Abstract

PURPOSE: A rear collision warning device is provided to reduce wire of a vehicle by sensing a rear obstacle with a sensor, and to improve precision by moving the sensor light and left in a rear bumper. CONSTITUTION: A rear crush warning device comprises a sensor moving unit(10) mounted in a rear bumper of a vehicle to move as roof, lack or pinion type by a step motor(15); a distance sensor(13) installed on a rail(17); an ultrasonic transceiver buffer(7) communicating distance with the obstacle without wire; a control unit(5) calculating distance value input from the ultrasonic transceiver buffer while controlling the step motor; and a display unit(3) indicating position of the sensor, a buzzer, and the obstacle. The sensor detects the distance value with the obstacle and inputs the distance value into the ultrasonic transceiver buffer. Then, the control unit controls the step motor and displays the input distance value on the display unit. The sensor displays the position of the obstacle by detected distance value, and repeatedly detects the obstacle by moving toward the other end. Thereby, the rear crush warning device reduces wires by sensing the rear obstacle with one sensor and precisely detects the position of the obstacle by moving the sensor right and left.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 설명하기로 한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 1을 참조하면, 본 발명에 따른 후방 충돌 경보 장치가 도시되어 있다.1, there is shown a rear collision warning device according to the present invention.

본 발명에 따른 센서 이동체부(10)는 차량의 후방 범퍼(11)내에 설치된다. 거리 센서(13)는 레일(17)상에 장착되며, 스텝모터(15)에 의해서 루프식 또는 랙과 피니언식 등으로 이동가능하다.The sensor moving part 10 according to the present invention is installed in the rear bumper 11 of the vehicle. The distance sensor 13 is mounted on the rail 17 and is movable by a step motor 15 in a loop or rack and pinion manner.

상기 센서(13)에서 검지된 장애물과의 거리값은 초음파 송수신 버퍼(7)로 무선으로 입력된다.The distance value with the obstacle detected by the sensor 13 is wirelessly input to the ultrasonic transmission / reception buffer 7.

제어부(5)는 상기 스텝모터(15)를 제어하며, 또한 상기 초음파 송수신 버퍼(7)로부터 입력된 거리값을 연산하여 표시부(3)에 디스플레이시킨다.The control unit 5 controls the step motor 15, and also calculates and displays the distance value input from the ultrasonic transmission / reception buffer 7 on the display unit 3.

표시부(3)는 센서의 위치, 부저, 장애물 위치 표시를 한다.The display unit 3 displays the position of the sensor, the buzzer and the obstacle position.

상기와 같은 구성에 의해서 본 발명에 따른 후방 충돌 경보 장치는 다음과 같이 작동된다.By the above configuration, the rear collision warning device according to the present invention operates as follows.

도 2를 참조하면, 차량이 후진하고 있음이 판단되면(S101), 제어부(5)는 스텝 모터(15)를 구동하여 센서(13)를 좌측 끝으로 이동시킨다(S103).Referring to FIG. 2, when it is determined that the vehicle is moving backward (S101), the control unit 5 drives the step motor 15 to move the sensor 13 to the left end (S103).

그런 다음, 1차적으로 버퍼(7)와 교신하여 거리 측정을 하게 된다(S104).Then, the first communication with the buffer 7 to measure the distance (S104).

만약, 장애물이 있으면, 현재 센서의 위치 및 거리값을 저장한다(S106).If there is an obstacle, the current position and distance value of the sensor is stored (S106).

1차로 장애물 검지가 끝나면, 미리 정해진 스텝(10cm정도)으로 센서의 위치를 이동시키면서 장애물 검지를 계속 수행하면서 1차와 마찬가지로 장애물이 검지되면 센서의 위치값 및 장애물과의 거리값을 저장한다(S108).After the first detection of the obstacle, while continuing the obstacle detection while moving the position of the sensor in a predetermined step (about 10cm), if the obstacle is detected like the primary, the sensor stores the position value and the distance value with the obstacle (S108). ).

계속 검색하면서, 센서의 위치가 우측 끝에 위치하게 되면(S110), 현재 저장된 정보(거리값과 센서 위치)를 바탕으로 거리 데이터를 솔팅하여(S112), 최단 거리를 디스플레이부에 표시해주고 거리별 부저음 경보를 수행한다. 또한 센서 정보를 이용하여 장애물의 위치를 표시해 준다(S114).While searching continuously, if the position of the sensor is located at the right end (S110), the distance data is salted based on the currently stored information (distance value and sensor position) (S112), and the shortest distance is displayed on the display and the buzzer sound for each distance Perform an alarm. In addition, the position of the obstacle is displayed using the sensor information (S114).

위와같은 과정이 모두 끝나면, 다시 센서를 좌측끝으로 이동시켜서 위 과정을 계속 반복한다.After all the above steps, move the sensor to the left end again and repeat the process.

상술한 바와같이, 본 발명에 따른 후방 충돌 경보 장치는 하나의 센서만으로 후방의 장애물을 검지할 수 있으므로, 차량의 배선이 줄어들고, 하나의 센서를 후방 범퍼내에서 좌우 이동시켜 장애물을 검지하므로 검지 정밀성도 우수하다는 효과가 있다.As described above, since the rear collision warning device according to the present invention can detect the obstacle behind the vehicle with only one sensor, the wiring of the vehicle is reduced, and the obstacle is detected by moving one sensor left and right in the rear bumper to detect the accuracy. There is also an effect that is excellent.

이상에서 설명한 것은 본 발명에 따른 후방 충돌 경보 장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자가라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is just one embodiment for implementing the rear collision warning device according to the present invention, and the present invention is not limited to the above-described embodiment, and as claimed in the following claims, the gist of the present invention Without departing from the technical spirit of the present invention to the extent that any person skilled in the art to which the present invention pertains various modifications can be made.
