LANDING CONTROL METHOD AND DEVICE FOR UNMANNED AERIAL VEHICLE, AND UNMANNED AERIAL VEHICLE

WIPO Patent Application WO/2018/086030

A1

A landing control method and device for an unmanned aerial vehicle (2, 3, 4, 9), and unmanned aerial vehicle (2, 3, 4, 9). The method comprises: acquiring a desired landing speed of the unmanned aerial vehicle (2, 3, 4, 9) (201, 301, 501, 601, 801, 1003); and adjusting, according to the desired landing speed, a horizontal speed of the unmanned aerial vehicle (2, 3, 4, 9), such that the unmanned aerial vehicle (2, 3, 4, 9) lands according to the desired landing speed (202, 602, 802, 1004). By incorporating a horizontal motion while the unmanned aerial vehicle (2, 3, 4, 9) is moving downward, the prevent invention enables an airflow under a propeller (15, 16, 17, 18) of the unmanned aerial vehicle (2, 3, 4, 9) to have a horizontal component, such that if the unmanned aerial vehicle (2, 3, 4, 9) is to land at a high desired landing speed, a horizontal airflow can be effectively buffered, and an attitude of the unmanned aerial vehicle (2, 3, 4, 9) can remain stable without being influenced by turbulence.
