In particular, when a gear shift to a first gear is detected and a change in the accelerator position is detected, the opening degree of the throttle valve is determined regardless of the amount of change in the position of the accelerator for a predetermined time. The present invention relates to a vehicle starting prevention control method for gradually adjusting to prevent the starting of the vehicle.

일반적으로, 액셀레이터는 쓰로틀 밸브에 연결되어 쓰로틀 밸브의 개방 정도를 조정하므로써 가솔린 엔진에서는 혼합기의 흡입량을, 디젤 엔진에서는 연료의 분사량을 조절하여 엔진의 회전수를 조정한다.In general, the accelerator is connected to the throttle valve to adjust the degree of opening of the throttle valve to adjust the engine speed by adjusting the intake amount of the mixer in the gasoline engine and the injection amount of the fuel in the diesel engine.

그러나, 초보 운전자의 경우에는 액셀레이터에 대한 감각이 부족하여 자동차 출발시 액셀레이터를 너무 많이 밟아 자동차를 급출발시켜 앞차를 추돌하는 경우가 있다.However, in the case of a novice driver, there is a lack of a sense of the accelerator, and when the vehicle starts, the driver may step on the accelerator too much and suddenly start the vehicle to crash the front vehicle.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 자동차 출발시 1단 기어상태에서 출발함에 따라 기어의 1단기어로의 변속을 검출하고 액셀레이터의 위치변화를 검출하면 소정의 시간동안 액셀레이터의 위치 변화량과 무관하게 쓰로틀 밸브의 개방정도를 점차적으로 개폐조정하여 자동차의 급출발 방지하는 자동차 급출발 방지 제어방법을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, and when the vehicle starts from the first gear state when the vehicle starts, detecting the shift of the gear to the first gear and detecting the change of the position of the accelerator for a predetermined time It is an object of the present invention to provide a control method for preventing the starting of the vehicle by preventing the starting of the vehicle by gradually opening and closing the opening degree of the throttle valve irrespective of the position change amount.

상기와 같은 목적을 달성하기 위하여 본 발명은, 기어의 변속상태를 검출하는 기어변속 검출센서와, 액셀레이터 위치의 변화를 검출하는 액셀레이터 위치센서와, 상기 기어변속 검출센서와 액셀레이터 위치센서의 출력신호에 따라 쓰로틀 밸브의 개방정도를 조정하기 위한 제어신호를 출력하는 제어부를 구비하는 자동차에 적용되는 자동차 급출발 방지 제어방법에 있어서, 상기 기어변속 검출센서가 기어의 변속상태를 검출하는 제1단계와, 상기 제1단계에서 검출된 기어변속이 1단기어로의 변속인지 판단하는 제2단계와, 상기 제2단계에서 기어변속이 1단기어로의 변속이면 액셀레이터 위치센서가 액셀레이터 위치의 변화유무를 판단하는 제3단계와, 상기 제2단계에서 액셀레이터 위치에 변화가 있으면 소정의 시간동안 액셀레이터의 위치 변화량과 무관하게 쓰로틀 밸브의 개방정도를 점차적으로 조정하는 제4단계를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a gear shift detection sensor for detecting a shift state of a gear, an accelerator position sensor for detecting a change in an accelerator position, and an output signal of the gear shift detection sensor and an accelerator position sensor. In the vehicle sudden start prevention control method applied to a vehicle having a control unit for outputting a control signal for adjusting the opening degree of the throttle valve according to the first step, wherein the gear shift detection sensor detects a gear shift state; A second step of determining whether the gear shift detected in the first step is shifting to the first gear, and a third of the accelerator position sensor determining whether the accelerator position is changed if the gear shift is shifting to the first gear in the second step. And if there is a change in the accelerator position in the second step, the position change amount of the accelerator for a predetermined time and And a fourth step of gradually adjusting the opening degree of the throttle valve regardless.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명이 적용되는 자동차의 급출발을 방지하기 위한 제어장치의 구성을 나타낸 것으로, 기어의 변속상태를 검출하는 기어변속 검출센서(10)와 액셀레이터 위치의 변화를 검출하는 액셀레이터 위치센서(20)가 제공되어 있다.1 shows a configuration of a control device for preventing sudden start and departure of a vehicle to which the present invention is applied, and a gear shift detection sensor 10 for detecting a shift state of a gear and an accelerator position sensor 20 for detecting a change in an accelerator position. ) Is provided.

제어부(30)는 상기 기어변속 검출센서(10)와 액셀레이터 위치센서(20)의 출력신호에 따라 쓰로틀 밸브(40)의 개방정도를 조정하기 위한 제어신호를 출력한다.The controller 30 outputs a control signal for adjusting the opening degree of the throttle valve 40 according to the output signals of the gear shift detection sensor 10 and the accelerator position sensor 20.

제2도는 본 발명에 따른 자동차 급출발 방지 제어방법의 제어 흐름을 나타낸 도면이다.2 is a view showing a control flow of the vehicle starting prevention control method according to the present invention.

먼저, 기어변속 감지센서(10)가 기어의 변속상태를 검출하여 제어부(30)에 알린다(101). 이에따라 제어부(30)는 기어가 1단기어로 변속되었는지 판단하고, 1단기어 이외의 상태, 예를들어 2, 3, 4, 및 5단기어로 기어변속 되었으면 액셀레이터 위치센서(20)에서 검출된 액셀레이터 위치 변화량에 따라 쓰로틀 밸브(40)의 개방정도를 조정한다(103,104).First, the gear shift detection sensor 10 detects the shift state of the gear and informs the controller 30 (101). Accordingly, the controller 30 determines whether the gear is shifted to the first gear, and if the gear is shifted to a gear other than the first gear, for example, 2, 3, 4, and 5 gears, the accelerator position detected by the accelerator position sensor 20 is determined. The opening degree of the throttle valve 40 is adjusted according to the amount of change (103, 104).

한편, 기어가 1단기어로 변속되었으면, 액셀레이터 위치센서(20)가 액셀레이터 위치의 변화유무를 판단한다(105). 액셀레이터 위치에 변화가 없으면 쓰로틀 밸브(40)의 개방정도를 현상태로 유지하고, 액셀레이터 위치에 변화가 있으면 소정의 시간동안, 예를들어 3∼5초 동안 액셀레이터의 위치 변화량과 무관하게 쓰로틀 밸브(40)의 개방정도를 점차적으로 조정하여 급출발을 제한한다.On the other hand, if the gear is shifted to the first gear, the accelerator position sensor 20 determines whether or not the accelerator position is changed (105). If there is no change in the accelerator position, the opening degree of the throttle valve 40 is maintained as it is, and if there is a change in the accelerator position, the throttle valve 40 is independent of the amount of change in the position of the accelerator for a predetermined time, for example, 3 to 5 seconds. The opening degree is limited gradually by adjusting the degree of opening.

상기와 같이 본 발명은, 1단기어로의 기어변속이 검출되고 액셀레이터의 위치변화가 검출되면 소정의 시간동안 쓰로틀 밸브의 개방정도를 액셀레이터의 위치 변화량과 무관하게 점차적으로 조정하여 자동차의 급출발을 방지할 뿐만 아니라 급출발에 따른 추돌사고를 방지하며 아울러 연료의 과다한 소비를 방지할 수 있다.As described above, the present invention, when the gear shift to the first gear is detected and the position change of the accelerator is detected, the opening degree of the throttle valve is gradually adjusted for the predetermined time irrespective of the position change amount of the accelerator to prevent the rapid starting of the vehicle. In addition, it is possible to prevent collisions caused by sudden start and to prevent excessive consumption of fuel.
