Title
(EN) COLLISION DETECTION DEVICE
(FR) DISPOSITIF DE DETECTION DE COLLISION
Abstract
(EN)
A collision detection device disposed on a vehicle for properly actuating two or more occupant safety means (5, 6, 7, 8) that operate differently depending on forms of collisions such as front and side collisions, comprising two acceleration sensors (S1, S2) respectively provided in different directions and a controlling means (4) for selectively actuating the plurality of occupant safety means (5, 6, 7, 8) in accordance with directions of collisions on detecting the occurrence of a collision based on respective accelerations (Gx, Gy) detected by the acceleration sensors (S1, S2), wherein the controlling means (4) has collision detecting axes (A1-A5) that are set in advance in directions that are presumed as directions in which collisions are detected such as front, left, right and at least one direction that is different from the three directions and corresponds to the occupant safety means, calculates components (G1, G2, G3, G4, G5) of detected accelerations (Gx, Gy) corresponding to the respective collision detecting axes (A1-A5) and selects and operates occupant safety means (5, 6, 7, 8) that correspond to respective collision detecting axes (A1-A5) based on so calculated values (G1, G2, G3, G4, G5).
(FR)
Dispositif de détection de collision placé dans un véhicule et destiné à actionner au moins deux organes de sécurité (5, 6, 7, 8) pour les occupants fonctionnant différemment selon les formes de collisions, telles que les collisions frontales ou les collisions latérales. Ledit dispositif comprend deux détecteurs d'accélération (S1, S2) placés respectivement dans des directions différentes et un organe de commande (4) destiné à actionner sélectivement la pluralité de dispositifs de sécurité (5, 6, 7, 8) pour les occupants selon les directions de collision lorsque ledit dispositif détecte une collision sur la base d'accélérations respectives (Gx, Gy) détectées par les détecteurs d'accélération (S1, S2). L'organe de commande (4) possède des axes (A1-A5) de détection de collision fixés au préalable dans des directions qui sont présumées être des directions dans lesquelles les collisions sont détectées, telles que l'avant, la gauche, la droite et au moins une direction différente des trois directions susmentionnées et qui correspondent aux organes de sécurité pour les occupants. Ledit organe calcule des composantes (G1, G2, G3, G4, G5) des accélérations détectées (Gx, Gy) correspondant aux axes (A1-A5) de détection de collision respectifs et choisit et actionne des organes de sécurité (5, 6, 7, 8) qui correspondent aux axes respectifs de détection de collision sur la base des valeurs calculées (G1, G2, G3, G4, G5).
