Abstract

La présente invention concerne un procédé de commande de fonctions dans un véhicule, en particulier un véhicule tracté, comportant au moins un capteur de vitesse de rotation de roue (15) et un ou plusieurs émetteurs de signaux et/ou récepteurs de signaux associés en particulier au côté arrière du véhicule. Selon l'invention, le capteur de vitesse de rotation de roue (15) détecte également le sens de rotation. En outre, les émetteurs de signaux et/ou récepteurs de signaux sont actionnés automatiquement en réponse à des signaux provenant du capteur de vitesse de rotation roue (15).
