It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, a vehicle window control method provided for the embodiment of the present invention may be executed by a vehicle window control device provided in the embodiment of the present invention, where the vehicle window control device may be implemented in a software and/or hardware manner, and the vehicle window control method includes the following steps:

step S101: obtaining the light intensity of surrounding vehicles;

in one embodiment, the obtaining of the surrounding vehicle light intensity comprises the following steps:

and monitoring the light intensity of the surrounding vehicles in real time at night.

Particularly, a photosensitive electronic component can be added on the vehicle, and the light intensity of surrounding vehicles can be monitored in real time through the photosensitive electronic component when the vehicle runs at night.

In one embodiment, after obtaining the light intensity of the surrounding vehicle, the method further includes the following steps:

and when the light intensity of the surrounding vehicles is greater than a first preset light intensity, controlling the inside and outside rearview mirrors to start an anti-dazzling function.

Here, the first preset light intensity may be set in advance according to an actual application scenario, and for example, may be set to 3500 lumens, 3600 lumens, 3700 lumens, and the like. It should be noted that the anti-glare rearview mirror is composed of a special mirror, two photodiodes and an electronic controller, wherein the electronic controller receives front and rear light signals sent by the photodiodes, is arranged below a front windshield of a carriage, and can be divided into an automatic anti-glare rearview mirror and a manual anti-glare rearview mirror.

The principle of the automatic anti-glare rearview mirror is as follows: when the interior anti-dazzle rearview mirror is irradiated by a headlight of a rear vehicle, the interior anti-dazzle rearview mirror has a constantly changing anti-dazzle function. The electronic controller obtains the signal of the front light or the back light from the photosensitive diode, if the irradiating light irradiates on the interior rearview mirror, for example, the back light is larger than the front light, the electronic controller will output a voltage to the conductive layer. The voltage on the conducting layer changes the color of the electro-hydraulic, the higher the voltage, the darker the color of the electro-hydraulic, at this time, even if the strong irradiating light irradiates the rearview mirror, the dark light is reflected to the eyes of the driver by the anti-dazzle rearview mirror in the automobile, but the dark light is not dazzled. The mirror surface electrochemical layer automatically and continuously changes according to the incident intensity of the rear light to prevent dazzling.

In addition, the manual anti-glare rearview mirror is provided with a black small shifting piece on the back surface (generally on the center lower end) of the rearview mirror, the black small shifting piece faces the front windshield in a normal state, and the mirror surface of the rearview mirror slightly changes in angle as long as the manual anti-glare rearview mirror is slightly shifted towards the interior of the vehicle, so that the interior of the vehicle is manually adjusted to have an anti-glare effect. The manual anti-glare rearview mirror is not a plane mirror with the same thickness, but a wedge-shaped mirror with an included angle of about 10 degrees, and the upper end of the manual anti-glare rearview mirror is made of a material with a thickness larger than that of the lower end of the manual anti-glare rearview mirror. The principle is as follows: in a common state, light rays are reflected to eyes of a driver after being refracted through a mirror coating on the back, and the principle of the common plane mirror is also adopted. After the anti-dazzling effect is achieved through manual adjustment, the whole mirror surface can be adjusted upwards by about 10 degrees (the included angle of the whole mirror surface is the same as the included angle of the cross section of the mirror), and the semi-transparent film coating light-transmitting layer of the rearview mirror is observed by a driver at the moment and has a low refractive index to light rays, so that the anti-dazzling effect is achieved.

Step S102: acquiring the target transparency of the vehicle window corresponding to the light intensity of the surrounding vehicle;

in one embodiment, the obtaining of the target transparency of the window corresponding to the surrounding vehicle light intensity includes the following steps:

when the light intensity of the surrounding vehicle is greater than or equal to a second preset light intensity, acquiring a first target transparency;

when the light intensity of the surrounding vehicle is greater than a third preset light intensity and less than a second preset light intensity, acquiring a second target transparency;

when the light intensity of the surrounding vehicle is smaller than or equal to a third preset light intensity, acquiring a third target transparency;

the second preset light intensity is larger than the third preset light intensity, the first target transparency is smaller than the second target transparency, and the second target transparency is smaller than the third target transparency.

Here, by setting the second preset light intensity and the third preset light intensity, and the second preset light intensity is greater than the third preset light intensity, the light intensity is divided into three ranges, that is, the second preset light intensity is greater than or equal to, the third preset light intensity is greater than, and the second preset light intensity is less than, and the third preset light intensity is less than. The second preset light intensity and the third preset light intensity may be set in advance according to actual application scenarios, for example, the second preset light intensity may be set to 4000 lumens, and the third preset light intensity may be set to 3000 lumens, etc. And according to the obtained light intensity of the surrounding vehicles, comparing and analyzing the light intensity with second preset light intensity and third preset light intensity, and obtaining the target transparency of the corresponding vehicle window. It should be noted that the first target transparency is smaller than the second target transparency, the second target transparency is smaller than the third target transparency, and the first target transparency, the second target transparency, and the third target transparency may be set in advance according to actual application scenarios, for example, the light transmittance of the first target transparency may be set to be greater than or equal to 20% and less than or equal to 40%, the light transmittance of the second target transparency is greater than or equal to 60% and less than or equal to 80%, the light transmittance of the third target transparency is greater than or equal to 90%, and the like. It is understood that the greater the light transmittance of the window, the higher the transparency, whereas the smaller the light transmittance, the lower the transparency. Therefore, according to the corresponding relation between the light intensity of the surrounding vehicle and the preset light intensity range, the target transparency of the vehicle window corresponding to the light intensity of the surrounding vehicle can be obtained, the complexity of obtaining the target transparency of the vehicle window is simplified, and the accuracy of obtaining the target transparency of the vehicle window is improved.

and when the light intensity of the rear vehicle is greater than the preset light intensity of the rear vehicle, acquiring the target transparency of the rear vehicle window, wherein the target transparency corresponds to the light intensity of the rear vehicle.

It should be noted that, in the present embodiment, the number and the setting position of the windows are not limited, and the number and the setting position of the windows may be different depending on the type of the vehicle. In practical application, the window corresponding to the irradiation direction can be obtained according to the irradiation direction of the surrounding vehicle light, and then the target transparency of the window corresponding to the intensity of the surrounding vehicle light is obtained. When the vehicle comes from the rear, the light intensity of the rear vehicle is obtained, if the light intensity of the rear vehicle is larger than the preset light intensity of the rear, the target transparency of the rear vehicle window is obtained, and the target transparency corresponds to the light intensity of the rear vehicle. The rear preset light intensity can be set in advance according to actual application scenes, for example, the rear preset light intensity can be set to 3000 lumens, 3500 lumens, 4000 lumens and the like. Therefore, the target transparency of the corresponding car window is obtained according to the irradiation direction of the surrounding car light, the accuracy and the reasonability of obtaining the target transparency of the car window are further improved, and the use experience of a user is improved.

Step S103: and controlling the car window to adjust the transparency according to the target transparency.

Specifically, after the target transparency of the vehicle window corresponding to the light intensity of the surrounding vehicle is obtained in step S102, an adjustment instruction may be sent to the vehicle window according to the target transparency to control the vehicle window to adjust the transparency, so that the transparency of the vehicle window is adjusted according to the light intensity of the surrounding vehicle, the driving safety of a user may be improved, and the user experience is improved.

It should be noted that, in the present embodiment, the value of adjusting the transparency of the vehicle window according to the target transparency is not limited, and may be different according to different factors such as the material of the vehicle window, the structure of the vehicle window, and the like. For example, the glass of the vehicle window can adopt light control glass, which is also called intelligent electric control light control glass, electric control glass, intelligent light control glass, magic glass, liquid crystal glass and the like. The light-adjusting glass is a novel special photoelectric glass product with a sandwich structure, wherein a liquid crystal film is compounded between two layers of glass and is integrally formed after high-temperature pressing and gluing, and the transparent and non-transparent states of the glass are controlled by controlling the on-off state of current. The working principle of the light-adjusting glass is as follows; when the power supply of the light control glass is turned off, liquid crystal molecules in the electric control light control glass are in an irregular dispersion state, and the electric control glass is in a transparent and opaque appearance state; when the dimming glass is electrified, the liquid crystal molecules in the dimming glass are arranged in order, light can penetrate through the dimming glass freely, and the dimming glass is in a transparent state instantly. Because the liquid crystal film has the characteristics of being in a fog state in a power-off state and being in a transparent state when being electrified, the dimming glass has the characteristics of common glass and the electric control curtain, and the transparency of the car window can be effectively adjusted.

In summary, in the window control method provided in the above embodiment, the light intensity of the surrounding vehicle is obtained, then the target transparency of the window corresponding to the light intensity of the surrounding vehicle is obtained, and then the window is controlled to adjust the transparency according to the target transparency. The target transparency of the car window corresponding to the light intensity of surrounding vehicles is obtained, and then the transparency is adjusted by controlling the car window according to the target transparency, so that the driving safety of a user can be improved, and the use experience of the user is improved.

In an embodiment, before controlling the vehicle window to adjust transparency according to the target transparency, the method further includes the following steps:

controlling a camera to acquire image information of surrounding vehicles;

and controlling a display device to display the surrounding vehicle image information.

Specifically, the control camera acquires the image information of the surrounding vehicle, which may be acquired by controlling a camera mounted on the vehicle to shoot the surrounding vehicle in a preset area (such as a picture, a video, etc.). The camera of installation can be 360 degrees panorama cameras on the vehicle, also can be for setting up the camera group of arranging the rule and installing on the vehicle according to setting for, and the camera group can shoot the scene around the vehicle to the realization is to the shooting of vehicle around. The control display device displays the surrounding vehicle image information, and the collected surrounding vehicle image information can be sent to a central display screen and other display devices for display so as to be viewed by a user. In the embodiment of the invention, the image information of the surrounding vehicles is acquired through the camera before the transparency of the vehicle window is controlled to be adjusted, and the image information of the surrounding vehicles is controlled to be displayed by the display device, so that the driving condition of the surrounding vehicles can not be accurately judged by a user due to the reduction of the transparency of the vehicle window, the user can conveniently perform lane changing, vehicle avoiding, braking and other operations at the first time according to the driving condition of the surrounding vehicles, and the driving safety of the user is further improved.

In one embodiment, the controlling the vehicle window to adjust the transparency according to the target transparency comprises the following steps:

and when the current transparency of the rear window is greater than the target transparency, automatically reducing the transparency of the rear window.

It should be noted that, in the present embodiment, the window whose transparency needs to be adjusted is not limited, and may be different according to the corresponding relationship between the irradiation direction of the surrounding vehicle light and the window. Here, after the target transparency of the rear window corresponding to the rear vehicle light intensity is acquired, an adjustment instruction may be sent to the rear window according to the target transparency to control the rear window to adjust the transparency. When the current transparency of the rear window is greater than the target transparency, automatically reducing the transparency of the rear window, which may be directly automatically reducing the current transparency of the rear window to the target transparency after the target transparency is obtained, or comprehensively analyzing by combining other factors such as the current vehicle speed and the external light intensity to obtain the current adjustable low transparency, and then automatically reducing the transparency of the rear window to the current adjustable low transparency. For example, the current transparency of the rear window is 90%, the target transparency is 60%, and the transparency of the rear window can be automatically reduced to 60%, or, since the current vehicle speed is fast and the external light intensity is low, the current adjustable low transparency obtained by comprehensive analysis is 70%, and the transparency of the rear window can also be automatically reduced to 70%. Therefore, the transparency of the car window is automatically reduced according to the target transparency, the driving safety of a user is improved, and the use experience of the user is improved.
