ABSTRACT:
An activation device for a passenger protection apparatus comprises a sensor for detecting a roll angular velocity, a unit for calculating a roll relative angle on the basis of the angular velocity, and a unit for making a judgment indicating a roll of the vehicle when the velocity and the angle satisfy a threshold condition. A control unit activates an air bag and a pretentioner at a roll judgment. A buckle switch detects a wearing state of a seat belt, and a window opening/closure sensor detects an open/closed state of a window. The threshold condition is set on the basis of the results of the detection of the buckle switch and the window opening/closure sensor. This enables the protection apparatus to be appropriately activated on the basis of a wearing state of the seat belt and an open/closed state of the window of the vehicle.
