Abstract

A system for detecting objects in a blind spot of a vehicle provides detectors and/or cameras mounted at or near the top of the vehicle and at or near a center of each side of the vehicle. A camera or sensor may be provided at the top center of each side of a semi-trailer to provide a down directed view at each side of the trailer. A sensor or camera may also be provided at the top center of the back of the trailer and at or near the top of the trailer.

Claims

1. A system for detecting objects in a blind spot of a vehicle, comprising:

a trailer of a semi-tractor trailer having a trailer housing, the trailer having a coupling for connection to a tractor;

first, second and third cameras and detectors mounted adjacent to a top of the trailer and directed downwardly and outwardly from respective first, second and third sides of the trailer, the cameras and detectors being operable to detect an object within a detection zone of the cameras and detectors; and

a user interface in the tractor to provide at least one of a detector signal or a video from at least one of the first and second and third cameras and detectors upon detecting an object within the detection zone.

2. A system as claimed in claim 1, further comprising:

fourth and fifth cameras and detectors mounted on the tractor and directed downward and adjacent to the tractor, the fourth and fifth cameras and detectors being connected to transmit at least one of detector signals and video signals to the user interface.

3. A system as claimed in claim 2, wherein the fourth and fifth cameras and detectors are mounted in a mirror mount of the tractor.

4. A system as claimed in claim 1, wherein the cameras and detectors include video cameras.

5. A system as claimed in claim 4, wherein the user interface includes a video display screen.

6. A system as claimed in claim 1, wherein the cameras and detectors include object detectors.

7. A system as claimed in claim 6, wherein the user interface includes an indicator that operates to indicate an object detected in the detection zone.

8. A system as claimed in claim 1, wherein the first and second cameras and detectors are mounted adjacent a top of the trailer approximately midway along opposite sides of the trailer.

9. A method for detecting objects adjacent to a tractor trailer, comprising:

directing a plurality of cameras and detectors from a top of a trailer to a plurality of detection zones disposed adjacent to the trailer, the detection zones extending from adjacent to the trailer outward a predetermined distance, the detection zones extending for at least a full length of the trailer;

detecting an object in at least one of the detection zones; and

alerting a driver of the tractor trailer of the detection of the object.
