Description
Technical field
Car light field is the utility model is related to, specifically, the utility model is related to a kind of intelligent vapour with complex function
Car headlight module, the intelligent automobile headlight module with complex function is by auto bulb illumination high-resolution headlight and half
Conductor Laser element (laser radar transmitter) is composed, and tri- kinds of intelligence of AFS, ADB and ADAS are realized by a set of optics module
Function.
Background technology
With vehicle travel at night, security issues become increasingly urgent, and more and more automakers are in research and development novel intelligent car
Lamp technology.So-called novel intelligent car light technology is mainly to realize that (follow-up steering headlight, is also referred to as adaptive headlight to AFS
(Adaptive Frontlighting System), follow-up steering headlight can constantly to headlight carry out dynamic regulation, keep with
The current driving direction of automobile is consistent, to ensure that driver is owned by optimal visibility at any time.
Common headlight has fixed range of exposures, when night automobile is being turned on bend, due to that can not adjust illumination
Angle, usually " blind area " can occurs in curve inner side, thus greatly threaten the safety driving tips at driver's night.And AFS (with
Dynamic steering headlight) can be according to the deflection of the automatic adjustment headlight such as road speed, steering angle, so as to illuminate in advance " not
The region of arrival ", there is provided comprehensive emergency lighting, to ensure that driver is owned by optimal visibility at any time.
It is dazzling to easily cause driver for high beam abuse when on the other hand, because meeting at night, so that traffic accident is caused, ADB
Intelligent headlight can lift the security that meets at night.The adaptive distance light systems of ADB are by camera, sensor, electronic control unit, preceding
Illuminator, image processing system, hardware processor are formed, and can be detected the other vehicles of road or the position of pedestrian, distance light is existed
Dark space is produced in relevant position automatically during meeting, so that it is dazzling to produce other side, lifts the security that meets at night.
In addition, in order to further enhance vehicle drive security, occur ADAS (Advanced Driver so far
Assistance System, Senior Officer's auxiliary system) in addition advanced autonomous driving system demand.
Image recognition is an important ring of ADAS, but night is influenced visual light imaging difficulty by illumination deficiency, and only installation is taken the photograph
It is difficult to realize as the auxiliary such as FCW, LDW of ADAS systems of head and processor drive function.Moreover, merely from increase camera
CMOS performances solve the problems, such as that this adds cost and effect is limited with increase pixel, and ADB intelligent headlights system can lead to
Overregulating colour temperature and distance-light angularly strengthens illumination, and therefore, ADB intelligent headlights can lift the knowledge of ADAS systems nighttime image
Other ability.
For example, coordinating the detection system of vehicle, there is the headlight of ADB, other participants on road are found in detecting
When in a certain section in headlamp illumination, the brightness of illumination in the adjusting section that system can be intelligent even directly closes the region
Illumination, an independent local dark space being formed in integral illumination space, dazzles to avoid danger is formed to illuminated person
Mesh.Meanwhile continue to keep the illumination of high brightness in the space without other roads participant., can according to above-mentioned technical support
Ensure the high quality illumination of our (carry LED adaptive headlights) vehicle front, but will not to other participants on road (such as
In opposite directions, vehicle travelled in the same direction etc.) the dazzling of danger is formed, it ensure that the nighttime driving safety of each side on road.
ADAS (Advanced Driver Assistance System, Senior Officer's auxiliary system) in addition it is advanced from
Main driving system requirements are required for the support of high-precision vehicle forward looking detection ability.Forward-looking laser radar is exactly that one kind is closed very much
Suitable sensor plan.
After the appearance of ADAS system schemas, also for lifting driving safety, also it has been proposed that such technical solution：
Some are projected on road surface and drives closely bound up information alert, for example speed is reminded, pedestrian position is reminded and navigation hint
Deng with the theory of augmented reality, alloing driver more intuitively to obtain the information alert for surmounting eye detection ability.
So far, three of the above technology, i.e. AFS, ADB and ADAS are independent mutually, are mounted in tool if desired
On body vehicle, then three sets of independent devices are needed to be installed on vehicle, each to realize its set function.
For example, Chinese Patent Application No. " 201610958902.5 ", " the one of PCT Application No. " PCT/CN2017/074197 "
Kind novel intelligent car light module " and Chinese Patent Application No. " 201610962328.0 ", PCT Application No. " PCT/CN2017/
A kind of 074200 " " high-resolution headlight for vehicles optics module and its high-resolution far lighting control method " patent is respectively
Respective realize of AFS, ADB function proposes technical solution.But it is not directed to ADAS functions.
