Title
(EN) MATCHED FILTER FOR VEHICLE CRASH DISCRIMINATION
(FR) FILTRE ADAPTE DECISIONNEL POUR COLLISIONS DE VEHICULES
Abstract
(EN)
A matched filter (14) for vehicle crash discrimination system (10) utilizes at least one set of n scaling factors stored in a memory (24) to combine (22a-n) with a set of n time sequenced acceleration data samples. The values of the n scaling factors are selected to effect a desired vehicle crash discrimination strategy. The scaled, or filtered samples, are then summed (26) to generate an output signal suitable for use in a crash discrimination analysis. The matched filter (14) optimizes system design flexibility and reconfigurability by allowing different strategies to be implemented simply by selecting the appropriate scaling factors stored in the memory.

Filtre adapté (14) d'un système décisionnel (10) pour collisions de véhicules (10) utilisant au moins un groupe de n facteurs d'échelle stockés dans une mémoire (24) et destinés à se combiner (22a-n) avec un groupe de n échantillons de données d'accélération à séquence temporelle. Les valeurs des n facteurs d'échelle sont sélectionnées pour produire une stratégie décisionnelle de collision requise. Les échantillons mis à l'échelle ou filtrés sont ensuite sommés (26) pour produire un signal de sortie utilisable dans l'analyse décisionnelle. Le filtre adapté (14) permet d'optimiser la souplesse de conception et l'aptitude à la reconfiguration en permettant de mettre en oeuvre différentes stratégies simplement en par sélection des facteurs d'échelle appropriés se trouvant en mémoire.
