Description
Technical field
The present invention relates to LED car lamp field, especially a kind of method of high beam anti-dazzle.
Background technology
It is well known that high beam irradiation distance is farther, brightness higher can improve the security of driving in special road section,
But dazzle is caused in the place that high beam can irradiate front simultaneously.High beam is abused during existing many driver drivings, it so can be right
Other people or meeting impact, and there are some potential safety problemss.To avoid the dazzle of high beam, it is necessary to be added in headlamp
Anti-dazzle photosystem, existing anti-dazzle system structure are complicated.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of method of high beam anti-dazzle, for avoiding high beam institute
Caused by dazzle, it is and simple in structure.
In order to solve the above technical problems, the technical scheme is that：A kind of method of high beam anti-dazzle, based on it is anti-
Dazzle system include light source detection system and it is corresponding with left headlight and right headlight respectively cut electro-optical device, it is described to cut electro-optical device
Including mounting base, for drive installation seat shaft, be arranged in mounting base cut mating plate and for control shaft rotation make to cut
The stepper motor that mating plate moves in high beam range of exposures；The light source detection system includes camera, the control of vehicle body center
System, left lamp dimming control system and right lamp dimming control system, camera are connected by CAN bus and vehicle body central control system
It connects, vehicle body central control system is connected by LIN buses with left lamp dimming control system and right lamp dimming control system respectively, institute
It states left lamp dimming control system electro-optical device of cutting corresponding with left headlight to connect, the right lamp dimming control system is corresponding with right headlight
Cut electro-optical device connection；Anti-dazzle step：
（1）System starts to initialize；
（2）Whether vehicle body central control system automatic decision has detected opposite car light source, if so, entering step（3）,
If it is not, then continue to detect；
（3）Vehicle body central control system carries out vehicle calibration to the light source detected；
（4）The distance and angle of demarcating vehicle are calculated by the information of camera；
（5）Distance and angle calibration system and optimization to calibration vehicle；
（6）Vehicle body central control system carries out data preparation；
（7）Vehicle body central control system transfers data to left and right lamp dimming control system by LIN buses；
（8）It cuts the stepper motor of electro-optical device and mating plate cut according to data-driven rotates by a certain angle to perform and relevant cut light processing.
As an improvement, the mounting base includes installing plate and setting, mounting ear, the mounting ear are equipped on a mounting board
Perforation, the shaft pass through the perforation.
The caused compared with prior art advantageous effect of the present invention is：
When light source detection system detects the light source for far carrying out vehicle on opposite, electro-optical device is cut in startup, and mating plate is cut in stepper motor drive
It rotates by a certain angle, cuts mating plate and be just emitted onto the light of opposite light source range and block, so as to prevent causing dazzle to carrying out vehicle；
The angle of stepper motor rotation is accurate, can accurately control the irradiation area for cutting mating plate excision.
Description of the drawings
Fig. 1 is to cut electro-optical device structure diagram.
Fig. 2 is light source detection system block diagram.
Fig. 3 is anti-dazzle flow chart.
Specific embodiment
With reference to Figure of description, the invention will be further described.
A kind of anti-dazzle photosystem of high beam, it is including light source detection system and corresponding with left headlight and right headlight respectively
Cut electro-optical device.
As shown in Figure 1, the front cut electro-optical device and be arranged on vehicle lamp light source 4, pacifies including mounting base 1, for driving
The shaft 2 of seat 1 is filled, is arranged in mounting base 1 and cuts mating plate 3 and for the rotation of shaft 2 to be controlled to make to cut mating plate 3 in distance light light irradiation
In the range of the stepper motor that moves（It does not indicate）.The mounting base 1 includes installing plate and sets mounting ear on a mounting board, described
Mounting ear is equipped with perforation, and the shaft 2 passes through the perforation.The one side for cutting mating plate 3 is arcwall face.The stepper motor
Output shaft pass through gear set drive shaft 2.This is simple in structure, can be reached with fast accurate and specify irradiation area.
As shown in Fig. 2, the light source detection system includes camera, vehicle body central control system, left lamp brightness adjustment control system
System and right lamp dimming control system, camera are connected by CAN bus with vehicle body central control system, vehicle body central control system
It is connected respectively with left lamp dimming control system and right lamp dimming control system by LIN buses, the left lamp dimming control system
Corresponding with left headlight to cut electro-optical device connection, the right lamp dimming control system is corresponding with right headlight to cut electro-optical device connection.It takes the photograph
As effect of the head in Vehicle during Crossing Event be that acquisition opposite vehicle or front vehicles relative position and movement velocity and
Other need information, transmit data to vehicle body central control system in real time by CAN bus；Then central car body controller according to
These information calculate vehicle location, and related data is sent to left lamp dimming control system again by LIN buses and right lamp dims
