Abstract
Description
본 발명은 차량용 급출발 방지 장치 및 방법에 관한 것으로서, 특히 액셀 페달의 스트로크량을 검출하여 운전자의 액셀 페달 오조작에 의한 급출발시 차량을 정지시킬 수 있는 급출발 방지 장치 및 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus and method for preventing rapid start for vehicles, and more particularly, to an apparatus and method for preventing rapid start, which can stop a vehicle when a driver starts an accident due to an accelerator pedal misoperation by detecting an stroke amount of an accelerator pedal.
종래 기술에 있어서, 차량의 속도는 다음과 같이 제어된다.In the prior art, the speed of the vehicle is controlled as follows.
먼저, 운전자가 액셀 페달을 밟으면, 그에 따른 액셀 와이어의 장력에 의해 스로틀 밸브를 개폐함으로써 실린더로 흡입되는 혼합가스의 양을 조절하여 차량 속도의 가감을 제어한다.First, when the driver presses the accelerator pedal, by controlling the amount of the mixed gas sucked into the cylinder by opening and closing the throttle valve by the tension of the accelerator wire according to the control of the vehicle speed.
그러나, 이와 같은 종래 기술에서는 운전자의 부주의로 인한 액셀 페달의 급조작시 차량의 제어가 불가능하다.However, in such a prior art, it is impossible to control the vehicle during sudden operation of the accelerator pedal due to the carelessness of the driver.
예를 들면, 오토메틱 차량에 있어서, 운전자가 브레이크 페달을 클러치 페달로 그 오른편에 있는 액셀 페달을 브레이크 페달로 인식한 경우, 통상 차량을 출발시킬 때 브레이크 페달을 밟고 파킹 레버를 해제하므로 무의식중에 액셀 페달을 브레이크 페달로 오인하여 액셀 페달을 강하게 밟아 차량이 급출발하는 경우가 발생할 수 있다.For example, in an automatic vehicle, when the driver recognizes the brake pedal as a clutch pedal and the accelerator pedal on the right side as a brake pedal, the accelerator pedal is unconscious because the driver normally presses the brake pedal and releases the parking lever when starting the vehicle. May be mistaken for the brake pedal, and the vehicle may suddenly start by stepping hard on the accelerator pedal.
더욱이, 차량 전방에 사람 또는 사물이 있을 경우에는 대형 사고가 발생할 수도 있다.Moreover, when there are people or objects in front of the vehicle, a large accident may occur.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여, 페달 센서를 사용하여 급출발시 차량을 정지시킬 수 있는 급출발 방지 장치 및 방법을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a rapid start prevention device and method that can stop the vehicle at the time of sudden start using the pedal sensor.

상기 목적을 달성하기 위하여, 본 발명에 따른 급출발 방지 장치는 액셀 페달과, 상기 액셀 페달의 스트로크에 반응하여 센서 신호를 발생시키는 페달 센서와, 상기 센서 신호를 검출하여 액셀 페달의 스트로크가 소정 레벨 이상일 때 제어신호를 발생시키는 전자 제어 장치(ECU)와, 상기 전자 제어 장치의 제어 신호에 의해 연료 공급 라인의 연료 공급을 차단시키는 솔레노이드 밸브를 포함한다.In order to achieve the above object, the rapid start prevention device according to the present invention is an accelerator pedal, a pedal sensor for generating a sensor signal in response to the stroke of the accelerator pedal, and the stroke of the accelerator pedal by detecting the sensor signal is a predetermined level or more An electronic control unit (ECU) for generating a control signal at the time, and a solenoid valve for shutting off the fuel supply of the fuel supply line by the control signal of the electronic control device.
도 1에 나타낸 것과 같이, 액셀 페달(110)의 스트로크가 페달 센서(112)에 의해 감지되어 전압값을 출력하면, 그 값을 기초로 전자 제어 장치(120)가 솔레노이드 밸브(134)를 작동시켜 연료 탱크(130)로부터의 연료가 인젝터(142)에서 분사된다.As shown in FIG. 1, when the stroke of the accelerator pedal 110 is detected by the pedal sensor 112 and outputs a voltage value, the electronic controller 120 operates the solenoid valve 134 based on the value. Fuel from fuel tank 130 is injected at injector 142.
이하, 급출발 방지 방법에 관해 도 2를 참조하여 설명한다.Hereinafter, the sudden start prevention method will be described with reference to FIG. 2.
도 2는 본 발명의 바람직한 실시예에 따른 급출발 방지 방법의 흐름도이다.2 is a flowchart of a sudden start prevention method according to a preferred embodiment of the present invention.
먼저, 운전자가 페달(110)을 움직임으로써 페달 스트로크가 변화되면(S1), 페달 센서(112)내 가변 저항값의 변화에 따른 전압을 전자 제어 장치(120)로 전송한다(S2).First, when the pedal stroke is changed by the driver moving the pedal 110 (S1), the driver transmits a voltage according to the change of the variable resistance value in the pedal sensor 112 to the electronic control apparatus 120 (S2).
전송된 전압값을 전자 제어 장치(120)가 디지털 신호로 변환한 후, 표 1에 나타낸 것과 같은 테이블을 사용하여 페달 스트로크를 판단한다(S3).After the electronic control apparatus 120 converts the transmitted voltage value into a digital signal, the pedal stroke is determined using a table as shown in Table 1 (S3).
전압값이 단계적으로 변화하는 정상 페달 스트로크로 판단되면, 페달 스트로크에 해당하는 연료량을 연산하여 연료를 분사한다(S4). 이로 인해, 차량은 정상주행을 한다(S5).When it is determined that the normal pedal stroke in which the voltage value changes in stages, the fuel amount corresponding to the pedal stroke is calculated to inject fuel (S4). For this reason, the vehicle runs normally (S5).
그러나, 전압값이 급가속으로 인식되는, 전체 페달 스트로크의 7/8에 해당하는 0.74[㎷]보다 크면, 솔레노이드 밸브(134)에 연료 차단신호를 전송하여 엔진(1 40) 내부로 인입되는 연료가 차단됨으로써(S4'), 엔진이 정지하고 이에 따라 차량이 멈추게 된다(S5').However, if the voltage value is greater than 0.74 [kPa] corresponding to 7/8 of the entire pedal stroke, which is recognized as a rapid acceleration, the fuel drawn into the engine 1 40 by transmitting a fuel cutoff signal to the solenoid valve 134. Is blocked (S4 '), the engine stops and the vehicle is stopped accordingly (S5').
바람직하게, 스트로크량은 0,1,2, ... ,48,49,50 으로 구분된다.Preferably, the stroke amount is divided into 0, 1, 2, ..., 48, 49, 50.
따라서, 본 발명에 의해, 엔진(140) 시동 온(on) 상태에서 액셀 페달(110)의 조작이 급조작임을 센서(112)가 판단하고, 센서 신호에 따른 제어 신호를 전자 제어 장치(120)가 발생시켜 연료를 차단함으로써 급출발에 의한 인명 사고 등을 방지할 수 있다.Therefore, according to the present invention, the sensor 112 determines that the operation of the accelerator pedal 110 is suddenly operated in the engine 140 starting on state, and the electronic control apparatus 120 determines a control signal according to the sensor signal. It is possible to prevent accidents due to sudden start and death by generating fuel.
본 발명에 따르면, 페달 센서에 의해 운전자의 실수로 인한 급출발을 방지할 수 있다.According to the present invention, it is possible to prevent the starting and departure due to the driver's mistake by the pedal sensor.
본 발명이 바람직한 실시예를 참고하여 특별히 도시되고 설명되었지만, 본 발명의 정신과 범위를 벗어나지 않고서도 전술한 실시예의 형태와 상세에 있어 다른 변경이 이루어 질 수 있음을 이 기술 분야의 당업자는 이해할 수 있을 것이다.While the invention has been particularly shown and described with reference to preferred embodiments, it will be apparent to those skilled in the art that other changes may be made in form and detail of the above-described embodiments without departing from the spirit and scope of the invention. will be.
