[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0025] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0026] like Figure 1 As shown, an embodiment of the present application provides a sun visor control method, wherein a display screen is provided on the sun visor, and the method comprises:

[0027] Step 101, when it is detected that the sun visor is switched from a folded state to an open state, the ambient light intensity of the eye area of ​​the target occupant and the angle information corresponding to the light source in front of the vehicle are obtained.

[0028] The sun visor control method provided in the embodiment of the present application is applied to the sun visor controller. The sun visor can be rotatably fixed on the roof of the vehicle. The sun visor includes a folded state that fits the roof of the vehicle and an open state that forms a certain angle with the roof of the vehicle. Figure 2As shown, a display screen 201 is fixedly mounted on the side of the sun visor 200 close to the vehicle roof, and the display screen is closed by default when the sun visor is in a folded state. The display screen is used to display the playback content provided by the target playback source. For example, the display screen can be an extended screen of the vehicle multimedia host. The user can select the playback content from the multimedia host and select the display screen on the sun visor as the playback screen. The display screen can also be a screen with a separate host. The user can determine the playback content by operating the operation controls provided by the host. The user can also select the playback content to be projected onto the display screen through a mobile terminal. The user here refers to the target occupant. In addition, a camera can be set on the sun visor to display the image captured by the camera in real time through the display screen, so that the display screen can be used as a mirror.

[0029] In this embodiment, the sun visor controller can monitor the state switching of the sun visor. The sun visor provided in the embodiment of the present application can be a manual sun visor that needs to be manually operated, or an electric sun visor that is electrically opened by a driving component. When the sun visor is a manual sun visor, a displacement sensor can be installed on the sun visor to detect whether the state of the sun visor has changed. When the sun visor is an electric sun visor, the switch button of the sun visor can be monitored to detect whether the state of the sun visor has changed. When it is detected that the sun visor is switched from a folded state to an open state, it can be determined that the user has the intention to use the sun visor. At this time, the ambient light intensity of the eye area of ​​the target occupant and the angle information corresponding to the light source in front of the vehicle are obtained. The light source here generally refers to the sun, and it can also be a strong light turned on on the front vehicle or building. The target occupant refers to the occupant sitting on the seat opposite the sun visor.

[0030] Step 102 : When it is determined according to the angle information that the light source directly illuminates the eye area of ​​the target occupant and the ambient light intensity is greater than or equal to a preset threshold, control the sun visor to enter a sunshade mode.

[0031] Step 103 : When it is determined according to the angle information that the light source does not directly illuminate the eye area of ​​the target occupant, and / or the ambient light intensity is less than the preset threshold, control the sun visor to enter a multimedia mode.

[0032] Wherein, when the sun visor is in the sun shading mode, the display screen is in an off state, and when the sun visor is in the multimedia mode, the display screen is in an on state and displays the playback content provided by the target playback source.

[0033] After obtaining the ambient light intensity and the angle information of the light source, the sun visor controller can determine whether the ambient light intensity exceeds the preset threshold based on the ambient light intensity and the preset threshold, and determine whether the light source directly hits the occupant's eye position based on the angle information. If the ambient light intensity exceeds the preset threshold and the light source directly hits the eye area, it indicates that the user may open the sun visor for sun protection. In this case, the sun visor is controlled to enter the sun protection mode. If the ambient light intensity does not exceed the preset threshold and / or the light source does not directly hit the eye area, it indicates that the user may not open the sun visor for sun protection, but needs to use the display to watch film and television content. In this case, the sun visor is controlled to enter the multimedia mode, the display is turned on and displays the playback content provided by the target playback source. The target playback source here includes but is not limited to: an on-board multimedia host, a user's mobile terminal, a separate multimedia host on the sun visor, and a camera on the sun visor.

[0034] The embodiment of the present application obtains the ambient light intensity in the vehicle and the angle information corresponding to the light source in front of the vehicle when detecting that the sun visor is switched from a folded state to an open state, and predicts whether the actual intention of the user to open the sun visor is to shade the sun based on whether the ambient light intensity exceeds a preset threshold and whether the light source directly shines into the eyes of the occupants. If so, the sun visor enters a sun shading mode, otherwise it enters a multimedia mode, thereby eliminating the need for the user to manually open the display when they want to use it, thereby improving the user experience and the intelligence of the entire vehicle.

[0035] In an optional embodiment of the present application, after controlling the sun visor to enter the multimedia mode, the method further includes:

[0036] When it is detected that the sun visor is switched from the open state to the folded state, the display screen is controlled to be turned off.

[0037] After controlling the sun visor to enter the multimedia mode, the user can select the playback content corresponding to the display screen according to demand. When the embodiment of the present application detects that the state of the sun visor switches from an open state to a folded state, that is, when the user is not using the sun visor temporarily, the display screen is controlled to shut down, so that the display screen is in the off state when the sun visor is in the folded state.

[0038] The above-mentioned implementation scheme of the present application detects the state of the sun visor and turns off the display screen when the user folds the sun visor, thereby eliminating the need for the user to manually turn off the display screen before folding the display screen, thereby simplifying the user operation and further improving the user experience.

[0039] It should be noted that a switch for turning off the display screen is provided on the sun visor. When the user does not use the display screen but needs to use the sun visor for sun protection, the display screen can be manually turned off by the switch.

[0040] In an optional embodiment of the present application, the method further includes:

[0041] receiving a sun visor mode switching signal triggered by a user;

[0042] According to the sun visor mode switching signal, the sun visor is controlled to enter a multimedia mode or a sun visor mode.

[0043] Specifically, a mode switching button is provided on the sun visor, and the user can switch the mode of the sun visor through the mode switching button, from the sun visor mode to the multimedia mode, or from the multimedia mode to the sun visor mode. A voice control component can also be provided on the sun visor, and the user can switch the mode of the sun visor through voice control. When the user presses the mode switching button or outputs a mode switching voice command, the sun visor controller receives the sun visor mode switching signal, and controls the sun visor to enter the multimedia mode or the sun visor mode according to the sun visor mode switching signal.

[0044] The above implementation scheme of the present application receives a sun visor mode switching signal and controls the sun visor to switch modes, so that the user can independently control the mode of the sun visor.

[0045] In an optional embodiment of the present application, when obtaining the angle information corresponding to the light source in front of the vehicle, the angle information corresponding to the light source in front of the vehicle can be obtained by a light sensor installed at the front of the vehicle. Further, after obtaining the angle information corresponding to the light source in front of the vehicle by the light sensor installed at the front of the vehicle, the method further includes:

[0046] Acquiring first position information corresponding to the eye position of the target occupant;

[0047] Acquire second position information corresponding to the optical sensor;

[0048] calculating a horizontal distance between the optical sensor and an eye position of the target occupant according to the second position information and the first position information;

[0049] Calculating the vertical irradiation height of the light on the vertical plane where the eye position of the target occupant is located according to the angle information corresponding to the light source, the second position information, and the horizontal distance;

[0050] According to the first position information and the vertical irradiation height of the light, it is determined whether the light source directly irradiates the eye area of ​​the target occupant.

[0051] Specifically, after obtaining angle information corresponding to the light source in front of the vehicle through the optical sensor installed at the front of the vehicle, it is necessary to determine whether the light source directly hits the eye position of the occupant based on the angle information.

[0052] The following describes how to determine whether the light source is directly shining on the occupant's eyes.

[0053] Step 21, obtaining the first position information corresponding to the eye position of the target occupant. Specifically, the occupant may be photographed by a camera installed on the vehicle, the eye position of the occupant may be identified, and the first position information may be obtained. The first position information here may be the coordinate position (A1, B1, C1) corresponding to the eye position in the target coordinate system, and the target coordinate system has the longitudinal center line of the vehicle as the X axis, the transverse center line as the Y axis, and the vertical direction as the Z axis.

[0054] Step 22, obtaining the second position information corresponding to the optical sensor. Specifically, the second position information is known information and is pre-stored in a storage unit of the vehicle. The second position information here can be the coordinate position (A2, B2, C2) corresponding to the optical sensor position in the target coordinate system.

[0055] Step 23, calculating the horizontal distance between the optical sensor and the eyeball of the passenger in the front passenger seat according to the second position information and the first position information. Specifically, the horizontal distance L is equal to the absolute value of the difference between A1 and A2.

[0056] Step 24, calculate the vertical irradiation height of the light on the vertical plane where the occupant's eyeball is located according to the angle information corresponding to the light source, the second position information, and the horizontal distance. Specifically, the angle corresponding to the angle information is β, and the calculation formula of the vertical irradiation height of the light is as follows: H = C2-L*tanβ.

[0057] Step 25, determining whether the light source directly hits the eye position of the occupant based on the first position information and the vertical irradiation height of the light. Specifically, the height C1 in the first position information is compared with H. When the absolute value of the difference between C1 and H is less than a preset threshold, it is determined that the light source directly hits the eye position; otherwise, it is determined that the light source does not directly hit the eye position.

[0058] The above implementation scheme of the present application can determine whether the light source is directly shining on the eye position of the occupant through the first position information corresponding to the eye position, the second position information corresponding to the light sensor and the angle information corresponding to the light source, so as to facilitate the subsequent determination of the occupant's actual intention to open the sun visor based on the result, and then determine the sun visor mode.

[0059] In an optional embodiment of the present application, a camera is provided on the sun visor to control the sun visor to enter a multimedia mode, and the method further includes:

[0060] Obtaining the speed of the vehicle;

[0061] When the vehicle speed is less than or equal to a preset speed threshold, the camera is controlled to turn on, and the image captured by the camera is displayed on the display screen.

[0062] like Figure 2 As shown, a camera 202 can be provided on the sun visor 200 provided in the embodiment of the present application, and the display screen can display the image captured by the camera in real time, so the display screen can be used as a mirror. The embodiment of the present application controls the sun visor to enter the multimedia mode, including obtaining the speed of the vehicle. When the speed is less than a preset speed threshold, the preset speed threshold can be set to a speed between 5 and 10 km / h, that is, when the vehicle is stationary or the speed is extremely low, when the user opens the sun visor, it may be to use the mirror to put on makeup. At this time, the camera is turned on and the image captured by the camera is displayed on the display screen.

[0063] The above implementation scheme of the present application detects the vehicle speed and, when the vehicle speed is extremely low and the user opens the sun visor for not sun protection, it is determined that the user may need to use the mirror. At this time, the image captured by the camera is displayed on the display screen, thereby eliminating the need for the user to manually turn on the camera function, thereby improving the user experience.

[0064] It should be noted that the display screen in the embodiment of the present application may be a touch screen. When the display screen displays an image captured by a camera, the user may operate the touch screen to zoom in or out the image.

[0065] In an optional embodiment of the present application, a camera and a camera cover are provided on the sun visor. After controlling the sun visor to enter the multimedia mode, the method further includes:

[0066] When it is detected that the camera cover is switched from blocking the camera to not blocking the camera, the camera is controlled to be turned on, and an image captured by the camera is displayed on the display screen;

[0067] When it is detected that the camera cover is switched from not blocking the camera to blocking the camera, the camera is controlled to be turned off, and the playback content provided by the target playback source is displayed on the display screen.

[0068] like Figure 2 As shown, in the case where a camera 202 is provided on the sun visor 200 provided in the embodiment of the present application, a camera cover 203 can also be provided at the camera position, and the user can manually open or close the camera cover. After the display screen is turned on, when it is detected that the camera cover switches from blocking the camera to not blocking the camera, it indicates that the user has a need to use the camera. At this time, the camera is turned on and the image captured by the camera is displayed on the display screen.

[0069] It should be noted that the camera cover can be manually controlled or electrically controlled by a drive component.

[0070] The above implementation scheme of the present application determines whether the user needs to use the camera by detecting whether the camera cover blocks the camera, and then adjusts the corresponding display content of the display screen to display the image captured by the camera, without the user manually turning on the camera, thereby improving the user experience.

[0071] In an optional embodiment of the present application, the sun visor is provided with an LED lamp, and the method further comprises:

[0072] When the camera is turned on, detecting the ambient brightness in the vehicle;

[0073] When the ambient brightness is less than a preset brightness threshold, the LED light is controlled to be turned on.

[0074] like Figure 2 As shown, an LED light 204 can be provided on the sun visor 200 provided in the embodiment of the present application. When the camera is turned on, it indicates that the user has a need to use the camera. At this time, if the ambient brightness in the car is insufficient, that is, the ambient brightness is less than the preset brightness threshold, the camera will not be able to capture a clear image. At this time, the LED light can be turned on for fill light.

[0075] The above implementation scheme of the present application, by detecting the ambient brightness when the camera is turned on, can automatically turn on the LED light when the brightness in the car is insufficient, and use the LED light for fill light to improve the clarity of the image captured by the camera. There is no need for the user to manually turn on the LED light, thereby improving the intelligence of the sun visor and enhancing the user experience.

[0076] It should be noted that a voice control component can also be provided on the sun visor. When the user uses the sun visor, the voice control component can send voice commands to the sun visor controller. Specifically, the voice control component can recognize the voice commands output by the user and generate control commands. After generating the control commands, the control commands are sent to the sun visor controller, and the sun visor controller performs corresponding operations according to the control commands, such as opening and closing the display screen, opening and closing the camera, and opening and closing the LED lights.

[0077] The above introduces the sun visor control method provided in the embodiment of the present application. The following will introduce the sun visor control device provided in the embodiment of the present application in conjunction with the accompanying drawings.

[0099] Optionally, a camera and a camera cover are provided on the sun visor, and the device further comprises:

[0100] A fourth control module, configured to control the camera to turn on and display an image captured by the camera on the display screen when detecting that the camera cover switches from blocking the camera to not blocking the camera;

[0101] The fifth control module is used to control the camera to be turned off and display the playback content provided by the target playback source on the display screen when it is detected that the camera cover is switched from not blocking the camera to blocking the camera.

[0102] Optionally, the sun visor is provided with an LED lamp, and the device further comprises:

[0103] a detection module, configured to detect the current brightness inside the vehicle when the camera is turned on;

[0105] The sun visor control device provided by the present application obtains the ambient light intensity in the vehicle and the angle information corresponding to the light source in front of the vehicle when detecting that the sun visor is switched from a folded state to an open state, and based on whether the ambient light intensity exceeds a preset threshold and whether the light source directly shines into the eyes of the occupants, predicts whether the user's actual intention of opening the sun visor is to shade the sun. If so, the sun visor enters the sun visor mode, otherwise it enters the multimedia mode, thereby eliminating the need for the user to manually open the display when they want to use it, thereby improving the user experience and the intelligence of the entire vehicle.

[0106] An embodiment of the present application also provides an electronic device, including: a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, the various processes of the above-mentioned sun visor control method embodiment are implemented, and the same technical effect can be achieved. To avoid repetition, it will not be described here.

[0107] For example, Figure 4 A schematic diagram of the physical structure of an electronic device is shown.

[0108] like Figure 4 As shown, the electronic device may include: a processor (processor) 410, a communication interface (Communications Interface) 420, a memory (memory) 430 and a communication bus 440, wherein the processor 410, the communication interface 420, and the memory 430 communicate with each other through the communication bus 440. The processor 410 can call the logic instructions in the memory 430, and the processor 410 is used to perform the following steps: when it is detected that the sun visor is switched from a folded state to an open state, the ambient light intensity of the target occupant's eye area and the angle information corresponding to the light source in front of the vehicle are obtained; when it is determined according to the angle information that the light source directly illuminates the eye area of ​​the target occupant and the ambient light intensity is greater than or equal to a preset threshold, the sun visor is controlled to enter a sunshade mode; when it is determined according to the angle information that the light source does not directly illuminate the eye area of ​​the target occupant, and / or the ambient light intensity is less than the preset threshold, the sun visor is controlled to enter a multimedia mode; wherein, when the sun visor is in the sunshade mode, the display screen is in an off state, and when the sun visor is in the multimedia mode, the display screen is in an on state and displays the playback content provided by the target playback source.

[0109] In addition, the logic instructions in the above-mentioned memory 430 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on this understanding, the technical solution of the present application can be essentially or partly embodied in the form of a software product that contributes to the prior art, and the computer software product is stored in a storage medium, including several instructions to enable a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present application. The aforementioned storage medium includes: various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk.

[0110] An embodiment of the present application also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the various processes of the above-mentioned sun visor control method embodiment are implemented, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0111] An embodiment of the present application also provides a vehicle, which includes a sun visor and various processes of the above-mentioned sun visor control device embodiment, and can achieve the same technical effect. To avoid repetition, it will not be repeated here.

[0112] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
