[0002] The existing car sun visor is a mechanical structure and can be manually adjusted by the driver. When the driver feels the glare of the sun, he needs to manually adjust the position of the sun visor, which will distract the driver's attention while driving and bring safety hazards. Moreover, when the sun shines directly on the driver's face, some drivers will ignore the sun visor and drive under the direct sunlight. The harmfulness is self-evident.

[0003] Therefore, if appropriate measures are not taken, it will cause serious harm to the driver's personal safety. It is necessary to develop a control method and system to avoid the above situation. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for intelligent control of a sun visor to address the deficiencies in the background technology, to remind the driver to open the sun visor when conditions are met and to enable the sun visor to open automatically through a voice wake-up function, thereby greatly improving driving safety and driving comfort.

[0005] To achieve the above object, the present invention provides the following technical solutions: A method for intelligently controlling a sun visor, applied in a vehicle, comprises the following steps: S1. acquiring a relative position of the sun relative to the vehicle; S2. determining whether the sun's irradiation light shines on the face of a driver of the vehicle at the relative position; S3. if the irradiation light shines on the driver's face, calculating an actual ratio of the area of ​​the driver's face irradiated by the irradiation light to the area of ​​the driver's face; S4. determining whether the actual ratio is greater than a standard ratio; S5. if the actual ratio is greater than a standard ratio, issuing a prompt message to remind the driver to open a sun visor in the vehicle.

[0006] Preferably, the step S1 includes the following steps: S101. Collecting a first image of the surrounding area of ​​the vehicle through a first camera; S102. Determining whether there is a highlighted area in the first image that cannot be identified as an object; S103. If there is a highlighted area in the first image that cannot be identified as an object, the positional relationship between the shooting direction of the first camera that takes the first image and the driving direction of the vehicle is the relative position.

[0007] Preferably, before determining whether the actual ratio is greater than a standard ratio, the following steps are also included: S301. Determine whether the irradiation light is irradiated on the eyes of the driver's face; S302. If the irradiation light is irradiated on the eyes of the driver's face, directly issue the prompt information.

[0008] Preferably, the step S2 comprises: S201. collecting a second image of the driver's face through a second camera; S202. determining whether the driver's face in the second image has the irradiating light.

[0009] Preferably, in step S202, the method for determining whether the driver's face in the second image is illuminated by the illumination light comprises the following steps: S2011. Acquire a brightness value of the driver's face in the second image; S2012. Determine whether the brightness value is greater than a standard value, wherein if the brightness value is greater than the standard value, it can be confirmed that the illumination light is illuminated on the driver's face.

[0010] Preferably, the method further includes the following steps: S5. determining whether the sun visor receives an opening instruction; S6. if the sun visor receives the opening instruction, the sun visor automatically opens to a position where the sun visor blocks the irradiated light.

[0011] To further achieve the above object, the present invention provides the following technical solutions: A sun visor intelligent control system is used in a vehicle, comprising: a sun visor, which is rotatably installed in the vehicle through a driving mechanism; a front camera, which is arranged on the vehicle and is used to obtain a relative position of the sun with respect to the vehicle; an in-vehicle camera, which is arranged in the vehicle and is used to obtain facial information of a driver in the vehicle; a processor, which is used to collect the relative position of the front camera and the facial information of the in-vehicle camera, and is also used to determine whether the sun's irradiation light shines on the face of a driver in the vehicle at the relative position. If the irradiation light shines on the driver's face, the processor calculates an actual ratio of the area of ​​the driver's face irradiated by the irradiation light to the area of ​​the driver's face, and the processor determines whether the actual ratio is greater than a standard ratio. If the actual ratio is greater than a standard ratio, the processor drives a voice broadcast module to issue a prompt message to remind the driver to open a sun visor in the vehicle.

[0012] Preferably, the front camera is also used to collect a first image around the vehicle. When the processor determines that there is a highlighted area in the first image that cannot be identified as an object, the positional relationship between the shooting direction of the front camera that takes the first image and the driving direction of the vehicle is the relative position.

[0013] Preferably, the in-vehicle camera is also used to collect a second image of the driver's face. After the in-vehicle camera collects the second image, the processor determines whether the driver's face in the second image has the illumination light. If the driver's face has the illumination light, the processor confirms that the illumination light is irradiated on the driver's face.

[0014] Preferably, the in-vehicle camera is also used to obtain a brightness value of the driver's face in the second image. After the in-vehicle camera obtains the brightness value, the processor determines whether the brightness value is greater than a standard value.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined. Example

[0021] See also Figure 1-Figure 3The present invention provides a sun visor intelligent control method, which is applied in a vehicle, specifically in a vehicle-mounted system of a vehicle, and mainly includes the following steps: S1. Acquire a relative position of the sun relative to the vehicle; S2. Determine whether the sun's irradiation light shines on the face of a driver of the vehicle at the relative position; S3. If the irradiation light shines on the driver's face, calculate an actual ratio of the area of ​​the driver's face illuminated by the irradiation light to the area of ​​the driver's face; S4. Determine whether the actual ratio is greater than a standard ratio; S5. If the actual ratio is greater than a standard ratio, issue a prompt message to remind the driver to open a sun visor in the vehicle. Through the above steps, the vehicle-mounted system obtains the relative position of the sun and the vehicle, and determines whether the actual ratio of the area of ​​the driver's face illuminated by the irradiated light to the area of ​​the driver's face exceeds the standard ratio, and when the actual ratio exceeds the standard ratio, a prompt message is promptly sent to the driver to remind the driver to open a sun visor in the vehicle, so that when the sunlight interferes with the driver's driving, the driver can be reminded to open the sun visor in time, which greatly improves the driving safety and the driving comfort of the driver. Furthermore, the following steps are also included: S6. Determine whether an opening instruction is collected; S7. If the opening instruction is collected, the sun visor automatically opens to the position of blocking the irradiated light, that is, the user can directly control the opening action of the sun visor in the form of voice wake-up, and the above functions can be achieved by setting a voice control module in the vehicle-mounted system, so that the overall control method is more intelligent and complete, optimizes the user experience, and has a high degree of automation. Secondly, regarding the driving method of the sun visor, a rotating motor can be installed, and the rotating motor is controlled by the voice control module. When the opening instruction is received, the sun visor is directly controlled to open to a position to block the irradiated light.

[0022] In detail, in step S1, the purpose of obtaining the relative position of the sun relative to the vehicle is mainly to obtain the specific position of the sun so as to facilitate the analysis of the relationship between the sun and the driver. For example, the sun may be in front of the vehicle, to the side, to the left, to the rear, or to the rear, etc. As a preferred embodiment, the acquisition method may include the following steps: S101. Collecting a first image of the vehicle periphery through a first camera; S102. Determining whether there is a highlight area in the first image that cannot be identified as an object; S103. If there is a highlight area in the first image that cannot be identified as an object, the positional relationship between the shooting direction of the first camera that shoots the first image and the driving direction of the vehicle is the relative position, thereby achieving the acquisition of the relative position. In addition, when the first camera shoots the first image, the direct sunlight from the sun will destroy the imaging of the first camera, resulting in a highlight area in the first image that cannot be identified as an object. The highlight area that cannot be identified as an object cannot be identified in the first image because its brightness value is the highest. When the above-mentioned highlight area that cannot be identified as an object is detected in the first image, it means that there is the sun in the area, and the relative position can be obtained in combination with the shooting direction of the first camera. For example, the first camera shoots a first image directly in front of the vehicle. If there is a highlight area that cannot be identified as an object in the first image, it proves that the sun is in front of the vehicle at this time, thereby confirming the relative position between the two, and executing the subsequent steps. For another example, the first camera shoots a first image to the left side of the vehicle. If there is a highlight area that cannot be identified as an object in the first image, it proves that the sun is on the left side of the vehicle at this time, thereby confirming the relative position between the two, and executing the subsequent steps. For another example, the first camera captures a first image toward the right side of the vehicle. If there is no highlighted area in the first image that cannot be identified as an object, it proves that the sun is not on the right side of the vehicle at this time, thereby confirming the relative position between the two, and no longer executing subsequent steps, and restarting step S1.

[0023] In addition, it should be noted that the further purpose of obtaining the relative position of the sun relative to the vehicle here is to control the opening mode and opening angle of the sun visor. For example, when a highlighted area that cannot be identified as an object appears in the first image taken by the first camera directly in front of the vehicle, it proves that the highlighted area in the first image is the position of the sun. At this time, the opening mode of the sun visor is to rotate forward and open, and the rotation angle of the sun visor can be adjusted according to the position of the highlighted area in the first image until the sun visor blocks the sunlight. That is, the sun visor is driven to rotate forward, and the rotation angle range is determined by the position of the highlighted area in the first image. The closer the position of the highlighted area in the first image is to the top of the first image, the larger the opening angle of the sun visor is, and the opening angle is within 0-180 degrees. Among them, as an optional embodiment, when the highlighted area in the first image is in the middle position of the first image, the sun visor can be driven to rotate to a vertical state at this time, and the sun visor in this state can be set as a reference position. When the highlighted area in the subsequent first image moves upward, the sun visor will follow and rotate forward. Secondly, assuming that the first camera captures a highlighted area on the left side of the vehicle that cannot be identified as an object, it proves that the sun is on the left side of the vehicle. At this time, the sun visor is opened by turning it toward the left, and the rotation angle of the sun visor can be adjusted according to the position of the highlighted area in the first image until the sun visor blocks the sunlight. The specific principle is the same as when the sun is in front of the vehicle, and will not be repeated here.

[0024] Next, in this embodiment, after completing the confirmation of the relative position of the sun with respect to the vehicle in step S1, step S2 is entered, in which the main purpose is to determine whether the sun's irradiation light is irradiated on the driver's face. In order to achieve the above purpose, the driver's face can be detected, for example: Figure 4 , including step S201 and step S202, wherein step S201 is to collect a second image of the driver's face through a second camera, and then step S202 is to determine whether the driver's face in the second image has the irradiation light. That is to say, here, based on image analysis technology or DMS technology (DMS usually refers to Driver Monitoring System, which is a technology used to monitor the driver's status, behavior and attention level), the second image taken by the second camera can be analyzed to determine whether the above-mentioned irradiation light exists in the second image. More specifically, the method for determining whether the driver's face in the second image has the irradiation light includes the following steps (based on image analysis technology): refer to Figure 5, S2011. Obtain a brightness value of the driver's face in the second image; S2012. Determine whether the brightness value is greater than a standard value, wherein if the brightness value is greater than the standard value, it can be confirmed that the irradiation light is irradiated on the driver's face. In other words, the standard value is the key to determine whether the irradiation light is irradiated on the driver's face. The setting rules of the standard value and the brightness value are both represented by pixel values. Generally speaking, the higher the pixel value, the higher the brightness of the image. Assuming that the second image imaged by the second camera is a grayscale image, its range is between 0-255. At this time, there are two methods for setting the standard value. The first method is to manually set a fixed value such as 155, 165, etc. If it is greater than the standard value, it is determined that the irradiation light is irradiated on the driver's face; the second method is that the second camera continuously collects the pixel values ​​of the irradiation light irradiating on the driver's face in different environments, and then takes the average value of these pixel values ​​to form the standard value to achieve the setting of the standard value.

[0025] Next, when the recognition of the irradiation light on the driver's face is completed, and if it is determined that the irradiation light is irradiated on the driver's face, it is necessary to analyze the irradiation light irradiated on the driver's face, and enter step S3 and step S4, that is, to judge the irradiation area of ​​the driver's face by the irradiation light. In detail, a second camera can be used to capture a second image of the driver's face, and then the area of ​​the driver's face irradiated by the light is counted. The statistical method here can use image recognition technology or DMS technology to mark the area on the driver's face where the brightness value is greater than the standard value, and then calculate the ratio of the marked area to the entire driver's face to obtain an actual ratio, and then compare the actual ratio with a standard ratio. If the actual ratio is greater than a standard ratio in step S5, a prompt message is issued to remind the driver to open a sun visor in the vehicle. Among them, the standard ratio can be 50%, 60% or 70% or even higher, mainly depending on the user's usage habits. If the user needs to open the sun visor when the driver's face is not exposed to much light, the standard ratio can be set to a relatively small value; if the user needs to open the sun visor when the driver's face is exposed to more light, the standard ratio can be set to a relatively large value.

[0026] In addition, before determining whether the actual ratio is greater than a standard ratio, the following steps are also included: Figure 6, S301. Determine whether the irradiation light is irradiated on the eyes of the driver's face; S302. If the irradiation light is irradiated on the eyes of the driver's face, directly issue the prompt information. That is to say, when it is detected that the eyes of the driver's face are irradiated by the irradiation light, the step of determining whether the actual ratio is greater than a standard ratio is skipped, and the prompt information is directly issued to remind the driver to open a sun visor in the vehicle. It should be noted that the principle of step S301 is: as mentioned above, the second image of the driver's face can be captured by a second camera through image recognition technology, and then the brightness value of the light irradiated on the eyes of the driver's face is counted. If the brightness value on the eyes of the driver's face is greater than the above standard value, it is determined that the irradiation light is irradiated on the eyes of the driver's face; secondly, assuming that a highlight area that cannot be identified as an object appears on the eyes of the driver's face, it also means that the irradiation light is irradiated on the eyes of the driver's face. It can be seen that the method of determining whether the irradiation light is irradiated on the eyes of the driver's face in step S301 can be realized by the above method.

[0027] Furthermore, in this embodiment, refer to Figure 7 , further comprising step S8. If the actual ratio is less than a standard ratio, it is determined whether the area of ​​the driver's face illuminated by the irradiation light accounts for at least 50% of the area of ​​the upper half of the driver's face. If it accounts for at least 50%, it means that most of the irradiation light is distributed near the eyes, and then step S9 is executed. A prompt message is issued to remind the driver to open a sun visor in the vehicle. Similarly, the method of steps S6-S7 can also be used, which will not be repeated here. Example

[0028] See also Figure 8The present invention also provides a sun visor intelligent control system 100, which is applied to a vehicle and includes a sun visor 1, a front camera 2, an in-vehicle camera 3 and a processor 4. The sun visor 1 is rotatably installed in the vehicle through a driving mechanism; the front camera 2 is arranged on the vehicle and is used to obtain a relative position of the sun relative to the vehicle; the in-vehicle camera 3 is arranged in the vehicle and is used to obtain facial information of a driver in the vehicle; the processor 4 is used to collect the relative position of the front camera 2 and the facial information of the in-vehicle camera 3, and is also used to determine whether the sun's irradiation light is irradiated on the face of a driver of the vehicle at the relative position. If the irradiation light is irradiated on the driver's face, the processor 4 calculates an actual ratio of the area of ​​the driver's face irradiated by the irradiation light to the area of ​​the driver's face, and the processor 4 determines whether the actual ratio is greater than a standard ratio. If the actual ratio is greater than a standard ratio, the processor 4 drives a voice broadcast module to send a prompt message to remind the driver to open a sun visor 1 in the vehicle. Furthermore, the processor 4 is also used to determine whether an opening instruction is collected. If the processor 4 collects the opening instruction, the processor 4 controls the sun visor 1 to automatically open to a position that blocks the irradiated light. In other words, the user can directly control the sun visor 1 to open by voice wake-up. The above functions can be achieved by setting a voice control module in the system, thereby making the overall control method more intelligent and complete, optimizing the user experience, and having a high degree of automation. Secondly, regarding the driving method of the sun visor 1, a rotating motor can be installed. The rotating motor is controlled by the voice control module. When the opening instruction is received, the sun visor 1 is directly controlled to open to a position that blocks the irradiated light. Among them, the front camera 2 is the first camera in Example 1, and the front camera 2 is also used to collect the first image around the vehicle. When the processor 4 determines that there is a highlighted area in the first image that cannot be identified as an object, the positional relationship between the shooting direction of the front camera 2 that takes the first image and the driving direction of the vehicle is the relative position. The above-mentioned processing steps, methods, principles and effects are the same as the processing steps, methods, principles and effects of the first camera in Example 1, and will not be repeated here.

[0029] Furthermore, the in-car camera 3 is the second camera in Example 1, and the in-car camera 3 is also used to collect a second image of the driver's face. When the in-car camera 3 collects the second image, the processor 4 determines whether the driver's face in the second image has the irradiation light. If the driver's face has the irradiation light, the processor 4 confirms that the irradiation light is irradiated on the driver's face. In addition, the in-car camera 3 is also used to obtain a brightness value of the driver's face in the second image. When the in-car camera 3 obtains the brightness value, the processor 4 determines whether the brightness value is greater than a standard value. If the brightness value is greater than the standard value, the processor 4 confirms that the irradiation light is irradiated on the driver's face. The above processing steps, methods, principles and effects are the same as the processing steps, methods, principles and effects of the second camera in Example 1, and are not repeated here.

[0030] To sum up, in combination with Example 1 and Example 2, through the above-mentioned technical means, the detection of the sun's radiation on the driver's face can be well realized, and the driver can be reminded to open the sun visor 1 when the conditions are met, and the sun visor 1 can also be automatically opened through the voice wake-up function. It is very convenient and fast, and the whole detection method is very intelligent. The radiation light on the driver's face is detected in real time, so that when the sun's radiation interferes with the driver's driving, the driver can be reminded to open the sun visor 1 in time, which greatly improves the driving safety and the driving comfort of the driver.
