Abstract

L'invention concerne un appareil de commande pour un véhicule électrique, comprenant un moyen d'entrée conçu pour générer un signal indiquant un mouvement vers l'avant voulu du véhicule, et un signal indiquant un mouvement de giration voulu du véhicule; un appareil d'entraînement conçu pour entraîner une roue gauche et une roue droite du véhicule, et pour entraîner les roues droite et gauche selon différentes vitesses angulaires, en réponse au signal de mouvement de giration voulu, de sorte qu'un mouvement de giration soit induit. Ledit appareil d'entraînement est, de plus, conçu pour permettre la détermination de la différence entre les vitesses angulaires respectives, en fonction du signal de déplacement vers l'avant. Un autre appareil de commande est décrit. Celui-ci comprend des moyens pour générer un signal indiquant une composante vers l'avant de la vitesse du véhicule, et son appareil d'entraînement est conçu pour déterminer la différence entre les différentes vitesses angulaires respectives, en fonction de la composante vers l'avant du signal de vélocité. Des organes de commande pour un véhicule électrique et les méthodes de guidage correspondantes d'un véhicule électrique sont également décrits.
