그러나, 상기한 바와 같은 종래의 클러치 조작기구는 1단이나 후진 등에서 변속기 기어 체결 후 클러치 패달을 서서히 놓아 반클러치 상태를 유지해야 되지만, 운전자의 조작 미숙 특히, 초보 운전자의 경우 반클러치 조작이 어렵기 때문에 시동 꺼짐현상이 발생되어 교통 사고의 위험을 초래하게 되는 문제점이 있다.However, in the conventional clutch operation mechanism as described above, the clutch pedal must be gradually released by the transmission of the transmission gear at the first stage or the reverse, but the clutch clutch must be kept in a semi-clutch state. Therefore, there is a problem that the start-up phenomenon occurs that causes the risk of traffic accidents.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 1단 출발이나 후진 주행시 릴리이스 실린더로 공급되는 유압을 조절하여 클러치의 작동 속도를 적절하게 조절함으로써, 운전자의 조작 미숙으로 인한 시동 꺼짐현상을 방지할 수 있는 차량용 시동 꺼짐 방지장치를 제공하는 데 있다.The present invention has been made to solve the above problems, the object of the present invention is to adjust the operating speed of the clutch appropriately by adjusting the hydraulic pressure supplied to the release cylinder during the first stage start or reverse driving, to the driver's immature operation It is to provide a vehicle starting off prevention device that can prevent the starting off phenomenon caused by.

이하, 첨부된 도면을 참조하여 본 발명의 일실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 시동 꺼짐 방지장치가 설치되는 수동변속기의 변속조작기구를 나타낸 구성도이다.2 is a block diagram showing a shift operation mechanism of a manual transmission in which the start-off prevention device according to the present invention is installed.

본 발명의 일 실시예에 따른 변속조작기구는 클러치 패달(2)의 답력에 의해 유압을 발생시키는 마스터 실린더(4)와, 이 마스터 실린더(4)와 유압라인(6)으로 연결되어 마스터 실린더(4)에서 발생된 유압이 공급되는 릴리이스 실린더(8)와, 상기 릴리이스 실린더(8)로 공급되는 유압에 의해 직선 이동되는 푸시로드(10)와, 상기 푸시로드(10)의 직선 이동에 따라 릴리이스 베어링(12)을 밀어주어 클러치(20)를 작동시키는 릴리이스 포크(14)와, 상기 유압라인(6)의 일측에 설치되어 1단 출발이나 후진시 마스터 실린더(4)에서 릴리이스 실린더(8)로 공급되는 유압을 조절하여 급격한 클러치 작동에 따른 시동 꺼짐 현상을 방지할 수 있는 시동 꺼짐 방지장치로 구성된다.According to an embodiment of the present invention, the shift operating mechanism includes a master cylinder 4 for generating hydraulic pressure by the pedal force of the clutch pedal 2, and a master cylinder 4 connected to the master cylinder 4 and the hydraulic line 6. 4) the release cylinder 8 to which the hydraulic pressure generated in 4) is supplied, the push rod 10 linearly moved by the hydraulic pressure supplied to the release cylinder 8, and the linear movement of the push rod 10. According to the release fork 14 to push the release bearing 12 to operate the clutch 20, and is installed on one side of the hydraulic line 6, the release from the master cylinder (4) at the first stage start or reverse By controlling the hydraulic pressure supplied to the cylinder (8) is composed of a starting off prevention device that can prevent the starting off phenomenon due to the sudden clutch operation.

상기 시동 꺼짐 방지장치는 상기 유압라인(6)에 설치되어 마스터 실린더(4)에서 릴리이스 실린더(8)로 공급되는 유압을 조절하는 유압 조절밸브(24)와, 현재 차량의 상태 즉, 현재 차량이 1단 출발이나 후진인 것으로 판단되면, 상기 유압 조절밸브(24)를 온(ON)시키고 작동시키고 엔진 RPM이 충분히 상승한 것으로 판단되면 유압 조절밸브(24)를 오프(OFF) 시키는 제어수단으로 구성된다.The start-off prevention device is installed in the hydraulic line (6) and the hydraulic control valve 24 for adjusting the hydraulic pressure supplied from the master cylinder (4) to the release cylinder (8), the state of the current vehicle, that is, the current vehicle If it is determined that the first stage of the start or reverse, the hydraulic control valve 24 is turned on (ON) and operated, and if it is determined that the engine RPM is sufficiently raised, the control means for turning off the hydraulic control valve (24) do.

상기 유압 조절밸브(24)는 전원이 온(ON)되면 유압라인을 일정 폭만큼 막아 통과하는 오일량을 조절하여 릴리이스 실린더(8)에 작용하는 유압을 조절하는 솔레노이드 밸브로 이루어진다.The hydraulic control valve 24 is composed of a solenoid valve for controlling the hydraulic pressure acting on the release cylinder (8) by adjusting the amount of oil passing through the hydraulic line by a certain width when the power is turned on (ON).

여기에서, 제어수단은 도 3에 도시된 바와 같이, 클러치 패달(2)의 일측에 설치되어 클러치 패달(2)을 밟으면 온(ON)되는 클러치 스위치(26)와, 현재 차량의차속을 감지하는 차속센서(28)와, 변속레버(2)의 일측에 설치되어 현재 변속단을 검출하는 변속기어 위치센서(30)와, 스로틀 밸브의 일측에 설치되어 스로틀 밸브의 작동위치를 검출하는 스로틀 포지션센서(34)와, 상기 각 센서류의 신호에 따라 상기 유압 조절밸브(24)를 온/오프시키는 ECU(전자제어유닛)(32)으로 구성된다.Here, as shown in Figure 3, the control means is installed on one side of the clutch pedal 2, the clutch switch 26 that is turned on (ON) when pressing the clutch pedal 2, and detects the vehicle speed of the current vehicle A vehicle speed sensor 28, a shift gear position sensor 30 installed at one side of the shift lever 2 to detect a current shift stage, and a throttle position sensor installed at one side of the throttle valve to detect an operating position of the throttle valve. 34 and an ECU (electronic control unit) 32 for turning on / off the hydraulic control valve 24 in accordance with signals of the sensors.

이와 같이 이루어진 본 발명에 따른 차량용 시동 꺼짐 방지장치의 작용을 다음에서 설명한다.The operation of the vehicle start-off prevention device according to the present invention made as described above will be described below.

먼저, 차속센서(28)로부터 전달되는 신호를 인가받아 현재 차속이 거의 정차상태에 가까운 것으로 판단되고, 변속기어 위치센서(30)로부터 전달되는 신호를 인가받아 현재 변속단이 1단 또는 후진인 것으로 판단되고, 클러치 스위치(26)로 인가되는 신호를 인가받아 클러치 패달(2)이 작동상태인 것으로 판단되면, ECU(32)는 현재 차량이 정차상태에서 출발상태인 것으로 판단하여 유압 조절밸브(24)를 온(ON)시킨다.First, it is determined that the current vehicle speed is almost close to the stop state by receiving the signal transmitted from the vehicle speed sensor 28, and the current transmission stage is one step or the reverse when the signal transmitted from the transmission gear position sensor 30 is applied. If it is determined that the clutch pedal 2 is in operation by receiving a signal applied to the clutch switch 26, the ECU 32 determines that the current vehicle is in the starting state from the stopped state and the hydraulic control valve 24 ON).

그러면, 상기 유압 조절밸브(24)는 유압라인(6)을 일정 정도만큼 차단하여 마스터 실린더(4)에서 발생된 유압이 릴리이스 실린더(8)로 천천히 공급되도록 하여 클러치(20)가 천천히 작동되어 엔진의 시동이 꺼지는 현상을 방지한다.Then, the hydraulic control valve 24 blocks the hydraulic line 6 to a certain degree so that the hydraulic pressure generated in the master cylinder 4 is supplied slowly to the release cylinder 8 so that the clutch 20 is operated slowly. This prevents the engine from turning off.

그리고, 스로틀 포지션 센서(34)로부터 인가되는 신호에 따라 운전자가 가속 패달(2)을 충분히 밟은 상태이고 엔진의 RPM이 충분히 상승된 것으로 판단되면 유압 조절밸브(24)를 오프(OFF)시켜 릴리이스 실린더(8)로 공급된 유압이 즉시 배출될 수 있도록 한다.In response to a signal applied from the throttle position sensor 34, when the driver has sufficiently stepped on the acceleration pedal 2 and the RPM of the engine is sufficiently raised, the hydraulic control valve 24 is turned off to release the release. The hydraulic pressure supplied to the cylinder 8 can be immediately discharged.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 차량용 시동 꺼짐 방지장치는 마스터 실린더와 릴리이스 실린더 사이의 유압 라인에 솔레노이드 밸브를 설치하여, 차량이 1속 또는 후진시 운전자가 클러치 패달에서 발을 떼는 과정에서 솔레노이드 밸브를 작동시켜 릴리이스 실린더로 공급되는 유압을 제어하여 클러치의 급격한 작동을 방지하여, 수동 변속기 차량의 출발시 발생되는 시동 꺼짐 현상으로 인한 교통 사고를 방지할 수 있다.Therefore, the start-off protection device for a vehicle according to the present invention constructed and operated as described above may install a solenoid valve in a hydraulic line between a master cylinder and a release cylinder, so that the driver may take his foot from the clutch pedal when the vehicle is driven at a speed or reverse. By operating the solenoid valve in the release process to control the hydraulic pressure supplied to the release cylinder to prevent the sudden operation of the clutch, it is possible to prevent traffic accidents due to the start-off phenomenon that occurs when the manual transmission vehicle starts.
