이하 첨부한 도면을 참조하여 본 발명의 실시예에 따른 동작을 상세히 설명하기로 한다.Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 충돌방지시스템 구성도를 도시한 것이며, 도 2는 본 발명의 실시예에 따른 장애물 충돌방지 제어흐름도를 도시한 것이다. 우선 도 1을 참조하면, 물체감지센서(10)는 자동차 전방 및 후방에 위치한 장애물(자동차를 포함함)을 감지할 수 있도록 자동차 프론트 범퍼 및 리어 범퍼에 각각 설치되어 사정거리내 물체감지시 그에 따른 물체감지신호를 발생하여 출력한다. 상기 물체감지센서(10)로는 레이더시스템에서 적용되고 초음파기술을 이용하여 구현할 수 있다. 차속센서(20)는 현재 차속을 전기적신호로 변환하여 출력한다. ECU(Electronic Control Unit)(30)는 도 2에 도시한 바와 같은 제어프로그램이 저장된 롬(ROM)을 구비함으로써 본 발명의 실시예에 따른 충돌방지시스템의 동작을 전반적으로 제어한다. 예를 들면, ECU(30)는 상기 물체감지센서(10)로부터 입력되는 물체감지신호를 연산처리하여 장애물과의 거리(하기 설명에서는 상기 장애물로써 주행중인 자동차를 상정하여 설명하기로 한다), 즉 차간거리를 산출하고 산출된 차간거리가 후술한는 안전거리, 제동거리범위,급제동거리범위내에 포함되는가를 검색하여 자동차의 차속을 제어한다. 한편 제동부(40)는 상기 ECU(30)로부터 입력되는 제동제어신호에 따라 동작하여 자동차의 차속을 감속 및 제동시킨다. 이러한 제동부(40)는 ECU(30)에 의해 제어되는 공지된 ABS 시스템을 사용할 수 있다. 안전거리지시 LED(50)는 상기 ECU(30)에 의해 제어됨으로써 점등 및 소등되고, 제동거리지시 LED(60)와 급제동거리지시 LED(70) 역시 상기 ECU(30)에 의해 점등 및 소등된다. 이러한 LED(50,60,70)는 인스트루먼트 패널에 설치된다. 한편 상기 안전거리지시 LED(50)는 전방에 주행중인 자동차가 안전거리 이상 이격되어 있다는 것을 지시하기 위한 LED이며, 제동거리지시 LED(60)는 전방에서 주행중인 자동차가 최저 안전거리와 최대 급제동거리 사이(이를 제동거리 범위내로 정의한다)에 위치하고 있다는 것을 지시하기 위한 LED이다. 그리고 급제동거리지시 LED(70)는 전방에 주행중인 자동차가 최대 급제동거리내(이를 급제동거리범위로 정의한다)에 위치하고 있다는 것을 지시하는 LED로 사용된다. 이와 같이 안전거리, 제동거리범위, 급제동거리범위를 구획하는 이유는 현재 주행중인 자동차의 차속을 고려하여 안전한 제동거리를 확보하기 위함이다. 따라서 상기 ECU(30)내의 롬에는 차속에 따라 안전거리, 제동거리범위, 급제동거리범위를 각각 대응시켜 놓은 테이블(이하 안전거리확보 테이블이라 정의한다)이 저장된다. 차간거리 경보 스위치(SW)(80)는 인스트루먼트 패널에 설치되며 스위치 누름동작에 의해 구비된 램프가 점등 및 소등되어 운전자에게 충돌방지시스템의 동작개시를 지시하여 준다. 한편 스로틀 위치센서(85)는 액셀러레이팅 페달의 조작상태를 감지하여 이를 전기적신호로 변환출력한다.1 is a block diagram of a collision avoidance system according to an exemplary embodiment of the present invention, and FIG. 2 is a block diagram of a collision avoidance control flow diagram according to an embodiment of the present invention. First, referring to Figure 1, the object sensor 10 is installed on the front bumper and the rear bumper of the car so as to detect the obstacles (including the car) located in the front and rear of the car, respectively, according to the object detection within the range Generates and outputs an object detection signal. The object detecting sensor 10 may be applied to a radar system and implemented using ultrasonic technology. The vehicle speed sensor 20 converts the current vehicle speed into an electrical signal and outputs it. The ECU (Electronic Control Unit) 30 controls the overall operation of the collision avoidance system according to the embodiment of the present invention by having a ROM in which a control program as shown in FIG. 2 is stored. For example, the ECU 30 calculates and processes the object detection signal input from the object detection sensor 10, so that the distance to the obstacle (in the following description, assuming a vehicle driving as the obstacle will be described), namely The vehicle speed is calculated by calculating the distance between vehicles and searching whether the calculated distance is included in the safety distance, the braking distance range, and the sudden braking distance range. Meanwhile, the brake unit 40 operates according to a brake control signal input from the ECU 30 to decelerate and brake the vehicle speed of the vehicle. This brake 40 may use a known ABS system controlled by the ECU 30. The safety distance instruction LED 50 is turned on and off by being controlled by the ECU 30, and the braking distance instruction LED 60 and the sudden braking distance instruction LED 70 are also turned on and off by the ECU 30. These LEDs 50, 60, 70 are installed in the instrument panel. Meanwhile, the safety distance command LED 50 is an LED for indicating that the vehicle driving in front is spaced more than the safety distance, and the braking distance command LED 60 indicates that the vehicle driving in front is the minimum safety distance and the maximum braking distance. It is an LED to indicate that it is located in between (defined within the braking distance range). In addition, the sudden braking distance indicating LED 70 is used as an LED indicating that the vehicle driving ahead is located within the maximum sudden braking distance (which is defined as the sudden braking distance range). The reason for partitioning the safe distance, the braking distance range, and the sudden braking distance range is to secure a safe braking distance in consideration of the vehicle speed of the currently running car. Therefore, the ROM in the ECU 30 stores a table (hereinafter, referred to as a safety distance securing table) corresponding to a safety distance, a braking distance range, and a sudden braking distance range according to the vehicle speed. Inter-vehicle distance warning switch (SW) (80) is installed in the instrument panel and the lamp provided by the switch pressing operation is turned on and off to instruct the driver to start the operation of the collision avoidance system. Meanwhile, the throttle position sensor 85 detects an operation state of the accelerator pedal and converts it into an electrical signal.

이하 도 1 및 도 2를 참조하여 본 발명의 실시예에 따른 충돌방지 제어방법을 상세히 설명하면 다음과 같다.Hereinafter, a collision prevention control method according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

우선 본 발명의 실시예에 따른 충돌방지시스템은 자동차의 진행방향에 대하여 동작하며, 하기 설명에서는 자동차가 전방으로 진행하는 것으로 가정하기로 한다. 이러한 가정하에서 ECU(30)는 90단계에서 인스트루먼트 패널에 구비된 각종 스위치를 스캔하여 차간거리 경보 SW(80)가 스위칭 "온"상태인가를 검사한다. 검사결과 상기 SW가 스위칭 "온"상태이면 ECU(30)는 92단계로 진행하여 물체감지센서(10)를 통해 물체감지신호를 입력받아 전방에 위치한 자동차와의 차간거리를 산출한다. 이때 차속센서(20)로부터는 계속적으로 차속감지신호가 입력된다. 차간거리를 산출한 ECU(30)는 94단계로 진행하여 산출된 차간거리가 현재 차속에 대응하는 최대 제동거리를 초과하는가를 검사하여 초과하면 96단계로 진행한다. 92단계에서 산출된 차간거리가 최대 제동거리를 초과한다는 것은 제동거리범위를 초과하였다는 의미로, 현재 주행중인 자동차가 전방에 위치한 자동차와 안전거리를 유지하고 있다는 의미로 해석할 수 있다. 따라서 ECU(30)는 96단계에서 안전거리지시 LED(96)를 점등시킨후 90단계로 되돌아가 계속적으로 90단계 내지 94단계를 수행한다. 만약 94단계에서 상기 산출된 차간거리가 최대 제동거리 이하라면 ECU(30)는 98단계로 진행하여 상기 산출된 차간거리가 최대 제동거리와 최대 급제동거리 사이의 값인가를 검사한다. 즉, ECU(30)는 98단계에서 상기 산출된 차간거리가 제동거리범위 내에 속하는 값인가를 검사하는 것이다. 검사결과 산출된 차간거리가 제동거리범위 내의 값이라면 ECU(30)는 100단계로 진행하여 제동거리지시 LED(60)를 점등시킨다. 그리고 102단계로 진행하여 제동제어신호를 출력함으로써 자동차의 속도를 감속시킨후 90단계로 되돌아가 상술한 90단계 내지 98단계와 100단계를 반복 수행한다. 한편, 98단계에서 차간거리가 최대 급제동거리 이하라고 판단되면 ECU(30)는 104단계로 진행하여 급제동거리지시 LED(70)를 점등하는 동시에 제동신호를 출력하여 자동차를 급제동시킨다. 이후 ECU(30)는106단계로 진행하여 스토틀 위치센서(85)를 통해 액셀 페달의 조작이 있는가를 검사하여 액셀 페달의 조작이 있으면 108단계로 진행한다. 그리고 108단계에서 제동부(40)로 출력중인 제동제어신호를 차단함으로써 제동을 해제시킨다. 그리고 다시 90단계로 되돌아가 상술한 충돌방지 제어방법을 반복 수행한다. 만약 90단계에서 상기 차간거리 경보 SW(80)가 스위칭 "오프"되면 ECU(30)는 본 발명의 실시예에 따른 충돌방지 제어방법을 종료하고 점등되어 있는 램프를 소등시킨다.First, the collision avoidance system according to the embodiment of the present invention operates with respect to the driving direction of the vehicle. Under this assumption, the ECU 30 scans the various switches provided in the instrument panel in step 90 to check whether the inter-vehicle distance warning SW 80 is in the switched "on" state. As a result of the inspection, when the SW is in the switched "ON" state, the ECU 30 proceeds to step 92 and receives the object detection signal through the object detection sensor 10 to calculate the distance between the vehicle and the vehicle located in front. At this time, the vehicle speed detection signal is continuously input from the vehicle speed sensor 20. The ECU 30 having calculated the inter-vehicle distance proceeds to step 94 and checks whether the calculated inter-vehicle distance exceeds the maximum braking distance corresponding to the current vehicle speed, and proceeds to step 96. If the inter-vehicle distance calculated in step 92 exceeds the maximum braking distance, it means that the braking distance range is exceeded, and it can be interpreted that the currently running car maintains a safety distance with the vehicle in front of it. Therefore, the ECU 30 turns on the safety distance indicating LED 96 in step 96 and then returns to step 90 to continuously perform steps 90 to 94. If the calculated inter-vehicle distance is less than or equal to the maximum braking distance in step 94, the ECU 30 proceeds to step 98 and checks whether the calculated inter-vehicle distance is a value between the maximum braking distance and the maximum braking distance. That is, the ECU 30 checks whether the calculated inter-vehicle distance falls within a braking distance range in step 98. If the calculated inter-vehicle distance is a value within the braking distance range, the ECU 30 proceeds to step 100 to light up the braking distance indication LED 60. In step 102, the vehicle is decelerated by outputting a braking control signal, and the process returns to step 90, and the above steps 90 to 98 and 100 are repeated. On the other hand, if it is determined in step 98 that the inter-vehicle distance is less than or equal to the maximum sudden braking distance, the ECU 30 proceeds to step 104 and turns on the sudden braking distance indicating LED 70 and outputs a braking signal to suddenly brake the car. Thereafter, the ECU 30 proceeds to step 106 and checks whether the accelerator pedal is operated by the stottle position sensor 85 and proceeds to step 108 when there is an operation of the accelerator pedal. In operation 108, the brake is released by blocking the braking control signal output to the brake unit 40. In step 90, the anti-collision control method is repeatedly performed. If the inter-vehicle distance warning SW 80 is switched "off" in step 90, the ECU 30 terminates the collision avoidance control method according to the embodiment of the present invention and turns off the lamp which is turned on.
