본 발명은 차량 음주방지 시스템, 더 상세하게는 음주 상태에 따라 다단계의 운전제한요소를 가할 수 있는 차량 음주방지 시스템에 관한 것이다. The present invention relates to a vehicle anti-drinking system, and more particularly, to a vehicle anti-drinking system that can apply a multi-step driving restriction element according to the drinking state.

차량의 증가로 인하여 교통사고의 발생빈도가 증가하고 있다. 특히 음주운전에 의한 사고는 운전자의 죄책감이 없는 가벼운 인식으로 물적인 피해와 돌이킬 수 없는 인적 피해를 야기한다. As the number of vehicles increases, the frequency of traffic accidents is increasing. In particular, accidents caused by drunk driving result in physical damage and irreparable human damage due to the light recognition without the guilt of the driver.

한국특허공개 제2003-83943호에는 운전대 근처에 음주측정단을 설치하고 기준치를 초과하는 음주측정 데이타 값에는 자동차 시동을 제한함으로써 음주운전을 방지하는 기술이 개시되어 있다. 이러한 장치는 시동모터에 가는 전류를 차단하는 방법으로 달성할 수 있으므로 간단하기는 하나 음주운전 시 차량의 시동 제어에 주목적을 두고 있거나 이를 외부에 알리는 경고 장치에만 국한된다. 뿐만아니라 운전 자가 편법을, 예를 들면 제3자를, 동원하여 차량을 시동하고 운전하는 등 음주운전 방지 장치를 무력화하는 것에 대응하기 위해서는 복잡한 수단을 강구하여야 한다. 또한, 시동제한 설정치를 음주단속수준에 맞추면 그 이하의 경우 단속에 걸리지 않지만 음주를 하였기 때문에 그에 맞는 유연한 방지책이 필요하다. 시동제한 설정치를 아주 낮추면 운전에 크게 지장을 주지 않는 음주에도 시동이 걸리지 않으므로 운전자에게 많은 불편을 초래하는 문제점이 있다. Korean Patent Laid-Open Publication No. 2003-83943 discloses a technique for preventing drunk driving by installing a drunk measurement unit near a steering wheel and limiting the start of the car to a drunk measurement data value exceeding a reference value. Such a device can be achieved by cutting off the current to the starting motor, but it is simple, but is limited to a warning device which mainly aims at controlling the start of the vehicle during drunk driving or informs the outside. In addition, in order to cope with the driver's disabling of the drunk driving prevention device, for example, by using a third party to start and drive a vehicle, complicated measures must be taken. In addition, if the start limit is set to the drinking control level is lower than the regulation does not take, but because it was drunk, there is a need for a flexible prevention. If the start limit setting is very low, there is a problem that causes a lot of inconvenience to the driver because it does not start even if drinking does not significantly affect driving.

본 발명자는 다음 사항을 기술적 과제로 하여 본 발명을 완성하게 되었다.MEANS TO SOLVE THE PROBLEM This inventor completed this invention based on the following matters.

2). 시동제한 설정치 이하의 경우에는 운전자의 반응속도의 저하를 감안하여 운전자의 알콜 농도에 따라 차량의 최고속도를 제어한다.2). Below the limit value, the maximum speed of the vehicle is controlled according to the alcohol concentration of the driver in consideration of the decrease in the driver's reaction speed.

3). 차량 시동 중의 음주라든지, 운전 중의 혈중 알코홀 변화를 반영할 수 있도록 한다.
3). This can be used to reflect drinking alcohol during vehicle start-up or changes in blood alcohol during driving.

If the value is greater than or equal to the set value "off" the current opening and closing means of the starter motor and / or stops fuel supply by the fuel supply control means, and if the drinking measurement value is less than the set value, by setting the maximum speed of the car step by step fuel supply control means There is provided a vehicle anti-drinking system to regulate the fuel supply. Preferably, the control means stops the fuel supply by the fuel supply control means at the same time "off" the current opening and closing means of the starting motor when the drinking measurement value is more than the set value.

상기 음주측정수단은 백금촉매방식의 알코홀측정센서일 수 있다. 백금전극에 전달된 호흡 내의 알코홀이 촉매 반응에 의하여 산화되고 일종의 연료전지를 형성하고 알코홀의 함량에 따른 기전력의 변화를 감지하여 알코홀 농도를 측정하게 된다. 전기 화학적 측정법을 이용한 바이오센서(biosensor)의 경우 효소(enzyme)나 미생물 등의 생체물질을 전극 표면에 막(membrane)형태로 고정화(immobilization) 시켜 단일 효소나 다단계 효소 반응 결과로 생성되는 전극 활성화 물질을 H2O2전극, 산소전극, 암모니움(NH4+) 이온 선택성 전극, 이온 선택성 전계 효과 트랜지스터(ISFET) 등의 소자를 이용하여 측정할 수 있다. The alcohol measuring means may be an alcohol measuring sensor of the platinum catalyst method. Alcohol in the breath delivered to the platinum electrode is oxidized by a catalytic reaction to form a kind of fuel cell, and the alcohol concentration is measured by detecting a change in electromotive force according to the alcohol content. In the case of a biosensor using an electrochemical method, an electrode activator generated by a single enzyme or a multistage enzyme reaction by immobilizing a biomaterial such as an enzyme or a microorganism in the form of a membrane on an electrode surface.

The fuel supply control means can be achieved by adjusting the fuel control throttle valve by a stepping motor or other driving method, or by installing a drain valve before and after the fuel control throttle valve and opening and closing the drain valve.

상기 제어수단은 바람직하게는 마이크로 컴퓨터이다. 이 마이크로 컴퓨터는 소정의 알고리즘에 따라 음주측정값이 설정치 이상인 경우 상기 시동모터의 전류 개폐 수단을 '오프"하거나/하고 상기 연료공급조절수단에 의하여 연료공급을 중단하고 음주측정값이 설정치 이하인 경우 단계 별로 자동차 최대속도를 설정하여 연료공급조절수단에 의하여 연료공급을 조절할 수 있도록 연료공급조절수단을 제어한다.The control means is preferably a microcomputer. The microcomputer 'turns off' the current opening and closing means of the starting motor when the drinking measurement value is higher than or equal to the preset value according to a predetermined algorithm, and / or stops fuel supply by the fuel supply control means and when the drinking measurement value is lower than or equal to the setting value. By controlling the fuel supply control means to control the fuel supply by setting the maximum vehicle speed for each fuel supply control means.

상기 제어수단에 의한 상기 알고리즘의 수행방식을 도1과 도2를 참고하여 예를 들어 설명하면The method of performing the algorithm by the control means will be described with reference to FIGS. 1 and 2.

음주측정수단 센서의 신호를 받고 마이크로 컴퓨터는 시동개폐 스위치를 "오프"한다. 또한 마이크로 컴퓨터는 연료공급조절수단을 통하여 연료조절스롯틀밸브를 닫아 엔진의 연료공급을 중단한다. 시동이 걸리지 않게 되고 편법에 의하여 시동이 된 경우에도 기동이 되지 않게 한다.Upon receiving a signal from the breathalyzer sensor, the microcomputer “offs” the start / open switch. The microcomputer also closes the fuel control throttle valve through the fuel supply control means to stop the fuel supply to the engine. Do not start and do not start even if it is started by shortcut.

2). 시동을 걸기 전 알콜 농도 측정 시 혈중 알콜 농도가 0.05%미만이지만 수치가 어느 정도 나타나는 경우, 예를 들면;     2). If the alcohol level in the blood is less than 0.05% when the alcohol level is measured before starting, but the level appears to some extent, for example;

- 최고 속도를 60km/h로 제어한다(0.04%-0.049%인 경우).          -The maximum speed is controlled at 60 km / h (0.04% -0.049%).

- 최고 속도를 70km/h로 제어한다(0.02%-0.039%인 경우).          -The maximum speed is controlled at 70 km / h (0.02% -0.039%).

- 최고 속도를 80km/h로 제어한다(0.01%-0.019%인 경우).          -The maximum speed is controlled at 80 km / h (0.01% -0.019%).
