Description
본 발명은 자동차 급발진 사고를 방지하기 위하여 고안된 전자 제어 장치이다. 자동차 사고란 생명과 직결되므로 이를 방지하기 위하여 다중 방지 장치가 필수적이 되었다. 언제 일어날지 모르는 급발진을 적절히 대처하기 위해서는 브레이크 페달을 밟았을 경우에만 시동이 걸리게 되고 시동후 급발진 상태의 고장이 일어나면 제어회로1에서 이를 감지하여 경고용 브레이크등이 점등됨과 동시에 엔진 속도를 즉시 저속으로 억제시킨다. 상기와 같은 상태로 자동차를 도로변에 주차시킬 수 있는 시간동안은 시동을 저속으로 유지시키고 잠시후 자동으로 엔진을 정지시킨다. 위와 같은 상태에서 급발진 현상이 일어나면 제어회로2에서 이를 감지하여 즉시 엔진을 정지시킨다.The present invention is an electronic control device designed to prevent an accident of automobile acceleration. Since car accidents are directly related to life, multiple prevention devices have become necessary to prevent them. In order to cope with sudden start, which may happen at any time, start is only applied when the brake pedal is pressed.In case of a sudden start after a start, the control circuit 1 detects this and turns on the warning brake and lights up the engine speed immediately. Suppress it. In the above state, the vehicle is kept at a low speed for a time that the vehicle can be parked on the roadside and the engine is automatically stopped after a while. If sudden start occurs in the above condition, the control circuit 2 detects this and immediately stops the engine.
위와 같이 급발진 고장의 상황을 근본적으로 대처할 수 있게 하여 사고시 적절히 대처함을 목적으로 고안된 것에 특징이 있다.As described above, it is characterized by being designed for the purpose of coping with accidents by fundamentally coping with the situation of sudden oscillation failure.
일반적으로 수출용 차량에 장착된 것으로 알려진 방법은 브레이크를 밟고 시동을 걸어야만 시동이 걸리는 장치가 있는가 하면 시동 초기에 급발진 고장이 나타나므로 시동 초기 최대 15초까지 스로틀 밸브에 과도한 공기가 들어가지 않도록 한 공기 차단 장치. "6월 25일 스포츠조선 정보란".(상기 방법은 급발진과 관계없이 시동을 걸때마다 스로틀 밸브에 공기 흐름을 막아 심한 매연 등 유해 물질을 배출시킴) 또는 엔진 rpm이 갑자기 급상승하는 것을 감지하여 자동차를 멈추게 하는 방법이 있으나 주행중 엔진 rpm 급상승은 빈번히 일어나므로 해결책이 되지 못한다. 퀵스타트(운전자가 브레이크를 이용하여 급가속하는 기술)를 할 때 최고 rpm까지 올라가거나, 또는 급경사 지에서 엔진 브레이크를 걸었을 때 운전자의 의도와 관계없이 엔진 rpm이 공회전에서 +1500rpm까지 급상승한다.In general, a method known to be mounted on an export vehicle is a device that requires a brake and a start to start, while a sudden start failure occurs at the start of the start, so that the air to prevent excessive air from entering the throttle valve up to 15 seconds at the start of the start. Blocking device. "Jun 25 Sports Chosun information" (regardless of sudden start, the method prevents the flow of air to the throttle valve every time the vehicle is started, and releases harmful substances such as severe smoke) or by detecting the sudden increase in the engine rpm of the car There is a way to stop the engine, but the engine rpm spike frequently occurs while driving, so this is not a solution. When starting a quick start (a technology in which the driver uses the brake to accelerate), or when the engine brakes on a steep slope, the engine rpm jumps from idle to +1500 rpm regardless of the driver's intention.
위와 같이 고속 주행중인 자동차가 갑자기 멈추면 뒤따라오는 차량에 의해 사고로 이어진다. 상기와 같은 방법으로는 급발진을 막을 수가 없다. 실례로 아파트 단지 내에서 주행중 급발진 사고(1999년6월7일 MBC 아침뉴스)를 당한 춘천의 L씨, 또는 탤런트 K씨의 BMW같은 고급 승용차가 브레이크를 밟은 상태로 인사 사고를 낸 것은 급발진 때는 브레이크 제동만으로는 자동차를 멈출 수가 없으면 급발진은 시동 초기 15초내가 아니라 주행 중에도 일어날 수 있으므로 이와 같은 방법은 근본 대책이 아니라고 사료된다.If a car driving at a high speed suddenly stops as described above, the following vehicle leads to an accident. Sudden oscillation cannot be prevented by the above method. For example, a high-end car, such as Mr. L of Chuncheon or Mr. Talent K, BMW, who suffered a sudden accident while driving in an apartment complex (MBC Morning News on June 7, 1999), had a personnel accident while braking. If braking alone does not stop the car, it is considered that such a method is not a fundamental measure because rapid start may occur during driving, not within 15 seconds of starting.
먼저 브레이크를 밟은 상태에서만 시동이 가능하도록 하고 시동 후 엔진 rpm이 정상적이 아닌 급발진 상황이 감지되면 자동으로 급가속중인 엔진을 즉시 저속으로 낮추어 준다. 만약 운전자의 조정에 의해 엔진 rpm이 급상승했을 때는 엔진이 멈추지 않는다. 이때는 운전자가 과속 주행 중인 상태이며 운전자의 의도와 달리 차량이 멈추게 되면 뒤따라오는 차량에 의하여 사고로 연결되기 때문이다. 차량의결함에 의해 엔진 rpm이 급상승하거나 급발진 상태가 되면 이를 감지하여 자동으로 엔진 rpm을 급감속시켜 엔진 공회전 상태와 같은 저속으로 유지시키며 동시에 급발진 상태를 알리는 경보음이 울리게 되고 뒷차량에 고장을 알리는 경고로 브레이크등이 점등된다.The engine can be started only when the brake is applied first, and then the engine is rapidly lowered to low speed immediately when the engine rpm is detected as a sudden acceleration condition after starting. If the engine rpm increases rapidly due to driver adjustment, the engine will not stop. This is because the driver is in a state of overspeed driving and, unlike the intention of the driver, when the vehicle is stopped, it is connected to an accident by the following vehicle. When the engine rpm increases or suddenly starts to be detected by the fault of the vehicle, it detects this and automatically decelerates the engine rpm to keep it at the same low speed as the engine idling state. The warning lamp lights up as a warning.
따라서 저속 상태로 차량을 갓길에 주차할 수 있도록 1~2분 경과 후 자동으로 엔진은 멈추게 된다. 1차 제어장치와 2차 제어장치로 분리시키는 것은 1차 제어장치 동작으로 갑자기 차량이 멈추면 뒷차에 의해 충돌하게 되므로 이를 경고한 뒤 2차로 완전 정지하게 하여 사고를 미연에 방지하기 위한 것이며, 1차 제어 후 만약을 대비하여 2차 제어 장치로 엔진을 완전 정지케 하는 장치이다. 위와 같이 급발진 상황에 근본적으로 대처할 수 있도록 고안된 것에 특징이 있다.Therefore, the engine stops automatically after one or two minutes to park the car on the shoulder at low speed. Separating between the primary control unit and the secondary control unit is to prevent the accident by stopping the vehicle completely after the warning because it is collided by the rear car when the vehicle suddenly stops due to the primary control device operation. It is a device to stop the engine completely by the secondary control device in case of car control. It is characterized by the fact that it is designed to fundamentally cope with the sudden onset situation.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
브레이크 통제부(시동회로A)의 계전기(L3)의 접점 14,16이 개방되어 있으므로 IG(점화코일)과 PS(연료펌프)의전압이 차단되어 있어 시동이 걸리지 않는다. 따라서 브레이크 페달을 밟으면 브레이크 스위치단자에 연결된 D10. D9.에 의해 계전기(L3)를 ON시켜 접점 14,16이 도통 되며 (IG),(PS)의단자가 어스되어 시동이 걸리게 된다.실리콘다이오드 D9는 브레이크 페달을 놓았을 때 계전기(L3)를 ON시키기 위한 전원 공급용이다. 고장에 의한 급발진으로 엔진rpm이 급상승하면 (P)단자에 검출된 rpm신호는 제어회로1의 VR1으로 조정된 신호는 C1,D1. 상기 D1에 의해 C2가 충전되어 상기 Q1의 바이어스 전압으로 공급된다. 상기 트랜지스터 Q1의 바이어스 전압 값은 R2:R3으로 결정되며 일정 값의 엔진 rpm에 의해 Q1,Q2가 ON, OFF된다. 상기 Q1,Q2는 급발진 상태의 엔진 회전에 의해 ON되고 따라서 계전기(L1)가 ON된다. 상기(L1)에 의해 계전기 접점 1,2와 D2에 의해 계전기(L1)는 계속 ON상태가 되고 상기 D2라인과 D3라인 사이의 일 점에 연결된 D5 상기D5에 연결된 급발진 경고용 버저가 울리게 되고 상기 D3에 연결된 브레이크등 좌우 등이 점등된다. 이와 동시에 (L1)접점3,5에 의해 솔레노이드 밸브(SB)단자에 전압이 걸리게 되고 상기 솔레노이드 밸브는 ON되어 밸브가 닫히게 되므로 저속 회전(≒1000rpm)에 필요한 미량의 연료만 공급된다.(공회전 상태의 엔진은 750±100rpm이다.)상기 저속 상태에서 접점4, 라인에 연결된 R6. 상기R6에 연결된 타이머B는 C6의 방전 시간 동안 계전기(L5)는 ON된다. 상기C6의 방전 시간 1~2분후 계전기(L5)는 OFF되어 접점 6,7에 의해 라인에 연결된 D4에 (+)전압을 공급하여 Q3,Q4를 구동시키고 계전기(L2)를 ON시켜 접점 10,11을 단락 시키므로 (IG),(PS)의전압이 차단되어 엔진은 정지된다.상기 제어회로 2의 VR2,C3,D4,C4는 2차 제어장치의 rpm감지용이다. 운전자가 급가속한 급발진 상황은 운전자가 가속페달을 밟아서 이루어지므로 이때는 가속페달 스위치(SW1)가 ON되어 상기(SW1)에 직렬 연결된 포토커플러(PT)가 ON된다.The contacts 14 and 16 of the relay L3 of the brake control unit (starting circuit A) are open, so that the IG (ignition coil) and PS (fuel pump) The voltage is cut off to prevent starting. Therefore, when you press the brake pedal, the brake switch D10 connected to the terminal. By turning on relay L3 by D9., Contact 14,16 is turned on and (IG), (PS) The terminal is earthed to start up. Silicon diode D9 is for supplying power to turn on relay L3 when the brake pedal is released. When the engine rpm suddenly rises due to a sudden start due to a failure, the rpm signal detected at the (P) terminal is adjusted to VR1 of the control circuit 1, and the signals C1 and D1. C2 is charged by D1 and supplied to the bias voltage of Q1. The bias voltage value of the transistor Q1 is determined as R2: R3, and Q1 and Q2 are turned on and off by a constant engine rpm. The Q1 and Q2 are turned on by the engine rotation in the rapid start state, and thus the relay L1 is turned on. The relay L1 continues to be turned on by the relay contacts 1,2 and D2, and the sudden warning buzzer connected to the D5 D5 connected to one point between the D2 and D3 lines is sounded by the L1. The left and right brake lights connected to D3 light up. At the same time, solenoid valve (SB) by (L1) contact 3, 5 Since voltage is applied to the terminal and the solenoid valve is turned on to close the valve, only a small amount of fuel necessary for low speed rotation (≒ 1000 rpm) is supplied. (In the idle state, the engine is 750 ± 100 rpm.) R6 connected to the line. In the timer B connected to the R6, the relay L5 is turned on during the discharge time of the C6. After 1 ~ 2 minutes of discharge time of C6, relay L5 is turned off, supplying (+) voltage to D4 connected to the line by contacts 6 and 7, driving Q3, Q4 and turning on relay L2 to contact 10, Shorts 11 to (IG), (PS) The voltage is cut off and the engine is stopped. VR2, C3, D4, and C4 of the control circuit 2 are for detecting the rpm of the secondary control device. The rapid acceleration and deceleration situation in which the driver accelerates is performed by the driver stepping on the accelerator pedal. At this time, the accelerator pedal switch SW1 is turned on and the photocoupler PT connected in series with the switch SW1 is turned on.
상기(PT)라인에 연결된 D11,D12는 PT에 의해 어스 되고 D11,D12는 Q1과 Q3의 바이어스 전압을 소멸시켜 Q1,Q2,Q3,Q4,(L1),(L2)가 OFF상태로 유지되므로 자동차의 기능은 원래의 상태로 된다. 따라서 급가속 유무에 관계없이 자동차는 정상적으로 동작된다. 이와 같은 상황에서 급발진이 발생하면 운전자는 가속 페달을 놓거나 브레이크를 밟게 되므로 (제어회로1),(제어회로2)에 의해 즉시 급발진을 해제시키게 된다. 위와 같은 급발진 사고는 주로 시동 초기에 일어나므로 (타이머A)에 의해 필요한 일정시간만 동작되게 할 수도 있고 (SW2)에 의해 계속 동작하게 할 수도 있다. 여기서는 10~15분 정도 회로가 동작하도록 하였다. 타이머A의 시간조절은 R,C와 MOS형FET로 하였고 타이머 리셋 전압은 점화스위치(ST)단자에서 얻게 된다. 위와 같이 고안하여 자동 변속기 자동차와 수동 변속기 자동차에 관계없이 모든 자동차에 급발진 방지 장치로 사용될 수 있다. 본 발명은 상기한 바와 같은 목적을 달성할 수 있도록 한 유용한 발명이다.Since D11 and D12 connected to the (PT) line are earthed by PT and D11 and D12 dissipate the bias voltages of Q1 and Q3, Q1, Q2, Q3, Q4, (L1) and (L2) remain OFF. The car's function is in its original state. Therefore, the car operates normally with or without a sudden acceleration. When sudden acceleration occurs in such a situation, the driver releases the accelerator pedal or depresses the brake, so the sudden acceleration is released by (control circuit 1) and (control circuit 2). Since the rapid start-up accident occurs mainly at the beginning of the startup, it may be allowed to operate only a predetermined time required by (Timer A) or may continue to operate by (SW2). In this case, the circuit operates for about 10 to 15 minutes. Timer A's time is controlled by R, C and MOS type FETs. Timer reset voltage is obtained from ignition switch (ST) terminal. Designed as above, it can be used as a sudden start prevention device for all cars regardless of automatic transmission car and manual transmission car. The present invention is a useful invention for achieving the above object.
이상에서 상술한 바와 같이 본 발명은 단일 방지 장치가 아닌 일어날수 있는 모든 상황에 근거하여 적절히 대처한 방지 장치들을 하나로 체계화하여 그 목적을 달성함에 있어 발명의 효과를 극대화시켰다.As described above, the present invention maximizes the effects of the present invention in achieving the object by systematically combining preventive devices that have been properly dealt with based on all possible situations, rather than a single preventive device.
그러므로 어떠한 성황의 급발진 자동차도 해결될 수 있는 다중 방지 장치로써의 기능을 가질 수 있는 것이다.Therefore, any rush car can have a function as a multiple prevention device that can be solved.
