본 고안의 실시예를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 고안의 실시예는 도 2에서와 같이, 운전자에 의해 조작되어 비상등 작동 신호를 출력하는 비상등 스위치(SWHZ)와; 점멸기(FL)에 접속된 비상등(LPHZ)과; 인가되는 제어신호에 따라 배터리 전원을 상기 점멸기(FL)를 통해 비상등(LPHZ)에 공급하는 비상등 릴레이(RY)와; 브레이크 페달의 작동을 검출하는 브레이크 작동 스위치(SWBR)와; 차량의 속도를 검출하는 차속 센서(10)와; 차량의 가속도를 검출하는 가속도 센서(20)와; 상기 비상등 스위치(SWHZ)에 따라 상기 비상등 릴레이(RY)를 여자시켜서 비상등(LPHZ)을 작동시키고, 브레이크 작동 스위치(SWBR)에서 브레이크 작동 신호가 인가되면 제동등(LPBR)을 점등시키는 동시에 차속 센서(10)와 가속도 센서(20)에서 인가되는 차속과 가속도에 따라 급제동을 판단하여 급제동시 상기 비상등 릴레이(RY)를 여자시켜서 비상등(LPHZ)을 일정시간(t) 동안 작동시키는 비상등 제어부(30)를 포함하여 구성된다.Embodiment of the present invention, as shown in Figure 2, the emergency light switch (SW HZ ) which is operated by the driver to output the emergency light operation signal; An emergency light LP HZ connected to the flasher FL; An emergency light relay RY for supplying battery power to the emergency light LP HZ through the flasher FL according to an applied control signal; A brake actuation switch SW BR for detecting actuation of the brake pedal; A vehicle speed sensor 10 for detecting a speed of the vehicle; An acceleration sensor 20 for detecting an acceleration of the vehicle; The emergency light relay RY is activated according to the emergency light switch SW HZ to activate the emergency light LP HZ , and when the brake operation signal is applied from the brake operation switch SW BR , the brake light LP BR is turned on. Emergency braking control to determine the sudden braking according to the vehicle speed and acceleration applied from the vehicle speed sensor 10 and the acceleration sensor 20 to activate the emergency light (LP HZ ) for a predetermined time (t) by exciting the emergency light relay (RY) during sudden braking It comprises 30.
첫째로, 상기 비상등 제어부(30)는 운전자가 조작하는 비상등 스위치(SWHZ)에 따라 비상등(LPHZ)을 작동/작동중지 시킨다.First, the emergency light control unit 30 operates / stops the emergency light LP HZ according to the emergency light switch SW HZ operated by the driver.
즉, 비상시 운전자가 비상등 스위치(SWHZ)를 온 (ON)으로 조작하여 비상등 작동 신호를 인가하면, 비상등 제어부(30)는 비상등 릴레이(RY)를 여자시켜서 배터리 전원을 점멸기(FL)를 통해 비상등(LPHZ)에 공급하여 비상등(LPHZ)을 점멸시킨다. 그리고 비상 상태가 해제되어 운전자가 비상등 스위치(SWHZ)를 오프 (OFF)로 조작하여 비상등 작동 중시 신호가 인가되면 비상등 제어부(30)는 비상등 릴레이(RY)를 여자시켜서 점멸기(FL)에 공급되던 배터리 전원을 차단하여 비상등(LPHZ)을 소등시킨다.That is, when the driver operates the emergency light switch SW HZ ON to apply the emergency light operation signal, the emergency light control unit 30 activates the emergency light relay RY to turn on the battery power through the flasher FL. min. for (LP HZ) thereby flashing the hazard lights (LP HZ). When the emergency state is released and the driver operates the emergency light switch SW HZ to OFF and the emergency light operation importance signal is applied, the emergency light control unit 30 energizes the emergency light relay RY to supply the flasher FL. Turn off the battery and turn off the emergency light (LP HZ ).
둘째로, 상기 비상등 제어부(30)는 운전자가 브레이크 페달을 작동하여 브레이크 작동 스위치(SWBR)에서 브레이크 작동 신호가 인가되면 제동등(LPBR)을 점등시키는 동시에 차속 센서(10)와 가속도 센서(20)에서 인가되는 차속과 가속도에 따라 급제동을 판단하여 비상등(LPHZ)을 자동으로 일정시간(t) 동안 작동시킨다.Secondly, when the driver operates the brake pedal and the brake operation signal is applied from the brake operation switch SW BR , the emergency light control unit 30 turns on the brake light LP BR and at the same time the vehicle speed sensor 10 and the acceleration sensor 20. The emergency braking (LP HZ ) is automatically operated for a certain time (t) by judging sudden braking according to the vehicle speed and acceleration applied from
즉, 브레이크 작동 신호가 인가되면 이때의 차속을 검출한다. 차속에 따라 브레이크 페달을 밟음으로 감속되는 효과가 다르기 때문에 상기 비상등 제어부(30)는 차속에 따라 급제동을 판단하기 위한 설정 가속도(실제로는 감속됨으로 음의값을 갖는 가속도가 설정됨)를 저장하고 있으며, 브레이크 작동 신호가 인가되는 경우 차속을 검출하여 설정 가속도를 선택한다. 그리고 가속도 센서(20)에서 인가되는 가속도가 상기 선택된 설정 가속도 이하인지를 판단하여 설정 가속도 이하인 경우 일정시간(t) 동안 비상등 릴레이(RY)를 여자시켜서 배터리 전원을 점멸기(FL)를 통해 비상등(LPHZ)에 공급하여 비상등(LPHZ)을 자동으로 점멸시킨다.That is, when the brake operation signal is applied, the vehicle speed at this time is detected. Since the effect of decelerating by depressing the brake pedal according to the vehicle speed is different, the emergency light control unit 30 stores a set acceleration (actually, an acceleration having a negative value is set as it is decelerated) to determine the sudden braking according to the vehicle speed. When the brake operation signal is applied, the vehicle speed is detected and the set acceleration is selected. When the acceleration applied from the acceleration sensor 20 is equal to or less than the selected set acceleration, the emergency light relay RY is excited for a predetermined time t when the acceleration is less than or equal to the set acceleration, and the battery power is turned on through the flasher FL. HZ ) to flash the emergency light (LP HZ ) automatically.
상기 비상등 제어부(30)는 차속과 감속도에 의해 급제동으로 판단되면 브레이크 작동 스위치(SWBR)로부터 브레이크 작동 신호가 인가되는 동안 비상등(LPHZ)을 점멸시킬 수도 있다.The emergency light control unit 30 may blink the emergency light LP HZ while the brake operation signal is applied from the brake operation switch SW BR when it is determined that the vehicle is suddenly braked by the vehicle speed and deceleration.
이와 같이, 급제동시 자동으로 비상등이 작동되면, 뒤따라오는 후방 차량에게 급제동을 보다 신속하게 알릴 수 있어 후방 차량과의 사고 발생을 줄일 수 있고, 운전자는 브레이크 페달만 작동시키면 되므로 급제동과 함께 비상등을 작동시켜야 하는 부담이 줄어들게 된다.As such, when the emergency light is automatically activated during sudden braking, it is possible to notify the following rear vehicle of rapid braking more quickly, thereby reducing the occurrence of an accident with the rear vehicle, and the driver only needs to operate the brake pedal to operate the emergency light together with sudden braking. The burden of doing so will be reduced.
본 고안 비상등 자동 작동 장치는 운전자에 의해 브레이크 페달이 작동되면, 차속과 가속도에 의해 급제동을 검출하여 급제동시 비상등을 자동으로 작동시키는 것으로, 후방 차량에게 보다 신속하게 급제동을 알릴 수 있으며 비상등 작동에 대한 운전자의 부담이 줄어들므로 운전자로 하여금 안전 운행을 할 수 있도록 기여하는 유용한 것이다.When the brake pedal is operated by the driver, the emergency light automatic device of the present invention detects sudden braking by vehicle speed and acceleration and automatically operates the emergency light during sudden braking, which can notify the rear vehicle of rapid braking more quickly. As the burden on the driver is reduced, it is useful to contribute to the driver to drive safely.
