Description
본 발명은 자동차 냉난방장치 제어방법에 관한 것으로서, 더욱 상세하게는 냉난방장치 제어시 차량의 실내외간 온도차가 고려되는 바, 현재의 실내온도가 설정온도보다 일정수준 높아 냉방이 이루어져야 함에도 실내외간 온도차가 일정수준 이상이면 과도한 냉방으로 판단하여 냉방장치를 정지시켜주고, 현재의 실내온도가 설정온도보다 일정수준 이하여서 난방이 이루어져야 함에도 실내외간 온도차가 일정수준 이상이면 과도한 난방으로 판단하여 난방장치를 정지시켜줌으로써, 차량 실내의 과도한 냉방 또는 난방이 억제될 수 있고, 특히 과도한 냉방에 의한 엔진부하를 줄일 수 있어 연비를 향상시킬 수 있는 자동차 냉난방장치 제어방법에 관한 것이다.The present invention relates to a method for controlling a vehicle air conditioner, and more particularly, a temperature difference between indoors and outside of a vehicle is considered when controlling an air conditioner, and a temperature difference between indoors and outsides is constant even though the current indoor temperature is a certain level higher than a set temperature. If it is above the level, it is judged to be excessive cooling and stops the cooling system.If the current indoor temperature is below the set temperature and needs to be heated, if the temperature difference between indoor and outdoor is over a certain level, it is judged as excessive heating to stop the heating system. In particular, the present invention relates to a method for controlling a vehicle air conditioner that can suppress excessive cooling or heating of a vehicle interior, and in particular, can reduce an engine load caused by excessive cooling, thereby improving fuel efficiency.
일반적으로 차량에는 차량 실내를 적절히 냉방 또는 난방하여 차량의 실내온도를 쾌적하게 유지시켜주는 냉난방장치가 구비된다.In general, a vehicle is provided with a cooling and heating device that maintains the indoor temperature of the vehicle comfortably by appropriately cooling or heating the vehicle interior.
상기 냉난방장치는 다양한 기후조건이나 주행조건하에서도 운전자 및 승원에게 쾌적한 실내환경을 제공하기 위하여 구비되는 것으로서, 운전자나 승원이 희망하는 실내온도를 미리 설정하여 입력하게 되면 차량의 실내온도를 소정의 온도범위 이내에서 설정온도에 맞게 일정하게 유지시켜주도록 되어 있다.The air-conditioning and heating device is provided to provide a comfortable indoor environment to the driver and the crew even under various climatic conditions or driving conditions. It is kept to be consistent with the set temperature within the range.
첨부한 도 2에서는 종래의 냉난방장치 제어방법을 보여주고 있다.Figure 2 shows a conventional method of controlling a heating and cooling device.
우선, 운전자 또는 승원이 냉난방장치의 스위치를 온(on) 조작한 후 희망하는 실내온도(Tr)를 설정하여 입력하게 되면, 냉난방장치의 작동을 총괄 제어하는 컨트롤러는 차량 실내의 온도센서로부터 현재의 실내온도(Tin)를 입력받은 후, 이를 설정온도(Tr)와 비교하게 된다.First, when the driver or the crew turns on and turns on the air conditioner switch and inputs the desired room temperature (T r ), the controller which controls the operation of the air conditioner is controlled from the temperature sensor of the vehicle interior. After receiving the room temperature (T in ) of it, it is compared with the set temperature (T r ).
여기서, 상기 컨트롤러는 온도센서로부터 입력되는 현재의 실내온도(Tin)가 설정온도(Tr)보다 높고() 이 높은 정도가 소정의 온도차값(α)보다 크면(), 냉방장치를 작동시키게 된다.Here, the controller is the current room temperature (T in ) input from the temperature sensor is higher than the set temperature (T r ) ( If this high degree is larger than the predetermined temperature difference value α ( ), The air conditioner is activated.
반면, 상기 컨트롤러는 온도센서로부터 입력되는 현재의 실내온도(Tin)가 설정온도(Tr) 이하이고() 이 낮은 정도가 상기 온도차값(α)보다크면(), 난방장치를 작동시키게 된다.On the other hand, the controller is the current room temperature (T in ) input from the temperature sensor is less than the set temperature (T r ) ( Is less than the temperature difference value α, ), It turns on the heating system.
또한, 현재의 실내온도(Tin)가 설정온도(Tr)보다 높더라도() 이 높은 정도가 상기 온도차값(α) 이하이면(), 냉방장치를 정지시키게 된다.In addition, even if the current room temperature T in is higher than the set temperature T r ( If the degree to which this high degree is below the said temperature difference value (alpha) ( ), The cooling unit is stopped.
또한, 현재의 실내온도(Tin)가 설정온도(Tr) 이하일지라도() 이 낮은 정도가 상기 온도차값(α) 이하이면(), 난방장치를 정지시키게 된다.Further, even if the current room temperature T in is equal to or less than the set temperature T r ( If the low degree is less than or equal to the temperature difference value α ), The heating system is stopped.
위의 설명과 도 2에 나타낸 온도차값 α는 미리 입력된 값이다.The temperature difference value α shown in the above description and in FIG. 2 is a previously input value.
그러나, 상기와 같이 이루어지는 냉난방장치 제어방법에서는 차량의 실내온도를 차량의 실외온도와 무관하게 설정온도에만 맞추어 냉난방을 제어하기 때문에 과도한 냉방 또는 난방이 이루어질 수 있는 문제점이 있었다.However, there is a problem in that the cooling and heating apparatus control method is configured to control the cooling and heating by adjusting only the indoor temperature of the vehicle to the set temperature irrespective of the outdoor temperature of the vehicle, thereby causing excessive cooling or heating.
즉, 실외온도를 무시한 과도한 난방은 추운 겨울철에 두꺼운 옷을 입은 운전자나 승원들에게 더위를 느끼게 할 수 있고, 실외온도를 무시한 과도한 냉방은 더운 여름철에 반팔의 얇은 옷을 입은 운전자나 승원들에게 추위를 느끼게 할 수 있다.In other words, excessive heating ignoring the outdoor temperature may cause the driver or crew to wear thick clothes in the cold winter season, and excessive cooling ignoring the outdoor temperature may be cold for the driver or crew members wearing the short sleeve thin clothes in the hot summer season. Can make you feel.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서,냉난방장치 제어시 차량의 실내외간 온도차가 고려되는 바, 현재의 실내온도가 설정온도보다 일정수준 높아 냉방이 이루어져야 함에도 실내외간 온도차가 일정수준 이상이면 과도한 냉방으로 판단하여 냉방장치를 정지시켜주고, 현재의 실내온도가 설정온도보다 일정수준 이하여서 난방이 이루어져야 함에도 실내외간 온도차가 일정수준 이상이면 과도한 난방으로 판단하여 난방장치를 정지시켜줌으로써, 차량 실내의 과도한 냉방 또는 난방이 억제될 수 있고, 특히 과도한 냉방에 의한 엔진부하를 줄일 수 있어 연비를 향상시킬 수 있는 자동차 냉난방장치 제어방법을 제공하는데 그 목적이 있다.Therefore, the present invention has been invented to solve the above problems, the temperature difference between the indoor and outdoor of the vehicle is considered when the air conditioner is controlled, the temperature difference between the indoor and outdoor, even if the current indoor temperature is a certain level higher than the set temperature to be cooled If it is over a certain level, it is judged to be excessive cooling and stops the cooling system.If the current indoor temperature is below a certain level and needs to be heated, if the temperature difference between indoor and outdoor is over a certain level, it is judged as excessive heating to stop the heating system. By providing a vehicle, an excessive cooling or heating of a vehicle interior can be suppressed, and in particular, an engine load caused by excessive cooling can be reduced, and an object of the present invention is to provide a vehicle air conditioner control method which can improve fuel efficiency.
