Description

차량용 유해가스 감지시스템{Air quality system for vehicle}Hazardous Gas Detection System for Vehicles {Air quality system for vehicle}

본 발명은 유해가스가 차실내로 유입되는 것을 차단하기 위한 감지시스템에 관한 것으로, 좀 더 상세하게는 센서에 의해 유해가스가 감지되면 차량의 창문을 닫을 수 있도록 안내하고, 차실내의 공기를 환기하여 이미 유입된 유해가스를 외부로 배출하도록 공조자동제어하는 차량용 유해가스 감지시스템에 관한 것이다.The present invention relates to a detection system for blocking the harmful gas flow into the vehicle cabin, and more particularly, when the harmful gas is detected by the sensor guides to close the window of the vehicle, ventilate the air in the vehicle cabin The present invention relates to a vehicle harmful gas detection system that automatically controls the air to discharge harmful gas already introduced to the outside.

근래에는 차량의 배기구를 통해 배출되는 유해가스가 주행중인 다른 차량의 공조기를 통해 실내로 유입되는 것을 방지하기 위한 유해가스 감지센서 및 차단시스템을 구비하고 있다.Recently, a harmful gas detection sensor and a blocking system are provided to prevent harmful gas discharged through an exhaust port of a vehicle from being introduced into the room through an air conditioner of another vehicle in operation.

그러나 일반적인 유해가스 감지센서는 차량의 전방하단에 설치되어 앞서 주행하는 차량의 배기구의 유해가스를 감지하는 것을 주된 목적으로 사용되고 있으나, 유해가스 감지에 따른 내외기 자동전환을 탑승자가 인지하기 어렵고, 이 때문에 탑승자가 창을 열게 되면, 창을 통해 유해가스가 차실내로 유입되는 것을 방지 할 수 없다.However, the general harmful gas detection sensor is installed in the lower front of the vehicle and used for the main purpose of detecting the harmful gas in the exhaust port of the preceding vehicle, but it is difficult for the occupant to recognize the automatic switching of the internal and external air according to the harmful gas detection. Therefore, when the occupant opens the window, it cannot prevent the harmful gas from entering the cabin.

또한 유해가스가 유입된 상태에서 창을 닫으면 내기모드로 공조 제어되기 때문에 차실내의 유해가스가 배출되지 않은 상태가 유지되어 유해가스가 혼입된 공기를 탑승자가 지속적으로 흡입하게 되는 결과를 낳는다.In addition, when the window is closed while the harmful gas is inflow, air conditioning is controlled in the bet mode, so that the harmful gas in the cabin is not discharged, resulting in the passenger continuously inhaling the air containing the harmful gas.

이러한 문제를 해소하기 위해 일본공개특허 제2003-165328호(차량용 공조장치)가 개시되어 있다.In order to solve this problem, Japanese Laid-Open Patent Publication No. 2003-165328 (vehicle air conditioner) is disclosed.

이에 의해 유해가스 감지센서에 의해 유해가스가 감지되면 자동으로 내기 모드로 전환하여 공조제어하고, 이를 탑승자에게 알려 탑승자가 유해가스를 인지하지 못한 상황에서 창을 여는 등 유해가스가 차실내로 유입될 수 있는 행동을 방지하고 있다.Accordingly, when harmful gas is detected by the harmful gas detection sensor, it automatically switches to betting mode for air conditioning control and informs the occupant of the harmful gas such as opening a window when the passenger does not recognize the harmful gas. To prevent possible behavior.

그러나 상기의 경우에도 차량 전방에 설치된 유해가스 감지센서의 한정된 범위 내에서만 유해가스를 감지하기 때문에 차량의 창문을 통해 유입되는 유해가스를 감지할 수 없고, 더욱이 이미 차실내로 유입된 유해가스를 실외로 배출하여 제거하지 못하는 종래의 문제가 그대로 유지되고 있다.However, even in the above case, since harmful gas is detected only within a limited range of the harmful gas detection sensor installed in front of the vehicle, it is impossible to detect harmful gas flowing through the window of the vehicle, and moreover, the harmful gas already introduced into the vehicle is outdoors. Conventional problems that cannot be removed by removal have been maintained.

본 발명은 상기와 같은 종래기술의 문제점을 개선하기 위한 것으로, 본 발명은 차량의 창문을 통해 유해가스가 유입되는 것을 방지하고, 이미 유입된 유해가스를 외부로 배출할 수 있도록 공조모드를 일정시간 환기모드로 제어하는 차량용 유해가스 감지시스템을 제공하는 데에 그 목적이 있다.The present invention is to improve the problems of the prior art as described above, the present invention is to prevent the harmful gas flows through the window of the vehicle, the air conditioning mode for a predetermined time to discharge the harmful gas already introduced to the outside The object is to provide a vehicle harmful gas detection system to control the ventilation mode.

상기와 같은 목적에 따른 본 발명은 차량의 전방에 설치되어 유해가스를 감지하는 제1 센서부와; 상기 제1 센서부의 유해가스 감지 여부에 따라 유해가스를 차단하고 공조장치의 내/외기 흡입 모드를 자동 전환하는 제어부로 구비되되; 차량의 측면으로 유입되는 유해가스를 감지하도록 차량의 창문에 인접한 위치에 설치되는 제2 센서부를 포함하는 것에 의해 달성된다.The present invention according to the above object is installed in the front of the vehicle and the first sensor for detecting harmful gas; It is provided as a control unit for blocking the noxious gas and automatically switching the internal / external air intake mode of the air conditioning apparatus according to the detection of the noxious gas of the first sensor unit; It is achieved by including a second sensor unit which is installed at a position adjacent to the window of the vehicle to detect the harmful gas flowing into the side of the vehicle.

이에 더해 상기 제2 센서부를 통해 유해가스가 감지되면 탑승자가 이를 인지할 수 있도록 알리는 알람수단을 더 포함하여 실시된다.In addition, when the harmful gas is detected through the second sensor unit is carried out further comprising an alarm means for informing the passenger to recognize this.

본 발명의 사용으로 차량의 창문을 통해 유해가스가 유입되는 것을 방지할 수 있고, 공조모드가 일정시간 환기모드로 자동제어되어 이미 유입된 유해가스를 실외로 배출하므로 차실내의 공기를 쾌적하게 유지할 수 있다.By using the present invention, it is possible to prevent harmful gas from flowing through the window of the vehicle, and the air conditioning mode is automatically controlled to a ventilation mode for a predetermined time, thereby discharging the harmful gas already introduced to the outside to keep the air in the cabin comfortable. Can be.

이하에서 본 발명의 실시예를 도시한 첨부도면을 통해 더욱 상세히 설명하기로 한다.Hereinafter will be described in more detail with reference to the accompanying drawings showing an embodiment of the present invention.

본 발명은 주행중 차실내로 유해가스가 유입되는 것을 감지 및 차단하기 위한 시스템으로 공조기를 통해 유입되는 유해가스와 더불어서 창을 통해 유입되는 유해가스를 감지하고, 이미 유입된 유해가스를 실외로 환기제어할 수 있도록 한 유해가스 감지시스템을 제공하고자 한다.The present invention is a system for detecting and blocking the inflow of harmful gas into the cabin while driving, in addition to the harmful gas introduced through the air conditioner to detect the harmful gas introduced through the window, and ventilation control the harmful gas already introduced to the outside To provide a hazardous gas detection system that can be.

이를 위해 도 2에서와 같이 차량의 전방에 설치되어 유해가스를 감지하는 제1 센서부(10)와; 상기 제1 센서부(10)의 유해가스 감지 여부에 따라 유해가스를 차단하고 공조장치의 내/외기 흡입 모드를 자동 전환하는 제어부(20)로 구비되되; 차량의 측면으로 유입되는 유해가스를 감지하도록 차량의 창문에 인접한 위치에 설치되는 제2 센서부(30)를 포함한다.To this end, the first sensor unit 10 is installed in front of the vehicle to detect harmful gases as shown in Figure 2; It is provided as a control unit 20 for blocking the noxious gas according to whether the first sensor unit 10 detects the noxious gas and automatically switches the internal / external air suction mode of the air conditioning apparatus; And a second sensor unit 30 installed at a position adjacent to a window of the vehicle to detect harmful gas flowing into the side of the vehicle.

제1 센서부(10)는 차량의 전방으로 공기의 유동이 많은 위치에 설치되어 주로 전방에 주행중인 차량의 배기구를 통해 배출되는 유해가스를 감지하고, 이를 통해 차량의 주행방향의 공기에 유해가스가 감지되면 후술하는 제어부(20)에 신호를 송출하여 차실내로 유해가스가 유입되는 것을 차단한다.The first sensor unit 10 is installed at a location where a lot of air flows to the front of the vehicle, and detects harmful gas discharged through the exhaust port of the vehicle which is mainly traveling in front of the vehicle, and thereby harmful gas to the air in the driving direction of the vehicle. When detected, the control unit 20 to be described later to send a signal to block the harmful gas flow into the vehicle interior.

제어부(20)는 제1 센서부(10)에서 유해가스를 감지하여 신호를 송출하면, 이를 수신하여 공조기의 공조 모드를 내기모드로 자동 전환함으로서, 외부의 공기가 실내로 유입되는 것을 차단한다.When the first sensor unit 10 detects harmful gas and transmits a signal, the control unit 20 automatically receives the signal and automatically switches the air conditioning mode to the bet mode, thereby preventing external air from entering the room.

제2 센서부(30)는 차량의 양측 사이드 미러에 설치되어 창을 통해 실내로 유해가스가 유입되는 것을 감지하여 제어부(20)에 신호를 송출하는 것으로, 이는 제2 센서부(30)를 통해 유해가스가 감지되는 경우에는 창을 통해 유해가스가 차실내로 유입될 가능성이 있다고 판단하고, 이때에는 창문을 닫을 수 있도록 탑승자에게 인지시키게 된다.The second sensor unit 30 is installed at both side mirrors of the vehicle and detects that harmful gas flows into the room through a window, and transmits a signal to the control unit 20, which is transmitted through the second sensor unit 30. If noxious gas is detected, it is determined that harmful gas may be introduced into the cabin through the window, and in this case, the occupant is notified to close the window.

이를 위해 본 발명은 알람수단(35)을 포함하는데, 이는 탑승자에게 외부 공기에 유해가스가 혼입되어 있음을 인지시켜 탑승자가 창문을 임의로 여는 것을 막고, 이에 의해 유해가스가 창을 통해 차실내로 유입되는 것을 방지한다.To this end, the present invention includes an alarm means 35, which prevents the occupant from arbitrarily opening the window by notifying the occupant that harmful gas is mixed in the outside air, thereby introducing harmful gas into the cabin through the window. Prevent it.

이때 제2 센서부(30)로부터 신호를 감지하여 알람수단(35)을 작동하거나 환기모드를 수행하는 것은 제어부(20) 또는 별도의 보조 제어부를 통해 제어할 수 있다.In this case, the operation of the alarm means 35 or the ventilation mode by sensing the signal from the second sensor unit 30 may be controlled through the control unit 20 or a separate auxiliary control unit.

이처럼 알람수단(35)은 탑승자에게 유해가스 여부를 빠르게 인지시킬 필요가 있기 때문에 비프음, LED램프 또는 자동온도조절장치(100)의 LCD(110)를 사용하여 탑승자에게 알리는 것으로 설치되고, 이 알람수단(35)을 탑승자가 별도의 스위치를 조작하여 끌 수 있도록 한다.As such, the alarm means 35 is installed by informing the occupant by using the LCD 110 of the beep sound, LED lamp or the thermostat 100 because it is necessary to quickly recognize whether or not the harmful gas to the occupant, this alarm The means 35 allows the occupant to turn off by operating a separate switch.

상기 알람수단(35)은 유해가스가 감지된 상태에서 창문이 열린 경우, 창을 닫도록 권고하는 알림 기능을 포함하여 실시되는데, 이는 공조 모드를 내기모드로 전환하더라도 탑승자가 창을 임의로 열면 외부의 유해가스가 차실내로 유입되는 것을 차단할 수 없기 때문에 이를 방지하기 위함이다.The alarm means 35 is implemented to include a notification function for recommending to close the window when the window is opened in the state that the harmful gas is detected, which is the external even if the passenger arbitrarily open the window even if the air conditioning mode is switched to bet mode This is to prevent harmful gas because it can not block the flow into the cabin.

더욱이 유해가스가 유입된 채로 열린 창을 닫으면 공조기가 내기모드로 자동 전환되어 제어되기 때문에 유입된 유해가스가 실내에 계속 머무르게 된다.Moreover, when the open window is closed with the harmful gas inflowed, the air conditioner is automatically switched to the betting mode and controlled so that the harmful gas is kept in the room.

따라서 이러한 문제를 해소하기 위해 본 발명은 유해가스가 감지되면, 제어부(20)는 창의 개폐 유무와 개도량을 감지하고, 탑승자의 조작에 의해 창이 완전히 닫히기까지 소요된 시간과 유해가스의 농도에 따라 차실내의 공기를 환기모드로 제어되도록 하는 기능을 포함한다.Therefore, in order to solve this problem, the present invention, when harmful gas is detected, the control unit 20 detects the presence or absence and opening amount of the window, according to the time required to close the window completely by the operation of the occupant and the concentration of harmful gas It includes a function to control the air in the cabin in the ventilation mode.

이하에서는 상기 제어부(20)의 실시예를 통해 좀 더 상세히 설명하기로 한다.Hereinafter, the embodiment of the control unit 20 will be described in more detail.

<제1 실시예><First Embodiment>

차량의 개폐여부와 개도량의 감지가 불가능한 차량의 경우;In the case of a vehicle that cannot detect whether the vehicle is opened or closed;

도 3에서와 같이 자동온도조절장치가 작동된 후(S100'), 탑승자가 유해가스 감지시스템을 작동하면(S200'), 차량에 설치된 제2 센서부(30)는 각각 실외 공기에 유해가스가 혼입되어 있는지를 감지하고(S300'), 유해가스가 감지되면 탑승자에게 창문이 열린 경우에는 창문을 닫을 수 있게 하고, 창문이 닫힌 경우에는 임의로 열지 않도록 권고하는 알람수단(35)을 작동한다(S530).After the thermostat is operated as in FIG. 3 (S100 ′), when the occupant operates the hazardous gas detection system (S200 ′), the second sensor unit 30 installed in the vehicle has harmful gases in the outdoor air, respectively. It is detected whether it is mixed (S300 '), if the harmful gas is detected to enable the occupant to close the window if the window is opened, and if the window is closed to operate the alarm means (35) to recommend not to open (S530) ).

알람수단(35)의 작동후 유해가스의 농도에 따라 차실내로 유입 가능한 유해가스의 혼입 정도를 연산하고, 연산된 결과에 따라 제어부(20)는 일정시간을 환기모드로 제어하여 차실내 공기를 환기시킨다(S531).After the operation of the alarm means 35 calculates the degree of mixing of harmful gas that can be introduced into the cabin according to the concentration of the harmful gas, and according to the calculated result, the control unit 20 controls the air in the cabin by a predetermined time in the ventilation mode. Ventilate (S531).

환기모드가 완료되면 제어부(20)는 공조기를 내기모드로 전환하여 제어하고(S600'), 제1, 2 센서부(10, 30)를 통해서 유해가스를 지속하여 감지한다.When the ventilation mode is completed, the control unit 20 controls the air conditioner by switching to the bet mode (S600 ') and continuously detects harmful gases through the first and second sensor units 10 and 30.

이때 유해가스가 감지되지 않으면 알람수단(35)을 정지시키고(S720'), 유해가스가 지속하여 감지되는 경우에는 알람수단(35)을 통한 알림을 계속한다.In this case, if no harmful gas is detected, the alarm means 35 is stopped (S720 ′), and if noxious gas is continuously detected, the notification through the alarm means 35 is continued.

<제2 실시예>Second Embodiment

차량의 창문 개폐여부와 개도량의 감지가 가능한 차량의 경우;For vehicles that can detect whether the window opening and opening of the vehicle can be detected;

도 4에서와 같이 자동온도조절장치가 가동된 상태에서(S100) 탑승자가 유해가스 감지시스템(Air quality system, AQS)를 작동시켰는가를 판단하고(S200), 차량에 설치된 제2 센서부(30)에서 유해가스를 감지한다.In the state in which the thermostat is operated as shown in FIG. 4 (S100), it is determined whether the occupant has operated the hazardous gas detection system (Air quality system, AQS) (S200), and the second sensor unit 30 installed in the vehicle. Detect harmful gases from

이때 제2 센서부(30)에서 유해가스를 감지하면(S300), 먼저 차량의 창문이 개폐되어 있는가를 판단하며(S400), 이와 동시에 공조 모드를 전환하여 외기가 실내로 유입되지 않게 한다.At this time, when the second sensor unit 30 detects noxious gas (S300), it is first determined whether the window of the vehicle is opened or closed (S400), and at the same time, the air conditioner is switched to prevent the outside air from entering the room.

창문이 열려있으면 탑승자가 창문을 닫을 수 있도록 알람수단(35)을 이용해 인지시키고(S520), 알람수단(35)의 작동시 창문이 열려있던 개도량 정보를 제어부(20)로 송출한다(S521).If the window is open, the occupant is recognized using the alarm means 35 so as to close the window (S520), and when the alarm means 35 operates, the opening degree information of the window is opened to the control unit 20 (S521). .

창문의 개도량 정보를 수신하는 제어부(20)는 유해가스를 감지하여 창문이 완전히 닫히기까지 소요된 시간과, 개도량 및 유해가스의 농도를 감안하여 차실내 공기를 환기시킬 환기모드 제어시간을 연산한다(S522).The control unit 20 that receives the opening amount information of the window calculates the time required for the window to be completely closed by detecting the harmful gas and the ventilation mode control time to ventilate the air in the vehicle in consideration of the opening amount and the concentration of the harmful gas. (S522).

한편, 차량의 창문이 열리지 않고 닫힌 상태인 경우, 바로 알람수단(35)을 통해 탑승자에게 외기에 유해가스가 혼입되어 있음을 인지시키고(S510), 외기가 차실내로 유입되는 것을 차단하는데, 이미 유해가스가 차실내로 유입되었을 가능성이 있기 때문에 감지된 유해가스 농도에 따라 차실내의 공기를 적정시간 환기모드로 제어한다(S511).On the other hand, if the window of the vehicle is not opened without closing, immediately through the alarm means 35 to the occupant to recognize that harmful gas is mixed into the outside air (S510), but to block the outside air flow into the cabin, Since noxious gas may have flowed into the cabin, the air in the cabin is controlled in a proper time ventilation mode according to the detected noxious gas concentration (S511).

환기모드를 일정시간 작동시켜 차실내에 유해가스가 잔존할 가능성을 해소하면 공조모드를 내기모드로 전환하고(S600), 제1, 2 센서부(10, 30)에서는 지속적으로 유해가스를 감지하여 현재 실외 공기에 유해가스가 혼입되어 있는가를 판단한다(S700).When the ventilation mode is operated for a certain time to eliminate the possibility of harmful gas remaining in the vehicle, the air conditioning mode is switched to the bet mode (S600), and the first and second sensor units 10 and 30 continuously detect the harmful gas. It is determined whether harmful gas is presently mixed in the outdoor air (S700).

제1, 2 센서부(10, 30)에서 유해가스가 더 이상 감지되지 않으면 작동된 알람수단(35)을 정지시키고(S720), 유해가스가 감지되면 알람수단(35)을 계속 작동시켜 탑승자에게 알린다(S710).When the harmful gas is no longer detected by the first and second sensor units 10 and 30, the alarm means 35 is stopped (S720), and when the harmful gas is detected, the alarm means 35 is continuously operated to the occupant. Inform (S710).

이때 알람수단(35)이 비프음과 LED램프 등으로 실시되면, 탑승자가 임의로 정지시킬 수 있도록 작동스위치를 포함하여 실시된다.At this time, when the alarm means 35 is implemented with a beep sound and an LED lamp, it is implemented including an operation switch so that a passenger can freely stop.
