[0057] The method provided in the embodiment of the present application can be executed by software on a terminal device, which can be, for example, a mobile phone, a tablet computer, a computer, or the like.

[0058] In order to make the technical personnel in this field better understand the present application, the present application is further described in detail below in combination with the drawings and specific implementation methods. The method provided in the present application embodiment is described below by taking the first device as an example.

[0059] Figure 1 A flowchart of a simulation data display method provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0060] S101: Start the first process.

[0061] The first device starts a first process, and the first process is used to run vehicle simulation software. For example, the vehicle simulation software may be GCVdyn software, which may support functions such as vehicle dynamics performance modeling, handling stability working condition simulation, post-processing, and embedded simulation. GCVdyn can realize functions such as the construction of a vehicle dynamics performance evaluation system, target function decomposition, and virtual testing of dynamic characteristics of an assembly system.

[0062] S102: Utilizing the first process and combining the input vehicle simulation variables to perform simulation to obtain vehicle simulation data.

[0063] The first device can use the first process to perform simulation in combination with the input vehicle simulation variables to obtain vehicle simulation data.

[0064] Exemplarily, the vehicle simulation variables may include at least one of vehicle driving control input information, vehicle parameter information, environmental condition information, and vehicle initial state information.

[0065] The vehicle driving control input information may include basic inputs of driver operations such as steering wheel input, throttle input and brake input. The vehicle parameter information may include: the dynamic parameters of the vehicle, such as vehicle mass, tire characteristics and suspension system parameters. Environmental condition information may include, for example, environmental factors such as road conditions (friction coefficient and slope, etc.), wind speed and temperature. The vehicle initial state information may include, for example, kinematic state quantities such as the initial position, speed and acceleration of the vehicle. In addition, the vehicle simulation variables may also include the driving torque and wheel steering angle of the vehicle, etc. Those skilled in the art may set them according to actual needs, and no unnecessary limitations are made here.

[0066] The simulation parameters of the vehicle may include vehicle state information, vehicle tire force information, and vehicle kinematic and dynamic parameter information.

[0067] Vehicle status information may include the vehicle's speed, acceleration, position, and posture (e.g., yaw rate, roll angle), etc. Vehicle tire force information may include longitudinal force, lateral force, and vertical force, etc. Vehicle kinematic and dynamic parameter information may include: the vehicle's wheel angle, speed, and acceleration, etc.

[0068] S103: Start the second process.

[0069] The second device can start a second process, and the second process is used to run Unity3D software. The first process and the second process can communicate through TCP, wherein the Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. It should be noted that before running the Unity3D software, the second process can first build Unity3D, for example, set the rendering pipeline of the project (for example, it can include a built-in rendering pipeline, a universal rendering pipeline, and a high-definition rendering pipeline, etc.), import vehicle models, road scene models, TCP communication plug-ins, and script templates, etc.

[0070] In some possible implementations, the first device can obtain the window handle of the Unity3D software, and embed the Unity3D software into the vehicle simulation software according to the window handle. When the Unity3D software is embedded in the vehicle simulation software, the second process can be started using the vehicle simulation software running in the first process.

[0071] Exemplarily, the first device can open the GCVdyn 3D animation display page, which is a QWidget window used to embed the UI of the Unity3D program. Use the QProcess class to start the executable file of Unity3D in the GCVdyn program. Use the Windows API function FindWindow to obtain the window handle of the Unity3D program. Use the Windows APISetParent function to set the parent window of the window corresponding to the window handle of Unity3D to the 3D animation page QWidget of the GCVdyn program, thereby embedding the UI of the Unity3D program into GCVdyn. Then GCVdyn establishes TCP communication with the Unity3D software as a TCP server. Embedding the Unity3D software into the vehicle simulation software can provide a more comprehensive, realistic and efficient simulation environment, which helps to improve the quality and efficiency of the simulation.

[0072] S104: Send the vehicle simulation data obtained by the first process to the second process, and use the second process to perform 3D display on the vehicle simulation data.

[0073] The first device can send the vehicle simulation data obtained by the first process to the second process, and use the second process to display the vehicle simulation data in 3D. Figure 2 as well as Figure 3 shown. Figure 2 Some vehicle simulation data may be included.

[0074] In some possible implementations, the first device may obtain user operation information on an interface for 3D display on Unity3D software, wherein the operation information is used to indicate the interface (such as Figure 2 The simulated vehicle in the interface shown in the figure is moved or rotated, and then the position or angle of the simulated vehicle in the interface is adjusted according to the operation information (the angle here refers to the angle from which the user observes the vehicle). For example, according to the operation information, the simulated vehicle is moved from Figure 2 Adjust the angle shown in Figure 3 The angle shown is used so that relevant personnel can observe the display interface more intuitively and clearly.

[0075] In some possible implementations, after the vehicle simulation data is displayed in 3D, the first device can obtain the input target vehicle simulation variable, use the first process to simulate in combination with the input target vehicle simulation variable, obtain the target vehicle simulation data, send the target vehicle simulation data obtained by the first process to the second process, and use the second process to update the interface in combination with the target vehicle simulation data. In this way, the 3D display interface can be updated in real time according to the vehicle simulation variable input by the user.

[0076] The first process is started, wherein the first process is used to run the vehicle simulation software, and the first process is used to simulate in combination with the input vehicle simulation variables to obtain vehicle simulation data, and the second process is started, and the second process is used to run the Unity3D software. The first process and the second process communicate via TCP, and the vehicle simulation data obtained by the first process is sent to the second process, and the vehicle simulation data is displayed in 3D using the second process. Since the vehicle simulation data obtained by the vehicle simulation software can be sent to the Unity3D software, and then the Unity3D software displays the vehicle simulation data in 3D, the 3D display will be more intuitive and rich than the digital data or two-dimensional curve display in the prior art, and the visualization effect of the simulation results will be improved, thereby improving the user experience.
