Abstract

본 발명은 차량의 주행시 갑작스런 전방장애물의 출현 등과 같은 돌발상황 하에서는 제동동작이 용이하게 수행하지 못할 뿐만 아니라 이를 부주의하게 인식하지 못하는 경우에는 추돌사고가 불가피하게 발생될 수 있다는 사정을 감안하여 이루어진 것으로, 차량의 주행시에 전방에 장애물이 근접한 상태를 검출하게 되면 엔진의 회전수(RPM)를 감소시키면서 제동동작이 수행될 수 있도록 하는 전방장애물감지시 차량의 제동장치를 제공한다.The present invention has been made in consideration of the fact that a braking operation may not be easily performed under sudden conditions such as sudden appearance of an obstacle in front of the vehicle, and a collision accident may inevitably occur if it is not inadvertently recognized. When the vehicle detects a state in which an obstacle is close to the front of the vehicle, the braking device of the vehicle at the time of detecting a front obstacle to perform a braking operation while reducing the engine speed (RPM) is provided.

그에 따라 본 발명은, 차량의 시동에 따른 시동스위치(2)의 스위칭동작에 의해 동작가능하게 되어 초음파의 송/수신동작에 의해 전방장애물의 근접거리를 감지하는 거리감지수단(4,6,8,10)과, 그 거리감지수단(4,6,8,10)으로부터의 근접거리 감지치에 의거하여 전방장애물의 근접상태를 검출하는 장애물검출수단(12,14), 그 장애물검출수단(12,14)으로부터의 검출치를 판독가능한 디지털신호 형태로 변환하는 ADC(16,18), 그 ADC(16,18)을 통해 전방장애물의 근접검출치를 입력받아 차속감지부(20)와 차속감지에 따른 차속감지신호와 비교/연산하여 엔진회전수의 감소를 위한 제어를 수행함과 더불어, 제동동작의 수행상태를 제어하는 ECU(22), 상기 ECU(22)에 의해 제어되어 엔진부(24)에 엔전회전수를 감소시키기 위한 RPM감소제어를 수행하는 엔진제어수단(26), 상기 ECU(22)에 의해 제어되어 강제적인 제동동작을 위해 구동되는 강제제동구동수단(28) 및 그 강제제동구동수단(28)의 구동에 의해 브레이크페달(100)을 강제적으로 제동하기 위한 브레이크수단(30)을 더 구비하여 구성된 것을 특징으로 한다.Accordingly, the present invention is enabled by the switching operation of the start switch 2 according to the start of the vehicle, the distance sensing means (4, 6, 8) for detecting the proximity distance of the front obstacle by the ultrasonic transmission / reception operation 10 and obstacle detection means 12 and 14 for detecting the proximity state of the front obstacle based on the proximity distance detection value from the distance detection means 4, 6, 8, and 10, and the obstacle detection means 12; (14) converts the detected values from the 14 into a readable digital signal, and receives the proximity detection value of the front obstacle through the ADCs (16, 18) according to the vehicle speed detecting unit (20) and the vehicle speed detection. The ECU 22 and the ECU 22 control the execution state of the braking operation and control the engine speed by comparing / computing with the vehicle speed detection signal and reducing the engine speed. Engine control means 26 for performing RPM reduction control for reducing the total rotation speed, the ECU 22 And a brake means 30 for forcibly braking the brake pedal 100 by the driving of the forced braking driving means 28 and the forced braking driving means 28, which are controlled and driven for a forced braking operation. Characterized in that configured.
