Abstract

Un dispositif de commande d'affichage (19) commande l'affichage d'un affichage tête haute (17) disposé dans un véhicule. Le dispositif de commande d'affichage est pourvu d'une unité de détermination d'état spécifique et d'une unité d'affichage attirant l'attention. L'unité de détermination d'état spécifique détermine si le véhicule est dans un état spécifique, à savoir que le véhicule est positionné devant une lumière rouge et que la vitesse du véhicule est au plus égale à un seuil prédéterminé. Si l'unité de détermination d'état spécifique détermine que le véhicule est dans l'état spécifique, l'unité d'affichage attirant l'attention utilise l'affichage tête haute pour effectuer un affichage attirant l'attention afin d'encourager le conducteur du véhicule à attirer son attention vers l'avant du véhicule.
