[0008] In one embodiment, the step S3 also includes: if the real-time light intensity of the light source is greater than or equal to a preset light intensity threshold, and the first angle is greater than or equal to the second angle, then generating feedback information requesting adjustment of the sun visor; if the real-time light intensity of the light source is less than the light intensity threshold, and the first angle is less than the second angle, then generating feedback information not requesting adjustment of the sun visor.

[0009] In one embodiment, the step S4 also includes: in response to the feedback information of not requesting to adjust the sun visor, keeping the current state of the sun visor unchanged; in response to the feedback information of requesting to adjust the sun visor, determining the target position of the sun visor according to the difference between the first angle and the second angle.

[0010] In one embodiment, step S5 also includes: during the automatic adjustment, in response to receiving an interrupt adjustment instruction, suppressing the automatic adjustment, and confirming through the central control unit of the car whether to turn off the automatic adjustment function; if it is confirmed that the automatic adjustment function is turned off, turning off the automatic adjustment function and keeping the automatic adjustment state suppressed until the next power-on cycle of the car; if it is confirmed that the automatic adjustment function is not turned off, keeping the automatic adjustment function on and keeping the automatic adjustment state suppressed until the next power-on cycle of the car.

[0011] The second aspect of the present invention provides a car sun visor adjustment system, comprising a light tracking module, a light sensor, a camera, a controller and a sun visor, wherein the light tracking module is used to receive light from a light source outside the vehicle and determine the light source position of the light source according to the transmission path of the light, the light sensor is used to obtain the real-time light intensity of the light source, the camera is used to identify and obtain the eye position of the driver in the vehicle, the controller is communicatively connected with the light tracking module, the light sensor, the camera and the sun visor, and the controller is used to process and analyze information according to a predetermined program and algorithm to accurately control the position adjustment of the sun visor.

[0027] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0028] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0029] In daily driving, when a car enters a high-brightness environment, the driver's field of vision will be affected by the strong sunlight or other strong ambient light. In order to overcome the impact of strong sunlight or other strong ambient light on the driver's field of vision and ensure driving safety, according to the inventor's understanding, most of the car sun visors on the market currently require the driver to manually adjust to block light. However, when the driver manually adjusts the sun visor during driving, on the one hand, it will produce a single-handed steering wheel action, and on the other hand, it will distract the driver, which not only poses certain safety hazards, but also fails to make the sun visor reach the ideal expected position.

[0030] The inventors also learned that some automobile manufacturers monitor the changes in the driver's pupils, the direction of vehicle travel, etc. to determine the impact of light on the driver, and automatically adjust the position of the sun visor based on these impacts. However, on the one hand, due to the differences in pupil size and sensitivity to light of each person, and the presence of a large number of working conditions that cause the driver's pupils to change, such as entering and exiting tunnels, it is objectively impossible to truly and effectively determine the impact of light on the driver, and there is a problem of high-frequency false triggering of the sun visor action; on the other hand, with the change in latitude, for determining the direction of vehicle travel based on GPS to determine the impact of light on the driver, since the direction and angle of sunlight will change, it is objectively impossible to reflect the true impact of light on the driver.

[0031] In order to solve the problem of inaccurate judgment of the real impact of light on the driver in the above solution and improve the comfort and safety of the driver, it is necessary to improve the adjustment of the car sun visor.

[0032] Figure 1 A flow chart of a method for adjusting a car sun visor according to an embodiment of the present invention is shown; Figure 2 Shows Figure 1 The calculation principle diagram of the first angle and the second angle in the automobile sun visor adjustment method shown; Figure 3 Shows Figure 1 The control flow chart of the automobile sun visor adjustment method shown; Figure 4 A structural framework diagram of a vehicle sun visor adjustment system according to another embodiment of the present invention is shown.

[0033] See also Figure 1 The embodiment of the first aspect of the present invention provides a method for adjusting a car sun visor, which is applied to a car sun visor adjustment system, wherein the car sun visor adjustment system includes at least one sun visor, which is convenient for shielding the sunlight outside the vehicle and preventing the sunlight from directly shining into the driver's eyes, thereby improving driving comfort and safety. In some embodiments, in accordance with the requirements of relevant laws and regulations, the sun visor can also absorb and reflect heat from the sunlight, thereby slowing down the rise in temperature inside the vehicle to a certain extent, improving the comfort of the vehicle environment, and extending the service life of items inside the vehicle.

[0034] The automobile sun visor adjustment method comprises the following steps:

[0035] S1, obtaining the light source position of the light source outside the vehicle, the real-time light intensity of the light source, and the eye position of the driver inside the vehicle;

[0036] S2, calculating a first angle between a line between the light source position and the front windshield of the car relative to the vertical direction, and a second angle between a line between the driver's eye position and the front windshield relative to the vertical direction, and then comparing the first angle with the second angle;

[0037] S3, generating feedback information according to the real-time illumination intensity of the light source and the comparison result between the first angle and the second angle;

[0038] S4, judging whether the sun visor of the vehicle should be adjusted according to the feedback information, and if so, determining a target position of the sun visor according to the first angle and the second angle;

[0039] S5. Automatically adjust the position of the sun visor according to the target position.

[0040] It should be noted that in S1, the light source position of the light source outside the vehicle, the real-time light intensity of the light source, and the eye position of the driver inside the vehicle are obtained based on the driver's confirmation and permission. The driver's confirmation and permission can be asked for confirmation every time the driver enters the vehicle, or the driver can confirm and permit through the vehicle terminal or mobile terminal to continuously obtain relevant information.

[0041] In this embodiment, specifically, step S1 also includes: obtaining the light source position of the external light source through the light tracking module, obtaining the real-time light intensity of the light source through the light sensor, and obtaining the eye position of the driver in the car through the camera, wherein the light tracking module is used to receive the light from the external light source, and determine the light source position of the external light source according to the light transmission path of the external light source; the light sensor is used to monitor the real-time luminous flux of the external light source, and determine the real and real-time light intensity according to the luminous flux of the light emitted by the external light source; the camera is used to collect eye image data of the driver in the car, and identify the driver's eye area based on the collected eye image data to determine the driver's eye position.

[0042] like Figure 2As shown, in step S2, according to the light source position and the driver's eye position obtained in step S1, the first angle between the light source position and the front windshield relative to the vertical direction can refer to the angle between the center position of the light source and the top edge of the front windshield relative to the vertical direction of the ground, and the first angle can be recorded as α1; the second angle between the driver's eye position and the front windshield relative to the vertical direction can refer to the angle between the center position of the driver's eyeball and the top edge of the front windshield relative to the vertical direction of the ground, and the second angle can be recorded as α2. In this way, the data of the first angle α1 and the second angle α2 are obtained through the predetermined program and algorithm in the controller of the sun visor adjustment system, which is beneficial to accurately judge the influence of the light of the external light source on the driver's eyes and driving behavior in step S3. It should be noted that the front windshield mentioned here refers to the rectifying protection component made of transparent material in front of the driver's seat. Specifically, the front windshield is generally made of multiple layers of plexiglass inlaid on a frame, which has sufficient strength to protect the driver from airflow and external impact objects; and has sufficient transparency to provide the driver with a clear field of vision.

[0043] Furthermore, in order to ensure that the influence of the light from the external light source on the driver's eyes can be accurately determined, step S2 also includes: before calculating the first angle and the second angle, confirm whether the line connecting the light source position and the front windshield intersects with the line connecting the driver's eye position and the front windshield; when the line connecting the light source position and the front windshield intersects with the line connecting the driver's eye position and the front windshield, start calculating the first angle and the second angle. In the spatial coordinate system, preferably, the intersection point where the line connecting the light source position and the front windshield intersects with the line connecting the driver's eye position and the front windshield is in a plane perpendicular to the line connecting the driver's eyes, that is, the top edge of the front windshield directly in front of the driver's seat in the vehicle is the main reference area.

[0044] Furthermore, step S3 also includes: if the real-time illumination intensity of the light source is greater than or equal to the preset illumination intensity threshold, and the first angle is greater than or equal to the second angle, then feedback information requesting adjustment of the sun visor is generated; if the real-time illumination intensity of the light source is less than the illumination intensity threshold, and the first angle is less than the second angle, then feedback information not requesting adjustment of the sun visor is generated. It should be noted that the illumination intensity threshold mentioned here may refer to 4500lux, and the feedback information may refer to the flag that the current ambient light affects the driver's safe driving. Specifically, the flag that the current ambient light affects the driver's safe driving may be LightAffectsArv=0 and LightAffectsArv=1, wherein when LightAffectsArv=0, it indicates that the current ambient light does not affect the driver's safe driving, and the feedback information is not requesting adjustment of the sun visor; when LightAffectsArv=1, it indicates that the current ambient light affects the driver's safe driving, and the feedback information is requesting adjustment of the sun visor.

[0045] Further, step S4 also includes: in response to feedback information that does not request adjustment of the sun visor, keeping the current state of the sun visor unchanged; in response to feedback information that requests adjustment of the sun visor, determining the target position of the sun visor according to the difference between the first angle and the second angle. Specifically, when the flag bit is LightAffectsArv=0, keeping the current state of the sun visor unchanged; when the flag bit is LightAffectsArv=1, calculating the difference between the first angle and the second angle, and calibrating or determining the target position of the sun visor according to the difference.

[0046] like Figure 3 As shown, in order to ensure that the manual adjustment of the driver's subjective will will not be affected during the automatic adjustment of the sun visor, in this embodiment, step S5 also includes: during the automatic adjustment period, in response to receiving the interruption adjustment instruction, suppressing the automatic adjustment, and confirming whether to turn off the automatic adjustment function through the central control unit of the car; if it is confirmed to turn off the automatic adjustment function, then turn off the automatic adjustment function and keep the automatic adjustment state suppressed until the next power-on cycle of the car; if it is confirmed that the automatic adjustment function is not turned off, then keep the automatic adjustment function turned on and keep the automatic adjustment state suppressed until the next power-on cycle of the car. Specifically, when the position state of the automatic adjustment sun visor is interrupted by the driver's manual control, the automatic adjustment state is first suppressed, and at the same time responds to the driver's manual control action, and then a pop-up window is displayed on the central control screen of the car to remind "whether to turn off the automatic adjustment function". If the driver chooses yes, the automatic adjustment function is turned off and the automatic adjustment state is suppressed until the next power-on cycle of the car; if the driver chooses no, the automatic adjustment function is kept on and the automatic adjustment state is suppressed until the next power-on cycle of the car. It should be noted that when the next power-on cycle of the car is turned on, the instruction to suppress the automatic adjustment state is cleared.

[0047] The second aspect of the present invention provides a vehicle sun visor adjustment system, see Figure 4 The system includes a light tracing module, a light sensor, a camera, a controller and a sun visor, wherein the light tracing module is used to receive light and determine the light source position of an external light source according to the light transmission path, the light sensor is used to obtain the real-time light intensity of the light source, the camera is used to identify and obtain the eye position of the driver in the vehicle, the controller is communicatively connected with the light tracing module, the light sensor, the camera and the sun visor, and the controller is used to process and analyze information according to a predetermined program and algorithm to accurately control the position adjustment of the sun visor, so that the system has the characteristics of being able to accurately judge the real impact of light on the driver and adaptively adjust the position of the sun visor.

[0048] Furthermore, in order to ensure that the light source position of the light source outside the vehicle, the real-time light intensity of the light source, and the eye position of the driver inside the vehicle can be truly monitored, the light tracking module and the light sensor are both arranged on the outside of the top of the car, and the camera is arranged on the inside of the top of the car, so as to improve the accuracy of judging the real impact of light on the driver.

[0049] Furthermore, the sun visor includes a driving member, a base plate and a slide rail, the slide rail is arranged on the inner side of the top of the car, the base plate and the slide rail are relatively movably connected, and the driving member is used to drive the base plate to extend and retract along the length direction of the slide rail. The driving member mentioned here may refer to a servo motor. Compared with the solution of using an automatic rotating sun visor, the telescopic sun visor is not only beneficial to meet the driver's expectations for the ideal expected position, but also can avoid the safety hazard of the driver's head being touched by the sun visor when it moves, causing the driver to be unable to concentrate.

[0050] An embodiment of the third aspect of the present invention provides an automobile, comprising the automobile sun visor adjustment system as described in the above embodiment, so that the automobile has the characteristics of comfortable and safe driving experience.

[0051] In order to facilitate understanding of the design concept of the present invention, Figure 3 As shown, the technical principle is explained as follows:

[0052] The adjustment function is turned on or off through the soft switch on the central control screen of the car. When the adjustment function is turned on, the suppression state of automatic adjustment is checked first. If the suppression state of automatic adjustment is turned on, the light effect on the driver is not judged; if the suppression state of automatic adjustment is not turned on, the light effect on the driver is judged. When the light has no effect on the driver, the sun visor is not adjusted; when the light has an effect on the driver, the automatic adjustment of the sun visor is triggered. It is worth mentioning that during the automatic adjustment of the sun visor, it is also judged whether there is manual control action by the driver. If there is no manual control action, the sun visor is automatically adjusted to the target position; if there is manual control action, the automatic adjustment is first suppressed, and the manual control is responded to at the same time, and then a pop-up window is displayed on the screen to remind "manual control of the sun visor is detected, please confirm whether to turn off the automatic adjustment function". If the user selects "Yes", the automatic adjustment function is turned off and the automatic adjustment is suppressed, and the soft switch is grayed out until the next power-on cycle of the car, when the automatic adjustment of the sun visor state is re-enabled; if the user selects "No", the automatic adjustment function remains on and the automatic adjustment is suppressed until the next power-on cycle of the car, when the automatic adjustment of the sun visor state is re-enabled, and the logic ends. In this way, adaptive control of the sun visor is achieved without affecting the manual adjustment of the driver's subjective will.

[0053] Compared with the prior art, the present invention has the following beneficial effects:

[0054] The present invention first determines whether to adjust the sun visor, and then determines the target position of the sun visor when the sun visor needs to be adjusted, based on the real-time illumination intensity of the light source outside the vehicle, the first angle between the line connecting the light source position and the front windshield relative to the vertical direction, and the second angle between the line connecting the driver's eye position and the front windshield relative to the vertical direction. This not only meets the driver's adaptive adjustment requirements for the sun visor, but also helps improve the driver's driving safety. Compared with the prior art scheme of using the driver's pupil reaction to adjust the sun visor, and using GPS to determine the vehicle's driving direction to determine the impact of illumination on the driver, the present invention avoids the interference of differences in pupil size, changes in latitude and other working conditions on determining whether illumination has really affected the driver, and greatly reduces the frequency of false triggering of the sun visor action due to misjudgment of the impact of illumination on the driver, which is beneficial to improving the driver's driving experience and ensuring concentration during driving.

[0055] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
