Abstract

L'invention concerne un dispositif indicateur pour un véhicule équipé d'une unité d'indication de couple (100) qui indique de manière graphique une quantité du couple généré dans les roues motrices du véhicule. L'unité d'indication de couple est équipée de groupes de segments indicateurs (2A, 2B) qui sont agencés au-dessus et en dessous d'une partie de référence prédéterminée, et seul un segment indicateur disposé au niveau d'une position sélectionnée sous le contrôle d'une unité de commande d'indicateur (5) est allumé. Quand la quantité du couple généré dans les roues motrices est positive, l'unité de commande d'indicateur (5) sélectionne et allume un segment indicateur (3a-3f) qui correspond à la quantité de couple en provenance du groupe de segments indicateurs se trouvant au-dessus de la partie de référence prédéterminée (101). Quand la quantité du couple généré dans les roues motrices est négative, l'unité de commande d'indicateur (5) sélectionne et allume un segment indicateur (4a-4f) qui correspond à la quantité de couple en provenance du groupe de segments indicateurs se trouvant en dessous de la partie de référence prédéterminée.
