[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0024] It should be understood that the term “one embodiment” or “an embodiment” mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, “in one embodiment” or “in an embodiment” appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0025] In various embodiments of the present application, it should be understood that the size of the serial number of each process described below does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0026] As shown in Figure 1 The present application provides a sun visor control method, the sun visor is provided with a display screen, and the method comprises the following steps.

[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 region of the target occupant and the angle information corresponding to the light source in front of the vehicle are acquired.

[0028] The sun visor control method provided by the present application is applied to a sun visor controller, the sun visor is rotatably fixed on the roof of a vehicle, the sun visor comprises a folded state of being attached to the roof of the vehicle and an open state of being at a certain angle with the roof of the vehicle, and the sun visor control method comprises the following steps. Figure 2As shown, a display screen 201 is fixedly installed on the side of the sun visor 200 close to the vehicle roof, and the display screen is in a closed state by default when the sun visor is in a folded state. The display screen is used to display the playing content provided by a target playing source. For example, the display screen can be an expansion screen of a vehicle multimedia host, and a user can select playing content from the multimedia host and select the display screen on the sun visor as a playing screen. The display screen can also be a screen with a separate host, and a user can determine playing content by operating the operation control provided by the host, and the user can also select playing content to be projected onto the display screen through a mobile terminal. Here, the user refers to a target occupant. In addition, a camera can be arranged on the sun visor, and the display screen is used to display images captured by the camera in real time, 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 this embodiment can be a manual sun visor that needs to be manually operated, or an electric sun visor that is electrically opened by a driving assembly. 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 changes. When the sun visor is an electric sun visor, a switching button of the sun visor can be monitored to detect whether the state of the sun visor changes. When it is detected that the sun visor is switched from a folded state to an opened state, it can be determined that a user has the intention to use the sun visor. At this time, the ambient light intensity of the eye region of a target occupant and angle information corresponding to a light source in front of the vehicle are acquired. The light source generally refers to the sun, or a strong light lamp turned on on a front vehicle or a building, and the target occupant refers to an occupant sitting on a seat opposite to the sun visor.

[0030] In step 102, when it is determined according to the angle information that the light source directly irradiates the eye region 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.

[0031] In step 103, when it is determined according to the angle information that the light source does not directly irradiate the eye region 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.

[0032] In the sunshade mode, the display screen is in a shutdown state, and in the multimedia mode, the display screen is in a startup state and displays playing content provided by a target playing source.

[0033] After the sun visor controller obtains the ambient light intensity and the angle information of the light source, it can determine whether the ambient light intensity exceeds the preset threshold according to the ambient light intensity and the preset threshold, and determine whether the light source directly shines on the eye position of the occupant according to the angle information. If the ambient light intensity exceeds the preset threshold and the light source directly shines on the eye position, it indicates that the user's purpose of opening the sun visor is probably to block the sun, and at this time, the sun visor is controlled to enter the sun blocking mode. If the ambient light intensity does not exceed the preset threshold and / or the light source does not directly shine on the eye position, it indicates that the user's purpose of opening the sun visor is probably not to block the sun, but to use the display to watch video content, and at this time, the sun visor is controlled to enter the multimedia mode, the display is turned on and displays the playing content provided by the target playing source. The target playing source includes but is not limited to: a vehicle-mounted multimedia host, a user's mobile terminal, a separate multimedia host on the sun visor, and a camera on the sun visor.

[0034] In the embodiments of the present application, when it is detected that the sun visor is switched from the folded state to the open state, the ambient light intensity in the vehicle and the angle information corresponding to the light source in front of the vehicle are obtained, and whether the actual intention of the user to open the sun visor is to block the sun is predicted based on whether the ambient light intensity exceeds the preset threshold and whether the light source directly shines on the eyes of the occupant. If yes, the sun visor enters the sun blocking mode, otherwise, the sun visor enters the multimedia mode, so that the user does not need to manually turn on the display when he wants to use it, which improves the user experience and improves the intelligence of the vehicle.

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

[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 the sun visor is controlled to enter the multimedia mode, the user can select the playing content corresponding to the display screen according to the needs. In the embodiments of the present application, when it is detected that the state of the sun visor is switched from the open state to the folded state, that is, when the user temporarily does not use the sun visor, the display screen is controlled to be turned off, so that the display screen is in the off state when the sun visor is in the folded state.

[0038] In the above-mentioned embodiments of the present application, the state of the sun visor is detected, and the display screen is turned off when the user folds the sun visor, so that the user does not need to manually turn off the display screen before folding the display screen, which simplifies the user operation and further improves the user experience.

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

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

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

[0042] controlling the sun visor to enter a multimedia mode or a sunshade mode according to the sun visor mode switching signal.

[0043] Specifically, a mode switching button is arranged on the sun visor, and a user can switch the mode of the sun visor through the mode switching button, i.e., switching from a sunshade mode to a multimedia mode or switching from a multimedia mode to a sunshade mode. A voice control component can also be arranged on the sun visor, and a 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 instruction, the sun visor controller receives a sun visor mode switching signal, and controls the sun visor to enter a multimedia mode or a sunshade mode according to the sun visor mode switching signal.

[0044] The above-mentioned embodiments of the present application can control the sun visor to switch the mode by receiving a sun visor mode switching signal, so that a user can autonomously control the mode of the sun visor.

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

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

[0047] acquiring second position information corresponding to the light sensor;

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

[0049] calculating a light perpendicular irradiation height of a 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] determining whether the light source directly irradiates the eye region of the target occupant according to the first position information and the light perpendicular irradiation height.

[0051] Specifically, after the angle information corresponding to the light source in front of the vehicle is acquired through the light sensor installed at the front of the vehicle, it is necessary to determine whether the light source directly irradiates the eye position of the occupant according to the angle information.

[0052] How to determine whether the light source directly irradiates the eye position of the occupant will be introduced below.

[0053] In step 21, first position information corresponding to the eye position of the target passenger is obtained. Specifically, the passenger can be photographed by a camera installed on the vehicle, the eye position of the passenger is recognized, and then the first position information is obtained. The first position information can be a coordinate position (A1, B1, C1) corresponding to the eye position in a target coordinate system. The target coordinate system takes 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] In step 22, second position information corresponding to the light sensor is obtained. Specifically, the second position information is known information and is stored in the storage unit of the vehicle in advance. The second position information can be a coordinate position (A2, B2, C2) corresponding to the position of the light sensor in the target coordinate system.

[0055] In step 23, the horizontal distance between the light sensor and the eye of the passenger in the front passenger seat is calculated 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] In step 24, the vertical light irradiation height of the vertical plane where the passenger's eye is located is calculated 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 light irradiation height is as follows: H=C2-L*tanβ.

[0057] In step 25, it is determined whether the light source directly irradiates the eye position of the passenger according to the first position information and the vertical light irradiation height. 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 irradiates the eye position, otherwise, it is determined that the light source does not directly irradiate the eye position.

[0058] According to the above embodiments of the present application, 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 can be used to determine whether the light source directly irradiates the eye position of the passenger. This facilitates subsequent determination of the actual intention of the passenger to open the sun visor based on the result, and further determination of the sun visor mode.

[0059] In an optional embodiment of the present application, a camera is arranged on the sun visor, and the sun visor is controlled to enter the multimedia mode. The method further comprises:

[0060] obtaining the speed of the vehicle;

[0061] when the speed of the vehicle is less than or equal to a preset speed threshold, controlling the camera to be turned on and displaying the image collected by the camera on the display screen.

[0062] AsFigure 2 As shown, a camera 202 can be installed on the sun visor 200 provided in this application embodiment. 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 control of the sun visor to enter the multimedia mode in this application embodiment includes obtaining the vehicle speed. When the vehicle 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 vehicle speed is extremely low, when the user opens the sun visor, it may be to use the mirror for 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-described implementation scheme of this application detects vehicle speed. When the user opens the sun visor at extremely low speeds, but not for 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 screen, thus eliminating the need for the user to manually turn on the camera function and improving the user experience.

[0064] It should be noted that the display screen in this application embodiment can be a touch screen. When the display screen shows the image captured by the camera, the user can operate the touch screen to zoom in or out on the image.

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

[0066] When the camera cover is detected to switch from obscuring the camera to not obscuring the camera, the camera is turned on and the image captured by the camera is displayed on the screen.

[0067] When the camera cover is detected to switch from not obstructing the camera to obstructing the camera, the camera is controlled to turn 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 embodiment of this application, when a camera 202 is provided on the sunshade 200, a camera cover 203 can also be provided at the camera position. The user can manually open or close the camera cover. When the display screen is turned on, when it is detected that the camera cover has switched 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 controlled manually or electrically by a drive assembly.

[0070] The above-mentioned embodiments of the present application determine whether the user needs to use the camera by detecting whether the camera cover plate shields the camera, and then adjust the display content corresponding to the display screen to display the image collected 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, an LED lamp is arranged on the sun visor, 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, controlling the LED lamp to be turned on.

[0074] As shown in Figure 3 The sun visor 200 provided by the embodiments of the present application can be provided with an LED lamp 204. When the camera is turned on, it indicates that the user has the demand to use the camera. At this time, if the ambient brightness in the vehicle is insufficient, that is, the ambient brightness is less than a preset brightness threshold, the camera cannot capture a clear image. At this time, the LED lamp can be turned on to provide light compensation.

[0075] The above-mentioned embodiments of the present application detect the ambient brightness when the camera is turned on. In the case of insufficient brightness in the vehicle, the LED lamp can be automatically turned on to provide light compensation, thereby improving the clarity of the image captured by the camera. The user does not need to manually turn on the LED lamp, thereby improving the intelligence of the sun visor and the user experience.

[0076] It should be noted that the sun visor can also be provided with a voice control component. When the user uses the sun visor, the voice control component can be used to send a voice instruction to the sun visor controller. Specifically, the voice control component can recognize the voice instruction output by the user and generate a control instruction. After generating the control instruction, it is sent to the sun visor controller. The sun visor controller executes the corresponding operation according to the control instruction, for example, the opening and closing operation of the display screen, the opening and closing operation of the camera, and the opening and closing operation of the LED lamp.

[0077] The above describes the sun visor control method provided by the embodiments of the present application. The sun visor control device provided by the embodiments of the present application will be described below with reference to the accompanying drawings.
