Abstract

The system includes a detector display having visual indicators arranged in a pattern representing a monitored area near the vehicle desired to be monitored. The visual indicators represent physical locations within the monitored area. An indicator controller is operatively associated with the detector display for actuating the visual indicators to display an object location in the pattern that corresponds to the location of an object in the monitored area. A proximity sensor is included in communication with the indicator controller for detecting the physical location of objects within the monitored area. A detection signal is transmitted by the proximity sensor to the indicator controller in response to detecting an object, wherein the indicator controller is operable to actuate the visual indicators in response to the detection signal to display an object location in the pattern that corresponds to an object location in the monitored area.

Claims

1. A collision avoidance display system for a vehicle comprising:

a detector display having a plurality of visual indicators arranged in a pattern on said display representing a defined monitored area along a first side of the vehicle, wherein each of said visual indicators on said display represents a distinct physical location within said monitored area;

an indicator controller operatively associated with said detector display for actuating said visual indicators to display an object location in said pattern that corresponds to a physical location of an object within said monitored area;

a proximity sensor having a total physical area of sensor coverage defining the physical limit of said proximity sensor to detect an object, wherein said total physical area of sensor coverage defines said monitored area and said proximity sensor that is in communication with said indicator controller for detecting said physical location of said object within said monitored area, wherein said pattern of said visual indictors indicators in said display is arranged to render to a driver said total physical area of sensor coverage defining said monitored area in specific relation to said first side of the vehicle so that said display shows the physical limit of said proximity sensor to detect an object next to the vehicle;

a detection signal being transmitted by said proximity sensor to said indicator controller in response to detecting said object, wherein said indicator controller is operable to actuate said visual indicators in response to said detection signal to display said object location in said pattern that corresponds to said physical location of said object in said monitored area; and

,

wherein said indicator controller actuates said visual indicators to display movement forward, back, left and right of at least one said object throughout the entire said monitored area relative to the vehicle in response to said detection signal from said proximity sensor.

2. The display system of claim 1 wherein said pattern of said visual indicators on said display includes a plurality of monitoring zones each corresponding in physical configuration to one said monitored areas area adjacent the vehicle.

3. The display system of claim 2 wherein said plurality of monitoring zones on said display include a left side monitoring zone and a right side monitoring zone wherein a plurality of said visual indicators are arranged in each said monitoring zone representing the physical configuration of a left side monitored area and a right side monitored area on opposing sides of the vehicle, respectively.

4. The display system of claim 3 including a left proximity sensor covering said left side monitored area with an array of object detection beams for detecting the physical location of said object within said left side monitored area, wherein each of said visual indicators in said left side monitoring zone is correlated with at least one of said object detection beams so that detection of said object by one of said object detection beams signals said indicator controller to actuate a correlated one of said visual indicators;

and,

a right proximity sensor covering said right side monitored area with an array of object detection beams for detecting the physical location of said object within said right side monitored area, wherein each of said visual indicators in said right side monitoring zone is correlated with at least one of said object detection beams so that detection of said object by one of said object detection beams signals said indicator controller to actuate a correlated one of said visual indicators, whereby the location of said object in said left side and right side monitored areas can be displayed in said left and right side monitoring zones.

5. The display system of claim 4 wherein said plurality of monitoring zones on said display include a front monitoring zone and a back monitoring zone wherein a plurality of said visual indicators are arranged in each said monitoring zone representing the physical configuration of a front monitored area and a back monitored area on opposing ends of the vehicle, respectively.

6. The display system of claim 5 including a front proximity sensor covering said front monitored area with an array of object detection beams for detecting the physical location of said object within said front monitored area, wherein each of said visual indicators in said front monitoring zone is correlated with at least one of said object detection beams so that detection of said object by one of said object detection beams signals said indicator controller to actuate a correlated one of said visual indicators;

and,

a back proximity sensor covering said back monitored area with an array of object detection beams for detecting the physical location of said object within said back monitored area, wherein each of said visual indicators in said back monitoring zone is correlated with at least one of said object detection beams so that detection of said object by one of said object detection beams signals said indicator controller to actuate a correlated one of said visual indicators, whereby the location of said object in said front and back monitored areas can be displayed in said front and back monitoring zones.

7. The display system of claim 2 wherein said plurality of monitoring zones on said display include a front monitoring zone and a back monitoring zone representing the physical configuration of a front monitored area and a back monitored area, respectively.

8. The display system of claim 2 wherein said detector display includes a vehicle outline around which said plurality of monitoring zones are arranged for orienting the physical location represented by each of said monitoring zones in relation to the vehicle.

9. The display system of claim 2 wherein said visual indicators in said plurality of monitoring zones are shaped in the form of round dots.

10. The display system of claim 2 wherein said visual indicators in said plurality of monitoring zones are shaped in a form selected from one of triangular and rectangular block segments, and combinations thereof.

11. The display system of claim 1 wherein said proximity sensor includes a beam emitter for emitting light beams into said monitored area for detecting said object, and wherein said pattern of said visual indicators is correlated to represent the physical configuration of the monitored area covered by said beams.

12. The display system of claim 11 wherein said visual indicators are operatively associated with at least one selected light beam so that detection of said object by one of said light beams signals said indicator controller to actuate at least one designated visual indicator corresponding to said light beam.

13. The display system of claim 11 wherein said proximity sensor includes a photodetector for detecting light from said light beams being reflected by said object in said monitored area, and wherein said photodetector generates said detection signal for transmission to said indicator controller.
