본 발명은 자동차용 공조제어방법에 관한 것으로서, 더욱 상세하게는, 실내,외 온도와, 일사량 및 냉각수온도가 일정한 조건을 만족할 경우에만 "난방기동제어모드"로 전환되도록 함으로써, 뜨거운 바람이 디프로스트 벤트를 통해 탑승자 또는 운전자의 머리 쪽으로 토출되지 않도록 하여 쾌적성을 유지하도록 하는 자동차용 공조제어방법에 관한 것이다.The present invention relates to a vehicle air conditioning control method, and more particularly, by switching to the "heating start control mode" only when the indoor and outdoor temperature, the solar radiation amount and the coolant temperature satisfy certain conditions, the hot wind is defrosted The present invention relates to a vehicle air conditioning control method for maintaining comfort by not being discharged toward the head of a passenger or driver through a vent.

일반적으로, 자동차에는 쾌적한 실내를 유지시키기 위한 공조장치와 이 공장치를 조절하기 위한 컨트롤러가 구비되어 있다.In general, a vehicle is provided with an air conditioner for maintaining a comfortable interior and a controller for adjusting the plant value.

상기 자동차용 공조장치는, 공조케이스와, 상기 공조케이스의 일측에 구비되는 송풍기와, 상기 공조케이스의 내측에 구비되는 증발기와, 상기 공조케이스의 내측에 구비되는 히터코어(Heater Core)와, 상기 공조케이스의 내측에 구비되고 상기 증발기 및 히터코어를 통과하는 냉기 또는 온기가 적정한 공조공기로 혼합되도록 조절하는 온도조절도어와, 상기 공조케이스 내에 구비되고 자동차의 각 부위 즉, 디프로스트(Defrost), 페이스(Face), 플로어(Floor) 측으로 공조공기가 토출되도록 유로가 형성된 벤트(Vent), 및 상기 공조케이스 내에 구비되고 벤트를 통해 토출되는 공기의 량을 제어하는 도어를 포함하여 구성된다.The air conditioner for a vehicle includes an air conditioning case, a blower provided at one side of the air conditioning case, an evaporator provided inside the air conditioning case, a heater core provided inside the air conditioning case, A temperature control door provided inside the air conditioning case and configured to mix cool air or warm air passing through the evaporator and the heater core with a suitable air conditioning air, and each part of the air conditioner, that is, a defrost, It includes a face (Vent), the flow path is formed so that the air is discharged to the floor (Floor) side, and the door provided in the air conditioning case and controls the amount of air discharged through the vent.

도 1에 도시된 바와 같이, 종래의 차량의 시동시 난방 제어방법은, 차량이 시동된 후 난방모드로 공조장치를 작동시키면 난방기동제어 진입조건에 해당되는지를 확인하는 단계와, 난방기동제어 진입조건에 해당되면 난방기동제어 해제조건을 만족할 때까지 난방기동제어를 실시하는 단계와, 난방기동제어 해제조건을 만족하면 난방기동제어를 중지하고 자동제어를 실시하는 단계로 구성된다.As shown in Figure 1, the heating control method at the start of the conventional vehicle, the step of confirming whether the condition to enter the heating start control when operating the air conditioner in the heating mode after the vehicle is started, the heating start control entry If the condition is satisfied, the heating start control is performed until the heating start control release condition is satisfied, and if the heating start control release condition is satisfied, the heating start control is stopped and the automatic control is performed.

상기 난방기동제어 진입조건이란, 공조장치를 자동제어모드로 제어시 플로어 토출모드인 상태에서 외기온이 10℃이하고, 냉각수온이 73℃ 이하인 조건을 모두 만족하는 것을 말한다. 물론, 상기 난방기동제어 해제조건은 상기한 난방기동제어 진입조건을 벗어나는 것을 의미하며, 냉각수온이 73℃를 초과하면 난방기동제어를 중지한다.The heating start control entry condition means that both the outside air temperature is 10 ° C. and the cooling water temperature is 73 ° C. or less in the state of the floor discharge mode when the air conditioner is controlled in the automatic control mode. Of course, the heating start control release condition means that the heating start control entry condition is not exceeded, and the heating start control is stopped when the cooling water temperature exceeds 73 ° C.

여기서, 난방기동제어는 시동 초기에 외부에서 유입되는 찬공기가 발 부분으로 토출되지 않도록 토출 방향을 조정하고 풍량을 서서히 증대시키는 제어 로직이다.Here, the heating start control is control logic that adjusts the discharge direction and gradually increases the amount of air so that cold air introduced from the outside at the initial stage of startup is not discharged to the foot.

즉, 난방기동제어는 시동 초기에는 디프로스트 토출모드(Def)로 한 상태에서 블로어의 전압을 로우(Low), 즉, 블로어의 단수를 최하단으로 유지하다가 엔진 냉각수의 온도가 일정 온도에 도달하면, 혼합토출모드(Mix)로 설정하고, 블로어의 전압을 점차 상승시켜 감으로써 서서히 난방을 시작하게 된다. 여기서, 혼합토출모드라 함은, 상측의 디프로스트 벤트와 플로어 벤트로 공기가 토출되는 모드이다.That is, the heating start control maintains the blower voltage as low as the defrost discharge mode (Def) at the initial stage of start-up, that is, when the stage of the blower reaches the lowest level and the temperature of the engine coolant reaches a certain temperature. The heating is started gradually by setting the mixed discharge mode (Mix) and gradually increasing the blower voltage. Here, the mixed discharge mode is a mode in which air is discharged to the upper defrost vent and the floor vent.

그런데, 종래의 난방기동제어방법은, 외부조건 등에 의해 실내가 충분히 따뜻함에도 난방기동제어 모드로 인식하여 공조장치가 작동되면, 송풍공기가 플로어모드가 아닌 토출모드로 전환되어 자동차 실내의 따뜻한 공기가 운전자 또는 탑승자의 머리측으로 송풍됨에 따라 불쾌감을 유발시키는 문제점이 있다.However, in the conventional heating start control method, when the air conditioner is operated by recognizing the heating start control mode even though the room is sufficiently warm due to external conditions, the blower air is switched to the discharge mode instead of the floor mode, so that warm air in the vehicle interior is maintained.

상기 제어부는, 실외온센서를 통해 측정되는 외기온도가 기준 외기온도 이하일 경우에 저온영역으로 인식한다. 상기 기준 외기온도는 약 20℃를 기준으로 한다.The controller recognizes the low temperature area when the outside temperature measured by the outdoor temperature sensor is equal to or less than the reference outside temperature. The reference outside air temperature is based on about 20 ° C.

또한, 상기 자동차 공조장치는, 자동차의 실내온도를 측정하고 이를 상기 제어부로 전송하도록 구비된 인카센서를 포함한다.In addition, the vehicle air conditioner includes an in-car sensor provided to measure the room temperature of the vehicle and transmit it to the controller.

상기 제어부는, 인카센서를 통해 측정된 차실내 온도가 기준 내기온도 이하일 경우에 저온영역으로 인식한다. 상기 기준 내기온도는 약 15℃를 기준으로 한다.The controller recognizes the low temperature region when the vehicle interior temperature measured by the in-car sensor is equal to or lower than the reference internal temperature. The reference bet temperature is based on about 15 ℃.

The reference solar radiation is based on about 0.3V.

또한, 상기 자동차용 공조장치는, 엔진에서 히터코어로 순환되는 냉각수온도를 측정하고 이를 상기 제어부로 전송하도록 구비된 냉각수온센서를 포함한다.In addition, the vehicle air conditioner includes a coolant temperature sensor provided to measure the coolant temperature circulated from the engine to the heater core and transmit it to the controller.

The reference coolant temperature is based on about 73 ° C.

또한, 도 2에 도시된 바와 같이, 저온영역의 냉각수온도에 따라 모드를 변환한다.In addition, as shown in Figure 2, the mode is switched according to the coolant temperature in the low temperature region.

즉, 냉각수온도가 제1기준온도인 약 40 ~ 43℃ 범위에서는, 디프로스트 벤트로 공기를 공급하는 모드인 디프로스트 모드가 실행되고, 제2기준온도인 약 43 ~ 46℃ 범위에서는, 디프로스트 벤트 및 플로어 벤트로 공기를 공급하는 모드인 믹스모드이며, 상기 제2기준온도를 초과할 경우에는 플로어 벤트로 공기를 공급하는 플로어 모드가 실행된다.That is, in the range of about 40 to 43 ° C. where the cooling water temperature is the first reference temperature, the defrost mode, which is a mode for supplying air to the defrost vent, is executed.

상기와 같이 구성된 자동차용 공조장치의 "난방기동제어모드"에 따른 공조제어방법을 살펴보면 다음과 같다.Looking at the air conditioning control method according to the "heating start control mode" of the vehicle air conditioning apparatus configured as described above are as follows.

먼저, 도 3을 참조하면, 외기온도가 기준 외기온도 이하인지를 판단하는 단계이다(S1).First, referring to FIG. 3, it is a step of determining whether the outside air temperature is lower than the reference outside air temperature (S1).

이는, 실외온센서를 통해 측정된 외부온도를 제어부로 전송하고, 이때 측정된 실외온도가 기준 실외온도보다 낮아 "저온영역"에 해당하는지 판단하는 것이다. 기준 실외온도는 약 20℃를 기준으로 한다. 이에 한정하는 것은 아니다. 차량이 운행되는 환경에 따라 조정가능하다. 상기 기준 실외온도는 15 ~ 20℃ 임이 바람직하다.This is to transmit the external temperature measured through the outdoor temperature sensor to the controller, and at this time, it is determined whether the measured outdoor temperature is lower than the reference outdoor temperature to correspond to the "low temperature range". The reference outdoor temperature is based on about 20 ° C. It is not limited to this. It is adjustable according to the environment in which the vehicle is driven. The reference outdoor temperature is preferably 15 ~ 20 ℃.

상기 외기온도가 상기 기준 외기온도 이하이면, 차실내 온도가 기준 내기온도 이하인지를 판단하는 단계이다(S2).If the outside air temperature is less than or equal to the reference outside air temperature, it is a step of determining whether the interior temperature is less than or equal to the reference inside air temperature (S2).

이는, 인카센서를 통해 측정된 자동차의 실내온도를 제어부로 전송하고, 이때 측정된 실내온도가 기준 내기온도보다 낮아 "저온영역"에 해당하는지 판단하는 것이다. 기준 내기온도는 약 15℃를 기준으로 한다. 이에 한정하는 것은 아니다. 차량이 운행되는 환경에 따라 조정가능하다. 상기 기준 내기온도는 13 ~ 15℃ 임이 바람직하다.This is to transmit the indoor temperature of the vehicle measured by the in-car sensor to the control unit, and at this time, it is determined whether the measured indoor temperature is lower than the reference internal temperature to correspond to the "low temperature range". Standard betting temperature is based on about 15 ℃. It is not limited to this. It is adjustable according to the environment in which the vehicle is driven. The reference bet temperature is preferably 13 ~ 15 ℃.

상기 차실내 온도가 기준 내기온도 이하이면, 일사량이 기준 일사량 이하인지를 판단하는 단계이다(S3).If the vehicle interior temperature is equal to or less than the reference internal temperature, it is determined whether the amount of insolation is equal to or less than the reference insolation (S3).

이는, 일사량센서를 통해 측정된 변환 전압 값을 제어부로 전송하고, 이때 측정된 변환 전압 값이 기준 일사량보다 낮아 "저온영역"에 해당하는지 판단한다. 기준 일사량은 약 0.3V를 기준으로 한다. 이에 한정하는 것은 아니다. 차량이 운행되는 환경에 따라 조정가능하다. 상기 기준 일사량은 0.2 ~ 0.3V 임이 바람직하다.This transmits the converted voltage value measured through the solar radiation sensor to the controller, and determines whether the measured converted voltage value is lower than the reference solar radiation amount to correspond to the "low temperature region". Reference solar radiation is based on about 0.3V. It is not limited to this. It is adjustable according to the environment in which the vehicle is driven. The reference solar radiation is preferably 0.2 ~ 0.3V.

상기 일사량이 기준 일사량 이하이면, 냉각수온도가 기준 냉각수온도 이하인지를 판단하는 단계이다.If the amount of insolation is less than or equal to the reference insolation, it is a step of determining whether the cooling water temperature is lower than or equal to the reference cooling water temperature.

이는, 냉각수온센서를 통해 엔진에서 히터코어로 순환하는 냉각수의 측정된 냉각수온도를 제어부로 전송하고, 이때 측정된 냉각수온도가 기준 냉각수온도보다 낮아 "저온영역"에 해당하는지 판단한다.This transmits the measured coolant temperature of the coolant circulating from the engine to the heater core through the coolant temperature sensor to the controller, and determines whether the measured coolant temperature is lower than the reference coolant temperature to correspond to the "low temperature region".

또한, 저온영역의 냉각수온도의 변화에 따라 제1 및 제2기준온도, 또는 상기 제2기준온도보다 높을 경우에 따라서 토출모드 및 송풍기의 회전속도를 제어한다.In addition, the discharge mode and the rotational speed of the blower are controlled according to the change of the coolant temperature in the low temperature region or higher than the first and second reference temperatures or the second reference temperature.

상기 각 단계에서 조건을 모두 만족하는 경우에, 난방기동제어모드로 진입하는 단계이다(S5).When all of the conditions are satisfied in each of the above steps, the heating start control mode is entered (S5).

즉, 상기한 단계(S1 내지 S4)들의 모든 제어조건이 만족할 경우에, 제어부는 자동차용 공조장치를 "난방기동제어모드"로 변환시킨다.That is, when all the control conditions of the above-described steps (S1 to S4) are satisfied, the control unit switches the vehicle air conditioner to the "heating start control mode".

도 2에 도시된 바와 같이, 상기 난방기동제어모드는, 냉각수온도가 제1기준온도인 약 40 ~ 43℃ 범위일 경우에는, 디프로스트 벤트로 공기를 공급하는 디프로스트 모드이고, 송풍기의 회전속도는 저속으로 작동되어, 찬바람이 머리 쪽으로 송출되도록 한다.As shown in FIG. 2, the heating start control mode is a defrost mode for supplying air to the defrost vent when the coolant temperature is in the range of about 40 to 43 ° C., which is the first reference temperature, and the rotation speed of the blower. Is operated at low speed, allowing the cold wind to blow out towards the head.

즉, 난방기동제어 모드에서 냉각수온도가 제1기준온도 범위일 경우, 토출모드는 디프로스트 모드로 하고 송풍기의 풍력을 최소화함으로써, 머리 쪽으로 차가운 바람이 토출되도록 하여 탑승자 또는 운전자의 쾌적성을 향상시킬 수 있다.That is, in the heating start control mode, when the coolant temperature is within the first reference temperature range, the discharge mode is set to the defrost mode and the wind power of the blower is minimized, so that cool wind is discharged toward the head to improve the passenger or driver comfort. Can be.

또한, 냉각수온도가 제2기준온도인 약 43 ~ 46℃ 범위일 경우에는, 디프로스트 벤트 및 플로어 벤트로 공기를 공급하는 믹스모드이고, 송풍기의 회전속도는 중속으로 작동되어, 다소 따뜻한 바람이 머리 및 발 쪽으로 송출되도록 한다.In addition, when the coolant temperature is in the range of about 43 to 46 ° C., which is the second reference temperature, it is a mixed mode for supplying air to the defrost vent and the floor vent, and the rotational speed of the blower is operated at a medium speed so that a somewhat warm wind is generated. And to the foot.

또한, 냉각수온도가 제2기준온도 범위 이상일 경우에는, 플로어 벤트로 공기를 공급하는 플로어 모드이고, 송풍기의 회전속도는 고속으로 작동되어, 따뜻한 바람이 발 쪽으로 송출되도록 한다.In addition, when the coolant temperature is greater than or equal to the second reference temperature range, the floor is a floor mode for supplying air to the floor vent, and the rotation speed of the blower is operated at a high speed so that warm wind is sent out to the feet.

즉, 냉각수온도의 변화에 따라 토출모드 및 송풍기의 회전속도에 의한 풍력을 조절함으로써, 탑승자 또는 운전자의 쾌적성을 유지할 수 있다.That is, by adjusting the wind power according to the discharge mode and the rotational speed of the blower according to the change in the coolant temperature, it is possible to maintain the comfort of the occupant or driver.
