In this case, the electronic control unit 20 may dynamically control the first capacitor fan relay 31, the second capacitor fan relay 32, and the compressor relay 33 according to the battery condition of the vehicle and various load conditions. have.

상기 제1콘덴서팬릴레이(31)는 상기 전자제어유니트(20)에 의해 릴레이 코일(31-1)이 접지에 연결됨에 따라 릴레이 스위치(31-2)가 '온'되어, 배터리 전원(B+)을 제1콘덴서팬모터(34)로 공급하여 구동시키도록 되어 있다.In the first capacitor fan relay 31, as the relay coil 31-1 is connected to the ground by the electronic control unit 20, the relay switch 31-2 is 'on', so that the battery power source B + Is supplied to the first capacitor fan motor 34 to be driven.

상기 제2콘덴서팬릴레이(32)는 상기 전자제어유니트(20)에 의해 릴레이 코일(32-1)이 접지에 연결됨에 따라 상기 에어콘제어기(10)에서 드라이어압력스위치(37)를 통해 릴레이 구동용 전원이 공급되면 릴레이 스위치(32-2)가 '온'되어, 배터리 전원(B+)을 제2콘덴서팬모터(35)로 공급하여 구동시키도록 되어 있다.The second capacitor fan relay 32 is for driving the relay through the dryer pressure switch 37 in the air conditioner 10 as the relay coil 32-1 is connected to the ground by the electronic control unit 20. When the power is supplied, the relay switch 32-2 is turned on to supply and drive the battery power B + to the second capacitor fan motor 35.

또한, 상기 압축기릴레이(33)는 상기 전자제어유니트(20)에 의해 릴레이 코일(33-1)이 접지에 연결됨에 따라 상기 에어콘제어기(10)에서 드라이어압력스위치(37)를 통해 릴레이 구동용 전원이 공급되면, 릴레이 스위치(33-2)가 '온'되어, 배터리 전원(B+)을 마그네틱클러치(36)로 공급하여 압축기가 엔진의 구동력에 의해 구동되도록 한다.In addition, the compressor relay 33 is a relay power supply through the dryer pressure switch 37 in the air conditioner 10 as the relay coil 33-1 is connected to the ground by the electronic control unit 20. When this is supplied, the relay switch 33-2 is 'on', thereby supplying the battery power B + to the magnetic clutch 36 so that the compressor is driven by the driving force of the engine.

그리고, 상기 드라이어압력스위치(37)는 드라이어의 냉매압력에 따라 '온' 또는 '오프'되는 스위치로써, 드라이어의 냉매압력이 기준압력 보다 낮으면 '온'되어 상기 에어콘제어기(10)에서 공급되는 릴레이 구동용 전원을제2콘덴서팬릴레이(32)와 압축기릴레이(33)의 릴레이 코일(32-1, 33-1)로 공급하여 상기 제2콘덴서팬릴레이(32)와 압축기릴레이(33)를 '온'시키도록 되어 있다.In addition, the dryer pressure switch 37 is a switch that is 'on' or 'off' according to the refrigerant pressure of the dryer. When the refrigerant pressure of the dryer is lower than the reference pressure, the dryer pressure switch 37 is supplied from the air conditioner 10. Relay driving power is supplied to the relay capacitors 32-1 and 33-1 of the second capacitor fan relay 32 and the compressor relay 33 to supply the second capacitor fan relay 32 and the compressor relay 33. It is supposed to be 'on'.

상기와 같이 구성된 본 발명에 따른 자동차의 팬모터 구동회로의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the fan motor driving circuit of the vehicle according to the present invention configured as described above in detail.

운전자가 에어콘스위치를 '온'시키면 에어콘제어기(10)가 단자(P1)를 통해 릴레이 구동용 전원을 공급함과 더불어 단자(P2)를 통해 전자제어유니트(20)로 에어콘구동신호를 출력한다.When the driver 'turns on' the air conditioner switch, the air conditioner 10 supplies the relay driving power through the terminal P1 and outputs the air conditioner driving signal to the electronic control unit 20 through the terminal P2.

상기와 같이 에어콘 구동신호가 입력되면 상기 전자제어유니트(20)는 제1콘덴서팬릴레이(31)와 제2콘덴서팬릴레이(32) 및 압축기릴레이(33)의 각 릴레이 코일(31-1, 32-1, 33-1)을 접지에 연결한다.When the air conditioner driving signal is input as described above, the electronic control unit 20 relays each of the first capacitor fan relay 31, the second capacitor fan relay 32, and the compressor relay 33 to each of the relay coils 31-1 and 32. -1, 33-1) to ground.

따라서, 제1콘덴서팬릴레이(31)의 릴레이 코일(31-1)로 배터리 전원(B+)이 공급됨에 따라 상기 릴레이 코일(31-1)이 여자되어 릴레이 스위치(31-2)가 '온'되므로, 배터리 전원(B+)이 상기 제1콘덴서 릴레이(31)를 통해 제1콘덴서팬모터(34)로 공급되어 제1콘덴서팬모터(34)가 구동되는 것이다.Accordingly, as the battery power B + is supplied to the relay coil 31-1 of the first capacitor fan relay 31, the relay coil 31-1 is excited to turn on the relay switch 31-2. Therefore, battery power B + is supplied to the first capacitor fan motor 34 through the first capacitor relay 31 to drive the first capacitor fan motor 34.

한편, 상기 제2콘덴서팬릴레이(32) 및 압축기릴레이(33)는 드라이어 냉매 압력 변화에 따라 '온', '오프' 되는 드라이어압력스위치(37)를 통해 에어콘제어기(10)로부터 공급되는 릴레이 구동용 전원에 의해 동작하므로, 상기 제2 콘덴서팬릴레이(32) 및 압축기 릴레이(33)는 상기 제1콘덴서팬릴레이(31) 보다 드라이어 냉매 압력에 의해 상기 드라이어 압력 스위치가(37)가 '온' 되어지는 소정시간(예: 1sec) 지연되어 제2콘덴서팬모터(35) 및 마그네틱클러치(36)로 배터리 전원(B+)를 공급함으로써, 상기 제1콘덴서팬모터(34) 보다 소정시간 지연되어 제2콘덴서팬모터(35) 및 압축기가 구동된다.Meanwhile, the second capacitor fan relay 32 and the compressor relay 33 drive a relay supplied from the air conditioner 10 through a dryer pressure switch 37 that is 'on' and 'off' according to a change in dryer refrigerant pressure. Since the second condenser fan relay 32 and the compressor relay 33 are operated by a power supply for the dryer, the dryer pressure switch 37 is turned 'on' by the dryer refrigerant pressure than the first capacitor fan relay 31. After a predetermined time (for example, 1 sec) is delayed, the battery power supply B + is supplied to the second capacitor fan motor 35 and the magnetic clutch 36, thereby delaying the predetermined time than the first capacitor fan motor 34, and The two capacitor fan motor 35 and the compressor are driven.

즉, 상기 드라이어압력스위치(37)는 드라이어의 냉매압력에 따라 '온' 또는 오프'되므로, 상기 전자제어유니트(20)가 제1콘덴서팬릴레이(31)와 제2콘덴서팬릴레이(32) 및 압축기릴레이(33)의 각 릴레이 코일(31-1, 32-1, 33-1)을 접지에 연결하는 시점 보다 소정시간(예: 1sec) 지연되어 '온'되는 것이다.That is, the dryer pressure switch 37 is 'on' or 'off' according to the refrigerant pressure of the dryer, so that the electronic control unit 20 is the first capacitor fan relay 31 and the second capacitor fan relay 32 and The relay coils 31-1, 32-1, and 33-1 of the compressor relay 33 are 'on' after a predetermined time (for example, 1 sec.) Is delayed from the time of connecting the relay coils 31-1, 32-1, and 33-1 to ground.

이상에서 살펴본 바와 같이 본 발명에 따르면, 에어콘 구동시 2개의 콘덴서 팬모터중에서 하나의 팬모터를 소정시간 지연시켜 구동시킴으로써, 에어콘 구동시에 배터리 전압이 순간적으로 급격히 강하하지 않아 헤드램프의 깜박거림 현상을 제거할 수 있는 효과가 있다.As described above, according to the present invention, by driving one fan motor out of two condenser fan motors for a predetermined time while driving the air conditioner, the battery voltage does not suddenly drop rapidly when the air conditioner is driven, thereby causing a flicker of the head lamp. It can be removed.
