[0023] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0025] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0026] It should be noted that the vehicle-mounted interconnection terminal is an important part of the vehicle networking system. It integrates a variety of communication modules and sensors and is responsible for the information exchange between the vehicle and the outside world. Through the vehicle-mounted interconnection terminal, the vehicle can obtain road condition information, navigation services, remote monitoring and management in real time, and communicate with other vehicles, road infrastructure and cloud service platforms to achieve information sharing and collaboration. The network performance of the vehicle-mounted interconnection terminal directly affects the communication efficiency between the vehicle and the outside world. Efficient network performance can ensure that the vehicle can quickly and accurately obtain and send information, improve the response speed and real-time performance of the vehicle networking system, and in a complex and changing traffic environment, the vehicle-mounted interconnection terminal maintains stable network performance, which can reduce the risk of communication interruption and delay, improve the reliability and stability of the vehicle networking system, and provide users with a better user experience. In summary, the network performance of the vehicle-mounted interconnection terminal is a key factor in the realization of efficient, stable and secure communication in the vehicle networking system. Therefore, in order to ensure the efficient operation of the vehicle networking system and the excellence of the user experience, it is particularly critical and indispensable to conduct a comprehensive and in-depth network performance test of the vehicle-mounted interconnection terminal.

[0027] At present, the network performance test of in-vehicle interconnection terminals mainly relies on laboratory testing, which has the following significant limitations: First, the network environment simulation is insufficient. It is difficult for the laboratory environment to fully reproduce the complex and changeable network environment in the real world, such as signal coverage, interference and network congestion in different scenarios such as urban dense areas, highways, tunnels, and remote areas, resulting in deviations between the test results and the actual application scenarios; Second, the coverage of test scenarios is limited. Due to the limitations of test resources and costs, laboratory testing can often only cover some typical scenarios, and it is difficult to fully evaluate the performance of in-vehicle interconnection terminals in various extreme or special environments; Third, the test flexibility is insufficient. Laboratory test plans are usually relatively fixed, and it is difficult to quickly adjust test parameters and scenarios according to actual needs, which limits the flexibility and adaptability of the test; Fourth, the test cost is high. The laboratory test system requires a large amount of investment, and with the continuous evolution of technology, the cost of updating and replacing test equipment and systems is also high.

[0028] Based on this, the present application provides a vehicle terminal network testing method to solve at least one of the above problems.

[0029] See also Figure 1 , is a flow chart of a vehicle terminal network testing method shown in an exemplary embodiment of the present application. Figure 1 As shown, in an exemplary embodiment, the vehicle terminal network testing method includes at least steps S110 to S140, which are described in detail as follows:

[0030] Step S110, obtain the environmental data and network data of the vehicle terminal when the target vehicle is driving. The environmental data and network data are collected at the same time point. The network data is the data generated by the communication interaction between the vehicle terminal and the core network, which is used to reflect the network performance of the vehicle terminal. Among them, the vehicle terminal is an in-vehicle interconnection terminal, which is an important device for the target vehicle to exchange information with the outside world.

[0031] In one embodiment of the present application, the environmental data and network data of the target vehicle driving in the real environment are collected in real time for the subsequent network performance test of the vehicle terminal. The test is highly flexible and can improve the accuracy and reliability of the test results. Among them, the target vehicle is an intelligent networked vehicle, the core network is an important part of the operator network, which is used to provide stable and efficient communication services for the vehicle terminal, the network data is the information carrier of the communication interaction between the vehicle terminal and the core network, and the transmission quality, speed, delay and other characteristics of the network performance can directly reflect the quality of the vehicle terminal network performance.

[0032] See also Figure 2 , is a schematic diagram of a network test architecture shown in an exemplary embodiment of the present application. Figure 2As shown, the communication module in the vehicle terminal is connected to the core network through the base station in the operator network to realize data interaction and communication between the vehicle terminal and the remote server, cloud platform, other vehicles and infrastructure.

[0033] In one embodiment of the present application, environmental data can be acquired in real time through an environmental perception system and / or a positioning system configured in the target vehicle. Among them, the environmental perception system can be composed of at least a laser radar, a millimeter wave radar and a high-perception camera, and can also be composed of other hardware devices, which are not limited here. An information processing unit is provided in the environmental perception system, which is responsible for receiving the environmental data collected in real time, and processing and analyzing it through an algorithm for realizing environmental recognition, and identifying the environment in which the target vehicle is located. In this way, the real-time and accuracy of environmental recognition are high, and it does not rely on the real-time sensing of high-precision maps. In addition, when the environmental perception system fails, the positioning system can still be used to assist in obtaining environmental data.

[0034] Step S120, identifying the environmental data of the target vehicle, determining the environmental identifier at each time point, and the environmental identifier corresponds to the type of environment.

[0035] In one embodiment of the present application, during actual driving, there are many types of real environments, such as highways, airports, railway stations, viaducts, densely populated urban areas, suburban areas, rural roads, mountain roads, underground parking lots, mountain canyons and tunnels, and the deployment of operator networks in different environments is different. Therefore, in order to conduct targeted network performance tests in different types of environments, different environmental identifiers are used to distinguish different types of environments. For example, if the target vehicle is located in a highway environment, the environmental identifier is api_environment=1, that is, the environment of the highway type corresponds to an environmental identifier of 1; if the target vehicle is located in an airport section, the environmental identifier is api_environment=2, that is, the environment of the airport section type corresponds to an environmental identifier of 2.

[0036] Specifically, the environmental data at each time point is divided into driving environment and weather conditions; the preset mapping table is queried according to the driving environment and weather conditions at each time point, and the environment at different time points is obtained, and the preset mapping table includes the mapping relationship between environmental data and environment; the environmental identification at each time point is generated based on the environment at each time point. For example, if the driving environment of the target vehicle is a highway and the weather condition is sunny, after querying the preset mapping table, the environmental identification is api_environment=11, that is, the environment of the type of highway and sunny weather is 11; if the driving environment of the target vehicle is a highway and the weather condition is light rain, after querying the preset mapping table, the environmental identification is api_environment=12, that is, the environment of the type of highway and light rain is 12.

[0037] In one embodiment of the present application, as the environment of the target vehicle changes continuously during driving, the environmental data and environmental identification at the current time point are updated in real time to ensure that the latest environment of the target vehicle can be reflected in real time. In addition, since the changeable weather and driving environment will affect the network performance, for example, rainy days, snowy days and foggy days may cause signal attenuation and interference; the network coverage may be different in different driving environments. Urban areas may have better network coverage due to dense base stations, while rural roads and remote areas may have insufficient network coverage; in special driving environments such as tunnels and bridges, the signal propagation path may change; even in different driving environments, the difference in vehicle density and driving speed will affect the network performance of the vehicle-mounted interconnection terminal. Therefore, the environmental data combines weather conditions and driving environment, and the scene coverage rate is high in subsequent network performance testing, which significantly improves the comprehensiveness and reliability of the test. For example, if the target vehicle is located in an environment of a highway and an urban highway, the environment identifier is api_environment=101, that is, the environment of an urban highway type has a corresponding environment identifier of 101; if the target vehicle is located in an environment of a highway and a long tunnel, the environment identifier is api_environment=102, that is, the environment of a long tunnel highway type has a corresponding environment identifier of 102; if the target vehicle is located in an environment of a highway and congested road conditions, the environment identifier is api_environment=103, that is, the environment of a highway with congested road conditions has a corresponding environment identifier of 103.

[0038] Step S130 , marking the network data at the same time point according to the environment identifier, generating a network log corresponding to each environment identifier, and recording the network data with the same environment identifier as the same type of network log.

[0039] Specifically, the environment perception system and / or positioning system configured in the target vehicle identifies the environment identifier of each time point based on the environment data at each time point, and then transmits the environment identifier of each time point to the vehicle-mounted terminal via the domain controller in the target vehicle.

[0040] In one embodiment of the present application, Figure 2 As shown, after obtaining the environment identifier, the domain controller in the target vehicle can forward it to the vehicle terminal, mark the network data at the same time point in the vehicle terminal, generate the corresponding network log and store it in the vehicle terminal. For example, if the environment identifier 1 indicates that the environment is a highway, the network log can be named environment 1.log, and if the environment identifier 2 indicates that the environment is an airport section, the network log can be named environment 2.log, and the network logs corresponding to the other environment identifiers can be deduced in the same way.

[0041] In one embodiment of the present application, the domain controller is a domain control node in a modern automotive electrical and electronic architecture, which can collect data from the onboard sensors and share data with other control nodes of the target vehicle, preferably a driving domain controller.

[0042] Step S140, based on the network log corresponding to each environment identifier, obtain test cases under different environment types, run the test cases, and generate a test report.

[0043] Specifically, communication between the vehicle-mounted terminal and the cloud platform is established based on the message middleware; the vehicle-mounted terminal is used to monitor the first request instruction issued by the cloud platform, and the first request instruction carries the environment identifiers and topics to be requested; if the vehicle-mounted terminal subscribes to the topic, the network logs corresponding to the environment identifiers are transmitted to the cloud platform in response to the first request instruction.

[0044] In one embodiment of the present application, Figure 2 As shown in the figure, the vehicle terminal and the cloud platform can communicate through the message middleware and transmit data based on the Hypertext Transfer Protocol (HTTP). MQTT (Message Queuing Telemetry Transport) is a lightweight message protocol that supports the publish / subscribe (pub / sub) model and allows asynchronous message transmission between devices or between devices and servers. In the MQTT architecture, the vehicle terminal subscribes to the topic corresponding to the required service. When the cloud platform needs to obtain the network log in any environment, it will issue a request instruction to the message middleware. The request instruction carries the environment identifier corresponding to the required network log and the topic subscribed by the vehicle terminal. After the vehicle terminal listens to the request instruction that matches the topic it subscribes to, it will parse it and execute the corresponding request.

[0045] In one embodiment of the present application, the vehicle-mounted interconnected terminal uses the HTTPS protocol to transmit the network log to the cloud platform to ensure the security of the data transmission process. In addition, the vehicle-mounted terminal can actively upload the stored network log to the cloud platform regularly to avoid excessive data storage in the vehicle-mounted terminal, resulting in performance degradation, and making the data periodicity of the network log stronger.

[0046] Specifically, the cloud platform is monitored for a second request instruction issued, where the second request instruction carries a time period when the network performance abnormality occurs in the vehicle-mounted terminal, where the time period is the time of the network performance abnormality obtained by analyzing the network data, or is obtained by recording the time when the network performance abnormality occurs when the target vehicle is driving; in response to the second request instruction, the network log within the time period is transmitted to the cloud platform; the network log within the time period is parsed to determine the environment when the network performance abnormality occurs, and use it as the environment to be tested, and continue to test the network performance of the vehicle-mounted terminal under the environment to be tested.

[0047] In one embodiment of the present application, when the network performance of the vehicle terminal is abnormal during the actual driving or testing of the user, it may rely on the driving impression of the user or tester, and can only be located by the time when the abnormality occurs, and it is impossible to clearly and specifically understand the environment, and it is difficult to restore the actual scene where the abnormality occurs. Therefore, in order to simulate and verify the reproducibility of the abnormality and provide support for subsequent optimization, the cloud platform can directly obtain network logs based on the abnormal time period to avoid the impact on irrelevant data, thereby improving the accuracy and efficiency of abnormal location. In addition, the automatic analysis of the network logs within the time period can quickly determine the indicator parameters when the network performance is abnormal, such as network delay, packet loss rate, etc., as well as the environment when the abnormality occurs. In this way, targeted network performance testing can be performed on the abnormal environment to improve the stability and reliability of the vehicle terminal network in this environment.

[0048] In one embodiment of the present application, when the cloud platform needs to obtain the network log of the target vehicle for testing, the request instruction, such as the first request instruction and the second request instruction, also carries the target vehicle identification code (VIN) to ensure that the network log of the target vehicle is obtained.

[0049] In one embodiment of the present application, the network log is transmitted to the cloud platform, including: packaging the network log corresponding to each environment identifier, the packaging operation includes data compression and data encryption; and transmitting the packaged network log to the cloud platform for storage based on the hypertext transfer protocol. In this way, the data volume of the network log is reduced during transmission, and the data integrity and security during the transmission process are ensured.

[0050] Specifically, the network performance test of the vehicle terminal in different environments is completed, including: taking all network logs corresponding to any environment identifier to be tested as the target network logs, and the environment corresponding to the environment identifier as the target environment; running the test case corresponding to the target environment based on the target network log, and obtaining the test results of various network performance indicators under the target environment, the indicators include signal receiving power, signal to interference plus noise ratio, switching success rate, access delay and access success rate; generating a test report based on the test results in all environments.

[0051] In one embodiment of the present application, Figure 2 As shown, a PC (computer) is used to call the interface of the cloud platform to parse the target network log transmitted to the cloud platform, determine the target environment corresponding to the target network log, and then run the test cases in the target environment, so that the test is targeted; and the test cases are automatically run based on the target network log, which reduces manual intervention and improves the test efficiency and accuracy. In addition, the test covers multiple key indicators, which can more comprehensively reflect the network performance of the vehicle terminal in different environments.

[0052] In one embodiment of the present application, testing is performed based on network logs generated by driving a target vehicle in a real environment, which can make the test scenario more in line with the user's usage habits and perfectly compatible with the actual core network environment.

[0053] The vehicle terminal network testing method provided by the present application has the following advantages: first, it can ensure the authenticity and consistency of the environment during the test, thereby avoiding the deviation of the test results caused by environmental differences, and the network data in the same environment is recorded as the same type of network log, so that the vehicle terminal can be tested separately for different environments, improving the scenario coverage and reliability of the test; second, the test cases in the same environment can be directly run based on the network log, reducing the time for repeatedly setting up the test environment and improving the test efficiency; third, by testing the network performance of the vehicle terminal in different environments, the comprehensiveness and reliability of the test are high, which can ensure that users can obtain a stable and reliable network connection experience in various environments, thereby improving the user experience, and when a problem occurs in the network performance in any environment, the network log in the environment can be quickly located to determine the cause of the problem in time; fourth, the testing cost is reduced.

[0054] See also Figure 3 , is a block diagram of a vehicle terminal network testing device shown as an exemplary embodiment of the present application. Figure 3 As shown, in an exemplary embodiment, the vehicle terminal network testing device at least includes an acquisition module 310, an identification module 320 and a marking module 330, and a testing module 340, which are described in detail as follows:

[0055] An acquisition module 310 is used to acquire environmental data of the target vehicle when it is traveling and network data of the vehicle-mounted terminal. The environmental data and the network data are collected at the same time point. The network data is data generated by the communication interaction between the vehicle-mounted terminal and the core network.

[0056] The identification module 320 is used to identify the environmental data of the target vehicle and determine the environmental identification at each time point, and the environmental identification corresponds to the type of environment one by one;

[0057] The marking module 330 is used to mark the network data at the same time point according to the environment identifier, generate a network log corresponding to each environment identifier, and record the network data with the same environment identifier as the same type of network log;

[0058] The test module 340 is used to obtain test cases under different environment types based on the network log corresponding to each environment identifier, run the test cases, and generate a test report.
