Abstract

본 발명은 차량에 구비되는 크루즈 컨트롤시스템의 안전거리확보 장치 및 제어방법에 관한 것으로, 종래의 크루즈 컨트롤시스템기능만으로는 운전자가 고속도로 주행시 차량의 전방 또는 후방에서 주행중인 차량이 안전거리내로 가까이 접근할 경우에 졸음등으로 전압 시야를 확보하고 있지 못함으로 인해 발생되는 충돌사고를 방지할 수 없게 되는 문제점을 해소하기 위하여, 차량용 바디(1)의 전측 및 후측 소정부위에 초음파센서(4, 7)를 각각 구비하여 전, 후방에서 주행중인 차량이 안전거리내로 가까이 접근함에 따라 차량의 엔진제어부(9)에 의해 차량의 엔진속도를 자동으로 감속시키거나 가속작용을 하게 함으로써 충돌을 방지할 수 있게 되는 효과가 있다.The present invention relates to a safety distance securing device and a control method of the cruise control system provided in the vehicle, the conventional cruise control system function only when the driver is approaching within the safety distance when the vehicle driving in front of or behind the vehicle when driving on the highway In order to solve the problem that it is impossible to prevent a collision accident caused by failing to secure the voltage field due to drowsiness or the like, the ultrasonic sensors 4 and 7 are respectively disposed on the front and rear predetermined portions of the vehicle body 1, respectively. As the vehicle running in front and rear approaches close to the safety distance, the engine control unit 9 of the vehicle automatically reduces or accelerates the engine speed of the vehicle, thereby preventing collisions. have.
