Patent ID: 8566027

Claim:
A route re-planning system comprising: a processor disposed onboard a vehicle and coupled to a nontransitory computer readable medium bearing software instructions that, when executed by the processor, cause the processor to perform operations including: receiving an original mission plan and threat location data at the processor, the threat location data being received wirelessly at the vehicle from a location remote from the vehicle during execution of the original mission plan; comparing threat location data to a stored time/space threat, the stored time/space threshold including a threshold geographical area boundary, threshold and determining, based on the comparison, whether a moving threat location has moved outside or moved within the threshold geographical area boundary; when a threat location has moved within the threshold geographical area boundary, the original mission plan including the original route for the vehicle is maintained; when the threat location has moved outside the threshold geographical area boundary, performing steps including: assessing own force survivability and generating a reflexive response signal when own force is in immediate danger; generating, with the processor, new threat movement predictions; performing an updated multi-point survivability analysis with the processor using the new threat movement predictions as input, the multi-point survivability analysis including generating a new time/space threshold for the threat at each of a plurality of predetermined time in a mission timeline and including determining the lethality of a threat at a plurality of locations; determining, with the processor, whether a current mission plan is survivable based on the updated multi-point survivability analysis; and when the original mission plan is not survivable, generating a new mission plan including a re-planned route for the vehicle, the re-planned route being a different route than an original route associated with the original mission plan.
