Referring to FIG. 5, the speed of the own vehicle 101 is compared with the reference value to determine whether the own vehicle 101 is driven (S501). When the speed of the own vehicle is equal to or greater than the reference value, the magnetic vehicle ( Determining that the vehicle 101 is driving, the lane change determination unit 220 detects whether or not the counterpart vehicle 102 changes the lane (S502). In this case, when it is detected that the opponent vehicle 102 changes lanes, it is determined whether the opponent vehicle 102 and the vehicle 101 are located within a danger distance in which a collision risk exists. If the distance between the vehicles 303 is determined to be within a dangerous distance within the blind spot, information about the presence of the vehicles within the dangerous distance within the blind spot is simultaneously transmitted to the magnetic vehicle 101 and the counterpart vehicle 102 (S504). Both drivers of the magnetic vehicle 101 and the opponent vehicle 102 may prevent a vehicle accident.
이때, 상기 거리 정보 전달시(S504) 경고음을 통해 상기 자기 차량(101)의 운전자 및 상대 차량(102)의 운전자에게 사각지대 내 위험거리 내에 상기 차량들이 있음을 전달하고, 차량간 무선 통신을 통해 차량간 거리정보를 상기 자기 차량(101) 및 상대 차량(102)에게 동시에 전송하도록 함으로서, 상기 자기 차량(101) 및 상대 차량(102) 주행자 모두 사고에 대비할 수 있도록 할 수 있다.In this case, when the distance information is transmitted (S504), the driver of the vehicle 101 and the driver of the counterpart vehicle 102 are transmitted to the driver of the vehicle within the danger distance within the blind spot through the warning sound, and through the inter-vehicle wireless communication. By transmitting the distance information between the vehicle to the magnetic vehicle 101 and the opponent vehicle 102 at the same time, both the driver of the magnetic vehicle 101 and the opponent vehicle 102 can be prepared for an accident.
