CA 2687522

The invention relates to a driving assistance device (100) for a vehicle for travelling along a predetermined path between a first point and a second point. The invention is characterised in that the assistance device includes a generation means for generating a curve of optimal driving parameters for optimising the energy burnt by the vehicle for travelling along said path and the time required for travelling along said path, a means (180) for determining a current driving profile of the vehicle, a means (220) for determining an optimal driving profile for the current position from the optimal profile curve, a comparator (300) for determining a deviation between the current driving profile and the optimal driving profile for the current position, and a means (320) for correcting the driving profile of the vehicle based on the determined deviation (.epsilon.(t)).

L'invention concerne un dispositif d'assistance à la conduite (100) pour un véhicule destiné à parcourir un trajet défini entre un premier point et un deuxième point. L'invention se caractérise par le fait que le dispositif d'assistance comporte des moyens de génération pour générer une courbe de profils de conduite optimaux visant à optimiser l'énergie consommée par le véhicule pour parcourir le trajet et le temps mis pour parcourir le trajet, des moyens (180) pour déterminer un profil de conduite courant à une position courante du véhicule, des moyens (220) pour déterminer un profil de conduite optimal pour la position courante à partir de la courbe de profils optimaux, un comparateur (300) pour déterminer un écart entre le profil de conduite courant et le profil de conduite optimal pour la position courante, des moyens (320) pour corriger le profil de conduite du véhicule en fonction de l'écart déterminé (.epsilon.(t)).
