  • Patent number: 11592843
    Abstract: A technique relates to autonomous obstacle avoidance. A vehicle is controlled on a route to a destination, the route being a three-dimensional route. An obstruction is determined on the global route. A local route including alternate points to avoid the obstruction is autonomously determined. The local route is autonomously converged back to the global route in response to avoiding the obstruction.

  • Publication number: 20220269290
    Abstract: A technique relates to route planning. Points associated with a start location and a destination location are received. It is determined whether the points comprise one or more hard points, one or more soft points, or both. At least one obstruction to avoid is determined. A route is autonomously generated comprising the points and segments associated with the points, the segments comprising rhumb lines, great-circle arcs, or both. Responsive to the points comprising the one or more soft points, the at least one obstruction is avoided by permitting a distance associated with the one or more soft points to be reached and adding at least one free waypoint. Responsive to the points comprising the one or more hard points, the at least one obstruction is avoided by requiring the one or more hard points to be reached and adding the at least one free waypoint.

  • Patent number: 10216186
    Abstract: A system and method for flying an aircraft is disclosed. The system includes one or more flight-assist agents for performing an operation related to flying the aircraft and a vehicle autonomy management system. The vehicle autonomy management system allocates tasks of a task workload involved in the operation between a flight crew and the one or more flight-assist agents, monitors a performance of the flight crew in executing a portion of the task workload allocated to the flight crew, and adjusts an allocation of the task workload between the flight crew and the one or more flight-assist agents based on the performance of the flight crew.

  • Publication number: 20180114199
    Abstract: A processing system for displaying a task sharing and scheduling interface includes: at least one assist agent to perform tasks; an autonomy management module to decompose a mission into the tasks and to allocate the tasks between at least one user and at least one assist agent; a display to display the task sharing and scheduling interface to the at least one user on a display and to receive input from the at least one user, wherein the interface comprises an agent region and a user region, wherein the agent region comprises indicia of tasks allocated to the at least one assist agent, wherein the user region comprises indicia of tasks allocated to the at least one user, and wherein the at least one assist agent performs at least one of the tasks allocated to the at least one assist agent.
