Description

Technical Field

[0001] This invention relates to the field of vehicle control, specifically to a dynamic starry sky top control method and related equipment. Background Technology

[0002] A starry sky ceiling is a decorative system created by integrating fiber optic lights, LED lights, and other light sources into the vehicle ceiling, along with translucent materials and starry sky simulation technology. It can accurately reproduce celestial landscapes such as stars, nebulae, and the Milky Way in the night sky. Not only can the brightness, flashing frequency, and even constellation arrangement of the lights be adjusted, but it can also create an immersive night sky atmosphere, combining decorative and atmospheric functions, allowing people in the car to experience the tranquility and brilliance of the starry sky without having to go outside.

[0003] In the automotive interior design field, starry sky headliners have been widely used to enhance the luxury and comfort of the cabin. Currently, most mainstream starry sky headliners are static designs, consisting of a fixed number and arrangement of luminous points on the car's roof to create a starry-sky-like visual effect. However, this traditional static starry sky headliner has several limitations. First, the patterns are limited, often pre-set at the factory and cannot be changed. Prolonged use can lead to visual fatigue for passengers, and the novelty wears off after multiple rides, failing to continuously satisfy their desire for a unique and novel experience. Second, it lacks flexibility and adaptability, unable to adapt to different scenarios, times, or locations. During daytime driving, the static starry sky headliner effect is not noticeable; at night, it cannot display dynamic effects to match different scenarios such as highway driving, city commuting, and leisure travel. Therefore, current static starry sky headliners cannot present a variety of image changes, leading to user boredom and a poor driving experience over time. Summary of the Invention

[0020] Starlight headliners, used to enhance the luxury and comfort of the cabin, have been widely adopted. Currently, most mainstream starlight headliners are static designs, consisting of a fixed number and arrangement of illuminated dots on the car's roof to create a starry sky-like visual effect. However, this traditional static starlight headliner has several limitations. First, the patterns are limited, often pre-set at the factory and cannot be changed. Prolonged use can lead to visual fatigue for passengers, and the novelty wears off after multiple rides, failing to continuously satisfy their desire for a unique and novel experience. Second, they lack flexibility and adaptability, unable to adapt to different scenarios, times, or locations. During daytime driving, the static starlight headliner effect is not noticeable; at night, it cannot display dynamic effects to match different scenarios such as highway driving, city commuting, and leisure travel. Therefore, current static starlight headliner technology cannot present a variety of image changes, leading to user boredom and a poor driving experience over time.

[0021] Based on this, the main objective of this application is to provide a dynamic starry sky roof control method and related equipment, which aims to adaptively change the starry sky roof pattern according to the vehicle driving environment, making the vehicle interior richer and providing users with a better visual experience.

[0022] This application provides a dynamic starry sky ceiling control method and related equipment, relating to the field of vehicle control. The invention uses luminescent fibers with a controller to sew ceiling patterns and constructs a control and interaction system capable of sensing various information. The invention selects high-brightness, low-energy-consumption, flexible, and bend-resistant luminescent fibers to ensure clear and aesthetically pleasing pattern illumination, without affecting the ceiling's texture or installation during sewing, and adapting to vehicle vibrations and minor ceiling deformations. Through automated sewing equipment, the sewing path is precisely controlled according to a pre-set program, sewing the luminescent fibers onto the ceiling to form specific patterns, such as simulating star shapes and distribution while considering brightness differences. The controller is key to realizing dynamic pattern changes; it connects to the vehicle's CSC central control system. A light sensor monitors ambient light to determine day and night, a GPS module obtains the vehicle's location, and a clock system provides time information. This information is transmitted to the CSC. The CSC selects a suitable pattern from a rich pattern library according to a preset program and sends a signal to the luminescent fiber controller. The controller precisely adjusts parameters such as the luminescence time, brightness, and flashing frequency of each fiber to achieve pattern changes. Specific embodiments are described below, starting with a dynamic starry sky ceiling control method from this application.

[0023] Figure 1 This is a flowchart of a dynamic starry sky ceiling control method provided in an embodiment of this application. Please refer to it. Figure 1 The dynamic starry sky top control method provided in this application embodiment may include, but is not limited to, steps S100 to S500.

[0024] Step S100: Obtain the vehicle's external environmental parameters, including images, temperature, and location.

[0025] Optionally, using the vehicle shell as a dividing standard, the vehicle is divided into two spaces: an external environment and an internal environment. The external environment parameters include, but are not limited to, external images, external temperature, external brightness, and vehicle position. Further, as an optional implementation, the acquisition of these external environment parameters is achieved through a multi-sensor fusion acquisition scheme: a high-definition camera mounted above the windshield captures real-time image information of the road ahead, traffic participants, traffic signs, and weather conditions; high-precision temperature sensors installed in the front grille, rearview mirrors, and rear of the vehicle collect ambient air temperature data; and combined with a combined positioning technology of the onboard global navigation satellite system and inertial measurement unit, the vehicle's latitude, longitude, altitude, and driving trajectory are dynamically acquired. These three types of parameters are synchronously transmitted to the central processing unit via the onboard controller local area network bus, providing real-time and reliable environmental perception input for functions such as autonomous driving decision-making, intelligent temperature control, and path planning.

[0026] Step S200: Identify the current driving scenario of the vehicle based on the external environment parameters of the vehicle.

[0027] It should be noted that the current driving scenario of the vehicle refers to the specific scenario of the vehicle's external environment. For example, the specific scenario of the vehicle's external environment may include, but is not limited to, the seaside, mountains, urban scenic spots, etc. In addition to identifying the specific driving scenario of the vehicle, it can also identify which season the vehicle is in and what time it is. The present invention can identify the season, time and specific scenario of the vehicle based on the vehicle's external environmental parameters, and can accurately determine the overall external environment of the vehicle.

[0028] Step S300: Control the starry sky top to display the image according to the current driving scene of the vehicle.

[0029] Those skilled in the art will understand that the image displayed on the starry sky roof is dynamically adapted to the vehicle's current driving scenario. In some embodiments, the vehicle determines the current driving scenario in real time based on multi-source sensor fusion data, and dynamically adapts the theme of the starry sky roof image through the in-vehicle intelligent control system. When driving on urban roads, the starry sky roof mainly displays a low-brightness, dispersed star pattern to avoid strong light interfering with the driver's vision. In high-speed cruising scenarios, it switches to a uniformly distributed, soft starlight, combined with a slowly flowing dynamic effect, to alleviate fatigue during long-distance driving. When driving in the suburbs or scenic areas, a high-definition panoramic mode is activated to enhance the immersive visual experience. In addition, the system can also automatically adjust the brightness of the starry sky roof according to the ambient light intensity to ensure visual comfort and driving safety in different driving scenarios.

[0030] Step S400: Obtain the vehicle's internal environment parameters, including the vehicle's in-vehicle music.

[0031] It is easy to understand that the vehicle's interior environmental parameters are obtained through sensors inside the cabin, which may include, but are not limited to, cabin temperature, brightness, and in-car music. Further, as an optional implementation, the in-car music can be obtained from the vehicle's player to infer the user's current mood, thereby better controlling the starry sky roof to serve the user.

[0032] Step S500: Control the rate of change of the starry sky top image according to the vehicle's internal environmental parameters.

[0033] Furthermore, after selecting the starry sky image based on the vehicle's external environment, the speed of image change needs to be adjusted according to the vehicle's interior environment to prevent users from getting bored by viewing the same image repeatedly. Variations in the image can provide novelty. As an optional implementation, the speed of image change can be controlled based on the rhythm of the in-car music playback. The faster the music, the faster the image changes; conversely, if the current music is a soothing track, the image should change slowly and gradually.

[0034] This invention significantly enhances the user experience by enriching the visual experience for passengers inside the vehicle. It changes dynamic visuals in real time according to different scenarios, preventing visual fatigue and making each journey unique. For example, during long trips, passengers can enjoy different styles of dynamic starry sky ceiling patterns as the itinerary changes, adding to the enjoyment of the journey. In terms of personalization, it satisfies consumers' pursuit of personalized car interiors. Consumers can customize their vehicle interiors by interacting with the vehicle system to set pattern changing rules or selecting from the pattern library, making the interior truly unique. From the perspective of enhancing product competitiveness, it creates a unique selling point for intelligent car cockpit interiors. Compared to traditional static starry sky ceilings, dynamic starry sky ceilings are more innovative and technologically advanced, attracting more potential consumers and becoming a significant differentiating competitive advantage, increasing product added value and market share. From an aesthetic perspective, when not illuminated, the ceiling is simple and unified, better integrating various interior styles; when illuminated, the dynamic patterns enhance the cabin's luxury and technological atmosphere, creating a high-quality driving and riding space.

[0035] Furthermore, step S300 may include, but is not limited to, steps S310 to S340.

[0036] Step S310: Match the vehicle's current driving scene with the preset image theme of the starry sky roof.

[0037] Those skilled in the art will understand that the vehicle's current driving scenario can be any of the following: rural, coastal, urban, mountainous, or canyonous. The current driving scenario theme is determined by identifying its features, and then a preset image from the corresponding theme is played on the starry sky top. In some embodiments, when features such as water, sand, and coconut trees are identified, it is confirmed as a coastal theme, and a coastal theme image is played on the starry sky top. When features such as tall buildings, roads, and traffic are identified, it is confirmed as an urban theme, and an urban theme image is played on the starry sky top. When features such as mountains, rivers, and forests are identified, it is confirmed as a mountain theme, and a mountain theme image is played on the starry sky top. This invention can accurately identify the theme of the current driving scenario and select the corresponding theme image from the starry sky top, providing users with a good visual experience.

[0038] As an optional embodiment, the present invention can also optimize the image presented on the starry sky roof in conjunction with a specific date. For example, if the day is a holiday, the system can retrieve and play images related to the holiday theme to allow users to experience a good holiday atmosphere.

[0039] Step S320: Determine the planar image to be played based on the image theme of the starry sky top.

[0040] Optionally, the present invention presets multiple themes in the starry sky roof, each theme containing multiple corresponding theme images. The preset image themes of the starry sky roof include, but are not limited to, rural landscapes, seaside scenes, urban landscapes, mountain landscapes, and canyons. For each of these themes, corresponding theme images are selected. Further, as an optional implementation, the theme image with the most votes can be selected through user voting, or the theme image can be customized according to the user's personal preferences. Each theme image has both daytime and nighttime presentation formats, providing users with different experiences during daytime and nighttime driving, greatly improving user comfort.

[0041] Step S330: Calculate the coordinates of the light-emitting fibers that need to emit light from the starry sky top based on the planar image.

[0042] Furthermore, after determining the theme of the starry sky roof playback, the next planar image to be played is determined according to the playback order of the planar images in the theme. The coordinates of the light-emitting fibers that need to emit light in the starry sky roof are calculated based on the next planar image to be played, so as to control the starry sky roof to present a planar image of the current driving scene. In some embodiments, a mapping relationship is established between the pixel coordinate system of the planar image and the physical coordinate system of the starry sky roof, clarifying the scaling factor and origin correspondence rules between the two. Pixel coordinates of the emitting area in the planar image are extracted using an image recognition algorithm, effective emitting pixels are selected and noise interference is eliminated, and the conversion from pixel coordinates to the two-dimensional plane of the starry sky roof is completed based on a preset scaling factor. Combining the installation curvature of the starry sky roof and the spatial arrangement parameters of the light-emitting fibers, a spatial positioning algorithm is used to convert the planar image coordinates into the actual coordinates of the light-emitting fibers. This invention maps the planar image coordinates to the coordinates of the light-emitting fibers, accurately presenting the desired image and improving the user's driving experience. Further, as an optional implementation method, refer to... Figure 4 The luminescent fiber comprises a surface insulating coating 410, an active coating 420, an inner electrode 430, and an outer electrode 440. The inner electrode 430 is covered by the outer electrode 440, the outer electrode 440 is covered by the active coating 420, and the active coating 420 is covered by the surface insulating coating 410, forming a luminescent fiber. The specifications of the luminescent fiber are: diameter 0.3mm and 0.5mm; the thicker the diameter, the higher the brightness. Display effect: It can achieve a breathing effect; a single line cannot flow, but a flowing effect can be achieved by electrically controlling multiple lines to light up one by one. Manufacturing process: Embroidery—abrasion resistance 5000 times; Fabric—abrasion resistance 8000 times. It can be used in non-high-frequency touch areas. Lifespan: 3000 hours for constant illumination. Color (reference). Figure 6 Currently, 10 colors are available. A layer of fabric (black and translucent) is added to the embroidery surface, making the embroidery invisible when not illuminated. Regarding the luminescent material, novel flexible LED materials can be explored to replace luminescent fibers, achieving similar dynamic pattern effects through proper layout and control. For sensors, in addition to light sensors, GPS modules, and clock systems, accelerometers and gyroscopes can also be considered to sense the vehicle's driving status, using this as the basis for pattern changes. However, regardless of the alternative chosen, the key issues of precisely controlling pattern changes and effectively integrating with other vehicle systems must be addressed to achieve the invention's objectives of improving user experience and enabling personalized customization.

[0043] Step S340: Light up the light-emitting fiber according to the coordinates of the light-emitting fiber that needs to emit light.

[0044] Furthermore, after calculating the coordinates of the light-emitting fibers, it is necessary to control the light emission of the fibers according to their coordinates. In some embodiments, the target coordinates of the light-emitting fibers are verified for accuracy, invalid coordinates with deviations exceeding a threshold are eliminated, and the valid coordinate signals are converted into drive commands by the vehicle-mounted intelligent control module. These commands are then transmitted to the starry sky roof drive circuit via the CAN bus. The drive circuit activates the corresponding light-emitting fiber circuit according to the commands, while simultaneously monitoring the fiber brightness and circuit stability in real time, and dynamically calibrating the current output to ensure that the light emission state meets preset requirements. In some embodiments, the present invention selects high-brightness, low-energy-consumption, flexible, and bend-resistant light-emitting fibers to ensure that the pattern is clearly and beautifully illuminated, does not affect the texture and installation of the roof during sewing, and adapts to vehicle vibration and minor deformation of the roof. In some embodiments, refer to Figure 5 This invention utilizes automated sewing equipment to precisely control the sewing path according to a pre-set program, sewing luminescent fibers onto the ceiling to form specific patterns, such as simulating star shapes and distribution while considering brightness differences. The green portions of the warp threads are luminescent fibers, and the blue portions of the weft threads are conductive fibers. The connection points between the luminescent and conductive fibers are electroluminescent units 510. In some embodiments, the controller of this invention is key to realizing dynamic pattern changes; it is connected to the vehicle's CSC central control system. A light sensor monitors ambient light to determine day / night, a GPS module obtains the vehicle's location, and a clock system provides time information. This information is transmitted to the CSC, which, according to a pre-set program, selects a suitable pattern from a rich pattern library and sends a signal to the luminescent fiber controller. The controller precisely adjusts parameters such as the luminescence time, brightness, and flashing frequency of each fiber to achieve pattern changes. For example, during the day when there is ample light, the controller adjusts the luminescent fibers to display bright and simple patterns, such as flowing lines or geometric shapes, adding a sense of technology; at night, when driving at high speeds, it simulates shooting stars streaking across the night sky, enhancing driving excitement in sync with the driving rhythm; during urban commutes, it presents a soft, slowly flowing nebula pattern to relieve stress. The patterns change according to different seasons and locations, such as spring flower elements, starry sky and wave patterns by the sea, to create an immersive experience, thereby producing the aforementioned beneficial effects such as improving user experience, personalization, product competitiveness, safety and aesthetics.

[0045] Furthermore, step S330 may include, but is not limited to, step S331.

[0046] Step S331: Infinitely adjust the color temperature and brightness of the luminescent fiber according to the interior temperature and exterior brightness.

[0047] In simple terms, stepless adjustment is a control method that allows for continuous and smooth parameter adjustment without fixed gears. Its core feature is abandoning the traditional discrete adjustment logic of "gear-based" adjustments. Through electronic control, mechanical transmission, or signal modulation technologies, it achieves continuous changes in target parameters within a set range, with no breaks and smooth transitions in the adjustment process. In the automotive electronics field (such as starry sky headlight control, air conditioning systems, and lighting adjustments), stepless adjustment is widely used. For example, the stepless brightness adjustment of a starry sky headlight can receive signals from an ambient light sensor via an onboard controller, dynamically changing the driving current of the light-emitting fibers to achieve a continuous and gradual change in brightness from 0 to the maximum threshold, avoiding the visual abruptness of gear switching. Similarly, stepless adjustment of air conditioning fan speed and seat heating temperature allows users to precisely match comfort parameters according to their needs, improving the user experience. As an optional implementation, the cabin temperature is collected in real time by an in-vehicle temperature sensor, and the brightness data is captured by an external ambient light sensor. The color temperature and brightness parameters are matched according to a preset mapping model by an intelligent algorithm—adapting to cool tones and medium to low brightness at high temperatures, and switching to warm tones and moderately increasing brightness at low temperatures. At the same time, dynamic fine-tuning of external brightness is combined to avoid glare. Finally, a continuously changing drive signal is output through a PWM linear drive circuit to achieve stepless smooth adjustment of the color temperature and brightness of the luminescent fiber, which not only ensures visual comfort, but also takes into account energy-saving requirements through precise light control.

[0048] Figure 3 A starry sky ceiling example of the method in this application is given, combined with Figure 3 The invention provides a detailed introduction and explanation of the solutions in its embodiments, including examples of starry sky ceilings and specific application scenarios. For instance... Figure 3 As shown, the control method includes the following steps: Step 1: The light sensor detects that the ambient light is gradually dimming, the temperature sensor detects that the current temperature is 30°C, the clock system indicates that it is summer evening, and the GPS module determines that the vehicle is approaching the sea.

[0049] Step 2: The current driving scene of the vehicle is identified as: a seaside at dusk in summer.

[0050] Step 3: The controller selects a pattern from the pattern library that matches the summer evening seaside scene. The luminous fibers start working, and twinkling stars first appear on the ceiling. As the vehicle approaches the seaside, the dynamic pattern of waves intertwines with the stars, as if a real seaside starry sky scene is presented to the passengers.

[0051] Step 4: If soothing music is playing in the car at this time, the music system will transmit the music characteristic information to the controller.

[0052] Step 5: The rhythm of the starry sky ceiling pattern changes becomes slower and softer, echoing the melody of the music and creating a comfortable and relaxing atmosphere for passengers.
