[0034] At present, in order to solve the problem that the sun visor can block the driver's vision while providing a sunshade effect, the sun visor can be composed of an LCD display and a camera. Based on the sun visor, the shadow cast by the sun on the driver's face can be further determined using the image captured by the camera, and the area on the sun visor that affects the driver's vision can be calculated, so that the part used to project the sun onto the driver's eyes is darkened by adjusting the LCD display, and the rest of the panel remains transparent to provide a clear field of vision. However, the technical and cost challenges of this technical solution are high, and its practicality is low.

[0035] In view of this, an embodiment of the present disclosure provides a method for controlling a sun visor, the method comprising: obtaining the light intensity of the sun visor, and adjusting the light transmittance of the sun visor according to the light intensity of the sun visor. In this way, the light transmittance of the sun visor can be adjusted based on the light intensity inside and outside the sun visor detected in real time, so that the light transmittance is within a preset safety range, thereby improving the driving safety of the vehicle.

[0036] Figure 1 A schematic diagram of the structure of a sun visor provided in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the sun visor 100 includes a sun visor body 10 , a light sensor 20 and a controller 30 .

[0037] It should be noted that the sun visor 100 can usually be set at the front of the roof corresponding to the driver and / or co-driver, and is used to provide the driver and passengers with the function of shielding against dazzling light such as sunlight and strong 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.

[0038] The sun visor body 10 can be used to provide the driver and passengers with the function of shielding against dazzling light such as sunlight and strong light. In some embodiments, the sun visor body 10 can be provided with a makeup mirror / makeup mirror cover / makeup mirror light to facilitate the user to put on makeup and light. Alternatively, the sun visor body can also be provided with a strap / ticket clip to fix invoices, documents, business cards, etc.

[0039] In some embodiments, the sun visor body 10 may be made of a material with adjustable light transmittance. For example, the sun visor body 10 may be made of a glass material with adjustable light transmittance, such as electrically controlled atomized glass, and the sun visor body 10 may adjust the light transmittance by segmented adjustment, stepless adjustment, or regional adjustment.

[0040] In some embodiments, the sun visor body 10 may include a first sun visor and a second sun visor, the first sun visor being a front windshield of the vehicle made of a material with adjustable light transmittance, and the second sun visor being any one of a corner window glass, a rear windshield, a sunroof or a ceiling glass of the vehicle made of a material with adjustable light transmittance.

[0041] The light sensor 20 is disposed on the sun visor body 10 and is used to detect the light intensity of the sun visor.

[0042] In some embodiments, the light sensor 20 includes a first light sensor and / or a second light sensor. Figure 2 As shown, the light sensor on the sun visor 100 includes a first light sensor 21 and a second light sensor 22. The first light sensor 21 is disposed on a side surface of the sun visor body 10 facing the interior of the vehicle, and is used to detect the inner light intensity of the sun visor 100. The inner light intensity is the light 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 100 facing the interior of the vehicle. The second light sensor 22 is disposed on a side surface of the sun visor 100 facing the exterior of the vehicle, and is used to detect the outer light intensity of the sun visor 100. The outer light intensity is the light 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 100 facing the exterior of the vehicle. It should be understood that the sun visor 100 is in use.

[0043] The controller 30 can be connected to the light sensor 20 to control the sun visor 100. In some embodiments, the controller 30 can detect the light intensity of the sun visor through the light sensor, and adjust the light transmittance of the sun visor according to the light intensity of the sun visor. In some embodiments, the sun visor 100 includes a first sun visor and a second sun visor. The controller 30 can be specifically used to 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. And 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.

[0044] Understandably, Figure 1 The system architecture shown in the figure does not constitute a limitation on the embodiments of the present disclosure, and it may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0045] In some embodiments, the embodiments of the present application further provide a control device for a sun visor (hereinafter referred to as the control device in the embodiments of the present disclosure), and the control device is an electronic device with data processing capabilities. For example, the control device may be a controller of the sun visor 100. Alternatively, the control device may also be other electronic devices 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, a user device, etc. The embodiments of the present disclosure are not limited to this. The execution subject of the control method for the sun visor provided in the embodiments of the present disclosure is the control device.

[0046] The embodiments provided by the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0047] like Figure 3 As shown, an embodiment of the present disclosure provides a method for controlling a sun visor, the method comprising the following steps:

[0048] S101, obtaining the light intensity of the sun visor.

[0049] The light intensity of the sun visor may be the light intensity of the incident light on the sun visor from the outside of the vehicle to the inside of the vehicle.

[0050] In some embodiments, the light intensity of the visor includes an inside light intensity and / or an outside light intensity.

[0051] The inner light intensity of the sun visor is the light intensity of incident light from the outside of the vehicle to the inside of the vehicle detected on the surface of the sun visor facing the inside of the vehicle. It should be understood that the sun visor is in use.

[0052] In some embodiments, the inner light intensity can 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.

[0053] Exemplarily, the control device may obtain the first light intensity detected by at least one first light sensor, and determine the inner light intensity of the sun visor based on the at least one first light intensity. Exemplarily, the control device may determine the average value, maximum value, etc. of the at least one first light intensity as the inner light intensity of the sun visor.

[0054] In addition, the above-mentioned outside light intensity is the light intensity of incident light from the outside of the vehicle to the inside of the vehicle detected on the surface of the sun visor facing the outside of the vehicle. It should be understood that the sun visor is in use.

[0055] In some embodiments, the external light intensity can be determined based on at least one second light sensor disposed on the sun visor, wherein the second light sensor is disposed on a side surface of the sun visor facing the interior of the vehicle.

[0056] Exemplarily, the control device may obtain the second light intensity detected by at least one second light sensor, and determine the outer light intensity of the sun visor based on the at least one second light intensity. Exemplarily, the control device may determine the average value, maximum value, etc. of the at least one second light intensity as the outer light intensity of the sun visor.

[0057] In some embodiments, the control device may periodically obtain the light intensity of the sun visor at a preset frequency, wherein the preset frequency may be once per second, once per 60 seconds, once per 0.5 seconds, etc.

[0058] It should be noted that, when the user needs to use a sun visor to block the sunlight, the user can use the sun visor. For example, the user can adjust the sun visor to Figure 2 In the downwardly flipped state shown, the sun visor is in use. At this time, the control device can periodically obtain the light intensity of the sun visor at a preset frequency to update the current light intensity in time, and adjust the light transmittance of the sun visor in real time based on the obtained light intensity.

[0059] In some embodiments, Figure 4 As shown, the sun visor may include a plurality of sub-areas, and the control device may be configured to control the light intensity of each of the plurality of sub-areas of the sun visor.

[0060] Exemplarily, for any one sub-area, the illumination intensity of the sub-area may include the illumination intensity of incident light from the outside of the vehicle to the inside of the vehicle on the sub-area of ​​the sun visor. 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.

[0061] S102: adjusting the light transmittance of the sun visor according to the light intensity of the sun visor.

[0062] In some embodiments, when the vehicle is in driving state, the control device can adjust the light transmittance of the sun visor according to the light intensity of the sun visor.

[0063] In some embodiments, the control device may adjust the light transmittance of the sun visor according to 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 possible implementations:

[0064] 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.

[0065] Exemplarily, the control device may determine a comparison result between the inner 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. The light intensity threshold may be set based on an actual light intensity value that does not affect the driver's sight. In addition, the light intensity value may be pre-set in the sun visor or the control device, set by the user, or set in other possible ways.

[0066] 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.

[0067] In some embodiments, the control device may determine the difference between the current light transmittance of the sun visor and the light transmittance adjustment value as the adjusted light transmittance based on a preset light transmittance adjustment value. Alternatively, the control device may determine the adjusted light transmittance based on the light transmittance of the sun visor corresponding to the light intensity threshold and the current light transmittance of the sun visor.

[0068] It should be noted that the inner light intensity is detected based on the first light sensor on the side surface of the sun visor close to the interior of the vehicle. The first light sensor is closer to the driver, that is, the inner light intensity is closer to the light intensity of the incident light actually felt by the driver. Therefore, when the inner light intensity is greater than the light intensity threshold, it means that the current light intensity is too high, which will affect the driver's line of sight and further 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 felt by the driver and improve driving safety.

[0069] In another example, when the inner light intensity is less than or equal to a light intensity threshold, the control device maintains the light transmittance of the sun visor unchanged, or increases the light transmittance of the sun visor.

[0070] In some embodiments, the control device may obtain the initial light transmittance of the sun visor when it is activated, and adjust the light transmittance of the sun visor based on the initial light transmittance, the inner light intensity, and the light intensity threshold.

[0071] 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 adjustable light transmittance range and the inner light intensity is less than or equal to the light intensity threshold.

[0072] It should be noted that when the sun visor is activated, that is, when the sun visor just enters the above-mentioned use state, the default configured light transmittance may be the maximum value of the light transmittance adjustable range. Therefore, during the continued use of the sun visor, the light transmittance of the sun visor may gradually decrease from the maximum value, that is, the current light transmittance of the sun visor is a larger value. Therefore, when the inner light intensity is less than or equal to the light intensity threshold, the light transmittance of the sun visor can be kept unchanged, so as to maintain a larger light transmittance while meeting the user's sunshade needs, so as to avoid the sun visor blocking the driver's sight.

[0073] Alternatively, the control device may increase the light transmittance of the sun visor when the initial light transmittance is the minimum value of the adjustable light transmittance range and the inner light intensity is less than or equal to the light intensity threshold.

[0074] In some embodiments, the control device may determine the sum of the current light transmittance of the sun visor and the light transmittance adjustment value as the adjusted light transmittance based on the preset light transmittance adjustment value. Alternatively, the control device may determine the increased light transmittance based on the light transmittance of the sun visor corresponding to the light intensity threshold and the current light transmittance of the sun visor.

[0075] It should be noted that when the sun visor is activated, that is, when the sun visor just enters the above-mentioned use state, the default configured light transmittance may be the minimum value of the light transmittance adjustable range. Therefore, during the continued use of the sun visor, the light transmittance of the sun visor may gradually increase from the minimum value, that is, the current light transmittance of the sun visor is a small value, and then when the inner light intensity is less than or equal to the light intensity threshold, the light transmittance of the sun visor can be increased to maintain a large light transmittance while meeting the user's sunshade needs, so as to avoid the sun visor blocking the driver's vision.

[0076] In some embodiments, the control device may also reacquire the inner light intensity of the sun visor after adjusting the light transmittance of the sun visor, and adjust the light transmittance of the sun visor according to the reacquired inner light intensity of the sun visor. It should be understood that the control device may reacquire the inner light intensity of the sun visor and adjust the light transmittance of the sun visor multiple times so that the inner light intensity of the sun visor meets the limit of the light intensity threshold.

[0077] Implementation method 2: The illumination intensity of the sun visor includes the illumination intensity of the outer side. The control device adjusts the illumination intensity of the sun visor according to the illumination intensity of the outer side of the sun visor.

[0078] Exemplarily, the control device may determine a comparison result between the outer side illumination intensity of the sun visor and the illumination intensity threshold, and adjust the light transmittance of the sun visor based on the comparison result. In some embodiments, the illumination intensity threshold corresponding to the outer side illumination intensity may be equal to the illumination intensity threshold corresponding to the inner side illumination intensity, or the illumination intensity threshold corresponding to the outer side illumination intensity may be different from the illumination intensity threshold corresponding to the inner side illumination intensity.

[0079] 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.

[0080] In some embodiments, the control device may determine the difference between the current light transmittance of the sun visor and the light transmittance adjustment value as the adjusted light transmittance based on a preset light transmittance adjustment value. Alternatively, the control device may determine the adjusted light transmittance based on the light transmittance of the sun visor corresponding to the light intensity threshold and the current light transmittance of the sun visor.

[0081] It should be noted that when the outside light intensity is greater than the light intensity threshold, it means 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 felt by the driver and improve driving safety.

[0082] 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.

[0083] In some embodiments, the control device may determine the sum of the current light transmittance of the sun visor and the light transmittance adjustment value as the adjusted light transmittance based on the preset light transmittance adjustment value. Alternatively, the control device may determine the increased light transmittance based on the light transmittance of the sun visor corresponding to the light intensity threshold and the current light transmittance of the sun visor.

[0084] 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.

[0085] In some embodiments, the control device may further reacquire the outer light intensity of the sun visor after adjusting the light transmittance of the sun visor, and adjust the light transmittance of the sun visor according to the reacquired outer light intensity of the sun visor. It should be understood that the control device may reacquire the outer light intensity of the sun visor and adjust the light transmittance of the sun visor multiple times so that the outer light intensity of the sun visor meets the limit of the light intensity threshold.

[0086] In implementation mode 3, the light intensity of the sun visor includes the inner light intensity and the outer light intensity. The control device can adjust the light transmittance of the sun visor according to the inner light intensity and the outer light intensity of the sun visor.

[0087] 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 light transmittance of the sun visor based on the two comparison results obtained.

[0088] In one example, the control device reduces the light transmittance of the sun visor when both the outer side light intensity and the inner side light intensity are greater than the light intensity threshold.

[0089] Among them, the specific process of reducing the light transmittance of the sun visor can refer to the relevant description in the above-mentioned implementation method 1, and will not be repeated here.

[0090] In another example, the control device increases the light transmittance of the sun visor when the outer side light intensity and the inner side light intensity are both less than or equal to the light intensity threshold.

[0091] Among them, the specific process of increasing the light transmittance of the sun visor can refer to the relevant description in the above-mentioned implementation method 1, and will not be repeated here.

[0092] In another example, the control device maintains the light transmittance of the sun visor unchanged, or increases the light transmittance of the sun visor when the outer side light intensity is greater than the light intensity threshold and the inner side light intensity is less than or equal to the light intensity threshold.

[0093] It should be noted that, since the outer light intensity is detected based on the second light sensor on the side surface of the sun visor close to the outside of the vehicle, the inner light intensity is detected based on the first light sensor on the side surface of the sun visor close to the inside of the vehicle. The second light sensor is located closer to the vehicle environment, and the first light sensor is located closer to the driver. Therefore, the outer light intensity may be greater than the inner light intensity, and the inner light intensity is closer to the light intensity of the incident light actually felt by the driver. Therefore, when 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, it means that the current light transmittance of the sun visor meets the user's shading needs, and thus. The control device can keep the light transmittance of the sun visor unchanged, or increase the light transmittance of the sun visor.

[0094] 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 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.

[0095] 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.

[0096] In some embodiments, the control device may also reacquire the inner light intensity and the outer light intensity of the sun visor after adjusting the light transmittance of the sun visor, and adjust the light transmittance of the sun visor according to the reacquired inner light intensity and the outer light intensity of the sun visor. It should be understood that the control device may reacquire the inner light intensity and the outer light intensity of the sun visor multiple times and adjust the light transmittance of the sun visor so that the inner light intensity and the outer light intensity of the sun visor meet the light intensity threshold limit.

[0097] In some embodiments, when the sun visor includes multiple sub-areas, the control device can adjust the light transmittance of each sub-area of ​​the sun visor according to the light intensity of each sub-area of ​​the sun visor. Exemplarily, for any sub-area of ​​the sun visor, the control device can adjust the light transmittance of the sub-area of ​​the sun visor based on the method shown in the above implementation mode 1, implementation mode 2 or implementation mode 3, which will not be repeated here.

[0098] In a possible implementation, the sun visor is arranged on the front windshield of the vehicle.

[0099] In another possible implementation, the sun visor includes a first sun visor and a second sun visor, the first sun visor is a front windshield of the vehicle made of a material with adjustable light transmittance, and the second sun visor is any one of the corner window glass, rear windshield, sunroof or ceiling glass of the vehicle made of a material with adjustable light transmittance.

[0100] 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.

[0101] Exemplarily, the first illumination intensity threshold may be set based on an actual illumination intensity value that does not affect the driver's sight. The second illumination intensity threshold may be set based on an illumination intensity value that satisfies the comfort of passengers in the vehicle. In some embodiments, the value of the first illumination intensity threshold may be equal to the second illumination intensity threshold. Alternatively, the value of the first illumination intensity threshold may also be equal to the second illumination intensity threshold.

[0102] Among them, 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, combined with the method shown in, for example, the above-mentioned implementation mode 1, implementation mode 2 or implementation mode 3. And 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, combined with, for example, the method shown in, for example, the above-mentioned implementation mode 1, implementation mode 2 or implementation mode 3.

[0103] 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 light transmittance of the entire glass at various positions can be intelligently controlled to improve the vehicle's riding experience.

[0104] 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 avoid the sun visors blocking the driver's sight.

[0105] 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.

[0106] 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.
