The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0032] The control method and device of vehicle glass of the embodiments of the present application are described below with reference to the accompanying drawings. In view of the problem that there is no specific light adjustment standard in the related art mentioned in the background, only an average color change value can be adjusted according to scene simulation, and the overall color change of the glass easily affects the driver's vision, resulting in errors in the specific position judgment of external objects, thereby affecting driving safety and reducing driving experience, the present application provides a control method of vehicle glass, in which the target adjustment area of the vehicle glass can be determined according to the light source position of at least one light source and the actual field of view of the driver, and the vehicle glass is color adjusted in the local area according to the light source intensity, so as to realize intelligent light sensing adjustment of the glass, achieve the effect of filtering strong light, ensure that the driver can see the road condition information in a strong light scene, ensure driving safety, and improve the visual experience and driving experience of the driver. Thus, the problems such as no specific light adjustment standard in the related art, only an average color change value can be adjusted according to scene simulation, and the overall color change of the glass easily affects the driver's vision, resulting in errors in the specific position judgment of external objects, thereby affecting driving safety and reducing driving experience are solved.

[0033] Specifically, Figure 1 A flowchart of a control method of vehicle glass provided by an embodiment of the present application is shown.

[0034] As Figure 1 shown, the control method of vehicle glass includes the following steps:

[0035] In step S101, the light source position and light source intensity of at least one light source outside the vehicle are obtained.

[0036] It can be understood that the embodiments of the present application can collect external real-time pictures through the installation of a DVR (Digital Video Recorder) camera and a matching intelligent system, and obtain key frames from the pictures collected by the DVR camera for detection of the external light environment.

[0037] In actual implementation, the embodiment of the application can acquire the key frame through the DVR camera head to detect the external light environment, and collect the light information through the vehicle sensor to acquire the light source position and the light source intensity of at least one light source outside the vehicle, thereby providing support for subsequent implementation of intelligent photosensitive adjustment of the glass, local adjustment of the glass discoloration, achieving the effect of filtering strong light, ensuring that the driver can see the road condition information in the strong light scene, ensuring driving safety, and improving the visual experience and driving experience of the driver.

[0038] In step S102, it is judged whether the light source intensity of the at least one light source meets the preset protection condition.

[0039] It can be understood that the light source in the embodiment of the application can be but is not limited to the vehicle high beam and the strong sunlight; and the preset protection condition can be that the light source intensity of the vehicle high beam or the strong sunlight exceeds the brightness recognizable by the human eye.

[0040] As a possible implementation manner, the embodiment of the application can judge whether the light source intensity of the at least one light source meets a certain protection condition, thereby ensuring that the high beam and the strong light are prevented under the protection condition, and improving the visual experience of the driver. For example, when the at least one light source is the vehicle high beam and the light source intensity of the vehicle high beam exceeds the brightness recognizable by the human eye, it is determined that the at least one light source meets a certain protection condition; for another example, when the at least one light source is the strong sunlight and the light source brightness of the strong sunlight exceeds the brightness recognizable by the human eye, it is determined that the at least one light source meets a certain protection condition; for another example, when the light source brightness of the at least one light source is the high beam and the strong light of the vehicle high beam simultaneously exceeds the brightness recognizable by the human eye, it is determined that the at least one light source meets a certain protection condition.

[0041] It should be noted that the preset protection condition can be set by the person skilled in the art according to the actual situation, which is not specifically limited herein.

[0042] Optionally, in an embodiment of the application, before judging whether the at least one light source meets the preset protection condition, it further includes: identifying the current scene in which the vehicle is located; and determining the preset protection condition according to the current scene.

[0043] It can be understood that the embodiment of the application can identify the current scene in which the vehicle is located through the rain sensor and the external real-time picture, and analyze the environmental information of the current scene, such as judging whether it is rainy, overcast, night or day, for example, when the rain sensor detects that the rain falls on the front windshield, it is determined that the current scene is a rainy scene; for another example, when the stars appear in the external implementation picture, it is determined that the current scene is a night scene.

[0044] In actual implementation, the embodiment of the present application can identify the current scene of the vehicle, ensure that the light source intensity is analyzed according to different scenes, and effectively prevent high beams and strong light; the embodiment of the present application can determine certain protection conditions according to the current scene, for example, the embodiment of the present application can acquire the light source intensity of the high beam of the vehicle in the current scene when the current scene of the vehicle is rainy and at night, and determine certain protection conditions; for another example, the embodiment of the present application can acquire the light source intensity of the high beam of the vehicle and the strong light of the sun in the current scene when the current scene of the vehicle is cloudy and at day, and determine certain protection conditions, thereby ensuring that the high beams and strong light are further prevented under the protection conditions, and improving the visual experience of the driver.

[0045] Optionally, in an embodiment of the present application, the preset protection condition is determined according to the current scene, comprising: in the case that the current scene is a day scene, the preset protection condition is that the light source intensity is greater than a first preset threshold; in the case that the current scene is a night scene, the preset protection condition is that the light source intensity is greater than a second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0046] Specifically, the embodiment of the present application can analyze whether there is a high beam or strong light source through the DVR in the case that the current scene is a day scene, the preset protection condition is that the light source intensity is greater than a first preset threshold, for example, the first preset threshold can be 600 lux of the light source intensity of the strong light of the sun when the embodiment of the present application is in a day scene, and the actual light source intensity of the strong light of the sun can be 1500 lux, at this time, the light source intensity is greater than the first preset threshold, and the preset protection condition is met.

[0047] The embodiment of the present application can analyze whether there is a high beam or strong light source through the DVR in the case that the current scene is a night scene, the preset protection condition is that the light source intensity is greater than a second preset threshold, wherein the second preset threshold is less than the first preset threshold, for example, the second preset threshold can be 400 lux of the light source intensity of the high beam of the vehicle coming from the opposite direction when the embodiment of the present application is in a night scene, and the actual light source intensity of the high beam of the vehicle can be 900 lux, at this time, the light source intensity is greater than the second preset threshold, and the second threshold is less than the first preset threshold.

[0048] The embodiment of the present application can compare different light source intensities according to the day scene and the night scene, and adjust the prevention of high beams and strong light in a targeted manner, which not only solves the influence of the high beam on driving safety at night, but also solves the influence of the strong light of the sun on driving safety in the day, achieves the effect of filtering strong light, and ensures that the driver can see the road condition information in the strong light scene.

[0049] It should be noted that the preset protection condition, the first preset threshold and the second preset threshold can be set by those skilled in the art according to actual conditions, and are not specifically limited here.

[0050] Optionally, in an embodiment of the present application, the preset protection condition is determined according to the current scene, and further includes: in the case that the current scene is a tunnel scene, the preset protection condition is that the light source intensity is greater than a third preset threshold, wherein the third preset threshold is less than the first preset threshold and greater than the second preset threshold.

[0051] For example, the embodiment of the present application can determine whether there is a tunnel section on the driving section in front of the vehicle according to navigation detection. In the case that the current scene is a tunnel scene and in the night high beam mode, since the night is a process from darkness to brightness, it does not affect the driver to achieve, so it does not need to be processed. In the case that the current scene is a tunnel scene and in the daytime scene, the preset protection condition is that the light source intensity is greater than a third preset threshold, wherein the third preset threshold is less than the first preset threshold and greater than the second preset threshold. For example, the light source intensity of the high beam of the vehicle driving from the opposite direction can be 500 lux, the light source intensity of the actual high beam of the vehicle can be 900 lux, and the light source intensity of the actual strong sunlight can be 1500 lux. At this time, the third preset threshold is less than the first preset threshold and greater than the second preset threshold. The embodiment of the present application can calculate the distance from the current vehicle to the tunnel. When the distance is less than 100 m, the discolored mode is prepared in advance, the glass discoloration is turned off, and the vehicle is prevented from entering the tunnel. When the vehicle leaves the tunnel, the local glass discoloration setting before entering the tunnel can be restored or adjusted in real time according to the current condition.

[0052] The embodiment of the present application can specifically analyze the local discoloration adjustment of the vehicle glass in the daytime scene and the night scene in the case that the current scene is a tunnel scene, so as to improve the visual perception and driving experience of the driver.

[0053] It should be noted that the preset protection condition, the first preset threshold, the second preset threshold and the third preset threshold can be set by those skilled in the art according to actual conditions, and are not specifically limited here.

[0054] In step S103, in the case that the at least one light source meets the preset protection condition, a target adjustment region of the vehicle glass is identified according to the light source position of the at least one light source and the actual field of view of the driver, and a target adjustment action of the target adjustment region is matched according to the light source intensity of the at least one light source, so as to perform the target adjustment action in the target adjustment region.

[0055] It can be understood that the vehicle glass in the embodiments of the present application is mainly the front windshield of the vehicle, and the left and right rearview mirrors of the vehicle can also be applicable, wherein the automobile needs to purchase electrochromic glass, and the front windshield needs to be regionally divided to facilitate subsequent regional local adjustment.

[0056] In actual execution, the embodiments of the present application can identify the target adjustment area of the vehicle glass according to the light source position of the at least one light source and the actual visual field of the driver in the case that the at least one light source meets certain protection conditions, and match the target adjustment action of the target adjustment area according to the light source intensity of the at least one light source, to perform the target adjustment action in the target adjustment area, so as to ensure that the target adjustment area of the vehicle glass can be determined according to the light source position and the actual visual field of the driver, and the vehicle glass can be locally adjusted in color according to the light source intensity, to realize intelligent and regional local light processing, intelligent light sensing adjustment of the glass, achieve the effect of locally adjusting the front windshield filter light according to the driver's visual angle, ensure that the driver can see the road condition information in a strong light scene, ensure driving safety, and improve the visual experience and driving experience of the driver.

[0057] It should be noted that the preset protection condition can be set by those skilled in the art according to actual conditions, which is not limited here.

[0058] Optionally, in an embodiment of the present application, identifying the target adjustment area of the vehicle glass according to the light source position of the at least one light source and the actual visual field of the driver comprises: obtaining eye visual angle direction information of the driver in the actual visual field of the driver; judging whether the eye visual angle direction information of the driver meets the incidence angle of the at least one light source, if the eye visual angle direction information of the driver meets the incidence angle of the at least one light source, then determining the target adjustment area of the vehicle glass according to the light source position of the at least one light source and the actual visual field of the driver.

[0059] It can be understood that the vehicle glass in the embodiments of the present application is mainly the front windshield of the vehicle, and the left and right rearview mirrors of the vehicle can also be applicable; the embodiments of the present application can calculate the relationship between the visual angle of the driver and the light by the visual perception device such as DMS (Driver Monitor System, driver monitoring system) to judge whether the light outside the vehicle affects the visual line of the driver.

[0060] For example, the embodiment of the present application can acquire the eye perspective position information of the driver in the actual field of view of the driver through the DMS, determine whether the perspective position information of the driver meets the incident angle of the at least one light source, and when the incident angle of the light source in the perspective of the driver, i.e., the incident angle of the light source in the perspective of the driver, is within a 10° angle position, it is indicated that the light in the corresponding range interferes with the driver. At this time, the target adjustment area of the front windshield of the vehicle can be determined according to the light source position of the at least one light source and the actual field of view of the driver.

[0061] The embodiment of the present application can provide support for controlling the local color adjustment of the vehicle glass according to the target adjustment area of the vehicle, effectively reduce the direct stimulation of high beams and strong light on the eyes of the driver, and improve the driving safety of the driver.

[0062] It should be noted that the embodiment of the present application can intelligently adjust the local light filtering of the glass, and make reasonable glass light filtering control on the external environment in combination with navigation, cameras, vehicle sensors and the like.

[0063] Optionally, in an embodiment of the present application, the target adjustment action of matching the target adjustment area according to the light source intensity of the at least one light source includes: performing power color adjustment on the vehicle glass according to the light source intensity of the at least one light source, wherein the local adjustment color change value of the target adjustment area of the vehicle glass is controlled based on different levels of voltage.

[0064] As a possible implementation manner, the embodiment of the present application can perform power color adjustment on the vehicle glass through the glass controller according to the light source intensity of the at least one light source in combination with the driver perspective position information. It should be noted that the target adjustment area of the vehicle glass can send different levels of voltage to control the degree of glass color change, so as to ensure that based on the light source intensity and position, in combination with the driver perspective position, the light source position, the external light intensity, the weather and the like, the regional glass color adjustment is performed based on the electrochromic glass, part of the external light source is absorbed, and the brightness recognizable by the human eye is achieved.

[0065] For example, in the night scene, when the high beam signal of the vehicle high beam is not detected for a certain period of time, the color changing control is released to restore the original state of the glass, when the high beam signal of the vehicle high beam is repeatedly received for a certain period of time, the user is prompted whether to always turn on the night high beam mode, in the night high beam mode, a reasonable color changing value can be set for the entire front windshield of the vehicle according to the overall light intensity of the current night outside, when the high beam exceeds the current color changing value, the color changing value can be locally adjusted, and then locally restored to the color changing value of the previous night high beam mode, so as to finally control the local adjustment color changing value of the target adjustment area of the vehicle glass. For another example, in the daytime scene, a reasonable color changing value can be set for the entire front windshield according to the overall light intensity of the outside of the vehicle.

[0066] Specifically, in combination with Figures 2 to 6 , the working principle of the control method of the vehicle glass in the embodiments of the application is described in detail.

[0067] As Figure 2 shown, the embodiments of the application can combine vehicle sensors, DMS, DVR and navigation, etc. to perform image processing, logic control and glass control, so as to ensure reasonable glass filtering control of the external environment, ensure driving safety, and improve the visual experience and driving experience of the driver.

[0068] As Figure 3 shown, in the night scene, the embodiments of the application can include the following steps:

[0069] Step S301: Real-time DVR, DMS, navigation data acquisition.

[0070] In the embodiments of the application, the DVR camera and the DMS camera can be added to perform real-time data acquisition in combination with the navigation.

[0071] Step S302: Whether there is a high beam recognition, if yes, step S303 is performed, if no, step S301 is performed.

[0072] Step S303: Whether the high beam signal is repeatedly received, if yes, step S304 is performed, if no, step S306 is performed.

[0073] Step S304: Pop-up box confirmation whether to start the night high beam mode.

[0074] In the embodiments of the application, the pop-up box confirmation whether to start the night high beam mode can improve the driving experience of the driver and ensure the intelligence and practicality of the vehicle.

[0075] Step S305: Start.

[0076] In this embodiment, the nighttime high beam mode can be enabled.

[0077] Step S306: Calculate whether the driver's field of view information matches the incident angle of the high beam.

[0078] In this embodiment, the driver's perspective information and the incident angle of the high beam can be calculated to determine whether they are within a certain angular orientation.

[0079] Step S307: Is the angle less than 10°? If yes, proceed to step S308; otherwise, proceed to step S309.

[0080] In this embodiment, the driver's viewing angle information and whether the incident angle of the high beam is less than 10° can be calculated. If yes, step S308 is executed; if no, step S309 is executed.

[0081] Step S308: Calculate the light source intensity and call the glass control unit.

[0082] In this embodiment, the glass control unit can be a glass control function. When the driver's field of vision is less than 10°, it can control the local color adjustment of the vehicle glass according to the target adjustment area of ​​the vehicle, effectively reducing the direct stimulation of the driver's eyes by high beams and strong light, and improving the driver's driving safety.

[0083] Step S309: Do not process.

[0084] Step S310: Apply electricity to adjust the color of the glass.

[0085] In this embodiment, the degree of color change can be controlled by sending different levels of voltage to the corresponding area through the glass controller based on light intensity information and driver's viewing position information.

[0086] Step S311: Start the high beam timer.

[0087] In this embodiment, a high beam timer can be activated, which helps to determine whether high beams are detected within a certain period of time, and thus decide whether to control local discoloration of the glass.

[0088] Furthermore, such as Figure 4 As shown, nighttime scene restoration, in this embodiment of the application, may include the following steps:

[0089] Step S401: The high beam timer ends, and no high beam signal is received.

[0090] Step S402: Determine whether the night high beam mode is in. If yes, proceed to step S403; otherwise, proceed to step S404.

[0091] Step S403: Do not process.

[0092] In this embodiment, no processing is required when the device is in nighttime high beam mode.

[0093] Step S404: Turn off glass color change and restore the default state.

[0094] In this embodiment of the application, when the high beam timer ends and no high beam signal is received, the color-changing control can be deactivated, the glass color-changing function can be turned off, and the default state can be restored.

[0095] like Figure 5 As shown, with the daytime scene activated, this application embodiment may include the following steps:

[0096] Step S501: Real-time DVR, DMS, and navigation data acquisition.

[0097] In this embodiment, a DVR camera and a DMS camera can be added to collect data in real time in conjunction with navigation.

[0098] Step S502: Is the sunlight too bright? If yes, proceed to step S503; otherwise, proceed to step S501.

[0099] In this embodiment, it can determine whether the sunlight is glaring. If so, step S503 is executed; if not, step S501 is executed.

[0100] Step S503: Calculate the light intensity and color change value, and call the glass control unit.

[0101] In this embodiment, the glass control unit can be a glass control function. When the driver's field of vision is less than 10°, it can control the local color adjustment of the vehicle glass according to the target adjustment area of ​​the vehicle, effectively reducing the direct stimulation of the driver's eyes by high beams and strong light, and improving the driver's driving safety.

[0102] Step S504: Apply electricity to adjust the color of the glass.

[0103] In this embodiment, the degree of color change can be controlled by sending different levels of voltage to the corresponding area through the glass controller based on light intensity information and driver's viewing position information.

[0104] Next, as Figure 6 As shown, in a daytime tunnel scenario, the embodiments of this application may include the following steps:

[0105] Step S601: The navigation system detected a tunnel ahead.
