Abstract
The present invention relates to a kind of vehicle front-viewing intelligence anti-dazzle system based on electrochomeric glass, including the human eye positioner of the position for catching driver's eyes, for identifying the light source locating device of the locus of vehicle front each point；Human eye positioner and light source locating device are all connected with processing module, and processing module connects driving module, drive module to send signal of telecommunication control electrochomeric glass driver drives electrochomeric glass and carry out non-glare treated.Advantages of the present invention: the anti-dazzle system that the present invention provides, it it is the locus being determined intense light source and human eye by infrared signal and image information, the electrochomeric glass of automatically controlled variable printing opacity, accurate shading is realized by dot matrix techniques, the visual field in other regions, driver front is not disturbed realizing anti-dazzle while, it is prevented effectively from the generation of danger, also reaches the requirement that the transmitance that automobile night driving security technology standard specify is more than 75% simultaneously.
Description
Technical field
The present invention relates to automobile anti-dazzle technical field, particularly relate to a kind of big for driving at night elimination opposite vehicle
Lamp dazzle and day driving shading, eliminate the impact of dazzle, it is ensured that the anti-dazzle system of vehicle front-viewing intelligence of traffic safety
System.
Background technology
The dazzle of automobile night driving meeting is key factor and the major issue affecting traffic safety, especially before
An illuminator light side on the weak side, under the other side's headlamp acute irradiation, forms blind area in Vehicle during Crossing Event, sees at all
Less than the road conditions of one's own side, abnormally dangerous, the most therefore there are major traffic accidents.Even if both sides use
Far and near lamp changing method reduces the impact of headlamp, but dazzle still exists, and affects traffic safety.
In order to solve this problem, people study and devise a lot of solution, such as, transform front car light,
Use polaroid, design anti-dazzle spectacles；Design several shading mirror for block respectively dazzle in various degree and
Daylight；Reflector, coated glass, LCD screen are transformed to visual area by design automaton when needed, not
Time the most manually or automatically reset；Design electrochromic device loads to visual area, and these patents of invention such as have
CN1664441A, CN85203634U, CN2640804Y, CN201009814Y, CN2811046Y etc..These
Scheme serves certain effect, but owing to being restricted by following factors, it is difficult to promote: 1, in anti-dazzle sight
The intersection in Cha Qu and non-anti-dazzle district forms bigger sight equation, distinguishes road conditions and judges there is the biggest shadow
Ringing, whether 2, the space installing needs of antiglare equipment and position are met, the especially front of car
Wind glass is the least to the space between driver, is not suitable for the device that mounting structure is big and complicated；3, reliable
Degree problem, if antiglare equipment is the most complicated, Maintenance Difficulty, reliability declines, and the most malfunctioning becomes uneasy on the contrary
Total factor.And for example patent CN1736745A and CN2811046Y, uses a kind of liquid crystal presenting stepped change to become
Color is in the light pattern, but owing to being step condition, there is sudden change demarcation line, causes the discontinuous of visual scene and regards
The discomfort felt, being easily generated visual determination mistake affects safety on the contrary.And for liquid crystal color-changing screen, it becomes
After light, light itself is to present scattering state, if being not added with polarized light piece, sight line just thickens, and sees whatever
Not knowing, result has been kept off light and has also been kept off sight line；If having added polarized light piece, passing through when pellucidity
Rate is substantially reduced, low to less than 50%, does not reaches the transmitance that automobile night driving security technology standard specifies
Requirement more than 75%.Also has patent CN103909869A, although use electrochomeric glass to make light transmittance reach
To requiring, but the overall dimmed meeting of glass transmission rate causes night the most dim place darker, drives
Member will be unable to judge.
Electrochromic device structure is that the five-layer structure of sandwich type is: " glass/transparency conducting layer (ITO)/
Electrochromic layer (EC)/ion conductive layer (IC)/ion storage (CE)/transparency conducting layer (ITO)/glass
Glass " structure.As it is shown in figure 1, in addition to first substrate glass and second substrate glass, five-layer structure is respectively
Bright conductive layer, EC layer (electrochromic layer), ion conductor layer, ion storage and transparent ion conductive layer,
Wherein EC electrochromic layer is core, and ion conductor provides ion transmission channel between electrochromic layer,
Ion storage layer plays ion storage, the effect of balancing charge, also referred to as ion implanting electrode.When adding at conductive layer
After upper forward dc voltage, ion storage layer intermediate ion is drawn out of, and by ion conductor, enters electrochromic layer,
Cause photochromic layer variable color, it is achieved idle hold mode, be embodied with memory function.When plus backward voltage,
Electrochromic layer intermediate ion enters again storage layers after being drawn out of, whole device recovers transparent original state.Electrochromic layer
Dividing again mineral-type and organic-based material, inorganic matter is transition metal oxide or hydrate, with WO3For main generation
Table, such as United States Patent (USP) U.S.Patents Nos.5,598293,6,005,705 and 6,136,161, another
Class is organic electrochromic material, point mainly have from structure various organic heterocyclic molecule such as bipyridyl salt,
Conducting polymer species, organometallic polymer class and metal phthalocyanine class, such as U.S.Patents
Nos.7,038,828,7,064,882,7,547,658, they without exception be all five-layer structure.And it is right
In the electrochromic layer of organic, glass/ITO (transparency conducting layer) and EC (electrochromic layer) Presence of an interface
In conjunction with problem, its characteristic combined directly affects the key performances such as the cycle life of EC, compactness and uniformity.
Owing to ITO material is a kind of inorganic oxide i.e. indium tin oxide material, organic electrochromic EC will be on its surface
Upper film forming, constitutes nanoscale stratiform structural material, relies solely on superficial attractive forces and be difficult to maintain its durability,
The film layer even forming even compact is the most extremely difficult.
