카에어컨 제어방법Car air conditioner control method

본 발명은 에어컨 제어에 관한 것으로, 특히 실내온도에 따라 에어컨의 구동을 제어할 수 있도록 하는 카에어컨 제어방법에 관한 것이다.The present invention relates to air conditioner control, and more particularly, to a car air conditioner control method for controlling the operation of the air conditioner according to the room temperature.

일반적으로 차량에는 대부분 에어컨이 탑재되어 자동차 실내를 공조하여 쾌적한 환경을 유지시키게 된다.In general, most of the vehicles are equipped with air conditioning to maintain a comfortable environment by air conditioning the interior of the car.

이러한 에어컨은 엔진의 회전을 동력원으로 하기 때문에 여름철 주행시 엔진에 무리한 과부하로 작용할 수 있어, 필요치 않는 냉방을 자제하는 것이 차량 주행상태를 원활히 할 수 있는 것이다.Since the air conditioner uses the rotation of the engine as a power source, the air conditioner may act as an excessive load on the engine during summer driving, and refraining from unnecessary cooling may smoothly drive the vehicle.

그러나 종래 에어컨은 운전자가 필요에 의해 직접 조작하도록 함으로써 실내온도를 정확히 유지하기 어려웠을 뿐만 아니라 주행상태가 양호하지 못한 문제점이 있었다.However, the conventional air conditioner has a problem that not only it is difficult to maintain the room temperature accurately by allowing the driver to directly operate as needed, but also the driving condition is not good.

본 발명은 이러한 점을 감안하여 안출된 것으로, 특히 실내온도에 따라 에어컨을 자동으로 제어되게 함으로써 실내를 쾌적하게 유지하고 아울러 엔진에 걸리는 부하량을 감소시킬 수 있도록 하는 카에어컨 제어방법을 제공하는데 목적이 있다.The present invention has been made in view of this point, and in particular, an object of the present invention is to provide a car air conditioner control method that allows the air conditioner to be automatically controlled according to the room temperature, thereby keeping the room comfortable and reducing the load on the engine. have.

이러한 목적을 달성하기 위한 본 발명의 카에어컨 제어방법은 실내온도를 검출하는 실온센서로 부터 입력된 신호를 근거로 에어컨을 제어하는 마이컴이 구비된 에어컨 제어방법에 있어서, 실내온도가 설정온도 보다 높고 배터리 전압이 설정전압 이상일 경우 에어컨을 구동시키며, 반대로 실내온도가 설정온도 보다 높고 배터리 전압이 설정전압보다 낮을 경우 에어컨을 정지시키도록 함을 특징으로 한다.Car air conditioner control method of the present invention for achieving this object in the air conditioner control method equipped with a microcomputer to control the air conditioner based on a signal input from the room temperature sensor for detecting the room temperature, the room temperature is higher than the set temperature The air conditioner is driven when the battery voltage is higher than the set voltage. On the contrary, the air conditioner is stopped when the room temperature is higher than the set temperature and the battery voltage is lower than the set voltage.

이러한 방법에 의하면, 본 발명은 차량의 실내온도를 적정하게 유지할 수 있고 에어컨 구동중 배터리전압이 낮아지면 자동으로 정지시켜 엔진에 걸리는 과부하를 해소하게 된다.According to this method, the present invention can properly maintain the indoor temperature of the vehicle, and automatically stops when the battery voltage decreases while driving the air conditioner, thereby overloading the engine.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 통해 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 블록회로도써, 자동차 실내온도를 감지하는 실온센서(10)와, 상기 실온센서에서 감지된 신호를 기준신호와 비교하여 에어컨 구동 여부를 판단하는 마이컴(20)과, 상기 마이컴의 제어신호에 의해 에어컨을 구동하는 에어컨 구동부(30)로 구성된다.1 is a block circuit diagram according to the present invention, a room temperature sensor 10 for detecting a vehicle interior temperature, a microcomputer 20 for determining whether to drive an air conditioner by comparing a signal detected by the room temperature sensor with a reference signal, and An air conditioner driver 30 for driving the air conditioner by the control signal of the microcomputer.

이하, 상기한 실시예 구성에 따른 에어컨 제어방법을 상세하게 설명하면, 본 발명은 운전자가 실내온도를 설정하거나 또는 마이컴(20)에서 인체에 적합한 온도로 설정된 기준온도와 실온센서(10)에서 검출된 실내온도를 비교하여 에어컨 구동여부를 판단하게 된다.Hereinafter, the air conditioner control method according to the above-described embodiment configuration in detail, the present invention the driver sets the room temperature or the microcomputer 20 detects the reference temperature and room temperature sensor 10 is set to a temperature suitable for the human body It is determined whether the air conditioner is driven by comparing the indoor temperature.

즉, 실내온도가 설정된 기준온도 보다 높을 경우 마이컴(20)에서는 현재의 배터리 전압상태를 판단하고, 만약 배터리 전압이 설정전압(12V) 보다 높을 경우 에어컨을 구동시키며, 반대로 배터리 전압이 설정전압 보다 낮을 경우에는 엔진에 과부하가 걸린 것으로 판단하고 실내온도가 설정온도 보다 높음에도 불구하고 에어컨 구도부(30)에 인가되는 전원을 차단하여 정지시켜 차량 주행상태를 안정시키게 된다.That is, when the indoor temperature is higher than the set reference temperature, the microcomputer 20 determines the current battery voltage state, and if the battery voltage is higher than the set voltage (12V), the air conditioner is driven, and conversely, the battery voltage is lower than the set voltage. In this case, it is determined that the engine is overloaded, and even though the indoor temperature is higher than the set temperature, the vehicle is stabilized by cutting off and stopping the power applied to the air conditioner composition unit 30.

이상에서 설명한 바와 같이 본 발명은 실내온도와, 배터리전압을 기준값과 비교하여 판단하여 에어컨 구동여부를 결정하도록 함으로써 실내온도를 항상 쾌적하게 유지함과 동시에 엔진에 과부하가 걸릴 경우 에어컨을 정지시켜 차량 주행상태를 안정시키게 된다.As described above, the present invention compares the indoor temperature and the battery voltage with a reference value to determine whether to operate the air conditioner, thereby keeping the indoor temperature comfortable at all times and stopping the air conditioner when the engine is overloaded. To stabilize.
