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 anti-warning lamp control system that knocks into the back, as shown in Figure 1, it includes Signal acquiring and processing mould
Block 1, motor driving and execution module 2 and imaging device 3, Signal acquiring and processing module 1 include camera 11, BCM modules 12
With signal processor 13, camera 11 is installed on automotive rear windshields or is integrated in inside back light, camera 11 and letter
Number processor 13 is connected by video line, and BCM modules 12 are connected with signal processor 13 by CAN bus；
It includes motor drive ic 21, horizontal motor 22 and motor vertical 23, motor driving that motor, which drives with execution module 2,
Chip 21 is connected with horizontal motor 22 and motor vertical 23 respectively；Motor drive ic 21 is total by CAN with signal processor 13
Line is connected；
Imaging device 3 includes DMD controllers 31 and DLP projection arrangements 32, and DMD controllers 31 pass through with signal processor 13
Spi bus is connected, and DMD controllers 31 are connected with DLP projection arrangements 32；
The light-emitting window of imaging device 3 is installed on automobile rear.Preferably, the light-emitting window of imaging device 3 is installed on licence plate
It sets (near license plate lamp) in orientation.
Camera 11 acquires the real-time image information of front vehicle and sends signal processor 13 to, and signal processor 13 is logical
It crosses conventional image-recognizing method and detects that the position of front vehicle and spacing information, synchronous signal processor 13 pass through BCM moulds
Block 12 obtains body information, after comprehensive descision, sends control command to motor drive ic 21 and DMD controllers 31 respectively,
Motor drive ic 21 receives the control command of signal processor 13, and drives horizontal motor 22 right in real time with motor vertical 23
The light-emitting window of imaging device 3 carries out the adjustment of horizontal position and upright position, and DMD controllers 31 receive signal processor 13
Control command, and control dmd chip and form different projection pattern (anti-knock into the back warning mark or word), DLP projection arrangements
The projection pattern that DMD controllers 31 are formed is projected ground by 32.
The control method of the present embodiment is：
(1) signal processor 13 obtains this vehicle speed information by BCM modules 12, sets two different operating modes, i.e.,
Non-high velocity mode and high-speed mode；When speed is less than 80km/h and keeps 30s, then signal processor 13 judges to be currently non-high-speed
Pattern；
(2) as shown in Fig. 2, when speed is more than 100km/h and keeps 30s, then signal processor 13 judges currently for high speed
Pattern, then early warning distance is 200 meters, i.e., imaging device 3 is switched on when there is vehicle within the scope of 200 meters of rear, in front vehicle
Road surface ahead on project warning mark.If conversely, not projecting warning mark without vehicle in 200 meters of rear.Meanwhile root
According to the real time position of vehicle, signal processor 13 controls motor drive ic 21 to drive horizontal motor 22 real with motor vertical 23
When the adjustment of horizontal position and upright position is carried out to the light-emitting window of imaging device 3, i.e., the position for projecting image is carried out real-time
Adjustment, remains warning mark on the road surface ahead of front vehicle.
(3) as shown in figure 3, when vehicle is in the case of bend, this system can will be warned according to the position of front vehicle
Mark accurately projects on the road surface ahead of front vehicle, and even when turning round, front vehicle disappears in 11 visual field of camera
In range, then signal processor 13 judges rear without vehicle, i.e., without the risk to knock into the back, at this point, closing imaging device 3, does not project
Alert flag, until camera 11 captures vehicle of the rear appearance with vehicle again.
(4) as shown in figure 4, in the case that more vehicles occurs in rear, this system can be before the vehicle for the risk that most knocks into the back
Alert flag is projected on square road surface.
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.
