Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a starry sky ambient lighting control method, electronic equipment, and vehicle. Background Technology

[0002] As automobile manufacturing capabilities improve and people's demands for driving comfort increase, sunroofs, as devices for ventilation and providing a wider view, are increasingly valued for their intelligence and visual appeal. Currently, existing starry sky sunroofs use LED lights along the left and right edges of the glass, with light entering from the side and being reflected by ink dots to form star patterns. However, light intensity decreases exponentially with distance, with the center being the furthest from the lights and the darkest. Furthermore, due to the light-blocking effect of the central island structure's crossbeams, the dark areas are more pronounced, forcing the pattern to shrink to the perimeter and failing to evenly cover the entire sunroof. Summary of the Invention

[0029] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0030] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0032] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0033] Current starry sky ambient lighting for sunroofs generally uses a layered structure of "laminated sunroof glass + lower white glass + side-mounted LED beads + reflective ink on the inner surface": LED light enters the white glass from the edge and is reflected by ink dots during propagation, forming a visible "starlight". However, the light intensity decreases exponentially with the light guide distance. The center of the sunroof is furthest from the LED beads and has the lowest brightness. To avoid obvious dark spots, vehicle designers have to force the pattern to shrink outwards, leaving the central area blank, resulting in a monotonous and discontinuous starry sky design.

[0034] Currently, panoramic sunroofs on commercially available sedans and SUVs still use either "left and right light strips" or "densely arranged LEDs on both sides." While increasing the number of LEDs or lengthening the light strips can improve near-field brightness to some extent, the inherent attenuation of side-incident light still results in a significant dark area near the vehicle's centerline. Furthermore, to balance roof rigidity and collision safety, more and more panoramic sunroofs are incorporating a "central island" beam structure. This physical partition further blocks light, exacerbating the central darkness. With the increasing sophistication of vehicle styling and rising user demands for immersive cabin experiences, the traditional "edge lighting, center avoidance" design approach can no longer meet the new requirements for full-width, uniform, and customizable patterns. A new technological path is urgently needed that can overcome brightness gradient limitations, is compatible with central island structures, and is cost-effective.

[0035] To address the aforementioned issues, embodiments of this disclosure provide a method for controlling ambient lighting in a starry sky setting. This method can be applied to vehicles with a central island structure. The method includes: determining a target lighting area and a target lighting mode; adjusting the opening and closing state of a sunshade based on the target lighting area; and controlling the ambient lighting to illuminate based on the target lighting mode when the sunshade is in the target state. This method can optimize the lighting effect of the ambient lighting on the central island structure while establishing a connection between the sunshade and the expected lighting effect, improving the accuracy of controlling the ambient lighting effect and optimizing the user experience.

[0036] See Figure 1 The above is a flowchart of the starry sky ambient lighting control method provided in the embodiments of this application. The method can be implemented in a vehicle, specifically by an electronic device set in or built into the vehicle, such as by a domain controller in the vehicle. The vehicle includes a canopy with a central island structure and multiple sets of light strips set on the canopy. Each set of light strips may include multiple light sources (such as LED light sources). The vehicle may be a fuel vehicle or an electric vehicle, without any special limitation here.

[0037] It should be noted that, unless otherwise specified, the lighting principle of the starry sky ambient light control method provided in this application embodiment is based on using a light source to illuminate a reflective material for reflection. For example, an extremely thin layer of white reflective ink or a PVB / EVA film mixed with reflective powder is printed between the two layers of glass on a vehicle sunroof. A light source (which can be fixed or movable) illuminates from the edge or a fixed point. The light undergoes multiple total internal reflections inside the glass, and is then directionally scattered upon encountering ink particles or reflective powder, forming visible bright spots.

[0038] like Figure 1 As shown, the method in this embodiment may include steps S101-S103, as follows: S101. Determine the target lighting area and target lighting mode.

[0039] The target lighting area refers to the area on the vehicle's sunroof where the user expects to see a bright spot. For vehicle sunroofs with a central island structure, the target lighting area can be divided into the left side area, the right side area, or both sides area (including both sides).

[0040] In some embodiments, the target illuminated area can be determined autonomously by the vehicle system, or it can be determined based on user instructions. The specific process will be described later and will not be elaborated here.

[0041] Target lighting mode refers to the visual reflective effect of visible bright spots on the vehicle's sunroof, such as the patterns or flow patterns formed by the bright spots.

[0042] In some embodiments, the target lighting mode is obtained through a human-machine interface (such as a vehicle display screen). When the user displays the target lighting mode expected by the motor on the vehicle display screen, the system sends the corresponding target lighting mode command to the control unit (domain controller) of the light strip via the vehicle bus (such as CAN / LIN / Ethernet). After receiving the command, the control unit drives the LED module of the light group according to the preset lighting parameters to illuminate the reflective material on the vehicle sunroof. The preset lighting parameters can be determined experimentally and will not be described in detail here.

[0043] S102. Based on the target lighting area, adjust the opening and closing status of the sunshade.

[0044] In some embodiments, a sunshade is installed above the vehicle sunroof. When the sunshade is closed, outside light enters through the sunroof and can easily dilute the lighting effect of the ambient lights in the corresponding area of ​​the sunroof. Therefore, it is necessary to adjust the opening and closing state of the sunshade according to the target lighting area to eliminate the influence of outside light on the lighting effect of the target lighting area.

[0045] In some embodiments, the initial opening and closing state of the sunshade includes a fully open state, a half open state, a fully closed state, or any intermediate state in between.

[0046] S103. When the sunshade is in the target state, control the ambient light to be lit based on the target lighting mode.

[0047] In some embodiments, the target state includes fully open and partially open. When the sunshade is fully open, it completely blocks light entering the vehicle from the awning. When the sunshade is partially open, it partially blocks light entering the vehicle from the awning.

[0048] In some embodiments, the vehicle uses sensors to collect the motor rotation angle of the sunshade in real time, calculates the percentage of sunshade unfolding, and thus determines whether the sunshade is in the target state. For example, if the unfolding percentage is less than 100%, it is determined that the sunshade is fully open and in the "target state".

[0049] In some embodiments, the ambient lighting includes: a light group disposed on the left side of the roof, a light group disposed on the right side of the roof, and a light group disposed on the island structure of the vehicle roof.

[0050] In some embodiments, the light group disposed on the left side of the canopy is used to illuminate the reflective material on the left side of the canopy; the light group disposed on the right side of the canopy is used to illuminate the reflective material on the right side of the canopy; and the light group disposed on the island structure of the vehicle roof is used to illuminate the reflective material on the left side and / or the canopy.

[0051] In some embodiments, a set of lights can be installed on the island structure of the vehicle, and the illumination direction of the lights can be adjusted by changing the direction of the set of lights; or at least one set of lights can be installed on both sides of the island structure, with the light set on the left side of the island structure used to illuminate the reflective material on the left side of the canopy, and the light set on the right side of the island structure used to illuminate the reflective material on the left side of the canopy.

[0052] For example, taking the installation of a set of lights in the central island structure as an example, the light group structure provided in this application embodiment is as follows: Figure 2 As shown, 1 represents the vehicle island structure, 2 and 3 represent the left and right sunroofs respectively, 21 represents the first light group used to illuminate the reflective material on the left sunroof, 31 represents the second light group used to illuminate the reflective material on the right sunroof, and 41 represents the third light group located on the right side of the island structure.

[0053] For example, taking the installation of light groups on both sides of the central island structure as an example, the light group structure provided in this application embodiment is as follows: Figure 3 As shown, 1 represents the vehicle's central island structure, 2 and 3 represent the left and right sunroofs respectively, 21 and 22 represent the first and fourth light groups used to illuminate the reflective material on the left sunroof respectively, and 31 and 32 represent the second and fifth light groups used to illuminate the reflective material on the right sunroof respectively.

[0054] In some embodiments, controlling the lights in different locations to light up in combination can achieve a variety of lighting effects.

[0055] For example, taking three sets of lights as an example, such as Figure 4 The diagram illustrates the combination of eight different light groups. The numbers (①, ②, ③) indicate the lighting sequence of the light groups, and the arrows indicate the direction of illumination. For ease of understanding, the island structure is not shown. Figure 4 As shown in the image.

[0056] The starry sky ambient light control method provided in this application first determines the target lighting area and the target lighting mode. Then, it determines whether the position of the sunshade in the target lighting area meets the conditions for lighting the ambient light and adjusts the position of the sunshade. When the sunshade is in the target open / closed state, it controls the ambient light in the target lighting area to be lit. This method can optimize the lighting effect of the ambient light in the central island structure canopy while establishing a connection between the sunshade and the expected lighting effect, providing accuracy in controlling the lighting effect of the ambient light and improving the user experience.

[0057] The specific implementation of S101 above is described below.

[0058] One possible approach is to determine the target lighting area based on the distribution of users within the cockpit domain.

[0059] In practice, the vehicle system uses an in-vehicle sensor network to identify and determine the actual distribution of passengers in real time. This sensor network includes, but is not limited to, seat pressure sensors, infrared detection modules, visual recognition cameras, or combinations thereof, to determine whether a passenger is located only in one side of the seating area (left or right) or distributed across both sides. If the user is determined to be located only in the left side of the seating area, the target illuminated area is determined to be the left side; if the user is determined to be located only in the right side of the seating area, the target illuminated area is determined to be the right side; and if the user is determined to be located only in both sides of the seating area, the target illuminated area is determined to be both sides.

[0060] Another possible implementation involves determining the target lighting area in response to a first instruction message from the user. The first instruction message indicates the lighting area of ​​the vehicle's ambient lighting.

[0061] In specific implementation, the vehicle system can receive a first instruction message triggered by the user. This first instruction message is used to clearly specify the target area that the vehicle ambient light needs to be illuminated. The first instruction message can be input to the vehicle system through a human-machine interface, voice control command, touch operation, gesture recognition or other preset interaction methods. After the system obtains and parses the first instruction message, it identifies and determines the corresponding target lighting area based on the lighting area indication information contained therein.

[0062] In this way, the vehicle system can flexibly and proactively control the illuminated areas of the ambient lighting according to personal preferences or actual usage needs, thereby enhancing the personalization and interactive experience of the in-vehicle atmosphere.

[0063] like Figure 5 As shown, the above S102 can be implemented as one of the following S102a, S102b, and S102c: S102a. When the target lighting area includes the left side area, control the left side sunshade of the vehicle to open to the target state.

[0064] S102b: When the target illumination area includes the right side area, control the right side sunshade of the vehicle to open to the target state.

[0065] S102c: When the target lighting area includes both sides, control the sunshades on both sides of the vehicle to open to the target state.

[0066] In some embodiments, the vehicle's light strip control unit selectively controls the sunshade based on the target illumination area. When it is determined that passengers are concentrated in the left-side seat area, the target illumination area includes the left-side area, and the system prioritizes actively controlling only the corresponding electric sunshade on the left, switching the left-side sunshade to the target state. When it is determined that passengers are concentrated in the right-side seat area, the target illumination area includes the right-side area, and the system prioritizes actively controlling only the corresponding electric sunshade on the right, switching the right-side sunshade to the target state. When it is determined that passengers are distributed in both seat areas, the target illumination area includes both sides, and the system actively controls both sunshades, switching both sunshades to the target state.

[0067] Through the aforementioned zoned and side-by-side linkage control method, the ambient lighting area is precisely matched with the opening and closing status of the sunshade, ensuring that the lighting area receives the necessary supplementary lighting conditions or internal ambient reflection, thereby improving the user experience of in-vehicle lighting and ambient effects.

[0068] In an scalable implementation, the starry sky ambient lighting control method provided in this application further includes the following process: when a target door of the vehicle is detected to be open, controlling the ambient lights in the same direction as the target door to illuminate. The target door can be any door in the vehicle.

[0069] In some embodiments, the target door is any openable door of the vehicle, including but not limited to the left front door, right front door, left rear door, right rear door, and tailgate.

[0070] In some embodiments, the vehicle system monitors the opening and closing status of the doors in real time, and when it detects that a target door of the vehicle is opened, it immediately triggers the ambient light illumination operation corresponding to the door's orientation. In a specific implementation, the vehicle system continuously collects and identifies the opening events of each door through position sensors, door contact switches, or electronic control units arranged in each door lock mechanism, hinge area, or body controller. When it is determined that a door has switched from a closed state to an open state, the system identifies that door as the target door in this event and reads the door-ambient light mapping relationship pre-stored in the storage medium to determine at least one set of light strip output channels corresponding to the door's installation orientation. Subsequently, the system sends an illumination command to the drive circuit of the corresponding channel through the vehicle local area network (such as CAN or LIN bus) to control the light strip in that direction to illuminate, thereby illuminating the reflective material in the corresponding area to present a preset lighting effect.

[0071] For example, the mapping relationship between vehicle doors and ambient lighting may include: the left-side doors (left front door and left rear door) correspond to the light group installed on the left side of the sunroof; the right-side doors correspond to the light group on the right side of the sunroof.

[0072] Through the above methods, the opening direction of the car door and the area illuminated by the ambient light can be automatically matched during the user's getting in and out of the car, which improves the convenience and sense of ceremony of using the car at night or in low light conditions, and enhances the intelligent level of human-computer interaction of the vehicle.

[0073] In a scalable implementation, such as Figure 6 As shown, the method of this application further includes the following processes S201-S202: S201. Obtain the ambient light intensity inside the vehicle.

[0074] In some embodiments, the ambient light intensity inside the vehicle can be a numerical parameter used to quantify the current lighting conditions inside the vehicle cabin, and its value can reflect the brightness level inside the cabin in real time.

[0075] In some embodiments, the ambient light intensity inside the vehicle can be obtained by collecting light intensity signals from a light-sensitive sensor (such as a photodiode, an ambient light sensor module, or a light detection unit integrated into an in-vehicle camera) located inside the vehicle cabin. For example, the light-sensitive sensor can be located in a position that is not easily obstructed, such as the center console, vehicle roof, or dashboard, to ensure the accuracy and representativeness of the collected results.

[0076] S202. Adjust the background brightness of the vehicle's sunroof based on the ambient light intensity inside the vehicle.

[0077] In some embodiments, the background brightness of the vehicle sunroof can be adjusted by adjusting its light transmittance. Electrochromic or liquid crystal technology can be used to achieve a continuous change in the glass from "transparent" to "dark," which improves comfort while also ensuring privacy and energy conservation.

[0078] In some embodiments, adjusting the background brightness of the vehicle sunroof can also be achieved by adjusting the overall background brightness of the sunroof using micro-LEDs embedded in the glass layer.

[0079] In some embodiments, the background brightness of the sunroof (such as a dimmable glass sunroof or an LED sunroof screen) is dynamically adjusted based on a preset light compensation algorithm according to the ambient light intensity inside the vehicle, so as to reduce its light transmittance or increase the background darkness, thereby effectively suppressing the interference of strong external light on the lighting effect of the starry sky ambient light inside the vehicle, enhancing the brightness contrast between the starry sky ambient light and the external environment, and ensuring that the clarity of the starry sky pattern and the visual immersion are not compromised.

[0080] In some embodiments, the vehicle system periodically and automatically acquires the ambient light intensity inside the vehicle at preset time intervals, and dynamically adjusts the background brightness of the vehicle's sunroof based on the real-time value of the light intensity, thereby achieving adaptive matching between the sunroof brightness and the interior lighting environment. The preset time interval can be set according to the design requirements for the sensitivity of the sunroof background brightness adjustment, and this application does not impose any particular limitation on it. Generally speaking, the shorter the preset time interval, the more frequently the system responds to changes in light intensity, and the higher the sensitivity of the sunroof background brightness adjustment. This allows for timely optimization of the sunroof's visual comfort and atmospheric consistency in scenarios such as when the vehicle enters a tunnel, during nighttime driving, or when there are sudden changes in external light sources, thereby improving the occupant's visual experience and reducing glare interference.

[0081] In an scalable implementation, the starry sky ambient lighting control method provided in this application further includes the following process: based on the target lighting mode, controlling the background brightness of the vehicle's sunroof to perform zoned brightness adjustment.

[0082] In some embodiments, after determining the target lighting mode, the vehicle system further adjusts the brightness of the vehicle's sunroof by partitioning it according to the spatial distribution information of "lit-unlit" carried by the mode. In a specific implementation, the system first parses the target lighting mode to identify the coordinates of the specific area where the ambient lighting will be lit and the corresponding sunroof partition. Then, for the sunroof area identified as the "lit partition," a first brightness adjustment command is generated to drive the background brightness of that partition to adjust to a target brightness value that matches the effect of the ambient lighting, thereby enhancing the visual layering and immersion of the lit area. At the same time, for the remaining sunroof areas not covered by the target lighting mode, a second brightness adjustment command is generated to reduce the background brightness of these areas to a preset dark value or turn them off completely, so as to form a clear contrast between light and dark and avoid reflections or visual interference from non-lit areas.

[0083] By using the aforementioned zoned brightness adjustment control method, a precise one-to-one coupling between the brightness of the panoramic sunroof background and the lighting position of the ambient lights is achieved, which not only highlights the lighting effect of the ambient lights but also reduces the overall vehicle power consumption.

[0084] In some embodiments, the target lighting mode includes at least one of the following: intersection mode, through mode, and graphic mode.

[0085] Among them, the intersection mode indicates that the light path forms intersecting or colliding bright spots during the lighting process; the through mode indicates that the light path transitions from one side of the canopy to the other side; and the graphic mode indicates that the light path forms static or dynamic graphic effects.

[0086] In some embodiments, the target lighting mode can be executed alone, or it can be combined to create richer lighting effects.

[0087] For example, Figure 7 The effects of three convergence modes were demonstrated, with 2 and 3 representing the left and right celestial canopies, respectively. For ease of understanding, the central island structure and lighting units were not shown. Figure 7 As shown in the image.

[0088] For example, Figure 8 The demonstration showcased the effects of three continuous lighting modes, with 2 and 3 representing the left and right sides of the canopy, respectively. For ease of understanding, the central island structure and lighting units were not shown. Figure 8 As shown in the image.

[0089] For example, the following describes several specific embodiments of the lighting effect of the starry sky ambient light provided in this application.

[0090] Specific Implementation Example 1: "Single 8-shaped line" is lit up.

[0091] The bright spot starts from the left rear row, slides along the arc to the center of the roof, then turns to the right front row, forming the first "O" shaped closed loop. It then pulls back to the center from the right front, then swings to the left front, then turns around and runs through the center to the right rear, finally returning to the starting point on the left rear, forming a horizontal "8" shape. The cycle repeats, and a continuous light band can be seen drawing circles on the roof.

[0092] Specific Implementation Example 2: "Double 8-shaped line" is lit up.

[0093] Two light streams start simultaneously, one running in the forward direction of the single figure 8, and the other running in the opposite direction; when the two meet in the center, the brightness increases instantly, like meteors colliding and then continuing on their own, forming an ∞-shaped intersecting light trail, and the entire roof of the car shows an interlaced flowing "∞" symbol, which continues to cycle.

[0094] Specific Implementation Example 3: "First half through + second half convergence" is lit up.

[0095] In the front row of the canopy: the bright spot on the left sweeps at a constant speed to the center, and then to the right, completing a horizontal "left → center → right" flow; in the back row of the canopy: the left and right rear sections rise and fall like breathing lights, fading in and out alternately; the two effects are performed simultaneously, visually making the front row "flow" and the back row "breathe".

[0096] Specific Implementation Example 4: "Single-sided intersection and through-through switching" is activated.

[0097] In the front area of ​​the canopy, lights are turned on sequentially in the order of "left front → middle → right front". Then switch to the rear row, with the left rear side and right rear side lighting up simultaneously, and then turning off simultaneously after "colliding" in the middle.

[0098] Specific Implementation Example 5: Graphic Lighting.

[0099] The patterns of fish, birds, and butterflies formed by bright spots move across the sky according to a preset trajectory. During the movement, the patterns themselves can also change, creating dynamic effects such as flapping wings.

[0100] The starry sky ambient light control method provided in this application is described below through a complete embodiment. The specific process is as follows: Figure 9 As shown.

[0101] S1. Determine the target lighting area and target lighting mode.

[0102] The target illuminated areas include single-sided and double-sided areas.

[0103] S2. Determine whether the sunshade in the target illuminated area is in the target open / closed state.

[0104] If not, proceed to step S3, then proceed to step S4; If so, proceed to step S4.

[0105] S3. Adjust the opening and closing status of the sunshade in the target illuminated area to the target opening and closing status.

[0106] Specifically, when the target lighting area includes the left side, the left side sunshade of the vehicle is opened to the target state; when the target lighting area includes the right side, the right side sunshade of the vehicle is opened to the target state; when the target lighting area includes both sides, the left and right side sunshades of the vehicle are opened to the target state.

[0107] S4. Control the ambient light to illuminate based on the target lighting mode.

[0108] S5. Adjust the background brightness of the vehicle's sunroof based on the ambient light intensity inside the vehicle and the target lighting mode.

[0109] Adjusting the background brightness of the canopy includes adjusting the overall background brightness and the background brightness of specific areas.
