Description

Technical Field [0001] The present invention relates to a hazard warning transmission / reception device for vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle risk alert transmission / reception apparatus, and more particularly, to a vehicle risk alert transmission / reception apparatus that recognizes that an accident vehicle is stopped from a rearward approaching vehicle.

The safety distance between the rear vehicle and the front vehicle is generally specified according to the vehicle speed. That is, the vehicle interval is allowed to be 1 m when the vehicle is slowing down, and the vehicle interval is allowed to be 80 m when the vehicle is running at a high speed.

However, currently produced vehicles have a good running performance, and when the mileage is secured to a certain extent, the vehicle speed is higher than the interval of the vehicle, and the brakes are often suddenly applied just before the collision with the preceding vehicle. However, if the vehicle interval is maintained as long as the braking distance in spite of the sudden braking operation as described above, no collision occurs. However, if the braking distance is not secured, the collision can not be avoided.

However, if the braking distance of the rear vehicle is uncertain in a situation where the collision with the preceding vehicle can not be avoided, the collision can occur from the triple collision to the further collision. In addition, a vehicle collision accident may be caused by a driver's distance illusion.

That is, since the interval between the vehicle and the rear vehicle is checked through a rearview mirror or a room mirror, the interval between the front vehicle and the vehicle is made through the front glass, so that when the light is reflected or when rain or snow comes, A collision accident will occur.

Accordingly, there have been various excellent invention patents, such as a design for installing a warning lamp on the rear seat rack of a vehicle, a design for installing a safety reflector or a fault signboard on the inner side panel of the vehicle trunk, a design for displaying a fault signboard on a key of a trunk of a car, Due to the devise to attach to part of the vehicle, the problem that the performance and function of the safety signboard and the warning lamp are not fully exhibited due to the installation height problem, And

Korean Patent Laid-Open No. 1998-04092 (1998.08.17.) Confirms the speed of the rear vehicle and the distance between the vehicle and the rear vehicle. If the distance between the vehicle and the rear vehicle is smaller than the predetermined safety distance, Vehicle safety distance unrecognized warning device for preventing a collision according to a safety distance uncertainty by providing a device for reducing the distance between the vehicle and the rear vehicle, An emerging transmitter; A receiver for receiving the signal generated by the transmitter and reflected by the rear vehicle to convert the signal into an electrical signal; A distance sensing unit for sensing a time at which the signal is generated by the transmitter and a time difference between receiving the signal at the receiver and a distance to the rear vehicle; A speed sensing unit for sensing the speed of the rear vehicle by checking the difference between the current distance input from the distance sensing unit and the immediately preceding distance and the difference between the distances; A memory unit in which an inter-vehicle safety distance to be maintained according to a speed change of a rear vehicle is set; A control unit for reading the safety distance set for the speed input from the speed sensing unit from the memory unit and performing a control operation according to the vehicle distance at the current speed being less than the safety distance; And a warning lamp that is turned on under the control of the control unit and instructs the rear vehicle to decelerate. According to the disclosed technology, when the vehicle interval is smaller than the safety distance determined according to the speed of the rear vehicle, an automatic warning is issued to the rear vehicle so as to reduce the speed, thereby preventing a collision due to the safety distance uncertain, The reliability can be provided.

Korea Patent No. 10-1382873 (Apr. 21, 2014) proposed a vehicle detection and tracking function to warn a collision with a preceding vehicle simply by applying a modified Haar classification method to detect a candidate vehicle A front vehicle collision warning system and a front vehicle collision warning system which can improve reliability by distinguishing a vehicle and a surrounding environment other than the vehicle by verifying by filtering again. According to the disclosed technique, there is provided an image pickup apparatus comprising: a video image pickup unit attached to a front side of the vehicle and photographing the front of the vehicle; Receiving the image data from the image capturing unit, classifying the image data by a predetermined mask to find a candidate vehicle ahead, filtering the candidate vehicle to determine an actual vehicle object, A track is added to missed objects, a history is checked by overlapping the object of the current frame with the object of the previous frame, and a collision time is calculated on the basis of the checked result of the history based on the distance between the object and the vehicle A driving unit for generating a warning signal according to the collision time; And a warning unit for receiving the warning signal and generating a frontal vehicle collision warning signal.

In the conventional vehicle securing apparatus described above, an emergency indicator lamp is mounted at the rear of the vehicle in general, so that when a vehicle ahead of the vehicle stops on the road, the aft emergency indicator flashes to detect a dangerous situation in a vehicle approaching from behind, However, since the display position is low, the blinking state of the emergency indicator light of the forward accident vehicle can not be recognized at nighttime or when the weather deteriorates, resulting in the occurrence of large accident and personal injury due to multiple collision accidents.

The conventional vehicle securing apparatus described above is installed at a position of 100 m or more in the daytime when the vehicle is stationary due to a breakdown of the vehicle and is installed at an installation point of 200 m or more in the rear of the vehicle at night. However, Is not easy to install, and there is a problem that multiple collision accidents occur due to untimely notification to the rear vehicle immediately. In many cases, the driver of a vehicle does not even have a vehicle safety indicator, so that it does not require a lot of social cost to solve the above problems and can improve the problem of the vehicle risk warning using the existing safety indicator in real time and dramatically The need for a new approach has emerged.
