Abstract

본 발명은 자동차의 후방물체를 자동감지하는 차량후방 감지장치에 대한 것으로, 송신부(100)와 수신부(200)의 사이에 검파된 수신파와 기준신호를 비교하여 기준신호보다 큰 수신신호를 출력하는 비교회로(7)와 신호반전회로(8)를 설치함과 동시에 소정의 프로그램을 갖는 마이컴(9)을 설치하여 차량의 후진주차시 물체감지거리가 LED 점등회로(11)를 통해 구분표시되도록하고, 또한 거리표시회로(12)를 통해 1, 2, 3차의 거리가 수치로 표시되도록 하여 근접주차가 가능토록 하는 한편, 후방주행차량이 일정거리 접근시 비상등점등회로(13)를 통해 비상등의 경고점멸이 실시되도록 하여 후미차량에 대하여 주의를 요하도록 하는 등 차량안전사고에 커다란 일익을 담당할 수 있는 신규의 발명이다.The present invention relates to a rear vehicle detecting apparatus for automatically detecting a rear object of a vehicle, and compares a received signal and a reference signal detected between the transmitter 100 and the receiver 200 to output a received signal larger than the reference signal. By installing the circuit 7 and the signal inversion circuit 8 and the microcomputer 9 having a predetermined program, the object sensing distance is displayed separately through the LED lighting circuit 11 when the vehicle is parked backward. In addition, the distance display circuit 12 displays the distance of the 1st, 2nd and 3rd cars in numerical value so that close parking is possible, while warning of emergency light through the emergency light circuit 13 when the rear driving vehicle approaches a certain distance. It is a novel invention that can play a big role in vehicle safety accidents, such as causing the flicker to be carried out, requiring attention to the rear vehicle.

Claims

In constructing a rear vehicle sensing apparatus in which rear object sensing is performed by installing an ultrasonic transceiver (TX) (RX) at the rear of the vehicle, a transmission signal oscillation circuit (1), a transmission signal amplification circuit (2), and a transmitter (TX) Detection output from the detection circuit (5) between the transmitter (100) consisting of a receiver (RX), the reception signal primary amplification circuit (4), and the detection unit (200). Comparing the reference signal output from the reference waveform output circuit 6 of the received reception wave and outputting a reception signal larger than the reference signal 7 and the signal inversion circuit 8 and having a predetermined program The microcomputer 9 is installed so that the object detection distance is separately displayed through the LED lighting circuit 11 when the vehicle is parked backward, and the distances of the first, second and third cars are displayed numerically through the distance display circuit 12. To allow close parking, while driving behind the wheel at a certain distance (6m to 5m). Detecting the rear of the vehicle characterized in that the approach warning instruction is made so that the three flashing of the emergency light is carried out through the myopia emergency light circuit (13).
