A dual control device for actuating the pedals (16, 17, 18) of a vehicle (6). The device comprises three mechanical sensors (2, 3, 4) generating signals representing the actions of a user's feet, an electrical control circuit (37) receiving said signals and using them to control the rotation of three winch drives (22, 23, 24) connected to the respective mechanical pull wires of the pedals (16, 17, 18) so that they can selectively draw said pedals closer to the floor (19) of the vehicle. Each drive is preferably combined with a position sensor (34, 35, 36) having a variable electrical response depending on the position of said drives. Furthermore, the electrical circuit (37) is connected to said position sensors to provide automatic control of the position of the mechanical pull wires (101, 111, 121) slidably mounted in sleeves and connected to the pedals (16, 17, 18), depending on the electrical responses of the position sensors.

La présente invention concerne un dispositif de double commande agissant sur les pédales (16, 17, 18) du véhicule (6). Ce dispositif comporte trois capteurs mécaniques (2, 3, 4) fournissant des signaux représentatifs d'actions de pieds d'un utilisateur, un circuit électrique de commande (37) recevant lesdits signaux et commandant en fonction de ces signaux, les rotations de trois organes moteurs (22, 23, 24) avec treuil reliés respectivement aux câbles mácaniques de traction des pédales (16, 17, 18) pour tirer à la demande ces dernières vers le plancher (19) du véhicule. Préférentiellement, est associé à chaque organe moteur, un capteur de position (34, 35, 36) apte à posséder une réponse électrique variable en fonction de la position desdits moteurs. Par ailleurs le circuit électrique (37) est relié à ces capteurs de position et assure un asservissement de la position des câbles mécaniques (101, 111, 121) montés en coulissement dans des gaines et reliés aux pédales (16, 17, 18) en fonction des réponses électriques des capteurs de position.
