Abstract

Un procédé est implémenté dans un véhicule stockant des lois de route associées à des masses prédéfinies et fonction de la vitesse en cours, et fournissant une puissance effective. Ce procédé comprend une étape (10-50) dans laquelle, lorsque le véhicule a une vitesse constante, on estime une puissance effective avec l’une des lois de route pour cette vitesse, puis on détermine une différence entre les puissances effectives estimée et fournie, et lorsque cette différence est inférieure à un seuil on choisit la masse prédéfinie associée à cette loi de route comme masse en cours, sinon on effectue au moins une autre estimation de puissance effective avec une autre loi de route pour cette vitesse et une autre détermination de différence jusqu’à obtention d’une différence inférieure au seuil et choix de la masse prédéfinie associée à la loi de route correspondante comme masse en cours. Figure 3A method is implemented in a vehicle storing road laws associated with predefined masses and depending on the current speed, and providing an effective power. This method comprises a step (10-50) in which, when the vehicle has a constant speed, an effective power is estimated with one of the road laws for this speed, then a difference is determined between the estimated and provided effective powers, and when this difference is less than a threshold, the predefined mass associated with this road law is chosen as the current mass, otherwise at least one other estimate of effective power is carried out with another road law for this speed and another difference determination until a difference less than the threshold is obtained and the predefined mass associated with the corresponding road law is chosen as the current mass.
