Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is explicitly described, it is clear that, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
For ease of the understanding to the embodiment of the present invention, being further explained explanation below in conjunction with accompanying drawing with specific embodiment, embodiment is not intended that the restriction to the embodiment of the present invention.
The traffic safety method for early warning that the embodiment of the present invention provides is described in detail below for Fig. 1, and please in combination with reference Fig. 2, subject of implementation is a comprehensive treatment equipment in embodiments of the present invention.As it is shown in figure 1, this embodiment specifically includes following steps 110-step 140:
Step 110, acquisition vehicle traveling lane information, driving vehicle width W1And real-time vehicle running information；
In the present embodiment, described lane information includes lane line width W, and described real-time vehicle running information includes the speed of time and driving vehicle.Wherein, lane line width W is single lane width.

Below incorporated by reference to consulting Fig. 2, in the present embodiment, complete once complete S type traveling for driving vehicle to illustrate.
The initial time of transformation period section, vehicle with uniform velocity in the road between travel, now, left and right body side is (W W from the correspondence distance from left and right lane line1)/2；From the t1 moment to the t2 moment, vehicle is turned right with speed S, and vehicle becomes larger from current lane left side distance, on the right of current lane, distance tapers into, in the t2 moment, the right lane line of vehicle pressure current lane, now vehicle is W-W from the distance of the left lane line of Current vehicle1, the distance from the right lane line is zero；Vehicle continues to turn left with speed S to travel to the t3 moment, in the t3 moment, vehicle has reached the maximum transversal deviation point that this complete curve shape travels, it is the process that vehicle returns back to original lane position from the t3 moment to the t5 moment, it is substantially from the t1 moment to the reverse process in t3 moment, does not repeat them here.This embodiment is to occur a S type curve driving to illustrate in transformation period section, obviously, if repeatedly maximum transversal deviation distance occurs in transformation period section, illustrate to occur in that repeatedly S type curve driving in this transformation period section, it is possible to judge whether fatigue driving etc. according to the frequency of S type curve driving.
Step 130, judge the driving behavior when a transformation period section terminates according to maximum transversal change distance, vehicle traveling lane information and driving vehicle width, and export described driving behavior result；
In the present embodiment, when maximum transversal changes distance 0 to (W-W1) between change time, then export the behavior analysis result of normal driving, i.e. think that vehicle is simply in a track, does slight oscillatory back and forth, belongs to normal driving.
When maximum transversal change distance is always close to W-W1During change, then export in current lane, do the driving behavior result swung by a relatively large margin, i.e. think that vehicle is still in a track, does back and forth and swings by a relatively large margin；If maximum transversal change distance occurs repeatedly keeping a period of time close to W-W in transformation period section1Situation of change, then the driving behavior exported for drive unskilled or fatigue driving；Otherwise driving behavior is normal traveling.
When maximum transversal changes distance at W-W1To W-W1Between+W ÷ 2 during change, then the driving behavior that discriminatory analysis goes out is that vehicle is crossed over to closing on track and the line of riding with the short time travels, and without the absent-minded of lane change or fatigue driving behavior.
When maximum transversal changes distance at W-W1+ W ÷ 2 to W-W1Between+W during change, the driving behavior then exported is that lane change is driven, namely, think that vehicle has passed over and close on track, complete lane change process, belong to the conscious lane change of driver and drive, if transformation period section is less than default threshold value, and occurrence number maximum transversal change distance in transformation period section, then the driving behavior exported is that continuous lane change is driven, and the driving behavior otherwise exported is normal lane change passing behavior.
Step 140, according to the driving behavior output early warning information judged, when the driving behavior judged is unsafe act, then output traffic safety early warning, or send thermoacoustic prime engine signal described driving vehicle is controlled.Described early warning for sending corresponding sound according to corresponding driving behavior or showing that corresponding image is pointed out, described in send thermoacoustic prime engine signal and be controlled described driving vehicle can being control vehicle with control information such as brakes to stop.
In the present embodiment, when driving behavior is for driving unskilled, fatigue driving, continuous lane change or when walking S type curve, output safety early warning or or send thermoacoustic prime engine signal described driving vehicle is controlled.
Therefore, by applying traffic safety method for early warning provided by the invention, the vehicle traveling lane information obtained, driving vehicle width and real-time vehicle running information are processed, to analyze the driving behavior in transformation period section, and judge whether the driving behavior in current transformation period section is safe driving behavior, when for unsafe driving behavior, then send traffic safety early warning, or send thermoacoustic prime engine signal described driving vehicle is controlled.Ensure that the safety of driver and vehicle, reduce vehicle owing to walking the probability that the unsafe driving behaviors such as S type curve, fatigue driving are caused danger.
