Abstract

La présente invention concerne de manière générale un véhicule à deux roues (1). Plus particulièrement, mais pas exclusivement, la présente invention concerne un groupe d'instruments (200) destiné audit véhicule à deux roues (1). Le groupe d'instruments (200) comprend un écran numérique (202) qui est une combinaison d'une unité d'affichage statique (402a, 402b, 402c) et d'une unité d'affichage dynamique (306, 307, 401). L'unité d'affichage statique (402a, 402b, 402c) est un dispositif d'affichage à segments et l'unité d'affichage dynamique (401) est un dispositif d'affichage à matrice par points. Le schéma de puissances (307) montre la contribution de puissance entre la batterie et le moteur et une unité d'affichage d'application (401) affiche la pluralité sélectionnée de menus à partir de l'application personnalisée mémorisée dans un dispositif intelligent.
