Description

Technical Field

[0001] Embodiments of the present application relate to the field of vehicle control technology, and more specifically, to a vehicle sunroof control method, a vehicle sunroof assembly, and a vehicle. Background Art

[0002] With the trend toward electrification and intelligent vehicles, simple-featured atmosphere sunroofs are no longer sufficient to meet the daily needs of users. To enhance the driving experience, more and more new energy vehicles are choosing to install starry sky sunroofs with richer patterns to create a more comfortable and romantic interior ambiance.

[0003] When the current starry sky sunroof is completely blocked, the user must first move the sunshade to an unblocked position to enjoy the starry sky effect. During this process, the user must passively wait for the sunshade to complete its movement before enjoying the starry sky effect. This undoubtedly increases user waiting time, making the starry sky mode unable to respond to user needs immediately, and thus reducing the user's driving experience. Summary of the Invention

[0036] 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] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] <Method Example>

[0042] Please see Figure 1 , Figure 1 The flowchart of the vehicle sunroof control method provided in an embodiment of the present application is shown. The method is applied to a vehicle and can be implemented by electronic equipment on the vehicle, such as a domain controller of the vehicle. The vehicle can be, for example, a sedan, off-road vehicle, SUV, or commercial vehicle. Of course, the vehicle can also be other types of vehicles, and the vehicle type is not specifically limited here.

[0043] In order to facilitate understanding of the method provided in the embodiment of the present application, the vehicle sunroof assembly involved in the embodiment of the present application is first introduced.

[0044] The vehicle sunroof assembly in the embodiment of the present application may include a sunroof and a sunshade device.

[0045] In practical applications, a sunroof can be a fixed device mounted on the roof of a vehicle, i.e., a closed sunroof, such as a closed panoramic sunroof. Alternatively, a sunroof can be a movable device mounted on the roof of a vehicle, i.e., an openable sunroof. Examples of openable sunroofs include recessed sunroofs and sliding sunroofs. Sunroofs can be panoramic or segmented. There is no particular limitation on the type of sunroof.

[0046] The sunshade device can be a sunshade curtain or a sunshade board.

[0047] A sunroof and a sunshade device can be installed on the roof of a vehicle. In some embodiments, the sunshade device is movably installed below the sunroof. For example, the sunshade device can be slidably installed below the sunroof. Of course, there are many specific structural forms and installation methods for the sunshade device, which will not be described in detail in this embodiment.

[0048] The vehicle sunroof assembly may further include a lighting device for illuminating the sunroof. The lighting device may extend in the longitudinal direction of the sunroof. The longitudinal direction of the sunroof 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.

[0049] In some embodiments, the light emitting element may be an LED light emitting diode. It is understood that there are many types of light emitting elements, which are not specifically limited here.

[0050] 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.

[0051] In some embodiments, the plurality of light-emitting elements may be divided into a plurality of groups, which may be distributed over the skylight using a light strip or other structure. For example, the plurality of light-emitting elements may be arranged equidistantly on a light strip, and the plurality of light strips may be arranged sequentially along the longitudinal direction of the skylight.

[0052] In actual applications, the movement of the sunshade can be controlled by the vehicle domain controller according to user needs. When the sunshade is retracted, the skylight is exposed. When the sunshade is deployed, the skylight is blocked. When the sunshade blocks the skylight, a sunshade effect can be achieved. When the sunshade exposes the skylight, the light-emitting device can illuminate the area of ​​the skylight that is not blocked by the sunshade to create a starry sky effect. Of course, when the sunshade exposes the skylight, the skylight can also have other functions, which will not be described in detail here.

[0053] In this embodiment, the starry sky effect refers to the display of a simulated night sky on the vehicle roof. The starry sky effect is achieved by covering the surface of the sunroof, which is located inside the vehicle, with fluorescent or reflective materials in the shape of stars or the moon, and then disposing multiple light-emitting elements on the periphery of this same surface. When these light-emitting elements are illuminated, the light emitted by the light-emitting elements hits the fluorescent or reflective materials on the sunroof, creating a starry sky atmosphere inside the vehicle.

[0054] By adjusting the color, brightness, and amount of the vehicle's interior ambient lighting, you can create different atmospheres and achieve different starry sky effects. When night falls, users can activate the vehicle's sunroof's starry sky mode to experience a variety of unique starry sky effects and relax. When on a date, users can activate the vehicle's sunroof's starry sky mode to create a unique and luxurious halo inside the vehicle, adding a touch of tenderness and romance.

[0055] The following describes the vehicle sunroof control method provided by the present application in conjunction with the accompanying drawings.

[0056] like Figure 1 As shown, the method for controlling a vehicle sunroof according to an embodiment of the present application may include the following steps S1100 to S1200.

[0057] Step S1100 , responding to an instruction to put the sunroof in starry sky mode.

[0058] In this embodiment, the instruction for setting the sunroof to starry sky mode may include a first instruction and a second instruction. The first instruction may cause the sunshade device to gradually illuminate while the sunshade device is slowly retracted. The second instruction may cause the sunshade device to gradually extinguish while the sunshade device is slowly deployed. The first and second instructions are interchangeable and are not limited herein.

[0059] In the first instruction, when the sunshade device is slowly retracted, the area of ​​the sunshade device blocking the skylight gradually decreases, and the area of ​​the non-blocking area gradually increases. Similarly, in the second instruction, when the sunshade device is slowly deployed, the area of ​​the sunshade device blocking the skylight gradually increases, and the area of ​​the non-blocking area gradually decreases.

[0060] The command for placing the sunroof in starry sky mode is determined based on a command input by the user. When the user input command is "enter starry sky mode" and "slowly retract the sunshade," the command for placing the sunroof in starry sky mode is determined to be the first command. When the user input command is "enter starry sky mode" and "slowly extend the sunshade," the command for placing the sunroof in starry sky mode is determined to be the second command.

[0061] In some embodiments, a receiving device for receiving user commands is installed on the vehicle. This receiving device can be, for example, 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 does not impose any further limitations.

[0062] 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 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, a fingerprint command, etc.

[0063] For example, when a user wants to enter Starry Sky Mode, they can touch the central control screen on the vehicle's computer to set the "Starry Sky Mode" option on the central control screen to "On." Alternatively, when a user wants to enter Starry Sky Mode, they can speak or shout to the voice control system to input the "Enter Starry Sky Mode" command.

[0064] 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.

[0065] After receiving the user instruction, the receiving device on the vehicle sends the user instruction to the vehicle domain controller. The vehicle domain controller determines whether the instruction for setting the sunroof in the starry sky mode is the first instruction or the second instruction based on the user instruction.

[0066] Step S1200 , controlling the light-emitting area of ​​the skylight and the area of ​​the shielding area of ​​the sunshade device according to the instruction to put the skylight in the starry sky mode.

[0067] In the embodiments of the present application, the shielding area of ​​the sunshade device is the area that blocks the skylight. Similarly, the non-shielding area of ​​the sunshade device is the area of ​​the skylight that is not blocked by the sunshade device. The luminous area of ​​the skylight can be the entire area not blocked by the sunshade device, or it can be a portion of the area.

[0068] The luminous area of ​​the skylight is the area of ​​the luminous region of the skylight. The movement of the sunshade device and the lighting or extinguishing of the light-emitting device may be asynchronous. For example, the speed at which the sunshade device is folded up may be faster than the speed at which the light-emitting device is lit up, that is, the light-emitting device in a small part of the non-blocking area of ​​the sunshade device does not emit light. Another example is that the speed at which the sunshade device is unfolded may be slower than the speed at which the light-emitting device is extinguished, that is, the light-emitting device in a small part of the blocked area of ​​the sunshade device does not extinguish. In an embodiment of the present application, the difference between the luminous area of ​​the skylight and the area of ​​the non-blocking area of ​​the sunshade device is less than a preset value.

[0069] In one example, this difference is primarily reflected in the difference between the sunroof's illuminated area and the sunshade's unobstructed area along the vehicle's longitudinal direction. This difference must be less than a preset difference. The closer the preset difference is to 0, the more synchronized the lighting and extinguishing of the light-emitting device and the retraction of the sunshade, or the extinguishing of the light-emitting device and the deployment of the sunshade, resulting in shorter user wait times and a better user experience. The preset difference can be set based on specific sunroof control requirements and is not specifically limited here.

[0070] In some embodiments, the ratio of the light-emitting area of ​​the skylight to the area of ​​the non-blocked area of ​​the sunshade device satisfies a preset ratio range. A closer value to 1 indicates a more synchronized lighting or extinguishing of the light-emitting device and retraction of the sunshade device, or a more synchronized extinguishing of the light-emitting device and deployment of the sunshade device. The preset ratio range can be set based on specific skylight control requirements and is not specifically limited herein.

[0071] The embodiment of the present application responds to an instruction to put the sunroof in starry sky mode, and controls the luminous area of ​​the sunroof and the area of ​​the blocking area of ​​the sunshade device according to the instruction, so that the difference between the luminous area of ​​the sunroof and the area of ​​the non-blocking area of ​​the sunshade device is less than a preset value. Through the above method, when the vehicle is in starry sky mode, as the area of ​​the non-blocking area of ​​the sunshade device increases, the luminous area of ​​the sunroof also increases continuously, and as the area of ​​the non-blocking area of ​​the sunshade device decreases, the luminous area of ​​the sunroof also decreases continuously. This can overcome the disadvantages of the traditional starry sky mode in which the lights can only be turned on or off as a whole, and need to wait for the sunshade device to move completely before they can be started. This can not only shorten the waiting time of the user, but also enhance the user experience by achieving the starry sky effect in a regional and segmented manner.

[0072] Based on the above description of the principle of realizing the starry sky effect, it can be known that before controlling the vehicle to enter the starry sky mode to realize the starry sky effect, it is necessary to control the sunroof to be in a completely closed state.

[0073] In one example, if the sunroof is a movable device mounted on the roof of a vehicle, before entering starry sky mode to achieve a starry sky effect, the sunroof must be controlled to close in advance to ensure that it is fully closed. In other words, the sunroof status must first be detected. If the sunroof is detected to be open, the sunroof must be controlled to close to fully close.

[0074] In another example, if the sunroof is a fixed device installed on the roof of the vehicle, such as a fixed panoramic sunroof, there is no need to perform the step of detecting the position of the sunroof.

[0075] In the embodiments of the present application, the sunroof and the light-emitting elements disposed thereon may be blocked by the sunshade device. Therefore, in order to achieve a starry sky effect by illuminating the sunroof with the light-emitting elements, it is necessary to obtain the status of the sunshade device in advance to determine whether the vehicle can achieve the starry sky effect.

[0076] In some embodiments, the state of the sunshade device is obtained in response to a command to place the sunroof in starry sky mode. When a receiving device in the vehicle receives a user input command to place the sunroof in starry sky mode, the receiving device obtains the state of the sunshade device by reading the relative positional relationship between the sunshade device and the sunroof.

[0077] In some embodiments, after the vehicle receives an instruction to put the sunroof in starry sky mode through a receiving device, it will determine the status of the sunroof under the command of the domain controller. While ensuring that the sunroof is in a completely closed state, it will continue to read the relative position relationship between the sunshade device and the sunroof, thereby obtaining the status of the sunshade device.

[0078] The state of the sunshade device may include a blocking state and an unblocked state. The unblocked state refers to a completely unblocked state. The blocking state includes a partially blocking state and a completely blocking state. When the sunshade device is in a partially blocking state, the non-blocking area of ​​the sunshade device includes an original non-blocking area and a new non-blocking area. The original non-blocking area is the non-blocking area before the sunshade device moves. The new non-blocking area is the non-blocking area added during the movement of the sunshade device. The blocking area of ​​the sunshade device includes an original blocking area and a new blocking area. The original blocking area is the blocking area before the sunshade device moves. The new blocking area is the blocking area added during the movement of the sunshade device.

[0079] In some embodiments, as Figure 2 As shown, step S1200 may include steps S2100 to S2200.

[0080] Step S2100: controlling the sunshade device to move according to the first instruction to increase the area of ​​the non-shielding region of the sunshade device.

[0081] In this embodiment, controlling the movement of the sunshade device is controlling the folding of the sunshade device, so that the area of ​​the sunroof blocked is reduced, thereby increasing the area of ​​the non-blocking area of ​​the sunshade device.

[0082] Step S2200: Control the light emitting elements according to the first instruction, so that the light emitting elements located in the non-blocking area are in a light-on state, and the light emitting elements located in the blocking area are in a dark state.

[0083] Lighting up the light emitting elements in the non-blocking area may include lighting up the light emitting elements in the current non-blocking area, and may also include lighting up the light emitting elements in a new non-blocking area that is added as the sunshade device is retracted.

[0084] The light emitting elements that illuminate the non-blocked area can be illuminated synchronously with the movement of the sunshade device, or can be illuminated when the difference between the non-blocked area of ​​the sunshade device and the area of ​​the current luminous area of ​​the skylight increases to a preset value.

[0085] 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. In one possible implementation, the sensor may be a Hall effect element.

[0086] In one example, when the vehicle's domain controller detects movement of the sunshade, it receives a Hall effect signal. This signal also determines the sunshade's travel distance S1 and simultaneously illuminates the light-emitting elements within this distance. Assuming multiple light-emitting elements are evenly spaced across the sunroof, with the distance between adjacent elements being S2, the number of light-emitting elements illuminated during movement, N, equals S1 / S2.

[0087] In the embodiment of the present application, the light-emitting elements located in the shielding area are always in an off state, which can reduce unnecessary energy waste.

[0088] In some embodiments, when the sunshade device is in a partially blocked state, such as Figure 3 As shown, step 1200 may further include steps S3100 to S3200.

[0089] Step S3100: Control the light-emitting elements according to the first instruction so that the light-emitting elements located in the original non-blocking area are in a light-on state.

[0090] Step S3200, controlling the sunshade device to move according to the first instruction to increase the area of ​​the non-blocking area, so that the light-emitting elements located in the new non-blocking area are in a lit state, and the light-emitting elements located in the blocking area are in an extinguished state.

[0091] In some embodiments, in step S3200, the sunshade device can be controlled to move according to the first instruction to increase the area of ​​the non-blocking area, and the light-emitting elements in the new non-blocking area can be simultaneously illuminated. This can further reduce user waiting time and improve user experience.

[0092] 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.

[0093] In one example, when the vehicle's domain controller detects movement of the sunshade, it receives a Hall effect signal. This signal then determines the sunshade's position and the distance S1 to the unobstructed area on the sunroof. The controller then simultaneously illuminates the light-emitting elements within S1 of the unobstructed area. Assuming multiple light-emitting elements are evenly spaced across the sunroof, with a distance S2 between adjacent elements, the number of light-emitting elements pre-activated before the sunshade moves (N1) equals S1 / S2.

[0094] When the vehicle's domain controller illuminates the light-emitting elements within the unobstructed area of ​​the sunshade, it controls the sunshade to move and obtains the travel distance S3. As the sunshade moves, it also illuminates the light-emitting elements within the travel distance S3. In this case, the number of illuminated light-emitting elements N2 = S3 / S2.

[0095] In some embodiments, when the sunshade device is in the fully shielding state, the sunshade device will completely shield the skylight. In this case, Figure 4 As shown, step 1200 may further include step S4100.

[0096] Step 4100: Control the sunshade device to move according to the first instruction to increase the area of ​​the non-blocking area, and synchronously light up the light-emitting elements located in the new non-blocking area.

[0097] In this embodiment, because the vehicle roof is provided with a light-emitting device extending in the longitudinal direction of the sunroof for illuminating the sunroof, when the sunshade is controlled to move to increase the area of ​​the unobstructed area of ​​the sunshade, the light-emitting elements not obstructed by the sunshade are also illuminated, thereby achieving a starry sky effect by illuminating the light-emitting elements in a segmented and zoned manner. Furthermore, when the sunshade is controlled to move to increase the area of ​​the unobstructed area of ​​the sunshade, the light-emitting elements in the obstructed area are extinguished, thereby reducing energy waste.

[0098] In some embodiments, as Figure 5 As shown, step S1200 may further include steps S5100 to S5200.

[0099] Step S5100: Control the sunshade device to move according to the second instruction to increase the area of ​​the sunshade region.

[0100] In this embodiment, controlling the movement of the sunshade device is controlling the sunshade device to unfold, so that the area of ​​the unblocked region of the skylight is reduced, thereby increasing the area of ​​the blocked region of the sunshade device.

[0101] Step S5200: Control the light emitting elements according to the second instruction, so that the light emitting elements located in the non-blocking area are in a light-on state, and the light emitting elements located in the blocking area are in a dark state.

[0102] Turning off the light emitting elements in the shielding area may include turning off the light emitting elements in the current non-shielding area, and may also include turning off the light emitting elements in the new shielding area added as the sunshade device is deployed.

[0103] The light emitting elements in the blocked area may be extinguished synchronously with the movement of the sunshade device, or may be extinguished when the difference between the unblocked area of ​​the sunshade device and the area of ​​the current luminous area of ​​the skylight increases to a preset value.

[0104] In some embodiments, when the sunshade device is in a partially blocked state, such as Figure 6 As shown, step 1200 may further include steps S6100 to S6200.

[0105] Step S6100: Control the light-emitting elements according to the second instruction, so that the light-emitting elements located in the original blocking area are in an off state.

[0106] Step S6200: Control the sunshade device to move according to the second instruction to increase the area of ​​the shielding area, so that the light-emitting elements located in the new shielding area are in an extinguished state, and the light-emitting elements located in the non-shielding area are in a lit state.

[0107] In some embodiments, in step S6200, the sunshade device can be controlled to move according to the second instruction to increase the area of ​​the shielding area, and the light-emitting elements in the new shielding area can be extinguished simultaneously. This can further reduce user waiting time, improve user experience, and reduce energy waste.

[0108] 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 non-shielding area may be extinguished synchronously.

[0109] The method for determining the number of light-emitting elements extinguished before the sunshade device moves and the number of light-emitting elements extinguished during the movement is similar 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.

[0110] In some embodiments, when the sunshade device is in a completely unblocked state, the sunshade device will completely expose the skylight. In this case, all the light-emitting elements on the skylight are in a lighted state. Figure 7 As shown, step 1200 may further include step S7100.

[0111] Step S7100: Control the sunshade device to move according to the second instruction to increase the area of ​​the shielding region, and simultaneously extinguish the light-emitting elements located in the new shielding region.

[0112] In the embodiment of the present application, when the sunshade device is controlled to move to increase the area of ​​the sunshade's shielding area, the light-emitting elements blocked by the sunshade device can also be extinguished, thereby achieving a starry sky effect by extinguishing the light-emitting elements in a regional and segmented manner. In addition, when the sunshade device is controlled to move to increase the area of ​​the sunshade's shielding area, the light-emitting elements in the non-shielded area remain illuminated, which also facilitates the user to observe the real-time starry sky effect and quickly adjust to the area of ​​the user's needs.

[0113] In some embodiments, during the execution of step 2100 or step 5100, the sunroof control method provided in the embodiment of the present application may further include step S8100.

[0114] Step S8100: During the process of controlling the movement of the sunshade device, if a third instruction to stop the movement of the sunshade device is received, the sunshade device is controlled to stop moving and the current state of the light-emitting device is maintained.

[0115] The third command is a command to stop the movement of the sunshade device. The third command generally refers to any form of signal input that can control the sunshade device to stop moving. In some embodiments, the third command can be any of the following: a touch command, a voice command, a gesture command, an expression command, a fingerprint command, etc.

[0116] When the vehicle enters starry sky mode, the light-emitting elements not blocked by the sunshade will be illuminated synchronously with the movement of the sunshade, achieving the purpose of a starry sky effect in a regional and segmented manner. If at a certain moment, the user desires to experience the starry sky effect in a certain area, a third command can be issued to stop the sunshade from moving. In this case, the sunshade will stop moving, and the already illuminated light-emitting elements will remain illuminated, ensuring that the vehicle can achieve a starry sky effect in a regional and segmented manner, thereby meeting the different needs of users.

[0117] In some embodiments, as Figure 8 As shown, the method for controlling the vehicle sunroof according to the embodiment of the present application may further include step S1300.

[0118] Step S1300: in response to the instruction to exit the starry sky mode, control the light emitting device to be in an off state.

[0119] 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; an instruction to close the starry sky mode.

[0120] In some embodiments, before exiting the starry sky mode, the vehicle must receive an "exit starry sky mode" command from the user. Specifically, the vehicle is equipped with a receiving device for receiving the command. The receiving device can be a receiving device that receives the first command and the second command. The "exit starry sky mode" command generally refers to any form of signal input that can cause the vehicle to exit the starry sky mode. In some embodiments, the "exit starry sky mode" command can be any of the following forms of commands: touch command, voice command, gesture command, expression command, fingerprint command, etc.

[0121] For example, to exit Starry Sky Mode, the user can touch the central control screen on the vehicle's computer to set the "Starry Sky Mode" option on the central control screen to "Off." Alternatively, to exit Starry Sky Mode, the user can speak or shout to the voice control system to enter the "Exit Starry Sky Mode" command. Upon receiving the user command, the vehicle's receiving device sends it to the vehicle domain controller. Based on the user command, the vehicle domain controller controls the sunroof to exit Starry Sky Mode.

[0122] In some embodiments, when a receiving device in a vehicle receives an "exit starry sky mode" command sent by a user, it obtains the status of the sunshade device by reading the positional relationship between the sunshade device and the sunroof glass.

[0123] In one example, when the sunshade device is in an unblocked state, the sunshade device does not block the skylight. In this case, the sunshade device is controlled to move to expand the blocking area, and the light-emitting elements blocked by the sunshade device are extinguished simultaneously, thereby achieving the purpose of stopping the starry sky effect in a zoned and segmented manner.

[0124] In another example, when the sunshade device is in a semi-blocking state, the sunshade device partially blocks the skylight. In this case, the light-emitting elements of the skylight portion blocked by the sunshade device are in an extinguished state. Therefore, the sunshade device can be directly controlled to move to expand the blocking area, and the light-emitting elements blocked by the sunshade device can be extinguished synchronously, thereby achieving the purpose of stopping the starry sky effect.

[0125] In some embodiments, before exiting the starry sky mode, the vehicle can receive an "open the sunroof" command input from the user. After receiving the "open the sunroof" command, the sunroof will be set to the open state, and the light-emitting element set on the sunroof will be set to the off state, thereby realizing the function of stopping the starry sky effect to exit the starry sky mode.

[0126] In some embodiments, the vehicle may also receive an "open door" command to stop the starry sky effect and exit starry sky mode.

[0127] For example, in response to the "open door" command, the door can be set to open and the light-emitting element on the sunroof can be set to extinguish, thereby realizing the function of stopping the starry sky effect and exiting the starry sky mode when the user gets out of the car.

[0128] In some embodiments, the vehicle may also directly receive a command to "turn off starry sky mode."

[0129] 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. This embodiment will not be described in detail here.

[0130] 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.

[0131] <Device Example>

[0132] The present application also provides a vehicle sunroof assembly, such as Figure 9 As shown, the vehicle sunroof assembly 100 includes a sunroof 110 and a sunshade device 120 .

[0133] The sunshade device 120 is movable relative to the sunroof 110 to cover or reveal the sunroof 110 .

[0134] In an embodiment of the present application, the luminous area of ​​the skylight 110 changes with the area of ​​the blocked area of ​​the shading device 120, and the difference between the luminous area of ​​the skylight 110 and the area of ​​the unblocked area of ​​the shading device is less than a preset value.

[0135] In some embodiments, a lighting device for illuminating the sunroof is provided on the top of the vehicle, and the lighting device extends along the longitudinal direction of the sunroof 110 .

[0136] 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 .

[0137] In some embodiments, the vehicle sunroof assembly 100 also 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. The driving mechanism 130 and the lighting control device 140 are connected.

[0138] In some embodiments, the driving mechanism 130 is configured to emit a first signal representing the position of the sunshade device 120 relative to the skylight 110 , and the lighting control device 140 adjusts the lighting area of ​​the lighting device according to the first signal.

[0139] The first signal may include a signal indicating that the sunshade device 120 is retracted. Based on the first signal, the lighting control device reduces the shielding area of ​​the sunshade device 120 and correspondingly increases the luminous area of ​​the sunroof. The first signal may also include a signal indicating that the sunshade device 120 is deployed. Based on the first signal, the lighting control device increases the shielding area of ​​the sunshade device 120 and correspondingly reduces the luminous area of ​​the sunroof.

[0140] The vehicle sunroof assembly of the embodiment of the present application responds to an instruction to put the sunroof in starry sky mode, and controls the luminous area of ​​the sunroof and the area of ​​the blocking area of ​​the sunshade device according to the instruction, and the difference between the luminous area of ​​the sunroof and the area of ​​the non-blocking area of ​​the sunshade device is less than a preset value. Through the above method, when the vehicle is in starry sky mode, as the area of ​​the non-blocking area of ​​the sunshade device increases, the luminous area of ​​the sunroof also increases continuously, and as the area of ​​the non-blocking area of ​​the sunshade device decreases, the luminous area of ​​the sunroof also decreases continuously, thereby achieving a starry sky effect in a zoned and segmented manner, so as to solve the disadvantage that the lights in the traditional starry sky mode can only be turned on or off as a whole, and need to wait for the sunshade device to move completely before they can be started. This not only saves the user's time, but also improves the user experience by achieving the starry sky effect in a zoned and segmented manner.

[0141] The present application also provides a vehicle having a sunroof, a sunshade, and a light-emitting device disposed on the top of the vehicle, and the vehicle uses the control method described in any of the above embodiments to control the sunroof, the sunshade, and the light-emitting device.
