  • Patent number: 11427316
    Abstract: A bionic visual navigation control system for autonomous aerial refueling docking includes: a tanker/receiver bottom layer control module, a multi-wind disturbances hose-drogue stable control module, an enable and select module, a close-range bionic vision relative navigation module, and a receiver relative position precise control module. A bionic visual navigation control method for autonomous aerial refueling docking is also provided. The present invention aims at improving the reliability, anti-interference and accuracy of the close-range relative navigation in the autonomous air refueling docking stage, and designs a matching relative position accurate control method with control switch, thereby improving the accuracy of close-range navigation and control, thereby promoting the successful realization of probe-and-drogue autonomous aerial refueling and improving the autonomy of UAVs.

  • Publication number: 20200339159
    Abstract: An automatic driving track obtaining method and apparatus are provided. The method includes: obtaining a driving style coefficient of a driver of a vehicle A (S101); calculating a cost function of the driver of the vehicle A based on the driving style coefficient of the driver of the vehicle A (S102), where the cost function is used to represent costs paid when the vehicle A travels from an initial node to a current node in a driving track of the vehicle A; and obtaining the driving track of the vehicle A on a first three-dimensional spatial-temporal map through calculation according to the cost function (S103). The driving track obtained by using the method and the apparatus can match driving styles of all drivers. This improves driver satisfaction on the driving track, and lessens a running-in period in which the driver performs automatic driving.

  • Publication number: 20190033893
    Abstract: A UAV autonomous swarm formation rotation control method based on a simulated migratory bird evolutionary snowdrift game includes steps of: Step 1: initializing; Step 2: determining flight mode based on a migratory bird evolutionary snowdrift game; Step 3: determining the leader and its position relative to corresponding wing UAV; Step 4: running UAV model; and Step 5: determining whether to end simulation. The present invention is to provide a distributed UAV autonomous swarm formation rotation control method, so as to improve robustness and adaptability of the UAV in autonomous swarm formation rotation, thus effectively improving long-range mission execution capability of the UAV.
