Abstract

Selon un exemple de mode de réalisation de l'invention, un avertissement de danger est donné au conducteur d'un véhicule, des valeurs de mesure détectées par différents véhicules ou des résultats d'analyse préalable correspondants étant évalué(e)s de manière centralisée par un serveur. Le serveur décide alors de qui doit recevoir un avertissement correspondant. De cette manière, l'opération de calcul principale peut s'effectuer dans le serveur, ce qui permet de décharger les systèmes individuels des véhicules. L'invention permet également de minimiser le transfert de données, les messages n'étant envoyés qu'à des destinataires sélectionnés.
