1. A back-up warning system for use in a vehicle, said warning system comprising:
- an object detection system;
an electronic control module in operative communication with said object detection system, said electronic control module capable of receiving and interpreting signals from said object detection system to determine a first value representing a distance to a target object and for generating a second value representing a rate of change of distance to said target object;
a driver alert system in operative communication with said electronic control module, said driver alert system outputting a driver alert signal as a function of said first and second value.

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 know of the imminency of a collision with the object so that the operator may react and make appropriate countermeasures.

9. A method of warning a vehicle operator of a potential collision, the method comprising the steps of:
-
generating a first value from an object detection system representing a distance to a detected object;
generating a second value associated with said detected object representing a rate of change of distance to said detected object;
generating a driver alert signal as a function of said first and second value; and
communicating said driver alert signal to a driver alert system, said driver alert signal being indicative of a time to collision with said detected object. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of alerting a vehicle operator of the imminency of a potential collision with an object while backing up, the method comprising the steps of:
-
generating a time-to-collision value associated with a detected object; and
modifying a driver alert as a function of said time-to-collision value. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
