Apparatus and method for controlling activation of vehicle occupant protecting device

摘要

An apparatus for controlling an output of an air bag device (30) such that the output is made relatively high when a deceleration value (GF) detected by a floor sensor (14) disposed in a central portion of a vehicle body is higher than a threshold which changes with a velocity (∫GF.dt) which is obtained as a time integral of the deceleration value (GF). The threshold is changed from a normally selected high value to a low value when one of two deceleration values (GSL, GSR) detected by respective two satellite sensors (16, 18) disposed in front left and right portions of the vehicle body has reached a threshold value which changes with the velocity (∫GF.dt).
