Abstract

본 발명은 자동차에 관련된 것으로, 특히 차량 주행시 전후방 차량과의 거리를 측정하여 전후방 차량과의 충돌위험을 사전에 방지하기 위한 차량충돌방지장치에 관한 것이다. 종래의 차량 충돌방지장치는 수동조작으로 전방차량과의 안전거리를 유지해야 되거나 후방차량과의 관계를 고려하지 않아 여전히 사고발생의 위험이 있었다. 본 발명의 차량충돌방지장치는 차량의 앞부분과 뒷부분에 거리측정센서를 부착하고 거리측정센서에서 측정된 전후방 차량과의 거리 및 상대적인 접근속도를 계산하여 충돌위험이 있을 경우 자동으로 브레이크가 작동되게 하였다. 본 발명의 차량충돌방지장치는 차량을 안전운전을 위해 차량에 설치되어 사용된다.The present invention relates to a vehicle, and in particular, to a vehicle collision prevention device for preventing the collision risk with the front and rear vehicles in advance by measuring the distance to the front and rear vehicles when driving the vehicle. Conventional vehicle collision avoidance device has to maintain the safety distance with the front vehicle by manual operation or do not consider the relationship with the rear vehicle, there was still a risk of accidents. The vehicle collision avoidance device of the present invention attaches a distance measuring sensor to the front and rear of the vehicle and calculates the distance and relative approach speed with the front and rear vehicles measured by the distance measuring sensor so that the brake is automatically activated when there is a danger of collision. . The vehicle collision prevention apparatus of the present invention is installed and used in a vehicle for safe driving of the vehicle.
