Abstract

La présente invention concerne le domaine des automobiles; l'invention concerne un procédé de réglage de la vitesse d'un véhicule en fonction d'une limite de vitesse de route, et un système de limitation de vitesse, ledit procédé comprenant les étapes consistant à : enregistrer une limite de vitesse correspondant à une route de véhicule; détecter le déplacement d'un véhicule actuel sur la route; faire correspondre une limite de vitesse en fonction du véhicule circulant actuellement sur la route, et régler le réglage de la vitesse du véhicule en fonction de la limite de vitesse correspondant à la route actuellement parcourue. Dans la présente invention, une limite de vitesse correspondant à une route parcourue par un véhicule est prédéfinie; pendant que le véhicule se déplace sur la route, la vitesse du véhicule est réglée en fonction de la limite de vitesse de route, ce qui permet au conducteur d'ajuster la vitesse du véhicule, évitant ainsi les accélérations et améliorant la sécurité du trafic.
