Abstract

An automatic emergency lamp driving apparatus connected to a foot brake and a driving method thereof are provided to prevent an accident due to collision between vehicles by driving an emergency lamp. A pressure sensor(10) is directly connected to a foot brake pedal(1) in order to sense the pressure applied to the foot brake pedal and to output a predetermined electrical signal corresponding to the pressure. An A/D converter(20) converts the electrical signal of the pressure sensor to a digital signal and outputs the digital signal to a microcomputer(30). The microcomputer outputs a blinking control signal for an emergency lamp(2) by comparing the digital signal of the A/D converter with predetermined reference data. A driving unit(40) drives the emergency lamp according to the blinking control signal of the microcomputer.

본 발명은 차량용 자동 비상등 구동 장치에 관한 것으로, 특히 운전자가 차량의 풋브레이크 페달을 밟는 강도를 감지하여 급브레이크 시 자동으로 차량 비상등을 구동시킴으로써 후방에서 주행하는 차량 운전자가 쉽게 인지할 수 있도록 함으로써 후방 추돌 등의 사고를 미연에 방지할 수 있도록 한 풋브레이크 연동 자동 비상등 구동 장치 및 방법에 관한 것이다.The present invention relates to an automatic emergency light driving device for a vehicle, and more particularly, by detecting the intensity of the driver's foot brake pedal of the vehicle and automatically driving the vehicle emergency light during a sudden brake so that the vehicle driver driving behind can easily recognize the rear. The present invention relates to a foot brake interlock automatic emergency light driving device and method for preventing an accident such as a collision.

일반적으로 차량의 전면 및 후면 좌우 양측에는 차량이 차선변경시 후방에서 주행 중인 차량에게 알리도록 하는 방향지시등과, 정차 및 후진시에 충돌사고를 예방하도록 하는 비상등과, 브레이크등 및 후진등 등의 의사전달램프들이 설치되어 있다.In general, the front and rear left and right sides of the vehicle, the direction indicator light to notify the vehicle running in the rear when the vehicle changes lanes, the emergency light to prevent collision accidents when stopping and reversing, the brake light and the reverse light Delivery lamps are installed.

그러나, 종래에는 차량 운전자가 돌발 상황에 의해 급브레이크를 작동 시 차량 후면의 브레이크등이 점등되는 것에 의해서만 후방 운전자에게 급브레이크 상황을 알려주게 되는데, 후방 운전자는 상기 브레이크등의 점멸만으로는 전방 차량이 속도를 조금 감속하는 것인지 아니면 전방의 돌발 상황에 의해 급브레이크를 밟는 것인지의 여부를 인지하는 것이 불가능함으로써 고속 주행 시 후방의 차량이 추돌하거나 급브레이크로 인한 부상을 발생시키는 문제점이 있었다.However, in the related art, the brake driver on the rear of the vehicle is notified to the rear driver only by turning on the brake light when the vehicle driver operates the sudden brake due to a sudden situation. It is not possible to recognize whether or not to decelerate a little or to suddenly step on the sudden brake due to the sudden situation of the front, there was a problem that the rear vehicle collides or injuries due to sudden brakes during high-speed driving.

한편, 급브레이크 동작 시에는 통상 운전자가 빠른 시간 안에 비상등을 수동으로 구동시킴으로써 후방 운전자에게 급브레이크를 경고하게 되는데, 초보운전자 또는 여성운전자의 경우에는 급브레이크 동작 시 당황하여 비상등을 구동시키지 못하거나 늦게 구동시키게 됨으로써 사고의 위험성이 커지는 문제점이 있었다. On the other hand, during the sudden brake operation, the driver normally drives the emergency light quickly within a short time to warn the rear driver of the sudden brake. In the case of a novice driver or a female driver, the emergency brake may not be able to drive the emergency light or be late. By driving, there was a problem that the risk of an accident increases.

Outputs a signal to the driving means 40, and then the driving means 40 flashes the emergency light 1 lamp in accordance with a control signal input from the microcomputer 30, so that the driver of the rear vehicle is driving forward. Since it is possible to easily determine whether the vehicle is suddenly braked, it is possible to prevent a collision accident and the like in advance. (S14)
