[0020] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are some but not all of 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 the present application.

[0021] It should be understood that, throughout the specification, reference to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Therefore, appearances of “in one embodiment” or “in an embodiment” are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0022] In various embodiments of the present application, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes 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.

[0023] As shown in Figure 1 The present application provides a sun visor control method, which comprises the following steps:

[0024] In the case that an occupant is sitting on a target seat and a display screen on a sun visor corresponding to the target seat is in a closed state, a voice prompt message of whether to open a sun visor multimedia mode is output when it is detected that the backrest of the target seat is adjusted backward.

[0025] The sun visor control method provided by the present application is applied to a sun visor controller. A display screen is arranged on the sun visor in the present application. The display screen can play the playing content provided by a target playing source. For example, the display screen can be an expansion screen of a vehicle multimedia host. A user can select the 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. A user can determine the playing content by operating the operation control provided by the host. The user can also select the playing content by a mobile terminal and project the playing content onto the display screen.

[0026] The sun visor controller can monitor whether there is an occupant on the target seat, the state of the sun visor corresponding to the target seat, and whether the backrest of the target seat is adjusted backward. In a case where it is determined that there is an occupant on the target seat and the display screen on the sun visor corresponding to the target seat is in a closed state, the sun visor can be in a folded state or an unfolded state. When it is detected that the backrest of the target seat is adjusted backward, it indicates that the occupant sets the target seat to a preset rest mode (the seat backrest corresponding to the rest mode is unfolded to a preset angle) or the user manually adjusts the unfolded angle of the backrest to a larger angle. It is predicted that the occupant may have a demand for using the display screen on the sun visor. At this time, a voice prompt message of whether to open the sun visor multimedia mode is output.

[0027] Step 102, when the voice instruction message of confirming to open the sun visor multimedia mode sent by the occupant on the target seat is received, the sun visor is controlled to be unfolded, and the display screen on the sun visor is controlled to be turned on to display the playing content provided by the target playing source.

[0028] Specifically, when the backrest of the target seat is adjusted backward by the occupant, the sun visor controller will give a voice prompt, and the prompt content is whether to open the sun visor multimedia mode. At this time, the occupant can directly give a voice reply, and the sun visor controller can recognize the voice content output by the user. When the voice instruction message of confirming to open the sun visor multimedia mode sent by the occupant on the target seat is received, the sun visor is controlled to be unfolded, and the display screen is controlled to be turned on to display 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 mobile terminal of the user, a separate multimedia host on the sun visor, and a camera on the sun visor.

[0029] It should be noted that when the display screen on the sun visor is in a closed state, the state of the sun visor can be a folded state or an unfolded state. Therefore, in the step of controlling the sun visor to be unfolded, when the state of the sun visor is a folded state, the sun visor is controlled to be unfolded, and when the state of the sun visor is an unfolded state, the sun visor is controlled to remain in the unfolded state.

[0030] In the embodiments of the present application, when the target seat is occupied by an occupant and the display screen on the sun visor is in a closed state, when it is detected that the backrest of the target seat is adjusted backward, it is determined that the occupant may need to use the display screen, and a voice prompt message is output. When the voice instruction message of confirming to open the sun visor multimedia mode is received, the sun visor is controlled to be unfolded and the display screen is controlled to be turned on. Therefore, when the backrest of the seat is adjusted backward by the occupant, it is not necessary to manually turn on the display screen on the sun visor. The function linkage of the sun visor and the seat is realized, and the user experience is improved.

[0031] It should be noted that when the display screen on the sun visor is turned on, the method further comprises: acquiring the intensity of the in-vehicle ambient light; determining the target brightness corresponding to the display screen according to the intensity of the in-vehicle ambient light, and adjusting the brightness of the display screen to the target brightness.

[0032] Specifically, considering the change of the in-vehicle brightness during the driving of the vehicle, especially when entering and exiting the tunnel, the in-vehicle brightness will change greatly, so when the user uses the display screen on the sun visor, the in-vehicle ambient light intensity can be collected in real time through the light sensor, and the target brightness of the display screen is determined based on the real-time collected in-vehicle ambient light intensity, and the brightness of the display screen is adjusted to the target brightness, wherein the corresponding relationship between the in-vehicle ambient light intensity and the target brightness can be set in advance, so that the display screen brightness matching the real-time collected in-vehicle ambient light intensity can be determined based on the corresponding relationship. By adjusting the brightness of the display screen in real time, the automatic adjustment of the display brightness of the display screen is realized to adapt to the light intensity of the surrounding environment, without the need for manual adjustment by the user, thereby increasing the user experience. At the same time, it can also prevent excessive power consumption caused by a single brightness.

[0033] In an optional embodiment of the present application, after controlling the display screen on the sun visor to turn on, the method further comprises:

[0034] Controlling the headrest audio on the target seat to be turned on to play the audio content provided by the target playback source.

[0035] Specifically, the headrest audio is arranged at the position of the headrest of the target seat, and after controlling the display screen on the sun visor to turn on, the headrest audio is controlled to be turned on to play the audio content provided by the target playback source. It should be noted that the audio content played by the headrest audio and the content played by the display screen on the sun visor are matched with each other.

[0036] Since the headrest audio can create a super near-field sound area for the occupant, when the occupant on the target seat watches the playback content provided by the sun visor display, the corresponding audio content can be played through the headrest audio, so as to avoid affecting other occupants in the vehicle. Especially when the target seat is the front passenger seat, the use of the headrest audio can avoid affecting the driver.

[0037] The above-mentioned embodiments of the present application can make the occupant on the target seat listen to the audio content corresponding to the content played by the sun visor display through the headrest audio on the target seat, thereby avoiding affecting other occupants in the vehicle.

[0038] In an optional embodiment of the present application, the method further comprises:

[0039] When the target seat is occupied by an occupant and the sun visor corresponding to the target seat is in a folded state, an ambient light intensity of an eye region of a target occupant on the target seat and angle information corresponding to a light source in front of the vehicle are acquired;

[0040] 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 be unfolded.

[0041] Specifically, the basic function of the sun visor is sunshade, and the sun visor controller can detect whether the target seat is occupied by an occupant and the state of the sun visor. When the target seat is occupied by an occupant and the sun visor is in a folded state, the sun visor controller acquires the ambient light intensity of the eye region of the target occupant on the target seat and the angle information of the light source in front of the vehicle, and controls the sun visor to be unfolded automatically 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, so as to avoid the light source directly irradiating the eye position of the target occupant.

[0042] According to the embodiment of the present application, the angle information corresponding to the light source in front of the vehicle can be acquired by the light sensor installed on the front of the vehicle, and then the first position information corresponding to the eye position of the target occupant is acquired. Specifically, the eye position of the occupant can be identified by shooting the occupant through the camera installed on the vehicle, and then the first position information is obtained. The first position information can be the coordinate position (A1, B1, C1) corresponding to the eye position in the target coordinate system. The target coordinate system is a coordinate system with 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. The second position information corresponding to the light sensor is acquired. Specifically, the second position information is known information, which is stored in the storage unit of the vehicle in advance. The second position information can be the coordinate position (A2, B2, C2) corresponding to the position of the light sensor in the target coordinate system. According to the second position information and the first position information, the horizontal distance between the light sensor and the eyeball of the occupant on the co-driver seat is calculated. Specifically, the horizontal distance L is equal to the absolute value of the difference between A1 and A2. According to the angle information corresponding to the light source, the second position information, and the horizontal distance, the vertical irradiation height of the light ray on the vertical plane where the eyeball of the occupant is located is calculated. Specifically, the angle corresponding to the angle information is β, and the calculation formula of the vertical irradiation height of the light ray is as follows: H=C2-L*tanβ. According to the first position information and the vertical irradiation height of the light ray, it is determined whether the light source directly irradiates the eye position of the occupant. Specifically, the height C1 in the first position information and H are compared. When the absolute value of the difference between C1 and H is less than a preset height 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.

[0043] The above embodiments of the present application can detect the ambient light intensity of the eye area of the target passenger on the target seat and the angle information corresponding to the light source in front of the vehicle, so that the sun visor is automatically controlled to be deployed when the ambient light intensity is greater than or equal to a preset threshold and the light source directly irradiates the eye area of the target passenger, thereby eliminating the need for the user to manually open the sun visor and improving the intelligence of the sun visor.

[0044] In an optional embodiment of the present application, the control of the deployment of the sun visor includes:

[0045] obtaining a first deployment angle matched with the passenger on the target seat;

[0046] controlling the sun visor to be deployed to the first deployment angle.

[0047] In the embodiments of the present application, when it is determined that the passenger on the target seat uses the display screen on the sun visor, or when it is determined that the ambient light intensity of the eye position of the passenger on the target seat exceeds a preset threshold and is directly irradiated by a light source, the sun visor controller controls the sun visor to be deployed.

[0048] Specifically, the sun visor is in a deployed state between the maximum deployment angle and the minimum deployment angle, and the sun visor controller can pre-set a target angle (which is matched with the target seat in a default position, that is, when the target seat is in a default position and the sun visor is deployed to the target angle, the passenger can obtain the best viewing angle of the display screen on the sun visor) as the default angle of the deployment of the sun visor, and the sun visor controller can deploy the sun visor to the target angle when controlling the deployment of the sun visor.

[0049] In the embodiments of the present application, when the passenger on the target seat adjusts the backrest angle of the target seat or the front and rear position of the target seat, the sun visor deployed to the target angle cannot be adapted to the passenger, as shown in Figure 2 Therefore, when controlling the deployment of the sun visor 201, a first deployment angle matched with the passenger on the target seat 202 needs to be obtained, and the sun visor 201 is controlled to be deployed to the first deployment angle. Specifically, obtaining the first deployment angle matched with the passenger on the target seat includes: obtaining a first position corresponding to the eye of the passenger on the target seat; and determining the first deployment angle according to the first position and a second position corresponding to the sun visor.

[0050] When the first deployment angle is determined according to the first position and the second position, the angle of the sun visor perpendicular to the line connecting the first position and the second position can be determined as the first deployment angle, so that the viewing line of the passenger is perpendicular to the display screen on the sun visor.

[0051] The above-mentioned embodiments of the present application determine the first opening angle matched with the occupant when controlling the sun visor to open, and automatically open the sun visor to the first opening angle, so that the opening angle of the sun visor is matched with the eye position of the occupant, and the occupant is more comfortable when watching the playing content on the display screen of the sun visor, thereby improving the user experience.

[0052] It should be noted that, before the sun visor is controlled to open to the first opening angle, if the ambient light intensity of the eye area of the target occupant is greater than or equal to the preset threshold and the light source directly shines on the eye area of the target occupant, it indicates that the sun visor is opened to block the light, and after the sun visor is controlled to open to the first opening angle, the ambient light intensity of the eye area of the target occupant and whether the light source directly shines on the eye area need to be detected, if the ambient light intensity of the eye area is less than the preset threshold and / or the light source does not directly shine on the eye area, it indicates that the current opening angle of the sun visor can meet the sun-shading function of the sun visor, and can also meet the comfort of watching the playing content on the display screen of the sun visor. However, if the ambient light intensity of the eye area is still greater than the preset threshold and / or the light source still directly shines on the eye area, it indicates that the current opening angle of the sun visor can only meet the comfort of watching the playing content on the display screen of the sun visor, and cannot meet the sun-shading function of the sun visor, at this time, voice prompt information of whether to close the multimedia mode of the sun visor can be output, and when a voice instruction message of confirming to close the multimedia mode of the sun visor sent by the occupant on the target seat is received, the display screen of the sun visor is controlled to be closed, and the opening angle of the sun visor is adjusted so that the ambient light intensity of the eye area of the occupant is less than the preset threshold.

[0053] It should be further noted that the method provided by the embodiments of the present application further comprises: when the sun visor is opened to the multimedia mode based on the indication of the user, judging whether the ambient light intensity of the eye area of the target occupant on the target seat is greater than the preset threshold, and whether the light source in front of the vehicle directly shines on the eye area of the target occupant, and when the ambient light intensity of the eye area is greater than the preset threshold and the light source directly shines on the eye area of the target occupant, the opening angle of the sun visor is adjusted so that the ambient light intensity of the eye area of the occupant is less than the preset threshold, the playing content on the display screen is paused, and voice prompt information of whether to close the multimedia mode of the sun visor is output. That is, at this time, the sun-shading property of the sun visor needs to be met first.

[0054] In an optional embodiment of the present application, the method further comprises:

[0055] When the sun visor is in the opened state, if it is detected that the opening angle of the sun visor does not match the occupant on the target seat, a second opening angle matched with the occupant on the target seat is obtained.

[0056] The sun visor is controlled to adjust to the second opening angle.

[0057] Specifically, when the sun visor is in the unfolded state, the sun visor controller provided by the embodiment of the present application can detect whether the unfolded angle of the sun visor matches the occupant on the target seat at intervals of a preset time length, and when there is a mismatch, a second unfolded angle that matches the occupant on the target seat is obtained, and the sun visor is controlled to adjust to the second unfolded angle. For example, the above-mentioned mismatch may be that the occupant adjusts the unfolded angle of the seat back, the front and rear position of the seat, or the occupant on the target seat changes.

[0058] The above-mentioned embodiment of the present application detects whether the unfolded angle of the sun visor matches the occupant on the target seat, so that when there is a mismatch, the unfolded angle of the sun visor can be automatically adjusted in time to match the occupant, thereby improving the user experience.

[0059] In an optional embodiment of the present application, the method further comprises:

[0060] receiving a sun visor control instruction;

[0061] controlling the sun visor and the display screen on the sun visor according to the sun visor control instruction.

[0062] Specifically, the sun visor control buttons, such as the sun visor opening button, the sun visor closing button, the display screen opening button, and the display screen closing button, are arranged on the sun visor. The user can send a sun visor control instruction to the sun visor controller through the sun visor control buttons, and the sun visor controller can control the sun visor and the display screen on the sun visor according to the sun visor control instruction. The sun visor control instruction includes the sun visor opening instruction, the sun visor closing instruction, the display screen opening instruction, and the display screen closing instruction. In addition, a voice control component can also be arranged on the sun visor. The user can control the sun visor and the display screen through voice. The voice control component can recognize the instruction input by the user and send the recognition result to the sun visor controller.

[0063] The above-mentioned embodiment of the present application receives the sun visor control instruction to control the sun visor and the display screen on the sun visor, so that the user can independently control the sun visor.

[0064] In an optional embodiment of the present application, the method further comprises:

[0065] When the sun visor is in the unfolded state, the sun visor is controlled to switch to the folded state when it is detected that the occupant on the target seat leaves.

[0066] Specifically, when the sun visor is in the unfolded state, the sun visor controller detects whether there is an occupant on the target seat, and controls the sun visor to switch to the folded state when it is detected that the occupant on the target seat leaves.

[0067] The above embodiment of the present application can switch the sun visor from the unfolded state to the folded state when the occupant on the target seat leaves by detecting whether there is an occupant on the target seat, thereby realizing automatic folding of the sun visor, so that the user does not need to manually fold the sun visor.
