Abstract
A warning system that warns an operator of an impending collision with an object while the operator is backing up. The system scans behind the vehicle with an emitter/sensor system and determines a time-to-collision with the object based on distance to the object and vehicle speed. Based upon the time-to-collision, a simple combination of visual and audio signals is designed to let the operator known of the imminency of a collision with the object so that the operator may react and make appropriate countermeasures.
