이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 수동 변속 차량의 자동 출발 방법이 도시된 구성도이다.2 is a block diagram showing an automatic start method of a manual transmission vehicle according to the present invention.

본 발명의 자동 출발방법을 실현하기 위한 장치의 구성은 통상의 차속 센서등을 통해 차량의 주행 상태나 정지 상태를 감지하여 제어부(ECU)(50)에 입력하는 차량정지 감지수단(51)과, 변속 레버의 작동 상태를 감지하여 기어 1단 변속 상태를 감지하여 상기 제어부(50)에 입력하는 1단변속 감지수단(53)과, 클러치 페달(60)의 작동 상태를 감지하여 제어부(50)에 입력하는 페달 작동 감지수단(55)이 구성된다.The configuration of the apparatus for realizing the automatic starting method of the present invention comprises a vehicle stop detecting means 51 for detecting a driving state or a stop state of a vehicle through a normal vehicle speed sensor or the like and inputting it to the control unit (ECU) 50; Detects the operation state of the shift lever to detect the gear 1 gear shift state and inputs the control unit 50 to the control unit 50, and detects the operation state of the clutch pedal 60 to the control unit 50. Pedal operation detecting means 55 for input is configured.

그리고, 상기 제어부(50)로부터 제어신호를 받아 가속 페달(65)을 자동으로 작동할 수 있도록 액츄에이터(70)가 구비된다.In addition, an actuator 70 is provided to automatically operate the accelerator pedal 65 by receiving a control signal from the controller 50.

이와 같은 장치를 통한 본 발명의 자동 출발 방법은 클러치 페달(60)을 밟아 엔진(40)에서 변속기(47)로 전달되는 회전 동력이 차단되는 상태를 페달작동 감지수단(55)을 통해 감지함과 동시에 상기 차량정지 감지수단(51)을 통해 차량이 정지되어 있는 상태를 감지하는 차량정지 감지단계와;The automatic starting method of the present invention through such a device detects a state in which the rotational power transmitted from the engine 40 to the transmission 47 is blocked by stepping on the clutch pedal 60 through the pedal operation detecting means 55. A vehicle stop detection step of detecting a state in which the vehicle is stopped through the vehicle stop detection means (51);

상기 차량정지 감지단계에서 차량의 출발을 위해 1단 기어 변속이 이루어질 경우 1단변속 감지수단(53)을 통해 1단 변속 상태를 감지하는 1단변속 감지단계와;A first gear shift detection step of detecting a first gear shift state through the first gear shift sensing means 53 when the first gear shift is made for the start of the vehicle in the vehicle stop sensing step;

상기 페달작동 감지수단(55)을 통해 1단 기어 변속이 실시된 상태에서 차량의 출발을 위해 엔진(40)에서 변속기(47) 측으로 동력이 전달되도록 운전자가 클러치 페달(60)에서 발을 떼는 상태를 감지하는 출발의지 감지단계와;The driver disengages from the clutch pedal 60 so that power is transmitted from the engine 40 to the transmission 47 side for the start of the vehicle in the state where the first gear shift is performed through the pedal operation detecting means 55. Detect the starting will detect the step;

차량 정지상태에서 변속기(47)측에 동력이 전달되면 엔진의 회전 속도가 일정 속도 이상이 되도록 액츄에이터(70)를 통해 가속 페달(65)을 자동으로 작동함으로써 스로틀(43) 개도량을 변화시키는 자동 출발단계로 이루어진다.When power is transmitted to the transmission 47 side in the vehicle stop state, the automatic operation of the throttle 43 opening amount is changed by automatically operating the accelerator pedal 65 through the actuator 70 so that the rotation speed of the engine becomes higher than a predetermined speed. It is a starting stage.

상기 자동출발단계에서 엔진의 회전수는 2000rpm 정도가 되도록 설정하고,운전자가 가속 페달(65)을 밟았을 경우에는 가속 페달(65)을 밟은 양만큼 스로틀(43) 개도량이 결정되도록 한다.In the automatic starting step, the engine speed is set to about 2000 rpm, and when the driver presses the accelerator pedal 65, the amount of opening of the throttle 43 is determined by the amount of stepping on the accelerator pedal 65.

즉, 차량의 출발을 위해 운전자가 클러치 페달(60)에서 발을 떨 경우, 액츄에이터(70)가 자동으로 운전자가 가속 페달(65)을 밟은 것과 같이 가속 페달(65)을 작동시키게 되나, 이때 운전자가 가속 페달(65)을 밟을 경우에는 운전자의 가속 페달(65) 밟음량 만큼 작동되도록 액츄에이터(70)도 작동된다.That is, when the driver steps on the clutch pedal 60 to start the vehicle, the actuator 70 automatically operates the accelerator pedal 65 as if the driver stepped on the accelerator pedal 65, but the driver When the user presses the accelerator pedal 65, the actuator 70 is also operated to operate as much as the driver's accelerator pedal 65 stepped.

여기서, 상기 액츄에이터(70)에 의한 가속 페달(65)의 작동은 운전자가 클러치 페달(60)을 떼게 되는 과정에서 자연스럽게 클러치(45)가 연결됨과 동시에 엔진 회전수(rpm)가 상승하도록 설정되어야 한다.Here, the operation of the accelerator pedal 65 by the actuator 70 should be set such that the engine speed (rpm) is increased at the same time the clutch 45 is naturally connected while the driver releases the clutch pedal 60. .

그리고, 출발 후 다시 운전자가 클러치 페달(60)을 다시 밟고 클러치 페달(60)에서 발을 떨 경우나 다른 변속단으로 변경할 경우에는 상기 액츄에이터(70)는 작동되지 않는다.In addition, the actuator 70 does not operate when the driver steps on the clutch pedal 60 again and starts to step on the clutch pedal 60 or changes to another shift stage.

즉, 차량이 정지됨과 아울러 클러치가 이격되어 동력전달이 차단된 상태에서 1단 기어변속과 함께 클러치 페달을 밟지 않을 때 1회에 한하여 제어부(50)의 신호를 통해 상기 액츄에이터(70)가 가속페달(65)을 작동할 수 있도록 이루어진다.That is, when the vehicle is stopped and the clutch is spaced apart and power transmission is blocked, the actuator 70 is accelerated through the signal of the controller 50 only once when the clutch pedal is not pressed together with the first gear shift. 65 is made to operate.

따라서, 상기와 같이 구성되고 작용되는 본 발명의 수동 변속 차량의 자동 출발 방법은 차량 출발시 클러치 페달을 떼는 과정에서 자동으로 가속 페달이 작동되도록 하여 운전자의 편의성을 향상시킴과 아울러 초보 운전자가 시동이 꺼뜨릴 수 있는 상황을 방지할 수 있는 이점이 있다.Therefore, the automatic starting method of the manual transmission vehicle of the present invention constructed and operated as described above enables the accelerator pedal to be automatically operated in the process of releasing the clutch pedal when the vehicle starts, thereby improving the driver's convenience and starting the novice driver. There is an advantage to avoid situations that can be extinguished.
