During the development and self-testing stage of the air conditioning application, it is necessary to conduct joint debugging with the vehicle air conditioning controller to ensure the correct implementation of the function. However, since the vehicle air conditioning controller is usually in the development stage or the hardware resources are limited, developers often cannot obtain the actual controller for debugging in time, which affects the progress of the entire project. Therefore, being able to develop and test air conditioning applications in the absence of hardware support has become an urgent need in the development of automotive electronic systems.

[0003] Currently, developers usually perform functional testing and debugging through actual in-vehicle air conditioning controller hardware. This approach requires the development team to have access to the controller hardware during the debugging phase so that the correctness of the function can be verified through communication with the air conditioning application. The actual hardware provides test conditions consistent with the in-vehicle environment and is a direct means of verifying the behavior of the air conditioning application.

[0004] However, there are many limitations to relying on actual hardware for testing. First, during the vehicle development process, the material supply of the vehicle air conditioning controller may be insufficient, and it itself is also under development, which greatly reduces the availability of debugging hardware. Second, the controller hardware resources are limited, and multiple development teams may need to share them, further exacerbating the scheduling conflicts between development and testing.

[0054] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0055] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0056] With the continuous development of automotive electronic technology, the vehicle air conditioning system, as an important part of vehicle comfort, has received more and more attention. During the development and self-testing stage of the air conditioning application, it is necessary to conduct joint debugging with the vehicle air conditioning controller to ensure the correct implementation of the function. At present, developers usually perform functional testing and debugging through the actual vehicle air conditioning controller hardware. This method requires the development team to obtain the controller hardware during the debugging stage so that the correctness of the function can be verified by communicating with the air conditioning application. The actual hardware provides test conditions consistent with the vehicle environment and is a direct means to verify the behavior of the air conditioning application. However, there are many limitations to relying on actual hardware for testing. First, during the vehicle development process, the material supply of the vehicle air conditioning controller may be insufficient, and it is also under development, resulting in a significant reduction in the availability of debugging hardware. Second, the controller hardware resources are limited and multiple development teams may need to share, further exacerbating the scheduling conflict between development and testing. In addition, hardware debugging often requires a long wait, affecting development efficiency.

[0057] The main solution of the embodiment of the present application is: first, obtain the operation information from the test interface generated by the simulation, which can provide the necessary input data for the subsequent simulation operation. These data represent the specific instructions or operations of the user interacting with the vehicle air-conditioning controller. Then, according to the obtained operation information, the corresponding CAN signal data that can simulate the actual operation of the vehicle air-conditioning controller is generated to provide simulation support for the data exchange during the communication process. Then, these CAN signal simulation data are parsed and converted into corresponding CAN communication message data to ensure that the data format and content are consistent with the real CAN communication. Finally, the generated CAN communication message data is sent to the air-conditioning application, so that the air-conditioning remote control displays the corresponding operation information according to these data, and realizes the verification and testing of the air-conditioning application function. The whole process performs effective functional verification tests on the air-conditioning application without relying on actual hardware, which improves development efficiency.

[0058] It should be noted that the execution subject of the embodiment of the present application may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a software simulation device of a vehicle air conditioning controller, etc. The following takes a terminal loaded with a software simulation tool of a vehicle air conditioning controller as an example to illustrate this embodiment and the following embodiments.

[0059] Based on this, the embodiment of the present application provides a software simulation method for a vehicle air conditioning controller, referring to Figure 1 , Figure 1 This is a flow chart of a first embodiment of a software simulation method for a vehicle air-conditioning controller of the present application.

[0060] In this embodiment, the software simulation method of the vehicle air conditioning controller includes steps S10 to S40:

[0061] Step S10, obtaining first operation information input based on a test interface, wherein the test interface is an operation interface generated by simulating the function of a vehicle air conditioning controller;

[0062] It should be noted that the test interface refers to an operation interface generated by simulating the vehicle air-conditioning controller, which is used to simulate and test the functions of the vehicle air-conditioning controller. This interface is simulated by simulating the vehicle air-conditioning controller and does not rely on the actual vehicle air-conditioning controller hardware. The first operation information refers to the operation instructions or operation actions entered by the user on the test interface, such as clicking a button, adjusting parameters, etc. Simulating the vehicle air-conditioning controller refers to using software tools to simulate the various functions and behaviors of the vehicle air-conditioning controller.

[0063] It is understandable that in a simulation software, the operation information input by the user is obtained on the operation interface generated by simulating the function of the vehicle air-conditioning controller. Specifically, the simulation software simulates the various functions of the vehicle air-conditioning controller and displays these functions on the test interface. The user operates the air-conditioning controller function through this interface, such as clicking a button or adjusting the temperature, etc. The software will record these operations and convert them into "first operation information", that is, a record of the specific instructions or actions performed by the user on the test interface. This operation information will be used for signal generation and communication processing in subsequent steps. For example, adjust the air-conditioning temperature to 20 degrees. For ease of understanding, this example will be used later.

[0064] As an example, before obtaining the first operation information input based on the test interface, it also includes: connecting with the CAN communication device; after connecting with the CAN communication device, importing the communication matrix information through the CAN communication device; generating an operation interface that simulates the function of the vehicle air-conditioning controller according to the communication matrix information. Among them, the CAN communication device refers to a device or module connected to the CAN bus of the vehicle system, which is responsible for the implementation and management of the CAN communication protocol. Communication matrix information refers to a data structure or configuration file that describes the communication rules and protocols between various control units in the vehicle system. The communication matrix information includes detailed information such as the identifier (ID) of each CAN message, the format of the data frame, and the sending cycle. This information is very important for software simulation tools because they define how the simulation software simulates and generates data compatible with the CAN bus communication in the actual vehicle system.

[0065] Specifically, this step describes the preparation stage in the vehicle air conditioning controller software simulation system. First, the simulation software is connected to the CAN communication device inside the vehicle system to ensure that the CAN communication data can be obtained and sent normally. Then, the pre-prepared communication matrix information is imported into the simulation software through the connected CAN communication device. These communication matrix information describes in detail the structure, content and sending rules of various CAN communication messages. Finally, the simulation software generates an operation interface that simulates the functions of the vehicle air conditioning controller based on the imported communication matrix information. This interface includes various function buttons and operation options of the simulated vehicle air conditioning controller for developers to simulate testing and debug vehicle air conditioning applications.

[0066] Step S20, generating corresponding first CAN signal simulation data according to the first operation information;

[0067] It should be noted that the first CAN signal simulation data refers to the simulated CAN signal data generated according to the first operation information input by the user in the test interface. Specifically, these data are virtual CAN signal data generated according to the vehicle air-conditioning controller functions simulated by the simulation software and user operations, which are used to simulate the CAN signals sent by the actual controller during operation. These simulated data will be sent to the air-conditioning application so that the air-conditioning application can perform corresponding operations and display functions based on the received data. Among them, the CAN signal refers to the signal of the Controller Area Network. It is a serial communication protocol commonly used in the field of vehicles and industrial control, and is used for data communication and transmission between different control units. CAN signals are transmitted through the CAN bus, including information such as sensor data and control commands.

[0068] It is understandable that, according to the operation information input by the user on the test interface of the simulated vehicle air conditioning controller, the corresponding virtual CAN signal simulation data is generated by the software. These data reflect the operations performed by the user on the interface, such as adjusting the air conditioning temperature to 20 degrees, and the software simulates and generates appropriate CAN communication message data based on the operation information. These simulation data will be sent to the air conditioning application to trigger and display the corresponding air conditioning function operation.

[0069] Step S30, parsing the first CAN signal simulation data to generate corresponding first CAN communication message data;

[0070] It should be noted that the first CAN communication message data refers to the specific CAN communication message obtained after parsing the first CAN signal simulation data generated by the simulation software. Specifically, these messages include information such as the ID (identifier) ​​of the CAN message, data frame content, and transmission cycle.

[0071] It can be understood that this step is to parse the first CAN signal simulation data generated by the simulation software to generate actual CAN communication message data. The parsing process converts the simulation data into a specific data format that complies with the CAN bus protocol based on the pre-defined communication matrix and protocol specifications, including information such as the CAN message ID, data frame content, and transmission time interval. These generated CAN communication message data will be sent to the air conditioning application so that it can perform corresponding operations and function displays based on the received signal.

[0072] As an example, the software simulation system of the vehicle air-conditioning controller includes an air-conditioning application, an intelligent cockpit controller and a CAN communication device that communicate in sequence; sending the first CAN communication message data to the air-conditioning application includes: sending the first CAN communication message data to the first CAN communication device, sending the first CAN communication message data to the intelligent cockpit controller through the first CAN communication device, and sending the first CAN communication message data to the air-conditioning application through the intelligent cockpit controller.

[0073] Among them, the smart cockpit controller refers to the control unit in the vehicle system that is responsible for managing and controlling various cockpit functions. It exchanges and communicates data with other control units through the CAN communication device. This step describes the communication process between the various components in the vehicle air-conditioning controller software simulation system. The system includes an air-conditioning application, a smart cockpit controller, and a CAN communication device, which exchange and collaborate data in sequence. Specifically, first, the simulation software sends the generated first CAN communication message data to the first CAN communication device, through which the data is transmitted to the smart cockpit controller. The smart cockpit controller receives and parses these CAN communication message data, and then performs corresponding operations according to the instructions and parameters therein, and finally sends the processed data back to the air-conditioning application. This process ensures that the simulation software can accurately simulate and verify the functions of the vehicle system, including important operations such as air-conditioning control.

[0074] Step S40: sending the first CAN communication message data to an air-conditioning application, so that the air-conditioning application displays corresponding operation information according to the received first CAN communication message data.

[0075] It should be noted that the air conditioning application refers to the software program in the vehicle system that is responsible for controlling and managing the air conditioning function. It receives signal data from the CAN bus and performs corresponding operations based on these data, such as controlling the air conditioning temperature, wind speed and other functions. The display of operation information refers to the air conditioning application displaying the corresponding operation information in a user-visible form based on the received CAN communication message data, such as displaying the current temperature setting, wind speed adjustment and other operation results or status on the display screen. The data exchange and function execution process between the vehicle air conditioning controller and the air conditioning application through the CAN bus is described.

[0076] It is understandable that this step is to send the first CAN communication message data generated by the simulation software to the vehicle air conditioning application. Once the air conditioning application receives these CAN communication message data, it will perform corresponding operations according to the instructions and parameters therein, such as adjusting the air conditioning temperature, wind speed or other functions. The results of these operations will be displayed to the user through the application interface or the vehicle's internal display screen, ensuring that the user can understand and control the status and function of the vehicle air conditioning system in real time. For example, the temperature previously adjusted to 20 degrees will be displayed on the display screen.

[0077] As an example, after sending the CAN communication message data to the air-conditioning application, it also includes: obtaining the display page of the corresponding operation information; obtaining the first verification result according to the consistency between the operation information and the display page; if the first verification result is inconsistent, sending a first alarm message to the terminal loaded with the software simulation tool of the vehicle air-conditioning controller; if the first verification result is consistent, requesting the terminal loaded with the air-conditioning application to obtain the second CAN communication message data of the air-conditioning application. Among them, the first verification result refers to the result of the operation information display page received from the air-conditioning application after comparing the CAN communication message data sent to the air-conditioning application by the simulation software. If the display page is inconsistent with the previous operation information, this will cause the first verification result to be inconsistent. For example, if the displayed air-conditioning temperature is 15 degrees, not 20 degrees adjusted in the software simulation tool, the first verification result is inconsistent. The first alarm message refers to the warning or error message sent by the simulation software to the terminal loaded with the vehicle air-conditioning controller software simulation tool when the first verification result is inconsistent, to prompt the developer of possible problems or errors. The second CAN communication message data refers to another set of CAN communication message data that the simulation software requests from the terminal loaded with the air-conditioning application when the first verification result is consistent, which is used for further testing and verification of the function and response of the vehicle air-conditioning application.

[0078] Specifically, this step describes the subsequent operation process after the simulation software simulates sending CAN communication message data to the air-conditioning application. First, the simulation software obtains the operation information page displayed by the air-conditioning application, which reflects the current status of the air-conditioning function and the operations that the user can perform. Then, the simulation software compares the obtained operation information with the expected operation information to verify the accuracy of the simulation result, which is the so-called first verification result. If the first verification result shows that the operation information is inconsistent with the display page, the simulation software will send a first alarm message to the terminal of the software simulation tool loaded with the vehicle air-conditioning controller to remind the developer of possible problems. On the contrary, if the first verification result is consistent, the simulation software will request the terminal loaded with the air-conditioning application to obtain a second set of CAN communication message data to further verify and test the response and function of the air-conditioning application. These steps ensure that the simulation software can effectively simulate and verify the various operations and functions of the vehicle air-conditioning system.

[0079] As an example, after requesting the terminal loaded with the air-conditioning application to obtain the second CAN communication message data of the air-conditioning application, it also includes: obtaining the second CAN communication message data sent by the air-conditioning application, wherein the second CAN communication message data is the corresponding second CAN communication message data generated by the intelligent cockpit controller according to the second operation information of the air-conditioning application, and the intelligent cockpit controller sends the generated second CAN communication message data to the CAN communication device, and the second CAN communication message data is sent by the CAN communication device; the second CAN communication message data is parsed according to the communication matrix information to generate the corresponding second CAN signal simulation data; and the second CAN signal simulation data is displayed accordingly. The second CAN communication message data refers to the CAN communication data generated by the intelligent cockpit controller according to the second operation information of the air-conditioning application, and these data will be sent to the CAN communication device and transmitted through it. The second operation information refers to the instructions or requirements generated by the user or system operation in the air-conditioning application, such as adjusting the air-conditioning temperature, wind speed and other operations. In this embodiment, take the opening of the internal circulation as an example. The second CAN signal simulation data refers to the data parsed from the second CAN communication message data, and the simulation signal data generated after parsing according to the communication matrix information is used to display the state or response of the air-conditioning system in the simulation software.

[0080] Specifically, this step describes the operation flow of the simulation software after obtaining the second CAN communication message data sent by the air-conditioning application. First, the intelligent cockpit controller generates corresponding second CAN communication message data according to the second operation information of the air-conditioning application, and these data are sent to the CAN communication device and transmitted through it. After receiving these second CAN communication message data, the simulation software parses them according to the pre-defined communication matrix information and converts them into corresponding second CAN signal simulation data. Finally, the simulation software uses these second CAN signal simulation data to display them accordingly on the interface to present the status or response of the air-conditioning system in the simulation environment. These steps ensure that the simulation software can effectively simulate and verify the functions and responses of the air-conditioning application.

[0081] As an example, after the corresponding display is performed according to the second CAN signal simulation data, it also includes: obtaining a second verification result according to the consistency between the display page of the second CAN signal simulation data and the second operation information; if the second verification result is inconsistent, sending a second alarm message to the terminal of the software simulation tool for the vehicle air-conditioning controller; if the second verification result is consistent, sending a pass signal to the terminal of the software simulation tool for the vehicle air-conditioning controller. Among them, the second verification result refers to the conclusion drawn by the simulation software after comparing the display page with the second operation information, which is used to verify the accuracy and consistency of the simulation. The second alarm message refers to a warning or notification sent to the terminal of the vehicle air-conditioning controller software simulation tool when the second verification result is inconsistent, to prompt the developer that there is a problem or error. The pass signal refers to a confirmation signal sent to the terminal of the vehicle air-conditioning controller software simulation tool when the second verification result is consistent, indicating that the operation of the simulation is consistent with the expected function and the verification is successful. For example, if the internal circulation is turned on in the air-conditioning application, but the internal circulation is not turned on in the vehicle air-conditioning controller software simulation tool, a warning is issued to prompt the developer that there is a problem.

[0082] Specifically, these steps describe the process of verifying the simulated data of the second CAN signal generated by simulation in the vehicle air conditioning controller software simulation system. First, by comparing the consistency of the display page with the second operation information, a second verification result is obtained to confirm the accuracy of the simulation and the consistency of the expected function. If the second verification result shows inconsistency, it means that there is a functional or operational problem. The system will send a second alarm message to the terminal loaded with the vehicle air conditioning controller software simulation tool, prompting the developer to check and fix the problem. Conversely, if the second verification result is consistent, the system will send a pass signal to the terminal to confirm the correctness of the simulation operation and the successful completion of the verification.

[0083] This embodiment provides a software simulation method for a vehicle air-conditioning controller. The application first obtains operation information from the test interface generated by the simulation, and can provide necessary input data for subsequent simulation operations. These data represent specific instructions or operations of the user interacting with the vehicle air-conditioning controller. Then, according to the obtained operation information, corresponding CAN signal data that can simulate the actual operation of the vehicle air-conditioning controller is generated to provide simulation support for data exchange during the communication process. Then, these CAN signal simulation data are parsed and converted into corresponding CAN communication message data to ensure that the data format and content are consistent with the real CAN communication. Finally, the generated CAN communication message data is sent to the air-conditioning application, so that the air-conditioning remote control displays the corresponding operation information based on these data, thereby realizing the verification and testing of the air-conditioning application function. The entire process performs effective functional verification tests on the air-conditioning application without relying on actual hardware, thereby improving development efficiency.

[0084] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , Figure 2 This is a flow chart of a second embodiment of the software simulation method for a vehicle air conditioning controller of the present application. Step S20 of the software simulation method for a vehicle air conditioning controller includes steps S21 to S22:

[0085] Step S21, obtaining communication matrix information;

[0086] It is understandable that the communication matrix information describing the internal communication rules and protocols of the vehicle system is obtained. This information guides the simulation software on how to accurately simulate the CAN bus communication behavior of the vehicle system, ensuring that the generated simulation data is consistent with the communication protocol of the actual system, so as to effectively carry out system development, joint debugging and commissioning.

[0087] Step S22: parsing the first CAN signal simulation data according to the communication matrix information to generate corresponding first CAN communication message data.

[0088] It is understandable that the first CAN signal simulation data generated by the simulation software is parsed using the pre-acquired communication matrix information. Through this step, the simulation software can accurately convert the simulation data into actual CAN communication message data that meets the requirements of the CAN bus protocol. These generated CAN communication message data will be sent to the air conditioning application to trigger and display the corresponding air conditioning function operation, thereby achieving accurate simulation and function verification of the vehicle system.

[0089] In this embodiment, first, the communication matrix information describing the internal communication rules and protocols of the vehicle system is obtained, and the communication matrix information includes detailed specifications such as the ID, data frame structure, and sending cycle of each CAN communication message; then, the first CAN signal simulation data generated by the simulation software is parsed using the acquired communication matrix information, and during the parsing process, the simulation data is converted into CAN communication message data that conforms to the communication matrix definition; finally, the first CAN communication message data is generated, and the data includes the correct CAN message ID, data content, and sending cycle. These data will be transmitted to the air conditioning application, so that it can perform corresponding operations according to the received information, such as adjusting the air conditioning temperature, wind speed, and other functions, thereby realizing accurate simulation and verification of the vehicle system functions.

[0090] In addition, to achieve the above objectives, the present application also proposes a software simulation system for a vehicle air-conditioning controller, the system comprising a simulated vehicle air-conditioning controller as described above, a terminal loaded with an air-conditioning application, an intelligent cockpit controller and a CAN communication device.

[0091] Please refer to Figure 3 , Figure 3This is a structural diagram of a software simulation system for a vehicle air-conditioning controller for this application, wherein the simulated vehicle air-conditioning controller refers to a software tool for simulating, controlling and testing the functions of a vehicle air-conditioning system. This tool usually allows users to input instructions or parameters through a simulation interface or an operation interface to simulate the operation under different conditions, and can generate corresponding signal data for testing and verifying the various functions, performance and stability of the vehicle air-conditioning system. A CAN communication device refers to a communication device or module of a controller area network (CAN) for data communication between various electronic control units (ECUs) inside a vehicle. These devices are responsible for processing and managing communications on the CAN bus, including sending and receiving CAN messages, ensuring information exchange and coordination between vehicle electronic systems. In vehicles, CAN communication devices play a key role, supporting various real-time control and monitoring functions, such as engine control, braking system, vehicle entertainment, etc. An intelligent cockpit controller refers to an electronic control unit (ECU) inside a vehicle, which is mainly responsible for managing and controlling multiple functions and systems in the vehicle, such as vehicle air-conditioning systems, seat controls, lighting systems, etc. It monitors and adjusts the in-vehicle environment through communication with other ECUs and sensors to improve ride comfort and safety. In modern vehicles, the intelligent cockpit controller plays an important role in integrating and coordinating various in-vehicle functions. Air conditioning applications refer to software applications in the vehicle air conditioning system. They run on the vehicle's electronic control unit (ECU) or on-board computer and are responsible for monitoring and controlling the operation of the in-vehicle air conditioning system. These applications can receive data from sensors and other control modules, and then adjust the operating parameters of the air conditioning system, such as temperature, wind speed, wind direction, etc., according to preset algorithms and user settings to provide a comfortable in-vehicle environment.

[0092] The simulated vehicle air conditioning controller obtains the first operation information input by the user, and generates the first CAN signal simulation data accordingly. Then, the first CAN signal simulation data is parsed according to the communication matrix information, the corresponding first CAN communication message data is generated, and it is sent to the CAN communication device. The CAN communication device transmits the data to the intelligent cockpit controller, which receives and parses the CAN communication message data, and then performs the corresponding operation according to the instructions and parameters therein, and finally sends the processed data back to the air conditioning application. The air conditioning application displays the corresponding operation information according to the received first CAN communication message data. The system includes a structure in which the air conditioning application, the intelligent cockpit controller and the CAN communication device communicate in sequence to ensure the correctness and consistency of the data flow. In the whole process, it also includes the connection of the CAN communication device, the import of the communication matrix information, and the acquisition of the first verification result according to the consistency of the operation information and the display page. If the verification results are inconsistent, the system will send a first alarm message; if they are consistent, it will request to obtain the second CAN communication message data of the air conditioning application. Subsequently, the intelligent cockpit controller generates the second CAN communication message data according to the user's operation on the air conditioning application (the second operation information), and sends it to the simulated vehicle air conditioning controller via the CAN communication device. The simulated vehicle air conditioning controller further parses the second CAN communication message data according to the communication matrix information to generate the corresponding second CAN signal simulation data, and then displays the corresponding second CAN signal simulation data. Finally, according to the consistency between the display page of the second CAN signal simulation data and the second operation information, the second verification result is obtained. If they are inconsistent, the second alarm information is sent, and if they are consistent, a pass signal is sent, indicating that the entire system effectively simulates and verifies various operations and functions of the vehicle air conditioning system.
