Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a method for generating dynamic wallpapers for vehicles, a control device, a vehicle, a medium, and a product. Background Technology

[0002] As automotive intelligence continues to advance, the user experience of in-vehicle infotainment systems, as a crucial interface for human-computer interaction, is receiving increasing attention. In-vehicle wallpapers, as an important component of these systems, not only beautify the interface but also serve as a vital medium for reflecting the vehicle's level of intelligence and users' personalized needs. Traditional in-vehicle wallpapers are mostly static images, lacking dynamic changes and interactivity, failing to provide users with a rich visual experience. Therefore, some vehicles have adopted dynamic wallpaper solutions; however, existing dynamic wallpapers typically use preset animation effects or simple image carousels, resulting in relatively limited dynamic changes. Summary of the Invention

[0003] This application provides a method, control device, vehicle, medium, and product for generating live wallpapers for in-vehicle systems, aiming to solve the problem that live wallpapers for in-vehicle systems in the prior art have relatively monotonous changes.

[0004] In a first aspect, this application provides a method for generating dynamic wallpapers for in-vehicle systems, comprising: determining the phenological information corresponding to each pentad in the lunar year; wherein the lunar year includes 24 solar terms, and each solar term includes 3 pentads; based on the phenological information of a first target pentad and a second target pentad in each pentad, interpolating the phenological information of each time node in the first target pentad to obtain a phenological information time sequence of the first target pentad; wherein the first target pentad and the second target pentad are adjacent pentads; generating a phenological knowledge database based on the phenological information time sequence of the first target pentad; and generating a dynamic wallpaper for the in-vehicle system that changes with time nodes based on the phenological knowledge database.

[0005] The in-vehicle dynamic wallpaper generation method provided in this application divides the lunar year into 24 solar terms and 72 pentads, accurately capturing the changing patterns of nature. By interpolating the phenological information of adjacent pentads, the continuity and smooth transition of phenological information are achieved, avoiding abrupt changes in the wallpaper. A phenological knowledge database is constructed, providing a rich data foundation for dynamic wallpaper generation. The final generated in-vehicle dynamic wallpaper changes naturally with time, reflecting the profound connotations of traditional culture and providing a smooth visual experience, effectively enhancing the user experience and cultural identity.

[0006] In some possible implementations, generating a phenological knowledge database based on the phenological information time series of a first target phenological ...

[0007] According to the above embodiments, by converting the phenological information time series into a first target time series containing visual element information, a mapping from abstract phenological information to specific visual elements is achieved, providing direct visual guidance for wallpaper generation. By determining the corresponding target information for each time node, it is ensured that the dynamic wallpaper has corresponding visual performance at different time points, guaranteeing the continuity and integrity of wallpaper changes. The phenological knowledge database generated based on the first target time series has a clear structure and rich data, providing an efficient data retrieval and matching foundation for subsequent wallpaper generation.

[0008] In some possible implementations, the target information includes phenological information for the target time point and corresponding visual element information for each wallpaper style in at least one wallpaper style.

[0009] According to the above embodiments, by providing visual element information under multiple wallpaper styles for phenological information at each time point, the diversification and personalization of wallpaper styles are achieved. Users can choose different wallpaper styles according to their personal preferences, such as realistic style, ink painting style, cartoon style, etc., to meet the aesthetic needs of different users. At the same time, the visual element information of multiple styles also provides the vehicle system with the possibility of automatically adapting the wallpaper style according to factors such as vehicle brand characteristics and interior style, further enhancing the personalization of the user experience.

[0010] In some possible implementations, the target information includes visual element information and agricultural culture information under the solar term of the target time node; wherein, agricultural culture information includes at least one of the following: agricultural activities, traditional customs, health preservation concepts, and poems and songs.

[0011] According to the above embodiments, by integrating agricultural cultural information into the target information, the generated dynamic wallpaper for in-vehicle systems not only possesses visual appeal but also carries rich cultural connotations. Information on agricultural activities allows users to understand agricultural production activities at the current time of year, enhancing their awareness of natural rhythms. Information on traditional customs helps to inherit and promote excellent traditional Chinese culture. Information on health preservation concepts provides users with guidance for a healthy lifestyle. Information on poetry and songs enhances the artistry and cultural taste of the wallpaper. This multi-dimensional integration of cultural information makes in-vehicle wallpapers an important carrier for disseminating traditional culture, effectively enhancing users' cultural experience and sense of belonging.

[0012] In some possible implementations, the phenological information corresponding to each phenological period is the phenological information corresponding to each phenological period in the target region; wherein, the target region is each of at least one region.

[0013] According to the above embodiments, by determining corresponding phenological information for different regions, the vastness of the territory and the diversity of climates are fully considered, ensuring the accuracy and regional adaptability of the phenological information. Users can select the corresponding phenological information according to their location or regions of interest, making the generated dynamic wallpapers more in line with the local natural environment and cultural characteristics. This localized phenological information processing not only enhances the authenticity and credibility of the wallpapers, but also provides convenience for cross-regional travel or learning about different regional cultures, enhancing the practicality and educational value of the in-vehicle infotainment system.

[0014] In some possible implementations, visual element information includes: image elements representing phenological phenomena, color elements, and atmosphere elements.

[0015] According to the above embodiments, by subdividing visual element information into image elements, color elements, and atmosphere elements, a comprehensive visual expression of phenological phenomena is achieved. Image elements can intuitively display specific phenological phenomena, such as plant flowering and animal activity. Color elements, through changes in parameters such as hue, saturation, and brightness, reflect the gradual changes of seasons and time. Atmosphere elements create corresponding environmental atmospheres through lighting effects and weather conditions. The organic combination of these three elements makes the generated dynamic wallpaper both visually impactful and maintains a depth of cultural connotation, providing users with an immersive visual experience.

[0016] In some possible implementations, generating a dynamic in-vehicle wallpaper that changes with time nodes based on a phenological knowledge database includes: determining a wallpaper style; wherein the wallpaper style is selected by the vehicle occupants or determined based on the wallpaper styles of the in-vehicle system's historical wallpapers; determining target visual element information corresponding to each of the current time node and multiple subsequent time nodes based on the wallpaper style and visual element information corresponding to each of the current time node and multiple subsequent time nodes in the phenological knowledge database; determining wallpaper prompt words corresponding to each of the current time node and multiple subsequent time nodes based on the target visual element information; generating static wallpapers corresponding to each of the current time node and multiple subsequent time nodes based on the wallpaper prompt words; and performing transition rendering on the static wallpapers to obtain the dynamic in-vehicle wallpaper.

[0017] According to the above embodiments, by supporting users to independently select wallpaper styles or automatically determining styles based on historical preferences, personalized and intelligent wallpaper generation is achieved. By determining the target visual element information at the current and multiple subsequent time points, a data foundation is provided for continuous wallpaper changes, avoiding abrupt wallpaper transitions. By converting visual element information into wallpaper prompts, a standardized conversion from data to generation instructions is achieved, facilitating subsequent wallpaper generation processing. By generating static wallpapers first and then performing transition rendering, the quality of the wallpaper at each time point is ensured, and smooth transitions between wallpapers are achieved. The final generated dynamic wallpaper has a smooth visual effect and rich cultural connotations, enhancing the user experience.

[0018] Secondly, this application provides a control device, comprising: a determining module for determining phenological information corresponding to each pentad in the lunar year; wherein the lunar year includes 24 solar terms, and each solar term includes 3 pentads; a processing module for interpolating phenological information at each time node of the first target pentad based on the phenological information of the first target pentad and the second target pentad in each pentad, to obtain a phenological information time sequence of the first target pentad; wherein the first target pentad and the second target pentad are adjacent pentads; a constructing module for generating a phenological knowledge database based on the phenological information time sequence of the first target pentad; and a wallpaper generating module for generating a dynamic in-vehicle wallpaper that changes with time nodes based on the phenological knowledge database.

[0020] In some embodiments, the target information includes the visual element information corresponding to the phenological information of the target time point under each wallpaper style in at least one wallpaper style.

[0021] In some embodiments, the target information includes visual element information and agricultural culture information under the solar term of the target time node; wherein, agricultural culture information includes at least one of the following: agricultural activities, traditional customs, health preservation concepts, and poems and songs.

[0022] In some embodiments, the phenological information corresponding to each phenological period is the phenological information corresponding to each phenological period in the target region; wherein, the target region is each of at least one region.

[0023] In some embodiments, visual element information includes: image elements representing phenological phenomena, color elements, and atmosphere elements.

[0024] In some embodiments, the wallpaper generation module is specifically used to determine the wallpaper style; wherein the wallpaper style is selected by the vehicle occupants, or determined based on the wallpaper style of the vehicle's historical wallpapers; based on the wallpaper style and the visual element information corresponding to the current time node and multiple subsequent time nodes in the phenological knowledge database, the module determines the target visual element information corresponding to the current time node and multiple subsequent time nodes; based on the target visual element information, the module determines the wallpaper prompt words corresponding to the current time node and multiple subsequent time nodes; based on the wallpaper prompt words, the module generates static wallpapers corresponding to the current time node and multiple subsequent time nodes; and performs transition rendering on the static wallpapers to obtain the vehicle's dynamic wallpaper.

[0035] As automotive intelligence continues to advance, the user experience of in-vehicle infotainment systems, as a crucial interface for human-computer interaction, is receiving increasing attention. In-vehicle wallpapers, as an important component of these systems, not only beautify the interface but also serve as a vital medium for reflecting the vehicle's level of intelligence and users' personalized needs. Traditional in-vehicle wallpapers are mostly static images, lacking dynamic changes and interactivity, failing to provide users with a rich visual experience. Therefore, some vehicles have adopted dynamic wallpaper solutions; however, existing dynamic wallpapers typically use preset animation effects or simple image carousels, resulting in relatively limited dynamic changes.

[0036] Meanwhile, with the rise of the "Guochao" (national trend) culture, some car manufacturers have begun to incorporate elements of traditional Chinese festivals into their in-car infotainment systems. For example, on the days of the Spring Festival and Mid-Autumn Festival, the system automatically switches the wallpaper to a pre-made festival-themed image or marks the lunar calendar date in the calendar application. However, such solutions only achieve event triggering based on a single date and do not involve in-depth utilization of the cultural resource of solar terms, which have an inherent temporal progression structure.

[0037] To address the aforementioned technical issues, this application provides a method for generating dynamic wallpapers for in-vehicle systems. This method divides the lunar year into 24 solar terms and 72 pentads, accurately capturing the changing patterns of nature. By interpolating the phenological information of adjacent pentads, it achieves continuity and smooth transitions in phenological information, avoiding abrupt changes in the wallpaper. A phenological knowledge database is constructed, providing a rich data foundation for dynamic wallpaper generation. The resulting dynamic wallpaper changes naturally with time, reflecting the profound connotations of traditional culture and providing a smooth visual experience, effectively enhancing the user experience and cultural identity.

[0038] The in-vehicle dynamic wallpaper generation system provided in this application will be described in detail below with reference to the accompanying drawings.

[0039] The in-vehicle dynamic wallpaper generation system provided in this application embodiment can be applied to electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), fuel cell vehicles (FCVs), etc. Please refer to... Figure 1The in-vehicle dynamic wallpaper generation system includes an in-vehicle terminal 10 and a cloud terminal 20, which are connected via communication. The in-vehicle terminal 10 is responsible for determining the phenological information corresponding to each pentad in the lunar calendar, and for interpolating the phenological information of each time point within the first target pentad based on the respective phenological information of the first and second target pentads, thus obtaining a phenological information time sequence for the first target pentad. The cloud terminal 20 is responsible for generating a phenological knowledge database based on the phenological information time sequence of the first target pentad, and for generating dynamic wallpapers for the in-vehicle system that change with time points based on the phenological knowledge database.

[0040] Specifically, the vehicle's onboard unit 10 calculates the solar ecliptic longitude by obtaining the current global reference time. It then compares the solar ecliptic longitude value with a predefined array of ecliptic longitude thresholds for the 24 solar terms to determine the current solar term. Based on the start and end times of the current solar term, the time period is precisely divided into three equal parts to determine the current phenological phase and its corresponding phenological information.

[0041] The method for generating live wallpapers for vehicles provided in this application will now be described in detail with reference to the accompanying drawings.

[0042] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for generating live wallpapers for in-vehicle systems, provided as an embodiment of this application. Figure 2 As shown, the method may include the following steps: S101. Determine the phenological information corresponding to each pentad in the lunar year.

[0043] In this embodiment, the lunar year includes 24 solar terms, and each solar term includes 3 pentads, resulting in a total of 72 pentads throughout the year. Each pentad corresponds to specific natural phenomena and phenological changes, such as the growth status of plants, the activity patterns of animals, and the characteristics of climate change. This phenological information is an important basic data for generating dynamic wallpapers.

[0044] The 24 solar terms of the Chinese lunar calendar, in chronological order, are: Beginning of Spring, Rain Water, Awakening of Insects, Spring Equinox, Pure Brightness, Grain Rain, Beginning of Summer, Lesser Fullness, Grain in Ear, Summer Solstice, Lesser Heat, Greater Heat, Beginning of Autumn, End of Heat, White Dew, Autumn Equinox, Cold Dew, Frost's Descent, Beginning of Winter, Lesser Snow, Greater Snow, Winter Solstice, Lesser Cold, and Greater Cold. Each solar term is divided into three pentads, each lasting approximately five days, called the first pentad, the second pentad, and the last pentad. For example, the three pentads of the Beginning of Spring are: the east wind thaws the ice, hibernating insects begin to stir, and fish rise to the surface carrying ice.

[0045] For each pentad, its corresponding phenological information needs to be determined. Phenological information can include the main natural phenomena, the state of flora and fauna, and climatic characteristics during that pentad. For example, the phenological information for the pentad "East Wind Thawing" can include: the east wind begins to blow, the ice and snow begin to melt, the ground begins to thaw, and plants begin to sprout.

[0046] In some embodiments, phenological information can be determined in several ways. One approach is to determine the typical phenological characteristics of each phenological pentad through statistical analysis based on historical meteorological data and phenological observation records. Another approach is to refer to ancient agricultural books and phenological classics to obtain traditional phenological descriptions. Furthermore, modern remote sensing technology and IoT sensors can be combined to monitor and collect phenological data in real time.

[0047] S102. Based on the phenological information of the first target phenological period and the second target phenological period in each phenological period, the phenological information of each time node in the first target phenological period is interpolated to obtain the phenological information time sequence of the first target phenological period.

[0048] In this embodiment, the first target phenological event and the second target phenological event are adjacent phenological events. Assume the first target phenological event is event A, and the second target phenological event is event B; event A and event B are two adjacent phenological events. The phenological information of event A is PA, and the phenological information of event B is PB. Within the time range of event A, there are multiple time nodes, such as t1, t2, t3, ..., tn. For each time node ti, interpolation calculation based on PA and PB is required to obtain the phenological information P(ti) for that time node. Various mathematical methods can be used for interpolation, such as linear interpolation, polynomial interpolation, and spline interpolation.

[0049] By interpolation, phenological information corresponding to each time point in the first target phenological period can be obtained, forming a phenological information time series. This time series reflects the continuous changes of phenological information in the time dimension, providing a refined data foundation for the subsequent generation of dynamic wallpapers.

[0050] S103. Generate a phenological knowledge database based on the phenological information time sequence of the first target phenological period.

[0051] In this embodiment, the phenological knowledge database is the core component for storing and managing phenological information and related data. The database design needs to consider factors such as data structuring, scalability, and query efficiency.

[0052] In some embodiments, the phenological knowledge database includes the visual attributes corresponding to each solar term and its three pentads. This phenological knowledge database contains entities such as solar terms, phenological phenomena, visual elements, colors, and atmosphere words, as well as their relationships. Vector encoding technology is used to convert features such as visual elements, colors, and atmosphere words into computer-processable vector representations, providing a basis for subsequent generation.

[0053] In some embodiments, entities include solar terms, phenological phenomena, visual elements (such as east wind, willow branches), colors, atmosphere words (such as budding, cool), and style tags (such as ink painting, realism).

[0054] In some embodiments, the relationship includes defining associations between entities, such as “solar term - contains phenology”, “phenology - manifests as - phenological phenomena”, “phenology - main color - color”, etc., and assigning weights to the “containing element” relationship.

[0055] In some embodiments, such as Figure 3 As shown, step S103, which generates a phenological knowledge database based on the time-series sequence of phenological information of the first target phenological period, may include: S1031. Based on the phenological information time series, determine the first target time series.

[0056] In the first target time series, the node information of the target time nodes constitutes the target information. The target information includes the visual element information corresponding to the phenological information of the target time nodes. Each target time node is a single node within the overall time series.

[0057] In this embodiment, for each time point in the phenological information time sequence, its phenological information needs to be converted into corresponding visual element information. Visual element information refers to visual descriptions that can be directly used for wallpaper generation, including image elements, color elements, and atmosphere elements.

[0058] For example, the corresponding visual elements for the phenological information "peach blossoms in full bloom" can include: image elements (images of peach blossoms, the shape of petals, the distribution of flowers, etc.), color elements (pink as the main color, accompanied by green leaves and brown branches), and atmosphere elements (bright spring sunshine, vibrant life, warm and gentle, etc.).

[0059] S1032. Generate a phenological knowledge database based on the first target time series.

[0060] In this embodiment, the data in the first target time series is stored in a database according to a predetermined data structure to form a complete phenological knowledge database. The database can take various forms, such as relational database, document database, or graph database, and the specific choice depends on the characteristics of the data and the application requirements.

[0061] In some embodiments, the phenological knowledge database may include a time node table, a phenological information table, a visual element table, a wallpaper style table, and an agricultural culture table.

[0062] The time node table stores basic information about time nodes, such as timestamp, solar term, and pentad.

[0063] The phenological information table stores phenological information corresponding to each time point, such as descriptions of natural phenomena and the status of plants and animals.

[0064] The visual element table stores visual element information corresponding to each time point, including image elements, color elements, and atmosphere elements.

[0065] The wallpaper style table stores different wallpaper styles and their corresponding visual parameter settings.

[0066] The agricultural culture table stores agricultural culture information corresponding to each time point or solar term, such as agricultural activities, traditional customs, health preservation concepts, poems and songs.

[0067] By linking and querying these data tables, complete information needed for any point in time can be quickly obtained, providing data support for the generation of dynamic wallpapers.

[0068] S104. Based on the phenological knowledge database, generate dynamic wallpapers for the vehicle system that change with time nodes.

[0069] In some embodiments, such as Figure 4 As shown, step S104, based on the phenological knowledge database, generating a dynamic in-vehicle wallpaper that changes with time nodes may include: S1041. Determine the wallpaper style.

[0070] In this embodiment, wallpaper style refers to the overall visual style and artistic expression of the dynamic wallpaper. The wallpaper style can be determined in several ways: One approach is for vehicle occupants (such as drivers or passengers) to actively select the wallpaper style. The in-vehicle infotainment system can provide a wallpaper style selection interface, displaying a variety of available styles, such as realistic, ink wash, cartoon, abstract, and retro styles. Users can choose a suitable wallpaper style based on their personal preferences and the car's interior decor.

[0071] Another approach is to determine the wallpaper style based on the in-vehicle infotainment system's historical wallpapers. The system can record the user's past wallpaper style preferences, analyze these preferences using machine learning algorithms, and automatically recommend or determine the most suitable wallpaper style for the current user. For example, if a user frequently chooses ink painting style wallpapers, the system may tend to recommend or automatically select that style.

[0072] S1042. Based on the wallpaper style and the visual element information corresponding to the current time node and multiple subsequent time nodes in the phenological knowledge database, determine the target visual element information corresponding to the current time node and multiple subsequent time nodes.

[0073] In this embodiment, the system first obtains the current time node, and then queries the phenological knowledge database for the visual element information of the current time node and several subsequent time nodes (such as key time nodes in the next 1 hour, 6 hours, 12 hours or 24 hours).

[0074] For each time point, the system stylizes the visual element information in the database according to the determined wallpaper style to obtain the target visual element information. Stylization can include various techniques such as color adjustment, line processing, texture addition, and lighting effect adjustment.

[0075] For example, if the visual element information for a certain time point in the database is "peach blossoms in full bloom, pink petals, green leaves", and the selected wallpaper style is "ink style", then the target visual element information after stylization may become "ink peach blossoms, light ink petals, dark ink branches, and white background".

[0076] S1043. Based on the target visual element information, determine the wallpaper prompt words corresponding to the current time node and multiple subsequent time nodes.

[0077] In this embodiment, wallpaper prompts refer to text descriptions or parameter instructions used to guide wallpaper generation. Generating prompts requires converting visual element information into a form that the generation algorithm can understand and execute.

[0078] The prompts can include information such as subject description, style description, color description, composition description, and atmosphere description. The subject description can describe the main elements of the wallpaper, such as "blooming peach blossoms" or "fluttering butterflies." The style description can specify the art style, such as "ink painting style" or "impressionist style." The color description can specify the color scheme, such as "pink and green as the main colors" or "warm color gradient." The composition description can specify the layout, such as "central composition" or "rule of thirds." The atmosphere description can specify the emotional atmosphere, such as "warm and romantic" or "fresh and natural."

[0079] For example, based on the target visual element information of the above-mentioned ink-wash style peach blossoms, the generated wallpaper prompt might be: "Ink-wash style, blooming peach blossoms, light ink petals, dark ink branches, blank background, central composition, fresh and elegant atmosphere."

[0080] S1044. Based on the wallpaper prompt, generate static wallpapers corresponding to the current time node and multiple subsequent time nodes.

[0081] In this embodiment, static wallpapers can be generated using a variety of techniques, including traditional computer graphics methods and modern artificial intelligence generation methods.

[0082] Traditional methods include image compositing, filtering, and rendering techniques. Image compositing involves combining and arranging pre-designed image elements according to prompts. Filtering applies various artistic filters and effects to a base image. Rendering techniques use 3D rendering engines to generate high-quality images.

[0083] Modern artificial intelligence generation methods can generate corresponding images based on text prompts.

[0084] Regardless of the method used, the generated static wallpaper should accurately reflect the requirements of the prompt, and meet the predetermined standards in terms of visual quality, artistic expression, and technical parameters.

[0085] S1045. Perform transition rendering on the static wallpaper to obtain the dynamic wallpaper for the vehicle system.

[0086] In this embodiment, transition rendering refers to creating a smooth transition effect between multiple static wallpapers, making the entire live wallpaper look coherent and natural. Transition rendering techniques can include fade-in / fade-out, shape transformation, particle effects, and lighting transitions.

[0087] Fade in / fade out involves gradually decreasing the transparency of the previous wallpaper while increasing the transparency of the next wallpaper between two wallpapers.

[0088] Shape transformation is the process of gradually transforming elements in the previous wallpaper into corresponding elements in the next wallpaper.

[0089] Particle effects are created using particle systems to create transitions between elements, such as falling petals or flowing clouds.

[0090] Light and shadow transitions achieve natural scene changes through variations in lighting and shadows.

[0091] Transition rendering requires consideration of multiple factors, including timing control, visual effect optimization, and performance balance. The transition time should not be too long, as this will make the change feel slow to the user. Nor should it be too short, as this will create a jarring visual effect. Typically, the transition time can be set between a few seconds and a dozen seconds.

[0092] Through the above steps, the final generated in-vehicle dynamic wallpaper can change naturally with the time, which not only reflects the rich connotations of the 24 solar terms and 72 pentads in traditional culture, but also provides a smooth and beautiful visual experience, effectively improving the user experience of the in-vehicle infotainment system.

[0093] In some embodiments, the target information includes the visual element information corresponding to the phenological information of the target time point under each wallpaper style in at least one wallpaper style.

[0094] In this embodiment, this means that for phenological information at the same point in time, the system can pre-calculate and store visual element information under multiple wallpaper styles. For example, for the phenological information of "Qingming Festival", visual element information in multiple styles such as realistic style, ink painting style, and cartoon style can be prepared in advance.

[0095] When a user selects a wallpaper style, the system can directly retrieve the corresponding visual element information from the database, eliminating the need for real-time style conversion and thus improving response speed. Furthermore, pre-processing ensures that visual elements within the same style maintain a consistent artistic style and presentation across different time periods. Additionally, users can easily compare the effects of the same phenological information under different styles and choose the style they prefer.

[0096] In some embodiments, the target information includes visual element information and agricultural culture information under the solar term of the target time node; wherein, agricultural culture information includes at least one of the following: agricultural activities, traditional customs, health preservation concepts, and poems and songs.

[0097] In this embodiment, the in-vehicle dynamic wallpaper is not only a visual artwork but also a carrier of cultural dissemination. Specifically, agricultural activity information can include suitable agricultural production activities for the current season, such as "sowing and raising seedlings around the Spring Equinox" and "planting melons and beans around Qingming Festival." This information can be displayed in text form at an appropriate location on the wallpaper or implied through image elements.

[0098] Information about traditional customs can include traditional festivals and folk activities related to the current solar term, such as "eating dumplings on the Winter Solstice" and "sweeping tombs during Qingming Festival." This information can be conveyed through scene elements, figures, or decorative patterns in the wallpaper.

[0099] Health and wellness information can include appropriate methods and precautions for the current season based on Traditional Chinese Medicine theory and wisdom, such as "nourishing the liver in spring" and "nourishing the heart in summer." This information can be incorporated into the wallpaper design as helpful tips.

[0100] The information on poetry and literature can include classical poems describing the current solar term or phenology. These poems can be presented in the form of calligraphy art on the wallpaper, adding a cultural touch.

[0101] The integration of agricultural culture information transforms in-vehicle live wallpapers into mobile cultural classrooms, allowing users to subtly learn about and understand excellent traditional Chinese culture while using their vehicles, achieving a perfect fusion of technology and culture.

[0102] In some embodiments, the phenological information corresponding to each phenological period is the phenological information corresponding to each phenological period in the target region; wherein, the target region is each of at least one region.

[0103] In this embodiment, climatic conditions and phenological phenomena vary significantly across different regions. For example, the "Beginning of Spring" in South China may already be a time of warm weather and blooming flowers, while in Northeast China it may still be a time of ice and snow. Therefore, determining the corresponding phenological information for different regions is crucial to ensuring the authenticity and accuracy of the wallpaper.

[0104] In some embodiments, the system needs to establish a corresponding phenological information database for each target region. These databases can be constructed based on various data sources such as historical meteorological data, phenological observation records, and local chronicles for that region.

[0105] In some embodiments, users can select a target region based on their actual location or the area of ​​interest. The system can also automatically determine the vehicle's location and load corresponding phenological information using Global Positioning System (GPS) or other positioning technologies.

[0106] This localized processing of phenological information not only enhances the accuracy and realism of the wallpapers but also provides convenience for cross-regional travel. When users drive from the north to the south, the car's wallpaper can automatically adjust to reflect the actual local phenological conditions, providing users with an immersive experience of regional culture.

[0107] In some embodiments, visual element information includes: image elements representing phenological phenomena, color elements, and atmosphere elements.

[0108] In this embodiment, image elements refer to specific image content that directly depicts phenological phenomena, and may include plant elements, animal elements, weather elements, terrain elements, and human elements. Plant elements may include different parts and states of plants such as flowers, leaves, fruits, and seeds. Animal elements may include the activities and postures of animals such as birds, insects, and mammals. Weather elements may include weather phenomena such as the sun, moon, stars, clouds, rain, snow, and fog. Terrain elements may include landform features such as mountains, rivers, lakes, and plains. Human elements may include elements related to human activities such as agricultural tools, buildings, and human activities.

[0109] Color elements refer to the overall color scheme and color matching of the wallpaper, which can include the main color, secondary colors, accent colors, color saturation, and color brightness. Atmosphere elements refer to elements that create a specific emotional atmosphere and environmental feeling, which can include lighting effects, weather atmosphere, seasonal atmosphere, emotional atmosphere, and cultural atmosphere.

[0110] By organically combining the above three elements, the visual connotation of phenological information can be fully and accurately expressed, laying the foundation for generating high-quality in-vehicle dynamic wallpapers.

[0132] For example, the aforementioned computer-readable storage media may include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), optical discs (e.g., compact disks (CDs), digital versatile disks (DVDs), etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memory (EPROMs), cards, sticks, or key drives, etc.).

[0135] The vehicle provided in this application may be a passenger vehicle or a freight vehicle, and may also be an electric vehicle or a hybrid vehicle. This application does not limit the specific purpose or power type of the vehicle, and the choice can be made according to actual needs.

[0136] A vehicle consists of a body and wheels. The body is used for passengers and for carrying goods, while the wheels are mounted underneath the body to support it and allow it to roll on the road, thus enabling the vehicle to move.

[0137] In some possible examples, the vehicle is equipped with a control system, which typically adopts a layered distributed architecture. From the bottom layer to the top layer, it can be roughly divided into a perception layer, a control layer, a coordination layer, and an interaction layer. The layers communicate with each other through an in-vehicle network.

[0138] The perception layer mainly consists of various sensors distributed inside and outside the vehicle, including but not limited to external environment cameras, millimeter-wave radar, lidar, ultrasonic sensors, in-vehicle driver monitoring cameras, microphone arrays, and various vehicle status sensors (such as wheel speed sensors, inertial measurement units, temperature sensors, etc.). The perception layer is responsible for collecting multi-dimensional data such as the vehicle's own operating status, driver behavior, and external driving environment in real time.

[0139] The control layer consists of dozens to hundreds of electronic control units (ECUs), distributed across multiple functional domains including powertrain, chassis, body, intelligent driving, and infotainment. Each ECU embeds real-time control software that performs closed-loop control of the vehicle's actuators based on preset control strategies or upper-level commands, and generates corresponding alarm signals when abnormal conditions are detected. Typical ECUs include the engine control unit, transmission control unit, brake control unit, steering control unit, vehicle stability control unit, airbag control unit, intelligent driving domain controller, and in-vehicle infotainment unit.

[0140] The coordination layer typically exists in the form of a domain controller or a central computing platform, responsible for cross-domain data fusion, global state management, and collaborative decision-making. The coordination layer centrally processes and schedules the sensing data and control commands that were originally scattered across various functional domains, connecting downwards to various electronic control units and supporting human-machine interaction functions upwards.

[0141] The interaction layer mainly includes in-cabin display devices (such as instrument panel, central control screen, head-up display), voice interaction system, haptic feedback device, etc., which are responsible for presenting vehicle status, warning information and driving suggestions to the driver in the form of visual, auditory or tactile, while receiving the driver's touch, voice and other input commands.

[0142] Data transmission and interaction between different layers are achieved through the vehicle bus network. Common vehicle bus protocols include CAN (Controller Area Network), CAN FD (CAN with Flexible Data-Rate), LIN (Local Interconnect Network), FlexRay, and vehicle Ethernet, which supports high-bandwidth data transmission. Among these, CAN and CAN FD buses are widely used for communication in real-time control domains such as powertrain and chassis, while vehicle Ethernet is gradually being applied to high-bandwidth sensor data transmission in the intelligent driving domain and multimedia interaction scenarios in the cockpit domain.

[0143] In some possible examples, the in-vehicle infotainment unit, as the core of the in-vehicle computing platform, is equipped with a processor and memory to execute the in-vehicle dynamic wallpaper generation method provided in the embodiments of this application.

[0144] For example, the control device of this application is arranged in the vehicle infotainment unit.

[0145] For example, the in-vehicle infotainment unit is equipped with multiple functional modules for performing the various method steps.

[0146] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
