Description

안전 거리 유지 장치Safety distance maintainer

본 발명은 자동차의 주행 시 전방 차량과의 안전 거리 유지 장치에 관한 것이다.The present invention relates to a device for maintaining a safety distance with a front vehicle when the vehicle is driven.

일반적으로, 자동차는 엔진의 구동력과 타이어와 노면의 마찰력에 의해 주행하게 되는 바, 고속 주행 시 차량의 안정성이 매우 중요하게 된다.In general, the vehicle is driven by the driving force of the engine and the friction between the tire and the road surface, the stability of the vehicle is very important at high speed.

즉, 차량 주행시에는 롤링, 요잉, 피칭 등의 동작이 연속 발생되기 때문에 이를 제어하여 보다 안정된 자세에서 주행할 수 있도록 하여야 한다.That is, since rolling, yawing, pitching, and the like are continuously generated while driving the vehicle, the vehicle must be controlled so that the vehicle can run in a more stable posture.

또한, 정지시 제동 거리를 확보하기 위하여 전방 차량과 일정 거리즉, 안전 거리를 유지해야 하는 바, 상기한 안전 거리는 전방 차량의 급정거 시 후방 차량이 안전하게 정지할 수 있는 거리를 말하게 된다.In addition, in order to secure a braking distance when stopping, it is necessary to maintain a certain distance, that is, a safety distance. The above-mentioned safety distance refers to a distance at which the rear vehicle can safely stop when the front vehicle is suddenly stopped.

즉, 차량 속도가 100Km일 경우에는 통상 100m 정도의 안전 거리를 확보해야 안전한 제동이 가능하게 되는 것이다.In other words, when the vehicle speed is 100Km, a safe braking is possible only by securing a safety distance of about 100m.

그러나, 상기한 바와 같은 안전 거리를 확보하지 않고 주행하게 됨으로써 급제동 시 추돌 사고가 많이 발생되는 문제점이 있다.However, there is a problem that a lot of collision accidents occur during sudden braking by driving without securing the safety distance as described above.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 운전자가 안전 거리를 유지하지 않고 주행 시 전방 차량과 안전 거리를 주지시켜 추돌 사고를 방지할 수 있는 안전 거리 유지 장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a safety distance maintaining apparatus capable of preventing a collision accident by notifying a safety distance with a vehicle ahead of a driver when the driver does not maintain a safety distance while driving.

상기한 목적을 실현하기 위하여 본 발명은 ECU에 연결된 차속 센서와, 상기한 ECU에 연결된 전방 차량 속도 감지 수단과, 상기한 차속 센서와 전방 차량의 차속 감지 후 안전 거리를 확보하지 못했을 때 경보를 발하는 부저와, 상기한 안전 거리 미 확보 시 계기판에 표시되는 표시 수단으로 구성함을 특징으로 한다.In order to achieve the above object, the present invention provides an alarm when a vehicle speed sensor connected to an ECU, a front vehicle speed detecting means connected to the ECU, and a safety distance are not secured after detecting the vehicle speed of the vehicle speed sensor and the front vehicle. Buzzer, and the display means displayed on the instrument panel when the safety distance is not secured.

도면은 본 발명에 따른 안전 거리 유지 장치를 도시한 블록도로서, ECU(1)에 연결된 차속 센서(2)와, 상기한 ECU(1)에 연결된 전방 차량 속도 감지 수단과, 상기한 차속 센서(2)와 전방 차량의 차속 감지 후 안전 거리를 확보하지 못했을 때 경보를 발하는 부저(3)와, 상기한 안전 거리 미 확보 시 계기판에 표시되는 표시 수단(4)으로 구성되어 있다.The figure is a block diagram showing a safety distance maintaining apparatus according to the present invention, wherein the vehicle speed sensor 2 connected to the ECU 1, the front vehicle speed detecting means connected to the ECU 1, and the vehicle speed sensor ( 2) and a buzzer (3) for generating an alarm when a safety distance is not secured after detecting a vehicle speed of the front vehicle, and a display means (4) displayed on the instrument panel when the safety distance is not secured.

상기한 전방 차량 속도 감지 수단은 ECU(1)에 연결된 연산기(5)와, 상기한 연산기(5)에 연결됨과 아울러 차량 전방에 설치되어 전방 차량을 촬영하는 카메라(6)로 구성되어 있다.The front vehicle speed detecting means comprises a calculator 5 connected to the ECU 1 and a camera 6 connected to the calculator 5 and installed in front of the vehicle to photograph the front vehicle.

즉, 상기한 카메라(6)가 전방 차량을 촬영하면 이를 연산기(5)에서 전달받아 소정의 플로우로 전방 차량의 차속을 체크하게 되는 것이다.That is, when the camera 6 photographs the front vehicle, it is received by the calculator 5 to check the vehicle speed of the front vehicle with a predetermined flow.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 차량이 주행하게 되면 ECU(1)가 차속 센서(2)를 통해 현재 차량의 속도를 체크하게 된다.Referring to the operation and effect of the present invention as described above, when the vehicle travels, the ECU 1 checks the speed of the current vehicle through the vehicle speed sensor 2.

현재 차속을 체크한 후 카메라(6)를 동작시켜 전방 차량을 촬영함과 아울러 상기한 정보를 연산기(5)에서 연산하여 전방 차량의 속도 및 전방 차량과 자기 차량과의 거리를 체크하게 된다.After checking the current vehicle speed, the camera 6 is operated to photograph the front vehicle, and the above information is calculated by the calculator 5 to check the speed of the front vehicle and the distance between the front vehicle and the own vehicle.

전방 차량의 속도가 ECU(1)에 전달되면 상기한 자기 차량의 차속과 이를 비교하게 되는 바, 상기한 비교 후 전방 차량과의 안전 거리가 가까운 상태이면 ECU(1)가 부저(3)를 동작시킴과 아울러 표시 수단(4)에 경고 표시를 하게 된다.When the speed of the front vehicle is transmitted to the ECU 1, the vehicle 1 is compared with the vehicle speed of the own vehicle. When the safety distance with the front vehicle is close after the comparison, the ECU 1 operates the buzzer 3. In addition, the warning means is displayed on the display means 4.

경고 표시가 나타남과 아울러 부저(3)가 울리게 되면 운전자가 안전 거리를 유지하게 되는 것이다.When the warning sign is displayed and the buzzer 3 rings, the driver maintains the safety distance.

물론, 상기한 안전 거리는 자기 차량과 전방 차량의 차속을 연산하여 최적의 거리를 산출하게 된다.Of course, the safety distance is calculated by calculating the vehicle speed of the vehicle and the front vehicle to calculate the optimum distance.

이상과 같이 본 발명은 차속 센서와 카메라에 연결된 ECU로 전방 차량과 자기 차량 사이의 거리를 체크함으로써 추돌 사고를 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention has an advantage of preventing a collision accident by checking a distance between a vehicle ahead and a vehicle with an ECU connected to a vehicle speed sensor and a camera.
