As shown in fig. 2, in an exemplary embodiment, the method for constructing the integrated test simulation platform at least includes steps S210 to S240, which are described in detail as follows:

step S210, acquiring performance data of each sensor in the vehicle, and performing virtualization processing on each sensor according to the performance data to obtain each virtualized sensor.

When an integrated test simulation platform is constructed, various data of a vehicle are acquired firstly. Since data of a vehicle is acquired by a sensor, it is necessary to virtualize the sensor at first in an early stage of constructing an integrated test simulation platform. Specifically, performance data of each sensor may be obtained first, where the performance data may visually represent various performance indicators of the sensor, and the performance data includes, but is not limited to, sensitivity, frequency range of use, dynamic range, phase shift parameters, and the like of the sensor. For example, for a displacement sensor, the performance data may be sensitivity, zero temperature drift, output mode, measurement range, sensor gain, dynamic range, and the like. Therefore, for different sensors, the required performance data is different, it should be noted that each sensor may select one or more performance data, and those skilled in the art may adaptively select corresponding performance data according to actual needs according to the type of the sensor, so as to perform virtualization processing on the sensor, where specific performance data is not limited herein. The virtualized sensors obtained by virtualizing the sensors can correctly identify various physical quantities such as pressure, temperature, speed, distance and the like in the simulation environment, can also identify vehicles, pedestrians, static obstacles, traffic infrastructures and the like in the simulation environment, and output related physical data quantities to be provided for a micro-service architecture deployed in an integrated test simulation platform. In order to enable the integrated test simulation platform to be applicable to more types of vehicles, sensors of various vehicles may be virtualized in an initial stage of construction of the integrated test simulation platform, and if sensor performance parameters of two types of vehicles are consistent, the sensors may be simultaneously applied to the two types of vehicles. Therefore, the problem that time and labor are wasted due to the fact that all sensors are required to be subjected to virtualization treatment when a new vehicle type is introduced every time can be effectively solved. Of course, only one sensor of a specific vehicle type may be selected for virtualization, and those skilled in the art may freely select the sensor, which is not limited herein.

Step S220, acquiring the integration function of each electronic controller unit according to the name of each electronic controller unit in the vehicle, integrating each virtualization sensor to the corresponding electronic controller unit, and deploying a micro-service architecture, wherein the integration function of each electronic controller unit corresponds to one or more virtualization sensors.

Because the vehicle is controlled by the ECU, all the behaviors of the vehicle are controlled by the ECU. The ECU is referred to as a drive computer, an electronic control unit, and the like. The ECU is an electronic component which is very central on the vehicle and can monitor various data input by the automobile and various conditions during the running of the vehicle in real time. By integrating each virtualized sensor to the corresponding electronic controller unit, the data acquired by each virtualized sensor can be timely transmitted to the corresponding electronic controller unit for analysis, and the vehicle test is realized. In this embodiment, according to the name of each electronic controller unit in the vehicle, the integrated function of each electronic controller unit and the virtualization sensor required by the electronic controller unit can be queried in a pre-stored information table. Illustratively, in a driving system, the name of the electronic controller unit is a driving electronic controller unit, the corresponding integrated functions of which are to control the speed and direction of travel of the vehicle, and the corresponding virtualized sensors of which are a speed sensor and a direction sensor. The interfaces of the two virtualized sensors are connected with the driving electronic controller unit, so that the data of the virtualized sensors can be transmitted to the driving electronic controller unit. Further, in this embodiment, each electronic controller unit not only has functions in a conventional physical vehicle, but also CAN be virtualized into a form of a plug-in for integration required by container mirror image selection of the microservice architecture, such as 5G network communication, a CAN network controller, various sensor data receiving interfaces, and the like. The micro service container mirror image virtualized by each electronic controller unit node can integrate corresponding virtualized sensors according to different operating systems and basic function interfaces, dynamically generate a service mirror image version, and deploy a micro service architecture according to the service mirror image. In an embodiment of the present invention, the test solution is written into the corresponding container of the microservice architecture in the form of a blueprint. The method is equivalent to the method that embedded business function software is deployed in an electronic controller unit of a certain part of an automobile in actual operation. The test scheme is a preset test for the vehicle, and the test scheme comprises a plurality of test schemes, and each test scheme can test one or more associated performances of the vehicle. Since each time the test solution is developed, a new version of the test solution is generated, and the operator can directly deploy the new test solution to the container of the microservice architecture. Thus, in the container of each micro-service architecture, there are a plurality of different versions of the test protocol, and each test protocol is associated with a function of the electronic controller unit corresponding to that micro-service architecture. Different part interfaces and sensors can have different versions, and an operator can select a test scheme of a required version and dynamically select a test scheme of an integrated corresponding version according to actual test requirements. Through the operation interface, virtual micro-services of each electronic controller unit component can be managed, such as operations of starting, deleting, upgrading blueprint versions of application test schemes, checking micro-service operation conditions, occupying resources by each application module and the like.

And step S230, writing in a corresponding test scheme according to the functions of the micro service architectures, realizing communication among the micro service architectures through a preset communication protocol, and constructing an integrated test simulation platform.

Since there is a container in each microservice architecture for storing the corresponding test scenario. Therefore, when the integrated test simulation platform is constructed, the corresponding test scheme can be written according to the function of each micro-service architecture, namely the function of the corresponding electronic controller unit. Through interconnection and intercommunication among all test schemes, summarization and analysis of test data are realized, and thus an integrated test simulation platform is constructed. The communication between the containers in each micro-service architecture corresponds to the communication between the test solutions in the different electronic controller unit nodes of the automobile in reality. Therefore, in the integrated test simulation platform, not only can interconnection and intercommunication among different test schemes be realized, but also functions of data uploading, issuing, inquiring, controlling and the like between the vehicle-mounted software and the vehicle cloud platform can be simulated.

In an embodiment of the present invention, for a test solution in a single micro service architecture, the data manner acquired by the virtualized sensor may include direct acquisition and indirect acquisition. The direct acquisition can adopt physical data generated for capturing by the virtual sensor and then provided to the service module by the virtual sensor, and the indirect acquisition is to directly send virtual data to a container of the electronic controller unit in a script mode to trigger service.

As shown in fig. 3, fig. 3 is a flow diagram of micro service architecture communication in the embodiment shown in fig. 2 in an exemplary embodiment. In an embodiment of the present invention, the communication protocol is HTTP, and the implementing communication between the micro service architectures through a preset communication protocol includes:

step S310, receiving a connection request sent by one of the micro service architectures;

step S320, judging whether a connection confirmation response is generated within a preset response time length according to the connection request, and sending the generated connection confirmation response to the micro service framework sending the connection request;

step S330, receiving confirmation information sent by the micro service architecture sending the connection request to establish a communication connection with the micro service architecture sending the connection request, where the confirmation information is generated according to the connection confirmation response.

In this embodiment, data transmission is performed between the micro service architectures through an HTTP protocol, and specifically, when communication connection is required between two micro service architectures, one of the micro service architectures serves as a current micro service architecture and receives a connection request sent by the other micro service architecture. The current micro service architecture may generate a connection confirmation response within a preset response duration according to the content of the connection request. And then sending a connection confirmation response to the micro service framework sending the connection request, wherein if confirmation information sent by the micro service framework sending the connection request is received within a preset time length, the two micro service frameworks are indicated to establish communication connection, and data transmission can be realized. If the confirmation information sent by the micro service architecture for sending the connection request is not received within the preset time length, the data transmission is wrong, and therefore the operation needs to be interrupted and the next connection request is waited. Similarly, if the connection confirmation response is not generated within the preset response duration, it indicates that the current micro-service architecture has a problem in network or data transmission, and the operation also needs to be interrupted.

FIG. 4, as shown in FIG. 4, is a flow diagram of the construction of a simulation map in the embodiment shown in FIG. 2 in an exemplary embodiment. In an embodiment of the present invention, after the communication between the microservices is implemented through the preset communication rule, the method further includes:

s410, carrying out simulation modeling according to preset road information, obstacle information, house information and people flow information, and constructing a virtual simulation map;

s420, constructing a whole vehicle model according to the performance parameters of the vehicle;

s430, deploying the whole vehicle model in the simulation map, performing driving operation, and acquiring driving data;

and S440, transmitting the driving data to each micro service architecture so that each micro service architecture controls the whole vehicle model to perform corresponding operation based on the driving data.

In order to make the test result more fit to the reality, a virtual simulation map can be constructed, and the simulation modeling can be carried out on roads, obstacles, characters, houses and the like in the map. And virtually modeling the vehicle by acquiring various performance parameters of the vehicle to construct a whole vehicle model. It can be understood that there may be a plurality of vehicle models, each corresponding to a vehicle type. In actual operation, an operator can select a corresponding whole vehicle model for testing. And deploying the whole vehicle model with the virtualized components in the virtualized simulation map to perform driving motion operation. The simulation of the virtualized sensor is also deployed in a micro-service mode, and the data source of the virtualized sensor is the interaction between the whole vehicle model and elements in the virtualized map. The driving data acquired by the virtualization sensor is transmitted to the corresponding micro service frameworks, and the micro service frameworks perform corresponding driving operation according to the driving data, so that a series of test data can be acquired. Illustratively, in the whole vehicle model, a service function module and a virtualized sensor data receiving function are integrated in a virtual machine of each component node, the whole vehicle model simulates moving driving in a virtualized map, in the process, the whole vehicle model interacts with various elements in the virtual simulation map, and generated physical signals can be captured by the virtual sensor in each virtual machine of the whole vehicle model and transmitted to a corresponding container in a micro-service architecture. The container can perform corresponding operations according to the received physical signals, or interact with containers in other micro-service architectures, or interact with the vehicle cloud platform. The scene can be applied to algorithm testing of intelligent driving, can also be applied to testing of vehicle-mounted software under the conditions of simulating impact and collision, and can reduce hardware resource loss in actual testing. The mode of transmitting data to the electronic controller unit can adopt a publishing mode, and the electronic controller unit can also selectively subscribe the data of the target virtual sensor, so that the effective transmission of the data is realized. The virtual simulation map is created, the virtual sensor is built, the whole vehicle model is loaded in the simulation map, the processes of driving movement and the like are simulated, and the service software flow data in the simulation process are output, so that the final test result is closer to a real scene, and the error rate of the test is reduced.

Further, in order to facilitate an operator to observe various data more intuitively, in an embodiment of the present invention, the integrated test simulation platform is a visual operation interface. The whole vehicle model is composed of a plurality of component models. Each component can be split, so that during actual testing, an operator can directly select a basic functional component and a virtual sensor component which are required to be integrated on a target component according to the target component which needs to be tested, and dynamically generate a container mirror image version for deployment. And observing a test result through an integrated test simulation platform. Various virtualization capacity plug-ins can be selectively integrated through plug-in type virtualization of various basic capacities of vehicle-mounted electronic controller unit components and container virtualization of various components of the whole vehicle, and container images representing vehicle-mounted electronic controller unit nodes are dynamically generated. And thus can be adapted to a variety of different blueprint versions. After the communication connection between different micro service architectures is established, an automatic test flow can be established in the micro service architecture with the user interaction application software deployed, man-machine interaction is simulated, and the service flow between vehicle-mounted nodes in actual operation is simulated by triggering the interaction process of containers between different micro service architectures. By establishing the automatic testing process, the workload of testing and acceptance can be effectively reduced in the subsequent process of upgrading and expanding the functions of each service module.

As shown in FIG. 5, FIG. 5 is a flow diagram of a testing process in the embodiment shown in FIG. 2 in an exemplary embodiment. In an embodiment of the present invention, the process of testing by using the integrated test simulation platform includes:

s510, inputting test requirements into the integrated test simulation platform, and reading data required by preset software test requirements;

s520, searching the electronic controller unit corresponding to the data from a pre-stored data table according to the data required by the test requirement, and sending a data acquisition request to the corresponding electronic controller unit;

s530, receiving data sent by each electronic controller unit within preset time, judging whether each data meets preset standards, and completing the test when the data meets the standards.

When the integrated test simulation platform is used for software test, specific test requirements are input into the integrated test simulation platform by an operator, and the integrated test simulation platform can automatically read data required by the test requirements. And the operator can select corresponding test data in the integrated test simulation platform through a pull-down menu and then start testing through the integrated test simulation platform. During testing, after the integrated test simulation platform reads required data, the name of the electronic controller unit related to the data is inquired from a data table prestored in the platform, and a data acquisition request is sent to the electronic controller unit to indicate that the electronic controller unit needs to operate so as to acquire the corresponding data. And after receiving the request, the electronic controller unit acquires corresponding data by controlling the operation of the whole vehicle model and sends the data to an interface of the integrated test simulation platform within preset time. And the judgment unit of the integrated test simulation platform judges whether the data meet the test requirements of operators or not and determines whether the data meet the standards or not. And if all the data meet the test requirements, the standard is met, the test is completed, and a test completion report is pushed to an operator, wherein the report contains all the data of the test. In an embodiment of the present invention, after determining whether each data satisfies a preset standard, the method further includes: if one data does not meet the preset standard, test failure information is returned, and warning information is sent out on the integrated test simulation platform. Meanwhile, a test failure report can be pushed to an operator, wherein the test failure report can comprise data of test failure and judgment of a possibly caused reason.

It should be noted that the present invention can be implemented in many different forms and is not limited to the embodiments described herein, such as may be based on different operating systems: including but not limited to linux, qnx, and other operating systems, based on different hardware platforms: including but not limited to x86, xavier, orin, etc. hardware platforms.

According to the invention, after the performance data of each sensor is obtained, the sensors can be virtualized, so that the virtualized sensors are obtained. In order to associate the virtualized sensors into the vehicle model.

The interference of a hardware environment is avoided, the problem positioning is more efficient, and a more sufficient test scene can be provided by the support of an automatic test case. The whole vehicle model is combined with physical simulation, the motion driving of the whole vehicle model in a virtualized map is simulated, physical signals generated in the process are transmitted to corresponding business modules in the micro-service architecture, and the interaction flow among the business modules is triggered. The driving simulation of the whole vehicle model under the virtual map can also simulate the motion scene under some extreme conditions, reduce the times of real objects and artificial driving and save the development cost. Further, in the application, a visual integrated test simulation platform is created based on the whole vehicle model, and the service module is deployed in the micro-service container corresponding to the electronic controller unit. For the electronic controller units on different CAN buses, the micro-services corresponding to the electronic controller units CAN be positioned in different network segments, and the interconnection and intercommunication of information in different network segments CAN be realized.
