Abstract

차량의 전방 좌, 우측에 설치되어, 주변의 풍속을 감지한 뒤에 이를 전기적인 신호로 변환하여 출력하는 좌측 및 우측 풍속센서(10,20)와, 운전자에 의하여 에어로 디바이스 기능이 선택될 경우에, 이를 감지한 뒤에 전기적인 신호로 변환하여 출력하는 선택 스위치(SSW)와, 상기 선택 스위치가 온 되면, 상기 좌, 우측 풍속센서로부터 입력되는 신호를 이용하여 풍속을 감지하고, 감지된 풍속으로부터 요잉모멘트가 기준치 이상으로 발생되었는지를 판단하여, 요잉 모멘트가 발생된 경우에 에어로 디바이스를 구동하고, 요잉 모멘트가 발생되지 않은 경우에 에어로 디바이스를 원위치로 회복시키기 위한 제어신호를 출력하는 마이크로 컨트롤러(30)와, 프로그램 및 각종 변수가 저장되는 메모리(40)와, 상기 마이크로 컨트롤러로부터 입력되는 제어신호에 따라, 모터의 구동에 필요한 레벨의 신호를 생성하여 출력하는 모터 구동부(50)와, 모터 구동부로부터 입력되는 신호에 따라 정, 역회전되는 모터(60)와, 모터로부터 전달되는 회전동력을 이용하여 에어로 디바이스를 개폐시키는 에어로 디바이스 구동부로 구성되어, 차체의 측면에 에어로 디바이스를 설치하여 바람에 의한 압력의 발생을 저감시킴으로써 요잉 모멘트의 발생을 최소화시킬 수 있는 자동차의 요잉 모멘트 저감을 위한 에어로 디바이스 구동장치 및 그 방법에 관한 것.When the aero device function is selected by the driver, the left and right wind speed sensors 10 and 20 are installed at the front left and right sides of the vehicle and detect the surrounding wind speed and then convert it into an electrical signal. After detecting this, a selection switch (SSW) for converting and outputting an electric signal and when the selection switch is turned on, senses the wind speed by using signals input from the left and right wind speed sensors, and yawing moment from the detected wind speed. Microcontroller 30 for determining whether or not is generated above the reference value, driving the aero device when the yawing moment is generated, and outputting a control signal for returning the aero device to the home position when the yawing moment is not generated; And memory 40 storing programs and various variables and control signals input from the microcontroller. , By using the motor driver 50 for generating and outputting a signal having a level required for driving the motor, the motor 60 which is rotated forward and backward according to the signal input from the motor driver, and the rotational power transmitted from the motor. An aero device driving unit configured to open and close the device, the aero device driving device for reducing the yawing moment of a vehicle which can minimize the generation of the yawing moment by installing an aero device on the side of the vehicle body and reducing the generation of the pressure caused by the wind; About that method.
