본 발명은 운행 중 충돌시 탑승자의 최소화하기 위한 시스템에 관한 것으로서, 더욱 상세하게는 전동안전벨트의 고장을 진단함과 더불어 우천시 경보기능의 신뢰성을 더욱 향상시킨 차량 충돌 안전 시스템에 관한 것이다. The present invention relates to a system for minimizing occupants during a collision during driving, and more particularly, to a vehicle collision safety system that diagnoses a failure of an electric safety belt and further improves reliability of a warning function in rainy weather.

근래 들어, 차량 운행 중에 발생하는 각종 사고로부터 탑승자의 피해를 최소화하는 안전벨트나 에어백과 같은 사후안전수단에서 벗어나 운전 중에 잠재한 사고를 예측하여 탑승자에게 경보함으로써 사고를 미연에 방지하기 위한 시도가 활발하게 진행되고 있다. In recent years, attempts have been made to prevent accidents by warning the occupants by estimating potential accidents while driving away from safety belts or airbags that minimize the damage of occupants from various accidents occurring while driving the vehicle. Is going on.

이러한 시도 중의 하나로 자차의 전방에 대한 대살된 레이져빔이 선행차량의 후미등 주위에 부착된 반사판에 의하여 반사된 후에 되돌아오기까지의 시간을 측정하여 자차와 선행차량과의 차간거리를 산출하고, 상기 산출된 차간거리, 정지거리 및 자차와 선행차량의 상대속도를 종합적으로 고려하여 충돌가능성이 있다가 판단될 때 경보를 발하는 시스템에 개발되었다. In one of these attempts, the distance between the own vehicle and the preceding vehicle is calculated by measuring the time from when the slaughtered laser beam to the front of the vehicle is reflected by the reflector attached around the tail light of the preceding vehicle and then returned. It has been developed for a system that generates an alarm when it is determined that there is a possibility of collision, taking into account the inter-vehicle distance, the stopping distance, and the relative speeds of the own vehicle and the preceding vehicle.

도 1 은 종래의 차량 충돌 안전 시스템으로서, 도시된 바와 같이, 크게 제어장치(10), 주제어부(12), 구동부(14), 경보장치(20), 제동장치(30), 차간거리 감지부(40), 차속센서(50), 모터구동부(60,80), 및 전동안전벨트(70,80)로 이루어진다. 1 is a conventional vehicle collision safety system, as shown, large control device 10, main control unit 12, drive unit 14, alarm device 20, braking device 30, inter-vehicle distance detection unit 40, the vehicle speed sensor 50, the motor driving units 60 and 80, and the electric safety belts 70 and 80.

먼저 차간거리 감지부(40)는 레이져 빔을 발사하여 레이져 빔이 선행차량의 반사판에 반사되는 되돌아오는 데 걸리는 시간을 통해 차간거리를 측정하고, 차속센서(50)는 현재 주행 중인 차량의 속도를 측정하여 이를 주제어부(10)로 전송한다.First, the inter-vehicle distance sensing unit 40 measures the inter-vehicle distance through the time it takes for the laser beam to be reflected back to the reflector of the preceding vehicle by firing the laser beam, and the vehicle speed sensor 50 measures the speed of the vehicle currently being driven. The measurement is transmitted to the main control unit 10.

경보장치(20)는 차량의 충돌 가능성이 높을 경우 차량의 충돌위험을 탑승자 에게 경보하는 장치이며, 제동장치(30)는 충돌가능성에 따라서 따라서 선행차량과의 거리를 유지하기 위해 차량을 감속시키며, 모터구동부(60,80)는 충돌위험시 전동안전벨트(70,90)를 구동시켜 충돌로 인한 에어백이 전개될 때 압력에 의한 상해를 최소화한다.The alarm device 20 is a device that alerts the occupant of the risk of collision of the vehicle when the collision probability of the vehicle is high, and the braking device 30 decelerates the vehicle to maintain the distance to the preceding vehicle according to the possibility of collision. The motor driving units 60 and 80 drive the electric safety belts 70 and 90 in case of a collision risk to minimize injury due to pressure when the airbag due to the collision is deployed.

주제어장치(10)는 주제어부(12)와 구동부(12)로 이루어지는데, 구동부(14)는 주제어부(12)의 제어하에 경보장치(20)를 구동시킨다.The main controller 10 includes a main controller 12 and a driver 12, which drives the alarm device 20 under the control of the main controller 12.

마지막으로, 주제어부(12)는 차량 충돌 안전 시스템을 전체적으로 제어하는 것으로서, 차량의 주행시 차간거리 감지부(40)와 차속센서(50)로부터 각각 전송되는 자차와 선행차량과의 차간거리와 현재 자차의 주행속도를 수신하여 충돌위험성을 판단하고 충돌위험성이 있는 경우, 구동부(14)를 이용하여 경보장치(20)를 구동시켜 탑승자가 현재 충돌위험이 있음을 인식하도록 함과 더불어 제동장치(30)를 통해 차량의 속도를 감속시킨다.Lastly, the main controller 12 controls the vehicle collision safety system as a whole, and the distance between the host vehicle and the preceding vehicle transmitted from the inter-vehicle distance sensing unit 40 and the vehicle speed sensor 50 during the driving of the vehicle, and the current host vehicle. If the collision risk is determined by receiving the traveling speed, and there is a collision risk, the alarm unit 20 is driven by using the driving unit 14 to recognize that the occupant is currently in danger of collision and the braking device 30. Slows the vehicle down.

이와 더불어, 충돌시엔 모터 구동부(60,80)를 구동시켜 전동안전벨트(70,90)가 동작할 수 있도록 함으로써, 차량 충돌시 탑승자가 에어백에 의한 상해를 최소화시킨다.In addition, by driving the motor drive unit (60, 80) in the event of a collision, the electric safety belts (70, 90) to operate, thereby minimizing the injuries of the occupant due to the air bag during the vehicle crash.

이러한 종래의 차량 충돌 안전 시스템은 전술한 바와 같이, 차량의 충돌 위험성을 판단하고 이를 통해 탑승자의 안전 운행을 지원하지만 다음과 같은 문제점이 있었다. As described above, the conventional vehicle collision safety system determines the risk of collision of the vehicle and thereby supports the safe driving of the occupant, but has the following problems.

두번째로, 우천시와 같이 날씨가 양호하지 않거나 빗길 주행시 차간거리 감지부(40)의 레이져 빔에 의한 차간거리 측정이 용이하지 않다는 것이다. 이에 따라, 차간거리 측정의 정확성이 떨어지게 되었고, 이에 따라 충돌 위험성 판단이 정확하게 되지 않는 다는 문제점이 있었다. Secondly, it is not easy to measure the distance between the laser beams of the inter-vehicle distance detecting unit 40 when the weather is not good or when driving in rainy weather. Accordingly, the accuracy of the inter-vehicle distance measurement is lowered, and thus there is a problem that the collision risk determination is not accurate.

즉, 충돌시 에어백에 의한 상해 예방이 미흡하였고, 날씨가 양호하지 않는 경우에 있서 차간거리 측정의 부정확성으로 인한 충돌 위험성 판단이 부정확하게 되어 차량 충돌시와 충돌 위험성 판단에 있어서 신뢰성이 저하된다는 문제점이 있었다.In other words, in case of collision, the prevention of injury by airbag is insufficient, and in the case of bad weather, collision risk judgment due to inaccuracy of distance measurement is inaccurate and reliability in vehicle collision and collision risk judgment is deteriorated. there was.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 전동안전벨트의 고장을 진단함과 더불어 우천시 등의 경우 충돌위험성 판단의 신뢰성을 더욱 향상시킨 차량 충돌 안전 시스템을 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a vehicle collision safety system for diagnosing a failure of an electric safety belt and further improving the reliability of collision risk determination in case of rain.

이하에서는 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

참고로, 본 발명에 따른 실시예에서는 종래의 기술과 동일한 구성요소에 있어서는 그 상세한 설명을 생략한다.For reference, in the embodiment according to the present invention, the detailed description of the same components as in the prior art will be omitted.

본 발명에 따른 차량 충돌 안전 시스템은 우적센서(16a)와 와이퍼 동작상태 감지부(16b), 우적상태 판단부(16), 비교부(16), 및 전류센서(62,64)를 더 구비한다.The vehicle collision safety system according to the present invention further includes a raindrop sensor 16a, a wiper operation state detector 16b, a raindrop determiner 16, a comparer 16, and a current sensor 62, 64. .

먼저, 우적센서(16a)는 비나 눈 등에 의한 현재 노면 상태 신호를 전송하고, 와이퍼 동작상태 감지부(16b)는 비나 눈에 의해 탑승자가 작동시킨 와이퍼 동작 신호를 전송한다.First, the rain sensor 16a transmits a current road surface condition signal by rain or snow, and the wiper operation state detection unit 16b transmits a wiper operation signal operated by the occupant by rain or snow.

이러한 우적센서(16a)나 와이퍼 동작상태 감지부(16b)는 우천시와 같은 날씨에 의해 레이져 빔을 이용한 차량거리 측정이 용이하지 않을 경우에 보다 정확한 충돌 위험성 판단이 이루어지도록 한다.The rain sensor 16a or the wiper operation state detection unit 16b allows a more accurate collision risk determination to be made when the vehicle distance measurement using the laser beam is not easy due to the weather, such as during rainy weather.

전류센서(62)는 모터 구동부(60)의 인가된 전류를 감지하여 이를 비교부(18)로 전송하고, 비교부(18)는 상기한 전류센서(62)로부터 전송된 전류값과 주제어부(12)로부터 모터 구동부(60,80)로 인가되는 전류값을 비교한다.The current sensor 62 detects the applied current of the motor driver 60 and transmits it to the comparator 18, and the comparator 18 is the current value and the main control unit (C) transmitted from the current sensor 62. The current values applied to the motor driving units 60 and 80 from 12) are compared.

주제어부(12)는 본 발명에 따른 차량 충돌 안전 시스템을 전체적으로 제어하는 것으로서, 우적센서(16a)로부터 현재 노면상태 정보 및/또는 와이퍼 동작상태 감지부(16b)로부터 와이퍼 동작 신호가 전송되면 이를 통해 해당 신호에 따른 차량 경보 시점을 제어하는 데, 예를 들어, 노면에 비가 고여 있는 등 노면상태가 좋지 못하거나 폭우로 인한 와이퍼 동작 속도가 빠른 경우 이를 보정하여 날씨가 좋은 정상상태의 차간거리에 비해 차간거리가 멀 때 경보시점과 감속시점을 결정한다.The main controller 12 controls the vehicle collision safety system according to the present invention as a whole. When the current road surface information and / or the wiper operation signal are transmitted from the wiper operation state detection unit 16b from the raindrop sensor 16a, Control the vehicle alarm point according to the signal, for example, if the road condition is bad, such as raining on the road surface or the wiper operation speed due to heavy rain is corrected to compensate for the weather distance in the normal state with good weather conditions. When the distance is far, determine the alarm point and deceleration point.

이는 우천시와 같이 날씨가 좋지 않은 경우엔 일반적인 경우와 달리 제동력의 차이가 발생하게 되고, 탑승자의 주위가 분산되기 쉽기 때문이다.This is because, in the case of bad weather, such as rainy weather, a difference in braking force occurs unlike in the general case, and the surroundings of passengers are easily dispersed.

또한, 주제어부(12)는 전류값을 통해 전동안전벨트(70,90)의 이상 유무를 판단하는데, 이는 전동안전벨트(70,90)로 인가되는 전류값을 전류센서(62,64)가 감지하고, 이 전류값과 주제어부(12)가 모터구동부(60,80)에 지시한 전류값을 비교부 (18)가 비교하여 이를 주제어부(18)로 전송함으로써 이루어진다.In addition, the main control unit 12 determines whether there is an abnormality of the electric safety belts 70, 90 through the current value, which is the current sensor 62, 64 is applied to the current value applied to the electric safety belts 70, 90 And the current value and the current value instructed by the main controller 12 to the motor drive units 60 and 80 are compared by the comparator 18 and transmitted to the main controller 18.

주제어부(12)는 상기한 비교부(18)에 의한 전류값 비교 결과 전류값에 이상이 있을 경우 구동부(14)를 제어하여 그 결과값이 임계치를 초과하는 경우엔 표시부(22) 등을 통해 시각적으로 또는 청각적으로 현재 전동안전벨트(70)가 이상있음을 출력한다.The main control unit 12 controls the driving unit 14 when the current value comparison result by the comparing unit 18 is abnormal, and when the result value exceeds the threshold value, the display unit 22 or the like. Visually or audibly, the electric safety belt 70 outputs a fault.

따라서, 탑승자는 현재 전동안전벨트(70,90)의 이상 유무를 확인할 수 있게 된다.Therefore, the occupant can check whether there is an abnormality of the electric safety belts 70 and 90 at present.

본 발명은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수 있다. The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the scope of the technical idea of the present invention.

이와 같이 구성되는 본 발명에 따르면, 전동안전벨트로 인가되는 전류값과 주제어부로부터 인가되는 전류값 비교를 통한 전동안전벨트의 고장을 진단하고, 이와 더불어 우천시와 같이 날씨가 좋지 않을 경우 경보기능과 제동기능을 보정하여 탑승자가 시스템의 신뢰성을 향상시킬 수 있다. According to the present invention configured as described above, by diagnosing the failure of the electric safety belt by comparing the current value applied to the electric safety belt and the current value applied from the main control unit, and in addition to the alarm function when the weather is bad, such as rainy weather By adjusting the braking function, the occupant can improve the reliability of the system.
