Problems solved by technology

However, when the electrochromic automatic anti-glare rearview lens operates to reduce the reflectivity, it will also cause the screen transmittance of the display unit behind the electrochromic to decrease and affect the brightness of the screen.

Abstract

The invention provides a rearview mirror controlling method and a rearview mirror controlling system. A rearview mirror comprises an electrochromic component and a displaying unit. The rearview mirror controlling method comprises the following steps of determining whether a first glare value of the rearview mirror exceeds a preset glare threshold value or not; determining a first temperature value of the electrochromic component when the first glare value of the rearview mirror exceeds the preset glare threshold value; determining a first voltage value of the electrochronic component according to the first temperature value and the first glare value; determining a penetrating rate changing curve of the electrochromic component according to the first voltage value and the first temperature value; and adjusting the backlight brightness of the displaying unit over time to compensate the displaying brightness of the displaying unit according to the penetrating rate changing curve.

Description

technical field [0001] The invention relates to the control of rearview mirrors, in particular to a method for controlling rearview mirrors and a control system for rearview mirrors. Background technique [0002] When driving at night, if the rear car is too close or the rear car turns on the high beam, it will cause the rearview mirror to reflect strong light, cause the driver's visual discomfort, and even cause the driver's short-term vision loss. Even if the strong light disappears, due to the effect of residual vision, there will be blind spots on the driver's retina, thus affecting the driver's ability to respond. Such residual visual phenomenon can last as long as 1.4 seconds, which is the Troxler Fading Effect (Troxler Fading Effect). Effect). If driving at a speed of 100 kilometers per hour, the vehicle has traveled about 38 meters in 1.4 seconds, which is a potential danger of accident. The automatic anti-glare rearview mirror can avoid affecting the driver's reac...
