Abstract

A control device actuates at least one vehicular safety device such as a seat belt pretensioning mechanism, an airbag, an automatic roll-over bar, a door lock or a cellular phone comprising a sensor stage to sense a plurality of parameters including acceleration, pitch angle and roll angle of a vehicle. A corresponding plurality of digital signals representing each such parameter are generated. A control stage includes circuitry to receive the plurality of digital signals and to generate a control signal corresponding to each such parameter when the corresponding digital signal exceeds a predetermined value. A safety device actuator includes circuitry to receive the control signals and to generate a corresponding actuator signal to actuate the corresponding vehicular safety device.
