Fig. 1 is an environmental schematic diagram of an implementation of a method for testing a cloud delay time of uploading automobile data according to an exemplary embodiment of the present application. As shown in fig. 1, when the vehicle 110 uses the vehicle-mounted sensor such as radar or a camera to obtain the environmental information around the vehicle 110 and the driver to operate during the driving process, the data information fed back by the internal system of the vehicle is transmitted and buffered by the data processing module 120, and the data processing module 120 uploads the buffered vehicle data uploaded by the vehicle 110 to the cloud 130 such as TSP (Telematics Service Provider, internet of vehicles service background). The cloud 130 shown in fig. 1 may be an automobile telematics service provider, or may be a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), and basic cloud computing services such as big data and artificial intelligence platforms, which are not limited herein.

Obviously, the performance requirement of the vehicle data uploading cloud end during actual operation of a driver cannot be met through the single scene and the single event test, and the accuracy of the data uploading cloud end delay time test cannot be guaranteed. In order to solve these problems, embodiments of the present application provide a method, a device, equipment and a medium for testing a cloud delay time of uploading automobile data, and the embodiments will be described in detail below.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for testing a cloud delay time of uploading automobile data according to an exemplary embodiment of the present application. In some embodiments, the method may be applied to the implementation environment shown in FIG. 1 and executed in particular by the data processing module 120 in the implementation environment. It should be understood that the method may be adapted to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and the implementation environments to which the method is adapted are not limited by the present embodiment.
For example, a navigation SDK (Software Development Kit, a software development kit, a development tool set when application software is built for a specific software package, a software framework, an operating system, etc.) may be installed in the data processing module 120 applicable to the method for testing the cloud delay time of uploading automobile data disclosed in the present embodiment, and the method disclosed in the present embodiment is specifically implemented as one or more functions provided by the SDK externally.
As shown in fig. 2, in an exemplary embodiment, the method for testing the delay time of uploading the vehicle data includes at least steps S210 to S280, which are described in detail as follows:
and step S210, finishing the registration of the Internet of vehicles and the inspection of the test vehicles.
Firstly, it should be noted that some checks including registration of the internet of vehicles, confirmation of the safety state of the test vehicle, and confirmation of the software and hardware version and functions of the associated controller need to be completed before the test of the cloud delay time for uploading the vehicle data is performed. The internet of vehicles registration is to have a license for uploading the vehicle data to the TSP. The registration of the internet of vehicles requires the addition of test vehicles for which the safety state is confirmed to be good. The test vehicle state is detected completely, the test vehicle state comprises a software and hardware version of an associated controller and function confirmation, wherein the software and hardware version of the associated controller and the function confirmation comprise an MCU (Microcontroller Unit, microcomputer), and the confirmation mainly aims at data acquisition and transmission and control of other controllers. The associated controller software and hardware version and function validation also includes a Front Camera (FC) function for capturing and recording the environment in Front of the vehicle 110 shown in fig. 1. The software and hardware version of the associated controller and function confirmation further comprise a function of confirming a vehicle-mounted entertainment terminal (for example, the vehicle-mounted entertainment terminal can be expressed as THU), the vehicle-mounted entertainment terminal provides a remote communication interface for the whole vehicle, the functions of communication function, positioning capability, OTA (Over-the-Air Technology) upgrading, vehicle wireless communication Technology and the like are provided, the vehicle-mounted entertainment Terminal (THU) in the embodiment comprises the vehicle-mounted entertainment terminal (for example, the vehicle-mounted entertainment terminal can be expressed as THU (HU)) and a vehicle-mounted communication base terminal (for example, the vehicle-mounted entertainment terminal can be expressed as THU (4G)), the THU (HU) realizes a main application program function of the THU, and the THU (4G) realizes a vehicle-mounted communication function. The associated controller hardware and software version and function validation also includes the function of validating the ADS (Autonomous Driving System, autopilot system) and the APA (Auto Parking Assist, autopilot assist system). The inspection of the test vehicle ensures the safety and accuracy of the test.
Step S220, an event trigger list is obtained.
The event trigger list of the vehicle 110 shown in fig. 1 is set according to different vehicle type projects, and the event trigger list includes information of events such as starting the vehicle 110, instantaneous acceleration running of the vehicle 110, instantaneous braking of the vehicle 110, passing of the vehicle 110 through an arch bridge, turning of the vehicle 110, deceleration stopping of the vehicle 110, and the like, so that the comprehensiveness of trigger event coverage is ensured when the vehicle 110 is tested.
Step S230, setting various test scenes.
In the set various test scenes, the difference of the intensity of the network signals, the load of the network uplink transmission channel and the load of the vehicle-mounted entertainment terminal can cause the difference of the test results of the cloud delay time of the uploading of the vehicle data, and the effective coverage of the cloud scene of the closed-loop data uploading of the intelligent driving file is realized by combining the scenes of the intensity of the network signals, the load of the network uplink transmission channel and the load of the vehicle-mounted entertainment terminal, and the test in the scenes is set, so that the accuracy and the comprehensiveness of the cloud test time of uploading are ensured. Various test scenarios, for example, the first test scenario includes weak network signals, low load of a network uplink transmission channel, and low load of a vehicle-mounted entertainment terminal. For example, the second test scenario includes weak network signals, low network uplink transmission channel load, and high vehicle entertainment terminal load. For example, the third test scenario includes weak network signals, high network uplink transmission channel load, and high vehicle entertainment terminal load. For example, the fourth test scenario includes weak network signals, high network uplink transmission channel load, and low vehicle entertainment terminal load. For example, the fifth test scenario includes strong network signals, low load of the network uplink transmission channel, and low load of the vehicle-mounted entertainment terminal. For example, the sixth test scenario includes strong network signals, low load on the network uplink transmission channel, and high load on the vehicle entertainment terminal. For example, the seventh test scenario includes strong network signals, high network uplink transmission channel load and low vehicle entertainment terminal load. For example, the eighth test scenario includes strong network signals, high network uplink transmission channel load and high vehicle entertainment terminal load.
When setting the strength of the network signal, the provider information of the 4G internet of things card of the vehicle 110 shown in fig. 1 needs to be checked first, and then the test location of the strength of the network signal is selected according to the provider of the 4G internet of things card of the vehicle 110. The load of the network uplink transmission channel is determined by the bandwidth of the uplink transmission channel, the larger the bandwidth is, the smaller the load of the network uplink transmission channel is, the smaller the bandwidth is, and the higher the load of the network uplink transmission channel is, wherein the bandwidth of the uplink transmission channel can be distributed by an MCU (Microcontroller Unit, microcomputer). The load of the in-vehicle entertainment terminal is determined according to the magnitude of the controller output signal corresponding to the application program loaded on the vehicle 110.
Step S240, triggering corresponding events according to the event trigger list in various test scenes.
When triggering the corresponding event, two working conditions, such as a simulated single event triggering working condition and a simulated user actual scene working condition, need to be set in advance. For example, under the simulated single event triggering working condition, the set test scene is a first test scene including weak network signals, low load of a network uplink transmission channel and low load of a vehicle-mounted entertainment terminal. Then in a first test scenario, the driver triggers corresponding events such as sudden braking, sharp turning and acceleration, etc., sequentially through the CANOE (Controller Area Network Open environment, car bus device) according to the event trigger list, wherein each event within each scenario triggers the test at least 3 times, for example.
Step S250, test data in a period of time before and after the triggering of the corresponding event is obtained.
The data processing module 120 shown in fig. 1 collects test data packets and files for a period of time before and after occurrence of a corresponding event according to a collection rule of the corresponding event. In some embodiments, the test data includes test packets, such as TCP (Transmission Control Protocol ) packets, and test files. The test files comprise event-related CAN message files, event-related video files and FC image data files.
Step S260, the message of the corresponding event is obtained, and the data pulling instruction information of the corresponding event is obtained.
The data processing module 120 shown in fig. 1 caches test data in a period of time before and after the corresponding event is triggered in the data processing module 120, and sends a message of the corresponding event to the cloud 130, for example, the TSP, and the cloud 130, for example, the TSP, actively or passively sends a test file or a test data packet pulling instruction to the data processing module 120 according to a file pulling rule of the corresponding event after obtaining the message of the corresponding event.
Step S270, according to the message of the related event and the data pulling instruction information of the corresponding event, the test data in a period of time before and after the corresponding event is triggered is uploaded to the cloud.
After the data processing module 120 shown in fig. 1 obtains the information of the test data packet or the test file pulling instruction sent by the cloud end 130, for example, the TSP, the test data packet or the test file cached in the data processing module 120 is uploaded to the cloud end, for example, the TSP, so as to complete uploading of the test data of the automobile to the cloud end. By acquiring the information of the message of the corresponding event and the information of the data pulling instruction of the corresponding event, the accuracy of uploading the measured data to the cloud can be improved.
Step S280, obtaining the delay time of uploading the test data to the cloud.
The delay time of uploading the test data to the cloud in this embodiment is a time interval from when the data pulling instruction information sent by the cloud, such as TSP, actively or passively, is obtained to when the test data is successfully uploaded to the cloud. Because each event in each scene in step S240 triggers a test at least for 3 times, the test time acquired by each corresponding event in each scene is for example 3 times, and the test time obtained by calculating the obtained multiple test times is compared with the preset time value to determine whether the vehicle performance target, i.e. the vehicle data uploading cloud delay time, is qualified, if the test time value is less than or equal to the preset time value, the vehicle performance target, i.e. the vehicle data uploading cloud delay time, is qualified, and if the test time value is greater than the preset time value, the vehicle performance target, i.e. the vehicle data uploading cloud delay time, is not qualified. And the performance of software and hardware in the vehicle can be optimized by analyzing the working conditions, the scenes and the test data triggered by the corresponding events.
Fig. 3 is a flowchart illustrating a testing method for simulating a cloud delay time of uploading automobile data under a single event triggering condition according to an exemplary embodiment of the present application. The test method for simulating the cloud delay time of uploading automobile data under the single event triggering condition can comprise steps S310 to S370, and is described in detail as follows:
step S310, according to the event list definition of the vehicle type project of the test vehicle, acquiring an event trigger list.
Different vehicle model items include different event list definitions, and event trigger lists are set according to the event list definitions.
Step S320, obtaining the test sites of the network signal intensity.
The cloud end for uploading the automobile data needs a network to transmit the data, the network is provided by a 4G (fourth generation mobile information technology) internet of things card of the automobile 110 shown in fig. 1, when a place for acquiring the strength of a network signal is acquired, a provider of the 4G internet of things card of the automobile needs to be confirmed first, and then a test place related to the strength of the network signal is selected according to the place for providing the strength of the network signal by the provider of the internet of things card.
Step S330, obtaining the load high-low state information of the network uplink transmission channel and obtaining the load high-low state information of the vehicle-mounted entertainment terminal.
The load of the uplink transmission channel of the network is determined by the bandwidth of the uplink transmission channel, the larger the bandwidth is, the smaller the load of the uplink transmission channel of the network is, the smaller the bandwidth is, and the higher the load of the uplink transmission channel of the network is, wherein the bandwidth of the uplink transmission channel can be distributed by an MCU (Microcontroller Unit, microcomputer). The load of the vehicle-mounted entertainment terminal is determined according to the output signal of the controller corresponding to the application program loaded by the vehicle 110, namely, the load of the vehicle-mounted entertainment Terminal (THU) is realized according to the number of application programs running in the background of the vehicle-mounted entertainment terminal, the number of application programs running in the vehicle-mounted entertainment Terminal (THU) is large, the load of the vehicle-mounted entertainment Terminal (THU) is high, the number of application programs running in the vehicle-mounted entertainment Terminal (THU) is small, and the load of the vehicle-mounted entertainment Terminal (THU) is low.
Step S340, in the scene of the combination of the high or low load of the network uplink transmission channel and the high or low load of the vehicle-mounted entertainment terminal, according to the event trigger list, triggering a single corresponding event.
The combined scenes are, for example, eight test scenes set in step 230, so that effective coverage of the intelligent driving file closed-loop data uploading cloud scene is realized, and the combined scenes are set to be tested in a plurality of scenes, so that accuracy and comprehensiveness of uploading cloud test time are ensured. And then triggering single corresponding events for multiple times through CANOE according to the information of the event trigger list.
Step S350, test data in a period of time before and after the single corresponding event is triggered is obtained.
The data processing module 120 shown in fig. 1 collects test data packets and files for a period of time before and after occurrence of a corresponding event according to a collection rule of the corresponding event. Wherein the file comprises an event-related CAN message file, an event-related video file and an FC image data file
Step S360, the test data in a period of time before and after the single corresponding event is triggered to upload to the cloud.
The data processing module 120 shown in fig. 1 caches test data in a period of time before and after the corresponding event is triggered in the data processing module 120, and sends a message of the corresponding event to the cloud 130, for example, the TSP, and the cloud 130, for example, the TSP, actively or passively sends a test file or a test data packet pulling instruction to the data processing module 120 according to a file pulling rule of the corresponding event after obtaining the message of the corresponding event. After the data processing module 120 shown in fig. 1 obtains the test data packet or the test file pulling instruction sent by the cloud end 130, for example, the TSP, the test data packet or the test file cached in the data processing module 120 is uploaded to the cloud end, for example, the TSP, so as to complete uploading of the test data of the automobile.
Step S370, obtaining the delay time of uploading the test data to the cloud in a period of time before and after the single corresponding event is triggered.
The delay time of uploading the test data to the cloud in a period of time before and after the single corresponding event is triggered in the embodiment is a time interval from the time when the data pulling instruction information sent by the cloud, such as the TSP, actively or passively is acquired to the time when the test data is successfully uploaded to the cloud. And the acquired delay time of the test data uploading cloud needs to be compared with a preset time value to judge whether the data uploading cloud performance of the vehicle is qualified or not.
Fig. 4 is a flowchart illustrating a test method for simulating a cloud delay time of uploading automobile data under a condition of an actual driving scenario of a user according to an exemplary embodiment of the present application. The test method for simulating the cloud delay time of uploading the automobile data under the actual driving scene working condition of the user can comprise the following steps S410 to S460, which are described in detail:
step S410, a prescribed route and a prescribed time period for the test vehicle to travel are acquired.
In the working condition test of simulating the actual driving scene of the user, the specified line and the specified driving time length of the test vehicle are required to be acquired so as to improve the integrity and accuracy of data collection. The prescribed routes include urban adaptive driving routes, suburban adaptive driving routes and highway adaptive driving routes.
Step S420, obtaining high-load state information of the vehicle-mounted entertainment terminal.
After the single event triggering working condition test is completed, the vehicle is continuously and normally driven, and during driving, the vehicle-mounted entertainment terminal is in a high-load state, so that the background actual condition of an application program in actual driving operation of a user is realized.
Step S430, under the condition that the vehicle-mounted entertainment terminal is in a high-load state and the intelligent driving function is in an on state, the test vehicle finishes running of a specified line and a specified duration.
