Title:
LANDING GEAR CONTROL METHOD AND DEVICE FOR UNMANNED AERIAL VEHICLE, UNMANNED AERIAL VEHICLE, AND SYSTEM FOR SAME
Document Type and Number:
WIPO Patent Application WO/2018/133006
Kind Code:
A1
Abstract:
A landing gear control method and device for an unmanned aerial vehicle, user equipment unit, unmanned aerial vehicle, and unmanned aerial vehicle system. The method comprises: detecting whether a ground height of an unmanned aerial vehicle is greater than a first predetermined height threshold, the ground height being a vertical height of the unmanned aerial vehicle with respect to an object; if the ground height is not greater than the first predetermined height threshold, and the unmanned aerial vehicle has not lowered landing gear, then adjusting the ground height to the first predetermined height threshold or above, and lowering the landing gear. The above method is used to prevent automatic lowering of landing gear when an unmanned aerial vehicle is likely to touch the ground, thus effectively preventing serious consequences such as a crash caused by hard landing, improving safety of the unmanned aerial vehicle during flight and landing, and protecting a fuselage of the unmanned aerial vehicle from damage to the greatest extent.
