[0002] With the rapid development of society and the economy, cars have become an important means of transportation for families. However, there are also some problems in the use of cars. For example, on a sunny day, the sunlight can be very dazzling when the car is driven towards the sun. Similarly, at night, the high beams of other vehicles can be extremely blinding. These situations can affect the driver's normal driving and bring significant safety hazards. Therefore, traditional cars have an opaque sun visor above the driver's head. The driver needs to manually flip down and adjust the angle of the sun visor to block the light. However, this manual adjustment must be completed before the car is driven, otherwise it will affect the driver's driving. Summary of the Invention

[0003] Therefore, it is necessary to provide a sun visor control method, control device, storage medium, and sun visor to address the problem that drivers need to manually flip down and adjust the angle of the sun visor when using it, which makes it difficult to operate while driving.

When the sun shade body is in the first shading level, the sun shade body has a first light transmittance. When the sun shade body is in the second shading level, the sun shade body has a second light transmittance that is less than the first light transmittance.

[0012] The step of adjusting the light transmittance of the sunshade body according to the light parameters specifically includes:

[0013] If the current light intensity is greater than or equal to the first light intensity preset value and less than the second light intensity preset value, then the sunshade body is controlled to be in the first light-blocking position.

[0014] If the current light intensity is greater than or equal to the second light intensity preset value, the sunshade body is controlled to be in the second shading position;

[0015] The second preset light intensity value is greater than the first preset light intensity value.

[0016] In one embodiment, the first transmittance is 70% to 80%; the second transmittance is 55% to 65%.

[0017] In one embodiment, the sunshade body includes multiple sunshade areas, and each sunshade area has a light-transmitting state and a sun-shading state.

[0018] The step of adjusting the light transmittance of the sunshade body according to the light parameters specifically includes:

[0019] Based on the current incident angle of light and the eye position parameters, obtain the target shading area through which the light rays entering the driver's eyes pass;

[0021] In one embodiment, the sunshade body includes a first sunshade area, a second sunshade area, and a third sunshade area arranged sequentially from the inside out, and the first sunshade area, the second sunshade area, and the third sunshade area each have a light-transmitting state and a sun-shading state; the sunshade is preset with a manual operation mode and a manual operation button for sending manual control signals;

[0022] The control method further includes:

[0023] When the manual control signal is received for the first time, the sunshade body is controlled to enter the manual operation mode, and the first sunshade area, the second sunshade area and the third sunshade area are all controlled to be in the light-transmitting state.

[0024] When the manual control signal is received for the second time, the first shading area is controlled to be in the shading state.

[0025] When the manual control signal is received for the third time, the second shading area is controlled to be in the shading state.

[0026] When the manual control signal is received for the fourth time, the third shading area is controlled to be in the shading state;

[0027] When the manual control signal is received for the fifth time, the sunshade body is controlled to exit the manual operation mode, and the first sunshade area, the second sunshade area and the third sunshade area are all controlled to be in the light-transmitting state.

[0035] In the technical solution of this application, the sun visor has multiple preset working modes, each corresponding to different light parameter settings. Therefore, the sun visor senses the light parameters corresponding to the current working mode via a sensing device, and then the control device adjusts the shading rate of the sun visor body based on the light parameters sensed by the sensing device. This allows the sun visor to automatically adjust in real time, thereby reducing the impact of manual adjustment by the driver. It should be noted that in the sun visor control method proposed in this application, the light parameters obtained by the sensing device differ when the sun visor is in different working modes, making the adjustment of the light transmittance of the sun visor body more targeted and accurate.

[0051] With the rapid development of society and the economy, cars have become an important means of transportation for families. However, there are also some problems in the use of cars. For example, on a sunny day, the sunlight can be very dazzling when the car is driven towards the sun. Similarly, at night, the high beams of other vehicles can be extremely blinding. These situations can affect the driver's normal driving and bring significant safety hazards. Therefore, traditional cars have an opaque sun visor above the driver's head. The driver needs to manually flip down and adjust the angle of the sun visor to block the light. However, this manual adjustment must be completed before the car is driven, otherwise it will affect the driver's driving.

[0052] In view of this, this application proposes a sun visor, which aims to solve the problem that drivers need to manually flip down and adjust the angle of the sun visor when using it, making it difficult to operate while driving. Figure 1 This is a schematic diagram of the structure of an embodiment of the sunshade proposed in this application.

[0053] Please see Figure 1 The sun visor is used to install on the windshield 100 of a vehicle. The sun visor includes a sun visor body 1, a sensing device and a control device.

[0054] The sunshade body 1 is configured to adjust its light transmittance. A sensing device is mounted on the sunshade body 1 and is used to sense the illumination parameters of the sunshade body 1. A control device is electrically connected to the sunshade body 1 and the sensing device, respectively.

[0055] The sun visor body 1 of the sun visor proposed in this application is configured to adjust its own light transmittance. Since the sun visor body 1 is mounted on the windshield 100 of the vehicle, the intensity of light entering the passenger compartment can be adjusted by regulating the light transmittance of the sun visor body 1, thereby preventing strong light from affecting the driver's driving. Specifically, the sun visor senses light parameters through a sensing device, and the control device adjusts the light transmittance of the sun visor body 1 according to the light parameters, thus automatically adjusting the light transmittance of the sun visor in real time without requiring manual adjustment by the driver.

[0056] In some embodiments, the sensing device includes a light intensity sensor for sensing light intensity, a light angle sensing element for sensing the incident angle of light, and a human eye sensing element for sensing the driver's eye position parameters.

[0057] The sensing device detects light intensity using a light intensity sensor, the incident angle of light using a light angle sensor, and the driver's eye position parameters using an eye sensor. Higher light intensity means more glaring ambient light; therefore, when light intensity is high, the control device reduces the light transmittance of the sun visor body 1, thus reducing the amount of light entering the driver's cabin and preventing it from affecting the driver's driving. Conversely, when light intensity is low, the light transmittance of the sun visor body 1 can be appropriately increased to ensure a clear view for the driver.

[0058] By using the driver's eye position parameters and the incident angle of light, the control device can calculate the area through which the light entering the driver's eyes passes. Therefore, the control device can reduce the impact of light on the driver by adjusting the transmittance of the target area. Moreover, the area for adjusting the transmittance in this way is relatively small, which reduces the interference with the driver's vision.

[0059] Furthermore, sun visors are typically installed on vehicles, and these vehicles are equipped with GPS (Global Positioning System). The GPS can store the angle of incidence of sunlight in different regions at different times of day. Therefore, when the vehicle is in motion, the GPS can determine the current location, and the control device can then obtain the corresponding angle of incidence of sunlight for that region at that time based on the location information and the current time period, for subsequent control. In other words, the control device does not necessarily need a light angle sensor to detect the current angle of incidence of sunlight, or it can combine the current angle of incidence of sunlight sensed by the light angle sensor with the corresponding data stored in the GPS for control. Human eye sensing elements can be image acquisition devices, such as cameras and recorders. The control device can analyze the acquired images to determine the driver's eye position parameters.

[0060] This application also proposes a control device, which is the same as the control device described in the above sunshade. Figure 2 This is a schematic diagram of an embodiment of the control device proposed in this application. Please refer to... Figure 2The control device may include a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0061] In addition, this application also proposes a storage medium, which may be the memory 1005 in the control device as described above. The memory 1005 may include an operating system, a network communication module, a user interface module, and the steps of the sunshade control method described below.

[0062] Based on the above hardware structure, this invention proposes a method for controlling a sun visor. Figures 3 to 7 This is a flowchart illustrating the sunshade control method proposed in this application. Please refer to... Figure 3 The sunshade includes a sunshade body 1 with adjustable light transmittance, and the control method includes:

[0063] S10: Obtain the corresponding illumination parameters according to the current working mode of the sunshade. In the technical solution of this application, the sunshade has multiple preset working modes, and each working mode corresponds to different illumination parameter settings, thereby making the relationship between each working mode and the corresponding illumination parameters closer.

[0064] S20: Adjust the light transmittance of the sun visor body 1 according to the illumination parameters. After the sun visor senses the illumination parameters corresponding to the current working mode through the sensing device, the control device adjusts the shading rate of the sun visor body 1 based on the illumination parameters sensed by the sensing device. This allows the sun visor to automatically adjust in real time, thereby reducing the impact of manual adjustment by the driver on driving. It should be noted that in the sun visor control method proposed in this application, the illumination parameters obtained by the sensing device are different when the sun visor is in different working modes, making the adjustment of the light transmittance of the sun visor body 1 more targeted and accurate.

[0065] Please see Figure 4 In some embodiments, the sun visor's operating modes include an automatic mode and a personalized mode, and the illumination parameters include illumination intensity, illumination incident angle, and the driver's eye position parameters.

[0066] Step S10 specifically includes:

[0067] S11: If the sun visor is in automatic mode, the current light intensity is acquired. After the sensing device acquires the current light intensity parameter, the control device determines whether the current light is strong based on the current light intensity. When the light intensity is high, the control device can control the light transmittance of the sun visor body 1 to decrease, thereby reducing the light entering the driver's cabin and preventing the light from affecting the driver. When the light intensity is low, the control device can control the light transmittance of the sun visor body 1 to increase, thereby ensuring a clear field of vision for the driver.

[0068] S12: If the sun visor is in personalized mode, the current incident light angle and the driver's eye position parameters are obtained. The control device can obtain the propagation angle of light through the current incident light angle parameter, and then, based on the eye position parameter, the control device can determine the specific area on the sun visor body 1 through which the light entering the driver's eyes needs to pass. Therefore, the control device only needs to adjust the light transmittance of the specific area to avoid the light affecting the driver.

[0069] Please see Figure 5 In some embodiments, the sun shade body 1 is preset with a first shading level and a second shading level according to its own light transmittance. When the sun shade body 1 is in the first shading level, the sun shade body 1 has a first light transmittance; when the sun shade body 1 is in the second shading level, the sun shade body 1 has a second light transmittance that is less than the first light transmittance.

[0070] Step S20 specifically includes:

[0071] S21: If the current light intensity is greater than or equal to a first preset light intensity value and less than a second preset light intensity value, then the sun visor body 1 is controlled to be in the first shading position. The second preset light intensity value is greater than the first preset light intensity value. When the current light intensity is greater than or equal to the first preset light intensity value and less than the second preset light intensity value, it indicates that the light is relatively strong; therefore, the control device controls the sun visor body 1 to be in the first shading position. At this time, the sun visor body 1 has a first light transmittance, thereby blocking a small portion of light from entering the driver's cab and preventing the light from affecting the driver.

[0072] S22: If the current light intensity is greater than or equal to the second preset light intensity value, control the sun visor body 1 to be in the second shading position. When the current light intensity is greater than or equal to the second preset light intensity value, it indicates that the light is very strong, therefore the control device controls the sun visor body 1 to be in the second shading position. At this time, the sun visor body 1 has a second light transmittance, thereby enabling the sun visor body 1 to block more light from entering the cab and avoid affecting the driver. Compared to the first shading position, the light transmittance of the sun visor body 1 is lower when it is in the second shading position, thus blocking more light.

[0073] Specifically, the first light transmittance is 70% to 80%; the second light transmittance is 55% to 65%. That is, when the sun visor body 1 is in the first shading position, the light transmittance of the sun visor body 1 is 70% to 80%. When the sun visor body 1 is in the second shading position, the light transmittance of the sun visor body 1 is 55% to 65%. Of course, when the sun visor body 1 is in the first shading position, the light transmittance of the sun visor body 1 can also be other threshold ranges. Similarly, when the sun visor body 1 is in the second shading position, the light transmittance of the sun visor body 1 can also be other threshold ranges. These can be reset and adjusted according to usage requirements.

[0074] Furthermore, the specific values ​​of the first and second preset light intensity values ​​are not limited here; they can be set and adjusted according to usage requirements. Additionally, the sunshade body 1 can also have more preset light intensity values, thus providing more settings and allowing for more precise control of the light transmittance of the sunshade body 1.

[0075] Please see Figure 6 In some embodiments, the sunshade body 1 includes multiple sunshade areas, and each sunshade area has both a light-transmitting state and a sun-shading state. Step S20 specifically includes:

[0076] S23: Based on the current incident light angle and eye position parameters, obtain the target shading area through which the light rays entering the driver's eyes pass. The control device can obtain the propagation angle of the light rays using the current incident light angle parameters, and then, based on the eye position parameters, it can determine the target shading area through which the light rays entering the driver's eyes must pass. Therefore, the control device only needs to adjust the light transmittance of the target shading area to avoid the light affecting the driver. Specifically, the light rays can be considered as a light ray emitted from the driver's eyes along the current incident light angle, and the shading area through which the light ray passes is the target shading area.

[0077] S24: Control the target sunshade area to enter the sunshade state. The target sunshade area is smaller than the entire sun visor body 1. Therefore, controlling the target sunshade area to enter the sunshade state can either make the target sunshade area directly opaque, or simply reduce the light transmittance of the target sunshade area. When the target sunshade area directly enters the opaque state, because of its small area, it has less impact on the driver's visibility.

[0078] Please see Figure 7In some embodiments, the sun visor body 1 includes a first sun visor area, a second sun visor area, and a third sun visor area arranged sequentially from the inside out, and each of the first, second, and third sun visor areas has a light-transmitting state and a sun-shading state, respectively. The sun visor is preset with a manual operation mode and a manual control button for issuing manual control signals.

[0079] The control method further includes:

[0080] S31: When a manual control signal is received for the first time, the sun visor body 1 is controlled to enter manual operation mode, and the first, second, and third sun visor areas are all controlled to be in a light-transmitting state. When the control device receives a manual control signal for the first time, the sun visor enters manual operation mode, and at this time, the first, second, and third sun visor areas are reset to the light-transmitting state for subsequent driver adjustment. Specifically, the manual control buttons can be located in a position convenient for the driver to operate, such as on the steering wheel, and the light-transmitting state refers to a transparent state; when the first, second, and third sun visor areas are in the light-transmitting state, they do not have a sun-shading effect.

[0081] S32: When a manual control signal is received for the second time, the first sun visor area is put into sun-shading mode. When the control device receives a manual control signal for the second time, it indicates that the driver needs the sun visor for sun protection. At this time, the control device puts the first sun visor area into sun-shading mode, and the light transmittance decreases when the first sun visor area enters sun-shading mode. Since the first sun visor area is located in the middle of the sun visor, when the external light intensity is moderate, the first sun visor area can complete the sun protection when it enters sun-shading mode.

[0082] S33: When a manual control signal is received for the third time, the second sunshade area is put into a sunshade state. When the control device receives a manual control signal for the third time, it means that the driver believes that the sunshade effect needs to be increased. Therefore, the control device controls the second sunshade area to also be put into a sunshade state. At this time, the first sunshade area and the second sunshade area provide sunshade together, further improving the sunshade effect.

[0083] S34: When the manual control signal is received for the fourth time, the third sunshade area is put into a sunshade state. When the control device receives the manual control signal for the fourth time, it means that the driver believes that the sunshade effect needs to be increased. Therefore, the control device controls the third sunshade area to also be put into a sunshade state. At this time, the first, second, and third sunshade areas are all providing sunshade, further improving the sunshade effect.

[0084] S35: When the manual control signal is received for the fifth time, the sun visor body 1 is controlled to exit the manual operation mode, and the first, second, and third sun visor areas are all controlled to be in a light-transmitting state. In this embodiment, the sun visor body 1 is simply divided into a first, second, and third sun visor area. Therefore, when the first, second, and third sun visor areas are all in the sun-shading state, the sun visor's sun-shading effect has been maximized. When the control device receives the manual control signal for the fifth time, it indicates that the driver wants to exit the manual operation mode, so the control device controls the sun visor body 1 to exit the manual operation mode. To facilitate the subsequent adjustment of the sun visor in other modes, when the sun visor exits the manual operation mode, the first, second, and third sun visor areas are reset to the light-transmitting state.

[0085] It should be noted that the sun visor body 1 can be divided into more sun visor areas, thus giving the sun visor body 1 more settings and allowing for more precise control of different areas on the sun visor body 1 to enter the sun visor state.

[0086] Furthermore, the storage medium proposed in this application stores a control program for the sun visor, which, when executed by a processor, implements the steps of the sun visor control method as described in any of the above embodiments.

[0087] Similarly, this application proposes a control device, which includes a memory, a processor, and a control program for a sun visor stored in the memory and executable on the processor. The control program for the sun visor is configured to implement the steps of the sun visor control method as described in any of the preceding embodiments. Finally, the sun visor proposed in this application includes the aforementioned control device, thereby enabling the sun visor proposed in this application to perform the steps of the sun visor control method as described in any of the preceding embodiments under the control of the control device.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
