Description

차속에 따른 냉각 팬 작동 제어 방법How to control cooling fan operation according to vehicle speed

본 발명은 일정 차속을 기준으로 냉각 팬(Cooling Fan)의 작동여부가 단속되도록 하는 차속에 따른 냉각 팬 작동 제어 방법에 대한 것이다.The present invention relates to a cooling fan operation control method according to the vehicle speed to the operation of the cooling fan (Cooling Fan) based on a certain vehicle speed.

일반적으로 자동차에 구비되는 냉각 팬에는 냉각수를 외기에 의해서 강제로 열교환시키게 되는 라이에이터 팬(Radiator Fan)과 에어컨 냉매를 열교환시키게 되는 콘덴서 팬(Condenser Fan)이 있다.In general, a cooling fan provided in an automobile includes a radiator fan for forcibly exchanging coolant by external air and a condenser fan for exchanging air conditioner refrigerant.

이같은 냉각 팬은 통상 냉각수온에 따라서 전자 제어 장치(ELECTRONIC CONTROL UNIT, 이하 ECU로 약칭함)에 의해 작동이 단속제어되도록 하고 있는바 현재는 도 2 에서와 같은 방법으로 제어를 하도록 하고 있다.Such a cooling fan is controlled to be intermittently controlled by an electronic controller (ELECTRONIC CONTROL UNIT, hereinafter called ECU) in accordance with the cooling water temperature. Currently, the cooling fan is controlled as shown in FIG.

즉 에어컨이 작동 중일 때는 라디에이터 팬이나 콘덴서 팬은 무조건 작동이 되나 에어컨이 미작동시에는 라디에이터 팬과 콘덴서 팬은 냉각수온 센서에서 감지되는 냉각수의 온도에 따라서 작동 여부가 결정된다.In other words, when the air conditioner is in operation, the radiator fan or condenser fan is operated unconditionally. When the air conditioner is not in operation, the radiator fan and the condenser fan are operated according to the temperature of the coolant detected by the coolant temperature sensor.

따라서 에어컨이 미작동상태에서 냉각수온이 95℃ 이상이면 라디에이터 팬이 작동 온(ON)되고, 90℃ 미만에서는 작동 오프(OFF)되며, 105℃ 이상에서는 콘덴서 팬이 작동 온되고, 100℃ 미만에서는 작동 오프되는 방법으로 작동이 제어된다.Therefore, when the coolant temperature is 95 ℃ or higher while the air conditioner is inactive, the radiator fan is turned on, below 90 ℃, the condenser fan is turned on above 105 ℃, and below 100 ℃. Operation is controlled in such a way that operation is off.

하지만 기존의 냉각 팬 설계 기준은 대단히 차속이 저속인 상태에서 차량 냉각계가 과열되지 않도록 하는 수준에서 팬 구동에 따른 냉각 효율을 산출하고 있는바 실제적으로는 도 3 에서와 같이 차속이 일정 속도, 약 90km 이상에서는 차량 주행시의 풍력이 냉각 팬 구동시의 풍력을 상회하게 되므로서 냉각 팬에 의한 냉각 효율은 극히 저조할 뿐만 아니라 도리어 냉각 팬 구동이 주행 풍력에 방해가 되면서 대단히 시끄러운 소음과 함께 진동을 유발시키게 되는 문제점이 있다.However, the existing cooling fan design standard calculates the cooling efficiency according to the fan driving at a level that prevents the vehicle cooling system from overheating at a very low speed. Actually, as shown in FIG. 3, the speed of the vehicle is about 90 km. In the above, since the wind speed of driving the vehicle exceeds the wind speed of driving the cooling fan, the cooling efficiency by the cooling fan is extremely low, and the cooling fan driving interferes with the driving wind, causing vibration with very loud noise. There is a problem.

본 발명은 상기한 문제점을 감안하여 이를 간단하게 개선시키기 위한 것으로서 이에 본 발명은 일정 차속을 기준으로 그보다 느린 속도에서는 종전과 동일한 방법으로 냉각 팬을 구동시키게 되나 그보다 빠른 속도에서는 무조건 냉각 팬 구동이 정지되도록 하여 불필요한 냉각 팬 구동을 방지시키므로서 팬 구동 손실을 예방하고, 고속 주행시의 팬 구동에 따른 진동과 소음이 대폭 저감될 수 있도록 하는 차속에 따른 냉각 팬 작동 제어 방법을 제공코자 하는데 목적이 있다.The present invention is to simply improve in view of the above problems, the present invention is to drive the cooling fan in the same way as before at a slower speed based on a constant vehicle speed, but at a higher speed unconditionally cooling fan drive is stopped The purpose of the present invention is to provide a cooling fan operation control method according to a vehicle speed to prevent fan driving loss by preventing unnecessary cooling fan driving, and to significantly reduce vibration and noise due to fan driving at high speed.

상기한 목적을 달성시키기 위하여 본 발명은 에어컨이 작동중에는 작동 온되고, 에어컨이 미작동시에는 냉각수온에 따라 작동이 제어되는 냉각 팬 작동 제어구조에 있어서, 주행 차속이 기설정한 일정 차속보다 빠르다고 판단되면 그즉시 팬 구동을 작동 오프시키므로서 주행풍력에 의해 냉각작용이 수행되도록 하는 것이 가장 두드러진 특징이다.In order to achieve the above object, the present invention provides a cooling fan operation control structure in which the air conditioner is turned on while the air conditioner is in operation and the air conditioner is controlled according to the coolant temperature when the air conditioner is not in operation. The most prominent feature is that the cooling operation is performed by the driving wind power by turning off the fan drive immediately.

도 2 는 종래의 냉각 팬 제어 도표2 is a conventional cooling fan control diagram

도 3 은 차속 및 냉각 팬에 의핸 방열 효과의 비교선도3 is a comparative diagram of the heat dissipation effect by the vehicle speed and cooling fan

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면 도 1 은 본 발명에 따른 제어 도표를 도시한 것이다.Referring to this in more detail with reference to the accompanying drawings, Figure 1 shows a control diagram according to the present invention.

상기한 도표에서와 같이 본 발명은 종전과 같이 냉각 팬을 에어컨이 작동상태 및 냉각수온에 의해서 구동이 제어되면서 동시에 차속에 의해서도 제어될 수 있도록 하는 것이다.As shown in the above diagram, the present invention allows the cooling fan to be controlled by the vehicle speed at the same time while the air conditioner is controlled by the operating state and the cooling water temperature.

즉, ECU내에 기설정한 일정 차속(VS) 이내에서는 에어컨이 작동시 냉각 팬은 종전과 같이 무조건 작동 온상태가 되고, 에어컨이 미작동시에는 냉각수온에 따라서 작동이 제어된다.That is, within the predetermined vehicle speed (V S ) set in the ECU, the cooling fan is turned on unconditionally as before when the air conditioner is operated. When the air conditioner is not operated, the operation is controlled according to the cooling water temperature.

그리고 주행 차속(VC)이 기설정한 일정 차속(VC)을 벗어나게 되면 냉각 팬은 에어컨작동에 관계없이 무조건 작동 오프상태가 되도록 한다.Then, when the running vehicle speed (V C) off a predetermined vehicle speed (V C) is set is a group cooling fan is such that the unconditional operation OFF state, regardless of the air-conditioning operation.

이같은 냉각 팬 구동은 차속이 일정 속도 이하에서 에어컨을 가동하게 되면 냉각 팬은 무조건 구동을 하지만 에어컨이 미작동시에는 기설정된 냉각수온에 따라 라디에이터 팬과 콘덴서 팬을 선택적으로 작동시키게 되는바 이러한 상태에서 차속(VC)이 일정 이상으로 증속되면 그즉시 냉각 팬 구동이 정지되면서 이때부터는 주행 풍력에 의해 냉각작용이 수행될 수 있도록 한다.In this case, the cooling fan runs unconditionally when the vehicle speed is below a certain speed. However, when the air conditioner is not running, the radiator fan and the condenser fan are selectively operated according to the preset cooling water temperature. If (V C ) is increased beyond a certain level, the cooling fan is stopped immediately, and the cooling operation can be performed by the driving wind from this time.

특히 상기와 같은 냉각 팬 구동을 중지시키기 위한 기준이 되는 주행 차속(VS)은 주행 풍력이 냉각 팬에 의한 방열 효과를 앞지르게 되는 약 90∼100km/H로서 설정되도록 하는 것이 가장 바람직하다.In particular, it is most preferable that the traveling vehicle speed V S as a reference for stopping the driving of the cooling fan is set to about 90 to 100 km / H, in which the traveling wind power is ahead of the heat radiating effect by the cooling fan.

따라서 상기와 같은 냉각 팬 구동 제어시 일정 차속(VS) 이상에서는 냉각 팬 구동이 정지되면서 주행 풍력에 의해 원활하게 라디에이터와 콘덴서를 냉각시키게 되므로서 냉각 팬에 의해 냉각할 때보다는 더욱 냉각 효율을 상승시키게 된다.Therefore, cooling fans, such as the drive control when a certain vehicle speed (V S) at least in the rising more cooling efficiency rather than to cooling by standing in the cooling fan, so thereby smoothly cool the radiator and condenser by running wind while the cooling fan drive stop Let's go.

그러므로 본 발명에 따라 고속 주행시 냉각 팬을 구동시키게 되므로서 초래하게 되는 동력 손실과 소음 및 진동을 저감시킬 수가 있게 되어 보다 안정되고 정숙한 주행감과 함께 냉각팬의 내구력을 향상시키게 되는 매우 유용한 효과를 제공하게 되는 것이다.Therefore, according to the present invention, it is possible to reduce the power loss, noise and vibration caused by driving the cooling fan at high speed, thereby providing a very useful effect of improving the durability of the cooling fan with a more stable and quiet running feeling. Will be done.
