Abstract

본 발명은 자동차 주행 중에 일반 사이드 미러(0/SIDEMIRROR)의 구조 및 형상으로는 자신의 자동차의 사각지대로 근접하는 자동차를 감지 하지 못하여 차선 변경 시 접촉사고가 발생하는 것을 방지하기 위하여 자동차의 사이드 미러에 초음파 감지 센서를 설치하여 사각지대로 접근하는 자동차가 있으면 경보음을 발생시켜 운전자에게 알려줌으로써 안전사고를 미연에 방지하는 사각지대 내의 물체 감지 장치에 관한 것으로, 자동차측면의 사각지대 내의 장애물을 감지하기 위하여 자동차 사이드 미러의 좌측 및 우측에 좌측 초음파 송수신기 및 우측 초음파 송수신기를 설치하고, 또한 자동차의 방향지시기가 좌측 또는 우측을 지시하는지를 감지하는 방향지시기 감지 센서를 설치하여, 자동차의 방향지시기가 작동하면 마이컴이 이를 감지하여 해당하는 상기 초음파 송수신기를 통하여 자동차측면의 사각지대로 초음파를 송출하게 하고 물체에 반사되어 돌아오는 초음파를 수신함으로써 자동차 측면의 사각지대에 장애물이 있는지를 검출하며, 자동차 측면의 사각지대에 장애물이 있을 경우 부저를 통하여 경보음을 발생시켜 운전자에게 측면의 사각지대에 장애물이 존재함을 청각적으로 알리는 효과가 있다.The present invention does not detect a vehicle approaching the blind spot of its own vehicle by the structure and shape of a general side mirror (0 / SIDEMIRROR) while driving a vehicle to prevent contact accidents when changing lanes The present invention relates to an object detecting device in a blind spot that prevents a safety accident by generating an alarm sound and informing a driver when there is an automobile approaching the blind spot by installing an ultrasonic sensor in the blind spot. In order to install the left and right ultrasonic transceiver and the right ultrasonic transceiver on the left and right side of the car side mirror, and to install the direction indicator sensor for detecting whether the direction indicator of the car indicates the left or right side, Microcomputer detects this and It detects whether there is an obstacle in the blind spot on the side of the car by sending an ultrasonic wave to the blind spot on the side of the car through the ultrasonic transceiver and receives the ultrasonic wave reflected from the object. By generating an alarm sound through the driver has an effect of audibly notifying the presence of obstacles in the blind spot on the side.

Claims

The detection sensor 100 detects whether the direction indicator of the vehicle indicates the direction of the left or the right, and receives the ultrasonic waves that are sent back and reflected back to the object to detect the obstacle of the blind spot on the left side of the vehicle The left ultrasonic transceiver 200 detects whether there is an obstacle in the left blind spot of the vehicle and the right blind spot of the vehicle by transmitting an ultrasonic wave to detect an obstacle in the blind spot of the right side of the vehicle and returning ultrasonic waves reflected back to the object. The right ultrasonic transceiver 300 for detecting whether there is an obstacle, the direction indicating sensor 100, the left ultrasonic transceiver 200 and the right ultrasonic transceiver 300 is connected to the ultrasonic transceiver (200, 300) B) from the buzzer control unit A microcomputer (400) for sending a call, and a relay (RL1) in which a contact is turned on in accordance with a control signal of the microcomputer (400). The object detection device in the blind spot, characterized in that consisting of a buzzer (500) for generating an alarm sound when the power is supplied as the contact point of the relay (RL1) is turned on.
