Based on the gain information of the antenna under test, a first simulation model of the antenna under test and a second simulation model based on the vehicle under test can be determined. Driving data of the vehicle under test under different driving environments can then be determined. Finally, based on the determined first simulation model and the aforementioned driving data, the performance of the vehicle's antenna under test is tested, yielding the performance test results. This achieves the goal of testing the performance of the entire vehicle-level antenna under test, thus solving the technical problem of low accuracy in vehicle antenna performance testing and ultimately improving the accuracy of vehicle antenna performance testing.

[0079] In this embodiment, the vehicle's antenna model can be adjusted by executing the vehicle antenna model adjustment method. For example, Figure 2(a) is a flowchart of a vehicle antenna model adjustment method according to an embodiment of the present invention. As shown in Figure 2(a), the method may include the following steps:

[0080] Step S201: Measure the dynamic field strength at the vehicle antenna.

[0081] In the technical solution provided by step S201 of the present invention, in order to restore the electromagnetic environment of the whole vehicle under dynamic conditions, a spectrum analyzer should first be used to measure the magnitude of the field strength at the antenna position in the dynamic scene of the whole vehicle within a specified time. If there is a significant change, the state of the whole vehicle and the road conditions at this time should be recorded.

[0082] After measuring the dynamic field strength at the vehicle antenna, proceed to step S202, where an excitation source is set up 0.1m away from the antenna in the simulation environment.

[0083] In the technical solution provided in step S202 of the present invention, in order to recreate the electromagnetic scene of the actual vehicle in the simulation software, an excitation source is first set up 0.1m in front of the antenna, and a probe is set up at the antenna position. First, the size of the excitation source is randomly set, and a whole-vehicle simulation is performed to check the field strength at the probe. If the field strength shown in the simulation is inconsistent with the test results, the size of the excitation source is adjusted, and the simulation is repeated until the simulated field strength at the probe is consistent with the actual measured field strength. The size of the excitation source and the overall vehicle state are adjusted multiple times in the simulation to recreate the electromagnetic environment of the vehicle at the antenna position under dynamic conditions.

[0084] In the simulation environment, after setting the excitation source 0.1m away from the antenna, proceed to step S203 and set the probe at the antenna location.

[0085] After setting the probe at the antenna location, proceed to step S204 to begin the vehicle-level antenna simulation.

[0086] After starting the whole vehicle-level antenna simulation, proceed to step S205 to compare the obtained simulated field strength with the measured field strength measured by the probe.

[0087] After comparing the field strength obtained from the simulation with the field strength measured by the probe, step S206 is performed to adjust the excitation magnitude until the simulated field strength is consistent with the measured field strength.

[0088] After adjusting the excitation magnitude to match the simulated field strength with the measured field strength, proceed to step S207 to adjust the vehicle model under multiple time periods.

[0089] After adjusting the vehicle model under multiple time periods, proceed to step S208 and repeat steps S201 to S207 to perform multiple verifications.

[0090] In this embodiment, the performance of the vehicle-level antenna under test can be tested by performing a vehicle-level performance simulation method. For example, Figure 2(b) is a flowchart of a vehicle-level performance simulation method according to an embodiment of the present invention. As shown in Figure 2(b), the method may include the following steps:

[0091] Step S211: Set up the vehicle simulation model and the antenna simulation model.

[0092] In the technical solution provided by step S211 of the present invention, data acquisition is performed first: antenna gain is measured using a near-field scanning system in a microwave anechoic chamber; secondly, data processing is performed: the measured data format is converted into a gain distribution file recognizable by the simulation software; simultaneously, the frequency range and step size of the measured data are ensured to be consistent with the simulation settings, and the data point density is adjusted by interpolation if necessary. Through these methods, the normalization of test data and simulation data can be guaranteed. In the simulation software, for the antenna, non-radiating components (e.g., brackets, housings) are removed, retaining only the radiator and feed structure. Simultaneously, the complex three-dimensional antenna structure is replaced with an equivalent surface, and finally, the gain data is imported to replace the original antenna excitation source as input.

[0093] In this embodiment, the radiation from the cab wiring harness should be measured. Generally, this should be done on a road section where the commercial vehicle is traveling, using a handheld spectrum analyzer at the antenna location, and the measurement data should be recorded. This method allows for accurate recording of the electromagnetic environment of the commercial vehicle under different conditions. If it is necessary to record the electromagnetic environment under dynamic conditions of the entire vehicle, a certain time period should be selected during the vehicle's travel, and the field strength values ​​at intervals should be continuously recorded before and after the selected time points. Simultaneously, the current state of the vehicle and the road conditions on which the vehicle is traveling should also be recorded.

[0094] After setting up the vehicle simulation model and the antenna simulation model, proceed to step S212 to set the materials and mesh.

[0095] In this embodiment, to determine the antenna's performance on the vehicle, the above test results should be combined with the simulation environment. Generally, a vehicle model should be obtained first. Simultaneously, boundary conditions and vehicle material properties should be set. For the antenna model, the antenna model designed in the above steps should be used, and its placement should be consistent with the actual placement position on the vehicle. After setting the above conditions, the field source parameters in the vehicle environment should be configured.

[0096] In this embodiment, for the antenna under test, the antenna test results should be converted into a file recognizable by the simulation software and imported as the simulation results of a single antenna. This allows the original antenna model to be presented in the vehicle environment as a radiation pattern. Simultaneously, to determine the performance changes of the antenna under electromagnetic conditions, the state of the vehicle during the recording period should be recorded. In the simulation software, based on the actual recording, the vehicle is adjusted to different angles to represent different driving states of the vehicle during that period. A road surface should also be set up under the vehicle. An excitation source is set up 0.1m away from the antenna position, and a probe is set up at the antenna for simulation until the field strength at the probe at the antenna position matches the actual measured field strength. At this point, the antenna gain of the entire vehicle is observed, which represents the antenna performance under the current state and at different time periods.

[0097] After setting the materials and grid, proceed to step S213 to set the road surface.

[0098] After setting the road surface, proceed to step S214 and set the excitation source according to the above settings.

[0099] After setting the excitation source according to the above settings, proceed to step S215 to carry out the vehicle-level antenna simulation.

[0100] In the technical solution provided in step S215 of the present invention, in order to perform whole-vehicle simulation, a whole-vehicle model needs to be input. The model format may include three-dimensional formats such as the Standard for the Exchange of Product model data (STP) and the model file format (CATproduct). As preprocessing, it can be imported into preprocessing software to remove small unnecessary parts such as screws. Subsequently, the whole-vehicle model is imported into electromagnetic simulation software. To reduce the amount of computation, the whole-vehicle model can be adjusted to a certain extent using simulation software. By inputting whole-vehicle models under different time periods, different states of the whole vehicle under dynamic environment can be simulated. At the same time, in the simulation software, a cuboid is used to represent the whole vehicle road segment under the whole vehicle model, and the road segment simulation and material settings under the current whole vehicle state are performed to simulate the road segment conditions under the current whole vehicle dynamic environment.

[0101] In this embodiment, based on the gain information of the antenna under test, a first simulation model of the antenna under test and a second simulation model based on the vehicle under test can be determined. The driving data of the vehicle under test under different driving environments can be determined. Finally, based on the determined first simulation model and the above driving data, the performance of the vehicle's antenna under test is tested, and the performance test results can be obtained. This achieves the purpose of testing the performance of the whole vehicle-level antenna under test, thereby solving the technical problem of low accuracy in the performance test of vehicle antennas and thus achieving the technical effect of improving the accuracy of the performance test of vehicle antennas.
