Please refer to Fig. 2-Fig. 4, by vehicle blind zone monitoring early-warning system 100 be applied to an automobile 200 for the present invention into
Row explanation.Automobile 200 includes vehicle body 210, front-wheel 220 and trailing wheel 230.The front-wheel 220 and trailing wheel 230 are located at vehicle body 210
The same side.Obstacle detection device 10 is installed on vehicle body 210 and neighbouring trailing wheel 230 is set.For example, obstacle detection device 10 is pacified
Loaded on 230 top of trailing wheel.In the present embodiment, obstacle detection device 10 is an infrared curtain detector, including a detection
Region S.As in Figure 2-4, search coverage S is a belt-like zone, and the detection range of obstacle detection device 10 is the detecting area
Region between domain S and vehicle body 210.By the detection direction for setting the obstacle detection device 10, you can make the detection range extremely
It is few include due to when automobile 200 is turned due to " lubrication groove is poor " exists and is formed the vision dead zone in lubrication groove difference region, i.e. driver.
When human body, automobile or other barriers enter the detection range into or through search coverage S, obstacle detection device 10 is then
Export the obstacle detection signal.It is appreciated that the obstacle of the detection range is not entered when automobile 200 has just started and turned
Object, moving and being likely to travel through search coverage S and enter detection range during turning with automobile 200, the i.e. inspection
Surveying range can accordingly move with the movement of automobile 200.
Since the angle of turn of automobile 200 is bigger, the lubrication groove difference region between front-wheel 220 and trailing wheel 230, i.e. vision is blind
The range in area is bigger, and therefore, in the present embodiment, the angle of turn of automobile 200 is bigger, then the detection of obstacle detection device 10
Range is bigger；Conversely, the angle of turn of automobile 200 is smaller, then the detection range of obstacle detection device 10 is smaller.
Referring back to Fig. 1, specifically, in the present embodiment, adjustment module 40 is used for the angle of turn according to automobile 200
Angle between the detection direction of insufficiency of accommodation object detector 10 and vehicle body 210, that is, the angle between search coverage S and vehicle body 210
Degree.Adjustment module 40 includes the steering angle sensor 41, drive signal processor 42 and the motor 43 that are electrically connected successively.Turn
It is used to detect the angle of turn of the angle of turn, i.e. front-wheel 220 of automobile 200 to angular transducer 41, and according to angle of turn
The corresponding detection signal that turns to of size output is to drive signal processor 42.Drive signal processor 42 is used to be examined according to the steering
The corresponding control signal of signal output is surveyed to motor 43, to control the angle of the rotation of motor 43.Motor 43 is connected to barrier
Detector 10 for obstacle detection device 10 being driven to be moved to corresponding position according to the drive signal, is hindered with corresponding adjust
Hinder the angle between the detection direction of object detector 10 and vehicle body 210, that is, the detection range of insufficiency of accommodation object detector 10.
For example, Fig. 2-4 respectively illustrates vehicle body 210 of the front-wheel 220 of present embodiment under three different angle of turn
With the schematic diagram of search coverage S.When angle X1-X3 represents that the angle of turn of front-wheel 220 is sequentially increased respectively, vehicle body 210 is with visiting
Survey the angle between the S of region；When detection range M1-M3 represents that the angle of turn of front-wheel 220 is sequentially increased respectively, obstacle detection
The detection range of device 10；When lubrication groove difference region N1-N3 represents that the angle of turn of front-wheel 220 is sequentially increased respectively, front-wheel 220 is with after
Lubrication groove difference region between wheel 230.It can be seen that by Fig. 2-4, as the angle of turn of front-wheel 220 is sequentially increased, vehicle body 210 is with visiting
The angle X1-X3 surveyed between the S of region is sequentially increased, and the lubrication groove difference region between front-wheel 220 and trailing wheel 230 is sequentially increased, simultaneously
The detection range M1-M3 of obstacle detection device 10 is also sequentially increased.
It is appreciated that when steering angle sensor 41 senses automobile 200 without turning or angle of turn very little,
That is, when 200 normally travel of automobile is not turned, at this point, the detection range of obstacle detection device 10 is smaller, therefore without barrier into
Enter in the detection range, therefore alarm module 30 will not alarm, the interference to driver will not be caused.
The vehicle blind zone monitoring early-warning system 100 detector 10 that breaks the barriers has been detected whether in automobile turning
Barrier barriers to entry object detector, processing module 20 then when there is barrier to enter the detection zone, report by driving alarm module 30
It is alert.Even if in this way, when automobile 200 is turned since the presence of lubrication groove difference forms vision dead zone, into the barrier in vision dead zone
Hinder object that can also be detected simultaneously alerting drivers, effectively increase the safety in driving conditions.Meanwhile pass through adjustment module
The angle of turn of the 40 detection automobiles, and the obstacle detection device 10 is adjusted according to the angle of turn of the automobile 200
