Abstract
(EN)
Disclosed are a control method of unmanned aerial vehicles (1a, 1b, 1c) and unmanned aerial vehicles (1a, 1b, 1c). The control method of the unmanned aerial vehicles (1a, 1b, 1c) comprises: generating a course reversal command so that the unmanned aerial vehicles (1a, 1b, 1c) execute the course reversal action which at least includes a cruising stage; measuring the flight parameters of the unmanned aerial vehicles (1a, 1b, 1c) in the cruising stage; when determined to be in a high wind retardant state, the unmanned aerial vehicles (1a, 1b, 1c) enter a high wind course reversal stage; measuring the flight parameters in the high wind course reversal stage; when determined not to be in the high wind retardant state according to the flight parameters, the unmanned aerial vehicles (1a, 1b, 1c) return to the cruising stage.

L'invention concerne un procédé de commande de véhicules aériens sans pilote (1a, 1b, 1c) et des véhicules aériens sans pilote (1a, 1b, 1c). Le procédé de commande des véhicules aériens sans pilote (1a, 1b, 1c) comprend : la génération d'une instruction d'inversion de route de telle sorte que les véhicules aériens sans pilote (1a, 1b, 1c) exécutent l'action d'inversion de route qui comprend au moins une étape de croisière ; la mesure des paramètres de vol des véhicules aériens sans pilote (1a, 1b, 1c) dans l'étape de croisière ; lorsqu'il est déterminé qu'ils se trouvent dans un état de retard en cas de vents forts, les véhicules aériens sans pilote (1a, 1b, 1c) entrent dans une étape d'inversion de route pour vents forts ; la mesure des paramètres de vol dans l'étape d'inversion de route pour vents forts ; lorsqu'il est déterminé qu'ils ne se trouve pas dans l'état de retard en cas de vents forts en fonction des paramètres de vol, les véhicules aériens sans pilote (1a, 1b, 1c) retournent à l'étape de croisière.
