Abstract
The invention discloses an automatic guide board lighting system based on a geometrical multi-beam LED lamp. A high-beam lamp assembly is composed of a plurality of high-beam LED lamp beads which are arranged in a matrix mode, a lamp bead controller selects a set of the high-beam LED lamp beads of which the irradiation range can exactly cover the transverse irradiation range and the longitudinal irradiation range which are occupied by a guide board according to the transverse irradiation range and the longitudinal irradiation range which are occupied by the guide board, and the lamp bead controller controls and lights all the high-beam LED lamp beads in the set. According to the automatic guide board lighting system based on the geometrical multi-beam LED lamp, the position and the distance of the guide board are automatically identified on the premise that low-beam lamp driving cannot affect meeting, several high-beam lamp beads of which the light beams face the guide board are lighted (the other high-beam lamp beads keep a turn-off state, and meeting cannot be affected), and a driver can conveniently and clearly read important information on the guide board.
Description
Technical field
The present invention relates to automotive lighting field, particularly relate to a kind of guideboard based on geometry multiple beam LED and automatically shine
Bright system.
Background technology
Car light is the important component part of automobile, it can be that automobile is bad at light, haze weather or night etc. condition
Illumination is provided during lower traveling.Compared with dipped headlights, the light ray parallel injection of high beam, light is concentrated and brightness is relatively big, Ke Yizhao
To the highest farther object, the sight line for nighttime driving person is very helpful.But abuse the phenomenon phase of high beam at present
When seriously, the time of mistake uses high beam not only will not improve traffic safety, can give on the contrary to sending a car, pedestrian causes in short-term
Between blinding, largely increase the occurrence probability of peril.
For solving above-mentioned technical problem, current a lot of high-end automobiles have started to configure self adaptation long-and-short distant light, and automobile is adaptive
Answering distance-light illuminator is the vehicle utilizing the photographic head at vehicle mirrors position to detect traveling ahead, investigative range up to
400 meters.If be detected that send a car in opposite, dipped headlights will be automatically switched to, so guaranteeing the same of the clear visual field of driver
Time, also do not interfere with to the traveling sent a car, distance light can be automatically switched back into again when system detects when front does not has a vehicle.Drive
Member is no longer needed for oneself frequently switching distance-light and goes to avoid to dazzling.
But traditional self adaptation long-and-short distant light handoff technique is only to switch between dipped beam and distance light, at meeting
Time can be automatically switched off high beam because dipped headlights irradiate the most relatively low and limited brightness, be difficult to see roadside guideboard clearly, easily miss
Speed limit, show the way, the important driving instruction such as warning, there is huge potential safety hazard.In actual traffic participation process, driver meets
To manual unlocking high beam usual during guideboard to read guideboard information, though solving the problem illuminating guideboard, but also can be the most right
Opposed vehicle causes dazzling.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of guideboard based on geometry multiple beam LED
Automatic illuminating system, on the premise of not affecting meeting keeping dipped headlights to travel, automatically identifies guideboard position and distance, puts light
Several distance light lamp bead of Shu Chaoxiang guideboard, other distance light lamp bead remains off, it is simple to driver clearly reads on guideboard
Important information.
It is an object of the invention to be achieved through the following technical solutions: guideboard based on geometry multiple beam LED is automatic

Being connected, the outfan of lamp bead controller is connected with each controlled distance light LED lamp bead；
Described photographic head is used for Real-time Collection vehicle front image；
Described guideboard positioning unit goes out position and the distance of guideboard, and root for the image recognition collected according to photographic head
Position and distance according to guideboard determine horizontal range of exposures shared by guideboard and longitudinal range of exposures；
The memorizer of described lamp bead controller stores every distance light LED lamp bead independent range of exposures K in the horizontalm,
Independent range of exposures K in longitudinal directionn；Lamp bead controller, according to range of exposures horizontal shared by guideboard and longitudinal range of exposures, selects
Go out the set that range of exposures can cover the distance light LED lamp bead of horizontal range of exposures shared by guideboard and longitudinal range of exposures just,
Lamp bead controller controls to light all distance light LED lamp bead in foregoing assemblage.
Described photographic head is arranged at the center of left headlight and right headlight.
The process of guideboard automatic illuminating is as follows:
S1: image acquisition: in vehicle travel process, a certain moment, camera collection vehicle front image；
S2: guideboard positions: the image recognition collected according to photographic head goes out position and the distance of guideboard, and according to the position of guideboard
Put and distance determines horizontal range of exposures shared by guideboard and longitudinal range of exposures；
S3: light lamp bead: lamp bead controller, according to range of exposures horizontal shared by guideboard and longitudinal range of exposures, selects irradiation model
Enclosing the set of the distance light LED lamp bead that just can cover horizontal range of exposures shared by guideboard and longitudinal range of exposures, lamp bead controls
Device controls to light all distance light LED lamp bead in foregoing assemblage；
S4: repeat step S1-S3, until by this guideboard.
The invention has the beneficial effects as follows:
1) on the premise of keeping dipped headlights to travel not affecting meeting, automatically identify guideboard position and distance, light light beam towards
Several the distance light lamp bead (other distance light lamp bead remains off, and does not interferes with meeting) of guideboard, it is simple to driver clearly reads
Read the important information on guideboard.
2) using the distance light LED lamp bead of geometry multiple beam matrix arrangement, lighting and extinguishing of every lamp bead all can accurately be controlled
System, it is achieved that exact figureization controls, controls to provide the foundation for the selective driving beam in feasible region.
