Method and device for preventing glare of high beam of intelligent rearview mirror

Abstract

The embodiment of the invention discloses a method and device for preventing glare of a high beam of an intelligent rearview mirror, and relates to the technical field of vehicle-mounted equipment. According to the main purpose of the method and device for preventing glare of the high beam of the intelligent rearview mirror, the reflective effect of the intelligent rearview mirror is dynamically adjusted according to change of light rays so as to meet observing needs of drivers in different driving environments. The method for preventing glare of the high beam of the intelligent rearview mirror comprises the steps that whether a glare preventing mode is started or not is judged according the environment light ray intensity inside and outside a vehicle, and the glare preventing mode refersto utilize voltage to control a light valve liquid crystal layer in a mirror surface of the intelligent rearview mirror so as to adjust the light transmittance and the reflected light intensity of theincident light ray; if the glare preventing mode is started, loading voltage of the light valve liquid crystal layer is adjusted according to the intensity value of the light ray; and if the glare preventing mode is not started, the loading voltage value of the light valve liquid crystal layer is kept to zero.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle equipment, and in particular to a method and device for preventing glare from high beam lamps in a smart rearview mirror. Background technique [0002] When the driver is driving at night, he often encounters the situation that the rear car turns on the high beam for a long time, so that the rearview mirror is covered by dazzling glare. It can cause discomfort to the driver's eyes, and even lead to night blindness or white spot effect, thereby increasing the risk of driving accidents. [0003] The existing traditional rearview mirror realizes the anti-glare effect by manually adjusting the double-reflecting mirror surfaces (high and low reflectivity). However, the smart rearview mirror needs to integrate complex hardware function modules, especially the user interface needs to be displayed on the mirror surface through the liquid crystal module to realize more complex functi...

Problems solved by technology

However, the smart rearview mirror needs to integrate complex hardware function modules, especially the user interface needs to be displayed on the mirror surface through the liquid crystal module to realize more complex functions in addition to the traditional rearview mirror functions.

This makes the anti-glare technology of existing traditional rearview mirrors unable to be used in smart rearview mirrors

[0004] However, the anti-glare technology adopted by the existing intelligent rearview mirror is mainly realized through the blue coating mirror surface, and its blue coating utilizes the strong absorption of blue light on the orange, yellow and other parts of the visible light with low color temperature. The brightness of the overall reflected light is reduced to achieve the anti-glare effect. However, the overall color of the mirror is blue, which makes the driver feel that the mirror is dark when used in the daytime, which affects the effect of the rearview mirror in the daytime.
