Abstract

Système et méthode utilisés pour déclencher le déploiement des coussins gonflables d'un véhicule à la suite d'une collision ou d'une décélération soudaine du véhicule au moyen desquels une valeur modifiée de l'accélération est obtenue en soustrayant un facteur de correction des données représentatives de l'accélération instantanée du véhicule qui a été détectée; en intégrant la valeur modifiée de l'accélération pour arriver à une valeur modifiée de la vitesse; en estimant la variation transitoire des données relatives à l'accélération grâce à un filtre de rang; en obtenant le produit de la variation transitoire estimée et de la vitesse modifiée; en comparant le produit de la vitesse par la variation transitoire à une valeur seuil, et en déclenchant le déploiement du coussin d'air gonflable lorsque le produit de la vitesse par la variation transitoire dépasse la valeur seuil prévue.
