Abstract

L'invention concerne un procédé et un agencement d'émission d'un appel d'urgence en fonction d'un critère d'accident prédéterminé. L'appel d'urgence comprend un ensemble de données avec des données générales et des données spécifiques à l'accident qui ont été déterminées à partir des données dynamiques de capteurs d'un système de protection des passagers et/ou des piétons (1) qui ont été enregistrées avant et/ou après l'occurrence d'un critère d'accident et qui autorisent des conclusions sur la situation de l'accident. Selon l'invention, au cours d'une première période de temps, à partir d'un premier instant avant l'occurrence du critère d'accident proprement dit, l'ensemble de données est préparé pour un appel d'urgence potentiel et est placé dans un format d'émission prédéterminé. Le premier instant est déterminé lorsqu'est détectée une situation de danger potentielle conduisant à un critère d'accident.
