Abstract

Procédé d’évaluation d’une loi de décélération et procédé d’assistance à la conduite L’invention porte sur un procédé d’évaluation de la loi de décélération d’un véhicule comprenant une pédale d’accélérateur, une pédale de frein, une chaine de traction comprenant un moteur, une boite de vitesses et un organe de coupure entre le moteur et la boite de vitesses, la loi de décélération étant définie pour un état discret de la chaine de traction, le procédé d’évaluation de la loi de décélération comprenant : - une première étape (100) d’évaluation de paramètres de conduite comprenant la mesure de la vitesse (v) du véhicule, l’évaluation du rapport de la boite de vitesses engagé, l’évaluation de l’état de fermeture de l’organe de coupure, la détection de la position de la pédale d’accélérateur, la détection de la position de la pédale de frein, l’évaluation de la pente (a) de la route sur laquelle roule le véhicule, l’évaluation de la masse (m) du véhicule, - si la pédale d’accélérateur est dans une position relâchée et si la pédale de frein est dans une position relâchée, une deuxième étape (200) comprenant l’enregistrement de la vitesse (v) du véhicule et de la pente (a) de la route, - une troisième étape (300) de calcul d’un premier coefficient (f0’), d’un deuxième coefficient (f1’) et d’un troisième coefficient (f2’) de la loi de décélération représentant les forces F(v) s’appliquant au véhicule à l’exception des efforts gravitationnels appliqués au véhicule selon l’équation : F(v)=f0’ + f1’ * v + f2’ * v². L’invention porte également sur un procédé d’assistance à la conduite économe en énergie utilisant la loi de décélération évaluée grâce au procédé précédent. Figure pour l’abrégé : Figure 1
