[0061] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0063] As described in the background section, the relevant data simulation technology is still insufficient to meet the needs of practical work.

[0064] In the process of developing this application, the applicant discovered that, in related simulation technologies, although current simulation analysis equipment can solve virtual models, it is often used for offline simulation because it is not connected to actual hardware.

[0065] In other words, current simulation analysis equipment often uses historical data or summarized data as operating condition data and uses this operating condition data for simulation. However, since it cannot connect to actual hardware during simulation, it cannot form real-time data interaction with the actual hardware. As a result, it is difficult to use real-time data from the actual hardware in the simulation environment or real operating conditions for simulation. Consequently, the simulation results of the simulation analysis equipment are often not ideal and cannot meet the testing requirements of the actual hardware in actual operating conditions.

[0066] In addition, hardware-in-the-loop (HIL) simulation technology is also used in data simulation work. HIL is a simulation testing method that combines actual hardware with virtual models. However, in HIL, it is still difficult to solve complex virtual models because there is currently no HIL device developed for complex virtual models.

[0067] To address the problems in the prior art, embodiments of this application provide a method, apparatus, and electronic device for data simulation. By combining a hardware-in-the-loop (HIL) simulation device with a simulation analysis device, and through their interaction, the HIL simulation device sends real-time operating condition data of the actual hardware to the simulation analysis device. This enables the simulation analysis device to acquire the real-time operating condition data and perform data simulation, thereby obtaining simulation results that match the actual operating conditions.

[0068] The data simulation method provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0069] Figure 1 This illustration shows an application scenario of the data simulation method provided in one embodiment of this application.

[0070] exist Figure 1 The scenarios shown include: simulation analysis equipment, hardware-in-the-loop simulation equipment, and actual hardware.

[0071] The simulation analysis equipment includes a background service unit and a real-time analysis unit, with the real-time analysis unit including a processor.

[0072] Furthermore, the hardware-in-the-loop simulation device includes a hardware-in-the-loop simulation model, and the hardware-in-the-loop simulation model includes a co-simulation interface.

[0073] Furthermore, the actual hardware is the hardware to be tested.

[0074] Among them, the hardware-in-the-loop simulation model is a model that matches the actual hardware and is used to control the actual hardware or be controlled by the actual hardware.

[0075] In some specific examples, the actual hardware can be, for example, the suspension system of a vehicle, and the hardware-in-the-loop model can be, for example, a virtual model of simulated electronic components. The actual hardware of these electronic components can be electrically connected to the suspension system to enable the interaction of operating condition data with the suspension system, so as to control the suspension system or be controlled by the suspension system.

[0076] In this embodiment, the simulation analysis device may be, for example, an electronic device for running simulation analysis programs, which has an information interaction port to enable information interaction with other electronic devices.

[0077] The simulation analysis program can be, for example, a simulation analysis program used to perform kinematic and / or dynamic simulation analysis on mechanical and / or electromechanical systems. Through the simulation analysis program, complex virtual models can be built, and the complex virtual models can be solved using local data from the simulation analysis equipment.

[0078] Furthermore, the hardware-in-the-loop simulation device can be, for example, an electronic device used to run a hardware-in-the-loop simulation program. This electronic device also has an information interaction port to enable information interaction with other electronic devices and can establish an electrical connection with actual hardware, thereby enabling the interaction of operating condition data with the actual hardware.

[0079] Based on this, Figure 1 As shown, the co-simulation interface of the hardware-in-the-loop simulation device can interact with the actual hardware, and the co-simulation interface can also establish electrical and / or communication connections with the background service unit and real-time analysis unit of the simulation analysis device, thereby enabling the background service unit and real-time analysis unit of the simulation analysis device to interact with the co-simulation interface respectively.

[0080] Furthermore, Figure 2 The interactive scenario between the hardware-in-the-loop simulation device and the simulation analysis device is shown.

[0081] like Figure 2 As shown, a host computer and a switch are also set up between the hardware-in-the-loop simulation equipment and the simulation analysis equipment.

[0082] The host computer can be, for example, a monitoring device, used to monitor hardware-in-the-loop simulation equipment and simulation analysis equipment.

[0083] Furthermore, switches are used to transmit information and operating condition data between hardware-in-the-loop simulation equipment and simulation analysis equipment.

[0084] Specifically, when hardware-in-the-loop simulation equipment communicates and interacts with simulation analysis equipment, a communication network can be established through a switch to complete the interaction of information and data. For example, a communication network using the UDP protocol (User Datagram Protocol) can be established, and the interaction of information and data can be completed through the UDP protocol network. Specifically, the information and data exchanged between the hardware-in-the-loop simulation equipment and the simulation analysis equipment can be transmitted in the form of UDP packets.

[0085] It can be seen that, based on the above Figure 1 Application scenarios and Figure 2 The interactive scenario enables the exchange of information and operating condition data between the hardware-in-the-loop simulation equipment and the simulation analysis equipment.

[0086] In another embodiment of this application, based on Figure 1 and Figure 2 The application scenarios and interaction scenarios shown are as follows: Figure 3 The specific execution steps of the data simulation method are shown.

[0087] like Figure 3 As shown, when performing data simulation on actual hardware, based on the communication interaction established in the aforementioned embodiment, the hardware-in-the-loop simulation device executes S301: sending the start command and the file information of the simulation model file of the threshold to the simulation analysis device.

[0088] Specifically, when the hardware-in-the-loop simulation device begins simulating the actual hardware, as in the aforementioned embodiments... Figure 2 As shown, based on the configured co-simulation interface, the hardware-in-the-loop simulation device can use the co-simulation interface to send start commands and simulation model file information to the simulation analysis device.

[0089] In some specific examples, file information may include, for example, the address of the simulation analysis device, the simulation model file, the processor configuration parameters, and the running parameters of the simulation model file.

[0090] The simulation model file is a specific virtual model for the simulation analysis program running in the simulation analysis device. Different simulation model files are set for different actual hardware. Each simulation model file can be stored in the hardware-in-the-loop simulation device in advance. When the hardware-in-the-loop simulation device performs data simulation on the actual hardware, the hardware-in-the-loop simulation device retrieves the corresponding simulation model file and sends the simulation model file to the simulation analysis device.

[0091] Furthermore, the running parameters of the simulation model file are used by the simulation analysis equipment to control the simulation analysis program to run the simulation model file. For example, the running parameters can be parameters such as the operation step size of the simulation operation, and are used to control the simulation model file to run with the set operation step size and other parameters when running data simulation. The running parameters can also be, for example, whether to enable simulation animation.

[0092] Furthermore, the processor configuration parameters are used by the simulation analysis device to configure the processor in the real-time analysis unit. For example, when the simulation analysis program runs the simulation model file, the simulation analysis device configures the processor running the simulation analysis program according to the configuration parameters, thereby seizing more computing resources for data simulation.

[0093] Specifically, the simulation analysis device can preempt real-time processor cores, for example, preempting 4 cores in a 7-core processor to run the simulation analysis program. The simulation analysis device can also configure the simulation analysis program process as a real-time scheduling process. The simulation analysis device can also configure the simulation analysis program process as a high priority, thereby enabling the simulation analysis program process to respond faster and preempt low-priority computing resources, thus ensuring the real-time performance of the data simulation process during runtime, reducing latency during real-time data simulation and improving stability.

[0094] Furthermore, the simulation analysis device can also improve the performance of the simulation analysis program during data simulation by configuring the process of the simulation analysis program to run on a specific processor and isolating other program processes unrelated to data simulation from that specific processor.

[0095] In this embodiment, the hardware-in-the-loop simulation device can use a co-simulation interface to encapsulate the simulation model file, processor configuration parameters, address of the simulation analysis device, and running parameters of the simulation model file.

[0096] Specifically, the co-simulation interface can encapsulate simulation model files, processor configuration parameters, the address of simulation analysis devices, and the runtime parameters of simulation model files into a package such as... Figure 4 In the module shown.

[0097] in, Figure 4 A module interface for encapsulating file information in a hardware-in-the-loop simulation device is shown, in which the information of each file can be set.

[0098] As can be seen in the example of this module interface, the hardware-in-the-loop simulation device can set the address of the simulation analysis device, for example, setting it to 1.3.5.6; the hardware-in-the-loop simulation device can also set the simulation model file to be retrieved, for example, by selecting a button to retrieve the required vehicle suspension model; the hardware-in-the-loop simulation device can also set the running parameters of the simulation model file, for example, setting the calculation step size of the vehicle suspension model to 0.001; the hardware-in-the-loop simulation device can also set whether to enable simulation animation, for example, by checking the box to enable simulation animation; the hardware-in-the-loop simulation device can also set the processor configuration parameters, for example, setting to preempt 4 of the multiple processor cores.

[0099] Based on this, after the hardware-in-the-loop simulation device completes the setting of the aforementioned file information, that is, after the file information is encapsulated, the hardware-in-the-loop simulation device can... Figure 4 Use the settings button in the module interface to save the above file information, and use the apply button to apply the above file information.

[0100] When the application button is clicked, it is assumed that the hardware-in-the-loop simulation device can apply the above file information to the simulation analysis device. Accordingly, the co-simulation interface in the hardware-in-the-loop simulation device will send the processor configuration parameters, the address of the simulation analysis device, and the running parameters of the simulation model file, etc., from the module interface to the simulation analysis device according to the address of the simulation analysis device in the file information, thereby causing the simulation analysis device to start the simulation process.

[0101] In this embodiment, the hardware-in-the-loop simulation device can send both the startup command and file information to the simulation analysis device simultaneously; the hardware-in-the-loop simulation device can also send the startup command first and then the file information; or the hardware-in-the-loop simulation device can send the file information first and then the startup command. The order in which the hardware-in-the-loop simulation device sends the startup command and the file information is not limited here.

[0102] Furthermore, after the hardware-in-the-loop simulation device sends the start command and file information to the simulation analysis device, the simulation analysis device can receive the start command and file information.

[0103] Specifically, based on the background service unit in the aforementioned embodiments, such as Figure 1 As shown, the simulation analysis device uses the background service unit to receive the start command sent by the co-simulation interface, and receives the simulation model file, processor configuration parameters, simulation analysis device address, and simulation model file running parameters from the file information.

[0104] Furthermore, based on the received start command, the simulation analysis equipment can load the simulation model file according to the file information, that is, execute... Figure 3 S302 in the context: Starts the simulation process based on the startup command and loads the simulation model file based on the file information.

[0105] Specifically, based on the background service unit in the aforementioned embodiments, such as Figure 1 As shown, the simulation analysis device can start the simulation process based on the start command received from the background service unit.

[0106] Furthermore, after the simulation analysis device starts the simulation process, it uses the background service unit to send the simulation model file, processor configuration parameters, simulation analysis device address, and simulation model file running parameters from the file information to the real-time analysis unit.

[0107] Furthermore, the real-time analysis unit loads the simulation model file after receiving the file information.

[0108] Specifically, the real-time analysis unit analyzes the processor according to the processor configuration parameters in the file information. Figure 1Configure the processor in it.

[0109] Furthermore, the real-time analysis unit inputs the running parameters of the simulation model file into the simulation model file.

[0110] Furthermore, the real-time analysis unit uses the configured processor to load the simulation model file with the aforementioned operating parameters.

[0111] Accordingly, the simulation analysis equipment can further perform Figure 3 S303 in the code: After loading is completed, send the status information of loading completion to the hardware-in-the-loop simulation device.

[0112] Specifically, after the real-time analysis unit completes the loading of the simulation model file, the real-time analysis unit generates corresponding status information based on the loading completion status, such as... Figure 1 As shown, the real-time analysis unit sends the status information to the background processing unit.

[0113] Furthermore, such as Figure 1 As shown, the background processing unit sends this status information to the co-simulation interface in the hardware-in-the-loop simulation device.

[0114] Furthermore, upon receiving this status information, the co-simulation interface in the hardware-in-the-loop simulation device considers that the simulation analysis device is ready to perform data simulation.

[0115] In this embodiment, the hardware-in-the-loop simulation device and the simulation analysis device can perform data simulations over multiple simulation cycles to simulate the actual hardware, thereby obtaining more accurate and reliable simulation results.

[0116] Accordingly, after receiving the status information sent by the simulation analysis device, the hardware-in-the-loop simulation device can start the simulation cycle and further execute... Figure 3 S304 in the middle sends real-time operating condition data to the simulation analysis equipment.

[0117] Specifically, in each simulation cycle, according to the aforementioned embodiments, the hardware-in-the-loop simulation device can perform real-time hardware-in-the-loop simulation of the actual hardware through the hardware-in-the-loop simulation model, thereby obtaining real-time operating condition data from the hardware-in-the-loop simulation model.

[0118] Based on this, the hardware-in-the-loop simulation model in the hardware-in-the-loop simulation equipment can use the co-simulation interface to send the obtained real-time operating condition data to the simulation analysis equipment, and specifically, it can directly send the real-time operating condition data of the current simulation cycle to the real-time analysis unit in the simulation sub-equipment.

[0119] Accordingly, the simulation analysis equipment can further perform Figure 3S305 in the model: Input real-time operating condition data into the simulation model file and run it to obtain output data through data simulation based on real-time operating condition data.

[0120] Specifically, in each simulation cycle, the real-time analysis unit in the simulation analysis device can directly receive real-time operating condition data sent by the co-simulation interface. Based on the aforementioned loaded simulation model file, the real-time analysis unit can input the real-time operating condition data into the simulation model file.

[0121] Accordingly, the real-time analysis unit can use the processor configured according to the aforementioned configuration parameters to run the simulation model file based on real-time operating data and set according to the aforementioned operating parameters, in order to perform data simulation for the current simulation cycle.

[0122] Furthermore, after the real-time analysis unit completes the data simulation for the current simulation cycle, the output data for the current simulation cycle can be obtained.

[0123] Accordingly, the simulation analysis equipment can further perform Figure 3 S306 in the code: Send output data to the hardware-in-the-loop simulation device.

[0124] Specifically, after the real-time analysis unit obtains the output data for the current simulation cycle, it can directly send the output data to the co-simulation interface in the hardware-in-the-loop simulation device.

[0125] Accordingly, after receiving the output data sent by the real-time analysis unit, the hardware-in-the-loop simulation device can further execute... Figure 3 S307 in the example: Update real-time operating condition data using output data.

[0126] Specifically, after receiving the output data of the current simulation cycle sent by the real-time analysis unit, the co-simulation interface in the hardware-in-the-loop simulation equipment updates the real-time operating data of the current simulation cycle using the output data of the current simulation cycle, and obtains the real-time operating data of the next simulation cycle.

[0127] In some embodiments, the hardware-in-the-loop simulation model can use the output data of the current cycle to calculate the real-time operating data of the next simulation cycle; the hardware-in-the-loop simulation model can also use the output data to interact with the connected actual hardware to obtain the real-time operating data of the next simulation cycle.

[0128] Therefore, the hardware-in-the-loop simulation equipment can further perform... Figure 3 S308 in the figure: sends updated real-time operating condition data to the simulation analysis equipment, thereby enabling the hardware-in-the-loop simulation equipment to complete the data simulation of the current simulation cycle.

[0129] Furthermore, after receiving the updated real-time operating conditions sent by the hardware-in-the-loop simulation device, the real-time analysis unit in the simulation analysis device can perform data simulation for the next simulation cycle.

[0130] In this embodiment, the hardware-in-the-loop simulation device will detect in real time whether a preset termination time has been reached. The termination time can be, for example, a preset duration, a preset moment, or a preset number of simulation cycles.

[0131] Therefore, when the hardware-in-the-loop simulation device detects that the termination time has been reached, that is, when the hardware-in-the-loop simulation device executes... Figure 3 S309 in the code: If the preset termination time is detected, the hardware-in-the-loop simulation device can proceed to further execution. Figure 3 S310 in the middle: Sends a termination command to the simulation analysis device.

[0132] Specifically, when the hardware-in-the-loop simulation device sends a termination command, the co-simulation interface can be used to send the termination command to the simulation analysis device.

[0133] Furthermore, after receiving the termination command sent by the co-simulation interface, the background service unit in the simulation analysis equipment can execute... Figure 3 S311 in the code: End the simulation process.

[0134] Specifically, when the background service unit executes the termination command, it can directly shut down the simulation process of the data simulation currently running in the real-time analysis unit.

[0135] Furthermore, the background service unit releases the resources used when running the simulation model file.
