Abstract

La présente invention concerne un système de direction de conduite par fil pour diriger un véhicule automobile par un système de conduite par fil, où les signaux de direction sont entrés depuis un type de levier coulissant ou un dispositif d'entrée de type joystick qui soit une interface homme-machine dirigée par un conducteur dans un dispositif de commande de direction via les câbles de signal de direction par une opération de direction réalisée par le conducteur. Dans le dispositif de commande de direction, un dispositif de direction dirigeant un arbre de roue de direction est commandé pour la direction. Puisque le dispositif d'entrée du signal de direction et le dispositif de commande de la direction ou le dispositif de direction dirigeant l'arbre de roue de direction sont reliés l'un à l'autre via les câbles de signal de direction, les appareils pour les fonctions de direction peuvent être simplifiés et la position de direction sur le véhicule peut être définie de manière plutôt libre. Le dispositif d'entrée du signal de direction peut être fixé sur l'accoudoir d'un siège opérateur au lieu de le placer sur une roue de direction sur laquelle le dispositif d'entrée du signal de direction a été monté dans les véhicules automobiles conventionnels.
