Detailed Description

For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.

Therefore, the method for detecting the potential safety hazard during the driving at the road curve can detect the potential safety hazard in real time according to the speed of the current vehicle and the distance between the current vehicle and the road curve, so that the potential safety hazard detection does not depend on the limiting conditions, the application scene of the scheme is expanded, and the method has the advantages of wide application.

Referring to fig. 1, the implementation process of the method for detecting the traffic safety hazard at the road curve is as follows:

and S101, acquiring the speed V1 of the current vehicle and the distance S1 of the current vehicle from the curve opening of the curve in real time.

The curved road may be divided into two sides by using the curved road as a central point as shown in fig. 2, and the curved road is divided into an a side and a B side as shown in fig. 3. And the current vehicle is located on the first side of the curve, which may be side a, as shown in fig. 4, or side B, as shown in fig. 5.

Various vehicles run on the curve in real time, and the wireless sensor is arranged at a position 50-80 meters away from the curve opening, and the wireless sensor is 1 meter away from the ground, so that the current vehicle is detected through the wireless sensor.

That is, wireless sensors are respectively provided at both sides of the curve from 50 meters to 80 meters, and the vehicle is detected by the wireless sensors at both sides, and if the vehicle is detected, the vehicle is the current vehicle.

The method provided by the embodiment can be used for carrying out targeted potential safety hazard detection on each vehicle detected by the wireless sensor, and personalized detection service for detecting thousands of vehicles is realized.

Also, since the wireless sensors detect that the vehicle is located on both sides of the curve, the wireless sensors are disposed on both sides a and B in fig. 3, and thus, if the wireless sensor on the side a detects the current vehicle, the first side on which the current vehicle is located is the side a, as shown in fig. 4. If the wireless sensor on side B detects the current vehicle, the first side on which the current vehicle is located is side B, as shown in FIG. 5.

The unit of V1 is km/h.

S102, acquiring the speed V2 of the coming vehicle and the distance S2 of the coming vehicle from the road junction in real time.

And the coming vehicle is positioned on the second side of the curve, and the driving direction of the coming vehicle is opposite to that of the current vehicle.

The second side is the other side of the first side, see fig. 3, if the first side is side a, then the second side is side B, i.e. the current vehicle is as shown in fig. 4, then the coming vehicle is as shown in fig. 6. If the first side is side B, then the second side is side a, i.e. the current vehicle is as shown in fig. 5, then the oncoming vehicle is as shown in fig. 7.

In addition, the unit of V2 is km/h.

It should be noted that, while various vehicles are traveling in the curve in real time, not all vehicles traveling in the other side of the curve are coming vehicles. Only the vehicle with the security threat to the current vehicle is the coming vehicle, so after S101 is executed, the coming vehicle is determined before S102 is executed, and the determination scheme for the coming vehicle is as follows:

s201, obtaining the current visibility V.

Where visibility is in meters.

This visibility can be obtained by the meteorological department.

Visibility has influenced driver's visible range, and visibility is lower, and driver's visible range is littleer, but the scheme that this embodiment provided does not receive visibility to influence, and the scheme through this embodiment can reduce driver's visible range and compensate, consequently, seeks the scope of coming a car according to the corresponding adjustment of visibility to as the visible impaired compensation of driver with the scheme that provides through this embodiment, provide more accurate potential safety hazard and detect, let the driver carry out early warning to the coming car before visible.

S202, acquiring the speed V3 when the wireless sensor firstly detects the current vehicle and the distance S3 between the current vehicle and the road junction when the wireless sensor firstly detects the current vehicle.

Wherein the unit of V3 is kilometer per hour.

S203, determining a detection distance S according to the V3, the S3 and the V.

Wherein the determination process of S is as follows:

computing

If V'>1, and V3 ≧ 30, then it is determined

If V' >1, and V3<30, then determine S-S3.

If V ≦ 1, S is determined to be S3+ S3 (1-V').

The detected distance S is related to the vehicle speed at which the current vehicle is found for the first time, in addition to the visibility V. If the current vehicle speed is found to be fast for the first time, the control capability of a driver to the vehicle is reduced, if the braking distance is increased, the possibility that the vehicle is dangerous when entering a curve is increased, the range of the vehicle is correspondingly adjusted to find the vehicle, the scheme provided by the embodiment is used as compensation for the reduction of the vehicle control capability of the driver to the vehicle speed, more accurate potential safety hazard detection is provided, and the driver can perform early warning processing on the vehicle outside the controllable distance.

And S204, determining a detection area according to S, wherein the detection area is a lane area in the second side opposite to the current vehicle driving direction, and the lane length in the lane area is S.

If the present vehicle is located on the a side as shown in fig. 4, the detection area is as shown in fig. 8. If the current vehicle is located on the B side as shown in fig. 5, the detection area is as shown in fig. 9.

And S205, determining the vehicles in the detection area as coming vehicles.

In addition, a plurality of coming vehicles can exist, and the scheme can calculate and respectively give an early warning for each coming vehicle.

S103, detecting potential safety hazards according to V1, V2, S1 and S2.

In particular, the amount of the solvent to be used,

(1) and if the V1 is more than or equal to 15, determining that the potential safety hazard is detected.

(2) And if the V2 is more than or equal to 15, determining that the potential safety hazard is detected.

(3) If V1<15 and V2<15, then

Determining a first time

Determining a second time

And detecting potential safety hazards according to T1, T2 and V.

Such as: if it is

It is determined that a potential safety hazard is detected. Otherwise, determining that the potential safety hazard is not detected.

In addition, after the potential safety hazard is detected, an alarm is given, such as sending V2, S2 and a motion trail diagram of an incoming vehicle to the current vehicle.

The motion trail diagrams of the V2 and the S2 and the coming vehicle can be displayed through a display screen beside a curve, can also be sent to a display screen in the current vehicle for displaying, can also be broadcasted through a sound playing device in the current vehicle, and the like.

In addition, the color of the trajectory in the motion trajectory graph is transformed based on the risk level, and for example, the RGB value at any point on the trajectory in the trajectory graph is: the G channel value is 0. The B channel value is 0. R channel value of

Since S1, S2 are varied in real time, the value of the R channel is changed based on the distance of the vehicle from the road junction.

The method and the system for detecting the potential safety hazard during driving at the road curve can detect the potential safety hazard in real time according to the speed of a current vehicle and an incoming vehicle and the distance between the current vehicle and the curve mouth, so that the potential safety hazard detection does not depend on a limiting condition, the application scene of a scheme is expanded, and the method and the system have the advantages of wide application.

In addition, the method provided by the embodiment can dynamically adjust the coming vehicle confirmation range according to the current vehicle speed and the current visibility, and realizes the accuracy and reasonableness of the coming vehicle confirmation.

In addition, whether the detection result of the potential safety hazard exists is based on the real-time transformation of the speed of the coming vehicle and the current vehicle and the distance between the coming vehicle and the current vehicle and the bend opening, so that the accurate detection of different current vehicle conditions and different coming vehicle conditions is realized.

In addition, the color of the track in the motion track graph can be changed based on the current vehicle and the real-time distance of the coming vehicle, and the color can accurately reflect the danger degree of the coming vehicle in real time so as to accurately warn a driver of the current vehicle.

Based on the same inventive concept as the method, the invention also provides a system for detecting the potential safety hazard of the road curve driving, which is shown in fig. 10 and comprises the following steps: a power supply, an OLED (Organic light emitting semiconductor) Display screen, and a processor.
