ABSTRACT:
An automotive rear detection system which assists a driver by informing whether an obstacle is present when the vehicle is in a reverse motion. The alarm is activated by transmitting an audible noise to warn the driver. The signals are monitored by detectors which uses frequency modulation current wave mode to recognize whether objects are present within approximately eight feet regardless if it is in motion or not. The detectors send a signal to a control box mounted inside the vehicle which activates the alarm.
