The operation of the vehicle collision avoidance system according to the present invention will be described.

The time when the vehicle approaching 30km / h at 10m distance and the vehicle approaching 60km / h at 30m distance from the point where the vehicle collision prevention system 100 is installed according to the present invention reaches the vehicle collision prevention system 100, respectively It is about 1.18 seconds and about 1.80 seconds, which causes two vehicles to pass through the vehicle collision avoidance system 100 at an interval of 0.62 seconds so that no collision between the two vehicles occurs. However, a vehicle approaching at 30 km / h at a distance of 10 m and a vehicle approaching at 60 km / h at a distance of 20 m from the installation point of the vehicle collision avoidance system 100 may not have time to reach the installation point of the vehicle collision avoidance system 100. It is almost the same as about 1.18, which causes a collision between two vehicles. Therefore, the vehicle collision prevention system 100 according to the present invention effectively prevents and installs a collision between the straight vehicle and the entry vehicle by displaying the positions and speeds of the vehicles 3 and 4 between the straight lane 1 and the entry lane 2. It can provide useful information for drivers of many vehicles at low cost.

In addition, in order to prevent the collision of the vehicles 3 and 4 between the straight lane 1 and the entry lane 2, both the distance and the speed of the vehicles 3 and 4 must be known, and the radar module using the Doppler effect is formed. By detecting the speed and the distance of the vehicle 3 and 4 in real time by the first and second vehicle detection units 110 and 120, collision between vehicles or two-wheeled vehicles in the driveway or intersection can be prevented.
