Abstract

본 발명의 목적은 우천시 도로를 주행할 때 노면과 타이어의 사이에서 일어나는 수막현상에 의해 차량이 미끄러져 발생하는 사고를 저감하기 위한 자동차의 안전 주행 제어장치 및 그 제어방법을 제공하는데 있다.It is an object of the present invention to provide a safety driving control apparatus for a vehicle and a control method thereof for reducing an accident caused by a vehicle slipping due to a water film phenomenon occurring between a road surface and a tire when driving on a road in rainy weather.

이를 실현하기 위한 본 발명은 자동차의 주행속도를 감지하는 차속센서와, 쓰로틀 바디의 쓰로틀 밸브의 개도각을 감지하는 쓰로틀 포지션 센서와, 상기 양 센서로부터 전기적인 신호로 인가된 구동휠의 회전속도에 대해 쓰로틀 밸브의 개도각이 작거나 같음을 비교 판단하는 전자제어장치와, 이 전자제어장치가 비교 판단한 제어값에 의해 감속주행이 이루어지게 실린더에 공급되는 연료를 차단하도록 연료공급관에 설치된 솔레노이드 밸브를 포함하여 이루어지는 자동차의 안전주행 제어장치를 특징으로 한다.The present invention for realizing this, the vehicle speed sensor for detecting the driving speed of the vehicle, the throttle position sensor for detecting the opening angle of the throttle valve of the throttle body, and the rotational speed of the drive wheel applied as an electrical signal from both sensors The solenoid valve installed in the fuel supply pipe to cut off the fuel supplied to the cylinder so that the decelerating run is made by the control value determined by the electronic controller. It is characterized by a safety driving control device for a vehicle made.

상기 본 발명의 구성에 따른 제어방법은 자동차가 도로를 주행하는 단계와; 주행중일 때 차속 센서부에 의해 현재의 차속이 감지되는 단계와; 엔진의 쓰로틀 바디의 쓰로틀 밸브 개도각이 쓰로틀 포지션 센서에 의해 감지되는 단계와; 차속 센서부와 쓰로틀 포지션 센서에 의해 감지된 전기적인 신호의 데이타를 비교 판단하여 구동휠의 회전속도에 대해 쓰로틀 밸브의 개도각이 작거나 같음이 "아니오"이면 처음의 차속 감지단계로 진행하고, "예"이면 다음으로 진행하는 단계와; 쓰로틀 밸브의 개도각이 작거나 같음이 "예"이면 연료 공급관이 차단되도록 솔레노이드 밸브에 인가된 전원을 차단시키는 단계와; 연료가 솔레노이드 밸브의 차단에 의해 실린더에 일시적으로 공급되지 않는 단계와; 실린더에 연료가 공급되지 않음으로서 자동차의 속도가 감속되어 주행하는 단계로 이루어지는 자동차의 안전 주행 제어장치 및 그 제어방법을 특징으로 한다.The control method according to the configuration of the present invention includes the steps of driving a vehicle on the road; Detecting a current vehicle speed by the vehicle speed sensor unit while driving; Detecting the throttle valve opening angle of the throttle body of the engine by the throttle position sensor; Compare and judge the electric signal data detected by the vehicle speed sensor unit and the throttle position sensor, and if the opening angle of the throttle valve is less than or equal to the rotational speed of the drive wheel, proceed to the first vehicle speed detection step, If yes, go to the next step; If the opening angle of the throttle valve is less than or equal to "Yes", shutting off the power applied to the solenoid valve to shut off the fuel supply pipe; The fuel is temporarily not supplied to the cylinder by blocking the solenoid valve; It is characterized by a safety driving control device and a control method of a vehicle comprising the step of driving the vehicle speed is reduced because the fuel is not supplied to the cylinder.
