[0048] In the following description, suffixes such as "module", "component" or "unit" used to represent elements are only for the convenience of description of the present invention, and have no specific meaning in themselves. Therefore, "module", "component" or "unit" can be used interchangeably.

[0049] Embodiment 1

[0050] Figure 1 It is a flowchart of the first embodiment of the vehicle emergency call test method of the present invention. A vehicle emergency call test method is applied to the vehicle networking terminal inside the vehicle. This method includes:

[0051] S1. Obtain the audio test environment and audio test requirements of the vehicle;

[0052] S2. Determine the audio test items corresponding to the audio test requirements, and send the audio test items and the audio test environment to the simulation device outside the vehicle to receive the test audio generated after simulation feedback by the simulation device;

[0053] S3. Simulate and execute the emergency call operation of the vehicle according to the test audio, and collect and analyze the obtained test data.

[0054] Optionally, in this embodiment, the simulation device is a computer with an artificial intelligence analysis system. This computer can play sound externally and record sound; connect this computer to the vehicle. On the one hand, it serves as the calling party, and on the other hand, it can also serve as the answering party; connect this computer to the vehicle's TBOX through WiFi, and connect this computer to the call center system provided by the service provider or vehicle manufacturer.

[0055] Optionally, in this embodiment, receive background script control through the above artificial intelligence system, so as to control the TBOX to execute the in-vehicle emergency call; after the call is connected, on the one hand, the voice of the other end emitted from the vehicle speaker can be recorded, and on the other hand, sound can also be played and transmitted to the other end through the vehicle microphone; similarly, the other end also performs the same operation, simulating real people calling each other, so as to simulate listening to the voice, that is, collect audio and record and analyze it; through the above artificial intelligence system, identify problems such as noise, echo, interruption, and volume size during the call, and perform output records for each call, so as to analyze and summarize multiple groups of records within a period of time; further, the above call analysis data and recording data after analysis and summary are forwarded to the TBOX through the above WiFi, and the TBOX sends them to the background server through the cellular network, or the service provider or vehicle manufacturer to which the call center system belongs, for test developers to view; optionally, in this embodiment, the application scenarios of the above test scheme include two types. One is that vehicle manufacturers conduct unit tests and stress tests on the emergency call function during daily operations. The other is that when vehicle manufacturers send vehicles for collision tests, quality monitoring of the emergency call function is carried out.

[0056] Specifically, in this embodiment, first, the audio test environment and audio test requirements of the vehicle are obtained; then, the audio test items corresponding to the audio test requirements are determined, and the audio test items and the audio test environment are sent to an analog device outside the vehicle to receive the test audio generated after simulation feedback from the analog device; finally, the emergency call operation of the vehicle is simulated according to the test audio, and the obtained test data is collected and analyzed. In a specific example, this method mainly involves a vehicle TBOX, a laptop peripheral, and an artificial intelligence voice analysis system. Among them, the TBOX uses a cellular network to interact with the base station externally to complete the task of establishing a voice channel to make a call, interacts with the computer through the WiFi protocol, enables the computer to control the trigger of the emergency call function, and forwards the call analysis record to the cloud server through the cellular network; while the computer provides the ability to record and play back audio, and the artificial intelligence voice analysis system is responsible for simulating calls and analyzing and summarizing voice quality.

[0057] Optionally, in this embodiment, the emergency call function of the vehicle (i.e., eCall) has the characteristics of automatic trigger and precise positioning: on the one hand, without manual operation, in an accident, the driver may be unable to make a call due to injury, and eCall automatically detects the accident and dials through in-vehicle sensors (such as collision sensors, airbag trigger signals) to ensure that the alarm is sent in the first time; on the other hand, precise location information is obtained. eCall uses GPS and mobile networks to send accurate vehicle location, driving direction, collision severity and other data, so that rescue personnel can quickly locate and plan the route, shortening the response time. Further, the emergency call function of the vehicle also has a dedicated emergency line and a standardized protocol: on the one hand, a priority channel, through eCall in regions such as the EU, directly connects to the national emergency service department, skipping the ordinary telephone connection link to ensure that emergency calls are given priority; on the other hand, cross-regional compatibility, that is, for new energy vehicles that often travel across regions, through a standardized protocol (such as sending an XML file containing vehicle information) to ensure the accurate transmission of information during cross-border rescue. Further, the emergency call function of the vehicle can also cooperate with new energy vehicle technologies: on the one hand, in-vehicle system integration, that is, through eCall, it is linked with the in-vehicle electronic systems usually equipped in new energy vehicles (such as BMS battery management system, OTA remote diagnosis). For example, when the battery temperature is detected to be abnormal, an early warning is actively sent, or it is confirmed whether the vehicle is leaking electricity or on fire through remote diagnosis to guide the rescue plan; on the other hand, battery status sharing, that is, through eCall, data such as battery voltage, power, and temperature are sent to the rescue party to help firefighters evaluate risks (such as whether it is necessary to cut off the high-voltage circuit or isolate the vehicle).

[0058] Optionally, in this embodiment, artificial intelligence is applied in the eCall test for acoustic feature analysis, voiceprint and semantic understanding, hybrid models and deep learning, and subjective quality prediction. Specifically: For acoustic feature analysis, key acoustic features in the call are extracted through an AI model. First, speech clarity is detected to check whether the speech becomes blurred due to bandwidth limitations, coding compression, or transmission losses. Second, the background noise level is identified to recognize the intensity and type of environmental noise (such as wind noise, background voices, device noise). Third, echo and latency are analyzed to check whether the echo in the call (such as line echo or speaker feedback) and the end-to-end latency affect real-time communication. Fourth, interruptions or stutters are detected to check for voice incoherence caused by packet loss or jitter in signal transmission. For voiceprint and semantic understanding, first, speaker recognition is performed to verify the identities of both parties in the call through voiceprint features (such as user identity confirmation in a customer service system). Second, semantic analysis is carried out in combination with a natural language processing (NLP) model to determine whether the conversation content fails to convey information correctly due to poor quality (such as key instructions not being correctly understood). For hybrid models and deep learning, first, end-to-end learning is used to directly learn quality features from the original audio using deep neural networks (such as CNN, RNN, Transformer), replacing the traditional step of manually designing features. Second, multimodal fusion is performed by combining visual information (such as the picture quality in a video call) or text information (such as the accuracy of real-time transcribed text) to comprehensively evaluate the overall communication experience. For subjective quality prediction, the mean opinion score (MOS) is predicted through a machine learning model, that is, simulating the subjective experience of humans for call quality. For example, inputting a voice signal and outputting the current score to quantify indicators such as clarity and comfort. The training data comes from the scores given by real users to voice samples of different qualities.

[0059] The beneficial effect of this embodiment is that by obtaining the audio test environment and audio test requirements of the vehicle; determining the audio test items corresponding to the audio test requirements, and sending the audio test items and the audio test environment to a simulation device outside the vehicle to receive the test audio generated after simulation feedback from the simulation device; simulating the execution of the emergency call operation of the vehicle according to the test audio, and collecting and analyzing the obtained test data.
