[0029] As the use of automobiles becomes increasingly diversified and vehicle communication technology continues to mature, vehicle-mounted satellite communication technology has become an important development trend, providing consumers with services such as remote communication, fault monitoring, and vehicle remote diagnosis. The electromagnetic compatibility performance of vehicle communication equipment has an important impact on product reliability.

[0030] In the related art, the electromagnetic compatibility test of the vehicle's communication equipment only performs the electromagnetic compatibility test on the individual communication equipment, ignoring the influence of the entire vehicle body on the electromagnetic signal, resulting in inaccurate electromagnetic compatibility test results.

[0040] In a possible implementation manner, the simulation unit includes a simulation device and a first antenna.

[0041] The simulation device is connected to the first antenna, and the first antenna is connected to the vehicle for communication.

[0042] In this embodiment, the simulation device may be a comprehensive tester, and the model of the comprehensive tester may be SP8315, so as to realize the simulation of satellite communication. The comprehensive tester may be arranged outside the darkroom, and the first antenna may be arranged inside the darkroom, and the first antenna and the simulation device may be connected via a coaxial line.

[0045] Figure 2 is a flow chart of a vehicle electromagnetic compatibility testing method according to an exemplary embodiment. Figure 2 As shown, the method can be applied to a vehicle electromagnetic compatibility test device, comprising the following steps: In step S201, a first test parameter and a second test parameter of the vehicle are obtained, wherein the first test parameter is a parameter obtained by performing an electromagnetic radiation emission test on the vehicle when the vehicle is in a communication state, and the second test parameter is a parameter obtained by performing an electromagnetic immunity test on the vehicle when the vehicle is in a communication standby state and a communication state, respectively.

[0046] In this embodiment, an electromagnetic radiation emission test is performed on the vehicle when the vehicle is in a communication state, and a first test parameter characterizing the interference size of the vehicle in the communication state can be determined. When the vehicle is in a communication standby state and a communication state, an electromagnetic immunity test is performed on the vehicle respectively, and a second test parameter characterizing the anti-interference capability of the vehicle's communication equipment can be obtained.

[0047] In step S202, an electromagnetic compatibility test result is obtained according to the first test parameter and the second test parameter.

[0048] In this embodiment, through the first test parameter, it can be determined whether the interference caused by the vehicle to the surrounding electronic equipment during the communication process is qualified in the whole vehicle condition. Through the second test parameter, it can be determined whether the anti-interference ability of the vehicle's communication equipment is qualified in the whole vehicle condition, so as to obtain more accurate electromagnetic compatibility test results of the vehicle's communication equipment. In this way, the electromagnetic compatibility of the communication equipment can be verified at the whole vehicle level during the product development stage of the communication equipment to ensure the reliability of the communication equipment. In addition, the vehicle body is a metal structure, which has a certain reflection and refraction effect on electromagnetic waves. Compared with the component level test, the whole vehicle level test is closer to the actual vehicle usage scenario, so that the obtained test results are more accurate.

[0049] In a possible implementation manner, a method for obtaining an electromagnetic compatibility test result according to the first test parameter and the second test parameter may be: According to the first test parameter, a first test result is obtained; according to the second test parameter and the normal state parameter, a second test result is obtained; according to the first test result and the second test result, an electromagnetic compatibility test result is obtained.

[0050] In this embodiment, for the electromagnetic radiation emission test, a narrowband test can be performed based on GB34660, and the frequency range of the test can be 30MHz-1GHz, and the first test parameter is obtained through the electromagnetic interference test device and the second antenna. And based on the test requirements of GB34660, the first target condition is obtained, and then the first test result is determined by judging whether the first test parameter meets the first target condition. For the electromagnetic immunity test, based on ISO11451-2, the frequency range of the test can be 100kHz-6GHz, and the vehicle is subjected to electromagnetic interference through the electromagnetic interference test device and the second antenna, and the second test parameter is obtained through the electromagnetic interference test device and the second antenna, the simulation device and the first antenna, and the monitoring device, the first conversion device and the second conversion device. Then, based on the second test parameter and the normal state parameter, the second test result is obtained. Among them, the normal state parameter is the state parameter when the vehicle is in a normal communication state. Then, combined with the first test result and the second test result, a more accurate and comprehensive electromagnetic compatibility test result is obtained.

[0051] In a possible implementation, the first test parameter includes first transmit powers corresponding to multiple frequency points within a first target frequency range.

[0052] According to the first test parameter, the method for obtaining the first test result may be: When the first transmit power corresponding to the multiple frequency points meets the first target condition, the first test result is determined to be qualified; when the first transmit power corresponding to the multiple frequency points does not meet the first target condition, the first test result is determined to be unqualified.

[0053] In this embodiment, the electromagnetic interference testing equipment can receive the electromagnetic emission of the vehicle during the communication process when performing the electromagnetic radiation emission test to obtain the frequency point and the emission power. The first target frequency range can be 30MHz-1GHz. The first target condition can be that the emission power of any frequency point is less than the first power threshold. In the case where the first emission powers corresponding to multiple frequency points are all less than the first power threshold, it is determined that the first emission powers corresponding to the multiple frequency points meet the first target condition, and then the first test result can be determined to be qualified. In the case where any of the first emission powers corresponding to multiple frequency points is greater than or equal to the first power threshold, it is determined that the first emission powers corresponding to the multiple frequency points do not meet the first target condition, which may cause electromagnetic interference to other electronic equipment of the vehicle, and then the first test result can be determined to be unqualified.

[0054] In a possible implementation manner, before obtaining the second test result according to the second test parameter and the normal state parameter, the method further includes: Determine the original state of the vehicle according to the original state parameters of the vehicle; In the case where the original state is an abnormal communication state, the vehicle is adjusted until the vehicle is in a normal communication state; and the state parameters of the vehicle in the normal communication state are determined as normal state parameters.

[0055] In this embodiment, the normal state parameters of the vehicle may be determined first, and the original state parameters of the vehicle may be obtained. The original state parameters may be the original online state, the original error vector amplitude, and the original transmission power of the communication device of the vehicle. If the original online state is the communication state, and the original error vector is within the target error vector range, and the original transmission power is within the target transmission power range, then the original state of the vehicle is determined to be a normal communication state. If any of the following exists: the original online state is the communication standby state, the original error vector is not within the target error vector range, and the original transmission power is not within the target transmission power range, then the original state of the vehicle is determined to be an abnormal communication state.

[0056] When the original state is an abnormal communication state, the vehicle is adjusted until the vehicle is in a normal communication state, and the state parameters of the vehicle in the normal communication state, such as the second error vector amplitude and the third transmission power, are obtained. When the vehicle is in the normal communication state, the electromagnetic immunity test is performed again.

[0057] In a possible implementation, the second test parameters include a first online state, a second online state, a first error vector amplitude, and a second transmission power of the vehicle; the first online state is a parameter obtained by performing an electromagnetic immunity test on the vehicle when the vehicle is in a communication standby state; the second online state, the first error vector amplitude, and the second transmission power are parameters obtained by performing an electromagnetic immunity test on the vehicle when the vehicle is in a communication state; and the normal state parameters include the second error vector amplitude and the third transmission power corresponding to the vehicle in a normal communication state.

[0058] According to the second test parameter and the normal state parameter, the method for obtaining the second test result may be: When the first online state, the second online state, the first error vector magnitude, the second transmission power, the second error vector magnitude and the third transmission power meet the second target condition, the second test result is determined to be qualified; when the first online state, the second online state, the first error vector magnitude, the second transmission power, the second error vector magnitude and the third transmission power do not meet the second target condition, the second test result is determined to be unqualified.

[0059] In this embodiment, when the first online state is a communication pending state, and the second online state is a communication state, and the deviation between the first error vector amplitude and the second error vector amplitude is less than the first target threshold, and the deviation between the second transmit power and the third transmit power is less than the second target threshold, it is determined that the first online state, the second online state, the first error vector amplitude, the second transmit power, the second error vector amplitude and the third transmit power meet the second target condition, thereby determining that the second test result is qualified.

[0060] The deviation between the first error vector magnitude and the second error vector magnitude is calculated as follows: the first error vector magnitude is subtracted from the second error vector magnitude to obtain a first difference, and the ratio of the first difference to the first error vector magnitude is determined as the deviation between the first error vector magnitude and the second error vector magnitude. The deviation between the second transmit power and the third transmit power is calculated as follows: the second transmit power is subtracted from the third transmit power to obtain a second difference, and the ratio of the second difference to the second transmit power is determined as the deviation between the second transmit power and the third transmit power. Both the first target threshold and the second target threshold can be 10%.

[0061] If any of the following exists: the first online state is a communication state, the second online state is a communication pending state, the deviation between the first error vector amplitude and the second error vector amplitude is greater than or equal to the first target threshold, and the deviation between the second transmit power and the third transmit power is greater than or equal to the second target threshold, then it is determined that the first online state, the second online state, the first error vector amplitude, the second transmit power, the second error vector amplitude and the third transmit power do not meet the second target condition, and thus the second test result is determined to be unqualified.

[0062] Figure 3 is a flow chart of an electromagnetic immunity testing method according to an exemplary embodiment. Figure 3 As shown, the following steps are included: In step S301, it is determined that the original online state is a communication state.

[0063] In step S302, it is determined that the original error vector is within a target error vector range, and the original transmit power is within a target transmit power range.

[0064] In step S303, it is determined whether step S301 and step S302 are satisfied at the same time. If they are not satisfied at the same time, step S304 is executed. If they are satisfied at the same time, step S305 is executed.

[0065] In step S304, the vehicle is adjusted to a normal communication state, and step S305 is executed.

[0066] In step S305, an electromagnetic interference immunity test is performed in a communication state.

[0067] In step S306, it is determined that the second online state is a communication state.

[0068] In step S307, a deviation between the first error vector magnitude and the second error vector magnitude is smaller than a first target threshold, and a deviation between the second transmit power and the third transmit power is smaller than a second target threshold.

[0069] In step S308, it is determined whether step S306 and step S307 are satisfied at the same time. If both are satisfied at the same time, step S309 is executed. If both are not satisfied at the same time, step S310 is executed.

[0070] In step S309, it is confirmed that the electromagnetic immunity test in the communication state is qualified.

[0071] In step S310, it is confirmed that the electromagnetic immunity test in the communication state fails.

[0072] In a possible implementation manner, a method for obtaining an electromagnetic compatibility test result according to the first test result and the second test result may be: When both the first test result and the second test result are qualified, the electromagnetic compatibility test result is determined to be qualified; when one of the first test result and the second test result is unqualified, the electromagnetic compatibility test result is determined to be unqualified.

[0073] In this embodiment, the electromagnetic compatibility test result is determined to be qualified only when the first test result and the second test result are both qualified. When the first test result is unqualified or the second test result is unqualified, the electromagnetic compatibility test result is determined to be unqualified, so as to obtain a more accurate and comprehensive electromagnetic compatibility test result.
