Abstract
Official abstract text for this publication.
A radar object detection system includes a radar sensor and a controller. The radar sensor is configured to emit a radar signal toward a defined area proximate to the vehicle, and output a reflection signal indicative of a detected target present in the defined area. The controller is configured to receive the reflection signal from the radar sensor, determine if the detected target corresponds to a trailer towed by the vehicle, and define an exclusion zone characterized as occupied by the trailer and thereby excluded from the defined area where objects can be detected.
First claim
Opening claim text (preview).
We claim: 1. A radar object detection system configured to detect objects proximate to a vehicle, said system comprising; a radar sensor configured to emit a radar signal toward a defined area proximate to the vehicle, and output a reflection signal indicative of a detected target present in the defined area; a controller configured to receive the reflection signal from the radar sensor, determine if the detected target corresponds to a trailer towed by the vehicle, and define an exclusion zone characterized as occupied by the trailer and thereby excluded from the defined area where objects can be detected, wherein the controller is configured to determine if the detected target corresponds to the trailer only when a present speed of the vehicle is greater than a speed threshold. 2. The system in accordance with claim 1 , wherein the detected target corresponds to the trailer if a range to the detected target varies less than a variation threshold for greater than a time threshold. 3. The system in accordance with claim 1 , wherein the detected target corresponds to the trailer if a range to the detected target is less than a maximum distance threshold. 4. The system in accordance with claim 1 , wherein a length of the exclusion zone is determined based on a longitudinal distance to a most-distant target that corresponds to the trailer and is closer than a maximum trailer length. 5. The system in accordance with claim 1 , wherein a width of the exclusion zone is determined based on a lateral distance between a left-most target that corresponds to the trailer and a right-most target that corresponds to the trailer.
