본 발명은 클러치스위치를 이용한 자동차를 출발 초기 감지 제어장치에 관한 것으로, 특히 자동차 출발 초기와 후진 초기를 각각 감지하여 연료 및 에어의 증가로 차량가속 성능 및 출발시 차량에 전달되는 을컥거리는 진동감을 배제시켜 정숙한 상태로 진행되게 한 것이다.The present invention relates to an initial detection control device for starting a vehicle using a clutch switch, and in particular, detects the initial start of the vehicle and the beginning of the reverse, respectively, and excludes the acceleration of the vehicle and the sense of vibration transmitted to the vehicle at the start by increasing the fuel and air. In order to proceed in a quiet state.

차량의 초기 출발 혹은 후진시는 통상 클러치와 결합과정에서 발생하는 로드 증가로 인해 엔진 성능의 저하 현상이 발생하였다.When the vehicle starts or retracts, the performance of the engine decreases due to the increase in the load normally generated during engagement with the clutch.

본 발명은 이러한 엔진 성능 저하를 방지하기 위해 클러치 페달 부위에 스위치를 장착, 클러치가 결합되는 시점 이전에 이를 감지하여 연료 및 에어를 보상함으로써 엔진 토오크를 높이고 출발시 차량의 가속 성능을 높이는데 있는 것이다.The present invention is to increase the engine torque by starting the switch to the clutch pedal portion, and to compensate for the fuel and air by detecting this before the clutch is coupled to prevent the engine performance deterioration and to increase the acceleration performance of the vehicle at the start. .

종래에는 자동차 출발시 엔진 RPM(REVOLUTIONS PER MINUTE) 저하에 따라 이를 보상하게 되어 있는데, 제 1 도에서 보는 바와 같이 출발시 엔진 RPM이 어느 일정 밴드(BAND)를 오버 드롭(OVER DROP)시 소프트웨어를 이용 에어를 보상하도록 구성되어 있다.Conventionally, the engine RPM (REVOLUTIONS PER MINUTE) at the start of the vehicle is compensated for this, as shown in FIG. 1, when the engine RPM at the start over a certain band (BAND) using the software when OVER DROP Configured to compensate for air.

그러나, 이와 같은 보상 방식은 엑셀 페달을 밟아 엔진 RPM의 상승이후 클러치를 결합할 경우에는 별 문제가 없었으나, 엔진 RPM 상승 이전에 클러치를 결합할 경우에는 엔진 RPM의 저하 현상이 발생하므로, 이때 에러를 보상하게 되면 엔진 토오크가 떨어지고 로드는 계속 증가하는 상태에서 간혹 시동이 꺼지는 현상이 발생할 위험이 있으며, 또한 시동이 꺼지지 않고 주행이 이루어졌다 하더라도 다시 클러치를 접속했을 경우에 갑작스런 로드 감소로 인하여 엔진 RPM이 상승하는 현상이 발생하여 운전자가 당황하는 경우가 종종 있었다.However, this compensation method has no problem when the clutch is coupled after the engine RPM is increased by stepping on the accelerator pedal. However, when the clutch is coupled before the engine RPM is increased, the engine RPM decreases. If the engine torque drops and the rod continues to increase, the engine may sometimes start off.In addition, the engine RPM may be reduced due to sudden load reduction when the clutch is reconnected even if the engine is driven without starting. This rising phenomenon often caused the driver to be embarrassed.

또, 이 분야에 관연한 종래 기술로는 일본 발명협회 공개기보 82-3101호가 알려져 있으나, 이는 각종 장치와 표시기를 설치하여 운전자가 최적 상태의 경제 운행을 하게 도와주는 구성이나 그 구성 자체가 운전 조건을 조정하는 기능이 없어 실용화되지는 못했다.In addition, Japanese Patent Publication No. 82-3101 is known as a related art related to this field, but it is a configuration that provides various devices and indicators to help the driver operate economically at optimum conditions, or the configuration itself is a driving condition. There was no function to adjust the power, so it was not put to practical use.

본 발명의 목적은 출발 초기시에 발생하는 로드 증가에 의한 엔진 성능의 저하 현상을 방지하여 승차감을 향상시키도록 자동조정되는 출발초기 감지 제어장치를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide an initial start detection control device which is automatically adjusted to improve ride comfort by preventing a decrease in engine performance due to an increase in load occurring at the beginning of departure.

이하, 본 발명을 바람직한 실시예에 기초하여 작성한 첨부도면에 따라 더욱 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings made on the basis of preferred embodiments.

본 발명의 시스템은 클러치 스위치(C), 릴레이(B), 기어스위치(A) 및 소프트웨어 로직 ECM(ELECTRONIC CONTROL MODULE)으로 구성하되, 상기 클러치 스위치(C)는 페달 마운트 어셈블리의 클러치 페달쪽에 설치하여 핀의 일측단자(7)는 릴레이 단자(4)와 연결하고 타측 단자(8)는 접지시킨다.The system of the present invention comprises a clutch switch (C), a relay (B), a gear switch (A) and software logic ECM (ELECTRONIC CONTROL MODULE), the clutch switch (C) is installed on the clutch pedal side of the pedal mount assembly One terminal 7 of the pin is connected to the relay terminal 4 and the other terminal 8 is grounded.

릴레이박스의 릴레이(B)의 단자(1)는 단자(10)(ECMPIN-OUT)와, 단자(2)는 기어스위치(A)의 단자(5)와 단자(3)은 이그니션(B+)와 각각 연결한다.Terminal 1 of relay B of the relay box is terminal 10 (ECMPIN-OUT), terminal 2 is terminal 5 of gear switch A and terminal 3 is ignition B + Connect to and respectively.

상기 기어스위치(A)는 기어 시프트레버 축에 설치하여 단자(5) 반대측의 단자(6)는 접지시키고, 소프트웨어는 ECM내의 EPROM(I. C)에 프로그래밍 한다.The gear switch A is mounted on the gear shift lever shaft, the terminal 6 on the opposite side of the terminal 5 is grounded, and the software is programmed in the EPROM (I. C) in the ECM.

그리고, ECM에는 공지의 차량속도센서(VSS), 냉각수온도센서(CTS), 이그니션 코일(G)을 접속하여 이들로부터 나오는 시그날을 받도록 구성한 것이다.In addition, a known vehicle speed sensor (VSS), a coolant temperature sensor (CTS), and an ignition coil (G) are connected to the ECM to receive signals from them.

이와 같이 구성된 본 발명의 자동차 출발초기 감지제어장치는 처음 출발(후진포함)을 위해서 클러치스위치(C)는 "ON"상태로 릴레이(B)는 "OFF"상태로 하여 클러치 페달을 밟은 상태에서 기어를 넣는다.In the vehicle starting initial detection control device of the present invention configured as described above, the clutch switch (C) is in the "ON" state and the relay (B) is in the "OFF" state for the first start (including reverse). Put it.

다음으로, 클러치스위치(C)와 기어스위치(A)의 "ON"상태에서 클러치 페달을 서서히 뗀다.Next, the clutch pedal is gradually released in the " ON " state of the clutch switch C and the gear switch A. FIG.

여기서, 클러치 스위치(C)는 "OFF", 릴레이(B)가 "ON"일때 클러치 페달의 총 스트로크는 140-147MM로, 페달을 완전히 밟은 상태에서 20MM까지 떼었을 ㄹ때 클러치 스위치(C)는 "ON"상태이고, 20MM 이후부터 클러치 페달을 완전히 놓을때까지 클러치 스위치(C)는 "OFF"상태이다.Here, when the clutch switch C is "OFF" and the relay B is "ON", the total stroke of the clutch pedal is 140-147MM, and when the pedal is fully depressed, the clutch switch C is released when it is 20MM. In the "ON" state, the clutch switch C is in the "OFF" state after 20MM until the clutch pedal is completely released.

따라서, 실제로 클러치 스위치(C) 신호가 들어가는 것은 스트로크가 20MM이후 부터가 된다.Therefore, the actual input of the clutch switch C signal comes after 20 mm in stroke.

그리고 클러치 스위치(C)에 신호가 입력되면 ECM에서 이 신호를 받아 연료 및 에어를 증가시킨다.When a signal is input to the clutch switch C, the ECM receives the signal to increase fuel and air.

본 발명에 의한 후로우챠트인 제 2 도를 보면, 클러치 시그날이 아닐 경우에는 엔진 RPM 저하가 700RPM 이상이 있을 경우 보상 에어프라그 및 보상 연료 프라그는 "0"으로 세팅되면서 에어 및 연료 보상은 일체되지 않고, 이때 에어 및 연료가 보상되어진 상태라면 곧바로 보상을 중지하여 엔진 RPM 저하가 700RPM 이하에 있을 경우에 에어 보상으로 토오크 저하를 방지한다.Referring to FIG. 2 of the flow chart according to the present invention, when the engine RPM is lower than 700 RPM when the clutch signal is not the compensation air prag and the compensation fuel prag are set to "0", air and fuel compensation are not integrated. In this case, if the air and fuel are compensated, the compensation is immediately stopped to prevent the torque decrease by the air compensation when the engine RPM is lower than 700 RPM.

클러치 시그날이 들어오고 냉각수 온도가 20℃ 이상일 경우, 그리고 차량 속도가 6KPH 이하일 경우에는 에어 및 연료가 보상된다. 클러치 시그날에 의해 보상되었던 차량 속도가 6KPH 이상일 때에는 보상되었던 에어는 1스텝씩 감소하고, 연료 보상은 해제된다.When the clutch signal comes in and the coolant temperature is above 20 ° C and the vehicle speed is below 6KPH, air and fuel are compensated. When the vehicle speed compensated by the clutch signal is 6 KPH or more, the compensated air decreases by one step, and fuel compensation is released.

그러므로, 본 발명은 수동 차량이면서 배기량이 낮은(1500CC이하) 어느 차종에든 적용할 수 있고 자동차 초기 출발시 차량에 전달되는 을컥거리는 진동감을 배제하고 차량 가속 성능에도 효과가 있는 것이다.Therefore, the present invention can be applied to any vehicle that is a manual vehicle and has a low displacement (1500CC or less), and has an effect on vehicle acceleration performance while excluding a sensation of vibration transmitted to the vehicle at the initial start of the vehicle.
