Problems solved by technology

During this time of about 2 seconds, the driver seems to be driving with his eyes closed, and his ability to observe the surrounding environment is greatly reduced, which is not conducive to the driver's safe driving.
In addition, when the vehicle is driving at night, the light of the high beam of the rear vehicle will shine on the rearview mirror inside and outside the car, and the strong light will be reflected on the driver's eyes, which will also cause the driver to be instantly dazzled and affect the safety of the driver. Line of sight, especially when the car is driving at high speed, will greatly increase the braking distance, seriously affecting the safety of driving at night

Abstract

The invention discloses an anti-dazzle device, a control method thereof and a vehicle thereof. The anti-dazzle device comprises a discoloration thin film, an acquisition module, a processing module and a control module, wherein the discoloration thin film is arranged on the light path between high beams outside the vehicle and human eyes; the acquisition module is used for acquiring information about the pupils of the human eyes and information about the external high beams; the processing module is used for determining a dazzling area on the discoloration thin film; the control module is usedfor reducing the intensity of light entering the human eyes through the dazzling area by controlling the discoloration thin film according to the dazzling area. The anti-dazzle device has the advantages of avoiding the impact of vehicles' external high beams on a driver, prevent the driver from dazzling, and improving the safety of night driving. Further provided is the control method of the anti-dazzle device and the vehicle of the anti-dazzle device.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an anti-glare device, a control method thereof, and a vehicle. Background technique [0002] When a vehicle is driving at night, it usually uses high beams to see the road ahead. When meeting cars, the high beams of the oncoming vehicle will greatly stimulate the eyes of the driver, causing the driver to be instantly dazzled. Depending on the driver's own vision and the surrounding environment, the duration of the glare is also different, but the duration of the glare is at least about 2 seconds. During this time of about 2 seconds, the driver is driving with his eyes closed, and his ability to observe the surrounding environment is greatly reduced, which is not conducive to the driver's safe driving. In addition, when the vehicle is driving at night, the light of the high beam of the rear vehicle will shine on the rearview mirror inside and outside the car, and the stro...
