본 고안은 차량의 음주운전 방지장치에 관한 것으로, 보다 상세하게는 운전자가 탑승한 상태에서 안전벨트를 착용하고 시동을 걸기 위한 시도가 행해지면 알콜농도검출센서에 의해 검출되는 운전자의 알콜농도가 규정치 이상으로 되는 경우 시동이 걸리지 않도록하여 음주운전 방지하도록 된 차량의 음주운전 방지장치에 관한 것이다.The present invention relates to a device for preventing drunk driving of a vehicle. More specifically, when an attempt is made to put on a seat belt and start the vehicle while the driver is on board, the alcohol concentration of the driver detected by the alcohol concentration detection sensor is determined. The above case relates to a drunk driving prevention device of a vehicle which is configured to prevent drunk driving by preventing starting.
주지된 바와 같이, 현대사회의 필수적인 이기(利器)로서 알려진 자동차는 그 운전시 항시 안전사고에 관련해서 주의가 필요하게 되지만, 운전자가 규정치 이상의 알콜농도로 음주한 상태에서 차량을 운전하는 경우 인사사고를 포함하는 심각한 안전사고의 유발가능성이 존재하게 된다.As is well known, automobiles known as essential selfishness in modern society require caution regarding safety accidents at all times while driving, but if a driver drives a vehicle with a alcohol level exceeding the prescribed level, There is a possibility of causing a serious safety accident, including.
따라서, 통상적으로는 운전자의 음주운전을 방지하기 위해 특정한 지역에서 알콜농도측정기를 사용하여 음주측정을 하는 단속이 행해지기는 하지만, 그러한 음주운전의 단속은 상당히 비현실적이어서 단속자와 운전자간의 빈번한 마찰을 초래하는 실정이고 그러한 음주단속에 의해서도 음주운전의 효과적인 방지는 달성되지 않는 실정이다.Therefore, although the use of alcohol concentration metering is often used to prevent drunk driving in certain areas to prevent driver's drunk driving, such drunk driving is quite unrealistic and causes frequent friction between the chopper and the driver. It is a situation that does not achieve effective prevention of drunk driving even by such drunk enforcement.
그러한 점을 고려하여, 운전자의 음주운전을 예방하기 위한 수단으로서 차량의 적정한 위치, 예를 들면 운전석 전바에 알콜농도검출센서를 부가해서 알콜농도가 규정치 이상으로 검출되는 경우에는 차량의 시동이 걸리지 않도록 하는 방안도 제안된 바 있지만, 운전자가 음주한 상태에서도 비음주자가 차량의 시동을 걸어주게 되면 차량이 운행가능한 상태로 되므로, 결국 알콜농도의 검출만에 의한 음주운전 방지는 그 효과적인 면에서 불리함이 많이 된다.In view of this, as a means to prevent the driver's drunk driving, by adding an alcohol concentration sensor to a proper position of the vehicle, for example, the front of the driver's seat, the vehicle is not started if the alcohol concentration is detected above a prescribed value. Although a method has been proposed, even if the driver drunk the vehicle while the driver is drunk, the vehicle becomes in a state of operation, and thus, the prevention of drunk driving only by detecting the alcohol concentration is disadvantageous in terms of its effectiveness. This is a lot.

The seat belt wearing detection unit 10 has a movable contact 11a fixed to the seat belt buckle 10a and a seat belt tongue 10b inserted into the buckle 10a, as illustrated in FIG. In this case, a switch 11 comprising a process contact 11b connected to the movable contact 11a to provide a switching signal indicating a seat belt wearing state, and a resistance between the switch 11 and the resistor 12; A base is connected via (13) and a transistor 14 for outputting a seat belt wearing signal between the emitter and the resistor 15 is configured.

The ND gate 42 is shown, and 60 denotes an engine control unit that starts the engine based on the engine start signal applied from the logical AND gate 42.
이어, 그와 같이 구성된 본 고안에 따른 음주운전 방지장치의 동작에 대해 설명한다.Next, the operation of the drunk driving prevention device according to the present invention configured as described above.
그 상태에서 운전자가 시동키를 시동키 홀더에 삽입하고나서 시동위치로 절환하게 되면 상기 운전석 안전벨트 착용에 의해 트랜지스터(23)가 도통상태로 되고, 그 에 따라 그 트랜지스터(23)의 에미터와 저항(24)과의 사이에서는 안전벨트 착용하에서의 시동신호가 출력되어 상기 엔진시동제어부(40)의 논리AND게이트(42)의 일단에 인가된다.In this state, when the driver inserts the ignition key into the ignition key holder and switches to the ignition position, the transistor 23 is turned on by wearing the driver's seat belt. Accordingly, the emitter and the emitter of the transistor 23 A start signal under the seat belt is output between the resistor 24 and one end of the logic AND gate 42 of the engine start controller 40.
먼저, 운전자가 운전석에 탑승하여 안전벨트를 착용하게 되면 상기 안전벨트착용 스위치(11)의 가동접점(11a)이 고정접점(11b)에 접속되고, 그에 따라 트랜지스터(14)가 도통상태로 되어 그 에미터와 저항(15)사이에서는 안전벨트착용신호가 출력되고, 그 안전벨트착용신호는 저항(21)을 매개하여 트랜지스터(23)의 베이스에 인가된다.First, when the driver gets into the driver's seat and wears the seat belt, the movable contact 11a of the seat belt seat switch 11 is connected to the fixed contact 11b, whereby the transistor 14 is brought into a conductive state. A seat belt wearing signal is output between the emitter and the resistor 15, and the seat belt wearing signal is applied to the base of the transistor 23 via the resistor 21.
그때, 상기 알콜농도검출센서(30)에서는 운전자의 알콜농도를 검출하게 되는 바, 그 알콜농도검출센서(30)는 예컨대 알콜농도가 높게 검출될수록 로우레벨의 신호를 출력하도록 구성하고, 그 알콜농도검출신호는 인버터(41)의 임계치(threshold value) 이하인 경우 인버터(41)에서 하이레벨로 반전처리되어 상기 논리AND게이트(42)의 다른단에 인가된다.At this time, the alcohol concentration detection sensor 30 detects the driver's alcohol concentration, the alcohol concentration detection sensor 30 is configured to output a low level signal as the alcohol concentration is detected, for example, the alcohol concentration When the detection signal is less than or equal to the threshold value of the inverter 41, the inverter 41 is inverted to a high level and applied to the other end of the logic AND gate 42.
따라서, 상기 논리AND게이트(42)는 안전벨트가 착용된 상태에서 시동키가 시동위치로 절환되어 생성되는 시동신호와 상기 알콜농도검출센서(30)에 의해 검출된 운전자의 알콜농도가 규정치 이하로 검출되는 경우에만 논리AND게이트(42)에서 하이레벨의 엔진시동제어신호가 출력되고, 그에 따라 엔진제어부(60)에서는 해당 차량의 엔진이 시동상태로 되도록 제어하게 된다.Accordingly, the logic AND gate 42 has a start signal generated by switching the ignition key to the start position in a state where the seat belt is worn and the alcohol concentration of the driver detected by the alcohol concentration detection sensor 30 is below a prescribed value. Only when it is detected, a high level engine start control signal is output from the logic AND gate 42, and accordingly, the engine control unit 60 controls the engine of the vehicle to be in a start state.
여기서, 상기 엔진제어부(50)는 상기 알콜농도 검출센서(30)에 의해 검출되는 알콜농도검출신호에 대해 소정의 지연시간을 유지하여 엔진의 시동을 제어하도록 하면 예컨대 엔진의 시동이 걸리도록 하거나 운전석측에 중량검출센서를 설치해서 그 중량검출센서에 의해 검출되는 운전석 탑승자의 중량이 변화되지 않는 상태에서만 시동이 걸리도록 하므로써 음주자를 대신하여 시동을 걸어주는 일을 방지하는 구성도 가능함은 물론이다.Here, the engine controller 50 maintains a predetermined delay time with respect to the alcohol concentration detection signal detected by the alcohol concentration detection sensor 30 to control the start of the engine, for example, so that the engine is started or the driver's seat It is also possible to install a weight detection sensor on the side so that the start of the driver's seat detected by the weight detection sensor is started only in the state that the weight does not change, thereby preventing the starting of the drink on behalf of the drinker.
이상에서 설명한 바와 같이, 본 고안에 따른 음주운전 방지장치에 의하면, 안전벨트가 착용되지 않은 상태에서는 시동상태로 되지 않게 되어 안전벨트의 상시적인 착용이 유도되고, 또한 알콜농도가 규정치 이상으로 검출되는 경우에는 안전벨트와 시동스위치가 접속되는 경우에도 엔진의 시동제어신호가 생성되지 않게 되므로, 음주운전의 방지효과가 보다 향상될 수 있게 된다.As described above, according to the drunk driving prevention apparatus according to the present invention, when the seat belt is not worn, it does not become a starting state, which leads to the constant wearing of the seat belt, and the alcohol concentration is detected above a prescribed value. In this case, even when the seat belt and the start switch are connected, the start control signal of the engine is not generated, thereby preventing the drunk driving effect.
한편, 상기 알콜농도 검출센서(30)는 핸들상에 설치된 경우가 예시되어 있지만, 그 알콜농도 검출센서(30)의 설치위치는 예컨대 인스트루먼트 패널과 같은 운전자의 알콜농도를 검출하기에 적절한 위치에 설치될 수도 있다.On the other hand, although the alcohol concentration detection sensor 30 is installed on the handle is illustrated, the installation position of the alcohol concentration detection sensor 30 is installed at a position suitable for detecting the alcohol concentration of the driver, such as an instrument panel, for example.
