Description
Technical field
The present invention relates to field of automobile, particularly the automatic anti-glare system of a kind of vehicle front windshield glass.
Background technology
Vehicle needs to open front car light and throws light on, in most of the cases when night running, open passing light and can satisfy the lighting demand that travels, the interim country beam of opening throws light under underlit situation, when there are normal driving vehicle or meeting in the place ahead, should in time switch to passing light; And the part chaufeur causes the subtend chaufeur dazzling because carelessness or shortage awareness of safety are still opened country beam during meeting, and traffic accident very easily takes place.On the existing vehicle, also not at the safeguard procedures of this situation, open dazzling that country beam causes for opposed vehicle, only can rely on driver's experiences to carry out " blind " operation, dangerous hidden danger is very big.
In the prior art, for fear of the generation of dazzling phenomenon, and integral body is used flash glass, but has reduced the light transmittance of front windshield glass, makes chaufeur be difficult for seeing clearly road conditions in the ordinary course of things, the generation that still causes the accident easily; Therefore, current urgent need is a kind of can to guarantee normal printing opacity generally speaking, and can prevent effectively that when high light occurs the dazzling device of chaufeur from guaranteeing traffic safety.
Summary of the invention
The technical problem to be solved in the present invention provides the normal printing opacity of a kind of front windshield glass generally, and can prevent timely and effectively that strong illumination is to the automatic anti-glare system of the vehicle front windshield glass of the eyes of chaufeur when high light occurs.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of vehicle front windshield glass automatic anti-glare system, comprise the place ahead vision module, operator's compartment vision module, control module and anti-glare module;
Described the place ahead vision module is used for position and intensity that monitoring enters front windshield glass light;
Described operator's compartment vision module is used for monitoring driver's eyes position;
Described anti-glare module is arranged on the front windshield glass, is used for adjusting the light and shade variation of front windshield glass;
Described control module, be connected with the place ahead vision module, operator's compartment vision module and anti-glare module, be used for to receive that described the place ahead vision module and operator's compartment vision module send monitor signal, and control described anti-glare module according to the monitor signal that receives, the light and shade that makes described anti-glare module adjust front windshield glass changes.
In technique scheme, control module is determined intensity and the position of vehicle front light source to determine the driver's eyes location information by the information of reception operator's compartment vision module by the light source information that receives the place ahead vision module; Determine and to need deepening to carry out the position that light blocks in anti-glare module by the analysis in the control module and computing, and then control the interior liquid crystal lattice of anti-glare module in this position deepening or blackening, thereby realize anti-glare function.Therefore, the present invention not only can guarantee the normal printing opacity of front windshield glass generally speaking, and can prevent strong illumination timely and effectively to the eyes of chaufeur when high light occurs, thereby effectively avoids the dazzling and then assurance traffic safety of chaufeur.

The specific embodiment
For making can not be the automatically anti-glare technical scheme of vehicle front windshield glass in the prior art that the present invention will solve clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, present embodiment provides a kind of vehicle front windshield glass automatic anti-glare system, comprise the place ahead vision module 2, operator's compartment vision module 3, anti-glare module 1 and control module 4, control module 4 is connected with the place ahead vision module 2, operator's compartment vision module 3 and anti-glare module 1; And for example shown in Figure 2, described anti-glare module 1 is arranged on the front windshield glass position, comprises being arranged at the interbedded liquid crystal lattice net 11 of front windshield glass, and described anti-glare module can be carried out the variation of the light and shade of zones of different; The place ahead vision module 2 is used for monitor vehicle the place ahead light source position and intensity, and monitor signal is transferred to control module 4.
As shown in Figure 3, the place ahead vision module 2 of present embodiment mainly is made up of two cameras forward, described the place ahead vision module is in the night travel process, owing to have certain distance between two cameras, thereby the image difference of two cameras about can passing through, analysis meter is calculated the approximate location of front vehicles light source; Described the place ahead vision module 2 is converted to gray level image with the place ahead situation, by light source gray value and speck zone, can judge intensity and the size of light source; Described operator's compartment vision module 3 is used for monitoring chaufeur eyes position, described operator's compartment vision module 3 is made up of the camera that has face identification functions, described operator's compartment vision module passes through face identification functions, chaufeur eyes position is positioned, and the information of monitoring is passed to described control module 4 in real time; Described control module 4 is used for the information that described the place ahead vision module 2 and described operator's compartment vision module 3 transmit is received and analyze computing, and controls described liquid crystal front windshield glass and produce light and shade in the specific region and change.Described liquid crystal front windshield glass 1 keeps complete pellucidity under the situation of not receiving the control information that described control module 2 sends; When described liquid crystal front windshield glass receives corresponding control information, then control self deepening of corresponding position or blackening.
As shown in Figure 4, control module 4 is positioned over vehicle front light source 12 positions in the virtual coordinate system, and positions by receiving the light source information of the place ahead vision module 2; Control module 4 is by receiving the information of operator's compartment vision module 3, is positioned over chaufeur eyes position 13 in the same virtual coordinate system and positions; In control module 2, vehicle front light source 12 is carried out line between chaufeur eyes position 13, the zone that this line segment and front windshield glass intersect, namely need on front windshield glass, blackening carry out the position that light blocks, control module 4 is controlled by the winding displacement at anti-glare module 1 edge again, make to manifest liquid crystal lattice deepening zone 14 in the anti-glare module 1, thereby realize anti-glare function.
In the above-described embodiments, described control module also can receive vehicle front light source position and the strength information that other sensors provide in the car, is used for the described anti-glare module of control.
The technical scheme of the embodiment of the invention not only can guarantee the normal printing opacity of front windshield glass generally speaking, and can be when high light occurs, can prevent strong illumination timely and effectively to the eyes of chaufeur, thereby effectively avoid the dazzling and then assurance traffic safety of chaufeur.
