[0089] Example 1

[0090] Please see Figure 1 , Figure 1 A flow chart of a method for testing a message of an automobile motor controller provided in this embodiment. The method for testing a message of an automobile motor controller includes:

[0091] S101, obtaining test requirements for a vehicle motor controller message test and a set of preset signal modification values ​​corresponding to the test requirements.

[0092] S102: When the test requirement is to test the MCU receiving a message signal, obtain a first sending message to be sent.

[0093] In this embodiment, when the test requirement is to test the message signal received by the MCU, it means that the message signal to be tested is a signal in the message received by the MCU (motor controller).

[0094] S103: Determine a current target signal value to be modified according to a preset signal modification value set.

[0095] In this embodiment, the preset signal modification value set includes at least a preset maximum value, a preset minimum value, and at least one preset intermediate value.

[0096] In this embodiment, the target signal value is one of a preset maximum value, a preset minimum value, and a preset intermediate value.

[0097] S104: Modify the signal value of the first sent message to the target signal value to obtain a modified second sent message.

[0098] S105: Send a second sending message according to a preset message period.

[0099] S106. After the first preset time period, read a message to be tested corresponding to the second sent message in the program.

[0100] In this embodiment, the first preset time period may be 500 ms.

[0101] S107: Obtain variable values ​​of the message to be tested.

[0102] S108, judging whether the variable value of the message to be tested is consistent with the target signal value, if so, executing step S109; if not, executing step S110.

[0103] In this embodiment, the signal value of the second sent message is the target signal value.

[0104] S109: Determine that the first test result is that the test of the MCU receiving message signal against the target signal value is successful, and execute step S111.

[0105] S110. Determine that the first test result is that the test of the MCU receiving message signal against the target signal value fails, and execute step S112.

[0106] S111. Generate a test report according to the first test result, the variable values ​​of the message to be tested, and the target signal value.

[0107] In this embodiment, the method can first modify the value of the sent message signal to the maximum value, and start sending messages according to the message cycle. After waiting for T1 (i.e., the first preset time period), the variable value corresponding to the message signal to be tested in the program is read through XCP, and the program variable value and the sent signal value are compared to see if they are consistent. If they are consistent, the test of the maximum value of the MCU receiving the message signal passes, and the read program variable value and the sent message signal value are printed in the test report. Otherwise, the test of the maximum value of the MCU receiving the message signal fails.

[0108] In this embodiment, the method can modify the value of the sent message signal to the minimum value, and start sending messages according to the message cycle. After waiting for T1, the variable value corresponding to the message signal to be tested in the program is read through XCP, and the program variable value and the sent signal value are compared to see if they are consistent. If they are consistent, the MCU receives the message signal minimum value test and passes, and prints the read program variable value and the sent message signal value into the test report. Otherwise, the MCU receives the message signal maximum value test and fails.

[0109] In this embodiment, the method can continue to modify the value of the sent message signal to the intermediate value, and start sending messages according to the message cycle. After waiting for T1, the variable value corresponding to the message signal to be tested in the program is read through XCP, and the program variable value and the sent signal value are compared to see if they are consistent. If they are consistent, the MCU receives the message signal intermediate value test and passes, and prints the read program variable value and the sent message signal value into the test report. Otherwise, the MCU receives the message signal intermediate value test and fails, and stops sending messages.

[0110] S112: Delete the target signal value from the preset signal modification value set to obtain an updated preset signal modification value set.

[0111] S113, determining whether the updated preset signal modification value set is empty, if so, executing step S114; if not, executing step S103.

[0112] In this embodiment, when the updated preset signal modification value set is empty, it is determined that the test on the MCU receiving the message signal is completed.

[0113] In this embodiment, the method can eliminate randomness by testing the maximum value, minimum value, and intermediate value (any value between the maximum value and the minimum value) of the message signal and performing multiple measurements on the same signal, thereby ensuring the correctness of the signal range.

[0114] S114. Summarize all test reports to obtain a signal test summary report, and output the signal test summary report.

[0115] Please see Figure 2 , Figure 2 An example flow chart of a method for testing a message of an automobile motor controller is shown.

[0116] In this embodiment, the execution subject of the method may be a computing device such as a computer or a server, and no limitation is made in this embodiment.

[0117] In this embodiment, the execution subject of the method may also be a smart device such as a smart phone, a tablet computer, etc., which is not limited in this embodiment.

[0118] In this embodiment, a communication message automation test script for implementing the above method can be written based on the canoe software using the CAPL language, that is, the communication message automation test script can be the execution subject of this method.

[0119] It can be seen that the automobile motor controller message testing method described in this embodiment can automatically test the correctness of communication messages without human intervention, thereby solving the problems of low test efficiency and high risk of errors caused by manual operation and improving test efficiency.

[0125] S203: Determine the target variable value to be modified according to the preset signal modification value set.

[0126] S204: Modify the variable value of the first message signal to the target variable value to obtain a second message signal.

[0127] S205. After the second preset time period, read the received message sent by the MCU.

[0128] In this embodiment, the first preset time period and the second preset time period may be the same or different, and this embodiment does not impose any limitation on this.

[0129] In this embodiment, the second preset time period may be 500 ms.

[0135] S210: Generate a test report according to the second test result, the signal value of the message sent by the MCU, and the target variable value.

[0136] In this embodiment, the method can first modify the variable value corresponding to the message signal in the program to the maximum value through XCP, wait for T2 (i.e., the second preset time period, T2 can be equal to T1), read the received MCU sent message signal value, and compare whether the program variable value and the received signal value are consistent. If they are consistent, the MCU sends the message signal maximum value test passes, and the read program variable value and the sent message signal value are printed in the test report, otherwise the MCU sends the message signal maximum value test fails.

[0137] In this embodiment, the method can modify the variable value corresponding to the message signal in the program to the minimum value through XCP, wait for T2, read the received MCU send message signal value, compare the program variable value and the received signal value to see if they are consistent, if they are consistent, the MCU sends the message signal minimum value test passed, and the read program variable value and the sent message signal value are printed in the test report, otherwise the MCU sends the message signal minimum value test failed.

[0138] In this embodiment, the method can continue to modify the variable value corresponding to the message signal in the program to an intermediate value through XCP, wait for T2, read the received MCU sent message signal value, compare the program variable value and the received signal value to see if they are consistent, if they are consistent, the MCU sends the message signal intermediate value test passed, and the read program variable value and the sent message signal value are printed in the test report, otherwise the MCU sends the message signal intermediate value test failed, and stops sending messages.

[0140] Deleting the target variable value from the preset signal modification value set to obtain an updated preset signal modification value set;

[0141] Determine whether the updated preset signal modification value set is empty;

[0142] If not, the above-mentioned step of determining the current target variable value to be modified according to the preset signal modification value set is executed;

[0143] If yes, it is determined that the test of the message signal sent by the MCU is completed, and the following summary of all test reports is performed to obtain a signal test summary report.

[0144] In this embodiment, the method can eliminate randomness by testing the maximum value, minimum value, and intermediate value (any value between the maximum value and the minimum value) of the message signal and performing multiple measurements on the same signal, thereby ensuring the correctness of the signal range.

[0145] S211. Summarize all test reports to obtain a signal test summary report, and output the signal test summary report.

[0146] Please see Figure 4 , Figure 4 An example flow chart of a method for testing a message of an automobile motor controller is shown.
