[0026] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present disclosure.

[0027] In the description of this disclosure, unless otherwise specified, " / " means "or". For example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more. Expressions such as "first" and "second" do not limit the quantity and execution order, and expressions such as "first" and "second" do not necessarily limit them to be different.

[0028] It should be noted that in this disclosure, expressions such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of expressions such as "exemplarily" or "for example" is intended to present the relevant concepts in a detailed manner.

[0029] Currently, to address the technical problem of ensuring that sun visors provide shade while avoiding obstruction to the driver's vision, a sun visor can be constructed using a combination of an LCD display and a camera. This visor can use the imagery captured by the camera to further determine the shadow cast by the sun on the driver's face, and calculate the area of ​​the visor that affects the driver's vision. By adjusting the LCD display, the portion of the visor that projects sunlight onto the driver's eyes becomes darker, while the rest of the panel remains transparent, ensuring a clear field of vision. However, this solution presents significant technical challenges and costs, and is therefore less practical.

[0030] In light of this, embodiments of the present disclosure provide a sun visor control method, comprising: obtaining light intensity at the sun visor; and adjusting the light transmittance of the sun visor based on the light intensity. This method can adjust the light transmittance of the sun visor based on the real-time detected light intensity inside and outside the sun visor, ensuring that the light transmittance is within a preset safety range, thereby improving vehicle driving safety.

[0031] FIG1 is a schematic structural diagram of a sun visor provided in an embodiment of the present disclosure. As shown in FIG1 , the sun visor 100 includes a sun visor body 10 , a light sensor 20 and a controller 30 .

[0032] It should be noted that the sun visor 100 can usually be set to the front part of the roof corresponding to the driver and / or co-driver, and is used to provide the driver and passengers with the function of blocking sunlight, strong light and other dazzling light. The sun visor 100 can be flipped forward or sideways to a suitable position when in use, and can be folded against the roof when not in use.

[0033] The sun visor body 10 can be used to block sunlight, strong sunlight, and other glare for the driver and passengers. In some embodiments, the sun visor body 10 can be equipped with a vanity mirror / mirror cover / mirror light to facilitate makeup application and lighting. Alternatively, the sun visor body can be equipped with a strap / ticket holder to secure invoices, receipts, business cards, etc.

[0034] In some embodiments, the sun visor body 10 can be made of a material with adjustable light transmittance. For example, the sun visor body 10 can be made of glass with adjustable light transmittance, such as electrically controlled atomized glass, and the sun visor body 10 can adjust the light transmittance by segmented adjustment, stepless adjustment, or regional adjustment.

[0035] In some embodiments, the sun visor body 10 may include a first sun visor and a second sun visor, the first sun visor being the front windshield of the vehicle made of a material with adjustable light transmittance, and the second sun visor being any one of the corner window glass, rear windshield, sunroof or roof glass of the vehicle made of a material with adjustable light transmittance.

[0036] The light sensor 20 is disposed on the sun visor body 10 and is used to detect the light intensity of the sun visor.

[0037] In some embodiments, the light sensor 20 includes a first light sensor and / or a second light sensor. For example, as shown in FIG2 , the light sensors on the sun visor 100 include a first light sensor 21 and a second light sensor 22. The first light sensor 21 is disposed on the side of the sun visor body 10 facing the vehicle interior and is used to detect the light intensity inside the sun visor 100. The inside light intensity is the light intensity detected on the side of the sun visor 100 facing the vehicle interior, incident from the vehicle exterior to the vehicle interior. The second light sensor 22 is disposed on the side of the sun visor 100 facing the vehicle exterior and is used to detect the light intensity outside the sun visor 100. The outside light intensity is the light intensity detected on the side of the sun visor 100 facing the vehicle exterior, incident from the vehicle exterior to the vehicle interior. It should be understood that the sun visor 100 is in use.

[0038] The controller 30 may be connected to the light sensor 20. The controller 30 is configured to control the sun visor 100. In some embodiments, the controller 30 may detect the light intensity of the sun visor 100 via the light sensor and adjust the light transmittance of the sun visor 100 based on the light intensity of the sun visor 100. In some embodiments, the sun visor 100 includes a first sun visor and a second sun visor. The controller 30 may be configured to adjust the light transmittance of the first sun visor based on the light intensity of the first sun visor and a first light intensity threshold. Furthermore, the controller 30 may be configured to adjust the light transmittance of the second sun visor based on the light intensity of the second sun visor and the second light intensity threshold.

[0039] It is understandable that the system architecture shown in FIG1 does not constitute a limitation on the embodiments of the present disclosure, and it may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0040] In some embodiments, the present disclosure also provides a control device for a sun visor (hereinafter referred to as the control device in the embodiments of the present disclosure). The control device is an electronic device with data processing capabilities. For example, the control device can be the controller of the sun visor 100. Alternatively, the control device can be another electronic device with data processing capabilities connected to the controller of the sun visor 100, or a functional module in the electronic device (such as a vehicle computer, user equipment, etc.). The embodiments of the present disclosure are not limited to this. The execution entity of the sun visor control method provided in the embodiments of the present disclosure is the control device.

[0041] The following describes the embodiments provided by the present disclosure in conjunction with the accompanying drawings.

[0042] As shown in FIG3 , an embodiment of the present disclosure provides a method for controlling a sun visor, and the method for controlling a sun visor includes the following steps.

[0043] S101: Obtain the light intensity of the sun visor.

[0044] The illumination intensity of the sun visor may be the illumination intensity of light incident on the sun visor from the outside of the vehicle to the inside of the vehicle.

[0045] In some embodiments, the light intensity of the visor includes an inside light intensity and / or an outside light intensity.

[0046] The inner side illumination intensity of the sun visor is the illumination intensity of the incident light from the outside of the vehicle to the inside of the vehicle detected on the side surface of the sun visor facing the inside of the vehicle. It should be understood that the sun visor is in use.

[0047] In some embodiments, the interior light intensity may be determined based on at least one first light sensor disposed on the sun visor, wherein the first light sensor is disposed on a surface of the sun visor facing the interior of the vehicle.

[0048] For example, the control device may obtain a first light intensity detected by at least one first light sensor and determine the light intensity on the inner side of the sun visor based on the at least one first light intensity. For example, the control device may determine an average value, a maximum value, etc. of the at least one first light intensity as the light intensity on the inner side of the sun visor.

[0049] In addition, the external light intensity is the light intensity detected on the side surface of the sun visor facing the outside of the vehicle, with the illumination direction being from the outside of the vehicle to the inside of the vehicle. It should be understood that the sun visor is in use.

[0050] In some embodiments, the external light intensity may be determined based on at least one second light sensor disposed on the sun visor, wherein the second light sensor is disposed on a surface of the sun visor facing the interior of the vehicle.

[0051] For example, the control device may obtain the second light intensity detected by the at least one second light sensor and determine the light intensity outside the sun visor based on the at least one second light intensity. For example, the control device may determine the light intensity outside the sun visor as an average value, a maximum value, or the like of the at least one second light intensity.

[0052] In some embodiments, the control device may periodically obtain the light intensity of the sun visor at a preset frequency, such as once per second, once per 60 seconds, or once per 0.5 seconds.

[0053] It should be noted that if a user needs to use the sun visor to block sunlight, the user can use the sun visor. For example, the user can adjust the sun visor to the downward-folded position shown in Figure 2, in which case the sun visor is in use. In this case, the control device can periodically obtain the light intensity of the sun visor at a preset frequency to promptly update the current light intensity and adjust the light transmittance of the sun visor in real time based on the obtained light intensity.

[0054] In some embodiments, as shown in FIG. 4 , the sun visor 100 may include multiple sub-areas, and the control device may obtain the light intensity of each of the multiple sub-areas of the sun visor.

[0055] For example, for any sub-area, the illumination intensity of the sub-area may include the illumination intensity of light incident on the sub-area of ​​the sun visor from the vehicle exterior to the vehicle interior. Furthermore, the illumination intensity of the sub-area includes the inner illumination intensity and / or the outer illumination intensity. In some embodiments, the inner illumination intensity of the sub-area may be determined based on the illumination intensity detected by a first illumination sensor disposed in the sub-area. The outer illumination intensity of the sub-area may be determined based on the illumination intensity detected by a second illumination sensor disposed in the sub-area.

[0056] S102: Adjust the light transmittance of the sun visor according to the light intensity of the sun visor.

[0057] In some embodiments, when the vehicle is in motion, the control device may adjust the light transmittance of the sun visor according to the light intensity of the sun visor.

[0058] In some embodiments, the control device may adjust the light transmittance of the sun visor based on the acquired inner light intensity and / or outer light intensity of the sun visor. Exemplarily, the control device may adjust the light transmittance of the sun visor based on at least the following implementations.

[0059] Implementation method 1: The light intensity of the sun visor includes the light intensity on the inner side. The control device adjusts the light transmittance of the sun visor according to the light intensity on the inner side of the sun visor.

[0060] For example, the control device may determine a comparison between the light intensity on the inner side of the sun visor and a light intensity threshold, and adjust the light transmittance of the sun visor based on this comparison. The light intensity threshold may be set based on an actual light intensity value that does not affect the driver's vision. Furthermore, the light intensity value may be pre-set in the sun visor or control device, set by the user, or set by other means.

[0061] In one example, the control device reduces the light transmittance of the sun visor when the inner light intensity is greater than a light intensity threshold.

[0062] In some embodiments, the control device may determine the adjusted transmittance as the difference between the sun visor's current transmittance and the transmittance adjustment value based on a preset transmittance adjustment value. Alternatively, the control device may determine the adjusted transmittance based on the sun visor's transmittance corresponding to the light intensity threshold and the sun visor's current transmittance.

[0063] It's important to note that the interior light intensity is detected by a first light sensor on the side of the sun visor facing the vehicle's interior. Since the first light sensor is located closer to the driver, the interior light intensity is closer to the actual incident light intensity perceived by the driver. Therefore, if the interior light intensity exceeds the light intensity threshold, it indicates that the current light intensity is excessive, affecting the driver's vision and, in turn, the vehicle's driving safety. Therefore, it's necessary to reduce the sun visor's light transmittance to lower the driver's perceived light intensity and improve driving safety.

[0064] In another example, when the inner light intensity is less than or equal to the light intensity threshold, the control device maintains the light transmittance of the sun visor unchanged, or increases the light transmittance of the sun visor.

[0065] In some embodiments, the control device may obtain an initial light transmittance of the sun visor when it is activated and further adjust the light transmittance of the sun visor based on the initial light transmittance, the inner light intensity, and the light intensity threshold.

[0066] Exemplarily, the control device may maintain the light transmittance of the sun visor unchanged when the initial light transmittance is the maximum value of the light transmittance adjustable range and the inner light intensity is less than or equal to the light intensity threshold.

[0067] It should be noted that when the sun visor is activated, that is, when the sun visor first enters the aforementioned usage state, the default transmittance may be the maximum value of the adjustable transmittance range. Therefore, as the sun visor continues to be used, the transmittance of the sun visor may gradually decrease from the maximum value, that is, the current transmittance of the sun visor is at a relatively high value. Therefore, when the inner light intensity is less than or equal to the light intensity threshold, the transmittance of the sun visor can be maintained unchanged, thereby maintaining a relatively high transmittance while meeting the user's sun protection needs and preventing the sun visor from obstructing the driver's vision.

[0068] Alternatively, the control device may increase the light transmittance of the sun visor when the initial light transmittance is the minimum value of the light transmittance adjustable range and the inner light intensity is less than or equal to the light intensity threshold.

[0069] In some embodiments, the control device may determine the adjusted transmittance as the sum of the sun visor's current transmittance and the transmittance adjustment value based on a preset transmittance adjustment value. Alternatively, the control device may determine the increased transmittance based on the sun visor's transmittance corresponding to the light intensity threshold and the sun visor's current transmittance.

[0070] It should be noted that when the sun visor is activated, that is, when the sun visor first enters the aforementioned usage state, the default transmittance may be the minimum value of the adjustable transmittance range. Therefore, as the sun visor continues to be used, the transmittance of the sun visor may gradually increase from the minimum value, that is, the current transmittance of the sun visor is at a low value. Furthermore, when the inner light intensity is less than or equal to the light intensity threshold, the transmittance of the sun visor may be increased to maintain a high transmittance while meeting the user's sun protection needs, thereby preventing the sun visor from obstructing the driver's vision.

[0071] In some embodiments, the control device may further reacquire the light intensity on the inner side of the sun visor after adjusting the light transmittance of the sun visor, and adjust the light transmittance of the sun visor based on the reacquired light intensity on the inner side of the sun visor. It should be understood that the control device may reacquire the light intensity on the inner side of the sun visor and adjust the light transmittance of the sun visor multiple times so that the light intensity on the inner side of the sun visor meets the light intensity threshold.

[0072] Implementation method 2: The illumination intensity of the sun visor includes the illumination intensity of the outside light. The control device adjusts the illumination intensity of the sun visor according to the illumination intensity of the outside light of the sun visor.

[0073] For example, the control device may determine a comparison result between the external light intensity of the sun visor and a light intensity threshold, and adjust the light transmittance of the sun visor based on the comparison result. In some embodiments, the light intensity threshold corresponding to the external light intensity may be equal to the light intensity threshold corresponding to the internal light intensity, or the light intensity threshold corresponding to the external light intensity may be different from the light intensity threshold corresponding to the internal light intensity.

[0074] In one example, the control device reduces the light transmittance of the sun visor when the outside light intensity is greater than a light intensity threshold.

[0075] In some embodiments, the control device may determine the adjusted transmittance as the difference between the sun visor's current transmittance and the transmittance adjustment value based on a preset transmittance adjustment value. Alternatively, the control device may determine the adjusted transmittance based on the sun visor's transmittance corresponding to the light intensity threshold and the sun visor's current transmittance.

[0076] It should be noted that if the external light intensity exceeds the light intensity threshold, it indicates that the current light intensity is too high, which may affect the driver's vision and thus affect the driving safety of the vehicle. Therefore, it is necessary to reduce the light transmittance of the sun visor to reduce the light intensity perceived by the driver and improve driving safety.

[0077] In another example, the control device increases the light transmittance of the sun visor when the outside light intensity is less than or equal to the light intensity threshold.

[0078] In some embodiments, the control device may determine the adjusted transmittance as the sum of the sun visor's current transmittance and the transmittance adjustment value based on a preset transmittance adjustment value. Alternatively, the control device may determine the increased transmittance based on the sun visor's transmittance corresponding to the light intensity threshold and the sun visor's current transmittance.

[0079] In some embodiments, the control device can adjust the light transmittance of the sun visor to a maximum value of the adjustable light transmittance range.

[0080] In some embodiments, the control device may further reacquire the external light intensity of the sun visor after adjusting the transmittance of the sun visor, and adjust the transmittance of the sun visor based on the reacquired external light intensity of the sun visor. It should be understood that the control device may reacquire the external light intensity of the sun visor and adjust the transmittance of the sun visor multiple times to ensure that the external light intensity of the sun visor meets the light intensity threshold.

[0081] In implementation mode 3, the light intensity of the sun visor includes the light intensity on the inner side and the light intensity on the outer side. The control device can adjust the light transmittance of the sun visor according to the light intensity on the inner side and the light intensity on the outer side of the sun visor.

[0082] Exemplarily, the control device may determine a comparison result between the inner light intensity of the sun visor and a light intensity threshold, and a comparison result between the outer light intensity and the light intensity threshold, and adjust the transmittance of the sun visor based on the two comparison results obtained.

[0083] In one example, the control device reduces the light transmittance of the sun visor when both the outside light intensity and the inside light intensity are greater than a light intensity threshold.

[0084] The detailed process of reducing the light transmittance of the sun visor can refer to the relevant description in the above implementation method 1, which will not be repeated here.

[0085] In another example, the control device increases the light transmittance of the sun visor when the outside light intensity and the inside light intensity are both less than or equal to the light intensity threshold.

[0086] The detailed process of increasing the light transmittance of the sun visor can refer to the relevant description in the above implementation method 1, which will not be repeated here.

[0087] In another example, the control device maintains the transmittance of the sun visor unchanged, or increases the transmittance of the sun visor when the outside light intensity is greater than the light intensity threshold and the inside light intensity is less than or equal to the light intensity threshold.

[0088] It should be noted that the outside light intensity is detected by the second light sensor on the side of the sun visor facing the vehicle's exterior, while the inside light intensity is detected by the first light sensor on the side of the sun visor facing the vehicle's interior. Since the second light sensor is located closer to the vehicle's surroundings and the first light sensor is located closer to the driver, the outside light intensity may be greater than the inside light intensity, and the inside light intensity is closer to the intensity of incident light actually perceived by the driver. Therefore, if the outside light intensity is greater than the light intensity threshold and the inside light intensity is less than or equal to the light intensity threshold, the current light transmittance of the sun visor meets the user's light-shielding requirements. Therefore, the control device can maintain the sun visor's light transmittance unchanged or increase it.

[0089] In some embodiments, the control device can maintain the transmittance of the sun visor unchanged when the initial transmittance is the maximum value of the adjustable transmittance range, the outside light intensity is greater than the light intensity threshold, and the inside light intensity is less than or equal to the light intensity threshold.

[0090] Alternatively, the control device may increase the transmittance of the sun visor when the initial transmittance is the minimum value of the adjustable transmittance range, the outer light intensity is greater than the light intensity threshold, and the inner light intensity is less than or equal to the light intensity threshold.

[0091] In some embodiments, the control device may further reacquire the inner and outer light intensities of the sun visor after adjusting the transmittance of the sun visor, and adjust the transmittance of the sun visor based on the reacquired inner and outer light intensities. It should be understood that the control device may reacquire the inner and outer light intensities of the sun visor multiple times and adjust the transmittance of the sun visor so that the inner and outer light intensities of the sun visor meet the light intensity threshold.

[0092] In some embodiments, when the sun visor includes multiple sub-regions, the control device may adjust the light transmittance of each sub-region of the sun visor based on the light intensity of each sub-region of the sun visor. For example, for any sub-region of the sun visor, the control device may adjust the light transmittance of that sub-region of the sun visor based on the methods described in Implementation 1, Implementation 2, or Implementation 3 above, which will not be further described here.

[0093] In one implementation, the sun visor is arranged on the front windshield of the vehicle.

[0094] In another implementation, the sun visor includes a first sun visor and a second sun visor, the first sun visor is the front windshield of the vehicle with adjustable light transmittance, and the second sun visor is any one of the corner window glass, rear windshield, sunroof or roof glass of the vehicle with adjustable light transmittance.

[0095] In some embodiments, the control device can adjust the transmittance of the first sun visor according to the light intensity of the first sun visor and the first light intensity threshold, and adjust the transmittance of the second sun visor according to the light intensity of the second sun visor and the second light intensity threshold.

[0096] For example, the first light intensity threshold can be set based on an actual light intensity value that does not affect the driver's line of sight. The second light intensity threshold can be set based on a light intensity value that satisfies the comfort of passengers in the vehicle. In some embodiments, the value of the first light intensity threshold can be equal to the second light intensity threshold. Alternatively, the value of the first light intensity threshold can also be equal to the second light intensity threshold.

[0097] The control device can adjust the light transmittance of the first sun visor according to the light intensity of the first sun visor and the first light intensity threshold, in combination with the method shown in, for example, Implementation 1, Implementation 2, or Implementation 3 above. The control device can also adjust the light transmittance of the second sun visor according to the light intensity of the second sun visor and the second light intensity threshold, in combination with the method shown in, for example, Implementation 1, Implementation 2, or Implementation 3 above.

[0098] It should be noted that the vehicle's sun visor can be combined with the vehicle's entire glass, and then, based on the needs of passengers at different positions in the vehicle, the transmittance of each position of the vehicle's glass can be intelligently controlled to improve the vehicle's riding experience.

[0099] In some embodiments, before the vehicle enters the driving state, the control device can set both the first sun visor and the second sun visor to the maximum value of the adjustable light transmittance range, so as to prevent the sun visors from blocking the driver's vision.

[0100] In some embodiments, when the vehicle is in a driving state, the control device can adjust the transmittance of the first sun visor according to the light intensity of the first sun visor and the first light intensity threshold, and adjust the transmittance of the second sun visor according to the light intensity of the second sun visor and the second light intensity threshold.

[0101] In some embodiments, in response to the vehicle entering the ignition-off state, the control device may adjust the light transmittance of the second sun visor to the minimum value of the light transmittance adjustable range. This can prevent the vehicle from being exposed to the sun in an outdoor parking lot while also protecting the privacy of the vehicle interior.

[0102] The technical solution provided by this disclosure adjusts the sun visor's light transmittance based on the real-time detected light intensity, ensuring that the light intensity is within a reasonable range that satisfies the shading requirement and does not obstruct the driver's vision. This improves vehicle safety and provides a better driving experience. Furthermore, the sun visor provided in this embodiment is made of a material with adjustable light transmittance, eliminating the need for additional equipment such as cameras. This reduces costs, simplifies control, and offers high operational reliability and a high cost-performance ratio.

[0103] The above mainly introduces the solution provided by the present disclosure from the perspective of the interaction between various devices or nodes. It is understandable that, in order to realize the above functions, each device or node includes a hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present invention.

[0104] FIG5 is a schematic diagram showing the components of a sun visor control device according to an embodiment of the present disclosure. As shown in FIG5 , the sun visor control device 50 includes a receiving module 501 and a processing module 502 .

[0105] In some embodiments, the receiving module 501 is used to obtain the light intensity of the sun visor. The processing module 502 is used to adjust the light transmittance of the sun visor according to the light intensity of the sun visor.

[0106] In some embodiments, the illumination intensity of the sun visor includes an inner illumination intensity, where the inner illumination intensity is the illumination intensity of light incident from the vehicle exterior toward the vehicle interior, detected on the side of the sun visor facing the vehicle interior. Processing module 502 is configured to: reduce the light transmittance of the sun visor if the inner illumination intensity is greater than a light intensity threshold; and maintain the light transmittance of the sun visor unchanged or increase the light transmittance of the sun visor if the inner illumination intensity is less than or equal to the light intensity threshold.

[0107] In some embodiments, processing module 502 is configured to: obtain an initial light transmittance of the sun visor upon activation; maintain the light transmittance of the sun visor unchanged if the initial light transmittance is a maximum value within an adjustable light transmittance range and the inner light intensity is less than or equal to a light intensity threshold; and increase the light transmittance of the sun visor if the initial light transmittance is a minimum value within the adjustable light transmittance range and the inner light intensity is less than or equal to the light intensity threshold.
