[0043] Step S102, control the vehicle's display screen to display the airflow effect according to the operating state and the vehicle's air conditioner airflow model.
[0044] Exemplarily, in the present disclosure, the air conditioner airflow model is pre-established according to different vehicle models, where the air conditioner airflow model is used to characterize the distribution state of the airflow output by the air conditioner in the vehicle. The air conditioner airflow model can be constructed based on, for example, Mesh grids, point cloud data, and voxel models.
[0045] The display screen in the present disclosure may include but is not limited to: a central control display screen, an instrument panel, an extended display screen, a rear seat entertainment display screen, a door display screen, a head-up display (HUD), etc.
[0046] In some embodiments, the airflow effect can be generated based on the target animation according to the air conditioner airflow model and the operating state, where the airflow effect can be used to display the flow effect of the airflow output by the air conditioner in the vehicle. Then, the display screen can be controlled to display the airflow effect through the target animation. Among them, the target animation can include UV animation, vertex animation, material animation, etc.
[0047] In other embodiments, the rendering data of the air conditioner airflow model can be determined according to the operating state, and the air conditioner airflow model can be rendered based on the rendering technology of the target animation according to the rendering data to generate the airflow effect. Among them, the operating state can include the operating mode, wind force intensity, wind speed, wind direction, etc. The rendering data can include data such as vertex offset, transparency, mesh form, depth offset, and resolution of the air conditioner airflow model.
[0048] In some other embodiments, on the UV animation channel of the air conditioner airflow model, the UV coordinates can be cyclically offset through the UV Offset node to achieve texture scrolling, thereby simulating the fluctuation frequency and intensity of the output airflow of the air conditioner. In this way, the overhead of the vertex shader and the pixel shader can be effectively reduced, high frame rate can be guaranteed, and rendering latency can be reduced.
[0049] In some other embodiments, the air conditioner airflow model can be adjusted according to the operating state, and then the air conditioner airflow model can be rendered based on the target animation to generate an airflow effect.

[0051] In some other embodiments, the target engine can be integrated with the vehicle's HMI (Human Machine Interface Template) to quickly build a multi-screen linked human-machine interface, thereby improving the product iteration efficiency and user experience.
[0052] In summary, the present disclosure first obtains the operating state of the vehicle's air conditioner, and then controls the vehicle's display screen to display the airflow effect according to the operating state and the vehicle's air conditioner airflow model. Among them, the air conditioner airflow model is pre-established according to the vehicle, and the air conditioner airflow model is used to characterize the distribution state of the airflow output by the air conditioner in the vehicle, and the airflow effect is used to display the flow effect of the airflow output by the air conditioner in the vehicle. The present disclosure controls the vehicle's display screen to display the flow state of the airflow output by the air conditioner in the vehicle according to the pre-established air conditioner airflow model in combination with the operating state of the air conditioner, without relying on a large number of particle emissions and complex physical calculations, and can reduce the rendering latency of the airflow effect and ensure a high frame rate of the display screen.

[0054] In some other embodiments, the rendering efficiency of 60 fps can be maintained, and different UV Tilling can be used to simulate the random effects of the airflow output from different air ducts of the air conditioner.
[0055] In some other embodiments, the size of the Alpha value in the PS (Pixel Shader) and the vertex offset in the VS (Vertex Shader) can be dynamically controlled. Among them, the larger the Alpha value, the lower the transparency and the more obvious the cold fog effect, so as to present the airflow effects at different temperatures; the larger the vertex offset value, the greater the amplitude and intensity of the airflow, so as to present the air conditioner intensity at different gears.
[0056] In some other embodiments, the rendering data may include a mesh form. The mesh form of the air conditioner airflow model around the target component can be determined according to the running state and the target depth relationship, where the target depth relationship may include the depth relationship between the air conditioner airflow model and the component model corresponding to the target component of the vehicle, and the target component may be, for example, a steering wheel, a seat, etc.
[0057] In some other embodiments, in the Unity engine, Camera.depthTextureMode can be enabled to output depth textures, and the depth relationship between the air conditioner airflow model and the component model can be judged by reading the Depth Texture. In different running states, according to the depth relationship between the air conditioner airflow model and the component model, by using the technology that when a simulated water body intersects with a solid, the water body shows different transparency levels according to different depths, the airflow output by the air conditioner can be fitted to the surface of the component model to achieve seamless fusion, avoiding the visual conflict between the airflow effect and the target component.
[0058] In some other embodiments, the running state may include the running mode and the wind intensity, and the rendering data may include a mesh form. The mesh form of the air conditioner airflow model can be determined according to the running mode and the wind intensity.
[0059] In some other embodiments, in the Unity engine, a SkinnedMeshRenderer component can be mounted for the air conditioner airflow model, and under the specified running mode or wind intensity, the BlendShape weight can be driven through the SetBlendShapeWeight API to distort the mesh form in real time and strengthen the three-dimensional texture of the wind flow.
[0060] In some other embodiments, an animation curve can be combined with the BlendShape to distort the mesh form of the air conditioner airflow model, so as to present diverse airflow wind effect shapes when the running mode or the wind intensity changes.
[0061] In this way, the expressiveness during the wind effect dragging is achieved through the BlendShape, rather than through a single mesh form, bringing a stronger user interaction experience.
[0062] In some other embodiments, the rendering data may include a depth offset. In the case where the airflows of multiple air ducts of the air conditioner overlap, the depth offset of the overlapping area of the airflows in the air conditioner airflow model can be determined according to the operating state.
[0063] In some other embodiments, in the Unity engine, it is possible to support the parallel rendering of the airflow effects corresponding to multiple air ducts in the same area. The depth offset is set through the Offset command of ShaderLab and coordinated with the RenderQueue sorting to eliminate rendering conflicts and overcome the Z-Fighting problem.
[0064] In some other embodiments, the air conditioner airflow model can be rendered according to the first preset rendering order and the rendering data to obtain an airflow effect.

[0065] In some other embodiments, independent Passes and sub-Shaders can be set for airflow levels with different priorities to ensure a distinct mixing effect of multiple airflow levels.
[0066] In some other embodiments, the rendering data may include a resolution. The resolution can be determined according to the operating state and the projection height ratio, where the projection height ratio is used to represent the ratio of the display size of the air conditioner airflow model to the size of the display screen.
[0067] In some other embodiments, in the Unity engine, the LODGroup component can be used to automatically switch the air conditioner airflow models and UV maps with different resolutions according to the projection height ratio, thereby reducing the vertex and pixel load and ensuring that the rendering latency on a mobile-level GPU (Graphics Processing Unit) is < 30 ms. And the span and transition method can be configured to achieve smooth LOD switching.
[0068] In some other embodiments, the rendering data may include a rendering color. The rendering color of the air conditioner airflow model can be determined according to the operating state, where the depth of the rendering color can represent the intensity of the airflow, and the depth of the rendering color and the intensity of the airflow can be positively correlated. That is to say, the stronger the airflow intensity, the deeper the rendering color.
[0069] In some other embodiments, in the Unity engine, the offset rate of the UV coordinates and the mixing ratio of the double-color gradient map can be controlled through a binary mapping function, and the real-time wind speed value of the air conditioner is continuously mapped into a gradient overlay layer from dark blue to light cyan to intuitively present the strength of the airflow. Among them, the mapping parameters of the binary mapping function can be adjusted online to adapt to different visual needs.
[0070] In some other embodiments, the air-conditioning airflow model may be rendered according to a second preset rendering order and rendering data to obtain an airflow effect. Among them, the second preset rendering order represents the rendering order between the air-conditioning airflow model and other models, and the other models may include models displayed on the display screen except the air-conditioning airflow model, such as a vehicle model, a human body model, etc.
[0071] In some other embodiments, in the Unity engine, a ScriptableRendererFeature may be created in the URP (Universal Render Pipeline), and a custom ScriptableRenderPass may be injected in AddRenderPasses, so as to arrange the rendering order of the airflow effect in the scene more flexibly, so as to adapt to the rendering effect and efficiency of the airflow effect under different software and hardware configurations. And, a CommandBuffer may be used in the RenderPass for dynamic batching to improve the overall rendering efficiency of the airflow effect.
[0072] In some other embodiments, there may be multiple airflow effects. In the case where there are multiple airflow effects, the multiple airflow effects may be superimposed, and the display screen may be controlled to display the superimposed airflow effect.
[0073] In some other embodiments, in the Unity engine, the airflow effects corresponding to the UV animation, color mapping, and depth fusion results may be output by superimposing passes such as blur and color grading in the Unity Post-Processing Stack, so as to unify the visual style of the user interface controls and the airflow animation. In this way, different Post-Process effects can be plugged in according to project requirements to achieve flexible art optimization, making the rendering pre- and post-processing processes easier to maintain and customize.
[0074] In summary, the present disclosure first obtains the operating state of the air conditioner of the vehicle, and then controls the display screen of the vehicle to display the airflow effect according to the operating state and the air-conditioning airflow model of the vehicle. Among them, the air-conditioning airflow model is established in advance according to the vehicle, and the air-conditioning airflow model is used to characterize the distribution state of the airflow output by the air conditioner in the vehicle, and the airflow effect is used to display the flow effect of the airflow output by the air conditioner in the vehicle.

[0106] Those skilled in the art can also understand that the various illustrative logical blocks and steps listed in the embodiments of the present application can be implemented by electronic hardware, computer software, or a combination of both. Whether such a function is implemented by hardware or software depends on the specific application and the design requirements of the entire system. Those skilled in the art can use various methods to implement the described functions for each specific application, but such implementation should not be construed as exceeding the scope protected by the embodiments of the present application.
[0107] In addition, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be understood as being advantageous as compared to other aspects or designs. Instead, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to mean any arrangement in a natural inclusive permutation. That is, if X applies A; X applies B; or X applies both A and B, then "X applies A or B" is satisfied in any of the foregoing instances. Additionally, unless otherwise specified or clear from the context indicating a singular form, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more".
[0108] Similarly, although the present disclosure has been shown and described with respect to one or more implementations, those skilled in the art will envision equivalent variations and modifications after reading and understanding this specification and the drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. Specifically with respect to the various functions performed by the components (e.g., elements, resources, etc.) described above, unless otherwise indicated, the terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if not structurally equivalent to the disclosed structure. Additionally, although a particular feature of the present disclosure may have been disclosed with respect to only one of several implementations, such a feature may be combined with one or more other features of other implementations as may be desired and advantageous for any given or particular application. Furthermore, with respect to the use of "comprising", "possessing", "having", "include", or variations thereof in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term "including".
[0109] Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include known common knowledge or conventional technical means in the technical field not disclosed herein. The specification and examples are only illustrative, and the true scope and spirit of the present disclosure are pointed out by the appended claims.
[0110] It should be understood that the present disclosure is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present disclosure is only limited by the appended claims.
[0111] It should be understood that, unless otherwise specifically stated, the features of some embodiments of the present disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of any two or more of them; similarly, "at least one of......" includes any one of the related listed items and any combination of any two or more of them.
[0112] Although terms such as "first", "second", and "third" may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Instead, these terms are only used to distinguish one component, part, region, layer, or section from another. Thus, the first component, part, region, layer, or section mentioned in the examples described herein can also be referred to as the second component, part, region, layer, or section without departing from the teachings of the respective examples. Additionally, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description herein, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.
[0113] It should be understood that, as used herein, spatial relative terms, such as "above", "upper", "below", and "lower", are used to describe the relationship of one element shown in the figures to another element. In addition to the orientation depicted in the figures, such spatial relative terms are also intended to encompass different orientations of the device during use or operation. For example, if the device in the figures is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to that other element. Thus, depending on the spatial orientation of the device, the term "above" encompasses both the above and below orientations. The device may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.
