[0028] Local Interconnect Network (LIN) communication is a low-cost, single-wire transmission, highly flexible, and stable transmission serial communication network, mainly used for electronic devices such as automotive doors and windows, seats, sensors, and steering wheels that have low requirements for real-time performance and transmission speed but are cost-sensitive.

[0029] Currently, there are many electronic and electrical components involved in communication inside the existing body domain controller, with frequent signal interactions, an increasing amount of test content, and frequent operations during the test process. The method of manually testing electronic devices that need to write configuration words still has the problem of low efficiency.

[0030] An embodiment of the present application provides a testing method, which can be executed by a processor of a computer device. Herein, the computer device may refer to a device with data processing capabilities such as a server, a laptop computer, a tablet computer, a desktop computer, a smart TV, a set-top box, a mobile device (such as a mobile phone, a portable video player, a personal digital assistant, a dedicated messaging device, a portable gaming device), a testing tool, etc.

[0031] Figure 1 FIG. is a schematic flow chart of the implementation of a testing method provided by an embodiment of the present application, and this method can be executed by a processor of a computer device. As Figure 1 shown, this method includes the following steps S101 to step S104, which will be described in combination with Figure 1 the steps presented.

[0032] Step S101: Send a first control signal for setting a first configuration word to the controller under test.

[0033] Wherein, the first configuration word cannot adjust the first function of the controller under test.

[0034] In some embodiments, the controller under test may be an Electronic Control Unit (ECU).

[0035] In some embodiments, a configuration word is a set of parameters or instructions used to control the working modes, different functions, and interactions with other systems of different devices through the controller under test. By modifying the configuration word, the operating parameters of the device can be adjusted; for example, the electronic control unit adjusts the vehicle seat temperature, window lifting and lowering, air suspension working mode, etc. through the configuration word.

[0036] In some embodiments, after receiving the configuration word, the controller under test usually stores the configuration word in a non-volatile memory, such as an Electrically Erasable Programmable Read-Only Memory (EEPROM) or a Flash memory, etc.

[0037] In some embodiments, the first control signal may be a Local Interconnect Network (LIN) signal, a Controller Area Network (CAN) signal, etc. The configuration word stored in the controller under test can be modified through the first configuration word carried in the first control signal, and the working parameters or working modes of different devices or functions of the vehicle can be controlled through the first configuration word. Wherein, if the first control signal is a LIN signal, the first configuration word is written into the data segment of the LIN signal, and the LIN signal with the first configuration word written is sent to the controller under test.

[0038] In some embodiments, the first function may be a seat heating function, an air suspension function, a window lifting function, etc.

[0039] In some embodiments, a first control signal for setting a first configuration word is sent to the controller under test to modify the configuration word stored in the controller under test to the first configuration word, so that based on the control strategy of the first configuration word, the working mode or working parameters of the vehicle device are controlled by the controller under test.

[0040] Exemplarily, the binary number of the configuration word pre-stored in the controller under test is 01000000, indicating that the vehicle seat temperature is adjusted to a low temperature, and the binary number of the first configuration word is 00000000, indicating that the seat temperature is not controlled. Thus, the configuration word pre-stored in the controller under test is replaced with the first configuration word in the first control signal to adjust the strategy of controlling the seat temperature adjustment to a low temperature by the controller under test to not controlling the seat temperature.

[0041] Step S102: Receive first response data sent by the controller under test in response to the first control signal.

[0042] In some embodiments, the first response data may be data such as status information, confirmation information, and fault codes that can reflect the result of writing the first configuration word and the current state of the controller under test.

[0043] In some embodiments, after receiving the first control signal for setting the first configuration word, the controller under test parses the first control signal, saves the obtained first configuration word, generates first response data after controlling the target device of the vehicle based on the control instruction or parameter corresponding to the first configuration word, and sends the first response data.

[0044] Exemplarily, after sending a LIN control signal for setting the first configuration word to the electronic control unit, the electronic control unit parses the LIN control signal and obtains that the content of the first configuration word is 00000000, that is, the first configuration word represents not adjusting the first function or the parameters of the electronic control unit; the electronic control unit does not currently generate fault information related to the first configuration word, so the current fault code generated by the electronic control unit is the fault code at the historical moment; thus, the fault code at the historical moment sent by the electronic control unit in response to the first control signal for setting the first configuration word is received.

[0045] Step S103: When the first response data is the same as the first preset response data, send a second control signal for setting a second configuration word to the controller under test.

[0046] Wherein, the second configuration word can adjust the parameters of the first function of the controller under test and there is a first preset fault when adjusting the first function of the controller under test.

[0047] In some embodiments, the first preset fault includes the faults that can occur when adjusting the first function. For example, when the first function is seat heating, adjusting the first function to medium temperature, but the actual temperature is high temperature, thus generating an adjustment fault.

[0048] In some embodiments, the first preset response data is the response data generated by the controller under test under normal circumstances based on the first configuration word. Since the first configuration word does not adjust the first function of the controller under test, the controller under test will not generate a fault code related to the first configuration word at present, and the generated first response data should be the response data at a historical moment.

[0049] In some embodiments, compare the first response data with the first preset response data. When the content of the first response data is also the fault code at the historical moment represented by the second response data, it indicates that the controller under test passes the test.

[0050] In some embodiments, the second control signal of the second configuration word is based on the first control signal of the first configuration word. Write the second configuration word in the first control signal, so that the second control signal for setting the second configuration word can adjust the second function of the controller under test, and adjust the second configuration word so that when controlling the first function through the second configuration word, a preset fault of the first function is generated, and then the second control signal for setting the second configuration word is sent to the controller under test.

[0051] Exemplarily, the first function is seat temperature, the binary representation of the first configuration word is 00000000, indicating that the seat temperature cannot be adjusted. Modify the first configuration word in the LIN signal for setting the first configuration word to the second configuration word. The binary representation of the second configuration word is 00100000, indicating that the seat temperature is adjusted to low temperature. At the same time, modify the second configuration word to simulate a fault of the seat temperature, so that when adjusting the seat temperature through the second configuration word, a fault of adjusting the seat temperature to high temperature will be generated. Thus, the second control signal of the second configuration word that will generate a fault of adjusting the seat temperature to high temperature when adjusting the seat temperature through the second configuration word is obtained, and this second control signal for setting the second configuration word is sent to the controller under test.

[0052] Step S104: Receive the second response data sent by the controller under test in response to the second control signal, and generate a first test result for the controller under test based on the second response data and the second preset response data.

[0053] In some embodiments, the second response data can be data such as status information, confirmation information, and fault codes that can reflect the result of writing the second configuration word and the current state of the controller under test.

[0054] In some embodiments, after receiving the second control signal for setting the second configuration word, the controller under test analyzes the first control signal, saves the obtained first configuration word, controls the first function of the controller under test based on the control instructions or parameters of the second configuration word. During the control process, the state of the controller under test controlling the first function is detected to generate second response data, and the second response data is sent. Among them, since a preset fault will occur when adjusting the first function of the controller under test through the second configuration word, the second response data generated under the normal condition of the controller under test can reflect the preset fault.

[0055] In some embodiments, the second preset response data is a fault code generated by the controller under test under normal conditions, which can reflect that the first function of the controller under test is adjusted through the second configuration word and a preset fault occurs.

[0056] In some embodiments, the second response data is compared with the second preset response data to generate a first test result indicating whether the controller under test meets the preset requirements. It can be understood that when both the generated second response data and the second preset response data represent that a preset fault occurs when adjusting the first function of the controller under test through the second configuration word, the first test result indicating that the controller under test meets the preset requirements can be understood that the controller under test can generate correct fault codes according to the control signals of different configuration words; when the generated second response data is different from the second preset response data, that is, when the second response data does not reflect that a preset fault occurs when adjusting the first function of the controller under test through the second configuration word, a first test result indicating that the controller under test does not meet the preset requirements is generated, which can be understood that the controller under test cannot generate correct fault codes according to the control signals of different configuration words.

[0057] In the embodiments of the present application, for the functions in the controller under test that need to be adjusted by writing configuration words, first, a first control signal with a first configuration word that cannot adjust the first function of the controller under test is sent to the controller under test. Based on the first response data generated after the controller under test executes the first configuration word and the first preset response data, the first test of the controller under test is performed, and it can be determined whether the controller under test meets the preset requirements without executing the configuration word, thereby improving the subsequent test accuracy. By sending a second control signal with a second configuration word that can adjust the controller under test and simulating a preset fault when adjusting the first function of the controller under test through the second configuration word, based on the second response data obtained by the controller under test through the second control signal with the second configuration word and the preset second response data, it is determined whether the controller under test can identify the existence of a preset fault, thereby further locating the problem of the controller under test to improve the test accuracy of the controller under test. In addition, through the solution of the present application, the controller under test is gradually tested, the problem cause of the controller under test can be quickly located, and while improving the accuracy of testing the controller under test, the test efficiency is also improved.

[0058] Figure 2 FIG. is a schematic flowchart of the implementation of a test method provided by an embodiment of the present application, and this method can be executed by a processor of a computer device. Based on Figure 1 , Figure 1 In step S104 in, it can be updated to step S201, and the steps shown in Figure 2 will be described.

[0059] Step S201: When the second response data and the second preset response data are different, generate a first test result indicating that the controller under test is unqualified.

[0060] In some embodiments, the second response data and the second preset response data are compared. When the second response data and the second preset response data are different, a first test result indicating that the controller under test is unqualified is generated. It can be understood that if the second preset response data reflects that a preset fault occurs when adjusting the first function of the controller under test through the second configuration word of the second control signal, and the second response data reflects that no preset fault occurs when adjusting the first function of the controller under test through the second configuration word of the second control signal, it indicates that the second preset response data and the second response data are different, thereby generating a first test result that the controller under test is unqualified.

[0061] Among them, the unqualified controller under test indicates that when adjusting the first function of the controller under test based on the configuration word, the controller under test cannot accurately identify the occurrence of a fault, thereby locating the problem that the controller under test cannot identify the fault.

[0062] Exemplarily, the first function is the seat temperature. The binary representation of the second configuration word is 00100000, indicating that the seat temperature is adjusted to a low temperature. At the same time, the second configuration word is modified to simulate a fault in the seat temperature, so that a fault of adjusting the seat temperature to a high temperature will occur when the seat temperature is adjusted through the second configuration word. The second preset response data reflects that a high-temperature fault occurs when the seat temperature is adjusted through the second configuration word, and the second response data reflects that no fault occurs when the seat temperature is adjusted to a low temperature through the second configuration word. It can be seen that the second response data is different from the second preset response data, thereby generating a first test result that the to-be-tested controller cannot recognize the occurrence of a fault when adjusting the first function through the configuration word.

[0063] In the embodiment of the present application, based on the second response data obtained by the to-be-tested controller through the second control signal for setting the second configuration word, it is determined whether the to-be-tested controller can recognize the existence of a preset fault by comparing the second response data with the preset second response data. In this way, the problem of the unqualified to-be-tested controller can be further located to improve the accuracy of testing the to-be-tested controller.

[0064] Figure 3 It is a schematic flowchart of the implementation process of a test method provided by an embodiment of the present application, and this method can be executed by the processor of a computer device. Based on Figure 1 , Figure 1 Step S104 in can be updated to step S301 to step S302, and will be described in combination with Figure 3 the steps shown.

[0065] Step S301: When the second response data is the same as the second preset response data, send a third control signal for setting a third configuration word to the to-be-tested controller.

[0066] Among them, the third configuration word can adjust the parameters of the first function of the to-be-tested controller.

[0067] In some embodiments, the second response data is compared with the second preset response data. When the second response data is the same as the second preset response data, a first test result indicating that the to-be-tested controller is qualified is generated. It can be understood that if the second preset response data reflects that a preset fault occurs when adjusting the first function of the to-be-tested controller through the second configuration word of the second control signal, and the second response data also reflects that a preset fault occurs when adjusting the first function of the to-be-tested controller through the second configuration word of the second control signal, it indicates that the second preset response data is the same as the second response data, thereby generating a first test result that the to-be-tested controller is qualified.

[0068] Among them, the qualification of the to-be-tested controller is characterized in that when adjusting the first function of the to-be-tested controller based on the configuration word, the to-be-tested controller can accurately identify the occurrence of a fault and can generate response data reflecting the occurrence of the fault, so as to locate the problem that the to-be-tested controller cannot identify the fault.

[0069] Exemplarily, the first function is the seat temperature, and the binary expression of the second configuration word is 00100000, which represents adjusting the seat temperature to a low temperature. At the same time, the second configuration word is modified to simulate a fault in the seat temperature, so that a fault of adjusting the seat temperature to a high temperature will occur when adjusting the seat temperature through the second configuration word; wherein the second preset response data reflects the occurrence of a high temperature fault when adjusting the seat temperature through the second configuration word, and the second response data reflects the occurrence of a high temperature fault when adjusting the seat temperature through the second configuration word. It can be seen that the second response data is the same as the second preset response data, thereby generating a first test result that the to-be-tested controller can accurately identify the occurrence of a fault when adjusting the first function through the configuration word.

[0070] In some embodiments, the third control signal for setting the third configuration word is obtained by eliminating the preset fault generated when adjusting the first function of the to-be-tested controller through the second configuration word on the basis of the second control signal for setting the second configuration word; it can be understood that the first function of the to-be-tested controller can be adjusted through the third configuration word, but no fault will occur. Thus, the third control signal for the third configuration word that can adjust the first function of the to-be-tested controller is sent to the to-be-tested controller.

[0071] Exemplarily, the first function is the seat temperature, and the binary expression of the second configuration word is 01000000, which represents adjusting the seat temperature to a low temperature. The second configuration word in the LIN signal for setting the first configuration word is modified to the third configuration word, and the binary expression of the third configuration word is 00010000, which represents adjusting the seat temperature to a medium temperature. At the same time, the high temperature fault generated when adjusting the first function of the to-be-tested controller through the second configuration word is eliminated, so that when adjusting the seat temperature through the third configuration word, the seat temperature can be adjusted to a medium temperature and no high temperature fault will occur. Thus, the third control signal for the third configuration word that no fault of adjusting the seat temperature to a high temperature will occur when adjusting the seat temperature to a medium temperature through the third configuration word is obtained, and the third control signal for the set three configuration words is sent to the to-be-tested controller.

[0072] Step S302, receive the third response data of the to-be-tested controller for the third control signal, and generate a first test result for the to-be-tested controller based on the third response data and the third preset response data.

[0073] In some embodiments, the third response data may be data such as status information, confirmation information, and fault codes that can reflect the result of writing the third configuration word and the current state of the to-be-tested controller.

[0074] In some embodiments, after receiving the third control signal with the third configuration word set, the controller under test first parses the third control signal to obtain the third configuration word and the control instruction or control parameter corresponding to the third configuration word and saves them; then, during the process of adjusting the first function of the controller under test with the control instruction or control parameter corresponding to the third configuration word, the controller under test continuously detects the adjustment state to generate the third response data when the third configuration word controls the first function, and sends the third response data.

[0075] In some embodiments, the third preset response data indicates that the first function of the controller under test can be adjusted by the third configuration word.

[0076] In some embodiments, the third preset response data and the third response data are compared, and based on the third preset response data and the third response data, it is determined whether the controller under test meets the preset requirements, so as to generate the first test result of whether the controller under test is qualified. It can be understood that if the third response data indicates that the first function of the controller under test cannot be adjusted by the third configuration word, it means that the third preset response data and the third response data are different, and it is determined that the controller under test does not meet the preset requirements, so as to generate the first test result that the controller under test is unqualified; if the third response data indicates that the first function of the controller under test can be adjusted by the third configuration word, it means that the third preset response data and the third response data are the same, and it is determined that the controller under test meets the preset requirements, so as to generate the first test result that the controller under test is qualified.

[0077] In the embodiments of the present application, first, through the second response data and the second preset response data, it can be determined that the controller under test can accurately identify the generated faults when adjusting the first function of the controller under test through the configuration word. Secondly, a third control signal that can adjust the control process of the controller under test without generating faults through the third configuration word is sent to the controller under test. Based on the third response signal and the third preset response signal generated by adjusting the first function of the controller under test through the third configuration word, it is determined whether the controller under test can accurately adjust the first function of the controller under test through the third configuration word. In this way, after excluding the influence of faults on the controller under test, it can be accurately identified whether the controller under test can accurately adjust the third function through the third configuration word, thereby improving the accuracy and efficiency of the test.

[0078] Figure 4 It is a schematic flowchart of the implementation process of a test method provided by the embodiments of the present application, and this method can be executed by the processor of a computer device. Based on Figure 3 , Figure 3 The step S302 in can be updated to step S401 or step S402, and will be described in combination with the steps shown in Figure 4 shown.

[0079] Step S401: When the third response data is the same as the third preset response data, generate a first test result indicating that the to-be-tested controller is qualified.

[0080] In some embodiments, the third preset response data represents adjusting the first function of the to-be-tested controller to a first state through a third configuration word.

[0081] In some embodiments, if the third response data represents that the first function of the to-be-tested controller can be adjusted to the first state through the third configuration word, it indicates that the third preset response data is the same as the third response data, determines that the to-be-tested controller meets the preset requirements, and thus generates a first test result indicating that the to-be-tested controller is qualified.

[0082] Wherein, the qualification of the to-be-tested controller represents that the to-be-tested controller can accurately identify that the first function of the to-be-tested controller can be adjusted to the first state through the third configuration word.

[0083] Exemplarily, the first function is the seat temperature, the first state is high temperature, the binary expression of the third configuration word is 00100000, which represents adjusting the seat temperature to high temperature. The third preset response data reflects that the seat temperature is adjusted to high temperature through the third configuration word, and the third response data also reflects that the seat temperature is adjusted to high temperature through the third configuration word. It can be seen that the third response data is the same as the third preset response data, and thus a first test result that the to-be-tested controller can accurately identify adjusting the first function through the configuration word is generated.

[0084] Step S402: When the third response data is different from the third preset response data, generate a first test result indicating that the to-be-tested controller is unqualified.

[0085] In some embodiments, if the third response data represents that the first function of the to-be-tested controller can be adjusted to a second state through the third configuration word, it indicates that the third preset response data is different from the third response data, determines that the to-be-tested controller does not meet the preset requirements, and thus generates a first test result indicating that the to-be-tested controller is unqualified.

[0086] Wherein, the unqualified of the to-be-tested controller represents that the to-be-tested controller cannot accurately identify that the first function of the to-be-tested controller can be adjusted to the first state through the third configuration word.

[0087] Exemplarily, the first function is seat temperature, the first state is high temperature, the second state is low temperature, and the binary expression of the third configuration word is 00100000, indicating that the seat temperature is adjusted to high temperature. The third preset response data reflects that the seat temperature is adjusted to high temperature through the third configuration word, and the third response data reflects that the seat temperature is adjusted to low temperature through the third configuration word. It can be seen that the third response data and the third preset response data are different, thereby generating a first test result that the controller to be tested cannot accurately identify the adjustment of the first function to the first state through the configuration word.

[0088] In an embodiment of the present application, by comparing whether the third response data and the third preset response data are the same, it is determined whether the control to be tested can correctly identify the adjustment of the first function to the first state through the third configuration word. In this way, it can be determined whether the controller to be tested is qualified, thereby improving the accuracy of the test.

[0089] In some embodiments, after the above step S103 receives the first response data for the first control signal sent by the controller under test, it also includes the following implementation process.

[0090] When the first response data is different from the first preset response data, a second test result indicating that the controller to be tested is unqualified is generated.

[0091] In some embodiments, the first preset response data is response data generated based on the first configuration word when the controller under test is normally tested. Since the first configuration word will not adjust the first function of the controller under test, the controller under test will not currently generate a fault code related to the first configuration word, and the first preset response data reflects the response data at a historical moment.

[0092] In some embodiments, if the first response data reflects that a fault occurs when adjusting the first function of the controller under test through the first configuration word, it is determined that the controller under test cannot accurately identify the first configuration word based on the inability to adjust the first function of the controller under test, then the first response data and the second response data are different, and a second test result is generated indicating that the controller under test is unqualified.

[0093] In an embodiment of the present application, a first test is performed on the controller to be tested based on first response data and first preset response data generated after the controller to be tested executes a first configuration word. When the first response data and the first preset response data are different, it can be determined that the controller to be tested does not meet the preset requirements when the configuration word is not executed. In this way, a test result indicating that the controller to be tested is unqualified can be generated, thereby improving the efficiency of testing the controller to be tested.

[0094] Figure 5Schematic diagram of the implementation process of a test method provided by an embodiment of this application. This method can be executed by a processor of a computer device. This method includes steps S501 to S503, which will be described in combination with Figure 5 the steps shown.

[0095] Step S501: Send a fourth control signal without a configured word to the controller under test.

[0096] Among them, the fourth control signal can adjust the second function of the controller under test and there is a second preset fault when adjusting the second function of the controller under test.

[0097] In some embodiments, the second function represents the basic function of the vehicle, such as simple lighting adjustment, wiper adjustment, emergency braking adjustment, etc.

[0098] In some embodiments, the second preset fault includes the faults that can occur when adjusting the second function. For example, when the second function is the high beam, adjusting the second function to turn on the high beam, but actually it turns on and then turns off after turning on the high beam.

[0099] In some embodiments, for the second function in the controller under test that does not need to be controlled by a configured word, first obtain a fourth control signal that can control the second function. This fourth control signal can simulate the second preset fault and send this fourth control signal to the controller under test. Among them, the fourth control signal can be a control signal such as a Local Interconnect Network (LIN) signal or a Controller Area Network (CAN) signal for controlling the basic functions of the vehicle.

[0100] Exemplarily, send a fourth control signal that controls the high beam to turn on but will generate a fault of turning on and then turning off to the electronic control unit.

[0101] Step S502: Receive the fourth response data of the controller under test for the fourth control signal.

[0102] In some embodiments, the fourth response data can be data such as status information, confirmation information, and fault codes that can reflect the current state of the second function of the controller under test.

[0103] In some embodiments, after receiving the fourth control signal, the controller under test parses the fourth control signal to obtain the control instruction in the fourth control signal. When controlling the second function of the controller under test through the control instruction in the fourth control signal, generate the fourth response data and send the fourth response signal.

[0104] Exemplarily, after sending a fourth control signal to the electronic control unit to turn on the high beam but with a fault that it turns off after being turned on, the electronic control unit parses the control instruction of the fourth control signal. When controlling the high beam through the control instruction in the fourth control signal, third response data will be generated.

[0105] To turn on the high beam, since the fourth control signal will cause the high beam to turn off after being turned on, thus generating

[0106] Step S503: Generate a third test result based on the fourth response data and the fourth preset response data.

[0107] In some embodiments, the fourth preset response signal indicates that when the controller under test is qualified, a second preset fault will occur when controlling the second function through the fourth control signal.

[0108] In some embodiments, compare the fourth preset response signal and the fourth response signal. If the fourth response signal indicates that a second preset fault will occur when controlling the second function through the fourth control signal, it means that the fourth preset response signal and the fourth response signal are the same, thus generating a third test result indicating that the controller under test can accurately identify the fault. If the fourth response signal indicates that a second preset fault will not occur when controlling the second function through the fourth control signal, it means that the fourth preset response signal and the fourth response signal are different, thus generating a third test result indicating that the controller under test cannot accurately identify the fault.

[0109] In the embodiments of the present application, for the functions of the controller under test that do not need to be adjusted by writing configuration words, first send a fourth control signal simulating the second preset fault to the controller under test to obtain fourth response data, and determine whether the controller under test can accurately identify the fault based on the fourth response data and the fourth preset response data, so as to determine whether the controller under test is qualified. In this way, the controller under test can be accurately tested, improving the test efficiency and accuracy.

[0110] Figure 6 It is a schematic implementation flowchart of a test method provided by the embodiments of the present application, and this method can be executed by the processor of a computer device. Based on Figure 5 , Figure 5 Step S503 in Figure 6 can also be updated to step S601, which will be described in combination with the steps shown in

[0111] Step S601: Generate a third test result indicating that the controller under test is unqualified when the fourth response data and the fourth preset response data are different.

[0112] In some embodiments, the fourth preset response signal indicates that when the controller under test is qualified, a second preset fault will occur when the second function is controlled by the fourth control signal.

[0113] In some embodiments, if the fourth response signal indicates that the second preset fault will not occur when the second function is controlled by the fourth control signal, it indicates that the fourth preset response signal is different from the fourth response signal, and it is determined that the controller under test cannot accurately identify the fault, thereby generating a third test result indicating that the controller under test is unqualified.

[0114] Exemplarily, the second function is the high beam. The fourth preset response signal indicates a fault that the high beam is turned on and then turned off, and the fourth response signal indicates that there is no fault that the high beam is turned on and then turned off. Thus, it can be determined that the controller under test cannot accurately identify the fault that the high beam is turned on and then turned off, and thereby generate a third test result indicating that the controller under test is unqualified.

[0115] In the embodiments of the present application, by comparing the fourth response data with the fourth preset response data, to determine whether the second preset fault in the fourth preset response data can be reflected by the fourth response data. If the fourth response data cannot reflect the second preset fault, it can be determined that the controller under test accurately identifies the fault, and thus it is determined that the controller under test is unqualified. In this way, it is possible to accurately locate whether the controller under test is qualified based on the response data of the controller under test, thereby improving the test efficiency.

[0116] Figure 7 FIG. is a schematic implementation flowchart of a test method provided by an embodiment of the present application, and this method can be executed by a processor of a computer device. Based on Figure 5 , Figure 5 Step S503 in can also be updated to steps S701 to S703 or step S704, and will be described in combination with the steps shown in Figure 7 Illustrated steps

[0117] Step S701: When the fourth response data is the same as the fourth preset response data, send a fifth control signal without a configured word to the controller under test.

[0118] Wherein, the fifth control signal can adjust the second function of the controller under test.

[0119] In some embodiments, the fourth preset response signal indicates that when the controller under test is qualified, a second preset fault will occur when the second function is controlled by the fourth control signal.

[0120] In some embodiments, if the fourth response signal indicates that the second preset fault will occur when the second function is controlled by the fourth control signal, it indicates that the fourth preset response signal is the same as the fourth response signal.

[0121] In some embodiments, the fifth control signal is obtained by removing the second preset fault that simulates the second function in the fourth control signal on the basis of the fourth control signal. The fifth control function can control the second function to the target state, and the obtained fifth control function is sent to the controller under test.

[0122] Exemplarily, the fifth control signal for turning on the high beam is sent to the controller under test.

[0123] Step S702: Receive the fifth response data sent by the controller under test in response to the fifth control signal.

[0124] In some embodiments, the fifth response data can be data such as status information, confirmation information, and fault codes that can reflect the current state of the second function of the controller under test.

[0125] In some embodiments, after receiving the fifth control signal, the controller under test parses the fifth control signal to obtain a control instruction for controlling the second function. When controlling the second function to the target state through the control instruction for controlling the second function in the fifth control signal, the fifth response data for the second function is generated and the fifth response data is sent.

[0126] Step S703: Generate a third test result indicating that the controller under test is qualified when the fifth response data is the same as the fifth preset response data.

[0127] In some embodiments, the fifth preset response data represents that when the controller under test is qualified, since no fault will occur due to the fifth control instruction, the fifth preset response data is the fault code at a historical moment.

[0128] In some embodiments, when comparing the fifth response data with the fifth preset response data, if the fifth response data is the response data at a historical moment, it indicates that the fifth response data is the same as the fifth preset response data, and it is determined that the controller under test can accurately recognize controlling the second function to the target state through the fifth control signal, thereby generating a third test result indicating that the controller under test is qualified.

[0129] Exemplarily, the second function is to turn on the high beam, the fifth preset response data represents the fault code at a historical moment, and the fifth response data also represents the fault code at a historical moment, then it indicates that the fifth response data is the same as the fifth preset response data, and it is determined that the controller under test can accurately recognize that the fifth control signal turns on the high beam, thereby generating a third test result indicating that the controller under test is qualified.

[0130] Step S704: Generate a third test result indicating that the controller under test is unqualified when the fifth response data is different from the fifth preset response data.

[0131] In some embodiments, the fifth response data is compared with the fifth preset response data. If the fifth response data is a fault code at the current moment, it indicates that the fifth response data is different from the fifth preset response data, and it is determined that the controller under test cannot accurately identify controlling the second function to the target state through the fifth control signal, thereby generating a third test result indicating that the controller under test is unqualified.

[0132] Exemplarily, the second function is to turn on the high beam. The fifth preset response data represents the fault code at the historical moment, and the fifth response data represents that there is a fault that the high beam is turned on and then turned off, which indicates that the fifth response data is different from the fifth preset response data, and it is determined that the controller under test cannot accurately identify controlling the high beam to turn on through the fifth control signal, thereby generating a third test result indicating that the controller under test is unqualified.

[0133] In the embodiments of the present application, for the second function that does not need to be adjusted by writing configuration words for the controller under test, first, it is determined that the controller under test can accurately identify faults by comparing the fourth response data with the fourth preset response data. Secondly, by comparing the fifth response data with the fifth preset response data, it is determined whether the controller under test can accurately identify the process of controlling the second function. In this way, the problem that the controller under test cannot accurately identify faults can be excluded first, and then the process of whether the controller under test can accurately identify the control of the second function can be tested, improving the test efficiency and accuracy at the same time.

[0134] The following describes an exemplary application of a test method provided by the embodiments of the present application in an actual scenario.

[0135] Local Interconnect Network (LIN) communication is a low-cost, single-line transmission, highly flexible, and stable transmission serial communication network, which is mainly used in application scenarios such as automotive doors and windows, seats, sensors, and steering wheels that have low requirements for real-time performance and transmission speed but are cost-sensitive.

[0136] In the existing body domain controller, there are many electronic and electrical components involved in LIN communication, frequent signal interactions, an increasing amount of test content, and frequent operations in the test process. The test difficulties of LIN-type faults are the most prominent, and there are disadvantages such as low manual test efficiency and blocking product delivery.

[0137] In view of the above problems, the present application provides an automated test method for vehicle LIN - type faults. The entire test process, from obtaining the fault test task to generating control instructions, performing fault operations, and reading operation results, is automated, reducing manual intervention and improving test efficiency and accuracy. By clearly defining the target diagnostic trouble code (DTC) test items and fault operation types, the test is carried out more pertinently, quickly locating potential problem points. At the same time, multiple target DTC test items are tested to expand the test coverage range, which helps to discover more potential faults. The operation results of the test piece performing fault operations can be read in real - time to timely understand the test status, so as to make a quick response when problems occur.

[0138] The test types mainly involved in the test method provided by the present application include two major types of faults: configuration - word type and non - configuration - word type. The signal interaction types involve CAN / CANFD signals, DOIP signals, LIN signals, etc. The main LIN - type DTC types include multiple types of faults such as node - loss type, sensor - loss type, switch - adhesion type, communication - error type, LIN - light open - circuit type, relay type, etc.

[0139] Figure 8 FIG. shows a schematic structural diagram of a test system provided by an embodiment of the present application. Among them, 801 is a test host computer, 802 is a test tool, and 803 is an electronic control unit (ECU) to be tested. Among them, the host computer 801 is used to send LIN - type fault automated test setting parameters to the test tool 802. The test tool 802 is used to generate at least one test item based on the LIN - type fault automated test setting parameters, determine the test request for the target test item and send it to the electronic controller 803. The electronic controller 803 sends response data to the test tool 802 based on the test request for the target test item. The test tool 802 is also used to generate a test result based on the response data.

[0140] Figure 9 FIG. shows a schematic implementation flow diagram of a test method provided by an embodiment of the present application. This process can be executed by the processor of a computer device. This process includes steps S901 to S904, which will be described in conjunction with Figure 9 the steps shown.

[0141] Step S901: Obtain LIN - type fault automated test setting parameters from the host computer.

[0142] In some embodiments, LIN - class fault automated test setup parameters are obtained from a host computer; wherein, the LIN - class fault automated test scenario represents a scenario for testing a vehicle controller group to be tested; the LIN - class fault automated test setup parameters represent parameters for testing the vehicle controller group to be tested in the LIN - class fault automated test scenario; the automated test setup parameters can be the baud rate, frame format, transmission node, etc. of LIN - class signals.

[0143] Step S902: Based on the automated test setup parameters, determine at least one test item.

[0144] In some embodiments, at least one test item is a test instance for testing the vehicle control functions of the vehicle controller group to be tested. At least one test item includes vehicle basic function test, vehicle optional function test, etc.

[0145] Step S903: Based on the test instruction obtained from the host computer, determine a target test item from at least one test item, and send a test request generated based on the target test item to the ECU to be tested.

[0146] In some embodiments, based on the test instruction for the vehicle optional function in the host computer, the vehicle optional function is determined as the target test item, and a LIN - class signal that needs to write a configuration word is generated based on the target vehicle optional function and sent to the ECU to be tested.

[0147] Step S904: Receive the response data for the target test item sent by the ECU to be tested, and generate a test result based on the response data and the preset response data.

[0148] In some embodiments, the ECU to be tested generates a corresponding fault code based on the received LIN - class signal that needs to write a configuration word.

[0149] In some embodiments, a test result is generated based on the received fault code and the preset fault code; wherein, when the received fault code is the same as the preset fault code, a test result indicating that the ECU to be tested is qualified is generated, and when the received fault code is different from the preset fault code, a test result indicating that the ECU to be tested is unqualified is generated.

[0150] In some embodiments, after obtaining the test result of the LIN - class fault, the LIN - class fault test result can be sent to the host computer to be presented to the user through the display interface of the host computer, so that the user can intuitively read the LIN - class fault automated test result.

[0151] Figure 10Schematic diagram of the implementation process of an overall testing method provided by an embodiment of this application. This method can be executed by a processor of a computer device. This method includes step S1001 and step S1002, which will be described in combination with Figure 10 the steps shown.

[0152] Step S1001: Check the preconditions of the test system.

[0153] In some embodiments, the test system includes an ECU under test, a test tool, and a host computer; it is detected that the ECU under test, the test tool, and the host computer are in a startup state, and the LIN communication is in an enabled state, the power supply voltage of each module is within the normal range, and the power supply has been in the on state for more than 3 seconds.

[0154] Step S1002: Determine whether the LIN type signal contains a configuration word.

[0155] In some embodiments, when the LIN type signal contains a configuration word, the test is performed based on the first test process; when the LIN type signal does not contain a configuration word, the test is performed based on the second test process.

[0156] Figure 11 Schematic diagram of the implementation process of a testing method that requires writing a configuration word provided by an embodiment of this application. This process can be executed by a processor of a computer device. This process includes steps S1101 to S1103, which will be described in combination with the steps shown in Figure N.

[0157] Step S1101: Read the first fault code of the LIN signal that has not been written with a configuration word and has not simulated a fault.

[0158] In some embodiments, it is necessary to set the first fault verification DTC code (DTC_HighBytes = 0xXX, DTC_MiddleBytes = 0xXX, DTC_LowBytes = 0xXX, DTC_Status = 0x08), where DTC_Status = 0x08 represents the historical fault state. Then clear the current associated configuration word content, restart the ECU to make the written configuration word content take effect, and then read whether the configuration word content is successfully written, read the current first fault code. If the first fault code is the same as the fault verification DTC code, it means that the current DTC will not be triggered in the state of not writing the configuration word, and the test passes and continues to execute step N02; otherwise, the test fails and the current test item ends.

[0159] Step S1102: Read the second fault code of the LIN signal that has been written with a configuration word and has simulated a fault.

[0160] In some embodiments, it is necessary to set the second fault verification DTC code (DTC_HighBytes = 0xXX, DTC_MiddleBytes = 0xXX, DTC_LowBytes = 0xXX, DTC_Status = 0x09), where DTC_Status = 0x09 indicates the current fault status. Then write the current associated configuration word content, restart the ECU to make the written content of the configuration word take effect, and then read whether the configuration word content is written successfully. At the same time, simulate the triggering of the current target DTC (simulate sending CAN / CANFD signals, DOIP signals, LIN signals), read the current second fault code. If the second set fault verification DTC code appears, it means that the current set fault verification DTC code will be triggered in the state of writing the configuration word, that is, the test passes and continue to execute step N03. Otherwise, the test fails and the current test item ends.

[0161] Step S1103: Read the third fault code of the LIN signal that writes the configuration word and clears the simulated fault.

[0162] In some embodiments, it is necessary to set the third fault verification DTC code (DTC_HighBytes = 0xXX, DTC_MiddleBytes = 0xXX, DTC_LowBytes = 0xXX, DTC_Status = 0x08), where DTC_Status = 0x08 indicates the historical fault status. Then write the current associated configuration word content, restart the ECU to make the written content of the configuration word take effect, and then read whether the configuration word content is written successfully. At the same time, eliminate the simulated triggered fault (simulate sending CAN / CANFD signals, DOIP signals, LIN signals), read the current third fault code. If the current third fault verification DTC code appears, it means that the third fault verification DTC code will be triggered in the state of writing the configuration word, that is, the test fails. Otherwise, the test passes and the current test item ends.

[0163] In the embodiments of the present application, the entire test process, from obtaining the fault test task to generating control instructions, performing fault operations, and reading operation results, is automated, reducing manual intervention and improving test efficiency and accuracy. By clarifying the target DTC test items and fault operation types, the test is more targeted, quickly locating potential problem points. At the same time, multiple target DTC test items are tested to expand the test coverage range, helping to discover more potential faults. It is possible to read the results of the fault operation executed by the test piece in real time, timely understand the test status, so as to quickly respond when problems occur.
