Abstract

L'invention concerne un système (5) destiné à un véhicule à moteur (300), lequel système comprend un levier ou une pédale actionnés au pied ou à la main (40,150) et destinés à réguler manuellement la puissance développée par un moteur /ou le moteur de propulsion du véhicule (300). Le système (5) comprend un agencement (20,40) destiné à indiquer en fonctionnement à un conducteur du véhicule (300) les valeurs présentes de limitation de vitesse (VO) sur l'itinéraire emprunté par le véhicule (300). Le système (5) est conçu pour recevoir des informations concernant les limitations de vitesse applicables (V3) entrées manuellement par le conducteur pour modifier le fonctionnement du système (5) en respectant ces limitations de vitesse (VO). Le système (5) peut améliorer la sécurité routière en encourageant les conducteurs à se conformer sensiblement aux limitations de vitesse prescrites dans les zones de trafic.
