Description

자동차의 급발진 방지장치{Sudden departure prevention device for Automobile}Sudden departure prevention device for Automobile}

본 발명은 자동차의 급발진 방지장치에 관한 것으로서, 보다 상세하게는 차량의 급발진으로 인한 대형사고와 이로 인한 피해 발생이 방지될 수 있도록 한 자동차의 급발진 방지장치에 관한 것이다.The present invention relates to a sudden start prevention device for a vehicle, and more particularly, to a sudden start prevention apparatus for a vehicle to prevent a large accident and damage caused by the sudden start of the vehicle.

자동차의 급발진 현상은 자동변속 차량의 시동시나 정차 후 출발시 엔진의 회전속도가 급격하게 상승하여 급가속 되는 차량의 오작동 현상이다. 이러한 급발진 현상은 ECU에 비정상적인 전기신호가 전달되어 액셀 페달을 밟지 않아도 공회전상태에서 엔진회전수가 6,000rpm까지 올라가며 ECU의 제어오류에 의해 비정상적 동력 전달이 이루어져 발생되는 것으로 알려져 있다.The sudden start of a vehicle is a malfunction of a vehicle that is rapidly accelerated due to a rapid increase in the rotation speed of the engine when the automatic transmission vehicle starts or stops after starting. This sudden oscillation phenomenon is known to occur when the abnormal electrical signal is transmitted to the ECU, the engine speed rises to 6,000rpm in idle state without pressing the accelerator pedal, and the abnormal power transmission is caused by the control error of the ECU.

이러한 급발진사고는 매우 순간적으로 발생되기 때문에 운전자는 이에 적절하게 대응할 수 없으며, 제동장치를 구동하여도 급발진하는 차량의 속도를 제동시킬 수 없는 문제점이 있다. 따라서, 종래에는 이러한 급발진사고를 방지 및 예방하기 위해서 시동 및 출발시 엔진의 흡기다기관에 유입되는 공기를 제한하여 급발진을 방지하는 방법이 제안되고 있으나 이러한 방법은 운전자의 상황에 따라 급하게 출발해야 할 때에 출력이 제대로 나오지 않는 단점이 있었고 정차 후 출발시에 발생되는 급발진에 대해서는 방지책이 없는 문제점이 있었다.Since the sudden acceleration accident occurs very instantaneously, the driver cannot properly respond to this problem, and there is a problem in that the speed of the rapid starting vehicle cannot be braked even when the braking device is driven. Therefore, in order to prevent and prevent such sudden accidents, a method of preventing sudden start by limiting the air flowing into the intake manifold of the engine at the start and the start has been proposed. There was a disadvantage that the output did not come out properly, and there was a problem that there is no preventive measures against the sudden start occurring at the start after stopping.

또 다른 방법으로는 차량의 rpm을 시동후 지속적으로 감지하여 설정치 이상이 되면 고정 rpm으로만 주행될 수 있도록 차량의 속도를 제한하는 방법이 제안되고 있으나 이런 경우에도 앞지르기를 해야 하거나 스피드를 즐기기 위해 속도를 내어야 하는 경우에 운행의 제약을 받는 단점이 있다.As another method, it is suggested to limit the speed of the vehicle so that it can continuously run at a fixed rpm when the rpm of the vehicle is continuously detected after the start of the vehicle. However, in this case, it is necessary to overrun or speed to enjoy the speed. There is a disadvantage in that the operation is limited when it is necessary to pay.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 시동직후나 정차 후 출발시 소정시간 동안에 엔진의 rpm이 설정치 이상으로 상승되는 경우 자동으로 엔진작동이 정지되도록 하여 차량의 급발진이 방지될 수 있도록 한 자동차의 급발진 방지장치를 제공하는 것이다.The present invention is to solve the problems as described above, the object of the present invention is to start the engine automatically stops the engine operation is stopped when the engine rpm rises above the set value for a predetermined time when starting immediately after starting or after stopping It is to provide a vehicle sudden start prevention device so that this can be prevented.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 일실시예에 따른 자동차의 급발진 방지장치를 나타낸 블록구성도이다. 이를 참조하면, 상기 자동차의 급발진 방지장치는 급발진에 해당되는 최소 rpm을 설정하는 rpm설정부(2)와, 점화코일(30)과 연결되어 엔진의 실제 rpm을 측정하는 rpm측정부(4)와, 차륜 샤프트에 설치되어 그 회전유무를 감지하는 차륜회전감지부(6)와, 시동키박스의 전원라인과 연결되어 엔진작동에 필요한 각종 전기부품에 공급되는 전원을 온/오프시키는 전원차단스위치(8)와, 급발진 상황을 경보해주는 경보부(10)와, 상기 각 구성요소(2,4,6,8,10)와 연결되어 신호 입출력을 하는 제어부(12)로 이루어진다.1 is a block diagram showing a sudden start prevention device for a vehicle according to an embodiment of the present invention. Referring to this, the sudden start prevention device of the vehicle is an rpm setting unit (2) for setting the minimum rpm corresponding to the sudden start, the rpm measurement unit (4) connected to the ignition coil (30) to measure the actual rpm of the engine and A power switch for turning on / off the power supplied to various electric parts necessary for engine operation by being connected to the wheel rotation sensing unit 6 installed on the wheel shaft to sense the rotation thereof and the power line of the ignition key box; 8), an alarm unit 10 for alerting the sudden start situation, and the control unit 12 is connected to each of the components (2, 4, 6, 8, 10) for signal input and output.

상기 rpm측정부(4)는 점화코일(30)과 연결되어 점화신호에 포함된 노이즈를 제거하는 노이즈제거필터(31)와, 이 노이즈제거필터(31)를 통해 입력된 점화신호를 계수하여 rpm을 산출하는 계수기(32)로 이루어진다.The rpm measuring unit 4 is connected to the ignition coil 30 to remove the noise included in the ignition signal, and a noise filter 31, and counts the ignition signal input through the noise removal filter 31 rpm It consists of a counter 32 to calculate the.

상기 차륜회전감지부(6)는 차륜 샤프트에 자석을 설치하고 이 자석과 일정거리 이격되어 자력감지센서를 설치하여 차륜의 회전상태를 감지하게 된다. 이는 차량의 정차 후 출발을 인식하거나 차량 시동시 제어장치의 이상으로 비정상적인 동력전달이 이루어지는 것을 감지하기 위한 것이다. 즉, 통상 시동후 2초이내에 운전자의 자발적인 조작에 의해 차륜이 구동되기는 매우 어렵기 때문에 이 시간동안 차륜이 회전될 경우 이를 급발진으로 인식하기 위한 것이다.The wheel rotation detecting unit 6 installs a magnet on the wheel shaft and is spaced apart from the magnet by a predetermined distance to detect a rotation state of the wheel by installing a magnetic force sensor. This is for recognizing departure after stopping of the vehicle or detecting abnormal power transfer due to an abnormality of the control device when the vehicle starts. In other words, it is usually difficult to drive the wheel by spontaneous operation of the driver within 2 seconds after the start, so if the wheel is rotated during this time to recognize this as a sudden start.

상기 전원차단스위치(8)는 시동키박스의 전원라인과 연결되어 엔진 시동 및 공회전에 필요한 점화코일, 연료펌프. ECU 등의 각종 전기부품에 공급되는 전원을 온/오프하는 릴레이스위치가 적용가능하다.The power cut-off switch (8) is connected to the power line of the ignition key box ignition coil, fuel pump required for starting the engine and idle.

상기 제어부(12)는 상기 rpm설정부(2)와 연결되어 rpm설정부(2)를 통해 급발진에 해당되는 최소 rpm을 입력받는다. 또한, 상기 제어부(12)는 rpm측정부(4), 전원차단스위치(8), 경보부(10) 및 차륜회전감지부(6)와 각기 연결되어 시동시 또는 정차 후 출발시 약 10초 이내에 rpm측정부(4)로부터 감지되는 엔진의 rpm이 설정치 이상이거나, 시동후 약 2초 이내에 차륜회전감지부(6)로부터 차륜이 회전되는 것이 감지되면 상기 전원차단스위치(8)를 오프시켜 엔진작동을 정지시키게 된다.The control unit 12 is connected to the rpm setting unit 2 receives the minimum rpm corresponding to the rapid start via the rpm setting unit (2). In addition, the controller 12 is connected to the rpm measuring unit 4, the power cut-off switch 8, the alarm unit 10 and the wheel rotation detection unit 6, respectively, within about 10 seconds when starting or starting after stopping. When the rpm of the engine detected from the measuring unit 4 is equal to or greater than the set value, or when the wheel is rotated from the wheel rotation detecting unit 6 within about 2 seconds after starting, the engine shut-off switch 8 is turned off to operate the engine. Stopped.

도 2는 상기 실시예에 따른 자동차의 급발진 방지장치를 나타낸 플로우차트이다. 이를 참조하면, 시동후 약 2초 이내에 상기 차륜회전감지부(6)에 의해 차량의 주행이 감지되는가를 판단하여(단계 50), 차륜의 회전이 감지되면 전원차단스위치(8)를 오프시켜 엔진작동을 자동 정지시키고(단계54), 경보부(10)를 통해 급발진 상황을 경보해준다(단계 55).2 is a flowchart showing a sudden start prevention device for a vehicle according to the embodiment. Referring to this, it is determined whether the driving of the vehicle is sensed by the wheel rotation detecting unit 6 within about 2 seconds after starting (step 50), and when the rotation of the wheel is detected, the power cutoff switch 8 is turned off to engine The operation is automatically stopped (step 54), and the alarm unit 10 alerts the sudden start situation (step 55).

만일, 차량의 주행이 감지되지 않고 시동후 약 10초 이내이면,(단계 51) 상기 rpm측정부(4)를 통해 rpm을 측정하여(단계 52) 측정된 rpm이 설정 rpm이상이면(단계 53) 상기 전원차단스위치(8)를 오프시켜 엔진작동을 정지시키고(단계54), 경보부(10)를 통해 급발진 상황을 경보해준다.(단계 55)If the driving of the vehicle is not detected and within about 10 seconds after starting (step 51), the rpm is measured through the rpm measuring unit 4 (step 52), and if the measured rpm is greater than or equal to the set rpm (step 53). The power cutoff switch 8 is turned off to stop the engine operation (step 54), and the alarm unit 10 alerts the sudden start-up situation.

시동후 10초가 경과된 경우에는(단계 51) 측정 rpm이 설정rpm을 넘더라도 정상 주행되도록 한다.(단계 56)If 10 seconds have elapsed since the start-up (step 51), it is allowed to drive normally even if the measured rpm exceeds the set rpm.

또한, 정상주행 중 상기 차륜회전감지부(6)에 의해 정차 후 출발이 감지되는 경우에는(단계 57) 단계 51로 진행하여 동일한 동작을 수행한다.In addition, if the start after the stop is detected by the wheel rotation detecting unit 6 during normal driving (step 57), the process proceeds to step 51 to perform the same operation.

이상에서와 같이 본 발명에 의하면, 상기 자동차의 급발진 방지장치는 시동시나 정차 후 출발시 소정시간 동안에 설정rpm 이상으로 rpm이 상승되는 경우나 시동후 약 2초 이내에 차륜회전이 감지되면 자동으로 엔진작동이 정지되어 차량의 급발진이 방지되므로 이에 따른 대형사고와 이로 인한 피해 발생이 방지되며 차량의 신뢰성이 향상되는 효과가 있다. 또한, 시동후 운전자의 상황에 따른 급출발에 지장을 주지 않으며 주행중 속도를 내야 하는 경우에 운행에 제약을 받지 않는 장점이 있다.As described above, according to the present invention, the sudden start and stop device of the vehicle automatically starts the engine when the rpm rises above the set rpm for a predetermined time at the start or after the start or when the wheel rotation is detected within about 2 seconds after the start. Since the vehicle is prevented from being suddenly started by the stop, a large accident and damage caused by the vehicle are prevented and the reliability of the vehicle is improved. In addition, there is an advantage that does not interfere with the rapid start according to the driver's situation after starting and is not limited to the driving in the case of speeding up while driving.
