Description

차량의 급제동시 추돌 경보장치Collision warning device in case of sudden braking of vehicle

본 고안은 차량의 운전시 비상 사태의 발생으로 급제동을 하는 경우, 이를 검출하여 자동으로 비상등을 점등시킴으로써 후방 차량에 의한 추돌 사고를 미연에 방지할 수 있도록 한 차량의 급제동시 추돌 경보장치에 관한 것이다.The present invention relates to a collision warning device during sudden braking of a vehicle to prevent a collision accident caused by a rear vehicle by detecting a sudden braking due to an emergency occurrence while driving a vehicle and automatically lighting an emergency light. .

일반적으로 차량에는 비상등이 구비되어 있어, 차량 운전시 비상 사태가 발생하는 경우 비상등을 점등시켜 다른 차량의 운전자에게 비상 사태의 발생을 알리고, 이에 대한 조치를 취할 수 있도록 하고 있다.In general, the vehicle is provided with an emergency light, so that when an emergency occurs while driving the vehicle, the emergency light is turned on to inform the driver of another vehicle of the occurrence of an emergency and take measures.

즉, 운전자는 차량을 운전하면서 비상 사태가 발생하였을 경우 신속하게 브레이크 페달을 밟아 차량을 급정지시킨 후 비상등 스위치를 조작하여 비상등을 점등시키도록 한다.That is, when an emergency occurs while driving a vehicle, the driver quickly presses the brake pedal to quickly stop the vehicle, and then operates the emergency light switch to turn on the emergency light.

그러나, 상기와 같이 비상 사태 경보시 운전자가 비상등 스위치를 수동으로 조작해야 하는 번거로움이 있었을 뿐만 아니라, 수동 조작으로 인해 비상 사태의 발생을 다른 운전자에게 신속하게 알리는 데 한계가 있음은 물론 이로 인하여 후방 차량에 의한 2차 추돌 사고를 초래하게 되는 문제점이 있었다.However, in addition to the inconvenience of the driver having to manually operate the emergency light switch during an emergency alert as described above, there is a limit to promptly notify another driver of the occurrence of an emergency due to the manual operation. There was a problem that causes a secondary collision by the vehicle.

본 고안은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 그 목적은 비상 사태 발생으로 인해 차량을 급제동할 경우 이를 검출하여 자동으로 비상등을 점등시킴으로써 후방 차량에 의한 추돌 사고를 예방할 수 있도록 한 차량의 급제동시 추돌 경보장치를 제공하는 데에 있다.The present invention has been devised to solve the above problems, the purpose of which is to detect a sudden braking of the vehicle due to the occurrence of emergency by automatically turning on the emergency light of the vehicle to prevent accidents caused by the rear vehicle The present invention provides a collision warning device in case of sudden braking.

이러한 목적을 달성하기 위한 본 고안의 차량의 급제동시 추돌 경보장치는, 압력센서를 통해 차량의 브레이크 압력을 측정하여 차량의 급제동 상태를 검출하고, 차량의 급제동을 검출하는 경우 ECU의 점등 제어신호에 의해 비상등 점등부를 구동하여 비상등을 자동으로 점등시키도록 함을 특징으로 한다.In order to achieve the above object, a collision warning device during braking of a vehicle according to the present invention measures a brake pressure of a vehicle through a pressure sensor to detect a sudden braking state of the vehicle, and when a sudden braking of the vehicle is detected, a collision control signal of the ECU is applied. Thereby driving the emergency light lighting unit to automatically turn on the emergency light.

이하, 첨부된 도면을 참고하여 본 고안에 의한 차량의 급제동시 추돌 경보장치의 구성 및 동작을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the collision warning device during braking of the vehicle according to the present invention.

도 1은 본 고안에 의한 차량의 급제동시 추돌 경보장치의 블록 구성도로서, 차량의 제동을 검출하는 브레이크 스위치(1)와, 상기 브레이크 스위치(1)가 온(On)되는 경우 차량 브레이크 압력을 측정하는 브레이크 압력센서(2)와, 상기 브레이크 압력센서(2)에서 측정된 압력의 상승속도가 기준치를 초과하는 지를 판단하여 기준치를 초과하는 경우 비상등 점등 제어신호를 출력하는 전자 제어 장치(Electronic Control Unit ; 이하, 'ECU' 라 칭함)(3)와, 상기 ECU(3)의 점등 제어신호에 따라 비상등(5)을 점등시키는 비상등 점등부(4)로 구성된다.FIG. 1 is a block diagram of a collision warning device for sudden braking of a vehicle according to the present invention, and includes a brake switch 1 for detecting braking of a vehicle and a vehicle brake pressure when the brake switch 1 is on. Electronic control device for determining the brake pressure sensor 2 to be measured and the rising speed of the pressure measured by the brake pressure sensor 2 exceeds a reference value and outputs an emergency light lighting control signal when the reference value is exceeded. Unit (hereinafter referred to as "ECU") 3 and an emergency light lighting unit 4 for lighting the emergency light 5 in accordance with the lighting control signal of the ECU (3).

상기와 같이 구성되는 본 고안에 의한 차량의 급제동시 추돌 경보장치의 동작을 설명하면 다음과 같다.Referring to the operation of the collision warning device when braking the vehicle according to the present invention is configured as described above are as follows.

일단, 브레이크 스위치(1)가 온되면 차량이 제동되는 상태로 제동등이 점등되게 되고, 이에 따라 ECU(3)는 추돌 경보를 위한 동작 준비 상태에 들어가게 된다.Once the brake switch 1 is turned on, the brake light is turned on in a state in which the vehicle is braked, and thus the ECU 3 enters an operation ready state for the collision warning.

그리고 나서, 브레이크 압력센서(2)를 통해 마스터 실린더(Master Cylinder)로부터 휠(Wheel)쪽으로의 유압 라인의 압력을 측정한다.Then, the pressure of the hydraulic line from the master cylinder to the wheel through the brake pressure sensor 2 is measured.

이에 따라, ECU(3)에서는 상기 브레이크 압력센서(2)에서 측정된 압력의 상승속도를 계산하고, 이 계산된 상승속도가 기준치를 초과하는 지를 판단하여 기준치를 초과하면 차량의 제동 상태를 급제동 상태로 인식하여 비상등 점등부(4)로 비상등 점등 제어신호를 출력한다.Accordingly, the ECU 3 calculates the rising speed of the pressure measured by the brake pressure sensor 2, determines whether the calculated rising speed exceeds the reference value, and when the reference value is exceeded, the braking state of the vehicle is suddenly braked. It is recognized as and outputs the emergency light lighting control signal to the emergency light lighting unit (4).

그러면, 비상등 점등부(4)는 ECU(3)의 점등 제어신호에 따라 차량의 비상등(5)을 점등시켜 후방 차량의 운전자에게 비상 사태를 신속히 알리도록 한다.Then, the emergency light lighting unit 4 turns on the emergency light 5 of the vehicle according to the lighting control signal of the ECU 3 to promptly inform the driver of the rear vehicle of the emergency situation.

이후, 운전자가 차량을 다시 출발시키기 위해 브레이크 페달에서 발을 떼면 브레이크 압력센서(2)에서 검출되는 브레이크 압력이 기준치 이하로 감소하게 되어 ECU(3)가 비상등 점등부(4)를 통해 비상등(5)의 점멸동작을 중지시키도록 한다.Subsequently, when the driver releases the brake pedal to restart the vehicle, the brake pressure detected by the brake pressure sensor 2 decreases below the reference value, and the ECU 3 causes the emergency light 5 through the emergency light lighting unit 4. To stop the flashing operation.

이상, 상기에서 설명한 바와 같이 본 고안은 브레이크 압력을 통해 차량의 급제동을 판단하여 자동으로 비상등을 점등시켜 줌으로써 비상 사태 발생시 운전자가 차량을 급제동시킨 후 일일이 비상등 스위치를 조작해야 하는 번거로움을 제거하고, 비상 사태의 발생을 신속하게 경보하여 다른 운전자에게 이를 알리어 비상 사태에 따른 추돌 사고의 발생을 예방할 수 있게 되는 효과가 있다.As described above, the present invention determines the sudden braking of the vehicle through the brake pressure to automatically turn on the emergency light to remove the hassle of having to operate the emergency light switch after the driver suddenly brakes the vehicle in case of an emergency, It is effective to quickly alert the occurrence of an emergency to other drivers to prevent the occurrence of a crash accident according to the emergency.
