ABSTRACT:
An activation device for a passenger protection apparatus is made up of a sensor for detecting a roll angular velocity of a vehicle, a unit for calculating a roll relative angle on the basis of the roll 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 when making a judgment indicating a roll. A vehicle collision state is discriminated on the basis of right-hand and left-hand accelerations detected by acceleration sensors and the threshold condition for the judgment on a roll of the vehicle is switched in accordance with the collision state. This enables a trip-over type roll to be detected at an early stage for activating the passenger protection apparatus quickly.
