Active anti-dazzle method and vehicle active anti-dazzle device

Abstract

The invention relates to an active anti-dazzle method and a vehicle active anti-dazzle device. The methodcomprises the steps that dimming glass with a plurality of independent liquid crystal membrane partitions serves as a vehicle front windshield, the light intensity of each kind of light source in front of a vehicle is detected in real time, the light sources which can make a driver of the vehicle be dazzled are found out, by positioning the light sources which can make the driver of the vehicle be dazzled, the eyes of the driver and the dimming glass, the partition where the point of intersection of light rays, irradiating the eyes of the driver, of the light sources which can make the driver of the vehicle be dazzled on the dimming glass belongs is found out, and the light transmissivity of the corresponding partition is adjusted by adjusting current. The device comprises the front windshield, a controller, a light intensity detecting device, a light source position detecting device and a human eye positioning device; the front windshield is the electric-control dimming glass, and a liquid crystal membrane inside the dimming glass is set to be the multiple independent partitions; and the partitions, the detecting devices and the human eye positioning device are in data connection with the controller. The active anti-dazzle method and the vehicle active anti-dazzle device can achieve the active anti-dazzle function, improve the driving safety and effectively delay aging of interior trim of the vehicle.

Description

technical field [0001] The invention relates to an active anti-dazzle method and an active anti-dazzle device for automobiles, belonging to the technical field of automobile lighting. Background technique [0002] With the rapid development of automobile technology, automobile driving safety has been paid more and more attention. Especially when driving at night, the lights of cars driving on the opposite side, the light of the flash of the road camera and the strong light in various emergencies will stimulate the driver's eyes and cause dazzling. At present, commonly used anti-glare methods include anti-glare headlights, anti-glare glasses, and anti-glare LCD screens. Among them, the anti-dazzling headlights can reduce the risk of dazzling the driver of the opposite vehicle to a certain extent, but if the oncoming car is not equipped with anti-dazzle headlights, it is very likely to dazzle the driver of the vehicle, which is dangerous. The driver of the vehicle is driving...

Among them, the anti-dazzling headlights can reduce the risk of dazzling the driver of the opposite vehicle to a certain extent, but if the oncoming car is not equipped with anti-dazzle headlights, it is very likely to dazzle the driver of the vehicle, which is dangerous. Driver's driving safety

Although the anti-glare glasses can prevent the driver of the car from being dazzled, the driver must always wear the glasses, which brings great inconvenience to the driver, and the dazzling glasses cannot prevent strong light such as sunlight from entering the car. Therefore, the resulting aging of the interior cannot be suppressed or delayed
