[0039] Specifically, when starting the test, the preset fault injection function sequentially injects the to-be-tested fault into the LIN communication test channel.

[0059] The communication frame can be a LIN frame of normal communication in the LIN communication test channel.

[0060] The first preset flag is used for indicating that the to-be-tested fault injection is ended.

[0061] Specifically, the LIN communication test channel is detected by the first preset channel detection function at a certain time interval, and it is judged whether the first preset channel detection function detects a communication frame of normal communication of the LIN communication test channel. If the first preset channel detection function detects that the LIN communication test channel exists the communication frame, it indicates that the communication of the LIN communication test channel is normal at this time, the to-be-tested fault injection is ended, and the first check result bit is adjusted to the first preset flag bit.

[0062] Optionally, in another optional embodiment of the present application, after the LIN communication test channel is detected by the first preset channel detection function, the following steps are further included:

[0064] The second preset flag bit is preset as a flag bit displayed when the first preset channel detection function detects that the communication of the LIN communication test channel is abnormal; the second preset flag is used for indicating that the to-be-tested fault injection is not ended. For example, the second preset flag bit can be "0"; when the variable msg_return is equal to "0", it is determined that the communication of the LIN communication test channel is abnormal.

[0065] Specifically, the LIN communication test channel is detected by the first preset channel detection function at a certain time interval, and it is judged whether the first preset channel detection function detects a communication frame of normal communication of the LIN communication test channel. If the first preset channel detection function detects that the LIN communication test channel does not exist the communication frame, it indicates that the communication of the LIN communication test channel is abnormal at this time, the to-be-tested fault injection is not ended, and the first check result bit is adjusted to the second preset flag bit.

[0066] S240, detecting the LIN communication test channel by a second preset channel detection function.

[0067] The second preset channel detection function can be a function preset for detecting an error frame of the LIN communication test channel. For example, the second preset channel detection function can be a linReceiveError function

[0068] Specifically, the LIN communication test channel is detected by the second preset channel detection function at a certain time interval to determine whether there is an error frame in the LIN communication test channel.

[0069] S250, if the second preset channel detection function detects that there is an error frame in the LIN communication test channel, the second check result bit of the second preset channel detection function is adjusted to a third preset flag bit.

For example, the third preset flag bit can be set to "1".

[0072] Specifically, whether there is an error frame in the LIN communication test channel is determined by the second preset channel detection function. If the second preset channel detection function detects that there is an error frame in the LIN communication test channel, the second check result bit of the second preset channel detection function is adjusted to a third preset flag bit.

[0073] S260, if the second check result bit of the second preset channel detection function is the third preset flag bit, it is determined that the LIN communication test channel passes the communication test.

[0074] Specifically, if the second check result bit of the second preset channel detection function is the third preset flag bit, it means that there is an error frame in the LIN communication test channel after the fault injection ends, the communication of the LIN communication test channel is normal, and it is determined that the LIN communication test channel passes the communication test.

[0075] Optionally, in another optional embodiment of the present application, after the first check result bit of the first preset channel detection function is the first preset flag bit, it further includes:

[0076] If the second preset channel detection function detects that there is no error frame in the LIN communication test channel, the second check result bit of the second preset channel detection function is adjusted to a fourth preset flag bit; the fourth preset flag bit is used to indicate that the communication of the LIN communication test channel is not normal.

[0078] The fourth preset flag bit can be a flag bit preset in the second preset channel detection function when the LIN communication test channel does not send out an error frame. The fourth preset flag bit is used to indicate that the LIN communication test channel is not normal. For example, the third preset flag bit can be set to "0".

[0079] Specifically, whether an error frame is sent out in the LIN communication test channel is determined by the preset second preset channel detection function. If the second preset channel detection function detects that there is no error frame in the LIN communication test channel, the second check result bit of the second preset channel detection function is adjusted to the fourth preset flag bit. If the second check result bit of the second preset channel detection function is the fourth preset flag bit, it indicates that no error frame is sent out in the LIN communication test channel after the end of fault injection, the LIN communication test channel is not normal, the test of the LIN communication test channel is determined to fail, and the communication test is not passed.

In the case of normal communication, it is indicated that the fault injection is completed, and manual detection of the LIN communication channel is not needed, thereby improving the test efficiency. The LIN communication test channel is detected by the second preset channel detection function. If the second preset channel detection function detects that there is an error frame in the LIN communication test channel, the second check result bit of the second preset channel detection function is adjusted to the third preset flag bit. If the second check result bit of the second preset channel detection function is the third preset flag bit, it is determined that the LIN communication test channel passes the communication test. In the case that the first detection result is the first preset flag bit, it is determined that the LIN communication test channel is normal. The error frame of the LIN communication test channel is detected by setting the second preset channel detection function. When it is detected that the LIN communication test channel sends out an error frame, the second check result bit is changed to the third preset flag bit, the LIN communication test channel is automatically determined to be normal, the test result of the LIN bus is determined, the technical problems of low automation and low efficiency of vehicle logic channel communication test in the prior art are solved, the vehicle logic channel communication is quickly tested, the efficiency of vehicle logic channel communication test is improved, and the feasibility and accuracy of vehicle logic channel communication test are completed.
