    摘要: According to an aspect of the invention, a method of optimal safe landing area determination for an aircraft includes accessing a probabilistic safe landing area map that includes a plurality of probabilistic indicators of safe landing areas for the aircraft. A processing subsystem that includes one or more processing resources generates a list of candidate safe landing areas based on the probabilistic safe landing area map and one or more constraints. At least two of the candidate safe landing areas are provided to a path planner. The list of candidate safe landing areas is ranked based on results from the path planner indicating an estimated cost to reach each of the candidate safe landing areas. Based on the ranking, an indicator of an optimal safe landing area is output as a desired landing location for the aircraft.

    摘要: A system and method for identifying a slung load for an aircraft with one or more sensors includes receiving, with a processor via one or more sensors, sensor information related to flight dynamics data for the aircraft; determining, with the processor, control input commands for the aircraft in response to the receiving of the flight dynamics data; determining, with the processor, signals indicative of an estimated pendulum frequency; and determining, with the processor, parameters associated with the slung load in response to the determining of the estimated pendulum frequencies.

    摘要: An aspect includes space partitioning for vehicle motion planning. A plurality of obstacle data is analyzed to determine a plurality of obstacle locations in a configuration space of a vehicle. A partitioning of the configuration space is performed to compute a skeletal partition representing a plurality of obstacle boundaries based on the obstacle locations. The skeletal partition is used to preferentially place a plurality of samples by a sampling-based motion planner. At least one obstacle-free path is output by the sampling-based motion planner based on the samples.

    摘要: An aspect includes a method of kinematic motion planning includes accessing a list of a plurality of nodes defining a plurality of potential kinematic path locations between a starting position and an ending position of a vehicle. A plurality of constraint sets is determined that apply one or more vehicle motion constraints based on a plurality of spatial regions defined between the starting position and the ending position. The constraint sets are applied in determining a plurality of connections between the nodes to form a kinematic motion path based on locations of the nodes relative to the spatial regions. The kinematic motion path is output to a dynamic path planner to complete creation of a motion path plan for the vehicle.

    摘要: A method of trajectory control for a vehicle includes obtaining an initial trajectory; presenting the initial trajectory as a current trajectory on an I/O device, the current trajectory presented overlaying terrain; initiating travel of the vehicle along the current trajectory; updating the current trajectory and the terrain in real time as the vehicle travels along the current trajectory; determining if change in the current trajectory is required; changing the current trajectory to an altered trajectory in response to determining change in the current trajectory is required; and presenting the altered trajectory on the I/O device, the altered trajectory presented overlaying the terrain.
