Abstract
An airbag deployment control apparatus includes a 3-direction accelerometer and a crash-pattern discriminating portion in order to reliably distinguish a slight crash from a serious crash or vice versa. The 3-direction accelerometer generates deceleration signals of traveling, right-left and upper-lower directions of a vehicle. The deceleration signals generated are inputted to an integrator to be converted into 3-direction velocity change signals. In the crash-pattern discriminating portion, crash patterns are discriminated by use of the 3-direction velocity change signals. In an airbag-deployment determining portion, the velocity change is compared with a threshold for a crash pattern discriminated and an airbag deploying signal is outputted to an airbag deploying portion when the velocity change exceeds the threshold. The threshold is predetermined classified by crash patterns. In practice, since the delay deployment of the airbag is prevented, it is possible to protect passengers reliably.
