Description

차량의 액티브 에어 플랩 제어 시스템 및 방법{SYSTEM FOR CONTROLLING ACTIVE AIR FLAP IN VEHICLE AND METHOD THEREOF}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active air flap control system for a vehicle,

본 발명은 차량의 액티브 에어 플랩 제어 시스템 및 방법에 관한 것으로, 더 상세하게는 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 한 차량의 액티브 에어 플랩 제어 시스템 및 방법에 관한 것이다.
The present invention relates to an active air flap control system and method for a vehicle, and more particularly, to an active air flap control system and method for a vehicle that can open and close a flap within a motor torque upper limit value taking into account the speed and wind speed / .

일반적으로 플랩 제어 시스템은 차량의 라디에이터 그릴과 라디에이터 사이에 개폐가 가능한 플랩을 장착하여 제어하는 시스템이다.Generally, the flap control system is a system for controlling by mounting a flap capable of opening and closing between a radiator grill of a vehicle and a radiator.

이러한 플랩 제어 시스템은 차량의 고속 주행시 플랩을 폐쇄함으로써 차량의 공기 저항을 감소시켜 주행 안정성 향상을 도모한다.Such a flap control system reduces the air resistance of the vehicle by closing the flap at the time of driving the vehicle at a high speed, thereby improving driving stability.

또한, 엔진 룸 내부의 온도가 상승하여 부품이 과열될 우려가 있을 경우에는 플랩을 개방하여 엔진 룸 내부 온도를 낮추는 기능을 수행한다. 이를 위해서는 차속 뿐만 아니라, 냉각수온도, 모터 온도, 오일 온도 등 차량의 상태에 대한 신호를 받아 플랩을 개폐한다.Further, when the temperature inside the engine room rises and there is a possibility of overheating the parts, the flap is opened to lower the internal temperature of the engine room. In order to do this, the flap is opened and closed in response to signals of the vehicle condition such as the cooling water temperature, the motor temperature, and the oil temperature as well as the vehicle speed.

상기한 기술구성은 본 발명의 이해를 돕기 위한 배경기술로서, 본 발명이 속하는 기술분야에서 널리 알려진 종래기술을 의미하는 것은 아니다.
The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

종래의 플랩 제어는 액츄에이터를 구동하는 모터 토크를 기준으로 차속의 상한값을 두고 제어를 하고 있다.Conventional flap control controls the upper limit value of the vehicle speed based on the motor torque for driving the actuator.

이는 풍향과 풍속을 고려하지 않고 차속의 상한값만으로 플랩을 제어함으로써 차량의 방향과 반대의 맞바람이 불때는 예측불허의 상황으로 인해 플랩이 열리지 않고 구속되는 현상이 발생할 수 있다.This is because the flap is controlled only by the upper limit value of the vehicle speed without taking into consideration the wind direction and the wind speed, and when the wind head opposite to the direction of the vehicle is turned on, the flap may not be opened or restrained due to the unpredictable situation.

따라서, 본 발명은 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 한 차량의 액티브 에어 플랩 제어 시스템 및 방법을 제공하는데 그 목적이 있다.
Accordingly, it is an object of the present invention to provide an active air flap control system and method of a vehicle that can open and close a flap within a motor torque upper limit value considering a speed of a vehicle and a wind speed / direction.

그리고, 본 발명에 의한 차량의 액티브 에어 플랩 제어 방법은, 풍향과 풍속에 따른 차속 보정값을 연산하는 단계; 차량의 속도에 상기 차속 보정값을 반영한 보정속도가 제1기준속도 이하이고, 제2기준속도 이상이면 플랩을 오픈 구동하는 단계; 상기 보정속도가 상기 제2기준속도 미만이고, 제3기준속도를 초과하면 상기 플랩을 온도에 따라 제어하는 단계; 및 상기 보정속도가 상기 제3기준속도 이하이면 상기 플랩을 클로즈 구동하는 단계를 포함하는 것을 특징으로 한다.According to another aspect of the present invention, there is provided an active air flap control method for a vehicle, comprising: calculating a vehicle speed correction value according to a wind direction and a wind speed; Opening the flap if the correction speed reflecting the vehicle speed correction value to the vehicle speed is equal to or lower than the first reference speed and equal to or higher than the second reference speed; Controlling the flap according to the temperature when the correction speed is less than the second reference speed and exceeds a third reference speed; And closing the flap when the correction speed is equal to or lower than the third reference speed.

본 발명에서, 상기 보정속도가 상기 제1기준속도를 초과하면 경고등을 온 표시하는 것을 특징으로 한다.
In the present invention, the warning lamp is turned on when the correction speed exceeds the first reference speed.

상술한 바와 같이, 본 발명은 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 함으로써 고풍속/맞바람의 경우 플랩이 오픈되지 않는 치명적인 오류를 방지할 수 있다.
As described above, according to the present invention, it is possible to open and close the flap within the motor torque upper limit value considering the speed of the vehicle and the wind speed / direction of the vehicle, thereby preventing a fatal error that the flap is not opened in the case of high wind speed / wind.

이하, 실시예를 통하여 본 발명을 더욱 상세히 설명하기로 한다. 이들 실시예는 단지 본 발명을 예시하기 위한 것이며, 본 발명의 권리 보호 범위가 이들 실시예에 의해 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

이 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로, 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

도 1은 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 시스템의 구성을 설명하기 위한 블럭도이다.1 is a block diagram for explaining a configuration of an active air flap control system of a vehicle according to an embodiment of the present invention.

도 1을 참고하면, 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 시스템은 차속 감지부(1)와, 풍향/풍속 감지부(2)와, 온도 감지부(3)와, 제어부(4)와, 플랩 구동부(5)를 포함한다.Referring to FIG. 1, an active air flap control system for a vehicle according to an embodiment of the present invention includes a vehicle speed sensing unit 1, a wind direction / wind speed sensing unit 2, a temperature sensing unit 3, 4, and a flap driving unit 5.

차속 감지부(1)는 차량의 속도를 감지한다.The vehicle speed sensing portion 1 senses the speed of the vehicle.

풍향/풍속 감지부(2)는 차량 주행시 풍향과 풍속을 감지한다.The wind direction / wind speed sensing unit (2) senses wind directions and wind speeds when the vehicle is traveling.

온도 감지부(3)는 차량 내부의 냉각수와 오일과 모터 등의 온도를 감지한다.The temperature sensing unit 3 senses the temperatures of the cooling water, the oil and the motor in the vehicle.

제어부(4)는 차량의 속도와 풍향과 풍속에 따라 플랩 개폐를 제어한다. 이러한 제어부(4)는 풍향과 풍속에 따른 차속 보정값(VS_CompenWV)을 연산하고, 차량의 속도에 차속 보정값(VS_CompenWV)을 반영한 보정속도(차속+VS_CompenWV)에 따라 플랩 개폐를 제어한다.The control unit 4 controls flap opening and closing in accordance with the speed, the wind direction and the wind speed of the vehicle. The control unit 4 calculates a vehicle speed correction value VS_CompenWV according to the wind direction and the wind speed and controls the flap opening and closing according to the correction speed (vehicle speed + VS_CompenWV) reflecting the vehicle speed correction value VS_CompenWV to the vehicle speed.

플랩 구동부(5)는 제어부(4)의 제어에 따라 플랩을 개폐한다.The flap driving unit 5 opens and closes the flap under the control of the control unit 4. [

보다 구체적으로 설명하면, 제어부(4)는 차속 감지부(1)와 풍향/풍속 감지부(2)로부터 검출된 차량의 속도와 풍향/풍속을 입력받는다. 이는 차체의 프런트에 위치한 플랩이 외부적인 요인에 의해 직접적인 영향을 미치게 되는 인자이다.More specifically, the control unit 4 receives the vehicle speed and direction / wind speed detected from the vehicle speed sensing unit 1 and the direction / wind speed sensing unit 2. This is a factor that directly affects the flap located at the front of the car body by external factors.

이러한 제어부(4)는 풍향과 풍속에 따른 차속 보정값(VS_CompenWV)을 차량의 속도에 반영한 보정속도(차속+VS_CompenWV)가 플랩 구동용 모터 토크 최대치와 상응되는 속도(VS_SafetyMaxTorque) 이하일 때 플랩 개폐 제어를 수행한다. 차량이 저속 주행일 때는 온도에 따라 플랩 개폐를 제어한다.When the correction speed (vehicle speed + VS_CompenWV) reflecting the vehicle speed correction value VS_CompenWV according to the wind direction and the wind speed is equal to or lower than the speed VS_SafetyMaxTorque corresponding to the motor torque maximum value for the flap driving, the controller 4 controls the flap opening / . When the vehicle is traveling at low speed, the flap opening / closing is controlled according to the temperature.

다음으로, 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 방법을 설명하면 다음과 같다. 도 2는 본 발명의 일 실시예에 따른 차량의 액티브 에어 플랩 제어 방법을 설명하기 위한 순서도이다.Next, an active air flap control method of a vehicle according to an embodiment of the present invention will be described. 2 is a flowchart illustrating a method of controlling an active air flap of a vehicle according to an embodiment of the present invention.

도 2를 참고하면, 먼저 풍향과 풍속을 입력받아 풍향과 풍속에 따른 차속 보정값(VS_CompenWV)을 연산한다(S1).Referring to FIG. 2, the wind direction and the wind speed are input to calculate a vehicle speed correction value VS_CompenWV according to the wind direction and the wind speed (S1).

그리고, 차량의 속도에 차속 보정값(VS_CompenWV)을 반영한 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque)를 초과하는지 비교한다(S2).Then, it is determined whether the correction speed (vehicle speed + VS_CompenWV) reflecting the vehicle speed correction value VS_CompenWV exceeds the first reference speed VS_MaxTorque (S2).

여기서, 제1기준속도(VS_MaxTorque)는 무풍속/무풍향 조건시 플랩 구속현상을 발생시키지 않고 개폐 가능한 차속, 즉 플랩 구동용 모터 토크 최대치와 상응하는 속도이다.Here, the first reference speed VS_MaxTorque is a speed corresponding to the vehicle speed at which the flap restraint phenomenon does not occur in the non wind speed / no wind direction condition, that is, the motor torque maximum value for the flap drive.

이때, 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque) 이하이면 보정속도(차속+VS_CompenWV)가 제2기준속도(VS_SafetyMaxTorque) 이상인지 비교한다(S3)At this time, if the correction speed (vehicle speed + VS_CompenWV) is equal to or less than the first reference speed VS_MaxTorque, the correction speed (vehicle speed + VS_CompenWV) is compared with the second reference speed VS_SafetyMaxTorque (S3)

여기서, 제2기준속도(VS_SafetyMaxTorque)는 무풍속/무풍향 조건시 플랩 구속현상을 발생시키지 않고 개폐 가능한 제1기준속도(VS_MaxTorque)에서 안전을 위한 소정 값을 뺀 속도이다.Here, the second reference speed (VS_SafetyMaxTorque) is a speed obtained by subtracting a predetermined value for safety from a first reference speed (VS_MaxTorque) that can be opened and closed without causing a flap restraint phenomenon in no wind speed / no wind direction condition.

보정속도(차속+VS_CompenWV)가 제2기준속도(VS_SafetyMaxTorque) 이상이면 플랩을 오픈 구동한다(S4).If the correction speed (vehicle speed + VS_CompenWV) is equal to or higher than the second reference speed VS_SafetyMaxTorque, the flap is driven open (S4).

즉, 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque) 이하이고, 제2기준속도(VS_SafetyMaxTorque) 이상이면 플랩을 오픈 구동한다.That is, if the correction speed (vehicle speed + VS_CompenWV) is equal to or less than the first reference speed (VS_MaxTorque) and equal to or higher than the second reference speed (VS_SafetyMaxTorque), the flap is open-driven.

이어서, 보정속도(차속+VS_CompenWV)와 제3기준속도(VS_SafetyMaxTorque-HYS)를 비교한다(S5).Subsequently, the correction speed (vehicle speed + VS_CompenWV) is compared with the third reference speed VS_SafetyMaxTorque-HYS (S5).

여기서, 제3기준속도(VS_SafetyMaxTorque-HYS)는 플랩의 빈번한 개폐 방지를 위해 히스테리시스 값(Hystersis value)을 뺀 속도이다.Here, the third reference speed VS_SafetyMaxTorque-HYS is a speed obtained by subtracting the hysteresis value (Hysteresis value) to prevent the flap from frequently opening and closing.

보정속도(차속+VS_CompenWV)가 제3기준속도(VS_SafetyMaxTorque-HYS) 이하이면 플랩을 클로즈 구동한다(S6).When the correction speed (vehicle speed + VS_CompenWV) is equal to or less than the third reference speed VS_SafetyMaxTorque-HYS, the flap is driven close (S6).

그리고, 보정속도(차속+VS_CompenWV)가 제1기준속도(VS_MaxTorque)를 초과하면 경고등을 온 한다(S7).When the correction speed (vehicle speed + VS_CompenWV) exceeds the first reference speed VS_MaxTorque, the warning lamp is turned on (S7).

또한, 보정속도(차속+VS_CompenWV)가 제2기준속도(VS_SafetyMaxTorque) 미만이고, 제3기준속도(VS_SafetyMaxTorque-HYS)를 초과하면 플랩을 온도에 따라 제어한다(S8).If the correction speed (vehicle speed + VS_CompenWV) is less than the second reference speed VS_SafetyMaxTorque and exceeds the third reference speed VS_SafetyMaxTorque-HYS, the flap is controlled according to the temperature (S8).

온도에 따른 제어는 냉각수 온도와 오일온도와 모터 온도와 등의 온도가 외기온도에 따라 달라지는 기준온도 초과시 플랩을 개방하고, 기준온도 이하일 때는 플랩을 클로즈 한다.Temperature-dependent control opens the flap when the coolant temperature, the oil temperature, the motor temperature, etc., exceed the reference temperature, which depends on the ambient temperature. When the temperature is below the reference temperature, the flap is closed.

이와 같이, 본 발명은 차량의 속도와 풍속/풍향을 고려한 모터 토크 상한값 이내에서 플랩을 개폐할 수 있도록 함으로써 고풍속/맞바람의 경우 플랩이 오픈되지 않는 치명적인 오류를 방지할 수 있다.As described above, according to the present invention, it is possible to open and close the flap within the motor torque upper limit value considering the speed of the vehicle and the wind speed / direction of the vehicle, thereby avoiding a fatal error that the flap is not opened in the case of high wind speed / wind.
