Car lamp distance and passing light automatic converting device in car meeting at night and method thereof

Abstract

The invention discloses a car lamp distance and passing light automatic converting device in car meeting at night and a method thereof. The device comprises a light intensity recognition module for collecting the light intensity of car lamps of a coming car in car meeting, a light source judgment module and a car lamp control module, wherein the light source judgment module is connected with the light intensity recognition module and used for comparing the collected light intensity with a first threshold value so as to generate a control signal, the first threshold value is the set and allowable light intensity maximum value of the car lamps of the coming car when the naked eyes can see the road condition clearly, and the car lamp control module is connected with the light source judgment module and used for controlling car lamps of a car of a user to conduct conversion of flickering and distance and passing light according to the generated control signal after the light source judgment module completes judgment. The device can detect the light intensity of the car lamps of the coming car in car meeting and judge whether the intensity exceeds a limiting threshold value or not, if the intensity exceeds the limiting threshold value, the car lamps of the car of the user is arranged to be passing light, meanwhile, the coming car is prompted through the car lamp flickering mode, and therefore the car running environment can be improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic conversion device and method for far and low beams of vehicle lights when meeting vehicles at night. Background technique [0002] At present, with the improvement of people's living standards, cars have quickly entered the families of ordinary people, and the occurrence of traffic accidents has become more and more common. According to statistics, nighttime traffic accidents account for more than 60% in traffic accidents, and dazzling high beams are one of the chief culprits causing high incidence of nighttime traffic accidents, so it is urgent to provide a method that can solve the above problems. [0003] At present, there are many methods of anti-glare for meeting cars at night. Based on their ideas, there are mainly the following situations: (1) Use mechanical equipment to change the position of the headlights, so as to realize the conversion of low beam and hig...

Problems solved by technology

In the first way, due to the use of mechanical equipment, its response time is not timely enough. At the same time, after a long period of time, it will cause the aging of the mechanical equipment, which will affect its accuracy; At the same time, it is relatively simple to implement a polarizer on the headlights, but the polarizing film is a consumable product, and the car is in a high-dust, high-temperature, high-humidity enviro
