Abstract

L'objet de l'invention est une configuration liée à la situation, de bruits artificiels de véhicule et de moteur, en particulier pour des véhicules électriques. A cet effet, un détecteur de situation reçoit de nombreuses données de mesure de plusieurs capteurs, pondère ces dernières et les utilise pour évaluer la situation. Le détecteur de situation calcule à partir de cela des signaux de commande pour un système de haut-parleur à la fois à l'extérieur du véhicule et à l'intérieur du véhicule, lesquels peuvent tous les deux émettre des bruits artificiels de véhicule et de moteur. Cela permet ainsi d'accroître la sécurité routière.
