When exceeding, it is determined that an error occurs and the driver is notified by voice and the fuel amount can be controlled and corrected to the normal RPM area to prevent sudden start and the occurrence of safety accidents caused by the automatic transmission vehicle.

Recognizing and detecting whether local (CHK_01 AND CHK_02) is "true";
상기에서 검출한 결과 로컬(CHK_01 AND CHK_02)="참"이면 악셀페달 포지션 센서(1)의 출력신호를 입력받아 조작각도를 센싱하여 악셀페달의 조작각도에 맞는 허용 RPM을 확인함과 동시에 엔진 회전수 검출센서(3)를 통해 현재 차량 엔진의 RPM을 검출하여 차량의 RPM이 허용 RPM 보다 큰지를 검출하는 단계와;If local (CHK_01 AND CHK_02) is "true", the output signal from the Axel pedal position sensor 1 is sensed and the operating angle is sensed to confirm the allowable RPM corresponding to the operating angle of the accelerator pedal and to rotate the engine.

Notifying the driver of the occurrence of the abnormal state through the notification unit 11; characterized in that consisting of.
이와같은 구성 및 단계로 이루어진 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made of such a configuration and steps as follows.
먼저, 소정프로그램을 통해 자동차 전장부의 전반적인 제어를 실시하는 전자제어 유니트(5)에서는 통상시 차속센서(2)를 통해 자동변속기 차량의 속도를 센싱하여 차량이 정지상태인지를 검출하게 된다.First, the electronic control unit 5 which performs overall control of the automotive electronic part through a predetermined program detects whether the vehicle is in a stopped state by sensing the speed of the automatic transmission vehicle through the vehicle speed sensor 2 normally.
즉, 급발진은 자동차가 주행중에 이루어지는 것이 아니고, 정지된 상태에서 초기 출발할시 이루어지므로 자동차의 정지상태를 먼저 판단하게 된다.That is, the rapid start is not made while the car is running, but is made when the vehicle starts for the first time and the vehicle stops first.
상기 전자제어 유니트(5)에서 검출한 결과 차량이 정지상태가 아니면 차속이 20km이하인지를 검출하여 그 이하도 아니면 정지시의 변수값(CHK_01)을 "거짓(FALSE)"으로 인식(즉, 차량이 정지된 상태에서 부터 출발된 상태가 아님으로 인식)하고 초기과정으로 돌아가게 되는데, 이는 자동차가 주행중에 브레이크를 작동시켜 정지상태로 들어갈 수도 있고, 이미 20km 이상으로 주행중일 수도 있기 때문이다.As a result of the detection by the electronic control unit 5, if the vehicle is not in the stopped state, the vehicle speed is detected to be 20 km or less, and if it is less than or less, the variable value CHK_01 at the stop is recognized as "FALSE" (i.e., the vehicle It is recognized that the vehicle is not started from the stopped state), and the vehicle returns to the initial process, since the vehicle may brake and enter the stopped state while driving, or may be driving more than 20 km.
한편, 상기에서 검출한 결과 차량이 정지상태에 있거나, 차량이 정지상태에서부터 출발하여 20km 이하이면(즉, 초기 출발 상태에서 급발진이 일어날 가능성이 있는 속도 구간이면) 정지상태에서의 임의 변수값(CHK_01) 및 20km 이하일시의 변수값(CHK_2)을 각각 "참(TRUE)"으로 인지하고, 로컬(CHK_01 AND CHK_02)이 "참"인지를 검출하게 된다.On the other hand, if the vehicle is in the stationary state or the vehicle is 20km or less from the stationary state (that is, the speed range in which the rapid start may occur in the initial starting state), the random variable value CHK_01 is detected. ) And the variable value CHK_2 at 20 km or less are recognized as "true", respectively, and it is detected whether the local (CHK_01 AND CHK_02) is "true".
이와같이 상기 전자제어 유니트(5)에서 검출한 결과 로컬(CHK_01 AND CHK_02)="참"이면 악셀페달 포지션 센서(1)의 출력신호를 입력받아 운전자가 악셀페달을 조작한 각도를 센싱하여 악셀페달의 조작각도에 맞는 허용 RPM인지 확인(이때 허용 RPM은 차량의 특성에 맞도록 차량 메이커에서 기 설정해 놓은 것임)함과 동시에 엔진 회전수 검출센서(3)를 통해 현재 차량 엔진의 RPM을 검출하여 현재 차량의 엔진 RPM이 허용 RPM 보다 큰지를 검출하게 된다.As described above, when the electronic control unit 5 detects local (CHK_01 AND CHK_02) = true, the output signal of the axel pedal position sensor 1 is input to sense the angle at which the driver operates the axel pedal. Check whether the allowable RPM is suitable for the operation angle (at this time, allowable RPM is set by the vehicle manufacturer to suit the characteristics of the vehicle) and at the same time, detect the RPM of the current vehicle engine through the engine speed detection sensor (3). Will detect if the engine RPM is greater than the allowable RPM.
이와같이 검출한 결과 로컬(CHK_01 AND CHK_02)="참"이 아니거나, 현재 차량 RPM이 허용 RPM 미만이면 정상상태이므로 차속이 20 km 이하인지를 검출하는 단계로 되돌아간다.As a result of the detection, if it is not local (CHK_01 AND CHK_02) = "true" or if the current vehicle RPM is less than the allowable RPM, the process returns to the step of detecting whether the vehicle speed is 20 km or less.
그러나, 상기에서 검출한 결과 현재 차량의 RPM이 허용 RPM 보다 크면 연료이송 조절 유니트(8)를 구비하고 상기 연료 펌프(41)와 연료 공급부(7) 사이에 설치되어 있는 밸브(9)를 작동시켜 정상 RPM 이상으로 공급되는 연료는 연료 탱크(4)측으로 바이패스시키고 이상상태 알림부(11)를 작동시켜 운전자에게 이상 상태의 발생을 음성이나 램프 등으로 알려주어 신속한 대응을 할 수 있도록 한다.However, as a result of the above detection, if the current RPM of the vehicle is larger than the allowable RPM, the valve 9 provided between the fuel pump 41 and the fuel supply unit 7 is provided with the fuel feed control unit 8. The fuel supplied above the normal RPM is bypassed to the fuel tank 4 side and the abnormal state notification unit 11 is operated to notify the driver of the occurrence of the abnormal state by a voice or a lamp so as to quickly respond.
이때, 연료펌프(41)에서 펌핑된 연료는 전자제어 유니트(5)의 제어를 받는 연료 공급부(7)에 의해 필요량 이외에는 바이패스되고, 추가적으로 악셀 페달 조작각에 허용된 최대 RPM 초과시 연료 이송량은 연료이송 조절 유니트(8)를 구비하고 상기 연료 펌프(41)와 연료 공급부(7) 사이에 설치되어 전자제어 유니트(5)의 제어를 받는 밸브(9)에 의해 바이패스되므로 허용 PRM내로 엔진 회전수가 제어되어 급발진이 방지되는 것이다.At this time, the fuel pumped from the fuel pump 41 is bypassed other than the necessary amount by the fuel supply unit 7 under the control of the electronic control unit 5, and additionally, when the maximum RPM allowed for the accelerator pedal operation angle is exceeded, the fuel transfer amount is fuel. The engine speed is set within the allowable PRM because the valve is provided between the fuel pump 41 and the fuel supply unit 7 and is bypassed by the valve 9 controlled by the electronic control unit 5. It is controlled to prevent sudden start-up.
한편, 상기 밸브(9)는 기 알려진 ABS 브레이크의 압력조절 밸브와 동일하게 초당 수십번의 개폐를 실시하는 것이므로 이상현상(즉, 악셀 페달의 조작각도에 부응하지 않는 과다한 연료가 엔진으로 공급되므로 인한 급발진 발생 현상)을 정상으로 즉시 전환시킬 수 있는 것이다.On the other hand, since the valve (9) performs the opening and closing several times per second in the same way as the pressure regulating valve of the known ABS brake (i.e., the sudden start due to the excessive fuel that does not correspond to the operating angle of the accelerator pedal is supplied to the engine) Development phenomenon) can be returned to normal immediately.
이상에서 설명한 바와 같이 본 발명에 의하면, 자동변속기가 장착된 차량이 정지된 상태에서 20km까지 차속이 증가하는 동안 악셀페달의 조작각도를 감지하여 각 각도에 따른 허용 RPM을 초과할시 이상발생으로 판단하여 이를 운전자에게 음성등으로 즉시 알림과 동시에 연료량을 제어하여 정상 RPM 영역으로 자동 보정해 주므로써, 과다한 연료 공급으로 인한 급발진 및 그로 인한 안전사고의 발생을 미연에 방지할 수 있는 등 매우 유용한 발명인 것이다.As described above, according to the present invention, when the vehicle with the automatic transmission is stopped and the vehicle speed is increased up to 20 km, the operating angle of the accelerator pedal is sensed to determine an abnormality when the allowable RPM for each angle is exceeded. This is a very useful invention that prevents sudden start and excessive safety accidents due to excessive fuel supply by automatically notifying the driver with a voice and controlling fuel amount at the same time. .
