Abstract
A system and method for controlling actuation of a vehicle passenger safety device in response to an event possibly requiring actuation of the safety device, wherein a modified differentiated measure is generated from received vehicle acceleration information by subtracting the absolute value of a prior-in-time value therefor from its current value, whereby the distortion introduced by negative prior-in-time values is significantly reduced. The resulting modified jerk measure is more useful in discriminating crash events than is a nominal jerk measure, given the latter's predisposition to fail as a useful measure upon encountering negative prior-in-time values.
