Abstract

PURPOSE: A shock damping method increases engine rpm by the amount needed according to the current rpm and car speed to damp shock on switching to lower speed by a simple nob switch operation and reduces time needed for gearshift. CONSTITUTION: A clutch switch(5) is fixed on a clutch pedal part. A TGS(Transmission Gear Shift) lever nob low speed shifting switch(6) is installed. The signals from the switches(5, 6) are connected to an and gate and inputted to an ECU(engine control unit, 8). The ECU(8) adjusts ignition timing and fuel amount set up in a ROM therein to increase the engine rpm as much as needed if the gear is shifted to lower speed.

본 발명은 저속 기어로 전환시 충격 완화 방법에 관한 것으로서, 더욱 상세하게는, 클러치 페달부에 클러치 스위치를 부착해서 기어 전환시에 충격을 줄이는 방법에 관한 것이다.The present invention relates to a method for mitigating shock when switching to a low speed gear, and more particularly, to a method for reducing shock when switching a gear by attaching a clutch switch to a clutch pedal part.

제1도는 평상 저속 기어 전환시 충격을 엔진 RPM과 시간의 그래프로 나타낸 도면이고, 제2도는 더블 클러치 조작시 충격을 엔진 RPM과 시간의 그래프로 나타낸 도면이다.FIG. 1 is a diagram showing a graph of the engine RPM and the time of impact at the time of the normal low gear switching, and FIG. 2 is a diagram showing a graph of the engine RPM and the time of the shock when operating the double clutch.

첫째 제1도에 도시한 바와 같이, 종래의 저속 기어로의 변환은 운행중 클러치를 밟고(1) 저속으로 기어를 변환한 다음 클러치를 연결(2)하면서 가속 페달을 밟는 방법을 사용하고, 두번째 제2도에 도시한 바와 같이 클러치를 끊고(3) 기어를 뺀 다음, 그 상태에서 클러치를 잇고 다시한번 클러치를 끊고(4) 기어를 넣는 방법, 즉 더불 클러치 조작 방법을 사용하고 있다.First, as shown in FIG. 1, the conventional shift to a low speed gear uses a method of stepping on the clutch while driving (1), shifting the gear to a low speed, and then pressing the accelerator pedal while connecting the clutch (2). As shown in Fig. 2, the clutch is disconnected (3), the gear is removed, the clutch is connected in that state, the clutch is disconnected again (4) and the gear is inserted, that is, the clutch operation method is used.

그러나 이러한 종래의 저속 기어로의 변환 방법중 첫번째 방법은 클러치를 뗄 때 운전자에게 충격을 준다는 문제점이 있고, 두번째 방법은 클러치를 두번이나 밟아야 하는등 운전자에게 불편을 준다는 문제점을 가지고 있다.However, the first method of converting the conventional low speed gear has a problem in that the driver is shocked when the clutch is released, and the second method has a problem in that it is inconvenient for the driver to step on the clutch twice.

본 발명의 목적은 간단한 스위치 조작으로 상기한 문제점 들을 해결하는데에 목적이 있다.An object of the present invention is to solve the above problems with a simple switch operation.

이러한 목적을 달성하기 위한 본 발명에 따른 저속 기어로의 변환시 충격 완화 방안은 클러치 페달부에 클러치 스위치를 부착하고 TGS(transmission gear shift) 레버 노브 저속 변환 스위치를 부착하는 것을 포함하고 있다.In order to achieve the above object, a shock mitigation method for converting to a low speed gear according to the present invention includes attaching a clutch switch to a clutch pedal part and attaching a transmission gear shift (TGS) lever knob low speed change switch.

그러면, 첨부한 도면을 참고로 하여 본 발명에 따른 수동 변속 차량에서 저속 기어로 전환시 충격 완화 방법의 한 실시예를 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있을 정도로 상세히 설명한다.Then, an embodiment of the shock mitigation method when switching to a low gear in a manual transmission vehicle according to the present invention with reference to the accompanying drawings to the extent that it can be easily carried out by those of ordinary skill in the art to which the present invention pertains. It explains in detail.

본 발명에 따른 이러한 저속 기어로 변환시 충격 완화 방법은 클러치 페달부에 클러치 스위치(5)를 부착하고 TGS 레버 노브 저속 변환 스위치(6)를 부착하여 이 두신호를 엔드 게이트(9)로 연결해 ECU(engine control unit)(8)에 입력시킨다.According to the present invention, the shock mitigation method when converting into a low speed gear includes a clutch switch 5 attached to a clutch pedal part and a TGS lever knob low speed change switch 6 to connect these two signals to the end gate 9 so that the ECU ( engine control unit) (8).

ECU(8)는 이러한 신호가 입력되면 엔진 RPM과 차의 속력에 의해서 ECU(8)내에 있는 ROM에 설정되어 있는 값으로 점화 시기와 연료량을 조절하여 엔진 RPM을 요구되는 양만큼 상승시킨다.When such a signal is input, the ECU 8 raises the engine RPM by the required amount by adjusting the ignition timing and the fuel amount to the value set in the ROM in the ECU 8 by the engine RPM and the speed of the car.

따라서 본 발명에 따른 수동 변속 차량에서 저속 기어로 전환시 충격 완화 방법은 운전자의 간단한 노브 스위치 조작에 의해 저속 변환시 현재의 RPM과 차속에 따라 요구되는 양만큼 엔진 RPM을 상승시켜 충격을 완화시키며 변속 시간 단축등의 효과를 올릴 수 있고, 특히 더블 클러치 조작은 단지 엔진 RPM을 약간 상승시키는 기능밖에 못하나 이 방식은 엔진 RPM을 저속 변환후의 설정값까지 올릴 수 있으므로 그 효과가 크다.Therefore, in the manual transmission vehicle according to the present invention, the shock mitigation method when switching to the low speed gear increases the engine RPM by the amount required according to the current RPM and the vehicle speed at low speed by a simple knob switch operation of the driver, thereby alleviating the shock and shifting time. In particular, the double clutch operation can only increase the engine RPM slightly, but this method can increase the engine RPM to the set value after the low speed conversion.
