  • Vehicular trajectory collision avoidance maneuvering method
    Patent number: 6691034
    Abstract: A collision prediction and maneuver method determines which ones of many potential target objects have a close conjunction within a gross miss distance with a subject object by trajectory propagation, then determines which one of the conjunctive objects have a high collision probability within a critical miss distance, and then determines an optimum vehicle maneuver to reduce the probability of colliding with another colliding object by determining the maneuver direction, magnitude, and time so that the least amount of propellant is consumed while avoiding potential collisions within miss distance margins. The method includes computational efficiencies in collision probability calculations using trajectory propagations and contour integrations and efficiencies in optimum avoidance maneuvering using gradient and searching computations.
