Description
본 고안은 자동차의 추돌방지 경보장치에 관한 것으로, 특히 후미에 오는 차량이 안전거리를 확보하지 않고 주행하고 있을 때 후미 차량의 운전자에게 경보를 하므로써 안전거리를 확보하도록 유도하는 자동차의 추돌방지 경보장치에 관한 것이다.The present invention relates to an anti-collision warning device of a vehicle, and more particularly, to an anti-collision warning device of a car that induces a safety distance by alerting a driver of a rear vehicle when a vehicle coming to the rear is driving without securing a safety distance. It is about.
근래 들어, 센서기술 및 이를 응용한 제어기술의 발달에 따라 운전의 편의를 도모함은 물론이고 안전까지도 도모할 수 있도록 한 시스템이 개발되어 자동차에 활발하게 탑재되고 있다.Recently, according to the development of the sensor technology and the control technology using the same, a system has been developed and mounted on the vehicle to facilitate driving as well as safety.
이 중에서 운전자의 운전상의 편의를 도모하기 위한 시스템으로는 크루즈 시스템이나 자동항법 시스템을 들 수가 있고, 운전자의 안전을 도모하기 위한 시스템으로는 전자식 시트벨트, 에어백 시스템, 전방충돌 방지시스템, 측방충돌 방지시스템 등을 들 수가 있으며, 이외에도 열거할 수 없을 정도로 다양한 안전 시스템이 제안되어 있는 실정이다.Among them, cruise system or auto navigation system can be used for the driver's convenience, and electronic seat belt, air bag system, forward collision prevention system, and side collision prevention system can be used for the driver's safety. Systems and the like, and various safety systems have been proposed that cannot be listed.
한편, 근래에 들어서는 이러한 안전시스템의 발달로 인한 부작용으로 운전자가 전방주시나 주의운전을 태만히 하여 선행차량과의 안전거리가 확보되지 못하는 경우가 종종 발생하며, 이에 따라 자칫 추돌사고가 발생될 위험성이 있었다.On the other hand, in recent years, as a side effect of the development of this safety system, the driver often neglects forward driving or careful driving, so that the safety distance from the preceding vehicle is often not secured. Therefore, there is a risk of a collision accident. there was.
특히, 화물트럭의 운전자인 경우에는 물류비용을 절감하기 위하여 장시간동안 무리하여 운전하는 경우가 신문지상이나 전파매체를 통하여 소개되고 있는 바, 이러한 졸음 운전의 경우에는 자기의 생명만이 아니라 자칫 타인의 생명까지도 위태롭게 하고 있다.Particularly, in the case of a driver of a cargo truck, a case of excessive driving for a long time is introduced through newspapers or radio media to reduce logistics costs. Even life is at stake.
그러나, 현재까지는 이러한 안전 거리 미확보를 감지하여 후미 차량에게 경보하는 시스템이 제안되어 있지 않는 실정에 있다.However, up to now, there is no proposal for a system that detects such a safety distance not secured and alerts the rear vehicle.
본 고안은 전술한 문제점을 해결하기 위하여 안출된 것으로서, 후미에 오는 차량이 안전거리를 확보하지 않고 주행하고 있을 때 후미 차량의 운전자에게 적절한 수단을 사용하여 경보하므로써 안전거리의 미확보로 인한 추돌사고를 미연에 방지할 수 있도록 한 자동차의 추돌방지 경보장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve the above-mentioned problems, and it is possible to prevent collisions due to the inability to secure the safety distance by warning the driver of the rear vehicle by using an appropriate means when the vehicle coming to the rear is running without securing the safety distance. It is an object of the present invention to provide an anti-collision warning device for a vehicle that can be prevented.

이하에는 본 고안의 양호한 실시예를 첨부한 도면을 참조하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
도 1은 본 고안에 따른 자동차의 추돌방지 경보장치의 블록구성도이다. 도 1에 도시한 바와 같이, 본 고안에 따른 자동차의 추돌방지 경보장치에서는 마이크로 프로세서(5)를 통합적인 제어수단으로 사용하며, 이외의 주요구성으로는 후미에 오는 차량을 감지하기 위한 전파를 송수신하기 위한 안테나(7) 및 레이더(1), 레이더(1)를 구동하기 위한 레이더 구동부(2), 상기 레이더(1)에 의해 수신된 신호를 마이크로 프로세서(5)가 처리하기에 적합한 형태로 변환하는 신호처리부(3), 자차의 절대속도를 감지하는 차속검출부(4) 및 경보수단으로서의 브레이크등을 구동하는 브레이크등 구동부(6)가 있다.1 is a block diagram of an anti-collision warning device for a vehicle according to the present invention. As shown in Figure 1, the collision prevention alarm device of the vehicle according to the present invention uses the microprocessor (5) as an integrated control means, other than the main configuration to transmit and receive radio waves for detecting the vehicle coming to the rear For converting the signal received by the radar 1, the radar driver 2 for driving the radar 1, the signal received by the radar 1 into a form suitable for processing by the microprocessor 5 There is a signal processing section 3, a vehicle speed detection section 4 for detecting the absolute speed of the host vehicle, and a brake light drive section 6 for driving a brake light as an alarm means.
이하에는 전술한 구성을 가지는 본 고안의 자동차의 추돌방지 경보장치의 동작에 대해서 상세하게 설명한다.Hereinafter, the operation of the collision prevention alarm device of the vehicle of the present invention having the above-described configuration will be described in detail.
먼저, 자차가 운행중인 상태에서 마이크로 프로세서(5)는 레이더 구동부(2)를 제어하여 레이더(1)를 구동하므로써 안테나(7)에서 소정의 고주파 신호가 자차의 후방을 향하여 송출되도록 한다.First, while the host vehicle is running, the microprocessor 5 controls the radar driver 2 to drive the radar 1 so that a predetermined high frequency signal is transmitted from the antenna 7 toward the rear of the host vehicle.
이렇게 하여 고주파 신호가 송출된 후에 레이더(1) 및 안테나(7)는 수신모드로 변환되어 동일차선의 후미 차량에 부딪혀서 되돌아오는 신호를 수신하게 된다. 다음, 이렇게 수신된 검출신호는 신호처리부(3)를 통하여 마이크로 프로세서(5)가 처리하기에 적당한 형태 및 크기로 변환되고, 이후에 마이크로 프로세서(5)에 제공되어 후미 차량과의 거리를 연산하는데 사용된다.In this way, after the high frequency signal is transmitted, the radar 1 and the antenna 7 are converted to the reception mode and receive a signal coming back by hitting the rear vehicle in the same lane. Next, the received detection signal is converted into a shape and size suitable for processing by the microprocessor 5 through the signal processor 3, and then provided to the microprocessor 5 to calculate a distance from the rear vehicle. Used.
즉, 마이크로 프로세서(5)는 고주파 신호의 송출시점부터 상기 검출신호가 수신되기 까지의 시간을 카운트하여 자차와 후미 차량과의 거리를 일정간격으로 산출하게 된다.That is, the microprocessor 5 calculates the distance between the host vehicle and the rear vehicle at a predetermined interval by counting the time from when the high frequency signal is transmitted until the detection signal is received.
마이크로 프로세서(5)는 또한 차속검출부(4)에서 제공된 신호에 의거하여 자차의 절대속도를 연산하는데, 상기 연산된 자차의 절대속도와 상기 산출된 후미 차량과의 거리를 종합적으로 판단한 후에 추돌의 위험성이 있는 경우에는 브레이크등 구동부(6)를 제어하여 브레이크등을 구동하므로써 후미 차량의 운전자에게 추돌의 위험성이 있음을 경보하게 된다.The microprocessor 5 also calculates the absolute speed of the host vehicle based on the signal provided by the vehicle speed detection unit 4, after comprehensively determining the absolute speed of the calculated host vehicle and the calculated rear vehicle and the risk of collision. In this case, the brake lamp driving unit 6 is controlled to drive the brake lamp to alert the driver of the rear vehicle that there is a risk of collision.
이 경우에 브레이크등의 점등패턴은 통상적인 브레이크 페달의 조작에 따른 점등패턴과는 달리 소정의 주기로 점등과 소등을 반복하도록 하는 것이 양호하다.In this case, it is preferable that the lighting pattern of the brake lamp is repeatedly turned on and off at a predetermined cycle, unlike the lighting pattern according to the operation of the normal brake pedal.
본 고안은 전술한 실시예에 국한되지 않고, 본 고안의 기술사상이 허용하는 범위내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above-described embodiment, and various modifications can be made within the range permitted by the technical idea of the present invention.
이상에서 설명한 바와 같은 본 고안의 자동차의 추돌방지 경보장치에 따르면, 후미 차량의 운전자가 안전거리를 확보하지 않고 뒤따라오는 경우에 이를 감지하여 경보하므로써 안전사고 미확보로 인한 추돌의 위험성을 미연에 방지하는 효과가 있다.According to the collision avoidance alarm device of the vehicle of the present invention as described above, by detecting and alerting the driver when the driver of the rear vehicle does not secure a safety distance, it prevents the risk of a collision due to the non-secured accident It works.
