A rear-end collision preventing apparatus and a method of a vehicle are provided to inform a driver of the risk of a rear-end collision if distance among own vehicle and the peripheral vehicles is below a predetermined value and to record situations before/after an accident. A rear-end collision preventing apparatus of a vehicle is composed of plural cameras(11,12,13) installed at the front, rear, and lateral sides of the vehicle and equipped with distance sensors; a display unit(30) installed at the front side of the driver's seat to display an image photographed by the cameras; a control unit(20) analyzing the image obtained by the cameras and distance data and transmitting the analyzed image and distance data to the display unit; and an information input unit(26) transmitting traveling information of the vehicle to the control unit. The control unit comprises a distance measuring controller(22) calculating distance between the vehicles by using a signal transmitted from the distance sensors of the camera and a main controller(21) detecting the change of distance between the vehicles by using distance data transmitted from the distance measuring controller, judging the risk of a rear-end collision on the basis of the change of distance between the vehicles, and controlling the display unit.
