[0049] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0050] In order to solve the problems of low processing efficiency and poor test quality in existing test data processing methods, embodiments of the present invention provide a test data processing method, apparatus, device, storage medium and program product.

[0051] like Figure 1 As shown, an embodiment of the present invention provides a test data processing method, including:

[0052] Step 101: Acquire test data and system functions of a vehicle control system.

[0053] That is, in this step, the test data of the vehicle control system is imported, which specifically includes: obtaining the format of the test data, the time of the test data, the collector of the test data, the size of the test data and the project to which the test data belongs.

[0054] The system function may also be referred to as a control function, and different system functions correspond to different control requirements and different control strategies.

[0055] Step 102: extract features from the test data to obtain test features of the test data.

[0056] In this step, by performing feature extraction on the test data, test features of the test data are obtained, and the test features can be used to subsequently verify whether the test data conforms to the system function.

[0057] Step 103: Classify the system functions to obtain system functions of different categories.

[0058] In this step, by classifying the system functions, it is convenient to verify the system functions using different test features later, thereby improving the verification efficiency.

[0059] Step 104: Verify different types of system functions using the test features to obtain verification results.

[0060] In this step, the test features are used to verify different system functions, which can conveniently verify the system functions, has a high input-output ratio, can well reuse test resources, save test time, and improve test efficiency.

[0061] In an optional embodiment, the test data analysis method includes at least one of the following: extracting features from the test data to obtain test features of the test data includes at least one of the following:

[0062] According to the preset control requirements (i.e., the control requirements mentioned above), the test data is feature extracted to obtain the test features corresponding to the preset control requirements in the test data, that is, the required test data can be quickly screened according to the conditions set by the control requirements, and the test data that meets the conditions is extracted to support the location and analysis of test problems. For example, the required torque output when the motor temperature is greater than 50°C and the accelerator pedal opening is greater than 50%, etc. Through data comparison and analysis, the required torque curves under different motor temperatures and different accelerator pedal openings can be quickly obtained, which is convenient for engineers to analyze the rationality and correctness of the required torque control logic;

[0063] Feature extraction is performed on the test data according to the control strategy of the system function to obtain the test features of whether the test data meets the control strategy. That is, when testing a specific control function, the compliance of the control strategy needs to be manually checked and verified. The accuracy of the verification is closely related to the technical level of the engineer, which will lead to inconsistency in the test. The test data can be batch processed to verify the function of the control strategy. The format of the control function definition can be a text description or a constraint or a table. For example, during the working condition torque verification test, the correctness of the required torque at different openings, different speeds, different motors and Insulate Gate Bipolar Transistor (IGBT) temperatures can be verified. The torque demand table is imported, and the test data is traversed by the program and verified with the specific data in the torque demand table to determine the compliance of the strategy;

[0064] The test data is feature extracted using the Controller Area Network (CAN) protocol to obtain test features corresponding to the fault information in the test data, that is, the CAN network protocol is imported to screen and analyze the message information in the fault message, and the fault information in the message is extracted: the time when the fault occurred and the relevant message information corresponding to the fault are recorded (the specific signal corresponding to each fault needs to be set in advance), and the changes in the relevant message information before and after the fault occurs are automatically identified, which is convenient for test engineers to locate the cause of the fault.

[0065] Further, feature extraction is performed on the test data according to the preset control requirement to obtain test features corresponding to the preset control requirement in the test data, including:

[0066] Obtaining a characteristic scenario in the preset control requirement;

[0067] Feature extraction is performed on the test data according to the feature scenario to obtain test features corresponding to the feature scenario in the test data.

[0068] Specifically, when designing control functions, sometimes some function designs may not take into account user habits or scenarios, which may lead to inconvenience or failure of the functions. Import test data into the system, decompose the control requirements into specific items and import them into the system, check whether there are feature scenarios not included in the control requirements, and extract the specific information in these scenarios for the optimization of the control strategy in the later stage.

[0069] In an optional embodiment, the system functions are classified to obtain different types of system functions, including:

[0070] Obtaining the importance of the system function according to the functional impact of the system function;

[0071] Among them, system functions of different importance correspond to different categories of system functions;

[0072] The functional impact includes at least one of the following:

[0073] It affects the safety of the entire vehicle, the driving experience, and the feelings of the driver and passengers.

[0074] It should be noted that the vehicle control system includes many system functions. The importance (or priority) of the system functions is strongly related to the safety of the entire vehicle, driving experience, and personnel perception. Therefore, when using the same test data to verify the control strategies of different system functions, different choices need to be made based on the importance of the system functions.

[0075] Among them, the importance of system functions is defined as follows:

[0076] System functions that affect the safety of the entire vehicle are important; system functions that affect the driving experience are severe or moderate; and system functions that cannot be directly felt by the driver and passengers are mild.

[0077] In an optional embodiment, the test features are used to perform verification for different types of system functions to obtain verification results, including:

[0078] Obtain key statements of the test case of the system function, wherein the key statements may include one or more of a threshold class, a condition class, a delay trigger class, and a fault trigger class branch class;

[0079] The key sentences corresponding to the system functions of different categories are verified using the test features to obtain verification results.

[0080] That is, the key statements of the system functions are classified, and different test features are called for verification for key statements of different categories to obtain verification results.

[0081] It should be noted that in this embodiment, the key statements are verified using the test features to obtain the verification results, and verification can also be performed in combination with the above-mentioned importance levels, that is, the key statements corresponding to the system functions of different categories are verified using the test features to obtain the verification results, including:

[0082] The test features are used to verify key statements corresponding to system functions of different importance to obtain verification results.

[0083] Furthermore, the key statements corresponding to the system functions of different categories are verified using the test features to obtain verification results, including at least one of the following:

[0084] The threshold information in the key sentences corresponding to the system functions of different categories is verified using the test features to obtain a verification result.

[0085] Specifically, the key statement of the system function is A≤X≤B, and the principle of extracting test data is to extract according to the threshold information (A, B), and verify whether the test data meets the key statement. It is also possible to combine the importance and threshold information, set the threshold boundary, extract the test data according to the threshold boundary and threshold information, obtain the corresponding test features, and determine whether the test data meets the control requirements corresponding to the system function according to the corresponding test features for verification. Exemplarily, the extraction principle is as shown in Table 1 below:

[0086] Table 1

[0087]

[0088] The precision value can be selected according to the requirements, and the middle value is equal to (A+B) / 2.

[0089] For example, the control requirement corresponding to the system function is: when the motor temperature is greater than 200°C, the output of the required torque is limited.

[0090] The trigger condition information in the key statements corresponding to different categories of the system functions is verified using the test features to obtain verification results, wherein the trigger condition information includes at least one of the following: conditions and information, conditions or information, conditions and information can be understood as satisfying condition 1 & condition 2 & condition 3 to achieve this system function, and conditions or information can be understood as satisfying condition 1 || condition 2 || condition 3 to achieve this system function.

[0091] Specifically, when the trigger condition information is a condition and information, the extraction and verification principles adopted by the importance of the system function are the same, both of which are Modified Condition / Decision Coverage (MCDC). The extraction method and expected verification results are shown in Table 2 below:

[0092] Table 2

[0093] Condition 1 Condition 2 Condition 3 Expected Results T T T Establishment T T F Not established T F T Not established F T T Not established

[0094] Among them, "T" means the condition is met, and "F" means the condition is not met.

[0095] For example, the control requirements corresponding to the system function are: the vehicle jumps from the initial state to the torque output state when any of the following conditions is met: 1) the KL15 wake-up signal is 1; 2) the vehicle READY signal is 1; 3) the vehicle's maximum output torque is greater than 5.

[0096] Specifically, when the trigger condition information is a conditional OR information, the extraction and verification principles for the importance level of the system function are the same, both being MCDC. The extraction method and the expected verification results are shown in Table 3 below:

[0097] Table 3

[0098] Condition 1 Condition 2 Condition 3 Expected Results T F F Establishment F T F Establishment F F T Establishment F F F Not established

[0099] Among them, "T" indicates that the condition is satisfied, and "F" indicates that the condition is not satisfied.

[0100] For example, the control requirement corresponding to the system function is that when one of the following conditions is met, the vehicle jumps from the sleep state to the power-on state: 1) The KL15 wake-up signal is 1; 2) The slow charge wake-up signal is 1; 3) The remote wake-up signal is 1.

[0101] When the trigger condition information is conditional AND information and conditional OR information, an example of the system requirement is to satisfy the condition 1 && (condition 2 || condition 3) && condition 4 to implement this function. The extraction and verification principles for the importance level of the system function are the same, both being MCDC.

[0102] For the delayed trigger information in the key statements corresponding to different categories of the system functions, the test features are used for verification to obtain the verification results.

[0103] It can be understood that the control requirement corresponding to the system function is that the duration of a certain condition is greater than the preset duration. To implement this system function, the extraction principle of the test data sets the number of boundary values according to the importance level of the system function, and verifies the compliance of the test data with the requirements.

[0104] Exemplarily, the key statement of the system requirement is to satisfy some single conditions or condition combinations (such as condition 1) and the duration >= T1 to implement this system function. The extraction principle of the data sets the number of boundary values according to the importance level of the system function, and verifies the compliance of the test data with the requirements. The extraction principles are as follows:

[0105] 1. Satisfy condition 1 and the duration < T1, and this system function is not implemented.

[0106] 2. Do not satisfy condition 1, and the duration >= T1, and this system function is not implemented.

[0107] 3. Satisfy condition 1, and the duration < T1, and this system function is not implemented. Verify whether the time counter is cleared.

[0108] 4. Satisfy condition 1, and the duration >= T1, and this system function is implemented.

[0109] For example, the control requirement corresponding to the system function is: when the temperature of the motor controller is greater than 200°C, the motor output torque is limited to 0 after a delay of 8 seconds.

[0110] The fault triggering information in the key sentences corresponding to the system functions of different categories is verified using the test features to obtain a verification result.

[0111] Exemplarily, the key statement of the control requirement corresponding to the system function is that if condition 1 is met, a fault is triggered, a test feature is extracted from the test data, and verification is performed using the test feature to obtain a verification result.

[0112] Specifically, the key statement of the control requirement corresponding to the system function is that if condition 1 is met, a fault is triggered. The data extraction principle sets the number of extraction boundary values ​​according to the importance of the system function, and verifies the compliance of the test data with the requirements. The extraction principle is as follows:

[0113] 1. Condition 1 is not met and the fault phenomenon is not triggered;

[0114] 2. Condition 1 is met, triggering the fault phenomenon;

[0115] 3. Restore the fault and test whether the phenomenon exists according to the functional definition;

[0116] 4. If condition 1 is met again, the fault is triggered;

[0117] For example, the control requirement corresponding to the system function is: the motor speed exceeds the motor overspeed limit value of 15000 rpm for a specified time of 0.1S continuously.

[0118] The state jump information in the key statements corresponding to the system functions of different categories is verified using the test features to obtain a verification result.

[0119] Exemplarily, the key statement of the control requirement corresponding to the system function is to perform a state jump when the condition is met, extract test features from the test data, and perform verification using the test features to obtain a verification result.

[0120] Specifically, the key statement of the control requirement corresponding to the system function is to jump to the state when the condition is met. The data extraction principle sets the number of extraction boundary values ​​according to the importance of the system function, and verifies the compliance of the test data with the requirements. The extraction principle is as follows:

[0121] 1. Add all transitions and states to the tree according to the state transition method.

[0122] 2. Test the conditions for state transition.

[0123] 3. Test each branch.

[0124] For example, the control requirement corresponding to the system function is: the motor speed exceeds the motor overspeed limit value of 15000 rpm for a specified time of 0.1S continuously.

[0125] It should be noted that the information in the above key sentences can be obtained by selecting one or more combinations thereof, and the combined information can be verified using the test features to obtain a verification result.

[0126] Furthermore, after performing verification using the test feature and obtaining a verification result, the method further includes:

[0127] In the case that the verification result does not meet the preset test requirement, a test report is generated according to the test data corresponding to the verification result that does not meet the preset test requirement.

[0128] That is, by using the above steps, the system test requirements are classified according to different functional types and functional priorities, and different verification methods are selected to verify the test data according to different requirement types. If it is found that the test results are inconsistent with the control strategy (that is, the preset test requirements), the specific information and phenomena of the inconsistency (that is, how the preset test requirements are not met) are extracted (the extraction of fault information is completed automatically, and the extracted information includes the problem time, data collector, key signals, content inconsistent with the requirements, etc.), and the test problem needs to be reported after confirmation by the control engineer.

[0129] After the test problem is reported, the test data is archived and sent to the development engineer, and the development engineer is reminded to complete the problem closure. After the development engineer completes the problem rectification, the test engineer verifies the test problem and verifies the rationality of the control strategy again to ensure that all test problems are closed.

[0130] Combine the following Figure 2 , specifically describe the specific process of the test data processing method provided by the embodiment of the present invention:

[0131] Data import: obtain test data and system functions;

[0132] Test data analysis: extracting features from the test data to obtain test features of the test data, including:

[0133] (1) Data extraction and comparison: extracting features from the test data according to preset control requirements to obtain test features corresponding to the preset control requirements in the test data;

[0134] (2) Requirement algorithm verification: extracting features from the test data according to the control strategy of the system function to obtain test features of whether the test data meets the control strategy;

[0135] (3) Fault message analysis: extracting features from the test data using the Controller Area Network (CAN) protocol to obtain test features corresponding to the fault information in the test data;

[0136] (4) Feature scenario analysis: extracting features from the test data according to the feature scenario to obtain test features corresponding to the feature scenario in the test data.

[0137] System function classification: according to the functional impact of the system function, the importance of the system function is obtained; wherein, system functions of different importance correspond to different categories of system functions.

[0138] Obtain key statements of the test case of the system function;

[0139] The key statements corresponding to the system functions of different categories are verified using the test features to obtain verification results, including:

[0140] (1) Threshold category: for the threshold information in the key sentences corresponding to the system functions of different categories, the test features are used to perform verification to obtain verification results;

[0141] (2) Trigger condition category: for trigger condition information in the key sentences corresponding to different categories of the system functions, the test features are used to perform verification to obtain verification results;

[0143] (4) Fault trigger category: for the fault trigger information in the key sentences corresponding to the system functions of different categories, the test features are used to perform verification to obtain verification results;

[0144] (5) Branch category: The state jump information in the key statements corresponding to different categories of the system functions is verified using the test features to obtain verification results.

[0145] Reporting of test issues: If it is found that the test results are inconsistent with the control strategy (i.e., the preset test requirements), the specific information and phenomena of the inconsistency (i.e., how the preset test requirements are not met) will be extracted (the extraction of fault information is completed automatically, and the extracted information includes the problem time, data collector, key signals, content inconsistent with the requirements, etc.), and the test problem will be reported after confirmation by the control engineer.

[0146] Test problem closure and test data archiving: After the test problem is reported, the test data is archived and sent to the development engineer, and the development engineer is reminded to complete the problem closure. After the development engineer completes the problem rectification, the test engineer verifies the test problem and verifies the rationality of the control strategy again to ensure that all test problems are closed.

[0147] The following is a specific example to illustrate the specific implementation of the present invention:

[0148] System application description:

[0149] According to the above process, the data collected during the vehicle test is verified and test problems or optimization suggestions are reported based on the test verification results.

[0150] System function: energy recovery function.

[0151] Control requirements of system functions: Under the D-gear coasting energy recovery condition, if the energy recovery gear is 1, the energy recovery torque is related to the motor speed. The required torque is looked up in a one-dimensional table based on the motor speed, and the motor speed and corresponding torque table are selected based on whether there is creep.

[0152] Test data analysis: Required algorithm verification is required.

[0153] Importance of the control system function: This function affects the safety of the entire vehicle, so the importance of the function is heavy.

[0154] Validated Strategy Classification: The torque table is presented as a threshold class.

[0155] Verification purpose: According to the importance of system functions and the verification strategy classification, verify the torque table under the D gear coasting energy recovery condition, the energy recovery gear is 1, and the motor speed range is between 500rpm and 2000rpm. The details of the torque table are shown in Table 4 below:

[0156] Table 4

[0157] Speed 0 100 500 2000 2250 2750 3250 3500 4000 5000 6000 7000 Torque 0 -10 -20 -30 -40 -40 -40 -40 -40 -30 -20 -10

[0158] Threshold values: According to the system importance classification, the motor speed values ​​are: 499.9 (minimum accuracy is 0.1), 500, 500.1, 1000, 1999.9, 2000, 2000.1, 2200 and 400.

[0159] Torque value verification: According to the above motor speed value, the matching test data is extracted from the test data, and the expected torque value is verified with the actual torque value. The control strategy can be quickly verified using the actual vehicle test data.

[0160] Through the verification of the above scenarios, it can be determined that this patent can easily verify the control strategy, has a high input-output ratio, can reuse test resources well, and save test time.

[0161] The embodiment of the present invention provides a method for processing test data at a certain point, which can process the test data and perform secondary processing on the test data, extract the corresponding test data to verify the correctness and rationality of the control strategy, and the corresponding test scenario can be used for later strategy development. It can automatically analyze the test data and verify the accuracy of the control strategy based on the selected test data, which reduces the workload of the test project and can effectively improve the processing efficiency of the automobile test data, ensuring the quality of the control system software test. It verifies the correctness of the control strategy for the control requirements corresponding to the system functions.
