[0035] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] In order to facilitate understanding of the method provided in the embodiment of the present application, the sunroof assembly of the vehicle involved in the embodiment of the present application is first introduced.

[0041] The vehicle sunroof assembly provided in the embodiments of the present application may include a sunroof and a sunshade device. The sunroof may be a fixed device mounted on the top of the vehicle, i.e., a closed sunroof. Alternatively, the sunroof may be a movable device mounted on the top of the vehicle, i.e., an openable sunroof, such as a built-in sunroof or a sliding sunroof. Furthermore, the sunroof may be a panoramic sunroof or a segmented sunroof. For example, the sunroof may be a closed panoramic sunroof. The embodiments of the present application do not specifically limit the type of sunroof.

[0042] The sunshade device may be a sunshade curtain or a sun visor. The sunshade device may be installed on the roof of the vehicle. In some embodiments, the sunshade device is movably installed below the sunroof. For example, the sunshade device may be slidably installed below the sunroof. Of course, there are many other specific structural forms and installation methods for the sunshade device, which will not be described in detail in the embodiments of this application.

[0043] The vehicle sunroof assembly may further include a lighting device capable of illuminating the sunroof. The lighting device may extend in the longitudinal direction of the sunroof, which corresponds to the longitudinal direction of the vehicle. The lighting device may include a plurality of light-emitting elements, which are sequentially arranged in the longitudinal direction of the sunroof.

[0044] In some embodiments, the light emitting element may be a light emitting diode (LED). It is understood that there are many types of light emitting elements, and the present invention does not specifically limit them in this embodiment.

[0045] In some embodiments, the plurality of light-emitting elements may be distributed on the skylight in a certain order. For example, the plurality of light-emitting elements may be arranged at equal intervals on the skylight.

[0046] In some embodiments, the plurality of light-emitting elements can be divided into multiple groups, each group comprising at least two light-emitting elements, and each group of light-emitting elements can be distributed across the skylight using a structure such as a light strip. For example, the light-emitting elements of each group can be arranged equidistantly on the light strip. The multiple light strips can be arranged sequentially along the longitudinal direction of the skylight.

[0047] In practice, the vehicle's domain controller can control the movement of the sunshade according to user needs. When the sunshade is retracted, the sunroof is exposed. When the sunshade is deployed, it blocks the sunroof. When the sunroof is blocked, a sunshade effect is achieved. When the sunroof is exposed, the vehicle can illuminate the area of ​​the sunroof not blocked by the sunshade, creating a starry sky effect. Of course, the sunroof can also have other functions when exposed, which will not be discussed in detail here.

[0048] In the embodiments of the present application, the starry sky effect refers to an ambiance that simulates the night sky. This starry sky effect is achieved by covering the surface of the sunroof within the vehicle with fluorescent or reflective materials in the shape of stars or the moon, and then disposing multiple light-emitting elements on this surface. When the multiple light-emitting elements are illuminated, the light emitted by the light-emitting elements hits the fluorescent or reflective materials on the sunroof, and the area of ​​the sunroof not blocked by the blocking device presents a "starry sky" effect.

[0049] Furthermore, by adjusting the color, brightness, and number of illuminated elements, users can create different starry sky effects to create a unique atmosphere. At night, users can control the vehicle's sunroof to enter starry sky mode, experiencing a variety of unique starry sky effects and relaxing. When on a date, users can control the vehicle's sunroof to enter starry sky mode, creating a unique, luxurious halo inside the vehicle, adding a touch of tenderness and romance.

[0050] FIG1 is a flow chart of a method for controlling a sunroof of a vehicle provided in an embodiment of the present application. The method is applied to a vehicle, such as an electronic device on a vehicle. The electronic device may be a domain controller of the vehicle. Optionally, the vehicle may be a sedan, an off-road vehicle, a sport utility vehicle (SUV), or a commercial vehicle. Of course, the vehicle may also be other types of vehicles, and the vehicle type is not specifically limited here. As shown in FIG1 , the method may include:

[0051] Step S1100: receiving an instruction to set the skylight to starry sky mode.

[0052] In an embodiment of the present application, the instruction for placing the sunroof in starry sky mode may include one of a first instruction and a second instruction. The first instruction may be an instruction for instructing: gradually lighting up the light-emitting device of the sunroof while the sunshade device is slowly retracted. The second instruction may be an instruction for instructing: gradually extinguishing the light-emitting device of the sunroof while the sunshade device is slowly extended. The content indicated by the first instruction (i.e., gradually lighting up the light-emitting device of the sunroof while the sunshade device is slowly retracted) and the content indicated by the second instruction (i.e., gradually extinguishing the light-emitting device of the sunroof while the sunshade device is slowly extended) can be interchangeable, and are not limited here.

[0053] Under the first command, when the sunshade device is slowly retracted, the area of ​​the sunroof blocked by the sunshade device gradually decreases, and the area of ​​the non-blocked area not blocked by the sunshade device gradually increases. Under the second command, when the sunshade device is slowly deployed, the area of ​​the sunroof blocked by the sunshade device gradually increases, and the area of ​​the non-blocked area not blocked by the sunshade device gradually decreases.

[0054] In some embodiments, whether the instruction for placing the sunroof in starry sky mode is the first instruction or the second instruction can be determined based on a user-input instruction. If the user-input instruction is "enter starry sky mode" and "slowly retract the sunshade," the vehicle can determine that the instruction for placing the sunroof in starry sky mode is the first instruction. If the user-input instruction is "enter starry sky mode" and "slowly extend the sunshade," the vehicle can determine that the instruction for placing the sunroof in starry sky mode is the second instruction.

[0055] In some embodiments, the vehicle is equipped with a receiving device for receiving user input commands. This receiving device can be a touchscreen central control screen of an onboard computer, a voice control system for receiving external voice, an image acquisition system for performing facial recognition, or a fingerprint recognition system for collecting user fingerprints. Of course, other types of receiving devices are also possible, and this embodiment of the present application does not impose any excessive limitations.

[0056] The receiving device can be used to receive various types of commands input by the user. The command generally refers to any form of signal input that can cause the vehicle's sunroof to enter the starry sky mode. In some embodiments, the command can be any of the following: a touch command, a voice command, a gesture command, an expression command, and a fingerprint command.

[0057] For example, if a user wants to turn the sunroof of a vehicle into starry sky mode, they can touch the central control screen on the vehicle's computer to set the "starry sky mode" function option displayed on the central control screen to "on". Alternatively, if a user wants to turn the sunroof of a vehicle into starry sky mode, they can speak or shout to the voice control system to input the command "enter starry sky mode".

[0058] For example, when the user wants to slowly retract the sunshade, the user can operate a button to retract the sunshade or to unfold the sunshade. Alternatively, the user can input a command of "retract the sunshade" or "unfold the sunshade" through the voice control system.

[0059] After receiving the instruction input by the user, the receiving device of the vehicle can send the instruction to the domain controller of the vehicle. The domain controller of the vehicle can then determine whether the instruction to put the sunroof in the starry sky mode is the first instruction or the second instruction based on the instruction.

[0060] Step S1200: According to the instruction to put the skylight in the starry sky mode, the light-emitting area of ​​the skylight and the area of ​​the shielding area of ​​the skylight blocked by the sunshade device are controlled.

[0061] The luminous area of ​​the skylight is the area of ​​the luminous region of the skylight. The luminous region of the skylight can be the entire area not blocked by the sunshade device, or a portion of the area. The difference between the luminous area of ​​the skylight and the area of ​​the non-blocked area of ​​the skylight not blocked by the sunshade device is less than a preset value. That is, the luminous area of ​​the skylight can increase as the area of ​​the non-blocked area of ​​the skylight increases, and decrease as the area of ​​the non-blocked area decreases.

[0062] In some embodiments, the difference between the luminous area of ​​the sunroof and the area of ​​the non-blocked area of ​​the sunroof not blocked by the sunshade device refers to the difference between the area of ​​the luminous area of ​​the sunroof and the area of ​​the non-blocked area of ​​the sunshade device along the longitudinal direction of the vehicle. This difference needs to be less than a preset difference.

[0063] In the embodiments of the present application, the movement of the sunshade device and the lighting (or extinguishing) of the light-emitting device may be out of sync. For example, the speed at which the sunshade device is retracted is faster than the speed at which the light-emitting device is illuminated. At this time, as the sunshade device is retracted, the light-emitting device in a small portion of the non-blocking area of ​​the skylight is not illuminated. For another example, the speed at which the sunshade device is deployed is slower than the speed at which the light-emitting device is extinguished. At this time, as the sunshade device is deployed, the light-emitting device in a small portion of the blocked area of ​​the skylight, that is, blocked by the sunshade device, is not extinguished.

[0064] In some embodiments, the closer the aforementioned preset difference value is to 0, the more synchronized the lighting of the light-emitting device is with the retraction of the sunshade device, or the more synchronized the extinguishing of the light-emitting device is with the deployment of the sunshade device. In this case, the shorter the time the user waits for the skylight to display the starry sky effect, the better the user experience. The preset difference value can be set based on the specific control requirements of the skylight and is not specifically limited here.

[0065] In some embodiments, the ratio of the luminous area of ​​the skylight to the area of ​​the non-blocked area can satisfy a preset ratio range, such that the difference between the luminous area and the area of ​​the non-blocked area is less than a preset difference. The closer the preset ratio value is to 1, the closer the preset difference is to 0. The preset ratio range can be set based on the specific control requirements of the skylight and is not specifically limited here.

[0066] After the vehicle provided by the embodiment of the present application receives an instruction to put the sunroof in starry sky mode, it can control the luminous area of ​​the sunroof and the area of ​​the blocked area of ​​the sunroof blocked by the sunshade device according to the instruction, so that the difference between the luminous area of ​​the sunroof and the area of ​​the non-blocked area of ​​the sunroof not blocked by the sunshade device is less than a preset value. In other words, the method provided by the embodiment of the present application can make the sunroof of the vehicle illuminate to present a starry sky effect during the movement of the sunshade device. Compared with the method in which the starry sky effect can only be presented after the sunshade device moves to a position where it completely does not block the starry sky sunroof, on the one hand, it effectively shortens the time required for the sunroof to present the starry sky effect, thereby reducing the time the user spends waiting for the sunroof to present the starry sky effect, and effectively improving the user experience; on the other hand, it can enable the sunroof to present the starry sky effect in a zoned manner, thereby improving the flexibility of the starry sky effect presentation of the sunroof.

[0067] It is understandable that the sunroof needs to be in a completely closed state before it enters the starry sky mode to form a starry sky effect.

[0068] In an embodiment of the present application, if the sunroof is a movable device installed on the roof of the vehicle, the vehicle can detect the state of the sunroof before the sunroof enters the starry sky mode to create a starry sky effect. If the vehicle detects that the sunroof is in the open state, it can control the sunroof to be in the fully closed state.

[0069] In the case where the sunroof is a fixed device installed on the roof of the vehicle, such as a fixed panoramic sunroof, since the sunroof is always in a completely closed state, the vehicle does not need to detect the switch status of the sunroof before controlling the sunroof to enter the starry sky mode.

[0070] In an embodiment of the present application, the sunroof and the light-emitting elements provided on the sunroof may be blocked by the sunshade device. If the sunroof and the light-emitting elements are completely blocked by the sunshade device, the sunroof cannot create a starry sky effect in the vehicle. Therefore, before the sunroof is illuminated by the light-emitting elements to form a starry sky effect, the vehicle can obtain the state of the sunshade device in advance. The state of the sunshade device may include one of a blocked state and an unblocked state. The unblocked state refers to a completely unblocked state. The blocked state may include one of a partially blocked state and a completely blocked state.

[0071] In some embodiments, the vehicle can obtain the status of the sunshade device in response to a command to set the sunroof to starry sky mode. For example, when the vehicle's receiving device receives a user input command to set the sunroof to starry sky mode, the vehicle's domain controller can read the relative position relationship between the sunshade device and the sunroof to obtain the status of the sunshade device.

[0072] In some embodiments, after receiving a command to set the sunroof to starry sky mode via a receiving device, the vehicle may first determine the state of the sunroof. If the vehicle determines that the sunroof is fully closed, it may read the relative position between the sunshade device and the sunroof to obtain the state of the sunshade device.

[0073] In some embodiments, the instruction for setting the sunroof in the starry sky mode is the first instruction. In this case, as shown in FIG2 , step S1200 may include steps S2100 to S2200 .

[0074] Step S2100: Control the movement of the sunshade device according to the first instruction to reduce the area of ​​the sunroof blocked by the sunshade device.

[0075] In an embodiment of the present application, the vehicle can control the movement of the sunshade device according to the first instruction to control the folding of the sunshade device, so that the area of ​​the blocked area of ​​the sunroof is reduced, thereby increasing the area of ​​the non-blocked area of ​​the sunroof.

[0076] Step S2200, according to the first instruction, control the light-emitting elements in the non-blocking area of ​​the skylight to be in a lit state, and the light-emitting elements in the blocking area of ​​the skylight to be in an extinguished state, so as to control the light-emitting area of ​​the skylight.

[0077] In an embodiment of the present application, the vehicle can synchronously light up the light-emitting elements in the non-blocked area as the sunshade device moves, or can light up the light-emitting elements in the non-blocked area when the difference between the area of ​​the unblocked area of ​​the sunroof that is not blocked by the sunshade device and the area of ​​the current light-emitting area of ​​the sunroof (i.e., the light-emitting area) is a preset value.

[0078] The vehicle may be provided with a drive device for moving the sunshade device. The drive device may be provided with a sensor. The sensor may be used to monitor the position of the sunshade device in real time. Optionally, the sensor may be a Hall effect element.

[0079] In one example, when movement of the sunshade device is detected, the drive device can send a Hall effect signal to the vehicle's domain controller. In response, the domain controller can receive the Hall effect signal. Based on the Hall effect signal, the domain controller can then determine the movement distance S1 of the sunshade device and synchronously illuminate the light-emitting elements within a first region of the sunroof. This first region is the area of ​​the sunroof that is visible from the start to the end of the sunshade's movement. The length of this first region is the movement distance S1, and this length is parallel to the longitudinal direction of the sunroof.

[0080] Assuming that a plurality of light emitting elements are evenly distributed on the skylight, and the distance between adjacent light emitting elements is S2, in this case, the number N of light emitting elements lit during the movement of the sunshade device can satisfy: N=S1 / S2.

[0081] In the embodiment of the present application, the light emitting elements located in the shielding area are always in an off state, thereby reducing unnecessary energy waste.

[0082] As mentioned above, the blocking state of the sunshade device can include a partial blocking state and a full blocking state, that is, the sunshade device can be in a partial blocking state or a full blocking state. When the sunshade device is in the full blocking state, the sunshade device will completely block the skylight.

[0083] In an embodiment of the present application, when the sunshade device is in a partially obstructed state, the unobstructed area of ​​the skylight not obstructed by the sunshade device may include: an original unobstructed area and a new unobstructed area. The original unobstructed area is the unobstructed area before the sunshade device is moved. The new unobstructed area is the unobstructed area added during the movement of the sunshade device.

[0084] At this time, the process of lighting up the light-emitting elements in the non-blocking area may include lighting up the light-emitting elements in the original non-blocking area and lighting up the light-emitting elements in the new non-blocking area. The new non-blocking area is the non-blocking area added as the sunshade device is retracted.

[0085] In some embodiments, among the multiple light-emitting elements, the light-emitting elements located in the new non-blocking area can be illuminated synchronously when the sunshade device moves to reduce the size of the blocked area. That is, when the vehicle controls the sunshade device to move to increase the size of the non-blocking area according to the first command, the light-emitting elements in the new non-blocking area can be illuminated synchronously. This can further reduce the time users wait for the sunroof to create a starry sky effect, thereby improving the user experience.

[0086] In some embodiments, the light-emitting elements in the original non-blocking area may be pre-lit, and then the sunshade device may be controlled to move and the light-emitting elements in the new non-blocking area may be lit synchronously.

[0087] In one example, when movement of the sunshade device is detected, the drive device can send a Hall effect signal to the vehicle's domain controller. The vehicle's domain controller then receives the Hall effect signal and, based on it, determines the position of the sunshade device and the distance S3 of the unobstructed area on the sunroof not blocked by the sunshade device. The controller then simultaneously illuminates the light-emitting elements within a second area. The length of this second area is the distance S3 of the unobstructed area, and the length is oriented along the longitudinal direction of the sunroof.

[0088] Assume that a plurality of light emitting elements are evenly distributed on the skylight, and the distance between adjacent light emitting elements is S2. In this case, the number N1 of light emitting elements pre-lit before the sunshade device moves satisfies N1 = S3 / S2.

[0089] After the vehicle's domain controller illuminates the light-emitting elements in the unobstructed area of ​​the sunroof, it controls the movement of the sunshade and obtains the sunshade's travel distance S4. Simultaneously, the sunshade also illuminates the light-emitting elements in the third area. At this point, the number of illuminated light-emitting elements, N2, equals S4 / S2. The third area is the area of ​​the sunroof that is visible from the start to the end of the sunshade's movement. The length of this third area is the travel distance S4, and its length is parallel to the longitudinal direction of the sunroof.

[0090] As can be seen from the above description, in the embodiment of the present application, a light-emitting device extending in the longitudinal direction of the sunroof is provided on the top of the vehicle for illuminating the sunroof. The light-emitting device includes a plurality of light-emitting elements. Furthermore, when the vehicle controls the movement of the sunshade device to increase the area of ​​the non-blocked area of ​​the sunroof not blocked by the sunshade device, the light-emitting elements not blocked by the sunshade device can also be illuminated, thereby creating a starry sky effect for the sunroof by lighting the light-emitting elements in a segmented and regional manner. Furthermore, when the sunshade device is controlled to move to increase the area of ​​the non-blocked area of ​​the sunshade device, the light-emitting elements located in the blocked area are extinguished, thereby reducing energy waste.

[0091] In some embodiments, the instruction for setting the skylight in the starry sky mode is the second instruction. In this case, as shown in FIG3 , step S1200 may further include steps S3100 to S3200 .

[0092] Step S3100: Control the sunshade device to move according to the second instruction to increase the area of ​​the sunroof blocked by the sunshade device.

[0093] In an embodiment of the present application, the vehicle can control the movement of the sunshade device according to the second instruction to control the expansion of the sunshade device, so that the area of ​​the unblocked area of ​​the sunroof is reduced, thereby increasing the area of ​​the blocked area of ​​the sunroof.

[0094] Step S3200, according to the second instruction, control multiple light-emitting elements so that the light-emitting elements located in the non-blocking area of ​​the skylight are in a lit state and the light-emitting elements located in the blocking area of ​​the skylight are in an extinguished state, so as to control the light-emitting area of ​​the skylight.

[0095] In an embodiment of the present application, the vehicle can synchronously extinguish the light-emitting elements in the blocked area as the sunshade device moves, or can extinguish the light-emitting elements in the blocked area when the difference between the area of ​​the unblocked area of ​​the sunroof and the area of ​​the current light-emitting area of ​​the sunroof is a preset value.

[0096] In some embodiments, when the sunshade device is in a partially blocked state, the blocked area of ​​the skylight by the sunshade device may include an original blocked area and a new blocked area. The original blocked area is the blocked area before the sunshade device is moved. The new blocked area is the blocked area added during the movement of the sunshade device.

[0097] At this time, the process of extinguishing the light emitting elements in the shielding area may include extinguishing the light emitting elements in the original shielding area and extinguishing the light emitting elements in the new shielding area, which is the shielding area added as the sunshade device is deployed.

[0098] In some embodiments, among the multiple light-emitting elements, the light-emitting elements in the newly blocked area can be synchronously illuminated when the sunshade device moves to increase the area of ​​the blocked area. In other words, when the vehicle controls the sunshade device to move to increase the area of ​​the blocked area according to the second instruction, the light-emitting elements in the newly blocked area can be synchronously extinguished. This can further reduce the time it takes for the user to wait for the sunroof to form a starry sky effect, improving the user experience and reducing energy waste.

[0099] In some embodiments, the light-emitting elements in the original shielding area may be extinguished in advance, and then the sunshade device may be controlled to move, and the light-emitting elements in the new shielding area may be extinguished synchronously.

[0100] The method for determining the number of light-emitting elements that are extinguished before the sunshade device moves and the number of light-emitting elements that are extinguished during the movement can refer to the method for determining the number of lit light-emitting elements in the embodiment of the present application, and will not be described in detail here.

[0101] In some embodiments, when the sunshade device is in a completely unblocked state, the sunshade device will completely expose the skylight. At this time, all light-emitting elements on the skylight are in a lighted state.

[0102] As can be seen from the above description, when the vehicle controls the movement of the sunshade to increase the area of ​​the sunroof blocked by the sunshade, the light-emitting elements blocked by the sunshade are extinguished, while the light-emitting elements in the unblocked area remain illuminated. In other words, by extinguishing the light-emitting elements in a zoned and segmented manner, the sunroof can be made to present a starry sky effect. Furthermore, this method facilitates user control, allowing the user to display the starry sky effect in the desired area of ​​the sunroof.

[0103] In some embodiments, the sunroof control method provided in the embodiments of the present application may further include step S4100.

[0104] Step S4100: During the process of controlling the movement of the sunshade device, if a third instruction for instructing the sunshade device to stop moving is received, the sunshade device is controlled to stop moving and the current state of the light-emitting device is maintained.

[0105] The third instruction generally refers to any form of signal input that can control the sunshade device to stop moving. In some embodiments, the third instruction can be any of the following forms of instructions: a touch instruction, a voice instruction, a gesture instruction, an expression instruction, and a fingerprint instruction.

[0106] After the vehicle's sunroof enters starry sky mode, the vehicle can synchronously light up the light-emitting elements not blocked by the sunshade as the sunshade moves, so that the sunroof can present a starry sky effect in a zoned and segmented manner. If at a certain moment, the user wants to experience the starry sky effect in a part of the area, a third command can be issued during the movement of the sunshade. After receiving the third command, the vehicle can control the sunshade to stop moving, while keeping the already lit light-emitting elements in the lit state, to ensure that the vehicle's sunroof can present a starry sky effect in a zoned and segmented manner, thereby meeting the different needs of users.

[0107] In some embodiments, as shown in FIG4 , the method for controlling the sunroof of a vehicle provided in the embodiment of the present application may further include step S1300 .

[0108] Step S1300: in response to the instruction to exit the starry sky mode, control the light emitting device to be in an off state.

[0109] In an embodiment of the present application, the instruction to exit the starry sky mode may include any of the following instructions: an instruction to open the sunroof; an instruction to open the car door; and an instruction to close the starry sky mode.

[0110] In some embodiments, the command to exit Starry Sky Mode can be user input. For example, the vehicle may be equipped with a receiving device for receiving the command. The receiving device may be a receiving device for receiving the first command and the second command. The command to "exit Starry Sky Mode" generally refers to any form of signal input that can cause the vehicle to exit Starry Sky Mode.

[0111] In some embodiments, the "exit starry sky mode" command can be any of the following: a touch command, a voice command, a gesture command, an emoji command, a fingerprint command, etc. For example, to exit the vehicle's sunroof from starry sky mode, the user can touch the central control screen on the vehicle's onboard computer to set the "starry sky mode" function option displayed on the central control screen to "off." Alternatively, to exit the vehicle's sunroof from starry sky mode, the user can speak or shout to the voice control system to input the "exit starry sky mode" command.

[0112] When the receiving device on the vehicle receives the instruction input by the user, it can send the instruction to the vehicle's domain controller. The vehicle's domain controller can then control the sunroof to exit the starry sky mode according to the instruction.

[0113] In some embodiments, the vehicle can control the sunshade device to move to expand the shading area of ​​the sunroof, and simultaneously extinguish the light-emitting elements blocked by the sunshade device to make the sunroof exit the starry sky mode and stop presenting the starry sky effect.

[0114] It can be understood that, in the process of extinguishing the light-emitting elements as the sunshade device moves, the purpose of stopping the starry sky effect in different areas and sections can be achieved.

[0115] When the vehicle's receiving device receives the "exit starry sky mode" command sent by the user, it will obtain the status of the sunshade device by reading the positional relationship between the sunshade device and the sunroof.

[0116] In some embodiments, when the instruction to exit the starry sky mode is an "open the sunroof" instruction input by the user, the vehicle can control the sunroof to be in an open state in response to the "open the sunroof" instruction, and control the light-emitting elements provided on the sunroof to be in an off state, thereby controlling the sunroof to exit the starry sky mode and stop presenting the starry sky effect.

[0117] It can be understood that, in the case where the sunroof is a movable device installed on the roof of the vehicle, the instruction to exit the starry sky mode can be an instruction to "open the sunroof".

[0118] In some embodiments, when the instruction to exit the starry sky mode is an instruction to "open the door", the vehicle can control the door to be in an open state and control the light-emitting element set on the sunroof to be in an off state in response to the instruction to "open the door", thereby controlling the sunroof to exit the starry sky mode and stop presenting the starry sky effect when the user gets off the vehicle.

[0119] Of course, the instruction to exit the starry sky mode can also be other forms of instructions, as long as it can trigger the exit of the starry sky mode. The embodiment of the present application will not be described in detail here.

[0120] It should be noted that the above description of at least one embodiment is merely illustrative and is in no way intended to limit the embodiment and its application or use.

[0121] The embodiment of the present application further provides a sunroof assembly for a vehicle, as shown in FIG5 , wherein the sunroof assembly 100 includes a sunroof 110 and a sunshade 120. The sunshade 120 is movable relative to the sunroof 110 to cover or expose the sunroof 110.

[0122] In an embodiment of the present application, the luminous area of ​​the skylight 110 can change with the change of the area of ​​the blocked area of ​​the skylight 110 by the shading device 120, and the difference between the luminous area of ​​the skylight 110 and the area of ​​the unblocked area of ​​the skylight 110 that is not blocked by the shading device is less than a preset value.

[0123] In some embodiments, a lighting device for lighting the sunroof is provided on the top of the vehicle. The lighting device extends along the longitudinal direction of the sunroof 110. The longitudinal direction of the sunroof 110 is the longitudinal direction of the vehicle.

[0124] In some embodiments, the light emitting device includes a plurality of light emitting elements, which are sequentially arranged along the longitudinal direction of the skylight 110 .

[0125] In some embodiments, the vehicle sunroof assembly 100 further includes a driving mechanism 130 and a lighting control device 140. The driving mechanism 130 is used to drive the sunshade device 120 to move relative to the sunroof 110, and the lighting control device 140 is used to adjust the lighting area of ​​the sunroof.

[0126] In some embodiments, the driving mechanism 130 is connected to the lighting control device 140. The driving mechanism 130 can also be used to send a first signal indicating the position of the sunshade device 120 relative to the skylight 110. The lighting control device 140 can also be used to adjust the lighting area of ​​the lighting device according to the first signal.

[0127] The first signal may include a signal indicating that the sunshade 120 is retracted. In this case, the lighting control device 140 may be configured to reduce the area of ​​the sunroof 110 blocked by the sunshade 120 based on the first signal, thereby increasing the sunroof's luminous area. Alternatively, the first signal may include a signal indicating that the sunshade 120 is deployed. In this case, the lighting control device 140 may increase the area of ​​the sunroof 110 blocked by the sunshade 120 based on the first signal, thereby reducing the sunroof's luminous area.

[0128] The sunroof assembly of a vehicle provided in an embodiment of the present application includes a sunroof and a sunshade device. The sunshade device can be moved relative to the sunroof to block or expose the sunroof. The difference between the luminous area of ​​the sunroof and the area of ​​the unblocked area of ​​the sunroof that is not blocked by the sunshade device is less than a preset value. In other words, during the movement of the sunshade device, the sunroof of the vehicle can be illuminated to present a starry sky effect. Compared with the method in which the starry sky effect can only be presented after the sunshade device moves to a position where it completely does not block the starry sky sunroof, on the one hand, it effectively shortens the time required for the sunroof to present the starry sky effect, thereby reducing the time the user spends waiting for the sunroof to present the starry sky effect, and effectively improving the user experience; on the other hand, it can enable the sunroof to present the starry sky effect in a zoned manner, thereby improving the flexibility of the starry sky effect presentation of the sunroof.

[0129] An embodiment of the present application provides a vehicle having a skylight, a sunshade device, and a light-emitting device disposed on the top of the vehicle, wherein the sunshade device is controlled by the control method described in any of the above embodiments.
