Description
Technical field
The invention belongs to road vehicle component field, especially a kind of dynamic daytime running lamps system.
Background technology
With the development of LED technology, compared with halogen lamp, LED has energy conservation and environmental protection, advantage with long service life.From upper
The eighties in century LED technology be applied to high-mount brake lamp since, more and more LED are applied to taillight, and steering indicating light drives a vehicle in the daytime
Lamp, dipped headlight, high beam etc..The development trend of LED has also been confirmed in the appearance of some full LED vehicles in recent years.Wherein, it goes in the daytime
Car light has become rules and regulations lamps and lanterns in Europe.On the one hand, although it is domestic for daytime running lamps without rules and regulations,
Daytime running lamps have become a bright spot of vehicle, and more and more main engine plants are using daytime running lamps as the mark of new model
Match；On the other hand, as the bus communicated with vehicle, LIN buses are highly suitable to be applied for on-vehicle lamp control because of low cost
Device.
Invention content
To solve the single defect of existing daytime running lamps system function, the present invention provides a kind of dynamic daytime running lamps
System.
To achieve the above object, the present invention uses following technical proposals：
A kind of dynamic daytime running lamps system, it includes master controller, drive module, light-adjusting module, LED lamp panel, electricity
Source voltage stabilizing chip and LIN transceivers, master controller are provided stable voltage by power supply voltage stabilizing chip, and master controller is received by LIN
Hair device is communicated with car body controller, and master controller is communicated by UART buses with light-adjusting module, and master controller passes through
Light-adjusting module controls the on and off of LED lamp panel；
LED lamp panel provides constant current output by drive module, and each LED in LED lamp panel individually carries out PWM light modulations,
And it is lighted successively by certain sequential.
Further, light-adjusting module is connected in parallel on LED lamp panel both ends, and the on and off by being bypassed to LED lamp panel come
PWM light modulations are carried out to LED.
Further, master controller is connected by LIN buses with car body controller, and master controller is according to the reports of LIN buses
Literary information parses various operating modes.
Advantageous effect：
1. each LED can individually realize that PWM is dimmed in the LED lamp panel of the present invention；The dynamic of continuous-flow type is lighted
LED so that visual effect is more prominent, is effectively improved the driving experience of client.
2. the present invention can dim reduce brightness by PWM, position lamp function is realized.
3. the present invention is connected by LIN buses with car body controller, the fault diagnosis to daytime running lamps may be implemented, separately
Outside, by parsing the message information of LIN buses, more functions can be expanded out.
Description of the drawings
Fig. 1 is the system module figure of one embodiment of the invention；
In figure：1- master controllers, 2- drive modules, 3- light-adjusting modules, 4-LED lamp plates, 5- power supply voltage stabilizing chips, 6-LIN
Transceiver.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes a kind of dynamic daytime running lamps system, as shown in Figure 1, it includes master controller 1, driving mould
Block 2, light-adjusting module 3, LED lamp panel 4, power supply voltage stabilizing chip 5 and LIN transceivers 6, master controller 1 are provided by power supply voltage stabilizing chip 5
Stable voltage, master controller 1 receive the message information of LIN buses by LIN transceivers 6, and parse various operating modes,
Master controller 1 is communicated by UART buses and light-adjusting module 3, and light-adjusting module 3 is connected in parallel on 4 both ends of LED lamp panel, plays LED
The effect of 4 by-pass switch of lamp plate, light-adjusting module 3 are controlled by master controller 1, by and off that LED lamp panel 4 is bypassed come
PWM light modulations are carried out to LED；
LED lamp panel 4 provides constant current output by drive module 2, and LED lamp panel 4 has 12 LED, each in LED lamp panel 4
LED can individually carry out PWM light modulations；
In daytime running lamps opening process, LED is lighted successively according to certain sequential, realizes dynamic effect.
In dynamic daytime running lamps opening process, specific implementation mode is：It can light LED1 first, after 20ms, close
It closes LED1, after 20ms, is then turned on LED2, after 20ms, close LED2.Each LED is lighted successively, after being illuminated to LED12, then it is past
It returns and is illuminated to LED1.The state of each LED can be tested in LED scanning processes.Again since LED1, be delayed 30ms, successively
LED2 is lighted, is lighted until all, dynamic process terminates.
The status information of daytime running lamps can be uploaded to by LIN buses in car body controller, and realization goes in the daytime to this
The fault diagnosis of car light.The use of LIN buses is also conducive to the expansion of follow-up function.By PWM dimming modes, make shining for LED
Brightness reduces, but not influences the photochromic of LED, to allow the daytime running lamps to be used as position lamp.
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.
