Abstract
The present invention discloses a kind of vehicle and drives into before tunnel the control system for opening headlight, belongs to car light control field.It includes front camera, signal processor and car light controller, and signal processor is connected with front camera and car light controller respectively, and signal processor is powered by 12V vehicle power supplies.The present invention acquires front road conditions image by front camera, then carries out image procossing by signal processor, when being tunnel in front of identification, can drive into tunnel premise front opening headlight in vehicle, improve the safety of driving.
Description
Technical field
The invention belongs to car light control field, especially a kind of vehicle drives into the control system of unlatching headlight before tunnel.
Background technology
This road conditions in tunnel are frequently encountered in some cities or mountain area, internal and external environment luminous intensity differs greatly when tunnel
When, driver will appear the dark adaptation phenomenon of certain time when driving to drive into tunnel, this is very dangerous a kind of situation,
There are larger security risks.
And in the prior art, the automatic opening function of automobile front is generally realized using light sensitive device, but light sensation
The shortcomings that device, which is the dark surrounds that only automobile enters in tunnel, can just open headlight, can not accomplish to open in advance before entering tunnel
Car headlamp is opened, road lighting is provided.
Invention content
In order to solve the above technical problems, the present invention, which provides a kind of vehicle, drives into before tunnel the control system for opening headlight, lead to
Front camera acquisition front road conditions image is crossed, then image procossing is carried out by signal processor, it, can be when identification front is tunnel
Vehicle drives into tunnel premise front opening headlight, improves the safety of driving.
To achieve the above object, the present invention uses following technical proposals：
A kind of vehicle drives into the control system of unlatching headlight before tunnel, it includes front camera, signal processor and vehicle
Lamp controller, signal processor are connected with front camera and car light controller respectively, and signal processor is supplied by 12V vehicle power supplies
Electricity；
Front camera acquires front road conditions image in real time, and is sent to message handler, before signal processor receives
After Fang Lukuang images, image is handled and judge front whether be tunnel, by front be tunnel judging result to control
The form of order is sent to car light controller, and car light controller opens headlight according to control command.
Further, the ambient light intensity in front camera perception tunnel, and it is sent to signal processor, signal processing
Device is by the ambient light intensity received compared with predetermined threshold value, and the result by ambient light intensity higher than predetermined threshold value is with control command
Form be sent to car light controller, car light controller closes headlight according to control command.
Further, front camera is connected with signal processor by video line；
Car light controller is connected with signal processor by CAN bus.
Further, front camera is installed on the inside of front windshield.
Further, front camera is installed on inside rear-view mirror rear.
Advantageous effect：
1. traffic information and handled by the present invention in that acquiring front in real time with front camera, when recognizing front road conditions
Can tunnel when, unlocking vehicle headlamp in advance.
2. the present invention substitutes light sensitive device by front camera, the acquisition to ambient light intensity in tunnel is realized, according to
Ambient light intensity is to determine whether need to close or continue on headlight.
3. the present invention, instead of light sensitive device, radar and vehicle mounted guidance etc., is greatly reduced using front camera
Hardware cost.
Description of the drawings
Fig. 1 is that the vehicle of one embodiment of the invention drives into the control system Organization Chart of unlatching headlight before tunnel；
In figure：1- front cameras, 2- signal processors, 3- car light controllers, 12V vehicle power supplies.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes to open the control system of headlight before a kind of vehicle drives into tunnel, as shown in Figure 1, it includes preposition
Camera 1, signal processor 2 and car light controller 3, front camera 1 are connected with signal processor 2 by video line, car light
Controller 3 is connected with signal processor 2 by CAN bus, and signal processor 2 is powered by 12V vehicle power supplies 4, front camera 1
It is installed on the inside of front windshield, it is preferred that front camera 1 is installed on inside rear-view mirror rear.
The control method of the present embodiment is：Road conditions image in front of the acquisition in real time of front camera 1, and it is sent to information processing
Device 2 after signal processor 2 receives front road conditions image, handles image and judges whether front is tunnel, by front
Car light controller 3 is sent in the form of control command for the judging result in tunnel, car light controller 3 is according to control command in vehicle
Headlight is opened before driving into tunnel, improves the safety of driving.After vehicle enters tunnel, front camera 1 perceives tunnel
Interior ambient light intensity, and be sent to signal processor 2, signal processor 2 is by the ambient light intensity received and predetermined threshold value
Compare, ambient light intensity is sent to car light controller 3, car light control higher than the result of predetermined threshold value in the form of control command
Device 3 closes headlight according to control command.Conversely, then keeping headlight to continue to light, until ambient light intensity is higher than predetermined threshold value.
Limiting the scope of the invention, those skilled in the art should understand that, in technical scheme of the present invention
On the basis of, the various modifications or variations that can be made by those skilled in the art with little creative work still the present invention's
Within protection domain.
