Abstract: A rollover sensing apparatus and method are provided for predicting rollover and/or pitchover conditions of a vehicle. An angular rate sensor senses attitude rate of the vehicle, a first accelerometer measures horizontal acceleration of the vehicle, and a second accelerometer measures vertical acceleration of the vehicle. A current attitude angle is estimated with Kalman filtering and a future attitude angle is predicted at an advance time. The predicted attitude angle is compared to a threshold and an output is produced for indicating a predicted vehicle rollover condition based on the comparison. A vehicle rollover condition about the longitudinal axis of the vehicle is predicted by comparing a future roll angle to a rollover angle threshold, while a pitchover condition about the lateral axis of a vehicle is predicted by comparing a future pitch angle to a pitch angle threshold.

Abstract: A rollover sensing apparatus and method are provided for predicting rollover or pitchover conditions of a vehicle. The apparatus and method sense angular roll rate, angular pitch rate, longitudinal acceleration, lateral acceleration, and vertical acceleration of the vehicle and produce output signals indicative thereof. A non-linear filter, such as an extended Kalman filter, estimates a current roll angle and a current pitch angle as a function of the sensed signals. A predictor predicts a future roll angle as a function of the estimated current roll angle and the sensed roll rate, and further predicts a future pitch angle as a function of the estimated current pitch angle and the sensed pitch rate. The predicted roll and pitch attitude angles are compared to a threshold value and a vehicle overturn condition signal is output to indicate a predicted vehicle rollover or pitchover condition.
