Title
(EN) METHOD AND SYSTEM FOR CONTROLLING A VEHICLE CRUISE CONTROL
(FR) PROCÉDÉ ET SYSTÈME POUR COMMANDER UNE COMMANDE DE VITESSE DE CROISIÈRE DE VÉHICULE
Abstract
(EN)
A method and a vehicle cruise control system performing the steps of: -driving with said cruise control active and set to maintain a set target speed (vcc set target speed); -registering a first position (A) when driving in an uphill slope of a hill where vehicle retardation has decreased vehicle speed to a first speed (vmin) below said set target speed and where said retardation has decreased to zero or acceleration has just started in order to increase speed to said set target speed; -registering a desired speed (vbcc overspeed) in a second position (C1, C2) downhill of said crest at a first distance (y1, y2 ) after said crest; -based on said desired speed calculating a minimum speed (vmin1, vmin2,vmin3) at said crest with which said vehicle has to pass said crest in order to be able to reach said desired speed with zero fuel consumption during said first distance (y1, y2 ); -controlling speed between said first position (A) and said crest (B) so that said vehicle reaches said minimum speed (vmin1,vmin2,vmin3) when passing said crest.
(FR)
L'invention porte sur un procédé et sur un système de commande de vitesse de croisière de véhicule qui réalise les étapes consistant à : entraîner avec ladite commande de vitesse de croisière active et établie pour maintenir une vitesse cible établie (vcc vitesse cible établie) ; enregistrer une première position (A) lors de l'entraînement dans une pente montante d'une colline dans laquelle un retard de véhicule a diminué une vitesse de véhicule à une première vitesse (Vmin) en dessous de ladite vitesse cible établie et dans laquelle ledit retard a diminué à zéro ou une accélération a juste démarré afin d'augmenter une vitesse vers ladite vitesse cible établie ; enregistrer une vitesse souhaitée (vbcc dépassement de vitesse) dans une seconde position (C1, C2) en bas de la pente dudit sommet à une première distance (y1, y2) après ledit sommet ; en fonction de ladite vitesse souhaitée, calculer une vitesse minimale (vmin1, vmin2, vmin3) audit sommet à laquelle ledit véhicule doit passer ledit sommet afin d'être apte à atteindre ladite vitesse souhaitée avec une consommation de carburant nulle lors de ladite première distance (y1, y2) ; commander une vitesse entre ladite première position (A) et ledit sommet (B) de telle sorte que ledit véhicule atteint ladite vitesse minimale (vmin1, vmin2, vmin3) lors du passage dudit sommet.
