When operated without changing the quantity, it consists of an electronic control unit that outputs a control signal to the window drive motor to open and close the window for a certain time.

이하, 본 발명에 의한 차량용 어린이 보호 장치의 바람직한 일실시예를 첨부된 도면을 통해 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of a child protection device for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 차량용 어린이 보호 장치의 블록 회로도이고, 도 2는 본 발명에 의한 차량용 어린이 보호 장치를 설명하기 위한 플로우챠트이다.1 is a block circuit diagram of a child protection device for a vehicle according to the present invention, Figure 2 is a flow chart for explaining the child protection device for a vehicle according to the present invention.

본 발명에 의한 차량용 어린이 보호 장치는 알피엠 센서(10)와, 풍속량 감지 센서(20)와, 적외선 센서(30)와, 전자 제어 유니트(40)로 구성된다.A child protection apparatus for a vehicle according to the present invention includes an RPM sensor 10, a wind speed sensor 20, an infrared sensor 30, and an electronic control unit 40.

먼저, 상기 알피엠 센서(10)는 엔진(미도시)의 회전수를 검출하도록 이의 일측에 설치된다.First, the RF sensor 10 is installed on one side thereof to detect the rotation speed of the engine (not shown).

그리고, 상기 풍속량 감지 센서(20)는 에어컨(미도시)이나 히터(미도시)에서 발생되는 풍속량을 검출하도록 벤틸레이션(미도시)의 일측에 설치된다.The wind speed sensor 20 is installed at one side of the ventilation (not shown) to detect the wind speed generated from an air conditioner (not shown) or a heater (not shown).

또한, 상기 적외선 센서(30)는 차실 내에 탑승자가 존재하는지의 여부를 적외선을 조사시켜 검출하도록 차실 내의 일측에 설치된다.In addition, the infrared sensor 30 is installed at one side of the vehicle interior to irradiate and detect the presence of occupants in the vehicle interior.

한편, 상기 전자 제어 유니트(40)는 상기 알피엠 센서(10)와, 풍속량 감지 센서(20)와, 적외선 센서(30)의 출력 신호를 입력받아 차량의 엔진이 공회전 상태이고, 차실 내에 탑승자가 존재하며, 일정 시간동안 에어컨이나 히터에서 풍속량의 변화없이 지속적으로 차실 내로 유입되면 윈도우 개폐 모터(1)를 구동시켜 차실 내로 환기시키도록 상기 알피엠 센서(10)와, 풍속량 감지 센서(20)와, 적외선 센서(30)의 출력단에 연결되고, 상기 윈도우 모터(1)의 신호 입력단에 연결된다.On the other hand, the electronic control unit 40 receives the output signal from the RF sensor 10, the wind speed sensor 20, and the infrared sensor 30, the engine of the vehicle is idle, the occupant in the cabin It exists, and the ALPM sensor 10 and the wind speed detection sensor 20 to drive the window opening and closing motor (1) to ventilate into the cabin when the air flow continuously in the cabin without a change in the air flow rate for a predetermined time. And, it is connected to the output terminal of the infrared sensor 30, it is connected to the signal input terminal of the window motor (1).

이하, 본 발명에 의한 차량용 어린이 보호 장치의 작용을 도 2의 플로우챠트를 사용하여 설명한다.Hereinafter, the operation of the child protection device for a vehicle according to the present invention will be described using the flowchart of FIG. 2.

먼저, 전자 제어 유니트(40)는 알피엠 센서(10)와 풍속량 감지 센서(20)의 출력 신호를 입력받아 차량의 엔진 회전 여부와 에어컨 또는 히터의 작동과 풍속량의 변화를 판단한다.(S1~S3)First, the electronic control unit 40 receives the output signals of the RPM sensor 10 and the wind speed sensor 20 to determine whether the engine rotates, the operation of the air conditioner or the heater, and the change of the wind speed. ~ S3)

그리하여, 엔진이 일정 이하(공회전 상태)로 회전되고, 상기 에어컨 및 히터가 일정 이상 시간으로 풍속량의 변화없이 작동되면 적외선 센서(30)의 출력 신호를 입력받아 어린이(탑승자)의 존재 여부를 판단한다.(S4,S5)Thus, when the engine is rotated below a certain level (idle state), and the air conditioner and the heater are operated without changing the wind speed for a predetermined time or more, the output signal from the infrared sensor 30 is input to determine the presence of a child (rider). (S4, S5)

그리하여, 차실 내에 어린이가 존재하면 윈도우 개폐 모터(1)로 제어 신호를 출력하여 윈도우를 잠시동안 개방한 후 다시 닫아 차실 내에 존재하는 어린이가 질식사하는 것을 방지한다.(S6)Thus, if a child is present in the cabin, a control signal is output to the window opening / closing motor 1 to open the window for a while and then close again to prevent the child present in the cabin from choking.

이상에서 설명한 바와 같이 어린이가 차량에 혼자 남겨진 상태에서 엔진이 공회전되고, 에어컨이나 히터가 일정시간동안 풍속량의 변화없이 작동되면 자동으로 윈도우를 개폐시켜 어린이가 질식하는 것을 방지할 수 있다.As described above, when the engine is idle while the child is left alone in the vehicle and the air conditioner or the heater is operated for a predetermined time without changing the wind speed, the window can be automatically opened and closed to prevent the child from choking.
