  • Patent number: 11454517
    Abstract: A system and to a method of analyzing and monitoring interfering movements of an inertial unit of an aircraft during a stage of statically aligning the inertial unit. During the static alignment stage, measurements of the velocity of the aircraft relative to the ground are acquired, and states of a mirror process having a model that is close to the model of the process of aligning the inertial unit are estimated. The states of the mirror process are estimated from observations constituted by the measurements of velocity relative to the ground. Finally, the estimates of the states are compared with respective validation thresholds in order to validate or not validate said alignment of the inertial unit.

  • Patent number: 11307584
    Abstract: A technique is described for developing and using applications and skills with an autonomous vehicle. In an example embodiment, a development platform is provided that enables access to a developer console for developing software modules for use with an autonomous vehicle. Using the developer console, a developer user can specify instructions for causing an autonomous vehicle to perform one or more operations. For example, to control the behavior of an autonomous vehicle, the instructions can cause an executing computer system at the autonomous vehicle to generate calls to an application programming interface (API) associated with an autonomous navigation system of autonomous vehicle. Such calls to the API can be configured to adjust a parameter of a behavioral objective associated with a trajectory generation process performed by the autonomous navigation system that controls the behavior of the autonomous vehicle.

  • Patent number: 11275385
    Abstract: The driving support device executes self-position estimation of an own vehicle by odometry. In the case where landmarks around the own vehicle are detected, the driving support device corrects the self-position and creates an environment map. Next, the driving support device estimates the correction accuracy of the estimated self-position. In the case where the correction accuracy is high, the driving support device selects a first operating mode of driving support. In the case where the correction accuracy is low and the accuracy of odometry is also low, the driving support device selects a second operating mode of driving support. The second operating mode is a mode in which the degree of driving support is lower than that in the first operating mode.

  • Patent number: 10960971
    Abstract: An automatic yaw enhancement method for an aircraft having at least one propeller includes providing to a flight controller a pilot command from a pilot interface and avionic data for an airspeed, an angle of attack, and a thrust. A P-factor compensation is determined based on one or more of the airspeed, the angle of attack, and the thrust. A command to a trim device is determined based on a P-factor compensation. When a rudder bias persists, the command to the trim device is repeatedly updated until a rudder force input is nullified. The methods provide automatic pilot assistance for controlling yaw during asymmetric flight conditions and automatic turn coordination while allowing intentional side-slip for facilitating crosswind landings.

  • Patent number: 10814842
    Abstract: A braking system and method utilizing a simplified estimate of a distance between two locations on the earth based on spherical geometry. A braking system utilizing the aforementioned simplified estimate does not require computationally intensive calculations and is more efficient and better equipped to handle real-time generation of distance estimates for braking needs and variable conditions. In the present invention, geodesics evaluations are not used; rather, a modified Haversine formula that simplifies computations is used, including a one-time computation of the cosine of latitude coordinate.

  • Patent number: 10692389
    Abstract: Methods and systems may allow for automatic initiation of a contingency maneuver, to prevent mid-air collisions between an aerial vehicle and another aircraft or other obstacle, without requiring input from an operator. Generally, a processing unit on board the aerial vehicle detects potential conflicts via a navigation system on board the aerial vehicle. Said navigation system may receive, for example, automatic dependent surveillance-broadcast (ADS-B) signals and global positioning system (GPS) data. Disclosed systems automatically initiate one or more contingency maneuvers to change the flight (e.g., speed, position, direction, and/or altitude) of the aerial vehicle to avoid close calls or colliding with a potential conflict in the surrounding airspace. Such contingency maneuvers provide an automatic flight modification that may occur independently from any operator input.

  • Patent number: 10665115
    Abstract: A method, device, framework, and system provide the ability to control an unmanned aerial vehicle (UAV) to avoid obstacle collision. Range data of a real-world scene is acquired using range sensors (that provide depth data to visible objects). The range data is combined into an egospace representation (consisting of pixels in egospace). An apparent size of each of the visible objects is expanded based on a dimension of the UAV. An assigned destination in the real world scene based on world space is received and transformed into egospace coordinates in egospace. A trackable path from the UAV to the assigned destination through egospace that avoids collision with the visible objects (based on the expanded apparent sizes of each of the visible objects) is generated. Inputs that control the UAV to follow the trackable path are identified.
