An automotive anti-glare system and method

Abstract

The invention discloses an automobile anti-dazzling system and method. The automobile anti-dazzling system comprises a light sensing device, a human eye recognition device, an information processing device and a liquid crystal layer. The light sensing device and the human eye recognition device are electrically connected with the information processing device, the information processing device iselectrically connected with the liquid crystal layer, the light sensing device is used for obtaining the light intensity of a plurality of points on the surface of the liquid crystal layer, the humaneye recognition device is used for obtaining the positions of eyeballs, the information processing device is used for obtaining light intensity distribution on the surface of the liquid crystal layerand the light source angle according to the light intensity information of the multiple points on the surface of the liquid crystal layer, and determines a strong dazzle area by combining with the positions of the eyeballs, and meanwhile, deflection of liquid crystal molecules in the strong dazzle area on the liquid crystal layer is controlled so as to adjust the light transmittance of the liquidcrystal layer. The invention further discloses an automobile anti-dazzling method at the same time. The strong dazzle area is determined in real time, the deflection amount of the liquid crystal molecules is adjusted, thus the light transmittance of the liquid crystal layer is changed, and the anti-dazzling effect is achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an anti-glare system and method for an automobile. Background technique [0002] Nowadays, with the gradual increase of vehicles and the limited supervision of relevant laws and regulations, the phenomenon of abuse of high beams is very common in our country. According to the survey, more than 70% of drivers on urban roads at night turn on their high beams under inappropriate conditions, and nearly 80% of drivers expressed their disgust and concern about the glare caused by high beams. [0003] At present, car drivers usually stick anti-glare film or wear sunglasses to solve the problem of strong light shining directly on the eyes. Eye exposure, when the light is strong, can not avoid the stimulation of human eyes. Moreover, the anti-glare film is passive anti-glare, which will affect the line of sight when the light is dark, causing safety hazards, and the situation where the driver ...

Problems solved by technology

[0003] At present, car drivers usually stick anti-glare film or wear sunglasses to solve the problem of strong light shining directly on the eyes. Eye exposure, when the light is strong, can not avoid the stimulation of human eyes

Moreover, the anti-glare film is passive anti-glare, which will affect the line of sight when the light is dark, causing safety hazards, and the situation where the driver removes or wears sunglasses during driving is also an unsafe factor

[0004] In the existing technology, there are still many technical defects in the traditional interior and exterior rearview mirrors: the interior and exterior rearview mirrors in the prior art do not have anti-glare function, and the anti-glare effect is mainly achieved by manually adjusting the interior and exterior rearview mirrors to change the light reflection angle When the driver is driving at night, the headlights of the vehicle behind may puncture the driver's eyes through the interior and exterior rearview mirrors. When the driver manually adjusts the interior and exterior rearview mirrors, it is easy for the driver to ignore the operation or it is difficult to deal with emergencies , likely to cause traffic accidents

[0005] In the existing anti-glare technology, there is also a photosensitive diode that senses the intensity of light to pressurize the ionosphere of the glass mirror to make its color darker and achieve the anti-glare effect. However, this technology has an active anti-glare effect. However, reducing the overall brightness and visibility, especially in the dark night road and when reversing, the sight becomes worse, which is likely to cause accidents
