SYSTEM AND METHOD FOR DETECTING REMOTE INTRUSION OF AN AUTONOMOUS VEHICLE BASED ON FLIGHTPATH DEVIATIONS
Systems, methods, and computer-readable storage media for retrieving, for an autonomous vehicle which is moving, a navigation path from a memory device in communication with a processor. The system generates a navigation path range based on the navigation path, the navigation path range allowing a threshold distance from the navigation path, and identifying a current location of the autonomous vehicle. The system also determines that the current location of the autonomous vehicle is outside the navigation path range, sends a request to the autonomous vehicle for a list of reasons for the navigation path distinction, and receives (from the autonomous vehicle) the list of reasons for the navigation path distinction. The system compares the list of reasons to a list of acceptable causes for the autonomous vehicle to not be within the navigation path range and determines that an intrusion attempt on the autonomous vehicle is being made.
1 . A method comprising:
retrieving, at a central location for an autonomous vehicle which is moving, a planned navigation path from a memory device in communication with a processor;
generating, via the processor, a navigation path range based on the planned navigation path, the navigation path range allowing a threshold distance from the planned navigation path;
identifying a current location of the autonomous vehicle;
determining, via the processor, that the current location of the autonomous vehicle is outside the navigation path range, to yield a navigation path distinction;
sending a request to the autonomous vehicle for a list of reasons for the navigation path distinction;
receiving, from the autonomous vehicle, the list of reasons for the navigation path distinction;
comparing, via the processor, the list of reasons to a list of acceptable causes for the autonomous vehicle to not be within the navigation path range, to yield a comparison; and
