Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more particularly to methods, apparatus, vehicles, software products, and storage media for generating in-vehicle wallpapers. Background Technology

[0002] With the development of smart cockpit technology, the in-vehicle human-machine interaction experience is receiving increasing attention. Wallpapers, as the main visual interface of the vehicle's infotainment system, not only beautify the interface but also serve as an important medium for users' personalized expression and emotional connection. Currently, in-vehicle wallpapers are mainly displayed based on pre-set, fixed wallpapers, resulting in rigid content that cannot adapt to individual user differences. Summary of the Invention

[0003] This disclosure provides a method, apparatus, vehicle, program product, and storage medium for generating in-vehicle wallpapers, which can generate wallpaper content that matches user information based on user information, thereby improving the personalization of in-vehicle wallpapers.

[0004] Firstly, this application provides a method for generating in-vehicle wallpapers. The method includes: determining the profile information of the occupants in the vehicle; wherein the profile information includes their zodiac sign, age, and date of birth; if the difference between the current date and the date of birth is less than a preset birthday difference, determining birthday elements based on the birthday difference, zodiac sign, age group, and birthday celebration knowledge graph; wherein the birthday elements include birthday icons, birthday atmosphere words, birthday blessing statements, and birthday colors; generating birthday prompt text based on the birthday elements; and generating in-vehicle wallpapers using the birthday prompt text.

[0005] Based on this implementation method, by introducing the difference in birth dates as the trigger condition for generating in-vehicle wallpapers, and combining the occupant's zodiac sign, age and other profile information as well as birthday knowledge graphs, the wallpaper generation is made to have event correlation in the time dimension and attribute correspondence for specific occupants in the content dimension, thereby improving the correlation between wallpaper content and occupant personal information.

[0006] In some embodiments, birthday celebration elements are determined based on the difference in birthdates, zodiac sign, age group, and birthday celebration knowledge graph, including: determining the passenger's level of expectation for the birthday celebration based on the difference in birthdates and age group; and determining the birthday celebration elements based on the level of expectation, zodiac sign, and birthday celebration knowledge graph.

[0007] Based on this implementation method, the difference in birthdays and age groups are used as inputs. By quantifying the emotional state of passengers towards their birthdays, the corresponding level of expectation of the passengers is obtained. The level of expectation is used as the quantitative basis for the selection of elements in the subsequent wallpapers, avoiding direct output based on non-fixed rules. This makes the selection results of birthday celebration elements fit the psychological expectations of passengers and enhances passengers' sense of identification with the wallpaper content.

[0008] In some embodiments, birthday celebration elements are determined based on the level of anticipation, zodiac signs, and a birthday celebration knowledge graph, including: determining the proportion of birthday celebration colors and zodiac-related birthday celebration icons based on zodiac signs; determining a first number of birthday celebration icons and a second number of zodiac-related birthday celebration icons based on the proportions; wherein the birthday celebration icons include zodiac-related birthday celebration icons; selecting birthday celebration icons from the subgraphs corresponding to zodiac signs in the birthday celebration knowledge graph based on the first and second numbers; and selecting birthday celebration atmosphere words and birthday blessing statements from the subgraphs based on the level of anticipation; wherein the atmosphere words and blessing statements in the subgraphs are all marked with the applicable level of anticipation.

[0009] Based on this implementation method, the visual proportion of exclusive elements in the wallpaper is adjusted according to the constellation in terms of birthday icons, and the corresponding words and phrases are selected according to the level of expectation in terms of birthday text (atmospheric words, blessings), so that the wallpaper corresponds to the occupant attributes in both visual layout and semantic content, thereby improving the matching degree between the overall style of the wallpaper and the personal information of the occupants.

[0010] In some embodiments, the portrait information further includes: permanent residence; the birthday icon further includes a regional icon; selecting a birthday icon from the subgraph corresponding to the constellation in the birthday knowledge graph based on a first quantity and a second quantity, including: determining the vehicle's location; determining a regional transfer coefficient based on regional cultural differences and / or regional climate differences between the permanent residence and the location; wherein the regional transfer coefficient is used to indicate the regional transfer coefficient of the icon's regional style from the permanent residence to the location; the regional transfer coefficient is positively correlated with the degree of difference in regional cultural differences and / or regional climate differences; selecting a birthday icon from the subgraph corresponding to the constellation in the birthday knowledge graph based on the first quantity, the second quantity, the permanent residence, the location, and the regional transfer coefficient.

[0011] Based on this implementation method, the regional cultural and climatic differences between the permanent residence and the place of residence are quantified into a regional transfer coefficient. The composition ratio of regional elements in the wallpaper is adjusted according to this coefficient, so that the regional style of the wallpaper is adjusted accordingly as the vehicle travels in different areas. Passengers can perceive the correspondence between the vehicle interface and the external geographical environment while driving, thus enhancing their sense of immersion.

[0012] In some embodiments, selecting birthday icons from the subgraphs corresponding to constellations in the birthday celebration knowledge graph based on a first quantity, a second quantity, permanent residence, place of origin, and regional transfer coefficient includes: determining a third quantity of regional icons corresponding to the place of origin and a fourth quantity of regional icons corresponding to the permanent residence based on the first quantity, the second quantity, and the regional transfer coefficient; selecting constellation-related birthday icons from the subgraphs based on the first quantity; selecting regional icons corresponding to the place of origin from the subgraphs based on the third quantity; and selecting regional icons corresponding to the permanent residence from the subgraphs based on the fourth quantity.

[0013] Based on this implementation method, the number of different icons is adjusted by using a regional transfer coefficient, so that the composition ratio of the permanent location icon and the corresponding location icon in the wallpaper changes accordingly with the change of the vehicle's driving position. There is a correspondence between the regional style of the wallpaper seen by the passenger on the vehicle screen and the current geographical location, which enhances the passenger's driving immersion.

[0014] In some embodiments, the image information further includes: wallpaper preference style; generating birthday greeting text based on birthday elements, including: determining composition rules based on constellations; and generating birthday greeting text based on composition rules, wallpaper preference style, and birthday elements.

[0015] Based on this implementation method, the layout of the screen is organized according to the corresponding composition rules, and the occupants' preset wallpaper preferences are incorporated into the generation parameters, so that the final output wallpaper corresponds to the occupant's portrait in both content organization and visual style, thereby enhancing the personalization of the wallpaper.

[0016] In some embodiments, determining the occupant profile information in the vehicle includes: performing multi-dimensional identity recognition of the occupant based on the occupant's captured images, seat memory information, network information of the handheld terminal, and other auxiliary information; wherein, when the occupant is the driver, the other auxiliary information includes driving style information; and retrieving the occupant profile information from the local profile database based on the recognition results of the multi-dimensional identity recognition.

[0017] Based on this implementation method, the identity of passengers is identified by integrating data from multiple sources. After identification, the profile information is retrieved from the local database for wallpaper generation, so that the personalized processing of wallpaper content has an accurate data input basis.

[0018] Secondly, this application provides a vehicle wallpaper generation device, including: a first determining module, a second determining module, a first generating module, and a second generating module.

[0019] The first determining module is used to determine the profile information of the occupants in the vehicle, including their zodiac sign, age, and date of birth.

These birthday celebration elements include birthday celebration icons, birthday celebration atmosphere words, birthday celebration blessing statements, and birthday celebration colors. The first generating module is used to generate birthday celebration prompt text based on the birthday celebration elements. The second generating module is used to generate in-vehicle wallpaper using the birthday celebration prompt text.

[0020] In some embodiments, the second determining module is specifically used to determine the passenger's level of anticipation for the birthday celebration based on the difference in birthdays and age groups; and to determine the elements of the birthday celebration based on the level of anticipation, zodiac sign, and birthday celebration knowledge graph.

[0021] In some embodiments, the second determining module is specifically used to determine the proportion of birthday celebration colors and constellation-related birthday celebration icons based on constellations; determine a first number of birthday celebration icons and a second number of constellation-related birthday celebration icons based on the proportions; wherein, the birthday celebration icons include constellation-related birthday celebration icons; select birthday celebration icons from the constellation-corresponding subgraphs in the birthday celebration knowledge graph based on the first and second numbers; and select birthday celebration atmosphere words and birthday blessing statements from the subgraphs based on the level of expectation; wherein, the atmosphere words and blessing statements in the subgraphs are all marked with the applicable level of expectation.

[0022] In some embodiments, the portrait information further includes: permanent residence; the birthday icon further includes a regional icon; a second determining module is specifically used to determine the vehicle's location; based on the regional cultural differences and / or regional climate differences between the permanent residence and the location, a regional transfer coefficient is determined; wherein, the regional transfer coefficient is used to indicate the regional transfer coefficient of the icon's regional style from the permanent residence to the location; the regional transfer coefficient is positively correlated with the degree of difference in regional cultural differences and / or regional climate differences; based on the first quantity, the second quantity, the permanent residence, the location, and the regional transfer coefficient, a birthday icon is selected from the subgraph corresponding to the constellation in the birthday knowledge graph.

[0023] In some embodiments, the second determining module is specifically used to determine, based on the first quantity, the second quantity, and the regional transfer coefficient, the third quantity of regional icons corresponding to the place of origin and the fourth quantity of regional icons corresponding to the place of residence; select constellation-related birthday icons from the sub-map based on the first quantity; select regional icons corresponding to the place of origin from the sub-map based on the third quantity; and select regional icons corresponding to the place of residence from the sub-map based on the fourth quantity.

[0024] In some embodiments, the portrait information further includes: wallpaper preference style; a first generation module, specifically used to determine composition rules based on constellations; and to generate birthday greeting text based on the composition rules, wallpaper preference style, and birthday elements.

[0036] With the development of smart cockpit technology, the in-vehicle human-machine interaction experience is receiving increasing attention. Wallpapers, as the main visual interface of the vehicle's infotainment system, not only beautify the interface but also serve as an important medium for users' personalized expression and emotional connection. Currently, in-vehicle wallpapers are mainly displayed based on pre-set, fixed wallpapers, resulting in rigid content that cannot adapt to individual user differences.

[0037] To address the aforementioned technical problems, this disclosure provides a method for creating in-vehicle wallpapers. The method involves: determining the profile information of the occupants in the vehicle; wherein the profile information includes their zodiac sign, age, and date of birth; if the difference between the current date and the date of birth is less than a preset birthday difference, determining birthday celebration elements based on the birthday difference, zodiac sign, age group, and birthday celebration knowledge graph; wherein the birthday celebration elements include birthday celebration icons, birthday celebration atmosphere words, birthday celebration blessing statements, and birthday celebration colors; generating birthday celebration prompt text based on the birthday celebration elements; and generating in-vehicle wallpaper using the birthday celebration prompt text.

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

[0039] See Figure 1 This is a schematic diagram of the architecture of a vehicle wallpaper generation system provided in an embodiment of this disclosure. Figure 1 As shown, the in-vehicle wallpaper generation system includes: in-vehicle terminal 10 and cloud terminal 20.

[0040] The in-vehicle wallpaper generation system provided in this application embodiment can be applied to electric vehicles, hybrid vehicles, plug-in hybrid vehicles, fuel cell vehicles, etc. Please refer to... Figure 1 The system includes: vehicle terminal 10 and cloud terminal 20, and communication connection between vehicle terminal 10 and cloud terminal 20.

[0041] The vehicle-mounted terminal 10 is configured to: perform occupant identification and profile loading, current date and location awareness, birthday celebration trigger determination, local reasoning retrieval of birthday celebration elements, birthday celebration prompt text generation, and receive cloud-generated wallpapers for rendering and wallpaper updates.

[0042] Cloud 20 is configured to: store and manage occupant profile data, provide user identity comparison and verification services; and when the vehicle terminal 10 cannot complete local retrieval or requires stronger computing power, perform birthday celebration knowledge graph retrieval and matching based on the profile information uploaded by the vehicle terminal, extract birthday celebration elements and return them to the vehicle terminal; or call the image generation service to generate vehicle terminal wallpaper based on the birthday celebration prompt text uploaded by the vehicle terminal, and send the generated wallpaper to the vehicle terminal 10 for display.

[0043] It is understood that the application scenarios of the embodiments of this disclosure are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0044] The method for generating in-vehicle wallpapers provided in this embodiment will be described in detail below.

[0045] This disclosure provides a method for generating in-vehicle infotainment wallpapers, such as... Figure 2 As shown, the method includes the following steps: S201. Determine the portrait information of the occupants in the vehicle.

[0046] The profile information includes zodiac sign, age, and date of birth. All of the above-mentioned profile information of the passengers was collected and obtained with their authorization and consent.

[0047] To enhance the personalization of the generated wallpapers, it is necessary to first determine the portrait information of the occupants in the vehicle, and then execute the subsequent wallpaper generation process based on the portrait information.

[0048] It should be noted that the occupant can be any occupant in the vehicle, such as the driver, front passenger, or rear passenger. This embodiment does not limit the specific seat position of the occupant.

[0049] As one possible implementation, the aforementioned determination of the occupants' profile information can be achieved through automatic user identification. For example, facial images of the occupants can be captured using an in-vehicle camera, facial feature vectors can be extracted using a facial recognition model, and then compared with a cloud-based user database to confirm their identity. If identification is successful, the system loads the user's profile data from the cloud; if identification fails, it switches to manual login or guest mode.

[0050] For example, taking passenger Li Si as an example, his pre-stored profile information includes: born in 1998 (age 28), zodiac sign Leo (birthday August 15th), and birthday date August 15th. After Li Si enters the vehicle, the in-vehicle camera captures his facial image, extracts a 512-dimensional facial feature vector using a deep learning model, and calculates cosine similarity with pre-stored templates in the cloud library. If the similarity exceeds a preset threshold (e.g., 0.75), his identity is successfully confirmed, and the vehicle system loads Li Si's complete profile data from the cloud for subsequent birthday celebration elements. If the similarity is below the threshold, the system switches to a manual login interface, where the passenger logs in manually and the profile is loaded.

[0051] As a possible approach to further improve recognition accuracy, in addition to the aforementioned facial recognition, multimodal auxiliary information such as seat memory position, mobile phone Bluetooth key, and driver habits can be integrated for cross-verification to comprehensively determine the current occupant's identity.

[0052] S202. If the difference between the current date and the birthday date is less than the preset birthday difference, determine the birthday celebration elements based on the birthday difference, zodiac sign, age group, and birthday celebration knowledge graph.

[0053] The elements for celebrating birthdays include birthday icons, words that evoke a festive atmosphere, birthday wishes, and birthday colors.

[0054] As one possible implementation, the current date can be obtained through the real-time clock module built into the vehicle system or by synchronizing with a satellite time server; when the vehicle travels across time zones, the system also performs time zone correction by combining the longitude information of the vehicle's current location.

[0055] Birthday difference refers to the difference in the number of days between the current date and the passenger's birthday in the year in which the current date is located: if the current date is before the passenger's birthday in the current year, the birthday difference is positive; if it is after the current date, the birthday difference is negative; if it is the birthday, the birthday difference is 0.

[0056] The preset birthday difference is used to determine whether the current date has entered the birthday celebration period. When the birthday difference is less than the preset birthday difference, the birthday celebration element determination process is triggered. For example, based on different value ranges of the birthday difference, it can be divided into a warm-up period (4-6 days), an approaching period (1-3 days), the birthday itself (0 days), and a completion period (-1 to -3 days). For example, the preset birthday difference is 6 days, that is, the birthday celebration element determination process is triggered when the birthday difference is in the range of -3 days to 6 days.

[0057] Upon triggering, the system retrieves the birthday difference, zodiac sign, and age range. The birthday celebration knowledge graph is a pre-built structured knowledge base containing multiple entity nodes and relational edges, including zodiac sign nodes, age range nodes, birthday icon nodes, birthday atmosphere word nodes, birthday blessing sentence nodes, and birthday color nodes. The system uses the birthday difference, zodiac sign, and age range as query conditions to perform a search and match within the birthday celebration knowledge graph, extracting the corresponding birthday icon, birthday atmosphere word, birthday blessing sentence, and birthday color.

[0058] For example, taking passenger Li Si as an example, his zodiac sign is Leo, his age is 28 (youth segment), and his birthday is August 15th. If the current date is August 10th, then the birthday difference is 5 days (warm-up period), which is less than the preset birthday difference of 6 days. The system uses "birthday difference of 5 days (warm-up period), zodiac sign Leo, age segment youth" as conditions to search the birthday celebration knowledge graph, extracting the birthday celebration icon as a cartoon sun and cake, the birthday celebration atmosphere word as "brilliant", the birthday blessing sentence as "May you shine as brightly as the sun, happy birthday", and the birthday celebration colors as gold and orange.

[0059] S203. Generate birthday celebration prompt text based on birthday celebration elements.

[0060] The prompt text is a natural language description used to generate the input image model. The system combines the identified birthday celebration elements according to the preset prompt text template to generate the birthday celebration prompt text.

[0061] For example, the birthday elements extracted by Li Si are: birthday colors "gold and orange", birthday icons "cartoon sun and cake", birthday atmosphere word "brilliant", and birthday blessing "May you shine as brightly as the sun, happy birthday". The system fills these elements into a preset template and generates birthday prompt text: "Generate a birthday image with a brilliant atmosphere, gold and orange tones, containing cartoon sun and cake elements, and the background reads 'May you shine as brightly as the sun, happy birthday'".

[0062] In some embodiments, the prompt word template can also be adaptively adjusted according to age groups, adding modifiers such as "lively" and "fashionable" for young people and "elegant" and "textured" for middle-aged people, so that the generated wallpaper is more in line with the age characteristics of the passengers.

[0063] S204. Generate car wallpaper using birthday greeting text.

[0064] The generated birthday greeting text is input into a preset image generation model, which then outputs the corresponding car wallpaper.

[0065] For example, the image generation model can be a diffusion model, such as the Stable Diffusion model, deployed on the in-vehicle infotainment system or a cloud server. If deployed on the in-vehicle infotainment system, the system encodes the prompt text into a conditional vector using a text encoder, iteratively denoises it using a denoising network, and then restores it to a pixel-space image using a decoder. If deployed on the cloud, the in-vehicle infotainment system sends the prompt text to the cloud, and the generated image is then sent back to the in-vehicle infotainment system. The generated wallpaper image is adapted to the in-vehicle infotainment system screen resolution and automatically set as the in-vehicle desktop wallpaper or standby wallpaper.

[0066] like Figure 3 As shown, S201 includes the following S2011-S2012: S2011. Based on the occupant's captured images, seat memory information, handheld terminal network information, and other auxiliary information, perform multi-dimensional identity recognition of the occupant.

[0067] For example, seat memory information may include parameters such as seat fore-and-aft position, backrest angle, and seat cushion height. Seat memory information may be collected by seat position sensors and pre-bound to user accounts.

[0068] For example, the network information of the handheld terminal may include the mobile phone's Bluetooth MAC address and the device identifier when the vehicle-to-everything (V2X) interconnection function (such as CarPlay or Android Auto) is connected. The network information of the handheld terminal can be obtained through near-field communication.

[0069] For example, other auxiliary information may include the occupant's weight information (collected by seat pressure sensors) and height information (collected by in-vehicle height sensors or estimated based on seat position), as well as the occupant's historical travel time preference information.

[0070] As one possible implementation, when the occupant is the driver, other auxiliary information, including driving style information such as average acceleration and braking frequency, can be collected by onboard sensors.

[0071] As one possible implementation, multi-dimensional identity recognition based on the aforementioned parameters can be achieved by using facial recognition results as the primary method and other dimensions as supplementary information for comprehensive judgment. Facial recognition is performed on images of the occupant. When the facial recognition confidence level is high, the identity is directly confirmed. When the facial recognition confidence level is insufficient, seat memory information, handheld terminal network information, and other auxiliary information are introduced for cross-validation. The matching results of each dimension are comprehensively scored, and the candidate identity with the highest score is used as the recognition result. If no match can be found in any dimension, the user is determined to be unregistered, and the system switches to manual login or guest mode. This application does not limit the specific weighting of each dimension in the comprehensive scoring; in practical applications, it can be flexibly adjusted according to sensor confidence levels and scenario requirements.

[0072] S2012. Based on the recognition results of multi-dimensional identity recognition, retrieve the occupant's portrait information from the local portrait database.

[0073] As one possible implementation, multi-dimensional identity recognition can output the occupant's identification number. Using the occupant's identification number as an index, the system can retrieve the user's pre-stored profile information record from the local profile database and load it into memory for use in the subsequent birthday celebration element determination process. If the recognition result is an unregistered user, the system's default profile information will be loaded or the occupant will be prompted to manually enter it.

[0074] In some embodiments, S201 above can be implemented as follows: determining the passenger's level of expectation for the birthday celebration based on the difference in birthdays and age groups; and determining the elements of the birthday celebration based on the level of expectation, zodiac sign, and birthday celebration knowledge graph.

[0075] It should be understood that determining the level of expectation can quantify passengers' emotional needs for birthday celebrations at different times, thereby allowing for more targeted selection of birthday elements for in-vehicle wallpapers, avoiding mechanical pushes, and enhancing the personalized experience.

[0076] One possible implementation is to assign different expectation weights based on age group and birthday difference, and then calculate the level of expectation by weighting these weights. This level of expectation, along with the zodiac sign, can then be used as an index to retrieve matching birthday celebration elements from the birthday celebration knowledge graph. For example, expectations are weighted higher during adolescence and lower during middle and old age, with closer birthday differences resulting in higher weights. This application does not limit the method for setting these expectation weights.

[0077] like Figure 4 As shown, the above determination of birthday celebration elements based on expectation level, zodiac sign, and birthday celebration knowledge graph can be implemented through the following steps S301-S304: S301. Based on the constellation, determine the proportion of birthday celebration colors and constellation-related birthday celebration icons.

[0078] One possible implementation involves determining a color swatch matrix and graphic element weights corresponding to each zodiac sign. The color swatch matrix records the primary and secondary colors of the sign, and the birthday colors are determined based on this matrix, serving as the color benchmark for subsequent visual presentation. The graphic element weights record the zodiac symbol and the weight values ​​of each associated graphic, with each weight reflecting the importance of the corresponding graphic in the birthday celebration scene associated with that sign. Based on these graphic element weights, the weight values ​​of all graphic elements belonging to that sign (such as zodiac symbols, guardian star graphics, and exclusive emblems) are summed to obtain a total zodiac weight. This sum is then divided by the total weight of all graphic elements to calculate the proportion of zodiac-related birthday icons among all birthday icons. This proportion controls the ratio of zodiac-related icons to other icons in the subsequently selected birthday icons. A higher proportion results in more elements strongly related to the sign in the final birthday icons, enhancing the sense of zodiac exclusivity.

[0079] It should be noted that the color palette matrix and graphic element weights corresponding to each constellation are all preset. This application does not limit the specific content of the color palette matrix and graphic element weights, and they can be calibrated according to the preferences of the crew in practical applications.

[0080] S302. Determine the first number of birthday celebration icons and the second number of zodiac-related birthday celebration icons based on the proportion.

[0081] Among them, the birthday icons include those related to the zodiac sign.

[0082] For example, obtain the preset total number of birthday icons, multiply the total by the percentage to get the second quantity, and subtract the second quantity from the total to get the first quantity.

[0083] S303. Based on the first and second quantities, select birthday icons from the subgraphs corresponding to the constellations in the birthday celebration knowledge graph.

[0084] For example, use constellations as indexes to locate sub-maps, select constellation-related birthday icons according to the second quantity, and select non-constellation-related birthday icons according to the first quantity.

[0085] S304. Based on the level of expectation, select birthday-themed words and birthday wishes from the sub-map.

[0086] Among them, the atmosphere words and blessing phrases in the sub-maps are all marked with the applicable expectation level.

[0087] For example, using the calculated level of expectation as an index, the system matches and selects birthday-themed words and birthday wishes that correspond to the current level of expectation from the sub-map.

[0088] In some embodiments, the profile information further includes: permanent residence; the birthday icon also includes a regional icon. The permanent residence refers to the geographical location where the occupant resides or primarily engages in activities. This can be determined through methods such as obtaining the occupant's frequently used travel areas via an in-vehicle positioning system, through manually set home or work addresses, or through statistical analysis of long-term vehicle parking locations. The regional icon refers to a visual symbol associated with the regional cultural characteristics of the permanent residence, such as snowflakes and ice crystals representing the north, flowers and green leaves representing the south, blue skies and snow-capped mountains representing the plateau, and waves and seashells representing the coast.

[0089] Based on this, such as Figure 5 As shown, the above selection of birthday icons from the subgraphs corresponding to constellations in the birthday celebration knowledge graph based on the first and second quantities can be implemented as follows: steps S401-S403: S401. Determine the vehicle's location.

[0090] The vehicle's location refers to the area where the vehicle is currently located. For example, the vehicle's current geographical location can be obtained through an onboard positioning system (such as GPS) to determine the vehicle's location.

[0091] S402. Determine the regional migration coefficient based on the regional cultural differences and / or regional climate differences between the place of residence and the place of origin.

[0092] Among them, the regional transfer coefficient is used to indicate the regional transfer coefficient of the icon's regional style from its place of residence to its place of origin; the regional transfer coefficient is positively correlated with the degree of difference in regional culture and / or regional climate.

[0093] As one possible approach, cultural and climatic difference levels are pre-defined for each region. When the place of residence and the place of origin are not in the same region, the corresponding difference level is determined based on the degree of difference between the two places in regional culture (such as dietary customs, festival traditions, and language characteristics) and / or regional climate (such as temperature zone, dryness / wetness type, and seasonal characteristics). The higher the difference level, the larger the regional transfer coefficient. For example, if the place of residence is in the southern coastal area and the place of origin is in the northern inland area, the differences in regional culture and climate are both significant, resulting in a higher regional transfer coefficient. If the place of residence and the place of origin belong to the same cultural sphere or climate zone, the differences are smaller, resulting in a lower regional transfer coefficient. When the place of residence and the place of origin are in the same region, the regional transfer coefficient is zero.

[0094] S403. Based on the first quantity, the second quantity, the place of residence, the place of origin, and the regional transfer coefficient, select the birthday icon from the subgraph corresponding to the constellation in the birthday knowledge graph.

[0095] As one possible approach, the integration ratio of the permanent residence style and the home location style in the icon is determined based on the regional transfer coefficient. The higher the regional transfer coefficient, the higher the proportion of the home location's regional icon and the lower the proportion of the permanent residence's regional icon. Based on this, and considering the regional characteristics of both the permanent residence and the home location, a corresponding number of permanent residence regional icons and home location regional icons are selected from the sub-maps, and then merged with a first number of non-constellation-related icons and a second number of constellation-related icons to form the final birthday celebration icon.

[0096] In some embodiments, S403 may be further implemented as follows: based on the first quantity, the second quantity, and the regional transfer coefficient, determine the third quantity of regional icons corresponding to the place of residence and the fourth quantity of regional icons corresponding to the place of permanent residence; select constellation-related birthday icons from the sub-map based on the first quantity; select regional icons corresponding to the place of residence from the sub-map based on the third quantity; and select regional icons corresponding to the place of permanent residence from the sub-map based on the fourth quantity.

[0097] For example, multiplying the first number by the regional transfer coefficient yields the third number of regional icons corresponding to the place of origin; subtracting the third number from the first number yields the fourth number of regional icons corresponding to the place of residence. The zodiac-related birthday icons corresponding to the second number are unaffected by the regional transfer coefficient, maintaining their strong visual association with the zodiac. The selected zodiac-related birthday icons (the second number), the regional icons corresponding to the place of origin (the third number), and the regional icons corresponding to the place of residence (the fourth number) are merged to obtain the final birthday icon.

[0098] In some embodiments, the image information further includes: wallpaper preference style. Based on this, the above-mentioned generation of birthday greeting text based on birthday elements includes: determining composition rules based on constellations; and generating birthday greeting text based on the composition rules, wallpaper preference style, and birthday elements.

[0099] Composition rules refer to the layout and spatial relationships of various elements during the generation of in-vehicle wallpapers. Different zodiac signs correspond to different composition rules to match their characteristics. For example, fire signs (such as Aries) can correspond to radial compositions, earth signs (such as Taurus) can correspond to symmetrical compositions, air signs (such as Gemini) can correspond to diagonal compositions, and water signs (such as Cancer) can correspond to wraparound compositions.

[0100] As one possible implementation, determining the composition rules based on constellations can be achieved by: the system pre-constructing a mapping table between constellations and composition rules, and then querying the table to determine the composition rules corresponding to the current constellation.

[0101] For example, the image information of passenger Zhao Liu includes: Leo zodiac sign, wallpaper preference style "minimalist illustration style", birthday elements are gold and orange, cartoon sun and cake, "brilliant", and "May you shine as brightly as the sun, happy birthday". The system determines the composition rule as radial composition based on Leo, fills the composition rule, wallpaper preference style and birthday elements into the template, and generates the prompt text: "Generate a minimalist illustration style birthday image, using radial composition, with the sun in the center, and elements such as cake spreading outwards, gold and orange tones, a brilliant atmosphere, and the background reads 'May you shine as brightly as the sun, happy birthday'".

[0115] The memory 701 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), disk storage medium or other magnetic storage device, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but is not limited thereto.

[0116] In one possible implementation, the memory 701 can exist independently of the processor 702. The memory 701 can be connected to the processor 702 via a bus 704 and is used to store instructions or program code. When the processor 702 calls and executes the instructions or program code stored in the memory 701, it can implement the vehicle wallpaper generation method provided in this embodiment.

[0120] This disclosure provides a computer program product containing instructions that, when run on a processor, cause the processor to execute the vehicle wallpaper generation method described in any of the above embodiments.

[0121] This disclosure provides a vehicle including the control device of any of the preceding embodiments; or the computer-readable storage medium of any of the preceding embodiments; or the computer program product of any of the preceding embodiments.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any changes or substitutions within the technical scope disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
