Abstract

A method for avoiding collisions with an aircraft ground-services vehicle includes using a proximity sensor attached to the ground-services vehicle to generate a proximity signal, and using a processor that stores a three-dimensional map of the ground-services vehicle'"'"'s outer geometry. The three-dimensional map is modifiable upon in-use changes to the 3-D geometry of the ground-services vehicle. The processor uses the three-dimensional map and the proximity signal to determine whether a predetermined 3-D envelope around the vehicle has been breached, and notifies the vehicle of a breach.

Claims

1. A method of avoiding collisions between a ground vehicle and a stationary aircraft, the vehicle including movable elements that change an outer geometry of the vehicle, the method comprising:

changing the outer geometry of the vehicle;

sensing the proximity of the aircraft to the vehicle;

utilizing a digital map of three-dimensional outer dimensions of the ground vehicle, the map changing to describe the changes in the geometry of the vehicle, wherein utilizing the map includes comparing the dimensions in the map to the proximity of the aircraft to determine when the aircraft is within a predetermined envelope around the outer dimensions of the ground vehicle; and

activating a brake mechanism to automatically engage a ground vehicle brake when the aircraft is within the predetermined envelope.

2. The method of claim 1, further comprising sensing the vehicle proximity to an airport gate area, wherein the brake mechanism is activated within a predetermined proximity to the gate area.

3. The method of claim 2, wherein sensing the vehicle proximity to the gate area includes receiving a global positioning system signal of vehicle location.

4. The method of claim 1, further comprising detecting a direction vector and velocity of the ground vehicle;

wherein activation of the brake mechanism is modified based on the detected velocity.

5. The method of claim 1 wherein the proximity is sensed with a first global positioning system attached to said ground services vehicle;

wherein a second global positioning system is aboard the aircraft, and wherein signals from the first and second global positioning systems are compared to determine when the aircraft is within the predetermined envelope.

6. A method for avoiding collisions with an aircraft ground-services vehicle, the method comprising:

using a proximity sensor attached to the ground-services vehicle to generate a proximity signal; and

using a processor that stores a three-dimensional map of the ground-services vehicle outer geometry, the three-dimensional map modifiable upon in-use changes to the 3-D geometry of the ground-services vehicle;

wherein the processor uses the three-dimensional map and the proximity signal to determine whether a predetermined 3-D envelope around the vehicle has been breached, and notifies the vehicle of a breach.

7. The method of claim 6, further comprising engaging brakes on the ground-services vehicle when the envelope is breached.

8. The method of claim 7, wherein the brakes are engaged when the ground-services vehicle is in a pre- designated aircraft terminal gate area.

9. The method of claim 6, wherein the proximity sensor includes a global positioning system aboard the ground-services vehicle;

wherein a global positioning system is aboard an aircraft; and

wherein the processor uses signals from both global positioning systems to determine distance between the ground-services vehicle and the aircraft.

10. The method of claim 6, wherein the processor receives signals of vehicle geometry changes in use, and modifies the three-dimensional map upon receiving the geometry changes.
