Abstract

본 발명은 자동차에 관한 것으로, 자동차가 후진하는 경우 범퍼를 손상시키지 않고 장애물과의 접촉을 감지할 수 있도록 함과 동시에 경제성 있게 설비할 수 있도록 하는 자동차의 접촉감지용 에어범퍼 시스템에 관한 것이다. 종래에는 자동차의 후방 범퍼에 에어 튜브(Air Tube)를 장착하여 범퍼의 손상을 방지하는 장치가 사용된 바 있으나, 이와 같은 방식을 사용하면 후방범퍼의 손상은 방지할 수 있을 뿐 장애물과의 접촉상태를 운전자에게 알려 줄 수 없는 문제점이 있었다. 이와 같은 문제점을 해결하기 위하여 자동차의 후바에 레이저 비임(Laser Beam)을 발사하여 장애물로부터 반사되어 되돌아 오는 레이저 비임을 감지하여 장애물의 존재를 운전자에게 알려주는 방식이 사용 된 바 있다. 그러나, 이와 같은 레이저 비임을 이용한 장애물 감지 방식은 장애물의 존재 여부를 운전자에게 알려 줄 수는 있으나 후방범퍼가 장애물과 접촉하는 경우 범퍼의 손상을 방지할 수 없고, 설치비용이 많이 소요되는 문제점이 있다. 본 발명은 자동차가 후진하는 경우 후방범퍼를 손상시키지 않고 장애물과의 접촉을 감지할 수 있고, 시스템구성이 매우 간단하여 종래의 시스템이 비하여 경제성 있게 설비할 수 있다.The present invention relates to an automobile, and relates to an air bumper system for detecting a contact of an automobile so that it is possible to economically install a contact with an obstacle without damaging the bumper when the vehicle moves backward. Conventionally, a device has been used to prevent damage to the bumper by mounting an air tube on the rear bumper of the vehicle. However, this method can prevent damage to the rear bumper but only contact with obstacles. There was a problem that can not inform the driver. In order to solve such a problem, a method of informing a driver of the presence of an obstacle by detecting a laser beam reflected from an obstacle by firing a laser beam on the rear of the vehicle has been used. However, the obstacle detection method using the laser beam can inform the driver whether the obstacle exists, but if the rear bumper comes into contact with the obstacle, the bumper can not be prevented from being damaged and the installation cost is high. . The present invention can detect the contact with the obstacles without damaging the rear bumper when the vehicle is reversing, and the system configuration is very simple and can be economically installed as compared to the conventional system.

Claims

An automobile, comprising: a pressure sensing unit 11 for detecting a change in an internal pressure of an air tube AT installed in a rear bumper 20 and outputting pressure sensing information; The controller 10 for outputting an alarm generation control signal and outputting a warning display control signal when it is determined that the pressure is increased by reading the pressure sensing information applied from the pressure detecting unit 11 and the control unit 10. A warning unit 12 generating an alarm sound for informing the driver that the rear bumper 20 is in contact with an obstacle according to an alarm generation control signal applied from the vehicle; And a display unit 13 for displaying the information to inform the driver that the rear bumper 20 is in contact with an obstacle according to a warning display control signal applied from the control unit 10. Air bumper system for contact detection in automobiles.

According to claim 1, wherein the pressure detecting unit 11 is characterized in that the pressure gauge for outputting the pressure detection information generated by detecting the internal pressure of the air tube (AT) to convert into an electrical signal to the controller 10 side. Air bumper system for contact detection of cars.
