Abstract

본 발명은 트럭, 버스등과 같은 대헝차량이 후진할 경우 운전자가 후방을 완전히 감시할 수 없어 발생하는 사고를 방지하기 위하여 자동차 후방에 장애물이 있을 경우 이를 운전자에게 경고음을 통하여 청각적으로 알려주는 후방 장애물 경보장치에 관한 것으로, 자동차 후미에는 자동차 후방의 장애물을 감지하기 위하여 초음파 송신기 및 초음파 수신기를 설치하고, 또한 자동차에 후진기어가 작동하는 지를 감지하는 후진기어 감지 센서를 설치하여, 자동차의 후진기어가 작동하면 마이컴이 이를 감지하여, 상기 초음파 송신기를 통하여 자동차 후방의 사각지대로 초음파를 송출하게 하고 상기 초음파 송출기를 통하여 송출된 초음파를 수신함으로써 후방에 장애물이 있는지를 검출하며, 후방에 장애물이 있을 경우 부저를 통하여 경보음을 발생시켜 운전자에게 후방에 장애물이 존재함을 청각적으로 알리는 효과가 있다.According to the present invention, when a large vehicle such as a truck or a bus moves backward, the driver may not be able to completely monitor the rear, and the driver may acoustically notify the driver through an alarm sound when there is an obstacle in the rear of the vehicle. It relates to an obstacle warning device, and in the rear of the car, an ultrasonic transmitter and an ultrasonic receiver are installed to detect an obstacle behind the car, and a reverse gear detection sensor is installed in the car to detect whether the reverse gear is operated. When is activated, the microcomputer detects this and transmits the ultrasonic waves to the blind spot behind the vehicle through the ultrasonic transmitter and detects the obstacles in the rear by receiving the ultrasonic waves transmitted through the ultrasonic transmitter. When alarm sounds through buzzer The effect to the driver audibly announce the existence of obstacles to the rear.

Description

Rear obstacle alarm
