The vehicle electromagnetic compatibility testing method locates the controller of the corresponding message signal in the signal transmission link according to the abnormal message signal, that is, quickly locates the abnormal controller, which is helpful to assist the user to quickly find out the specific cause of the abnormal working condition of the vehicle to be tested 100, and is helpful to improve the efficiency of abnormality detection, so as to facilitate rectification of the vehicle to be tested 100.

[0066] Reference Figure 1 and Figure 5 As shown, the following description takes the electronic module to be tested as a turn signal module as an example. The vehicle electromagnetic compatibility test method controls the turn signal of the vehicle to be tested 100 to keep operating, and controls the electromagnetic field transmitting antenna 300 to transmit an interfering electromagnetic field to the vehicle to be tested 100 to monitor whether the turn signal has an abnormal working condition.

[0067] Reference Figure 1 and Figure 5 As shown in the figure, the working principle of the turn signal is: triggered by the button switch, the trigger signal is transmitted to the upper controller, the upper controller preliminarily processes the trigger signal, and then transmits the signal to the body controller (Body Control Module, BCM) or domain controller, the BCM controller or domain controller then analyzes the trigger signal and sends the corresponding control command to the lamp controller, after receiving the control command, the lamp controller controls the lighting of the lamp.

[0068] Reference Figure 1 and Figure 5 As shown, in the corresponding step S330, the vehicle electromagnetic compatibility test method analyzes the message information to determine the signal transmission link of the turn signal module. The information transmission link of the turn signal module is: key switch-upper controller-BCM controller or domain controller-lamp controller-turn signal. That is, the message information includes the message signals of the upper controller, BCM controller or domain controller, and lamp controller; Reference Figure 1 and Figure 5As shown, in the corresponding step S340, the vehicle electromagnetic compatibility test method determines whether the message signal of each controller is abnormal step by step along the signal transmission link. That is, under the influence of the interference electromagnetic field, the vehicle electromagnetic compatibility test method checks whether the message signal sent by the upper controller is abnormal. If the message signal sent by the upper controller is normal, the message signal sent by the BCM controller or the domain controller is monitored downward to see if it is abnormal. If the message signal sent by the BCM controller or the domain controller is normal, the message of the lamp controller is monitored downward to see if it is abnormal.

[0069] Reference Figure 1 and Figure 5 As shown, in the corresponding step S410 of the vehicle electromagnetic compatibility test method, when any message signal is abnormal, for example, the message signal sent by the lamp controller is abnormal, the message information is determined to be abnormal, that is, an abnormality occurs at a certain node in the signal transmission link, resulting in an abnormal function of the electronic module to be tested.

[0070] Reference Figure 1 and Figure 5 As shown, in step S420, the vehicle electromagnetic compatibility testing method locates the lamp controller corresponding to the abnormal message signal, that is, it is determined that the lamp controller is subjected to interference from the electromagnetic field and produces an abnormal operating condition, resulting in the turn signal failing to operate normally. This is helpful in assisting the user to quickly find out the specific cause of the abnormal operating condition of the vehicle 100 to be tested, and is helpful in improving the efficiency of abnormality detection so as to facilitate rectification of the vehicle 100 to be tested.

[0071] Reference Figure 1 and Figure 5 As shown, it is difficult to find the specific reasons for abnormalities in the electronic modules such as the turn signal lamp through video monitoring in the traditional vehicle electromagnetic interference test. The vehicle electromagnetic compatibility test method can accurately monitor the abnormal working conditions of the vehicle by acquiring, analyzing and judging the message information, which is conducive to avoiding the problem of missing some key abnormal information of the vehicle working conditions and reducing the interference caused by human factors. When the vehicle electromagnetic compatibility test method determines that the message information is abnormal, the abnormal parts can be checked more quickly according to the abnormal points of the message information, which is conducive to assisting users to quickly find out the specific reasons for the abnormal working conditions of the vehicle 100 to be tested.

[0072] Reference Figure 1 and Figure 6 As shown, it can be understood that the vehicle electromagnetic compatibility test method controls the operation of the electronic module of the vehicle 100 to be tested, and controls the electromagnetic field transmitting antenna 300 to emit an interfering electromagnetic field to the vehicle 100 to be tested, in step S200, including the following steps: Step S210, setting interference parameters for testing the electronic module to be tested; Step S220, after the electromagnetic field transmitting antenna 300 emits the interfering electromagnetic field, the electromagnetic field transmitting antenna 300 is controlled to adjust the interference parameters of the interfering electromagnetic field according to a preset period.

[0073] Reference Figure 1 and Figure 6 As shown, in order to test the compatibility of the electronic module under test of the vehicle under test 100 with electromagnetic fields of various waveforms, frequency bands and intensities, the vehicle electromagnetic compatibility testing method pre-sets interference parameters of the electromagnetic field of the electronic module under test, and after controlling the electromagnetic field transmitting antenna 300 to emit an interfering electromagnetic field to the vehicle under test 100, the electromagnetic field transmitting antenna 300 can be controlled to adjust the interference parameters of the interfering electromagnetic field according to a preset period, and by changing the interference parameters such as the waveform, frequency band and intensity of the interfering electromagnetic field, in conjunction with the synchronous monitoring of the message information, the compatibility of the electronic module under test with electromagnetic fields of various waveforms, frequency bands and intensities can be judged, so as to improve the comprehensiveness of the test of the vehicle under test 100.

[0074] Reference Figure 1 and Figure 6 As shown, specifically, the interference parameters include waveform, frequency band and intensity, etc., so as to test the compatibility of the electronic module under test of the vehicle 100 under test with electromagnetic fields of various waveforms, frequency bands and intensities.

[0075] It should be noted that the preset period may be a time period, such as 1 minute, 2 minutes, 5 minutes, etc.

[0076] Reference Figure 1 and Figure 7 As shown, it can be understood that the vehicle electromagnetic compatibility testing method further includes the following steps: Step S500, when the message information is abnormal, analyzing the time node when the message information is abnormal, and extracting the interference parameters of the interfering electromagnetic field according to the time node; Step S600: Record abnormal message information and interference parameters.

[0077] Reference Figure 1 and Figure 7 As shown, specifically, when the vehicle electromagnetic compatibility test method determines that the message information is abnormal, it can analyze the time node of the message information abnormality and extract the interference parameters of the interference electromagnetic field at the time node, that is, it assists the user to determine under which interference parameters of the interference electromagnetic field the electronic module under test produces the abnormality. The vehicle electromagnetic compatibility test method can record the abnormal message information and interference parameters, so as to record the reasons for the abnormal vehicle operating conditions in more detail, which is convenient for designers to rectify the abnormal reasons of the vehicle 100 under test.

[0078] Reference Figure 1 and Figure 7As shown, after the vehicle electromagnetic compatibility testing method associates the abnormal message information with the interference parameters, it can be transmitted to the user in the form of a report, so that the user can intuitively find out which interference parameter's interference electromagnetic field causes the abnormal working condition of the vehicle 100 to be tested.

[0079] Reference Figure 1 and Figure 8 As shown, it can be understood that the vehicle electromagnetic compatibility testing method further includes the following steps: Step S700, building a video monitoring component and an audio monitoring component in the anechoic chamber 200; Step S800, controlling the video monitoring component to monitor the operating state of the vehicle 100 under the interference electromagnetic field, and controlling the audio monitoring component to monitor the operating state of the vehicle 100 under the interference electromagnetic field.

[0080] Reference Figure 1 and Figure 8 As shown, specifically, the vehicle electromagnetic compatibility testing method also builds a video monitoring component and an audio monitoring component in the anechoic chamber 200, controls the video monitoring component to monitor the operating status of the vehicle 100 under the interference electromagnetic field, and controls the audio monitoring component to monitor the operating status of the vehicle 100 under the interference electromagnetic field, that is, the vehicle electromagnetic compatibility testing method also adds video monitoring and audio monitoring of the vehicle 100 to be tested. By increasing the monitoring dimension of the vehicle 100 to be tested, it is beneficial to accurately record the abnormal operating condition information of the vehicle, reduce the risk of misjudgment, and analyze the abnormal message information to facilitate the detection of abnormal parts.

[0081] It should be noted that the structures and principles of the video monitoring components and the audio monitoring components belong to conventional technical means in this field and will not be described in detail here.

The setting of the anechoic chamber 200 is conducive to blocking external electromagnetic interference and improving the accuracy of the test. During the test, the electronic module to be tested of the vehicle 100 to be tested is controlled to operate, and the electromagnetic field transmitting antenna 300 is controlled to emit an interfering electromagnetic field to the vehicle 100 to be tested, and then the message information of the electronic module to be tested operating under the interfering electromagnetic field is obtained, and the message information is processed. The message information is analyzed to determine whether the message information is abnormal. Compared with the traditional video monitoring method, the vehicle electromagnetic compatibility test method achieves accurate monitoring of abnormal vehicle conditions by acquiring, analyzing and judging the message information, which is helpful to avoid missing some key abnormal information of the vehicle condition and reduce the interference caused by human factors. When the vehicle electromagnetic compatibility test method determines that the message information is abnormal, the abnormal parts can be checked more quickly according to the abnormal points of the message information, which is helpful to assist users to quickly find out the specific reasons for the abnormal condition of the vehicle 100 to be tested.
