Dynamic collision-avoidance system and method
First Claim
1. A collision-avoidance system for an aerial vehicle having a flight-control system, the collision-avoidance system comprising:
- one or more sensors to detect collision threats within a field of view of the one or more sensors of the aerial vehicle; and
a processor communicatively coupled with each of the one or more sensors;
wherein the processor is configured to generate, using at least one of said one or more sensors, obstruction data reflecting a position of a collision threat;
wherein the processor is configured to receive a navigation command from the flight-control system;
wherein the processor is configured to generate, based at least in part on the obstruction data, a derivative command by attenuating the navigation command as a function of the position of the collision threat; and
wherein the processor is configured to communicate the derivative command to the flight-control system to cause the aerial vehicle to deviate from a flight path to avoid the collision threat.

Abstract
An obstacle-avoidance system for a vehicle, the obstacle-avoidance system may comprise: a communication device; a plurality of sensors, the plurality of sensors configured to detect collision threats within a predetermined distance of the vehicle; and a processor. The processor may communicatively couple to the communication device and the plurality of sensors and configured to receive navigation commands being communicated to a control system via said communication device. The processor may also receive, from at least one of said plurality of sensors, obstruction data reflecting the position of an obstruction. Using the obstruction data, the processor identifies a direction for avoiding said obstruction. In response, the processor may output, via said communication device, a derivative command to said control system causing the vehicle to travel in said flight direction.

12. A method of navigating an aerial vehicle having a flight-control system, the method comprising the steps of:
-
detecting, via one or more sensors, collision threats within a field of view of the one or more sensors of the aerial vehicle, wherein the one or more sensors are communicatively coupled with a processor; receiving, via the processor, a navigation command from the flight-control system; generating, using at least one of said one or more sensors, obstruction data reflecting a position of a collision threat; generating, via the processor, a derivative command as a function of the obstruction data, wherein the derivative command is generated by attenuating the navigation command as a function of the position of the collision threat; and communicating the derivative command to the flight-control system to cause the aerial vehicle to deviate from a flight path to avoid the collision threat. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
