Dans des opérations à distance du véhicule de travail, c'est-à-dire une machine de construction ou analogue, des informations de vibrations de carrosserie de véhicule deviennent perceptibles par un opérateur dans un emplacement à distance. La présente invention aborde le problème de réduction de la probabilité pour l'opérateur de souffrir d'un mal des transports par la transmission des informations de vibrations de carrosserie de véhicule dont les fréquences provoquant le mal des transports ont été éliminées, lorsque les informations de vibrations de carrosserie de véhicule deviennent perceptibles par l'opérateur. En conséquence, la présente invention est caractérisée en ce qu'elle est configurée à partir de ce qui suit : des capteurs pour détecter une machine de construction et des informations de vibrations de machine de construction ; un dispositif d'élimination de bande permettant d'éliminer les fréquences provoquant le mal des transports à partir des informations de vibrations détectées ; une caméra pour visualiser l'état de la périphérie de la machine de construction ; un poste de pilotage à distance dans lequel s'assoit un opérateur ; et un actionneur pour entraîner le poste de pilotage à distance. La présente invention est en outre caractérisée en ce que l'actionneur pour entraîner le poste de pilotage à distance est entraîné à l'aide des informations de vibrations dont les fréquences provoquant le mal des transports ont été éliminées, pour reproduire les informations de vibrations de la machine de construction.
