CTOnews.com, November 24, with the increasing intelligence of cars, car companies have begun to delve into a variety of detailed functions, through technical means to solve some of the current driving problems.

According to Aiqi, recently, the patent for "anti-glare device and control method" applied by Hezhong New Energy Automobile Co., Ltd., an automobile affiliated company, was announced.

According to the summary, the patent includes an electrochromic lens, an information collection module and a control module.

The surface of the electrochromic lens is within the driver's line of sight in the car.

The information acquisition module includes a light intensity sensor, an infrared light source and an infrared camera. The light intensity sensor is used to obtain the light intensity on the mirror side of the electrochromic lens, and the infrared light source is used to emit infrared light to the driver. The infrared camera is used to obtain the micro-expression image of the driver.

The control module controls the discoloration of the electrochromic lens according to the squinting degree of the human eye in the micro-expression image. When the squinting degree is more serious, the electrochromic lens becomes darker.

In addition, according to the contents of the patent specification, by setting the rearview mirror as an electrochromic lens, the light intensity behind the car is detected by the light intensity sensor, and when the light intensity at the rear of the car is large, the electrochromic lens is controlled to darken, in order to reduce the driver's eyes stimulated by strong light.
