Abstract:
A method of triggering a gas generator for an air bag for use in a motor vehicle, having acceleration sensors, an air bag, a gas generator which supplies a filling medium for filling the air bag, and an air bag control unit which evaluates a collision by evaluating signals of the acceleration sensors and which, by way of a control signal, triggers the gas generator, a volume flow of the filling medium supplied by the gas generator during a filling operation being influenceable by the control signal, comprising:changing the control signal, as a function of evaluation of the collision, to adjust the gas generator triggering frequency and adapt filling of the air bag to collision seriousness, wherein evaluation of a collision for triggering the gas generator takes place based on a determined average acceleration, wherein a signal for the average acceleration is generated which unambiguously assigns a voltage to an acceleration, and wherein the control signal is generated by way of a voltage/frequency converter from the signal for the average acceleration.
