However, using radio frequency performance testers requires setting numerous judgment thresholds for communication devices under different environments, making the testing process inconvenient and resulting in low efficiency in testing the radio frequency performance of vehicle-mounted communication devices.

Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] Figure 1 This is a flowchart of a testing method for an in-vehicle communication device according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0030] Step S102: Control the target vehicle equipped with the target communication device to be tested and the reference vehicle equipped with the reference communication device to be in the same preset area, and control the target communication device and the reference communication device to receive radio frequency signals.

[0031] The reference communication device is used to indicate a communication device whose device type is the same as the target communication device and whose radio frequency performance reaches the preset radio frequency performance.

[0032] The target communication device mentioned above can refer to the communication device to be tested that is installed on the vehicle. The target communication device may include, but is not limited to, a vehicle terminal (Telematics Box, abbreviated as T-BOX), vehicle navigation device, vehicle wireless network device, etc. The specific target communication device can be determined according to actual needs, and is not limited here.

[0033] The aforementioned reference communication device can refer to a reference device used to test the target communication device. The device type of the reference communication device is the same as that of the target communication device. The reference communication device can be determined according to the specific target communication device, and no limitation is made here.

[0034] The aforementioned preset area can refer to a pre-defined area where the target communication device needs to be tested. There can be one or more preset areas, and the specific location and range of the preset area can be determined according to actual needs. There are no restrictions here. It can test the radio frequency performance of the target communication device mounted on the target vehicle under various environments, and ensure the stability of the radio frequency performance of the target vehicle under various actual environments.

[0035] The aforementioned preset RF performance refers to the RF capabilities that are pre-set to meet RF performance requirements. Preset RF performance may include frequency range, power output, bandwidth, sensitivity, anti-interference capability, etc. The preset RF performance of vehicle communication equipment may include the supported frequency range, transmit power, receive sensitivity, anti-interference capability, etc. By pre-setting these performance requirements and through testing, it is ensured that the vehicle communication equipment can provide stable and reliable communication services. The preset RF performance can be determined according to actual needs and is not limited here.

[0036] The aforementioned radio frequency signal can refer to an electrical signal with a frequency within the radio wave band. The source of the radio frequency signal can be the actual test environment, that is, the actual radio frequency signal source within each preset area, which can be managed by the communication operator. This application is used to test the radio frequency performance of vehicle communication equipment in various actual environments. It can be used for wireless communication and wireless transmission. Radio frequency signals have high frequency and short wavelength, and can propagate in space and carry information.

[0037] In an optional embodiment, in the radio frequency performance testing of vehicle-mounted communication devices, this application proposes a comparative test method to ensure the accuracy and comparability of test results. Specifically, a target vehicle equipped with the target communication device to be tested and a reference vehicle equipped with a reference communication device can be controlled to be in the same preset area, and the target communication device and the reference communication device can be controlled to receive radio frequency signals. In the comparative test, the reference communication device plays a reference role. The device type of the reference communication device is the same as that of the target communication device, and its radio frequency performance reaches a preset radio frequency performance level. By allowing the target communication device and the reference communication device to receive radio frequency signals simultaneously, the performance of the target communication device and the reference communication device can be directly compared. By comparing the quality and stability of the radio frequency signals received by the target communication device and the reference communication device, the performance of the target communication device can be evaluated, and whether it meets the preset radio frequency performance standards can be detected. The above steps can ensure the objectivity and reliability of the test results. Through comparative testing, the radio frequency performance of the target communication device can be evaluated more accurately, potential problems can be discovered and improved, and by comparing with the reference communication device, the performance of the target communication device can be better understood, providing more reliable data and conclusions for radio frequency performance testing.

[0038] Step S104: Obtain the target reception record generated by the target communication device and the reference reception record generated by the reference communication device.

[0039] Among them, the target reception record is used to characterize the reception record generated by the target communication device receiving radio frequency sub-signals of the same frequency band in the radio frequency signal, and the reference reception record is used to characterize the reception record generated by the reference communication device receiving radio frequency sub-signals of the same frequency band.

[0040] The aforementioned radio frequency signals in the same frequency band can refer to radio frequency signals within the same frequency range. In an optional embodiment, during the radio frequency performance testing of in-vehicle communication equipment, a target reception record generated by the target communication device and a reference reception record generated by a reference communication device can be obtained. This can help evaluate the performance of the in-vehicle communication equipment when receiving radio frequency signals. The target reception record is used to characterize the reception record generated by the target communication device when receiving radio frequency sub-signals in the same frequency band of the radio frequency signal. The target communication device will receive radio frequency signals transmitted from other devices or base stations. The radio frequency signals will be demodulated and processed to ultimately form the target reception record. The target reception record may include parameters such as the received signal strength, signal-to-noise ratio, and bit error rate, which are used to evaluate the target communication device. The target communication device's performance in receiving signals is evaluated by comparing the target and reference reception records. The reference reception record characterizes the reception record generated by the reference communication device when receiving radio frequency sub-signals in the same frequency band. During performance comparison, the reference communication device receives radio frequency signals in the same frequency band and generates a reference reception record. By comparing the target reception record and the reference reception record, the performance difference between the target and reference communication devices in receiving signals in the same frequency band can be assessed, thereby helping to optimize the performance of the vehicle-mounted communication device. This application, by obtaining the reception records generated by the target and reference communication devices, can effectively evaluate the performance of the vehicle-mounted communication device in receiving radio frequency signals, thereby guiding performance optimization and improvement efforts.

[0041] Specifically, in the radio frequency performance testing of vehicle-mounted communication devices, this application considers that signals in different frequency bands are affected by different propagation characteristics, interference, and attenuation. If signals from different frequency bands are used for comparison during testing, it is difficult to accurately evaluate the receiving performance of the target communication device. This application proposes to obtain the receiving records generated by the target communication device receiving radio frequency sub-signals of the same frequency band and the receiving records generated by the reference communication device receiving radio frequency sub-signals of the same frequency band. By determining the "radio frequency signal of the same frequency band", it can be ensured that the receiving performance of the target communication device and the reference communication device are compared under the same signal conditions during testing. This allows for a more accurate evaluation of the target device's performance and can also eliminate errors caused by different frequency bands, thereby improving the reliability and accuracy of the test results.

[0042] Step S106: Determine the test results of the target communication device based on the target reception record and the reference reception record.

[0043] The test results are used to indicate whether the radio frequency performance of the target communication device has reached the preset radio frequency performance.

[0044] In one optional embodiment, during the RF performance testing of the vehicle-mounted communication device, a target reception record and a reference reception record can be compared to determine the test results of the target communication device. The target reception record is the data record collected during the testing of the target communication device, while the reference reception record is the data record collected under the same test conditions using a reference device with known performance. By comparing the target reception record and the reference reception record, it is possible to assess whether the RF performance of the target communication device meets the preset RF performance requirements. Specifically, the performance level of the target device can be judged by comparing indicators such as signal strength, signal-to-noise ratio, and bit error rate. If the test results of the target device differ significantly from those of the reference device, it may indicate that the target device has performance problems or needs further optimization. Through the above steps, it can be ensured that the target communication device meets the preset requirements in terms of RF performance, so as to ensure that it can work normally and provide stable communication services in actual use scenarios. By comparing and analyzing the target reception record and the reference reception record, potential performance problems can be identified and resolved in a timely manner, thereby improving the reliability and stability of the vehicle-mounted communication device.

[0045] In this embodiment of the invention, a testing method for a vehicle-mounted communication device is provided. First, a target vehicle equipped with the target communication device to be tested and a reference vehicle equipped with a reference communication device are controlled to be in the same preset area. The target communication device and the reference communication device are controlled to receive radio frequency signals. Then, the target reception record generated by the target communication device and the reference reception record generated by the reference communication device are acquired. Finally, the test result of the target communication device is determined based on the target reception record and the reference reception record. It is noteworthy that this application proposes a comparative testing method to ensure the accuracy and comparability of test results. By having the target communication device and the reference communication device simultaneously receive radio frequency signals, the performance of the target and reference communication devices can be directly compared. By comparing the quality and stability of the radio frequency signals received by the target and reference communication devices, the performance of the target communication device can be evaluated, and whether it meets the preset radio frequency performance standards can be detected. This application proposes to obtain the reception records generated by the target communication device receiving radio frequency sub-signals of the same frequency band and the reception records generated by the reference communication device receiving radio frequency sub-signals of the same frequency band. By identifying the radio frequency signals of the same frequency band, it can be ensured that the reception performance of the target and reference communication devices is compared under the same signal conditions during the test, which can more accurately evaluate the performance of the target device. At the same time, it can also eliminate errors caused by different frequency bands, improve the reliability and accuracy of the test results, and thus solve the technical problem of low efficiency in testing the radio frequency performance of vehicle communication devices in related technologies.

[0046] Optionally, the radio frequency signal includes multiple radio frequency sub-signals in different frequency bands; acquiring the target reception record generated by the target communication device and the reference reception record generated by the reference communication device includes: selecting any one of the multiple radio frequency sub-signals as the target radio frequency sub-signal; acquiring the reception record generated by the target communication device during the reception of the target radio frequency sub-signal to obtain the target reception record; and acquiring the reception record generated by the reference communication device during the reception of the target radio frequency sub-signal to obtain the reference reception record.

[0047] The aforementioned target radio frequency sub-signal can refer to a radio frequency signal under a pre-selected specific frequency band. For example, the target radio frequency sub-signal can be any one of the radio frequency signals under different frequency bands such as N41, B39, B40, B41, GSM900, GSM1800, B1, B5, CDMA, N78, B3, B8 and WCDMA. The target radio frequency sub-signal can be determined according to actual needs, and there is no limitation here.

[0048] In an optional embodiment, during the radio frequency performance testing of the vehicle-mounted communication device, the performance of the target communication device and the reference communication device in receiving the target radio frequency sub-signal can be compared and evaluated. Specifically, considering that the radio frequency signal is composed of multiple radio frequency sub-signals in different frequency bands, one of the radio frequency sub-signals can be selected as the target radio frequency sub-signal for testing. This target radio frequency sub-signal may be a radio frequency band that needs to be focused on during testing, or it may be a typical sample representing the overall radio frequency signal characteristics. In particular, this application can sequentially determine multiple target radio frequency sub-signals according to actual needs, and perform tests sequentially based on each target radio frequency sub-signal to test the vehicle-mounted communication device's performance in each frequency band. The radio frequency performance under different frequency bands can be evaluated by comparing the target and reference communication devices' reception records when receiving the target radio frequency sub-signal. These records can include various parameters and indicators of the device during signal reception, such as received power, signal-to-noise ratio, and bit error rate. By comparing the target and reference reception records, the performance of the target communication device can be assessed, and its condition when receiving the target radio frequency sub-signal can be determined. The above steps evaluate the radio frequency performance of the target communication device by comparing the performance of the target and reference communication devices when receiving specific radio frequency signals. This helps to understand the device's performance under different frequency band signals, guides product design and optimization, and improves the performance and stability of the communication device.

[0049] Optionally, based on the target reception record and the reference reception record, the test result of the target communication device is determined, including: determining the target similarity between the target reception record and the reference reception record; if the target similarity meets the preset similarity condition, the test result is determined to be that the radio frequency performance of the target communication device reaches the preset radio frequency performance; if the target similarity does not meet the preset similarity condition, the test result is determined to be that the radio frequency performance of the target communication device does not reach the preset radio frequency performance.

[0050] The aforementioned preset similarity conditions can refer to a pre-set set of conditions used to determine the difference between the radio frequency performance of the target communication device and the radio frequency performance of the reference communication device. The preset similarity conditions can be determined according to actual needs, and are not limited here.

[0051] In one optional embodiment, during the RF performance testing of the vehicle-mounted communication device, the similarity between the target receiving record and the reference receiving record can be determined. Specifically, by comparing and analyzing the target receiving record and the reference receiving record, the similarity between them can be determined. If the target similarity meets the preset similarity condition, that is, the performance data of the target receiving record and the performance data of the reference receiving record are relatively similar, it can be determined that the RF performance of the target communication device has reached the preset RF performance standard. If the target similarity does not meet the preset similarity condition, that is, the performance data of the target receiving record and the performance data of the reference receiving record are significantly different, it can be determined that the RF performance of the target communication device has not reached the preset RF performance standard. By comparing and analyzing the target similarity between the target receiving record and the reference receiving record, it is possible to effectively determine whether the RF performance of the target communication device meets the preset standard, providing an important reference for subsequent performance evaluation and debugging.

[0052] Optionally, determining the target similarity between the target reception record and the reference reception record includes: obtaining a target reception sub-record in the target reception record corresponding to a first signal receiving end among a plurality of signal receiving ends of the target communication device, wherein the target reception sub-record represents a record generated by the first signal receiving end receiving a target radio frequency sub-signal; obtaining a reference reception sub-record in the reference reception record corresponding to a second signal receiving end among a plurality of signal receiving ends of the reference communication device, wherein the reference reception sub-record represents a record generated by the second signal receiving end receiving a target radio frequency sub-signal, and the second signal receiving end is of the same type as the first signal receiving end; and comparing the target reception sub-record and the reference reception sub-record to obtain the target similarity.

[0053] In an optional embodiment, during the radio frequency performance testing of an in-vehicle communication device, the acquisition and comparative analysis of a target reception record and a reference reception record can evaluate the reception performance of the target communication device. A target reception sub-record corresponding to a first signal receiving end among multiple signal receiving ends of the target communication device is acquired. This target reception sub-record represents the record generated by the first signal receiving end receiving the target radio frequency sub-signal. The reference reception record can refer to the signal record received by the reference communication device. A reference reception sub-record corresponding to a second signal receiving end among multiple signal receiving ends of the reference communication device is acquired. This reference reception sub-record represents the record generated by the second signal receiving end receiving the target radio frequency sub-signal. Specifically, the second signal receiving end and the first signal receiving end are of similar type. To ensure accuracy, the target and reference receiver sub-records must be identical in type. After obtaining them, a comparative analysis is needed. By comparing the similarity between the target and reference receiver sub-records, the receiving performance of the target communication device can be evaluated. The comparison process may include indicators such as signal quality, signal interference, and signal strength. Through comparative analysis, the target similarity can be obtained. The target similarity reflects the difference between the receiving performance of the target device and the reference device, and can evaluate the target device's performance in receiving signals. The above steps, through the acquisition and comparative analysis of the target and reference receiver records, can effectively evaluate the receiving performance of the target device and provide a reference for performance optimization.

[0054] Specifically, in the radio frequency performance testing of vehicle-mounted communication devices, this application compares the data records generated by the same type of signal receivers of the target communication device and the reference communication device. Using the same type of signal receiver for comparison ensures the accuracy and reliability of the test. By testing the same type of signal receiver under the same environmental conditions, the performance differences between the target and reference communication devices can be evaluated more accurately. Using the same type of signal receiver also ensures test consistency and comparability of test data. Using different types of signal receivers for comparison testing may lead to result deviations due to differences in the receivers themselves, making the comparison results unreliable. Using the same type of signal receiver ensures the accuracy and reliability of the test results, allowing for the identification of receivers in the target communication device that achieve or fail to meet preset radio frequency performance, thus enabling the specific determination of the radio frequency performance of each receiver in the target communication device.

[0055] Optionally, the target receiving sub-record and the reference receiving sub-record are compared to obtain the target similarity, including: obtaining the received power comparison result, the signal-to-noise ratio comparison result, and the receiver call comparison result between the target receiving sub-record and the reference receiving sub-record. The received power comparison result represents the comparison between the power of the signal received by the target communication device and the power of the signal received by the reference communication device; the signal-to-noise ratio comparison result represents the comparison between the signal-to-noise interference of the signal received by the target communication device and the signal-to-noise interference of the signal received by the reference communication device; and the receiver call comparison result represents the comparison between the number of calls made by the receiver when the target communication device receives the signal and the number of calls made by the receiver when the reference communication device receives the signal. Based on the received power comparison result, the signal-to-noise ratio comparison result, and the receiver call comparison result, the target similarity is determined.

[0056] In one optional embodiment, during the RF performance testing of the vehicle-mounted communication device, the received power comparison results of the target receiving sub-record and the reference receiving sub-record can be obtained. This can be achieved by comparing the difference between the power of the signal received by the target communication device and the power of the signal received by the reference communication device to evaluate the receiving performance of the target communication device. Higher received power indicates that the target communication device has better receiving performance. The signal-to-noise ratio (SNR) comparison result is used to represent the comparison result between the SNR of the signal received by the target communication device and the SNR of the signal received by the reference communication device. A higher SNR indicates that the target communication device experiences less interference when receiving signals and has better reception quality. The receiver call comparison result is used to represent the comparison result between the number of receiver calls when the target communication device receives signals and the number of receiver calls when the reference communication device receives signals. By comprehensively considering the received power comparison result, the SNR comparison result, and the receiver call comparison result, the similarity between the target communication device and the reference communication device can be determined. This can help evaluate the receiving performance and performance quality of the target communication device and provide a reference for further optimization and improvement of the vehicle-mounted communication device.

[0057] Optionally, the target similarity is determined based on the received power comparison result, the signal-to-noise ratio comparison result, and the receiver call comparison result, including: when the received power comparison result shows that the power similarity between the target received power and the reference received power is greater than a first preset threshold, the target similarity is determined based on the signal-to-noise ratio comparison result and the receiver call comparison result, wherein the target received power is used to represent the power of the target radio frequency sub-signal received by the target communication device, and the reference received power is used to represent the power of the target radio frequency sub-signal received by the reference communication device; when the received power comparison result shows that the power similarity is less than or equal to the first preset threshold, the target similarity is determined to not meet the preset similarity condition.

[0058] In one optional embodiment, during the radio frequency performance testing of the vehicle-mounted communication device, the quality and stability of the radio frequency signal received by the target communication device can be evaluated based on the received power comparison. When comparing the received power, the power similarity between the target received power and the reference received power can be determined. If the power similarity is greater than a first preset threshold, the target similarity can be further determined based on the signal-to-noise ratio (SNR) and the comparison results retrieved by the receiver. The SNR reflects the proportional relationship between signal and noise. By comparing the SNR of the target communication device and the reference communication device, the quality of the target received power can be further evaluated. The comparison results retrieved by the receiver can also provide information about the receiving performance of the target communication device, including comparisons of receiving sensitivity, anti-interference capability, etc. If the power similarity is found to be less than or equal to the first preset threshold in the received power comparison, it can be determined that the target similarity does not meet the preset similarity condition, which indicates that the target communication device has some problems in receiving signals, such as insufficient sensitivity or poor anti-interference capability. At this time, the test results can be further analyzed to find the problem and make corresponding adjustments and improvements to ensure that the performance of the communication device meets the expected requirements.

[0059] Optionally, determining the target similarity based on the signal-to-noise-interference ratio (SNR) comparison result and the receiver call comparison result includes: if the SNR comparison result shows that the SNR similarity between the target SNR and the reference SNR is greater than a second preset threshold, determining the target similarity based on the receiver call comparison result, wherein the target SNR represents the SNR of the target radio frequency sub-signal received by the target communication device, and the reference SNR represents the SNR of the target radio frequency sub-signal received by the reference communication device; if the SNR comparison result shows that the SNR similarity is less than or equal to the second preset threshold, determining that the target similarity does not meet the preset similarity condition.

[0060] In one optional embodiment, during the RF performance testing of an in-vehicle communication device, the performance of the target communication device can be determined by comparing the similarity between a target signal-to-noise ratio (SNR) and a reference SNR. Specifically, the target SNR and the reference SNR can be compared, and the similarity between them can be calculated. The SNR represents the ratio of signal to noise and is used to measure the signal quality received by the communication device. If the SNR comparison result shows that the similarity between the target SNR and the reference SNR is greater than a second preset threshold, the similarity of the target communication device can be further determined based on the comparison result retrieved at the receiving end, and the performance of the target communication device can be further evaluated. Through the above steps, the RF performance of the in-vehicle communication device can be effectively evaluated, and the device performance can be optimized and improved based on the comparison results.

[0061] Optionally, the target similarity is determined based on the receiver call comparison results, including: if the receiver call comparison results show that the number of target receiver calls is the same as the number of reference receiver calls, the target similarity is determined to meet a preset similarity condition, wherein the number of target receiver calls represents the number of receiver calls when the target communication device receives the target radio frequency sub-signal, and the reference signal-to-noise ratio represents the number of receiver calls when the reference communication device receives the target radio frequency sub-signal; if the receiver call comparison results show that the number of target receiver calls is different from the number of reference receiver calls, the target similarity is determined to not meet the preset similarity condition.

[0062] In an optional embodiment, during the radio frequency performance testing of the vehicle-mounted communication device, when comparing receiver calls, it can be determined whether the number of calls made by the target receiver and the number of calls made by the reference receiver are the same. The number of calls made by the target receiver represents the number of calls made by the target communication device when receiving the target radio frequency sub-signal, and the number of calls made by the reference receiver represents the number of calls made by the reference communication device when receiving the target radio frequency sub-signal. When comparing, if the number of calls made by the target receiver is the same as the number of calls made by the reference receiver, it can be determined that the target similarity meets the preset similarity condition, that is, the target communication device performs similarly to the reference device when receiving the target radio frequency signal, and meets the expected performance requirements. If the receiver call comparison result shows that the number of calls made by the target receiver is different from the number of calls made by the reference receiver, further analysis can be performed, and it can be determined that the target similarity does not meet the preset similarity condition, indicating that there is a performance difference or problem in the target communication device when receiving the target radio frequency signal, which requires further debugging and optimization. The receiver call comparison is used to evaluate the performance of the target communication device when receiving radio frequency signals to ensure that it meets the expected requirements and can work normally. Through the testing and analysis of the above steps, potential performance problems can be discovered and resolved in a timely manner, ensuring the normal operation and reliability of the vehicle-mounted communication device.

[0063] Optionally, controlling a target vehicle equipped with the target communication device to be tested and a reference vehicle equipped with a reference communication device to be in the same preset area includes: controlling the target vehicle to start from a first position on a preset circular path and travel along the preset circular path, and controlling the reference vehicle to start from a second position on the preset circular path and travel along the preset circular path, wherein the first position and the second position are in different positions on the preset circular path, and the travel direction of the target vehicle is the same as that of the reference vehicle.

[0064] In an optional embodiment, during the radio frequency performance testing of the vehicle-mounted communication device, the radio frequency performance of a target vehicle and a reference vehicle traveling along a preset circular path within the same preset area can be tested. By controlling the target vehicle and the reference vehicle to start from different positions, the relative position and speed changes between vehicles on a real road can be simulated, thereby more realistically evaluating the performance of the vehicle-mounted communication device. The target vehicle and the reference vehicle can be controlled to travel along the preset circular path, and their travel directions are the same, ensuring that the target vehicle and the reference vehicle maintain a certain relative position during the test, so as to effectively compare the communication performance between the target vehicle and the reference vehicle. Since the target vehicle and the reference vehicle start from different positions, the relative position and mutual influence between different vehicles on a real road can be simulated, thereby more comprehensively evaluating the performance of the vehicle-mounted communication device. Through the above steps, the performance of the vehicle-mounted communication device under different relative positions and speeds can be evaluated, including indicators such as signal transmission quality and communication stability. By comparing the performance of the target vehicle and the reference vehicle, a better understanding of the performance of the vehicle-mounted communication device in complex environments can be achieved, providing a reference for further optimization and improvement of the vehicle-mounted communication device.

Figure 3 As shown, the device includes the following: a control module 302, an acquisition module 304, and a determination module 306.

The reference communication device is used to indicate a communication device whose device type is the same as that of the target communication device and whose radio frequency performance reaches the preset radio frequency performance.

The determination module 306 is used to determine the test result of the target communication device based on the target reception record and the reference reception record. The test result is used to indicate whether the radio frequency performance of the target communication device reaches the preset radio frequency performance.

[0072] The radio frequency signal includes multiple radio frequency sub-signals in different frequency bands; the acquisition module is also used to select any one of the multiple radio frequency sub-signals as the target radio frequency sub-signal; acquire the reception record generated by the target communication device in the process of receiving the target radio frequency sub-signal to obtain the target reception record; and acquire the reception record generated by the reference communication device in the process of receiving the target radio frequency sub-signal to obtain the reference reception record.
