Abstract: PURPOSE: A rear-end collision warning device and a waning method thereof are provided to show a driver the image of an obstacle and indicate the distance and the position of the obstacle at the same time by interlocking with an AV(audio-visual) system and a CCD(charge coupled device) camera. CONSTITUTION: To warn a driver of a rear-end collision, a system stores the display information of a prior image with a backup signal and restructures the image of a display unit to a rear image window and a level meter widow. Then, the system receives image signals form a CCD camera and displays the image signals on the rear image window. Plural supersonic sensors measure a distance between a vehicle and an obstacle, and the system stores distance information per sensor position and classifies the distance information per size. When the distance information is less than a predetermined value, an alarm sound is generated through a buzzer and the stored distance information is indicated on the level meter window of the display unit. After finishing the backup signal, the screen is restored.
