  • Vehicle rollover detection apparatus and method
    Patent number: 6542792
    Abstract: A vehicle rollover sensing apparatus and method are provided for detecting an overturn condition of the vehicle. The rollover sensing apparatus includes an angular rate sensor for sensing attitude rate of change of a vehicle and producing an output signal indicative thereof. The rollover sensing apparatus also has an integrator for integrating the sensed attitude rate of change signal over a variable time window and producing an attitude angle. The rollover sensing apparatus further includes deployment logic for comparing the attitude angle and attitude rate of change to a pair of variable threshold values, with a gray-zone that varies based on time, and an output for deploying a vehicle overturn condition signal based on the comparison. Adaptive bias removal and output minimum logic reduces bias and noise associated with the sensed signal.
