System and method for realizing anti-dazzling car high beam

Abstract

The invention discloses a system and method for realizing an anti-dazzling car high beam. The system comprises a GPS (Global Positioning System) data acquisition board, wherein the GPS data acquisition board sends acquired data to a controller; the controller controls an on / off state of a high beam and light transmittance or optical opacity of a controllable liquid crystal device; and the liquid crystal device is connected to a driving circuit. For the irradiation of a high beam of a positively driving car, a positive square wave signal is at a high electric level, the liquid crystal device is light-transmitting, a driver can see reflective lights of irradiative lights of the high beam, a driving car in an opposite side is an opposite driving car, an opposite square wave signal at a low electric level exists, and the high beam is turned off, so that the driver in the positive direction cannot see the lights of the high beam of the driving car in the opposite side and can see the road condition for safe driving. For the opposite square wave signal, the reverse is true. According to the system and method for realizing the anti-dazzling car high beam, the problem that the road condition cannot be seen clearly as the high beam must be turned off when cars meet at night is solved, the driver is allowed open the high beam when meeting with other cars at night, and the driver can see the road condition clearly and drive safely.

Description

technical field [0001] In particular, the invention relates to a system and method for realizing anti-glare automobile high beam. Background technique [0002] When cars meet at night, if the high beam is turned on, the other driver cannot see the road conditions clearly and causes danger; if the high beam is not turned on, the driver cannot see the road conditions clearly and causes danger. [0003] When meeting cars at night, the use of high beams is a big problem for drivers. In order to solve the above problems, predecessors have done a lot of work, such as application number 96106470.6, and the invention name is the backlight and sidelight background lighting anti-dazzling technology for meeting cars , the technical solution used in this application is that when two vehicles meet at night, the drivers of both sides turn on the rear lights and side lights to implement background lighting while switching to the near lights, so as to illuminate their own car body and the r...

Problems solved by technology

Can cause difficulty seeing the road due to inability to use high beams

[0008] Utility model patent, patent number 201120572731.5, a kind of anti-glare glasses for meeting cars at night, through the polarizer of the glasses, the light of the other party is weakened to achieve the purpose of anti-glare, but while weakening the high beam light of the other party, it also weakens the impact of road conditions Effective light, can't see the road clearly
