Abstract

The collision detection device for appropriately actuating two or more types of passenger safety devices (5,6,7,8) which are installed on a vehicle and respectively have different performances depending on collision types such as a front collision and a side collision, and comprising two acceleration sensors (S1,S2) installed respectively in different directions and a controller for selecting appropriate passenger safety devices to be actuated from said plurality of passenger safety devices in accordance with a direction of a collision when recognizing the collision on the basis of accelerations detected by the two acceleration sensors, and for actuating them, said controller (4) having collision detecting axes related with said passenger safety devices respectively, said collision detecting axes preset in directions assumed as directions for detecting the collision which are front, right and left directions and further at least one additional directions which are different from said front, right and left directions, said controller (4) which arithmetically obtains components (G1,G2,G3,G4,G5) of an acceleration concerning the collision along said collision detecting axes on the bas…
