Description
Technical field
The present invention relates to high beam control field, more particularly to a kind of dazzle light to force switching device.
Background technology
High beam is illuminating to vehicle travel at night, and in general, light is more bright better, and when two opposite travelings
Vehicle when meeting at night, driver should switch high beam in time is dipped headlight, avoids influenceing opponent vehicle driver
Normal line of sight.And in reality, the driver always having has the situation that vehicle approaches near without switching in time in face of opposite
Light lamp does not switch dipped headlight even, opposite vehicle driver because can not correctly be judged surface conditions by high beam strong illumination,
Cause danger.In recent years, accident was more and more caused by the incorrect use of dazzle light, wanted to reduce such thing
Therefore frequency, while traffic administration dynamics is strengthened, it is also a kind of effective side to install some auxiliary equipments additional in vehicle
Method.
At this stage to dazzle light control research be mainly：1st, antidizzy headlight with main beam for vehicle.Automobile anti-dazzle is remote
Light front lamp anti-glare is to adjust the angle of filament and the plane of reflection, make light will not direct irradiation driver eyes.But
When meeting, the sight of people automatic can obtain light by headlight and attract, so high beam dazzles the eyes problem to still have.
2nd, with polarised light anti-glare.Polarised light abblendbar principle is the polarization characteristic with light, and the windshield of vehicle is changed into partially
Shake piece, and its polarization axle also changes polarizer into the horizontal positive 45 degree of angles, lamp lens, and its polarization axle is with the horizontal minus 45

This scheme not yet reaches degree of being practical.3rd, monochromatic light is anti-dazzle.Anti-dazzle monochromatic light is illuminated using monochromatic high beam.Research hair
Existing, during saturation lighting, human eye has more more sensitive than white light to gold-tinted, and the time ratio that eye dazzles the eyes rearward vision to recover by gold-tinted is white
The time that light recovers after dazzling the eyes is short, can strive for the quality time when emergency occurs.But yellow wavelengths are smaller, generally
Illumination efficiency is low, and the visual field does not work, and effect is less desirable, so being not widely used.4th, liquid crystal device for changing light.Liquid crystal darkening
The general principle of anti-dazzle apparatus is the liquid feeding crystal panel before car light, and extraneous intensity of illumination is detected using sensor, then will be passed
The signal input control chip that sensor obtains, control chip change the transmissivity of liquid crystal according to extraneous light conditions, make car light
Light dies down, and solves the dazzling problem of high beam.At present the problem of, is that the cost of system is high, and the heat-resistant quality of liquid crystal is poor, the life-span
Do not grow, be also not widely used.
Being found by the analysis to research conditions, the solution of most dazzling problems of high beam all be present,
The problems such as having plenty of that cost is high, the immature and existing automotive system of scheme can not be docked smoothly etc., and according to actual conditions need
Ask, for dazzle light detection and control system, there must be low cost, easily promote, fast, highly reliable spy of coming into force

Structure, and arc-shaped cover be provided at both ends with the first signal outlet can secondary signal outlet.Referring to Fig. 7, because system is Anonymous communication,
Both sides do not know partner address before sending and receiving message, so, it is dipped beam that recipient, which receives signal to switch the headlight of oneself at once,
Lamp, the address of oneself of getting along well compare.This brings a problem, the direction of propagation of signal, because signal projector is sent simultaneously
Signal be diverging, do not do signal polymerization processing can influence around the vehicle unrelated with Vehicle during Crossing Event, so, utilize wireless communication
The characteristics of number can not passing through metal, this secondary design devise one and prevent signal and the unrelated directional divergence of Vehicle during Crossing Event, thirdly
Tie up profile as shown in the figure.Wireless transmission is placed on the signal aggregation apparatus center of circle, signal will with certain dispersion angle to
Front is launched, and without being dissipated to surrounding, influences the normally travel of other unrelated vehicles.
Dazzle light of the present invention based on wireless telecommunications forces switching system, and wireless telecommunications are established between two cars, with
Single-chip microcomputer is core, and light sensor is detection, and wireless telecommunications are exchange program, using optical sensor detection front come car
High beam, when intensity of illumination reaches certain value, system identification front is carried out car and had an impact to current driving vehicle, then sends nothing
Line signal informs other side, after receiving signal on opponent vehicle, high beam will be switched to dipped headlight, reach active control
Purpose, solve and common in life form vision due to receiving vehicle high beam irradiation driver's eyes in opposite in startup procedure
Blind area can not correctly judge above section situation, the problem of causing danger.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
