Abstract

Cette invention a pour objet un procédé destiné à fournir à un observateur des informations concernant un véhicule d'intervention se trouvant en intervention, un signal d'intervention acoustique du véhicule d'intervention étant détecté comme étant multicanal. A partir d'une évaluation du signal d'intervention acoustique détecté, on obtient des informations concernant une direction de mouvement du véhicule d'intervention par rapport à l'observateur. En fonction de ces informations, un signal d'avertissement acoustique est émis par le biais d'une installation de signalisation audio actionnée par l'observateur, l'installation de signalisation audio disposant d'une pluralité de haut-parleurs permettant de produire une impression de stéréophonie. Pour produire le signal d'avertissement, ces haut-parleurs sont dirigés de telle sorte que l'observateur ait l'impression que le signal d'avertissement provient de la direction du véhicule d'intervention se rapprochant. Cette invention concerne également le dispositif correspondant au procédé décrit. L'invention présente l'avantage que l'observateur, en particulier un conducteur de véhicule, est mieux informé de l'approche d'un véhicule d'intervention qui se trouve en intervention. En particulier, les informations concernant le mouvement du véhicule d'intervention peuvent être détectées de manière plus intuitive que dans le cas d'un affichage optique. En outre, l'attention du conducteur du véhicule sur la circulation environnante est moins diminuée.
