Abstract

운전자가 브레이크의 동작을 자동으로 할 것인지, 아니면 수동으로 할 것인지를 선택하여 온/오프시키는 경우에 이를 전기적인 신호로 변환하여 출력하는 선택 스위치(SW)와; 전방 물체의 거리를 감지하기 위하여 광신호를 출력하고, 전방 물체에 의해 반사된 광신호를 감지하여 이를 전기적인 신호로 변환한 뒤에 출력하는 발광 소자(10) 및 수광 소자(20)와; 차량의 현재 속력을 감지하여 이를 전기적인 신호로 변환한 뒤에 출력하는 차속 센서(30)와; 선택 스위치가 온될 경우에, 수광 소자로부터 입력되는 신호로부터 전방 물체가 기준치보다 근거리에 있는지를 판단하고, 전방 물체가 기준치보다 근거리에 있는 경우에 차속 센서로부터 입력되는 신호로부터 현재 자동차의 속력이 고속 상태에 있는지를 판단하여, 이에 따라 브레이크를 자동으로 구동하기 위한 구동신호를 출력하는 제어부(40)와; 제어부로부터 입력되는 구동신호에 따라 푸트 브레이크 페달을 동작시키는 브레이크 구동부(50)로 구성되어; 전방에 물체가 있을 경우에 전방 물체의 거리와 차량의 속도를 종합적으로 판단하여 브레이크를 자동으로 동작시킴으로써 불의의 사고를 미연에 방지할 수 있고, 리니어 모터와 전자석을 이용하여 브레이크 페달을 구동시킴으로써 설치비용을 최소화시킬 수 있는 자동차의 브레이크 자동 제어장치 및 방법에 관한 것.A selection switch (SW) for converting and outputting an electric signal when the driver selects whether to operate the brake automatically or manually; A light emitting device 10 and a light receiving device 20 for outputting an optical signal to detect the distance of the front object, and detecting the optical signal reflected by the front object and converting the light signal into an electrical signal; A vehicle speed sensor 30 which detects a current speed of the vehicle and converts it into an electrical signal and then outputs the converted electrical signal; When the selection switch is turned on, it is determined whether the front object is closer than the reference value from the signal input from the light receiving element, and the speed of the current vehicle is high speed from the signal input from the vehicle speed sensor when the front object is closer than the reference value. And a control unit 40 for determining whether it is in the control unit and outputting a driving signal for automatically driving the brake accordingly; A brake driving unit 50 for operating the foot brake pedal according to a driving signal input from the control unit; When there is an object ahead, the brake is automatically operated by comprehensively judging the distance of the object in front of the vehicle and the speed of the vehicle, thereby preventing accidents in advance, and installing the brake pedal using a linear motor and an electromagnet A vehicle brake automatic control device and method that can minimize costs.

운전자가 브레이크의 동작을 자동으로 할 것인지, 아니면 수동으로 할 것인지를 선택하여 온/오프시키는 경우에 이를 전기적인 신호로 변환하여 출력하는 선택 스위치와, 전방 물체의 거리를 감지하기 위하여 광신호를 출력하고, 전방 물체에 의해 반사된 광신호를 감지하여 이를 전기적인 신호로 변환한 뒤에 출력하는 발광 소자 및 수광 소자와, 차량의 현재 속력을 감지하여 이를 전기적인 신호로 변환한 뒤에 출력하는 차속 센서와, 상기 선택 스위치가 온될 경우에, 상기 수광 소자로부터 입력되는 신호로부터 전방 물체가 기준치보다 근거리에 있는지를 판단하고, 전방 물체가 기준치보다 근거리에 있는 경우에 상기 차속 센서로부터 입력되는 신호로부터 현재 자동차의 속력이 고속 상태에 있는지를 판단하여, 이에 따라 브레이크를 자동으로 구동하기 위한 구동신호를 출력하는 제어부와, 상기 제어부로부터 입력되는 구동신호에 따라 푸트 브레이크 페달을 동작시키는 브레이크 구동부로 이루어지는 것을 특징으로 하는 자동차의 브레이크 자동 제어장치.When the driver selects whether to operate the brake automatically or manually and turns it on / off, a selection switch which converts it into an electrical signal and outputs it, and an optical signal to detect the distance of the front object And a light emitting device and a light receiving device that detect an optical signal reflected by the front object and convert the light signal into an electrical signal, and output the light signal, a light receiving device that detects the current speed of the vehicle and converts it into an electrical signal, When the selection switch is turned on, it is determined whether the front object is closer than the reference value from the signal input from the light receiving element, and when the front object is closer than the reference value, the signal of the current vehicle is input from the signal input from the vehicle speed sensor. Determines if the speed is at high speed and automatically brakes accordingly And a brake driving unit for operating a foot brake pedal according to a driving signal input from the controller. 전원이 인가되면 동작이 시작되어 모든 변수를 초기화시키는 단계와, 선택 스위치가 온이 되었는지를 판단하여 온이 된 경우에 전방 전방 물체의 감지신호를 읽어들여 전방 물체의 거리를 산출하는 단계와, 산출된 전방 물체의 거리가 기준치보다 작은지를 판단하는 단계와, 전방물체의 거리가 기준치보다 작은 경우에 차속 감지신호를 읽어들여 현재의 차속이 기준치를 초과하는지를 판단하는 단계와, 현재의 차속이 기준치를 초과하는 경우에 브레이크를 자동으로 작동시키는 단계로 이루어지는 것을 특징으로하는 자동차의 브레이크 자동 제어방법.When power is applied, the operation is started to initialize all the variables, and when the selection switch is turned on, reading the detection signal of the front front object and calculating the distance of the front object when it is turned on; Determining whether the distance of the front object is smaller than the reference value, reading the vehicle speed detection signal when the distance of the front object is smaller than the reference value, and determining whether the current vehicle speed exceeds the reference value, and the current vehicle speed is the reference value. Automatic brake control method, characterized in that the step of automatically operating the brake when exceeding. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
