Abstract

La présente invention concerne un dispositif de navigation (1) qui, lorsqu'une irrégularité de rendement du carburant (μ+σ) associée à un segment routier sur lequel le véhicule concerné (C) circule est supérieure à un seuil défini (μ×α), affiche des informations d'assistance à la conduite qui sont des informations associées à une conduite économique (étapes S204 et S206 sur la figure 8). Grâce à ce type de configuration, il est possible de supprimer l'inconfort lié aux informations d'assistance à la conduite et d'augmenter la confiance par affichage des informations d'assistance à la conduite associées à des segments routiers pour lesquels l'irrégularité du taux de rendement énergétique (μ+σ) est supérieure au seuil défini (μ×α) ou, en d'autres termes, à des segments routiers pour lesquels la marge de manœuvre permettant d'augmenter le taux de rendement énergétique est plus grande.
