Description
Technical field
The utility model is related to automobile lamp control technology field, more particularly to a kind of automobile LED tail lamp brilliance control system
System.
Background technology
The output of taillight signal designation is driver in a daily driving vehicle frequency of use function very high, especially
It is that in the case of night situation or environment be not good, taillight signal designation is played in front of the vehicles or pedestrians reminded below car
, play the purpose for preventing rear-end collision from occurring.
Simple car model LED taillight technologies are exactly to receive position lamp switch by BCM car body control modules at present
Signal, this signal is sent to BCM car body control modules by automobile combined switch by LIN buses, and BCM car body control modules are direct
Drive output LED taillights.No matter in which kind of environment, the output of LED taillights is held in certain brightness, can not adjust automatically
Section, can only be maintained at certain brightness.This technology is travelled, if front truck when driving a vehicle at night particularly in urban traffic
LED taillights are too bright, the situation that rear car driver's outlet can be allowed not see, and the eyes that dazzling feux rouges shines are difficult to receive, and especially exist
It is more serious when traffic congestion or vehicle low running speed.
Sometimes in overcast and rainy high speed traveling, again not enough, this is to be accomplished by improving brightness automatically allowing to LED taillight brightness
Rear car discovery early oneself.
The content of the invention
The technical problems to be solved in the utility model, is to provide a kind of automobile LED tail lamp brightness control system, can be with root
According to speed, environmental demand adjustment LED taillight brightness, traffic safety is improve.
What the utility model was realized in：A kind of automobile LED tail lamp brightness control system, including left side LED taillight, the right side
Side LED taillight, BCM car body control modules, automobile combined switch COLUMN ECU, automobile rainfall sensor and anti-lock are stopped
Car system ABS；The BCM car body control modules include MCU and LED lamp control chip；The automobile combined switch COLUMN
ECU and automobile rainfall sensor are connected by LIN buses with MCU, the anti-lock braking system ABS by CAN with
MCU is connected, and the MCU is connected with the LED lamp control chip, the LED lamp control chip respectively with the left side LED taillights
Connected with right side LED taillights.
Further, the LED lamp control chip is DMX512 control chips or SDMX5124 control chips.
The utility model has the advantage of：The utility model can be according to current vehicle by MCU and LED lamp control chip
Speed, weather, environment adjustment LED taillight brightness, avoid brightness too high and influence the driving of rear car as far as possible, in high speed traveling or
Need to improve brightness again during rainy day low visibility to allow rear car discovery early oneself.
Brief description of the drawings
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Refer to shown in Fig. 1, a kind of automobile LED tail lamp brightness control system, including left side LED taillights 1, right side LED tails
Lamp 2, BCM car body control modules 3, automobile combined switch COLUMN ECU4, automobile rainfall sensor 5 and anti-lock brake system
System ABS6；The BCM car body control modules 3 include MCU31 and LED lamp control chip 32；The automobile combined switch COLUMN
ECU4 and automobile rainfall sensor 5 are connected by LIN buses with MCU31, and the anti-lock braking system ABS6 is total by CAN
Line is connected with MCU31, and the MCU31 is connected with the LED lamp control chip 32, the LED lamp control chip 32 respectively with institute
State left side LED taillights 1 and right side LED taillight 2 is connected.
In addition, in actual applications, the LED lamp control chip is DMX512 control chips or SDMX5124 control cores
Piece.
In the utility model, the MCU in BCM car body control modules 3 receives automobile combined switch COLUMN ECU4 and sends
Position lamp switching signal, automobile rainfall sensor 5RAINLIGHT SENSOR send rainfall high low signal, anti-lock brake
The GES that system ABS6 sends, MCU31 is adjusted after combinational logic judges these signals according to LED lamp control chip 32
Whole output LED luminance.
Design BCM car body control modules 3 by this just can adjust LED taillight brightness according to current vehicle speed, weather environment.
Including following several situations.
One：When night low speed is driven a vehicle, LED car lamp avoids the need for so bright, and BCM car body control modules 3 are according to automobile group
The position lamp switching signal of combination switch COLUMN ECU4 and the GES of anti-lock braking system ABS turn down the bright of LED taillights
Degree, avoids brightness too high and influences the driving of rear car as far as possible.
Two：In high speed traveling, it is necessary to improve taillight brightness to allow rear car to find oneself early, BCM car body control modules 3
The GES of position lamp switching signal and anti-lock braking system ABS according to automobile combined switch COLUMN ECU4 is heightened
The brightness of LED taillights.
Three：When driving a vehicle the rainy day, because weather reason causes the visual field fuzzy, it is necessary to improve taillight brightness to allow rear car early
It was found that oneself, BCM car body control modules 3 are stopped according to the position lamp switching signal of automobile combined switch COLUMN ECU4, anti-lock
The GES of car system ABS, the rainfall signal of automobile rainfall sensor heighten the brightness of LED taillights.
Although the foregoing describing specific embodiment of the present utility model, those familiar with the art should
Work as understanding, the specific embodiment described by us is merely exemplary, rather than for the limit to scope of the present utility model
Fixed, those of ordinary skill in the art should in the equivalent modification and change made according to spirit of the present utility model
Cover in scope of the claimed protection of the present utility model.
