Abstract

L'invention concerne un procédé, un dispositif et un système, un véhicule aérien, un porteur (120), et un dispositif de commande. Le procédé de commande consiste : à déterminer un mode de vol d'un véhicule aérien (210) ; s'il est déterminé que le mode de vol est un mode de vol en posture droite, à adopter un premier mode de contrôle en position droite pour contrôler un mouvement d'un porteur du véhicule aérien (220) ; et s'il est déterminé que le mode de vol est un mode de vol inversé, à adopter un premier mode de contrôle inversé pour contrôler le mouvement du porteur, selon la même instruction de contrôle, une manière selon laquelle un état de mouvement du porteur change dans le premier mode de contrôle en position droite étant différente d'une manière selon laquelle l'état de mouvement du porteur change dans le premier mode de contrôle inversé, de sorte que lorsque le mode de vol du véhicule aérien change, il n'est pas nécessaire qu'un utilisateur change son mode de contrôle habituel par rapport au porteur du véhicule aérien, améliorant ainsi le confort de l'utilisateur.
