Referring to Fig. 2, a kind of schematic flow sheet of the traffic accident prevention method provided for present pre-ferred embodiments, institute
The automobile 100 of method as shown in Figure 1 is stated to perform.It should be noted that method provided in an embodiment of the present invention is not with Fig. 2 and following
Described particular order is limitation.The idiographic flow of methods described is as follows：
Step S210, obtain the direction information of automobile 100.
Specifically, in the present embodiment, when the automobile 100 turns to, institute can be obtained by the detection unit 150
The direction information of automobile 100 is stated, wherein, the direction information can specifically include steering direction and steering angle, for example, can be with
Detect that the 100 positive right direction of automobile turns to 30 degree.
Step S220, it is poor that the lubrication groove formed when the automobile 100 turns to is calculated according to the direction information.
In the present embodiment, because automobile 100 is when turning, trailing wheel is not the track traveling along front-wheel, can be produced partially
Difference, the deviation for formation of turning is " wheel is poor ", and vehicle body is longer, and " wheel is poor " of formation is bigger, and the scope of lubrication groove difference also can and then expand
Greatly.The vehicle body of heavy construction car is all long, and after especially headstock turns round, also very long vehicle body does not turn over, easily
Form " vision dead zone " of oversize vehicle driver.After non-motor vehicle or pedestrian step into " vision dead zone " scope of lubrication groove, produce
Dangerous increase.Due to being close to vehicle body, rear when being turned round is dragged in in-car, causes traffic accident.
In consideration of it, current embodiment require that poor, the poor (Difference of lubrication groove that calculates the lubrication groove that is formed when turning to of automobile 100
Of Radius Between Inner Wheels) be in Ackermann steer angle nose-wheel turn radius and inner rear wheel radius of turn it
Difference.Then it is the difference of the inner rear wheel radius of turn of the interior front-wheel and trailer of tractor for tractor.
Specifically, referring to Fig. 3, as a kind of embodiment, the step S220 can include following sub-step：
Sub-step S221, the min. turning radius when automobile 100 turns to is calculated according to the direction information.
In the present embodiment, for automobile 100 when being turned, the movement locus of front-wheel is approximately round, therefore can be according to vapour
The steering angle and steering direction of car 100 calculate the min. turning radius when automobile 100 turns to.
Sub-step S222, according to the trailing wheel of the min. turning radius, the wheelbase of the automobile 100 and the automobile 100
First distance in the center of circle and the trailing wheel of the automobile 100 corresponding to front-wheel to min. turning radius away from the calculating automobile 100
To the second distance in the center of circle corresponding to min. turning radius.
Specifically, in the present embodiment, lubrication groove difference function model, the lubrication groove difference function are stored with the automobile 100
Include the wheelbase L of automobile 100 and the rear tread d of automobile 100 in model, wherein, the wheelbase can be the front-wheel of automobile 100
The distance between trailing wheel.Assuming that min. turning radius is r, the first distance of the front-wheel of automobile 100 to center of circle o points is R1, automobile
The second distance of 100 trailing wheels to center of circle o points is R2, then r, L, d, R1、R2Following relation can be met：
(R2+d)2+L2=r2
R2 2+L2=R2 1
According to above-mentioned calculating, it can be deduced that the first distance R1For：
The second distance R2For：
Sub-step S223, calculate what is formed when the automobile 100 turns to according to first distance and the second distance
Lubrication groove is poor.
In the present embodiment, according to above-mentioned calculating, the calculation formula of the lubrication groove difference R is：
Referring to Fig. 2, step S230, judge whether to need to detect target area according to the lubrication groove difference.
In the present embodiment, the target area surrounds for the front wheel track and rear wheel tracks of the steering direction of automobile 100
Region.Specifically, first, it is determined that whether the lubrication groove difference is more than predetermined threshold value：If being more than, judgement is needed to target area
Detected.If being not more than, judgement need not detect to target area.
If so, then performing step S231, the target area is detected, and is detecting the target area presence
When having destination object, control the baffle plate to land, the destination object is removed from the target area, to avoid occurring
Traffic accident.
In the present embodiment, it can be arrived by ultrasonic sensor to the target area emission detection ripple, the probing wave
Up to back wave corresponding to the destination object back reflection of the target area, then receive what is reflected via the target area
Back wave, signal transacting is carried out to the back wave, the target area is judged with the presence or absence of there is destination object, detecting
When stating the target area and there are destination object, the baffle plate is controlled to land, by the destination object from the target area
Removed in domain, to avoid that traffic accident occurs.
Further, if it is not, need not be detected to the target area, then step S232 is performed, described in judgement
Whether automobile 100 is in turn condition.
If so, then performing step S232a, continue to detect the target area.
If it is not, then performing step S232b, stop detecting the target area.
Based on above-mentioned design, direction information during by being turned to according to automobile 100 calculates what is formed when automobile 100 turns to
Lubrication groove is poor, target area is detected when detecting that lubrication groove difference is more than predetermined threshold value, and detecting the target area
When there are destination object, controlling baffle plate landing, the destination object is removed from the target area, can be by accident
During the extent of injury to caused by traffic participant be preferably minimized, reduce accident occur property loss.
Further, it is described referring to Fig. 5, present pre-ferred embodiments also provide a kind of traffic accident prevention device 200
Device includes：
