The following will be described in detail respectively.
[0039] Embodiment 1
[0040] Please refer to Figure 1 , Figure 1This application discloses a vehicle 1 with a dimmable panoramic sunroof 11 installed on its roof 10. The dimmable panoramic sunroof 11 is a window installed on the roof of the car, providing aesthetic appeal, safety, and a large area for light and visibility. As a sunroof installed on the roof of the vehicle, it effectively improves air circulation and increases the intake of fresh air. The sunroof also provides a wider field of vision and meets the needs of mobile photography and videography. Types of sunroofs include single sunroofs, segmented openable panoramic sunroofs, segmented non-openable panoramic sunroofs, openable panoramic sunroofs, and non-openable panoramic sunroofs. For example, a segmented openable panoramic sunroof typically consists of two separate sections located at the front and rear of the roof, with openable sections. Dimmable panoramic sunroofs can also be used on the windshield or side windows of a vehicle, enhancing the user experience.
[0041] Please see Figure 2 , Figure 2 This application discloses a vehicle with a dimming panoramic sunroof in its interior, and the vehicle also includes at least one projection device 12. The projection device 12 can project stored images or images transmitted from external devices via wired or wireless means. External devices can include mobile terminals, mobile devices, etc., specifically mobile terminals such as mobile phones, tablets, laptops, or in-vehicle PADs, or devices with shooting or observation functions such as drones or telescopes. Taking connection with a mobile phone as an example, the projection device can refer to a projector, which connects to the mobile phone wirelessly, such as via Bluetooth or Wi-Fi. Images (videos, pictures, etc.) on the mobile phone exist in the form of digital electrical signals (such as encoded MP4 or JPG data). Through a wireless communication protocol, the mobile phone "wirelessly transmits" the image signals, which are then received by the projector. The projector receives the signals and uses a decoding chip to analyze them, restoring them to pixel data. After analyzing the received data, adjustments are made, such as optimizing the image, so that the projector can clearly project the data onto the panoramic sunroof. In this application embodiment, images can be projected onto the dimming panoramic sunroof using the projection device, that is, using existing dimming glass as a projection screen. The projection device can be installed on the B-pillar of the vehicle, the headrest of the seat, the dashboard of the vehicle, or the roof of the vehicle, in areas that can directly project onto the dimming sunroof.
[0042] Optionally, the projection device 12 is configured to respond to a projection command and control the projection device 12 to project an image onto the dimming screen 11, wherein when the projection device 12 is in projection mode, the dimming screen 11 is in a non-transparent state.
[0043] In this embodiment, the dimming canopy 11 primarily achieves its dimming function through technologies such as polymer-dispersed liquid crystal (PDLC), electrochromic (EC), and dye-liquid crystal (DLC). These technologies control light transmittance through different principles, allowing the dimming canopy 11 to switch between transparent and opaque states. For example, a dimming canopy 11 using polymer-dispersed liquid crystal technology involves adding a liquid crystal film between two layers of glass. When a voltage is applied, the film forms an electric field, causing the liquid crystal molecules to align neatly, allowing light to pass through smoothly, and the dimming canopy 11 becomes transparent. When the voltage disappears, the liquid crystal molecules return to their disordered arrangement, and light scatters as it passes through, turning the canopy opaque (milky white) or foggy. PDLC dimming canopies typically only offer two transmittance settings: fully transparent and fully foggy, making a gradual transition effect impossible. EC and DLC dimming canopies offer continuously adjustable transmittance within a certain range. Generally, the light transmittance in a non-transparent state is lower than that in a transparent state. For example, when the dimming screen receives a projection command or detects that the projection device is dimming the screen, it switches to a non-transparent state. That is, if the dimming screen is transparent, it needs to switch from transparent to non-transparent. In other words, it ensures that the dimming screen is non-transparent when the projection device is in projection mode. In the non-transparent state, the light transmittance of the dimming screen is minimized. At this time, the dimming screen effectively blocks external light interference, creating a quiet, comfortable, and highly immersive viewing environment, making passengers feel as if they are in a private cinema. By realizing the linkage between the working states of the projection device and the dimming screen, external light interference is reduced, creating a cinema-like viewing atmosphere for users, improving the intelligence of the cabin, and enhancing the immersive experience for passengers. If the dimming canopy is made of glass, it can be understood that the dimming canopy includes the canopy glass and the corresponding sunshade screen. When the projection device performs the work of projecting onto the dimming canopy, i.e. the canopy glass, the sunshade screen is controlled to close to reduce light transmittance.
[0044] It's worth noting that the projection command isn't necessarily triggered by the user; it can also be automatically triggered by the vehicle system based on various intelligent scenario analyses. For example, when the vehicle is parked and the system detects that passengers have been stationary for an extended period, it can preliminarily determine that the user is resting or waiting. The system can then automatically determine that the passenger may have entertainment needs, triggering the projection command. The projection device then operates, displaying rich movie content, music visualizations, or fun game interfaces on the dimming screen to help passengers pass the time. Similarly, during long journeys, if the vehicle system detects that rear passengers have fastened their seatbelts and are in a comfortable sitting position for a period of time, it can automatically activate the projection function to play movies suitable for long journeys, alleviating passenger fatigue. Alternatively, the user can generate the projection command, such as by operating the vehicle's infotainment system (PAD) and sending the command via the CAN bus to the microcontroller unit (MCU) connected to the PAD. The MCU then controls the projection device and / or the dimming screen to enter the corresponding operating state based on the projection command.
[0045] In summary, the projection device 12 projects onto the dimming screen while simultaneously controlling the dimming screen 11 to be in a non-transparent state, thus achieving the linkage between intelligent projection and dimming. This enhances the intelligence of the smart cabin, adds a sense of technology, and improves the user's driving experience.
[0046] Optionally, the vehicle also includes a control device connected to both the dimming screen and the projection device, the control device being used to control the operating status of the dimming screen and the projection device. In other words, the vehicle's dimming screen control system also includes a control device connected to both the dimming screen and the projection device.
[0047] Please see Figure 5 and Figure 6 , Figure 5 and Figure 6 These are two control systems for vehicle dimming canopies disclosed in the embodiments of this application. In this system, the dimming canopy and the projection device can be connected to the control device. Figure 5 What is publicly disclosed is that the dimming canopy and the projection device are connected via different controllers. Figure 6 The publicly disclosed method involves connecting the dimming canopy and the projection device via a single controller.
[0048] In this embodiment, the vehicle also includes a control device, which can be a controller, such as an MCU, an Electronic Control Unit (ECU), or other controllers with control functions. The control device is connected to the dimming screen, allowing adjustment of its operating state. It is also connected to a projection device, allowing adjustment of its operating state. The control device connected to both the dimming screen and the projection device can be the same or different devices. Indicatively, a single controller is connected to both the dimming screen and the projection device simultaneously. The controller receives instructions, performs logical judgments, and then synchronously controls both the dimming screen and the projection device. For example, when a user activates the screen theater function via the vehicle's PAD, or when the vehicle detects parking or the driver's or rear seat being reclined, it can be preliminarily determined that the user needs to rest. The controller then controls the dimming screen to gradually reduce its transmittance to the minimum, projecting a preset image onto the screen. When the controllers connected to the dimming canopy and the projection device are different, the controller connected to the dimming canopy is responsible for adjusting the state of the dimming canopy, such as light transmittance and zone color change, while the controller connected to the projection device controls and adjusts the projection parameters, such as brightness, focal length, and content switching. The two can also communicate in real time via CAN bus, so as to suit the need for independent adjustment of the canopy and the projection, and also meet the needs of complex scene adaptation.
[0049] Optionally, the vehicle includes a seat configured to be linked to a projection device, wherein the seat is in an adjustment state when the projection device is in projection mode.
[0050] In this embodiment, the vehicle (e.g., a vehicle controller) monitors the working status of the projection device in real time. When the projection device is detected to be activated, i.e., the projection mode is turned on, the seat adjustment command is triggered, realizing the linkage between the seat and the projection device. At this time, the seat adjustment command can be automatically triggered according to the type of projection content, the distribution of passengers in the cabin, and the user's preset preferences, achieving the dual goals of adapting the projection image and adjusting the seat to optimize the riding experience. The seat may include the driver's seat or the rear seat, and can also be determined by identifying the seat corresponding to the viewing user's sitting position, such as through the vehicle monitoring system. For example, a rear passenger triggers the activation of the panoramic projection through the rear entertainment screen. If the vehicle is equipped with the corresponding function, the passenger can watch the movie by clicking on the panoramic projection or start the preset mode through the in-vehicle APP. The projection device starts and projects the image onto the panoramic screen, while the dimming panoramic screen switches to the lowest transmittance, non-transparent state. At this time, the seat can be controlled to be in the adjustment state, and the seat back angle can be adjusted to 45°-50°. If, during the seat adjustment process, the passenger presses the manual seat adjustment button or triggers the "emergency braking" signal, the seat immediately stops adjusting, prioritizing the passenger's manual operation to ensure safety. Users can also adjust the seat to the target position to ensure that the user is in the best position to view the image on the dimming screen when sitting in the seat adjusted to the target position.
[0051] Optionally, the projection device is adapted to connect to a mobile terminal, and the projection device is used to receive images sent by the mobile terminal.
[0052] In this embodiment, the linkage between the mobile terminal and the projection device enables content reception and storage. The mobile terminal includes in-vehicle tablets, drones, mobile phones, tablets, and in-vehicle telescopes. The projection device supports both wireless and wired connections. The mobile terminal supports wireless connection methods such as Wi-Fi, Bluetooth, and NFC near-field communication. Users can search for the projection device name using the "wireless projection" function on their mobile terminal. After successful pairing, images, such as videos or pictures from the mobile terminal, can be pushed in real time. If NFC connection is used, simply placing the mobile terminal near the NFC sensing area of the projection device completes pairing and automatically triggers projection, suitable for quick-start scenarios. The projection device can also be equipped with a corresponding interface, such as a Type-C interface, allowing users to directly connect the mobile terminal and the projection device via a Type-C data cable for low-latency image transmission.
[0053] Optionally, the vehicle may also include a drone, which is configured to capture images in response to a user’s shooting command and send the captured images to a projection device connected to the drone or a mobile terminal connected to the drone.
[0054] In this embodiment, the vehicle is equipped with a drone, which can take off with a single click to explore the route and intelligently capture the beauty of sunrise. The drone can be directly or indirectly connected to a projection device to combine its real-time positioning and environmental adaptation capabilities to present diverse views of the surrounding environment. When a user commands the drone to start shooting or projecting, it can fly according to the automated mode set in the cabin, shooting in fixed shapes such as circles or squares, or following a route planned by the user. When the drone is directly connected to the projection device, the drone uses a built-in wireless communication module, such as a Wi-Fi module, and the projection device is equipped with a corresponding Wi-Fi receiver module; the two are pre-paired. For example, after the user sends a shooting command via in-vehicle voice commands (such as "shoot and project with drone" or "shoot with drone remote control"), the drone completes the shooting and transmits the raw image data directly to the projection device via Wi-Fi. After receiving the image data, the projection device projects the image onto the dimming screen. Simultaneously, the dimming screen can be switched to a non-transparent state, and the seat adjustment can be synchronized accordingly. After receiving the image, the projection device can automatically verify its integrity. If there are no errors, it triggers an "image adaptation" process, including cropping the image ratio according to the size of the dimming canopy, adapting the drone-captured landscape video to the curved aspect ratio of the dimming canopy. The drone can also connect to mobile terminals, such as in-vehicle tablets or control panels (phones, tablets, etc.), to transmit captured data to the mobile terminal. Users can then view the drone's flight status and captured images on their mobile devices. Simultaneously, users can transmit images from their mobile terminals to the projection device for projection. In other words, the drone can transmit data in real-time to the in-vehicle screen via positioning sensors. When the user confirms that the in-vehicle screen image is projected onto the canopy, the dimming canopy switches to the drone's footage, satisfying the user's immersive experience and simulating the feeling of free flight over the sky and sea.
[0055] Optionally, the drone also features a power management and return-to-base mechanism. The drone monitors its power level in real time, and when the power level falls below a threshold, it performs a return-to-base operation. For example, during flight, the drone sends power data, such as "current power 35%, remaining flight time 12 minutes," to a connected device (projection device / mobile terminal) every 3 seconds. The power percentage and return-to-base countdown can be displayed in real time on the vehicle's PAD.
[0056] Optionally, the drone can also control the quality of transmitted video based on its remaining battery power. For example, if the drone has 50% or more of battery power remaining, it prioritizes high-quality video transmission, such as using 4K resolution. If the remaining battery power is between 20% and 50%, it automatically switches to 1080P resolution to reduce power consumption. If the battery power is less than 20%, it immediately pauses the shooting mission, sends a "low battery warning" to the vehicle's system or the user's mobile device, and initiates an autonomous return-to-charge procedure. A dedicated charging compartment for the drone is pre-installed in the vehicle's trunk or roof, allowing the drone to automatically dock with the charging contacts upon return.
[0057] Optionally, the vehicle may also include a vehicle-mounted telescope, which is configured to observe the environment in response to a user's observation command and send the captured images to a projection device connected to the telescope or a mobile terminal connected to the telescope.
[0058] In this embodiment, the vehicle is equipped with a car-mounted telescope, which can be used to view the starry sky or gaze into the distance. The telescope can be installed in the middle of the roof rack. A customized mounting interface is provided in the middle of the roof rack, and the telescope is fixed with a quick-release bracket, allowing for tilt adjustment. The bracket has a built-in shock-absorbing module, including a silicone buffer pad and a spring shock absorber, to prevent lens damage from bumps. Alternatively, the telescope can be installed along the upper edge of the rear side window. An embedded mounting slot is provided near the B-pillar or C-pillar along the upper edge of the rear side window, allowing the telescope to be folded and stored inside the interior window trim panel. The telescope supports both wired and wireless communication. It has a built-in Type-C data interface, allowing direct connection to a projection device or vehicle infotainment system via a shielded data cable provided in the vehicle, suitable for stargazing, capturing detailed distant scenes, and other scenarios. Optionally, the data cable has a built-in automatic cable retraction module, which extends and retracts synchronously when the telescope's angle is adjusted, preventing tangling. The vehicle-mounted telescope can also have built-in Bluetooth and / or Wi-Fi modules, enabling wireless connection with projection devices and mobile terminals such as smartphones or tablets. Automatic pairing is supported during wireless connection. Users can open the corresponding function on their mobile terminal, such as a vehicle-mounted observation app, click to connect the telescope, and it will automatically search for nearby devices and complete pairing. Users can then view the environmental images from the vehicle-mounted telescope's perspective in real time via their mobile terminals. Specifically, when the vehicle-mounted telescope observes and captures images based on user commands, the captured images are sent to the projection device connected to the telescope. The projection device can then project the images onto a dimming screen for display, or it can send the captured images to the mobile terminal connected to the telescope, allowing users to view the environmental images from the vehicle-mounted telescope's perspective in real time via their mobile terminals.
[0059] Optionally, the vehicle-mounted telescope includes a distance perception module that obtains the distance of the observation target in real time and automatically focuses according to the distance perception module. The automatic focusing includes adjusting the focal length of the vehicle-mounted telescope by distance, as well as clarity, etc.
[0060] Optionally, the projection device includes a ranging unit and / or an image clarity analysis module. After the projection device is started, the actual distance from the dimming skylight glass is measured in real time through a ranging unit such as a sensor. Then, the projection chip drives the focusing mechanism according to a pre-calibrated focal length distance mapping table to quickly move the optical focal plane to the corresponding position. The image clarity analysis module calculates and evaluates according to the color, contrast, edge sharpness, etc. of the projection image based on real-time data; if blurriness is detected, the control loop automatically fine-tunes the focusing light source until the clarity meets the pre-set threshold.
[0061] Optionally, the dimming skylight imaging mode includes at least a first imaging mode and a second imaging mode different from the first imaging mode. The first imaging mode is a three-dimensional (3D) imaging mode. Among them, when the dimming skylight is in the 3D imaging mode, the dimming skylight is projected by at least three projection devices.
[0062] In the embodiment of the present application, there are two imaging modes of the dimming skylight. The first imaging mode is the 3D imaging mode, which projects parallax images from different perspectives through at least 3 projection devices to achieve the naked-eye 3D effect. In this case, it is necessary to ensure the synchronization of the 3 projection devices. At the same time, the high-contrast display characteristics of the dimming skylight can also be combined to improve the display effect of the naked-eye 3D. Generally, it is arranged hidden at the left and right B pillars, as well as the back of the seat, etc. As long as the 3 projection points achieve the 3D effect. The dimming skylight also includes a second imaging mode different from the first imaging mode, which can be realized by projecting the dimming skylight through 1-2 projection devices. Taking 1 projection device as an example, by projecting through 1 projection device, 2D (Two Dimensions) projection display of the image can be achieved. Users can select the corresponding imaging mode according to the scene requirements.
[0063] Through the vehicle described above, the dimming skylight of the vehicle can be connected to in-vehicle devices to achieve linkage. The in-vehicle devices include a car machine PAD, seats, projectors, etc. The dimming skylight of the vehicle can be connected to out-of-vehicle devices, such as devices with shooting or image transmission functions such as mobile phones, tablets, drones, telescopes, etc., which can enrich the display content projected on the dimming skylight by the projection device and improve the fun and richness of users using the cockpit.
[0064] Embodiment 2
[0065] Please refer to Figure 3 , Figure 3This is a flowchart illustrating a control method for a vehicle dimming sunroof disclosed in an embodiment of this application. Figure 3 The described method can be applied to the control system or display device of an electronic device or a vehicle dimming sunroof. The control system of the electronic device or vehicle dimming sunroof can be a standalone device or integrated into a processing device; this application does not limit this. The above-described control method for a vehicle dimming sunroof is applied to the vehicle disclosed in Embodiment 1 of this application. This vehicle includes: Figure 3 As shown, a dimming roof and at least one projection device are included, with the dimming roof adapted to be installed on the roof of a vehicle. The control method for this vehicle dimming roof may include the following operations:
[0066] 301: In response to a projection command, control at least one projection device to project an image onto a dimming pylon, wherein when the projection device is in projection mode, the dimming pylon is in a non-transparent state.
[0067] In this embodiment, the projection device is configured to respond to a projection command and project an image onto the dimming screen. Specifically, when the projection device is in its working state, a preset image can be projected onto the dimming screen. Simultaneously, when the projection device is in projection mode, the dimming screen is in a non-transparent state. By controlling the dimming screen in conjunction with the projection device's working state—meaning that whenever the projection device is detected to be activated or entering projection mode—the controller switches the dimming screen to a non-transparent state. This ensures that the screen's light transmittance is reduced to a non-transparent range suitable for projection requirements, preventing external light interference with the projected image. This enhances the contrast and clarity of the projected image, creating a cinema-like viewing atmosphere for the user.
[0068] Optionally, the dimming canopy imaging mode includes at least a first imaging mode and a second imaging mode different from the first imaging mode.
[0069] In this embodiment, the dimming canopy has two imaging modes. The first imaging mode is a 3D imaging mode, which uses at least three projection devices to project parallax images from different perspectives to achieve a naked-eye 3D effect. In this case, it is necessary to ensure the synchronization of the three projection devices. Simultaneously, the high contrast display characteristics of the dimming canopy can be combined to improve the naked-eye 3D display effect. These are typically placed in the left and right B-pillars for concealment, as well as on the back of seats, etc., as long as three projection points achieve a 3D effect. The dimming canopy also includes a second imaging mode different from the first imaging mode, which can be achieved by projecting onto the dimming canopy using one or two projection devices. Taking one projection device as an example, projection using one device can achieve a two-dimensional (2D) projection display of the image. Users can select the corresponding imaging mode according to their needs.
[0070] Optionally, the projection device is used to receive and project images sent by a mobile terminal connected to the projection device.
[0071] In this embodiment, the linkage between the mobile terminal and the projection device enables content reception and storage. The mobile terminal includes in-vehicle tablets, drones, mobile phones, tablets, and in-vehicle telescopes. The projection device supports both wireless and wired connections. The mobile terminal supports wireless connection methods such as Wi-Fi, Bluetooth, and NFC near-field communication. Users can search for the projection device name using the "wireless projection" function on their mobile terminal. After successful pairing, images, such as videos or pictures from the mobile terminal, can be pushed in real time. If NFC connection is used, simply placing the mobile terminal near the NFC sensing area of the projection device completes pairing and automatically triggers projection, suitable for quick-start scenarios. The projection device can also be equipped with a corresponding interface, such as a Type-C interface, allowing users to directly connect the mobile terminal and the projection device via a Type-C data cable for low-latency image transmission.
[0072] In this embodiment, the dynamic dimming and projection display functions of the canopy can work together, and can also be combined with the linkage control of external vehicle devices and in-vehicle smart terminals (such as smartphones and in-vehicle infotainment systems). The following examples illustrate this using a human-machine interface, a drone, and an in-vehicle telescope interacting with the projection device. Please refer to... Figure 4 , Figure 4 This is a flowchart illustrating another control method for a vehicle dimming sunroof disclosed in an embodiment of this application. The control method includes:
[0073] S01: Human-Machine Interface. The human-machine interface is activated to obtain user commands and execute the next operation. In other words, the human-machine interface provides an intuitive operating interface, allowing users to easily control and operate various vehicle systems and functions, and can acquire and recognize voice commands and touchscreen operations.
[0074] S02: MCU Controller. The MCU controller is responsible for coordinating and managing various functions and operations of the vehicle. The MCU controller communicates with the human-machine interface (HMI) via the CAN bus. When the user operates on the HMI, the user commands are transmitted to the MCU controller of the automotive electronic system via the CAN bus.
[0075] S03: Determine whether to activate the intelligent panoramic cinema function. The vehicle system is equipped with an intelligent panoramic cinema function, which enables coordinated control of the dimming panoramic screen and the projection device. After receiving the instruction, the user needs to confirm whether to activate the panoramic cinema function. If the user activates the panoramic cinema function, execute S04; otherwise, do not execute, and the operation ends.
[0076] S04: Dimming Dome Opens (No Transparency). When a user command is received to open the dome theater, the dimming dome is switched to a non-transparent state to ensure projection clarity. If the dimming dome is currently transparent, it will automatically switch to a non-transparent state (lower light transmittance), after which S05 can be executed.
[0077] S05: User uploads video or image. After receiving the projection instruction, the user first needs to select the projection content, usually an image or video. To prevent the user from selecting the wrong content, S06 needs to be executed after the user selects the projection content.
[0078] S06: Determine whether the selected view is confirmed. After the projection content is determined, to avoid user errors and protect user privacy, the user needs to confirm whether to select the current photo or video for projection. If the selected view is not to be projected, execute S06, and the user needs to re-upload; if it is the view the user wants to project, execute S07.
[0079] S07: Turn on the hidden projector. After the user confirms the image to be projected, the hidden projector enters working mode. The projector may also be non-hidden. To ensure the projected content is correct, S08 can be executed after turning on the hidden projector.
[0080] S08: Determine if screen mirroring is desired. After the projector is ready, the user needs to confirm again whether to start screen mirroring. If screen mirroring continues, proceed to the next step S09; if screen mirroring is refused, the process ends.
[0081] S09: Automatic screen mirroring from user's mobile phone or vehicle infotainment system. After entering the screen mirroring mode, the system can connect to the user's mobile phone or vehicle infotainment system to simultaneously mirror the displayed content onto the dimming screen, achieving synchronized display.
[0082] The projection device and dimming dome can also be linked with drones to enhance the sense of technology, specifically including:
[0083] S10: Positioning sensor. The drone uses its own positioning sensor to report its current location, allowing users to monitor the flight destination and direction at any time.
[0084] S11: Determine whether to activate the drone galaxy projection function. The drone galaxy projection function involves using a drone to capture images and then transmitting and projecting those images. For example, a drone can capture images of the starry sky and transmit the information, thus completing the drone galaxy projection. This process requires user permission.
[0085] S12: Real-time UAV positioning and environmental monitoring. UAVs rely on their own positioning sensors and temperature and wind speed sensors to collect and identify the overall conditions of the current external environment.
[0086] S13: Determine whether to start the drone. When the user selects the drone galaxy projection function and can choose whether to start the drone according to their own preferences, they can then decide whether to enter the working mode. If the drone is started, proceed to S14.
[0087] S14: Drone Position Tracking and Path Planning. In operational mode, the drone can perform data acquisition, data processing and analysis, and route planning.
[0088] S15: Drone-captured photos and data transmission. The drone will simultaneously transmit real-time photos of the surrounding environment to the vehicle's main screen, allowing users to understand the outdoor conditions.
[0089] S16: In-vehicle infotainment screen display. Users can view photos and videos transmitted by the drone in real time on the main screen inside the vehicle.
[0090] S17: Determine if the drone's battery level is less than 1 / 10. If the drone's battery level drops below 1 / 10 during flight, it must return to the hangar for charging. If the battery level is sufficient, it can continue filming and complete the real-time projection of the dimming celestial screen. When the drone's battery level is not less than 1 / 10, proceed to step S07 above and follow the subsequent steps. When the drone's battery level is less than 1 / 10, proceed to step S18.
[0091] S18: The drone stops filming and returns to the hangar. When the drone's battery level drops below the protection level during a filming mission, it must return to the hangar to recharge.
[0092] S19: Determine whether to activate the Sky Dome Vision function. The high curvature of the skylight glass itself provides a Sky Dome Vision experience, creating a 3D effect when projected onto a fixed angle and number of in-vehicle projectors. When the Sky Dome Vision function is activated, execute S20.
[0093] S20: Turn on the vehicle-mounted telescope and projector. This provides a buffer for the projected image.
[0094] S21: Determine whether to activate the telescope function. The user needs to confirm whether to turn on the telescope function. If activated, proceed to S22; otherwise, the process ends.
[0095] S22: Projection control and implementation optimization. The projector automatically adjusts itself based on the distance to the object and the desired sharpness to ensure a clear and visible projection onto the diaphragm glass.
[0096] S23: Environmental safety monitoring and battery level indicator. The projector itself can monitor whether the surrounding environment is safe and whether the battery level is sufficient.
[0097] S24: Determine whether to disable the projection indicator function. Users can decide whether to disable the projection function based on their own needs. If projection is required, S25 can be executed; otherwise, the process ends.
[0098] S25: User selects 2D / 3D projection. The user chooses the projection method according to their preference and sets the projected image to 2D / 3D effect.
[0099] The content that can be interacted with by drones and vehicle-mounted telescopes, along with the projection device and the dimming canopy, can also be linked with the dimming canopy to ensure that the dimming canopy is in a non-transparent state during the projection phase.
[0100] The control method for the vehicle dimming canopy described above also includes the content disclosed in Embodiment 1, that is, the projection device, the working mode of the dimming canopy, and the linkage with the drone and vehicle-mounted telescope described in Embodiment 2 can all be supplemented based on the content disclosed in Embodiment 1, and will not be described in detail here.
[0101] Example 3
[0102] Please see Figure 5 and Figure 6 , Figure 5 and Figure 6 This is a schematic diagram of the control systems for two types of vehicle dimming sunroofs disclosed in the embodiments of this application. Please refer to [link / reference]. Figure 5 and Figure 6 , Figure 5 and Figure 6 These are two control systems for vehicle dimming canopies disclosed in the embodiments of this application. In this system, the dimming canopy and the projection device can be connected to the control device. Figure 5 What is publicly disclosed is that the dimming canopy and the projection device are connected via different controllers. Figure 6 The disclosed method involves connecting the dimming canopy and the projection device via a single controller. It is applied to vehicles. The system includes:
[0103] A dimming awning, the dimming awning being adapted to be installed on the roof of a vehicle;
[0104] At least one projection device is configured to respond to a projection command by projecting an image onto a dimming pylon, wherein the dimming pylon is in a non-transparent state when the projection device is in projection mode.
[0105] In the embodiments of the present application, a projection device projects onto the dimming sky screen, and at the same time, the dimming sky screen is联动controlled to be in a non-transparent state, realizing the联动of intelligent projection and dimming, improving the intelligence of the intelligent cabin and adding a sense of technology. At the same time, the driving experience of users can be improved. The system can also provide a romantic starry sky experience for the passengers in the vehicle, and can also switch different projection themes according to user needs, such as festival decorations, natural landscapes, etc., greatly enhancing the diversity and趣味性of in-vehicle entertainment.
[0106] The control device can be a controller, such as an MCU, an Electronic Control Unit (ECU), and other controllers with control functions. By connecting the control device to the dimming sky screen, the working state of the dimming sky screen can be adjusted by control. By connecting the control device to the projection device, the working state of the projection device can be adjusted by control. The control device connected to the dimming sky screen and the projection device can be the same or different control devices. Schematically, a single controller is simultaneously connected to the dimming sky screen and the projection device. The controller receives instructions, makes logical judgments, and then synchronously controls the dimming sky screen and the projection device. Exemplarily, the user operates through the in-vehicle PAD to start the sky screen cinema function, or the vehicle detects parking and the front driver's seat or the rear seat is reclined. At this time, it can be preliminarily determined that the user needs to rest at this time. The controller controls the dimming sky screen to gradually decrease to the lowest light transmittance and projects a preset image onto the dimming sky screen. When the controllers connected to the dimming sky screen and the projection device are different, the controller connected to the dimming sky screen is responsible for adjusting the state of the dimming sky screen, such as light transmittance and zonal color change, and the controller connected to the projection device controls and adjusts projection parameters, such as brightness, focal length, and content switching. The two can also communicate in real time through the CAN bus, so that it can be suitable for the need for independent adjustment of the sky screen and projection, and can also meet the requirements of complex scenario adaptation.
[0107] The control system of the vehicle dimming sky screen described above can be used to implement the steps of the control method of the vehicle dimming sky screen disclosed in Embodiment II of the present application, and specifically can also include the content of the case disclosed in Embodiment I, which will not be described in detail here.
