1. A vehicle rear warning system, comprising:
a driving information detection portion that collects information measured from a radar and a camera sensor in a reverse mode of a vehicle;
a controller that separates a danger zone and a safe zone with reference to a fixed obstacle at a rear of the vehicle by performing fusion of the information measured from the radar and the camera in the reverse mode of the vehicle, and generates a collision event and controls warning and braking when a moving object approaching from the danger zone is detected, while limiting the warning and braking for the moving object existing in the safe zone;
a braking portion that generates a braking force to wheels according to a control signal applied from the controller;
a warning portion that warns a driver of a rear collision event of the vehicle and displays a braking state accordingly; and
a storing portion that matches and stores reference coordinates for measuring coordinates of an object with reference to the vehicle through the radar and the camera.
