Title
(EN) METHOD FOR DAMPING CRASH-DISCRIMINATION MEASURES
(FR) PROCEDE D'ATTENUATION DE MESURES D'EVALUATION DE L'IMPORTANCE DES COLLISIONS
Abstract
(EN)
In a system and method (20) for controlling actuation of a vehicle passenger safety device, wherein a first time-varying measure $i(m)1($i(t)), itself a function of received vehicle acceleration information, is accumulated to obtain a second time-varying measure $i(m)2($i(t)) for subsequent comparison with a threshold value therefor, the first measure $i(m)1($i(t)) is 'damped' (20) prior to accumulation (29) by subtracting therefrom a correction value or 'damping factor $i(f)d'. In accordance with one aspect of the invention, the damping factor $i(f)d comprises a time-varying function $i(f)d($i(t)) of one or more other time-varying measures, themselves based on received vehicle acceleration information.
(FR)
Dans un système (20), et dans le procédé associé, commandant le déclenchement d'un dispositif de sécurité d'un véhicule de transport de passagers, dans lequel une première mesure fonction du temps $i(m)1($i(t)), elle-même fonction d'informations reçues relatives à l'accélération du véhicule, est accumulée pour fournir une deuxième mesure fonction du temps $i(m)2($i(t)), en vue d'une comparaison ultérieure avec une valeur seuil, on 'atténue' (20) à cet effet la première mesure $i(m)1($i(t)) avant l'accumulation (29) en lui soustrayant une valeur corrective ou 'facteur d'atténuation' $i(f)d. Selon l'un des aspects de l'invention, le facteur d'atténuation $i(f)d comporte une fonction de temps $i(f)d($i(t)) d'une ou plusieurs autres fonctions de temps, elles-mêmes basées sur les informations reçues relatives à l'accélération du véhicule.
