Further, the MCU of headlamp control module receives the occupant position information from radio-frequency signal processing module, and
After the location information is parsed and handled, driven by the control command that LED is lighted in the transmission of UART bus to left/right LED
Chip, while being sent by LIN bus and adjusting the control command of motor position along the vertical and horizontal directions to left motor driven core
Piece or right motor drive ic, to irradiate to form a speck on car owner underfooting side ground always.
The utility model has the advantages that
1. according to the technical solution of the present invention, when car owner carry car key when in 1-10 meters of ranges of vehicle front,
Greeting lamp function is activated, and can form a speck in car owner foot, and follow the movement of car owner and move；When car owner is close to vehicle
When distance is less than 1 meter, greeting lamp function is closed.
2. technical solution of the present invention has more technology sense compared with traditional greeting lamp, increase between " people " and " vehicle "
Interactive function is further brought to car owner while reaching hospitality atmosphere to the feeling of car owner's a kind of " being gazed at by love vehicle "
More honorable senses.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes a kind of welcome's lamp control system, as shown in Figure 1, it includes radio-frequency signal processing module 1, preceding photograph
Lamp control module 2 and execution unit 3, headlamp control module 2 include MCU 21, left motor drive ic 22, right motor driven
Chip 23, left/right LED drive chip 24, CAN transceiver 25, LIN transceiver 26；Execution unit 3 includes two groups of motor verticals 31
And horizontal motor 32 and more particle LED lamp beads 33；Radio-frequency signal processing module 1 is connected with MCU 21 by CAN transceiver 25；
MCU 21 is connected with left motor drive ic 22 and right motor drive ic 23 by LIN transceiver 26；Left motor drive ic
22 with one group of motor vertical 31 and horizontal motor 32 by being electrically connected；Right motor drive ic 23 and another group of motor vertical 31 and
Horizontal motor 32 is by being electrically connected；MCU 21 is connected with left/right LED drive chip 24 by UART bus；Left/right LED driving
Chip 24 is with more particle LED lamp beads 33 by being electrically connected.
In the present embodiment, radio-frequency signal processing module 1 uses the BGA6130 core of the Mantra RF series of NXP company
Piece.KEA128 family chip of the MCU 21 using NXP company, model S9KEA128P80M48SF0.CAN transceiver 25 uses
TJA1040 model.LIN transceiver 26 uses TJA1021 model.Left/right LED drive chip 24 uses the model of TI company
The left/right LED drive chip of TPS92661-Q1.Left motor drive ic 22 and right motor drive ic 23 are all made of ST company
L9942 motor drive ic.
The control method of the present embodiment is as follows:
Firstly, coming into the recognizable fan-shaped region of vehicle front when car owner carries automobile intelligent key 4, work as radiofrequency signal
After processing module 1 recognizes the key to match, then an activation signal (or enable signal) is sent by CAN bus, when
After the MCU21 of headlamp control module 2 receives this signal, greeting lamp function is just activated, LED headlamp point is intuitively shown as
Bright and formation follows the hot spot of car owner.Meanwhile radio-frequency signal processing module 1 is by the i.e. car owner's in the position of the Intelligent key recognized
Location information, is sent to the MCU21 of headlamp control module 2, and the MCU 21 of headlamp control module 2 carries out the location information
After parsing and processing, 24 lightening LED lamp pearl 33 of left/right LED drive chip is controlled, irradiates to form one on car owner underfooting side ground
Speck, while controlling the position of left motor drive ic 22 or right motor drive ic 23 adjusting motor vertical 31 and horizontal motor 33
It sets, follows the movement of car owner always to adjust speck and move.
Specifically, when in the recognizable fan-shaped region that car owner enters vehicle front (radius be 10 meters, angle be 20 °-
160 °), headlamp control module 2 can judge in real time it is the a-quadrant in Fig. 2 or B area according to the location information of car owner,
If it is determined that car owner in a-quadrant, then forms hot spot using the car headlamp of a-quadrant side., whereas if judging car owner in B
Region then forms hot spot using the car headlamp of B area side, this is the process of a real-time judge and control.That is, working as vehicle
Principal and subordinate a-quadrant enters into B area, or enters into a-quadrant from B area, headlamp control module 2 all will according to car owner position come
Switching right and left lamp and control headlamp form hot spot.As shown in Fig. 2, T1 moment car owner appears in the position #1 of a-quadrant, T2 moment
Car owner walks about to the position #2 of a-quadrant, and vehicle left headlamp works and adjusts motor position in real time in the process, always in car owner's foot
Lower ground forms hot spot.When T3 moment car owner walks about to the position #3 of B area, vehicle shines before being switched to the right side from left headlamp
Lamp, i.e. left headlamp stop working, and right headlamp is started to work.Finally, when user close to vehicle location less than 1 meter when, then vehicle
" welcome " movement terminates.
Limiting the scope of the invention, those skilled in the art should understand that, in technical solution 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 of the invention
Within protection scope.
