Description

The blockage of the road aware the road structure of vehicles}

The present invention relates to a road structure capable of recognizing a lane departure of a vehicle, and more particularly, to a lane of a vehicle that can recognize a lane departure through vibration of a vehicle body when the lane is separated from a driving lane during operation of the vehicle. The road structure that can recognize the departure.

In general, the purpose of the vehicle is a vehicle as a means for the user's convenience. For this purpose, automobiles are not only a means of transportation but they are becoming an integral part of not only their own life but also social life. With this social trend, the number of car owners has increased steadily, and our case has already exceeded 10 million.

As mentioned above, the number of automobiles has already entered the ranks of developed countries, but it is well known that automobile accidents proportional to the population have the world's No. 1 disgrace. This results in significant economic losses, both nationally and personally.

On the other hand, there are various types of car accidents such as mechanical defects, carelessness of the driver, drowsy driving, and drunken driving. In particular, car accidents caused by drowsy driving caused by long periods of work, tired work due to heavy work, and drunken driving may result in negligence in frontal driving, deterioration of perceptual ability to recognize the danger of accidents, and accidents. Due to the late response to coping, it is not uncommon for accidents to lead to catastrophic accidents that directly lead to personal injury.

Therefore, research and development for reducing accidents by preventing drowsy driving itself as described above are in progress. As a result of these research efforts, technologies such as a lane departure prevention system have been developed to enable the real-time processing of lane departure by calculating the real width of the lane image signal inputted by driving the driving lane. In addition, images of the lanes in front of the vehicle are taken and processed, the type of lanes, the number of lanes, the width of the roads, the driving speed, and the like are detected and compared with the operation map of the navigation unit. Some technologies, such as lane departure prevention systems, determine and alert.

In addition to the technology described above, a lane departure prevention system that detects a driver's heartbeat and detects it as a drowsiness by comparing it with a normal heartbeat and drives the vibrator inside the seat to wake up the driver or issue a warning sound to warn the driver. In addition, a pressure sensor is installed on the back of the driver's seat to detect the driver's drowsiness and to warn the driver of the driver's drowsiness.

However, the lane departure prevention techniques as described above are expensive because they require expensive equipment and systems and high-precision technology, and have a problem in that they are difficult or economically burdened for practical application to a vehicle.

In addition, the lane departure prevention techniques as described above are applied only to the vehicle, and only the driver of the vehicle to which the lane departure prevention technique is applied may benefit, and many other drivers may not benefit. That is, there is a problem that the above-described technologies are not technologies that can be widely used for many drivers.

In addition, the lane departure prevention technologies described above require expensive equipment and systems and advanced and precise technologies, as described above, and can only be benefited by the driver of the vehicle to which the lane departure prevention technology is applied. Therefore, there is a problem that it is not a fundamental solution in reducing accidents caused by drowsy driving.

On the other hand, in addition to the accidents caused by drowsy driving as described above, in general, the road structure of the road is also caused by the reflection of poor visibility of the driver's lane due to abnormal weather such as night driving and heavy rain or heavy snow.

The present invention has been devised to solve the problems described above, by forming an uneven groove larger than the width of the car wheels at equal intervals on the road and shoulder road drowsy driving, night and abnormal weather If the vehicle leaves the lane due to poor visibility of the driving lane that may be caused by such reasons, the driver may leave the lane by causing the vehicle body to vibrate by the irregularities formed between the uneven groove and the road surface. The purpose of the present invention is to provide a road structure capable of recognizing a lane departure of a vehicle.

Another object of the present invention may occur by causing the vehicle body to be vibrated by the unevenness between the uneven groove and the road surface formed at equal intervals when the car leaves the lane so that the driver can recognize the fact that the vehicle has left the lane. It is to prevent accidents in the future and to reduce loss of life and property.

Another object of the present invention is to cause the vehicle to vibrate by the unevenness between the uneven groove and the road surface formed at equal intervals when the car leaves the lane so that the driver can recognize the fact that they have left the lane. In addition to preventing possible accidents, it is also possible to reduce personal and national economic losses by preventing road congestion that can occur.

In addition, the present invention, in addition to the above-mentioned purposes, it is possible to consistently implement a vehicle accident prevention policy due to poor visibility of driving lanes that may occur due to drowsy driving, nighttime and abnormal weather, etc. It is to fundamentally prevent accidents.

Furthermore, the present invention forms an uneven groove having a width greater than the width of the wheel of the car at equal intervals on the road surface of most driving lanes and shoulders, so that the uneven groove when the car leaves the lane while the vehicle is running. By vibrating the vehicle body by the irregularities between the road and the road surface, the driver can recognize the fact that he has left the lane so that most drivers and the people who drive on the road can benefit.

The present invention configured to achieve the above object is as follows. That is, the road structure that can recognize the departure of the vehicle according to the present invention is the width of the left and right on the outer peripheral surface of the roller drum is larger than the width of the wheel of the car, while rolling the roller equipment formed with semi-circular protrusions at equal intervals 3 The car is separated from the driving lane due to the poor visibility of the driving lane during the driving of the car by forming a number of semicircular irregular grooves at equal intervals in the driving lane of the unsteady asphalt pavement or the road surface of the shoulder. In this case, the vehicle body is vibrated up and down by a plurality of uneven grooves formed at equal intervals so that the driver and passengers can recognize the fact that the vehicle is out of the driving car.

In the above-described configuration, it is preferable that the left and right widths of the uneven groove are formed at 600 to 900 mm, the front and rear width is 25 to 30 mm, the center depth is 13 to 30 mm, and the distance from the front and rear uneven groove longitudinal center to the longitudinal center is 200 to 300 mm.

Hereinafter will be described in detail with respect to the road structure that can recognize the lane departure of the vehicle according to a preferred embodiment of the present invention.

1 is a plan view showing a general road lane structure.

First, prior to explaining the road structure that can recognize the lane departure of the car according to the present invention will be described the general road structure as follows. That is, as shown in FIG. 1, in the general road 100, driving lanes 120 are formed at both sides with a central separation line 110 interposed therebetween. The driving lane 130 is divided by, and the shoulder 140 is formed on the outside of the driving lane 120.

The general road 100 having the structure as described above cannot be recognized by the driver and passengers when the driving lane 120 leaves the driving lane 120 due to poor visibility of the driving lane that may be caused by the driver's drowsy driving, nighttime, and after waking up. It is structured.

Therefore, a large number of accidents occur due to poor driving visibility due to drowsy driving, nighttime, abnormal weather, etc., resulting in large-scale accidents. The following shows the road of the structure to recognize the departure of the car by improving the road structure as shown in FIG.

Figure 2 is a plan view showing a road structure that can recognize the lane departure of the vehicle according to the present invention, Figure 3 is an enlarged view showing "A" of Figure 2, Figure 4 is to recognize the lane departure of the vehicle according to the present invention Longitudinal sectional view showing the road structure.

On the other hand, Figures 2 to 4 is a road structure that can recognize the lane departure of the vehicle according to the present invention is a running lane of the asphalt pavement 100 while rolling the roller equipment formed with a semi-circular protrusions on the drum outer peripheral surface at equal intervals By forming a plurality of semi-circular uneven grooves 150 in the longitudinal direction of the road surface 120 or the shoulder 140 is formed by forming the unevenness (凹凸) between the uneven groove 150 and the road surface. At this time, the pavement road 100, which may form the uneven groove 150 as described above, is a new asphalt pavement road 100 that has not yet been solidified.

More specifically, the road structure capable of recognizing a lane departure of a vehicle according to the present invention is a roller equipment having a semicircular protrusion formed at equal intervals with a width of right and left larger than that of a car wheel on a roller drum outer circumferential surface. By rolling through a plurality of semi-circular uneven grooves 150 at equal intervals on the road surface of the road lane 120 or shoulder road 140 of the new asphalt pavement 100 is not hardened in the state of finishing the third compaction Concave-convex (凹凸) is formed between the concave-convex groove 150 and the road surface.

As described above, the semi-circular protrusions on the outer circumferential surface of the roller drum are rolled through the roller equipment formed at equal intervals, and the driving lane 120 or the shoulder road 140 of the new unpaved asphalt pavement 100 is finished. By forming the semicircular uneven groove 150 along the pavement 100 on the road surface and hardening the uneven groove 150 due to poor visibility of the driving lane that may occur due to drowsy driving of the driver, nighttime and abnormal weather. In the case of leaving the driving lane 120, the vehicle body may be vibrated up and down by the unevenness between the uneven groove 150 and the road surface, thereby allowing the driver and passengers to recognize the departure of the driving lane 120 of the vehicle. Make sure

At this time, as in the above-described configuration is formed in a semi-circular shape on the road surface of the running lane 120 or shoulder road 140 of the new asphalt pavement 100 is not solidified by the force of the roller pressurized state Concave-convex groove 150 is a width of the left and right is generally larger than the width of the wheel of the car wheels of the car that is separated from the driving lane 120 repetitive irregularities (凹凸) between the concave-convex groove 150 and the road surface To go up and down.

Meanwhile, in the present invention, the left and right widths of the uneven groove 150 are 600 to 900 mm, the front and rear widths of the uneven groove 150 are 25 to 65 mm, and the center depth of the uneven groove 150 is 13 to 30 mm and the uneven groove 150 before and after. ) The distance from the longitudinal center to the longitudinal center was formed from 200 to 300 mm. As a result of the vibration test of the vehicle body on the pavement road 100 where the uneven groove 150 is formed, the uneven groove 150 as described above is a pavement road in a residential area. It was found that it is suitable for (100). That is, in a residential area where civil complaints are caused by the vibration and noise of the vehicle body, the vibration and noise of the vehicle body should be relatively small, so that the front and rear widths of the uneven groove 150 need to be relatively small.

As described above, although the vibration and noise of the vehicle body are relatively small, the uneven groove 150 is formed when the driving lane 120 leaves the driving lane 120 due to poor visibility of the driving lane that may occur due to drowsy driving, nighttime and abnormal weather of the driver. The noise generated by the vibration and vibration transmitted to the vehicle body when passing the road surface can be said to have a great effect on the driver and passengers in recognizing the departure of the driving lane 120 of the vehicle.

Therefore, as described above, the pavement road 100 having a structure in which the uneven groove 150 having a relatively small width before and after is formed at equal intervals may generally be effective for a small vehicle.

On the other hand, as described above, as a condition for forming the uneven groove 150 at equal intervals on the roadway 120 or the road surface of the shoulder road 140 of the new unpaved asphalt pavement 100 in the state of finishing the third compaction For asphalt pavements, the pavement thickness should be at least 60 mm. That is, when the pavement thickness of the asphalt pavement is less than 60mm, it may affect the pavement structure of the uneven groove 150 due to the pressure and impact of the automobile wheels.

On the other hand, as described above, the uneven groove of the structure formed on the road surface of the road lane 120 or shoulder 140 of the new unpaved asphalt pavement 100 in the state where the third compaction is completed 150 is generally suitable for pavement 100 in residential areas. That is, as described above, the width before and after the formation of the uneven groove 150 is relatively small, and the distance between the longitudinal center and the longitudinal center of the uneven groove 150 before and after is relatively far from the width before and after the uneven groove 150. This makes it possible to prevent civil complaints caused by vibration or noise damage by relatively reducing the effects of vibration and noise of the vehicle body.

The unevenness of the road structure according to the present invention, that is, the structure of the road surface 120 or the width of the shoulder 140 of the new asphalt pavement 100 that has not yet been solidified in the state of finishing the third compaction, is formed with a relatively small width. When the groove 150 is formed on the pavement 100, there is an advantage that the construction cost can be reduced.

The uneven groove 150 having the structure as described above may be formed on the road surface of the driving lane 120 or the shoulder 140 of the pavement 100, as well as the center of the road 100 of the structure without a central separator It may be formed along the separation line 110 at equal intervals.

As described above, according to the present invention, the uneven groove 150 of the road lane 120 and the shoulder 140 of the new unpaved asphalt pavement 100 in the state of finishing the tertiary compaction of the residential area at equal intervals in the longitudinal direction (150) ) To form a small width before and after the formation, and the distance between the longitudinal center and the front and rear recessed groove 150 and the longitudinal center is formed relatively wider than the front and rear width of the recessed groove 150, the driver's drowsy driving, night and abnormal weather, etc. When the vehicle leaves the driving lane 120 due to poor driving lane visibility that may occur, the driver and passengers are highly effective in recognizing that the driving lane 120 of the vehicle is separated by vibration and noise.

In addition, by forming the concave-convex groove 150 in the new asphalt pavement 100 in the residential area as described above, it is possible to relatively reduce the damage of vibration and noise to prevent civil complaints caused by the damage of vibration and noise.

The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the range allowed by the technical idea of the present invention.
