Abstract: A vehicle rollover sensing apparatus (10) and method are provided for detecting an overturn condition of the vehicle. The rollover sensing apparatus (10) includes an angular rate sensor (12) for sensing attitude rate of change of a vehicle and producing an output signal indicative thereof. The rollover sensing apparatus also has an integrator (64) for integrating the sensed attitude rate of change signal over a variable time window (80) and producing an attitude angle. The rollover sensing apparatus further includes deployment logic (66) for comparing the attitude angle and attitude rate of change to a pair of variable threshold values, with a gray-zone (150) that varies based on time, and an output (56) for deploying a vehicle overturn condition signal based on the comparison. Adaptive bias removal and output minimum logic (62) reduces bias and noise associated with the sensed signal.

Abstract: The absolute roll angle of a vehicle body (16) is estimated by blending two preliminary roll angle estimates based on their frequency (48) so that the blended estimate continuously favors the more accurate of the preliminary roll angle estimates. A first preliminary roll angle estimate based on the measured roll rate (22) is improved by initially compensating the roll rate signal for bias error using roll rate estimates inferred from other measured parameters (44). And a second preliminary roll angle estimate is determined based on the kinematic relationship among roll angle, lateral acceleration, yaw rate and vehicle speed (46). The blended estimate of roll angle utilizes a blending coefficient that varies with the frequency of the preliminary roll angle signals, and a blending factor used in the blending coefficient is set to different values depending whether the vehicle (10) is in a steady-state or transient condition (48).
