1. A rear warning system employing an outside mirror of a vehicle comprising:
- a reverse switch operating unit for operating a reverse gear transmission used when moving a vehicle backward and park the vehicle;
an ultrasonic sensor installed on the rear bumper of the vehicle for determining an object existing behind the vehicle and detecting distance between the rear end of the vehicle and the object;
a main controller for controlling the ultrasonic sensor when the reverse switch operating unit is manipulated; and
an outside mirror comprising a frame and a mirror supported by the frame, in which the angle of the outside mirror is adjusted by the main controller and the outside mirror has an LED display and a distance indicator provided on the frame for indicating the distance between the rear end of the vehicle and the object in multiple steps, wherein while the vehicle is moved forward, the LED display and the distance indicator are positioned inside the mirror, whereas while the vehicle is moved backward and parked, the LED display and the distance indicator are positioned outside the mirror.

Abstract
Disclosed is a rear warning system employing an outside mirror of a vehicle. When a driver moves a vehicle backward and parks the vehicle, the rear warning system warns a driver that the vehicle approaches a person or an obstacle existing behind the vehicle and provides the driver with a visual indication of the distance between the rear end of the vehicle and the person or the obstacle, so that a vehicular collision can be prevented and the vehicle can be stopped or parked at an exact distance, thereby enhancing the convenience in driving the vehicle.
