Abstract

L'invention concerne un appareil de calcul de plage, caractérisé par le fait qu'il comprend : un premier moyen d'acquisition (170) qui acquiert des informations de véhicule incluant la position actuelle d'un véhicule et le niveau d'énergie restante actuel du véhicule ; un second moyen d'acquisition (170) qui acquiert, en tant que première distance, la distance de la position actuelle à un point prédéfini ; un moyen d'estimation (170) qui estime un niveau d'énergie restante lorsque le véhicule arrivera au point prédéfini ; et un moyen de calcul (170) qui réalise un premier traitement de calcul dans lequel une seconde distance est calculée en multipliant le niveau d'énergie restante estimé par le moyen d'estimation (170) par un rendement d'énergie prédéfini, et la somme de la première distance et de la seconde distance est calculée en tant que plage du véhicule.
