understood as being used to test various systems of the target vehicle, to help evaluate the safety performance of the system, to discover potential problems and risks, and to make corresponding improvements and optimizations. For example, the functional safety test system can be used to simulate various possible dangerous situations and failure situations, and analyze the reaction and performance of the test system (including the braking system, steering system, vehicle stability control system, airbag system, etc.) when facing these situations, which is not limited here.

[0069] In an embodiment of the present invention, a functional safety test is performed on a target vehicle to obtain initial test data. The following steps can be performed: first, a target naming rule is pre-set in a functional safety test system; then, a functional safety test is performed on the target vehicle through the functional safety test system to obtain initial test data; and then, the initial test data is named based on the target naming rule, so that the initial test data can be accurately located according to the naming of the initial test data, so that the test data can be managed quickly and accurately subsequently.

[0070] Optionally, in step S11, determining the initial serial number information of the initial test data may include the following execution steps:

[0071] Step S111, determining a data naming file of the initial test data, wherein the data naming file is used to represent the data name of any initial test data;

[0072] Step S112, determining initial numbering information based on the data naming file.

[0073] In the embodiment of the present invention, the data naming file can be understood as a file named for any initial test data, and is composed of the file name of any initial test data. It can be understood that each data name of the initial test data is set with a corresponding data naming file.

[0074] Optionally, the initial test data may also be stored in a designated storage path. Exemplarily, the initial test data storage path may be, for example, "C: / ProgramData", which is not limited here.

[0075] Exemplarily, determining the initial numbering information of the initial test data can be achieved by executing the following steps. First, the data name of the initial test data is determined and made into a data naming file. Then, the initial numbering information of the initial test data is determined based on the data naming file. The use of the data naming file can improve the readability and comprehensibility of the data, thereby facilitating the management and analysis of the test data. The initial numbering information is used to facilitate the organization and screening of the initial test data obtained in subsequent testing work, thereby improving testing efficiency.

[0076] Optionally, in step S12, screening the initial numbering information based on the first screening rule to obtain the target numbering information may include the following execution steps:

[0077] Step S121, determining the naming times of any test case number in the initial numbering information, and obtaining naming times information;

[0078] Step S122, screening the initial numbering information based on the naming times information to obtain the target numbering information.

[0079] In the embodiment of the present invention, further, the first screening rule can be understood as a screening rule for screening the initial test data according to the naming number information.

[0080] The naming frequency information is used to record the naming frequency used for each test case number when naming the initial test data. It is understandable that since the same test case may correspond to multiple test data, there is more than one naming frequency information for the same test case number in the initial numbering information.

[0081] In an embodiment of the present invention, the initial numbering information is filtered based on the first filtering rule to obtain the target numbering information by executing the following steps: first, the number of times the same test case number in the initial numbering information is named is determined to obtain the naming number information; then, the initial numbering information is filtered based on the naming number information to obtain the target numbering information; the number of times the same test case number in the initial numbering information is named can help to better understand the importance and frequency of each test case, so that testing can be performed in a more targeted manner.

[0082] Optionally, the target naming rule further includes the following rule: the test data is named based on the test time. In step S122, the initial numbering information is screened based on the naming times information, and obtaining the target numbering information may include the following execution steps:

[0083] Step S1221, determining a first number in the initial numbering information based on the naming times information, wherein the first number is used to represent a test case number that is named once;

[0084] Step S1222, determining a second number in the initial numbering information based on the naming times information, wherein the second number is used to represent the number of the test case that has been named multiple times;

[0085] Step S1223, filtering the second number based on a second filtering rule to obtain a third number, wherein the second filtering rule filters according to a test time;

[0086] Step S1224, obtaining target number information based on the first number and the third number.

[0087] In an embodiment of the present invention, the target naming rule also includes the following rule: naming the test data based on the test time, which can be understood as the target naming rule for naming the initial test data includes two rules: naming the test data based on the test case number and naming the test data based on the test time. For example, assuming that the test case number is TC001 and the test time is October 15, 2022, the corresponding initial test data can be named TC001_October 15, 2022, which is not limited here.

[0088] A test case number named once can be understood as a test case number used only once when naming the initial test data, and it can be understood that the initial test data corresponding to the test case number named once is unique. A test case number named multiple times can be understood as a test case number used multiple times when naming the initial test data, and it can be understood that the initial test data corresponding to the test case number named multiple times is not unique.

[0089] Determining the first number in the initial numbering information based on the naming number information can be understood as using the naming number information to determine the test case number that is named once in the initial numbering information. Determining the second number in the initial numbering information based on the naming number information can be understood as using the naming number information to determine the test case number that is named multiple times in the initial numbering information.

[0090] The second screening rule can be understood as a rule for screening the second number based on the test time. It can be understood that since the second number is a test case number named multiple times, that is, the initial test data corresponding to the second number is not unique, there may be inaccurate initial test data. Therefore, the second number is screened by the second screening rule, so that the inaccurate initial test data corresponding to the second number is eliminated, and finally the third number is obtained, that is, the third number corresponding to the unique initial test data is obtained.

[0091] In an embodiment of the present invention, the initial numbering information is screened based on the naming number information to obtain the target numbering information, which can be achieved by executing the following steps: first, the naming number information is used to determine the test case number that is named once in the initial numbering information, then the test case number that is named multiple times in the initial numbering information is determined, and the second number is screened according to the test time to obtain the third number, and finally the target number information is obtained from the first number and the third number. The target numbering information obtained by filtering based on the naming number information can exclude some wrong or repeated numbers, thereby improving the accuracy and reliability of the data, and filtering the test data based on the test time can effectively filter out the latest test data, thereby better reflecting the safety performance of the current vehicle function, and the latest test data can often more accurately reflect the latest status of the vehicle function, so filtering based on the test time can improve the accuracy and reliability of the test results.

[0092] Optionally, in step S1223, filtering the second number based on the second filtering rule to obtain the third number may include the following execution steps:

[0093] Step S12231, determining the test data corresponding to the second number, and obtaining the problem test data;

[0094] Step S12232, determining initial time information of the problem test data, wherein the initial time information includes a test time corresponding to any problem test data in the problem test data;

[0095] Step S12233, classifying the initial time information based on the test case number to obtain at least one classification group, wherein any classification group corresponds to the same test case number;

[0096] Step S12234, filtering at least one classification group based on a third filtering rule to obtain target time information, wherein the third filtering rule filters according to the time interval between the test time and the current time;

[0097] Step S12235, determining a third number based on the target time information.

[0098] In the embodiment of the present invention, the problem test data can be understood as multiple test data corresponding to the same test case number. The third screening rule can be understood as a screening rule for screening at least one classification group according to the time interval between the test time and the current time.

[0099] Determine the initial time information of the problem test data, where the initial time information includes the test time corresponding to any problem test data in the problem test data, which can be understood as determining the initial test time of multiple test data corresponding to the same test case.

[0100] The initial time information is classified based on the test case number to obtain at least one classification group. Any classification group corresponds to the same test case number. It can be understood as classifying the initial time information of multiple test data corresponding to the same test case number, and then classifying the initial time of multiple test data corresponding to the same test case into the same classification group.

[0101] At least one classification group is screened based on the third screening rule to obtain target time information. The third screening rule is screened according to the time interval between the test time and the current time. It can be understood that at least one classification group is screened according to the time interval between the test time and the current time. Exemplarily, the initial time information with the smallest time interval with the current time in the same classification group is selected, that is, the test time closest to the current time is selected, and then the target time information is obtained.

[0102] Exemplarily, the second number is screened based on the second screening rule, and the third number can be obtained by executing the following steps. First, the corresponding problem test data can be obtained through the second number, and the test time corresponding to any problem test data in the problem test data is determined. Then, the initial time information of all problem test data is classified according to the test case number, and at least one test case number can be obtained. The same classification group corresponding to the same test case can be obtained. After classification, the test data corresponding to the same test case can be more easily identified, so that the test can be performed more efficiently. Then, at least one classification group is screened according to the time interval between the test time and the current time, and the target time information is obtained. Finally, the third number is determined using the obtained target time information. Screening test data through screening rules can improve the efficiency of the test, reduce the blindness and arbitrariness in the test process, so that problems can be found faster and repaired in time, ensuring that the functional safety performance of the vehicle meets the requirements.

[0103] Optionally, in step S12234, filtering at least one classification group based on the third filtering rule to obtain the target time information may include the following execution steps:

[0104] Step S122341, determining the initial time interval between any test time in any classification group and the current time;

[0105] Step S122342, determining a target time interval based on the initial time interval, wherein the target time interval is the time interval with the shortest interval length among the initial time intervals;

[0106] Step S122343, determining target time information based on the target time interval.

[0107] In the embodiment of the present invention, determining the initial time interval between any test time in any classification group and the current time can be understood as obtaining the current time, obtaining any test time in the selected classification group, and calculating the initial time interval between the current time and the selected test time.

[0108] The target time interval is determined based on the initial time interval. The target time interval is the time interval with the shortest interval length among the initial time intervals. It can be understood as selecting the test time closest to the current time.

[0109] Exemplarily, at least one classification group is screened based on the third screening rule, and the target time information can be obtained by executing the following steps: first, the current time is obtained, any test time in the selected classification group is obtained, the initial time interval between the current time and the selected test time is calculated, and then the time interval with the smallest interval length in the initial time interval is determined based on the initial time interval, and it is determined as the target time interval, and finally the target time interval is used to determine the target time information. At least one classification group is screened using the third screening rule, and the initial time information with the smallest time interval with the current time interval is used as the target time information, so that the test data obtained by screening are the latest, and the latest test data is more valuable than the old test data.

[0110] Optionally, the target naming rule also includes the following rules: naming the test data based on the project number, naming the test data based on the test function, and naming the test data based on the remark information.

[0111] As mentioned above, the target naming rule can name the test data based on the test case number and the test data based on the test time. In addition, the target naming rule can also name the test data based on the project number, the test data based on the test function, and the test data based on the remark information. For example, if the project number is PROJ001, the test function is the login function, the test case number is TC001, the test time is October 15, 2022, and the remark information is that the demand priority is high, then the corresponding test data can be named PROJ001_login_TC001_high_October 15, 2022, which is not limited here.

[0112] Figure 2 is a flow chart of a functional safety test according to one embodiment of the present invention. Figure 2As shown in the figure, when performing functional safety testing, it is first necessary to pre-customize the test data target naming rules in the functional safety test system. Then determine the initial test data storage path and perform functional safety testing on the target vehicle in the functional safety test system to obtain the initial test data. Then, according to the number of naming times of the test data naming file, the initial test data is filtered by traversal loop to obtain the target test data. Finally, the target test data is stored in the specified path and added to the set to be extracted.

[0113] Figure 3 This is a system schematic diagram of an automated test data screening method according to one embodiment of the present invention, including a path storage module, a test data screening module and a test data extraction module. The path storage module is used to save the storage path of the initial test data, and is also used to save the storage path of the target test data obtained after traversing and cyclically screening the initial test data. For example, the storage path of the initial test data may be in the form of "C: / ProgramData", and the storage path of the target test data may be in the form of "C: / ProgramData_Copy", which is not limited here. The test data screening module is used to filter all the initial test data under the initial test data storage path through a program algorithm and a target naming rule to obtain the target test data. The test data extraction module can extract the filtered target test data to a specified storage path through a program algorithm.
