Specifically, fig. 1 is a schematic flow chart of a method for adjusting transmittance of a vehicle window glass according to an embodiment of the present application.
As shown in fig. 1, the method for adjusting the transmittance of the vehicle window glass comprises the following steps:
in step S101, first illumination intensities of four corners of a front windshield are acquired.
Specifically, in order to avoid the user to influence the sight because of light is too strong or weak in driving to increase driving potential safety hazard, this application embodiment needs based on illumination intensity's monitoring, automatically regulated front windshield's transmittance to the illumination intensity in the user acceptable range, thereby make the user can not receive the sight interference in driving, reduce the emergence of traffic accident.
Therefore, in the embodiment of the application, first, CMOS sensors are installed at four corners of a front windshield of a vehicle, first illumination intensities of the four corners of the front windshield are respectively collected through the CMOS sensors, and then the collected first illumination intensities are sent to a vehicle system for corresponding calculation.
Specifically, before a car runs, a user starts an automatic front windshield light transmittance adjusting function in a mobile phone APP, and sets an illumination intensity range acceptable to the user, wherein the illumination intensity range can be manually set by the user, and as the maximum visible light bright point value acceptable to eyes is about 106cd/m2, the illumination intensity range can be divided into 10 gears, the maximum gear is 106cd/m2, the user can manually input according to the situation of the user, and meanwhile, the user can also automatically set according to the maximum visible light bright point value acceptable to eyes, and the method is not particularly limited.
Secondly, after a user starts an automatic front windshield light transmittance adjusting function in a mobile phone APP, the CMOS sensor sends the first illumination intensity of the four corners of the collected front windshield to a vehicle-mounted system through a CAN bus, a native layer of the vehicle-mounted system calculates, and a result obtained after calculation is transmitted to an upper layer application.
In step S102, an average value of the first illumination intensities of the four corners is calculated, and it is determined whether the average value is in a preset intensity interval.
The preset intensity interval may be an illumination intensity interval set by a user according to the self situation, or may be an illumination intensity interval automatically set according to a maximum visible light brightness value acceptable to eyes, which is not limited herein specifically.
Specifically, in the embodiment of the application, after the vehicle-mounted system receives the first illumination intensities of the four corners of the front windshield, the native layer calculates an average value of the first illumination intensities of the four corners of the front windshield according to one time per second, and then compares the calculated average value of the first illumination intensity with an illumination intensity range (i.e., a preset intensity interval) set by a user, and determines whether the average value is in the preset intensity interval.
In step S103, if the average value is not in the preset intensity interval, calculating the target transmittance of the front windshield according to the maximum value of the preset intensity interval, the minimum value of the preset intensity interval, and the average value, and adjusting the current transmittance of the front windshield to the target transmittance.
According to one embodiment of the present application, if the average value is not in the preset intensity interval, the method includes: generating an illumination alarm instruction based on the average value of the first illumination intensity; and controlling the preset mobile terminal to alarm the user according to the illumination alarm instruction.
The preset mobile terminal may be a mobile terminal selected by a user according to a use requirement, for example, a mobile phone, a vehicle-mounted computer, and the like, which is not limited herein.
Specifically, in this embodiment of the present application, if the average value of the first illumination intensities of the four corners of the front windshield is not in the preset intensity interval, it is indicated that the first illumination intensity is too strong or too weak at this time, and the driving sight of the user is affected, so that an illumination alarm instruction needs to be generated based on the average value of the first illumination intensity, and the active layer controls the preset mobile terminal to alarm the user according to the illumination alarm instruction, for example, controls the mobile phone to vibrate, ring or controls the mobile phone display screen to flash to alarm the user based on the illumination alarm instruction.
According to one embodiment of the present application, calculating the target transmittance of the front windshield according to the maximum value of the preset intensity interval, the minimum value of the preset intensity interval, and the average value includes: when the average value is larger than the maximum value of the preset intensity interval, calculating the first target transmittance of the front windshield according to the difference value between the maximum value of the preset intensity interval and the average value; and when the average value is smaller than the minimum value of the preset intensity interval, calculating the second target transmittance of the front windshield according to the difference value between the minimum value of the preset intensity interval and the average value.
The first target transmittance and the second target transmittance are both illumination intensities within a user acceptable range.
Specifically, in the embodiment of the application, after receiving the alarm instruction of the first illumination intensity being too strong or too weak, the transmittance of the front windshield needs to be adjusted based on the alarm instruction, so that the front windshield is suitable for the driving vision of a user.
Specifically, as shown in fig. 2, if the average value of the first illumination intensities at the four corners of the front windshield is greater than the maximum value of the preset intensity interval, it is indicated that the first illumination intensity is too strong and exceeds the acceptable illumination intensity range of the user, that is, exceeds the maximum illumination intensity set by the user or exceeds the automatically generated maximum illumination intensity, and at this time, the first illumination intensity at the four corners of the front windshield needs to be reduced to meet the driving requirement of the user, so the first target transmittance of the front windshield needs to be calculated according to the difference value between the maximum value and the average value of the preset intensity interval.
Further, when the average value is smaller than the minimum value of the preset intensity interval, it is indicated that the first illumination intensity is too weak at this time and does not reach the illumination intensity range acceptable to the user, so that the user has an unclear line of sight in the driving process, and at this time, the first illumination intensities of the four corners of the front windshield need to be increased to meet the driving requirement of the user, so that the second target transmittance of the front windshield needs to be calculated according to the difference value between the minimum value and the average value of the preset intensity interval.
According to one embodiment of the present application, adjusting the current transmittance of the front windshield to a target transmittance includes: matching a first voltage signal corresponding to the target transmittance of the front windshield based on the target transmittance-voltage signal mapping table; and adjusting the current transmittance of the front windshield to the target transmittance according to the first voltage signal.
Specifically, as shown in fig. 2, after the target transmittance of the front windshield obtained by calculating the maximum value of the preset intensity interval, the minimum value of the preset intensity interval and the average value, the embodiment of the application matches the first voltage signal corresponding to the target transmittance of the front windshield based on the target transmittance-voltage signal mapping table, and adjusts the current transmittance of the front windshield to the transmittance of the illumination intensity range required by the user, that is, the target transmittance based on the first voltage signal.
According to an embodiment of the present application, the method for adjusting transmittance of a vehicle window glass further includes: judging whether the vehicle is in an unlocking state or not; and when the vehicle is in an unlocking state, acquiring user information in the vehicle, and acquiring second illumination intensity of glass at a preset position of the vehicle when the user information is acquired.
According to one embodiment of the present application, after obtaining the second illumination intensity of the glass at the preset position of the vehicle, the method further includes: matching a second voltage signal corresponding to the target transmittance of the glass at the preset position of the vehicle based on the target transmittance-voltage signal mapping table; and adjusting the current transmittance of the glass at the preset position of the vehicle to the target transmittance according to the second voltage signal.
The glass at the preset position can be a front windshield, a side glass and a rear windshield of the vehicle.
Specifically, in order to ensure the comfort of a user in parking and resting, the privacy of the user can be protected when the user parks and rests, so that the privacy space of the user is met.
Specifically, the embodiment of the application firstly judges whether the vehicle is in an unlocking state, and if the vehicle is in the unlocking state, the user client is in a parking state; secondly, user information in the vehicle is acquired when the vehicle is in an unlocking state, if the user information is acquired, the user is in the vehicle when parking, and the vehicle belongs to a private space of the user at the moment, so that the privacy of the user during resting is protected, the second illumination intensities of the front windshield, the side glass and the rear windshield of the vehicle at the moment can be acquired, second voltage signals corresponding to target transmittances of the front windshield, the side glass and the rear windshield of the vehicle are matched based on a target transmittance-voltage signal mapping table, and the current transmittances of the front windshield, the side glass and the rear windshield of the vehicle are adjusted to the target transmittances required by the user according to the second voltage signals, so that the privacy of the user is protected, and the resting experience of the user is improved.
Further, as shown in fig. 3, the protection principle of the embodiment of the present application is that when the target transmittance of the front windshield, the side glass and the rear windshield of the vehicle is adjusted to protect privacy of a user during a stop and rest, a layer of liquid crystal dimming film layer is sandwiched between two pieces of dimming glass, and when the two pieces of dimming glass are electrified, a high-quality liquid crystal dimming glass film is formed, that is, liquid crystal cells with the size of several micrometers are dispersed on the glass collectively, and sandwiched between transparent conductive films, so that a special sandwich structure is formed, and when light irradiates the front windshield, the side glass and the rear windshield of the vehicle, the light is subjected to a strong scattering effect, so that the transparency of the glass disappears; when a voltage signal is applied between the two transparent conductive films, the liquid crystal molecules are aligned to the glass surface, and light can directly pass through the transparent conductive films to show transparency, so that privacy protection of users is realized based on the characteristics.
For example, if a user is in a meeting condition during driving at night, a high beam is turned on for the opposite vehicle, and the illumination intensity of the high beam exceeds the illumination intensity acceptable by the user, namely exceeds the maximum value of a preset intensity interval, and the driving sight of the user is blocked at the moment, so when the illumination intensity of the high beam is monitored to exceed the illumination intensity acceptable by the user, the active layer controls the mobile phone APP page to give an alarm to the user, and the user is reminded that the illumination intensity of the front windshield is about to be adjusted when the current illumination intensity is too strong; secondly, the active layer calculates the required target transmittance of the front windshield by using a fixed algorithm according to the difference value of the preset intensity interval set by a user and the average value of the first illumination intensity, and matches the first voltage signal corresponding to the target transmittance of the front windshield based on the target transmittance-voltage signal mapping table, and adjusts the current transmittance of the front windshield to the transmittance of the illumination intensity range required by the user based on the first voltage signal.
It should be noted that the above embodiments are only exemplary, and the embodiments of the present application may be applied to related scenes with too strong or too weak illumination intensity, such as meeting at night and driving in daytime, so as to enable a user to normally drive when the illumination intensity is too strong or too weak, without using auxiliary devices, such as sunshading boards, so as to improve the driving experience of the user.
According to the method for adjusting the transmittance of the vehicle window glass, the first illumination intensities of the four corners of the front windshield are obtained, the average value of the first illumination intensities is calculated, when the average value is not in the preset intensity interval, the target transmittance of the front windshield is calculated according to the maximum value of the preset intensity interval, the minimum value of the preset intensity interval and the average value, and the current transmittance of the front windshield is adjusted to the target transmittance. Therefore, the problems that the sight of a user can be influenced when the light is too strong or too weak in the driving process, the driving potential safety hazard is increased and the like are solved, the target transmittance of the front windshield is obtained based on the average value of the illumination intensity of the front windshield and the maximum value and the minimum value of the preset intensity interval, so that the current transmittance of the front windshield can be automatically adjusted to the target transmittance when the light is too strong or too weak, the driving safety is improved, and the driving experience of the user is improved.
