Vehicle zone detection system and method
First Claim
1. An object detection system for detecting an object in a zone proximate to a host vehicle, said system comprising:
- a first infrared detector adapted to be located on a host vehicle and configured to sense temperature of a first coverage zone proximate to the host vehicle by receiving infrared radiation from the first coverage zone;
a processor for processing the temperature sensed by the first infrared detector, wherein the processor determines a change in temperature sensed by the first infrared detector and determines the presence of an object in the first coverage zone based on the determined change in sensed temperature; and
an output for outputting a signal indicative of an object sensed in the first coverage zone based on the determined change in temperature.

Abstract
An object detection system is provided for detecting a thermal emitting object in a blind zone proximate to a host vehicle. The system includes a thermal radiation detector located on a host vehicle and configured to sense temperature of multiple coverage zones proximate to the host vehicle. A processor processes temperature sensed by an infrared detector. The processor determines a change in thermal temperature sensed by the infrared detector and determines the presence of an object in the coverage zone based on the change in the sensed temperature. An output provides a signal indicative of an object sensed in the coverage zone based on the determined change in temperature. The thermal radiation detector may include a first infrared detector configured to measure temperature of a first coverage zone by receiving infrared radiation from the first coverage zone, and a second infrared detector configured to measure temperature of second and third coverage zones by receiving infrared radiation from the second and third coverage zones.
