Vehicle-mounted high beam weakening system

Abstract

The invention provides a vehicle-mounted high beam weakening system. An LED video glass is mounted on a vehicle front windshield and used for adjusting light intensity of the vehicle front windshield;and a main control device receives signals, which are transmitted by a light intensity monitoring device and a human eye positioning device, calculates a distance from a light source to the light intensity monitoring device and a distance from the human eye positioning device to a human face, calculates an included angle between the human eye positioning device and the light intensity monitoringdevice by using the distance from the light source to the light intensity monitoring device and the distance from the human eye positioning device to the human face, and then determines a distance from the light source to the human face to obtain the position of the light source on the vehicle front windshield, and controls the LED video glass to change color at a light source irradiated part so as to achieve an effect of reducing the intensity of the light source. The vehicle-mounted high beam weakening system has the advantages that the darkness of one parts, corresponding to human pupils, on the LED video glass is opened by using the light intensity received by human eyes so as to achieve a purpose of weakening the light source; and through pupil monitoring, whether a high beam directlyirradiates the eyes or not is effectively judged.

Description

technical field

[0001] The invention relates to a vehicle-mounted high-beam weakening system for automatically sensing light intensity and adjusting the darkness of a windshield. Background technique

[0002] A system and method for realizing anti-glare automobile high beams, the system includes a GPS data acquisition board, the GPS data acquisition board sends the collected data to a controller, and the controller controls the high beams on and off according to the data collected by the GPS data acquisition board The light transmission or opacity of the liquid crystal device can be controlled, and the liquid crystal device is connected with the driving circuit. When the high beam light of a car driving forward is illuminated, the forward square wave signal is at a high level, and the liquid crystal device transmits light. The driver can see the reflected light of the high beam light. The direction square wave signal is low level at this time, and its high beam is turned of...
