Blind spot warning method and device based on cooperation of inter-vehicle communication

Abstract

The invention relates to a method for giving a warning on a blind spot of a vehicle based on V2V communication. The method includes steps: (a) if a rear video of a first vehicle is acquired from a rear camera, a first blind-spot warning device transmitting the rear video to a blind-spot monitor, to determine whether nearby vehicles are in the rear video using a CNN, and output first blind-spot monitoring information of determining whether the nearby vehicles are in a blind spot; and (b) if second blind-spot monitoring information of determining whether a second vehicle is in the blind spot, isacquired from a second blind-spot warning device of the second vehicle, over the V2V communication, the first blind-spot warning device warning that at least one of the second vehicle and the nearbyvehicles is in the blind spot by referring to the first and the second blind-spot monitoring information.

Description

technical field [0001] The present invention relates to a blind spot warning system for a vehicle, and more particularly, to a system for warning a blind spot based on inter-vehicle communication in cooperation with surrounding vehicles. Background technique [0002] Usually, in order to secure a field of view by observing the side and the rear when the driver changes lanes while the vehicle is running, exterior mirrors are installed on both sides of the vehicle and an interior mirror is installed in the center of the vehicle interior. [0003] The exterior mirrors are installed on both sides of the vehicle to ensure side visibility and rear visibility, and there are blind spots where vehicles or objects driving close to the side cannot be recognized. [0004] Therefore, when the driver changes lanes without confirming that another vehicle is following closely beside the running vehicle, there is a problem that a collision accident with another vehicle driving in the blind s...

AI Technical Summary

Problems solved by technology

[0010] However, in the existing blind spot warning system, the position information of vehicles using the Global Positioning System (GPS) is shared through inter-vehicle communication, but there is a problem of driving between high-rise buildings with low position accuracy, cloudy days, tunnels, etc. Problems with blind spots not being accurately warned in the environment

[0011] In addition, in the existing blind spot warning system, if the lens of the rear camera installed at the rear of the vehicle is contaminated by water droplets, etc., there is a problem that the blind spot cannot be accurately warned.

[0012] In addition, in the existing blind spot warning system, when driving at night when the illumination is low, there is a problem that the blind spot warning cannot be performed because the object detection performance based on the image of the rear camera is low.
