Description
Technical field
The present invention relates to a kind of headlight for vehicle light lamp switching control of automatic identification, belong to the technology neck of car-mounted device
Domain.
Background technology
Car headlamp is the capital equipment of vehicle going at night, if headlamp brightness, beam angle are incorrect, by shadow
Ring driving at night safety.Therefore, head lamp bulb burn, be stained, irradiating angle abnormal, be all the phenomenon of danger close it is necessary to
Maintenance is repaired in time.
Headlight for vehicles includes high beam and dipped headlights, and the effect of distance light and dipped headlights is all used to illuminate vehicle front road
Road.Difference is, an irradiation near, an irradiation distant.Under normal circumstances, the irradiation distance of dipped headlights about 30-40 rice,
About 160 ° of range of exposures, high beam then more concentrate by light, and bright spot is big, can be irradiated to higher farther place.According to friendship
Logical law regulation, meeting at night should be away from contra, always dipped headlights be used in addition instead by 150 meters of car, in narrow road, narrow bridge and non-maneuver
Dipped headlights should be used during car meeting.Motor vehicles do not have street lamp, underlit or meet mist, rain, snow, sand and dust, ice at night
It should open headlamp, clearance lamps and rear lamp during the low visibility situation downward driving such as hail, but the rear car of equidirectional traveling with front
When car closely travels, high beam must not be used.Motor vehicles greasy weather traveling should open fog lamp and hazard warning lamp.
In vehicle travel process, do not note change lamp criterion during automobile meeting now with increasing driver, because
The angle of distance light too high it is easy to shake opposite car and the glasses of surrounding pedestrian, impact opposite pedestrian or vehicle in driver
Sight line, thus bring very big potential safety hazard to driving；This also results in the unsafe factor of more driving at nights, increases night
Between vehicle accident Probability.
In this regard, the different light handover control system of people's design improves.As application number：201610506706.4
The applying date：In the file of 2016-06-30, disclose a kind of vehicular high beam lamp unsteady state operation system, this system includes central authorities' process
Device and the photoconductive resistance module electrically connecting with central processing unit, WIFI module and distance-light switching circuit, vehicular high beam lamp is forced
Converting system by photoconductive resistance module judge this car whether be subject to high beam interference and by interference information be transferred to around other
The high beam unsteady state operation system of vehicle, this system has vehicle to be subject to high beam automatically that this car is remote in the case of disturbing around
Light lamp switches to dipped headlights, reduces and drives the situation that human factor error uses high beam, improves traffic safety.
And in an other application number：201410321776.3 the applying date：In the file of 2014-07-08, it is related to vehicle
Use headlamp.The problem of the present invention is, lighting of realizing suitably overtaking other vehicles in dim light lighting.The headlight for automobile of the present invention
Including:Light source portion, carries out the lighting of each lighting pattern of dipped beam lighting, distance light lighting and dim light lighting；Light sources
Portion, to light source portion for giving the lighting current of the corresponding current value of lighting pattern；Light distribution mechanism portion, is carried out according to lighting pattern
The luminous intensity distribution switching of the illumination light in light source portion；And control unit.When dim light lighting, control unit is carried out to the supply of light sources portion
Lighting current than current value low current value during dipped beam lighting.Dim light lighting is overtaken other vehicles instruction occasion, carry out to light source
Supply the lighting current of high current value, and luminous intensity distribution when carrying out distance light lighting in light distribution mechanism portion with power supply unit.
Although above-mentioned document makes improvement so as to switching can be automatically obtained to light handover control system, it is to avoid interference,
Reduce the situation misusing long-and-short distant light, but actually still suffer from deficiency.Existing light handover control system cannot be in conjunction with vehicle
Front traffic information, be automatically obtained the switching control to long-and-short distant light, only rely on and manually adjust or light sensing mode, do not have
Standby practicality, reduces the Automated condtrol effect of switching.
