Description

운전자의 후방시야 사각지대 제거장치{A removing dead rear view system for driver}A driver's rear view blind spot removal device {A removing dead rear view system for driver}

본 발명은 운전자의 후방시야 사각지대 제거장치에 관한 것으로, 보다 상세하게는 운전자가 보이지 않는 후방상태를 영상으로 보면서 차량을 후진할 수 있어 안정성을 확보할 수 있도록 된 차량의 운전자의 후방시야 사각지대 제거장치에 관한 것이다.The present invention relates to a device for removing the rear view blind spot of the driver, and more particularly, the rear view blind spot of the driver of the vehicle, which can secure the stability by reversing the vehicle while viewing an image of the rear view invisible to the driver. It relates to a removal device.

일반적으로, 차량에는 차량 후방의 상태를 운전자에게 보여줄 수 있도록 운전자를 중심으로 즉, 차량 실내의 중앙 상부부위로 후방을 보여주도록 부착된 룸미러와, 차량의 운전석과 조수석의 측면으로 각각 구비되어 측면후방을 보여주도록 구비된 사이드미러등을 부착하게 되지만, 이러한 룸미러와 사이드미러를 통한 운전자의 후방시야 확보에는 그 구조상 시야 확보에 대한 한계가 있게 되어 특히, 주차를 하기 위해서나 후진을 하는 경우 위와 같은 후방시야 확보용 미러들을 통해서도 전혀 볼 수 없는 시야 사각지대가 존재하게 되는 문제가 있게 된다.In general, the vehicle is provided with a rearview mirror attached to the driver to show the driver behind the vehicle, that is, to show the rear of the center of the vehicle interior, and the sides of the driver's seat and the passenger seat of the vehicle. The rearview mirror provided to show the rear is attached, but the rear view of the driver through the rearview mirror and the rearview mirror has a limitation in securing the view of the structure, especially when parking or reversing the above. There is a problem that there is a blind spot that can not be seen at all even through the rear view mirrors.

근래에 들어 이와 같은 문제를 극복하기 위해 차량의 후방상태를 초음파등을 보내 물체가 감지되면 운전자에게 경고하여 주는 후방 물체 감지장치등을 사용하고는 있지만, 이러한 감지장치도 후방상태를 운전자가 영상으로 인식하지 못해 특히, 영상을 통한 시야확보가 필요한 대형 차량이나 초보운전자의 경우 사각지대의 시야확보에 도움을 주지 못하는 단점이 있게 된다.Recently, in order to overcome this problem, a rear object detector is used to send an ultrasonic lamp to the rear of the vehicle to warn the driver when an object is detected. Since it is not recognized, especially for a large vehicle or a novice driver who needs to secure the field of view through the image, there is a disadvantage that does not help to secure the blind spot.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 선택적으로 사용되는 카메라를 이용하여 차량의 주행이나 후진등에 따른 후방의 상태를 운전자가 영상으로 인식하여 차종에 관계없이 후방시야의 사각지대를 제거함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above, and the driver recognizes the rear state according to the driving or reversing of the vehicle as an image using an optional camera, thereby recognizing the blind spot of the rear view regardless of the vehicle type. Its purpose is to eliminate it.

상기와 같은 목적을 달성하기 위한 본 발명은, 차량의 상태 즉, 후진이나 좌·우회전등을 인식하도록 신호를 발생하는 상태신호입력부와, 이 상태신호입력부에연동되어 영상신호를 발생하는 영상신호입력부, 이 입력부의 신호를 처리하는 제어기 및 이 제어기의 신호에 따라 영상을 보여주는 모니터로 구성되되, 상기 모니터는 제어기로 전송되는 온·오프용 모니터스위치의 신호에 따라 작동되도록 구성되는 것을 특징으로 한다.The present invention for achieving the above object, the state signal input unit for generating a signal for recognizing the state of the vehicle, that is, backward, left, right turn, etc., and the video signal input unit connected to the state signal input unit to generate a video signal And a controller for processing a signal of the input unit and a monitor showing an image according to the signal of the controller, wherein the monitor is configured to operate according to a signal of an on / off monitor switch transmitted to the controller.
