자동변속기 차량의 차량 급발진 방지방법{SUDDEN ACCELERATION PREVENTION METHOD IN AUTO GEARSHIFT VEHICLE}How to prevent sudden start of vehicle of automatic transmission vehicle {SUDDEN ACCELERATION PREVENTION METHOD IN AUTO GEARSHIFT VEHICLE}

본 발명은 자동변속기 차량의 차량 급발진 방지방법에 관한 것으로 더욱 상세히는, 자동변속기 차량에 설치된 변속레버를 P→R, N→R, P→D 또는 N→D로 조작할시의 차속을 감지하여 일정속도 이하이고, 스로틀밸브 개폐량이 "0"인데 엔진 회전수(RPM)가 일정값 이하이면 변속패턴상의 기어(1st)를 결정하고 이를 만족하지 못하면 급발진로 판정하여 연료공급 개통에 설치된 전 솔레노이드밸브를 차단하여 모든 클러치를 해제함과 동시에 기어를 중립(N)상태로 만들고 인디케이터를 점멸시켜 급발진으로 인한 인한 안전사고의 발생을 미연에 방지할 수 있도록 함과 동시에 소비자가 빠른 시간내에 아프터 서비스를 받을 수 있도록 발명한 것이다.The present invention relates to a method for preventing a sudden start of a vehicle of an automatic transmission vehicle, and more particularly, by detecting a vehicle speed when a shift lever installed in an automatic transmission vehicle is operated by P → R, N → R, P → D or N → D. If the speed is below a certain speed and the throttle valve opening / closing amount is "0" but the engine speed (RPM) is below a certain value, the gear (1st) on the shift pattern is determined. To release all clutches, make the gears in neutral (N) state, and flash the indicator to prevent the occurrence of safety accidents due to sudden start and to receive after-sales service as soon as possible. It is invented to be.

최근들어 자동변속기가 장착된 자동차에서 그 원인은 정확히 밝혀지지 않은 가운데 변속레버의 변환시 운전자의 의사와 무관하게 급가속이 이루어져 많은 재산상의 피해는 물론 인명피해를 주게 되는 일이 종종 발생되고 있어 사회적으로 큰 문제화되고 있다.Recently, the cause of the automatic gearbox is not known exactly. However, when the shift lever is changed, the acceleration is rapidly accelerated regardless of the driver's intention, which often causes many property damages and damages to society. It is a big problem.

이와같은 자동변속기가 장착된 자동차의 이상 급가속 현상에 의한 사고 예방 시스템으로 종래에 가장 널리 사용되고 있는 기술은 변속레버 락 방식인데, 이는 운전자가 브레이크 패달을 밟아야만 변속레버가 드라이브(D) 레인지 상태에서 다른 레인지로 변환되도록 고안된 시스템이다.The most widely used technology for preventing accidents caused by abnormal acceleration of a vehicle equipped with such an automatic transmission is the shift lever lock method, in which the shift lever is in the drive (D) range only when the driver presses the brake pedal. The system is designed to convert from one range to another.

그러나, 우리나라에서 자동차를 제조하고 있는 각사는 그 제작 비용이 비싸다는 이유로 이와같은 변속레버 락 방식 마져 우리나라에 시판되고 있는 자동차에는 거의 적용하지 않고 주로 수출용 차량에만 적용되고 있는 실정이다.However, the companies that manufacture automobiles in our country, because of the high manufacturing cost, such a shift lever lock method is not applied to the cars marketed in Korea, the situation is mainly applied only to export vehicles.

따라서, 현재 국내에서 시판되고 있는 자동변속기 자동차에서는 이상 급가속 현상에 의한 사고발생에 무방비한 상태에 있는 것이다.Therefore, the automatic transmission vehicle currently in the domestic market is defenseless against accidents caused by abnormal acceleration.

뿐만 아니라, 디젤엔진은 과거 기계식 연료분사 펌프를 이용하는 방식에서, 환경규제의 강화에 따른 기술개발에 힘입어 전자제어 시스템이 개발되고, 이로 인하여 상용차 뿐만 아니라 점차 승용차에도 탑재되고 있는 추세이다.In addition, in the past, the diesel engine has a mechanical fuel injection pump, and an electronic control system is developed due to the development of technology in accordance with the strengthening of environmental regulations. As a result, the diesel engine is gradually installed in a passenger car as well as a commercial vehicle.

이와같은 디젤차량의 엔진출력은 가솔린엔진과 달리 연료량에 의해 제어되고, 또 엔진 회전수와 악셀개도에 의하여 미리 정해진 연료량을 분사하게 된다.Unlike the gasoline engine, the engine output of such a diesel vehicle is controlled by the amount of fuel, and the fuel amount is injected in advance by the engine speed and the accelerator opening.

여기서, 악셀개도량은 운전자가 악셀패달을 밟은 정도에 부응하여 변화되는 악셀개도 감지용 센서(즉, 악셀 패달센서)의 출력전압을 전자제어유니트에서 측정하여 판단하고 그 결과값에 부응하여 연료의 분사량을 결정하게 된다.Here, the accelerator opening amount is determined by measuring the output voltage of the sensor for detecting the accelerator opening (that is, the accelerator pedal sensor) that is changed in response to the driver's stepping on the accelerator pedal and measuring the output voltage of the fuel in response to the result. The injection amount is determined.

그런데, 종래의 디젤엔진 자동차(물론 자동변속기가 탑제된 디젤엔진 자동차)에는 상기와 같이 하나의 악셀 패달센서 출력값에 의존하여 전자제어유니트가 악셀의 개도량을 결정짓는 구성으로 되어 있음에 따라 만약, 운전자의 의지와 관계없이 악셀 패달센서에서 오류가 발생되어 실제로 검출되는 전압이 자체의 단선 및 단락으로 판정 않되는 영역에서 출력될 경우 상기 전자제어유니트는 이를 오류로 인식하지 못하고 그 전압에 부응하여 과다한 연료량을 분사시켜 급발진이 일어날 우려가 있다.However, according to the conventional diesel engine vehicle (a diesel engine vehicle equipped with an automatic transmission, of course), the electronic control unit determines the opening amount of the accelerator in accordance with the output value of one axel pedal sensor as described above. Regardless of the driver's intention, if an error occurs in the accelerator pedal sensor and the voltage actually detected is output in an area where it is not judged as its disconnection or short circuit, the electronic control unit does not recognize it as an error and responds excessively to the voltage. There is a fear that sudden oscillation may occur by injecting the fuel amount.

본 발명은 이와같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 자동변속기가 탑제된 모든 차량에 있어서 변속레버가 P→R, N→R, P→D 또는 N→D로 조작할될시의 차속을 감지하여 일정속도 이하이고, 스로틀밸브 개폐량은 "0"인데 엔진 회전수(RPM)가 일정값 이하이면 변속패턴상의 기어를 결정하고 이를 만족하지 못하면 급발진로 판정하여 연료공급 개통에 설치된 전 솔레노이드밸브의 차단을 통해 모든 클러치를 해제함과 동시에 기어를 중립상태로 만들어 급발진으로 인한 인한 안전사고의 발생을 미연에 방지할 수 있고, 또 소비자가 급발진 우려를 즉시 인지하고 빠른 시간내에 아프터 서비스를 받을 수 있는 자동변속기 차량의 차량 급발진 방지방법을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such problems in the related art. When the shift lever is operated by P → R, N → R, P → D or N → D in all vehicles equipped with an automatic transmission, Detects the vehicle speed and is below a certain speed, and the opening and closing amount of the throttle valve is "0". If the engine speed (RPM) is below a certain value, the gear on the shift pattern is determined. By disconnecting the solenoid valve, all the clutches are released, and the gears are in a neutral state, which prevents the accident from occurring due to sudden start and stops the customer from being immediately aware of the sudden start. It is an object of the present invention to provide a method for preventing vehicle sudden start of an automatic transmission vehicle.

상기한 본 발명의 목적은, 변속레버가 P→R, N→R, P→D 또는 N→D로 조작되면 차속을 감지하여 일정속도 이하이면 다시 스로틀밸브 개폐량을 감지하여 개폐량이 "0"이면, 이번에는 엔진 회전수(RPM)를 감지하여 일정값 이하이면 변속패턴상의 기어를 결정하되, 상기에서 스로틀밸브가 "0"이 아니거나 엔진 회전수가 일정값 이상이면 급발진로 판정하여 연료공급 개통에 설치되어 있는 모든 솔레노이드밸브의 차단시켜 모든 클러치를 해제함과 동시에 기어를 중립상태로 전환하고 포지션 인디케이터를 점멸시키도록 제어하므로써 달성할 수 있다.The object of the present invention described above, when the shift lever is operated by P → R, N → R, P → D or N → D, detects the vehicle speed and detects the throttle valve opening / closing amount again when the speed is below a certain speed so that the opening and closing amount is “0”. In this case, the engine speed (RPM) is sensed and the gear on the shift pattern is determined if it is below a predetermined value, but if the throttle valve is not "0" or the engine speed is above a certain value, it is determined as a rapid start and the fuel supply is opened. This can be achieved by shutting off all clutches of the solenoid valves installed in the valve, releasing all clutches, controlling the gears to neutral and flashing the position indicator.

따라서, 자동변속기 차량의 급발진을 미연에 방지하여 안전성을 확보할 수 있음은 물론 소비자가 빠른 시간내에 아프터 서비스를 받을 수 있는 것이다.Therefore, it is possible to secure safety by preventing sudden start and stop of the automatic transmission vehicle, and consumers can receive after-sales service in a short time.

이에 따르면, 전자제어 유니트(1)에서 변속레버 검출센서(2)를 통해 현재 변속레버가 P→R 또는 P→D 상태로 조작되는지를 검출하는 과정과;According to this, a process of detecting whether the current shift lever is operated in the state of P → R or P → D by the shift lever detecting sensor 2 in the electronic control unit 1;

상기에서 검출한 결과 변속레버가 P→R 또는 P→D 상태로 조작된 상태로 판정되면 차속센서(3)를 통해 현재 차속(VSP)이 정해진 속도(X km/h) 이하인지를 검출하는 과정과;If it is determined that the shift lever is operated in a state of P → R or P → D as a result of the detection, a process of detecting whether the current vehicle speed VSP is less than a predetermined speed (X km / h) through the vehicle speed sensor 3 and;

상기에서 검출한 결과 차속(VSP)이 정해진 속도(X km/h) 이하이면 스로틀밸브 개폐량 검출센서(4)를 통해 그 개폐량(TPS)이 "0"인지를 검출하는 과정과;Detecting whether the opening / closing amount TPS is "0" through the throttle valve opening / closing detection sensor 4 when the vehicle speed VSP is equal to or less than a predetermined speed (X km / h);

상기에서 검출한 결과 스로틀밸브 개폐량(TPS)이 "0"이면 엔진 회전수 검출센서(5)를 통해 그 회전수(RPM)를 감지하여 일정값(Y) 이하인지를 검출하는 과정과;If the throttle valve opening and closing amount TPS is "0", detecting the rotation speed RPM through the engine speed detection sensor 5 to detect whether the throttle valve opening and closing amount TPS is equal to or less than a predetermined value Y;

상기에서 검출한 결과 모두 만족하면 변속패턴상의 기어(1st)로 결정하는 단계와;Determining that the gear 1st on the shift pattern satisfies all the detected results;

상기에서 검출한 결과 스로틀밸브의 개폐량(TPS)가 "0"이 아니거나 엔진 회전수(RPM)가 일정값 이상(RPM≥Y)이면 급발진로 판정하고 솔레노이드 구동부(6)에연료공급 개통에 설치되어 있는 모든 솔레노이드밸브의 차단시키기 위한 출력신호를 발생시켜 모든 클러치를 해제함과 동시에 변속기 제어부(9)를 통해 기어를 중립상태로 전환하고 인디케이터 구동부(7)를 통해 포지션 인디케이터(8)를 점멸시키는 과정으로 이루어진 것을 특징으로 한다.As a result of the above detection, if the opening / closing amount TPS of the throttle valve is not "0" or the engine speed RPM is higher than a predetermined value (RPM≥Y), it is determined as a sudden start and the fuel supply opening to the solenoid drive unit 6 is performed. Generates an output signal to shut off all installed solenoid valves, releases all clutches, shifts gears to neutral through the transmission control unit 9, and flashes the position indicator 8 through the indicator drive unit 7. Characterized in that the process consisting of.

이때, 상기 연료공급 개통도는, 도 1에 도시한 바와 같이 오토 트랜스미션 플로이드(ATF)(11)가 오일펌프(12)에 의해 밸브바디 유로(13)를 따라 솔레노이드밸브(14)(15)들을 걸쳐 3-4개의 드라이빙 클러치(16)와 2-3개의 브레이크 클러치(17)로 이송되고, 충진된 클러치는 동력을 전달하거나 고정시키는 역할을 하도록 구성되어져 있다.At this time, the fuel supply opening degree is, as shown in Figure 1, the automatic transmission float (ATF) 11 is the solenoid valve 14, 15 by the oil pump 12 along the valve body flow path (13) It is conveyed to three to four driving clutches 16 and 2-3 brake clutches 17, and the filled clutch is configured to transmit or fix power.

이와같은 과정으로 이루어진 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made of such a process as follows.

먼저, 소정의 제어프로그램을 통해 차량의 전장품들에 대한 동작을 포함한 전반적인 제어기능을 수행하는 전자제어 유니트(1)에서는 엔진에 시동이 걸려지면 초기 변속레버 검출센서(2)를 통해 현재 변속레버가 P→R 또는 P→D 상태로 조작되는지를 계속 검출하게 된다.First, in the electronic control unit 1 which performs the overall control function including the operation of the electronic parts of the vehicle through a predetermined control program, when the engine is started, the current shift lever is transmitted through the initial shift lever detection sensor 2. It continues to detect whether it is operated in P → R or P → D state.

그 결과, 변속레버가 운전자에 의해 조작되어 P→R 또는 P→D 상태로 전환되면 이번에는 차속센서(3)를 통해 현재 차속(VSP)이 정해진 속도(X km/h: 예를들어 5km/h) 이하인지를 검출하여 만약 차속(VSP)이 정해진 속도(X km/h) 이하이면 이어서 스로틀밸브 개폐량 검출센서(4)를 통해 스로틀밸브의 개폐량(TPS)을 입력받아 그 상태가 "0"인지를 검출하게 된다.As a result, when the shift lever is operated by the driver to switch to the P → R or P → D state, this time the current vehicle speed VSP is determined by the vehicle speed sensor 3 (X km / h: for example, 5km / h). h) If the vehicle speed VSP is less than or equal to the predetermined speed (X km / h), the opening and closing amount TPS of the throttle valve is input through the throttle valve opening / closing detection sensor 4, and the state is " 0 "is detected.

이와같이 스로틀밸브 개폐량(TPS)을 검출한 결과 "0"이면 이번에는 엔진 회전수 검출센서(5)를 통해 엔진의 회전수(RPM)를 감지한 후 그 값이 일정값(Y: 예를들어 1200RPM) 이하인지를 비교 판단하게 된다.As a result of detecting the throttle valve opening / closing amount TPS as "0", the engine speed detection sensor 5 detects the engine speed RPM, and the value is a constant value (Y: 1200 RPM) or less.

상기 전자제어 유니트(1)에서 검출 내지 판단한 결과 상기한 조건을 모두 만족하면 정상상태로 인식하고 변속패턴상의 기어(1st) 즉, 운전자가 변속한 상태를 유지시켜 준다.이때, 변속기 팬턴상의 기어(1st)는 각각의 오토 트랜스미션 마다 체결 또는 해방하는 체결 요소들이 다르며, 여기서는 위의 조건을 만족하면 기존방식대로 스로틀밸브 개폐량 및 차속으로 이루어진 변속패턴 상의 기어를 선택하였다.As a result of detection or determination by the electronic control unit 1, if all of the above conditions are satisfied, it is recognized as a normal state and the gear 1st on the shift pattern, that is, the driver maintains the shifted state. 1st) has different fastening elements to be fastened or released for each auto transmission. Here, if the above conditions are met, gears on the shift pattern consisting of the throttle valve opening and closing speed are selected according to the conventional method.

그러나, 상기에서 검출한 결과 스로틀밸브의 개폐량(TPS)가 "0"이 아니거나 엔진 회전수(RPM)가 일정값 이상(RPM≥Y)이면 급발진 우려가 있는 것으로 판정하고 솔레노이드 구동부(6)에 차단신호를 출력시켜 연료공급 개통에 설치되어 있는 모든 솔레노이드밸브(14)(15)의 구동이 차단시되도록 하여 이에 연결된 모든 클러치 즉, 3-4개의 드라이빙 클러치(16)와 2-3개의 브레이크 클러치(17)를 해제함과 동시에 변속기 제어부(9)를 통해 기어를 중립상태로 전환하고 인디케이터 구동부(7)를 통해 포지션 인디케이터(8)를 점멸시켜 주게 된다.However, if the opening and closing amount TPS of the throttle valve is not " 0 " or the engine speed RPM is not lower than a predetermined value (RPM > Y), the solenoid drive unit 6 All the solenoid valves 14 and 15 installed in the fuel supply opening are shut off by outputting a shutoff signal to all the clutches connected thereto, that is, 3-4 driving clutches 16 and 2-3 brakes. At the same time as the clutch 17 is released, the gear is switched to the neutral state through the transmission control unit 9 and the position indicator 8 is flashed through the indicator driving unit 7.

따라서, 자동변속기 탑제 차량의 급발진 자체를 미연에 방지할 수 있어 급발진으로 인한 안전사고를 완벽히 차단할 수 있음은 물론, 운전자가 포지션 이디케이터(8)의 점멸 상태를 통해 급발진의 우려가 있음을 정확히 인식하고 빠른 시간내에 아프터 서비스를 요청할 수 있는 것이다.Therefore, it is possible to prevent the sudden start of the automatic transmission tower vehicle in advance, which can completely prevent safety accidents caused by the sudden start, and the driver can clearly know that there is a risk of sudden start through the blinking state of the position indicator 8. You can recognize and request after-sales service in a short time.

이상에서 설명한 바와 같이 본 발명에 의하면, 자동변속기가 탑제된 모든 차량에 있어서 변속레버가 P→R, N→R, P→D 또는 N→D로 조작될시 차속이 일정속도이하인 상태에서 스로틀밸브 개폐량이 "0"이 아니거나, 엔진 회전수(RPM)가 일정값 이상이면 급발진 우려가 있는 것으로 판정하고 연료공급 개통에 설치된 전 솔레노이드밸브의 차단을 통해 모든 클러치를 해제함과 동시에 기어를 중립상태로 만들어 주므로써 급발진으로 인한 인한 안전사고의 발생을 미연에 방지할 수 있고, 또 소비자가 인디케이터를 통해 급발진 우려를 인지하고 빠른 시간내에 아프터 서비스를 받을 수 있어 신뢰도를 대폭 향상시킬 수 있는 등 매우 유용한 발명인 것이다.As described above, according to the present invention, in all vehicles equipped with an automatic transmission, when the shift lever is operated by P → R, N → R, P → D, or N → D, the throttle valve is operated when the vehicle speed is below a certain speed. If the opening or closing amount is not "0" or the engine speed (RPM) is over a certain value, it is determined that there is a risk of sudden start and release of all clutches by blocking all solenoid valves installed in the fuel supply opening and the gears in a neutral state. It is possible to prevent the occurrence of safety accidents due to sudden oscillation in advance, and it is very useful for consumers to recognize the fear of sudden oscillation through indicators and to receive after-sales service in a short time, greatly improving the reliability.
