Abstract

L'invention concerne un procédé de vérification d'une décision de déclenchement permettant de déclencher un dispositif de sécurité (410) pour un véhicule (400). Le procédé comprend une étape de lecture d'un signal de capteur (450) par au moins un élément d'acquisition (442) d'un dispositif de détection (440) du véhicule (400). Le signal de capteur (450) représente une grandeur de mesure physique à prendre en compte lors de la décision de déclenchement. Le procédé comprend en outre une étape de réalisation d'un contrôle du signal de capteur (450) pour rechercher la présence d'un événement de déclenchement, au moyen d'un circuit électronique (444) du dispositif de détection (440). Le circuit électronique (444) et l'élément d'acquisition (442) forment un module intégré. Le procédé comprend également une étape de détermination d'une information de vérification (455) au moyen d'un résultat du contrôle, destiné à être délivré à une interface de sortie (446) du dispositif de détection (440).
