Abstract: A vehicle rollover detection apparatus and method are provided for detecting an overturn condition of the vehicle. The rollover detection apparatus includes an angular rate sensor sensing angular rate of the vehicle, and a vertical accelerometer for sensing vertical acceleration of the vehicle. A controller processes the sensed angular rate signal and integrates it to produce an attitude angle. The vertical acceleration signal is processed to determine an inclination angle of the vehicle. The rollover detection apparatus adjusts the attitude angle as a function of the inclination angle and compares the adjusted attitude angle and the processed angular rate signal to a threshold level to provide a vehicle overturn condition output signal. Additionally, the rollover detection apparatus detects a near-rollover event and adjusts the variable threshold in response thereto to prevent deployment of a vehicle overturn condition, thus providing immunity to such events.

Abstract: A vehicle seat occupant classification system uses a pressure responsive, fluid filled bladder and pressure sensor adapted for engagement with an underside of a foam seat cushion so as to generate a pressure signal corresponding to the weight of an occupant on an upper side of the foam seat cushion. A humidity sensor responds to relative humidity of air adjacent the pressure sensor and/or foam seat cushion to generate a humidity signal that is used to compensate at least one of the pressure signal, a stored reference pressure value and a stored threshold value, from which at least in part; an occupant classification is determined. The system preferably includes a time delay between the reading of a humidity value and the full use of that humidity value in compensation; and the time delay may be responsive to an activity factor derived from dynamic variations in the pressure signal associated with a pumping action on the foam tending to increase the rate of exchange of air between the foam and the atmosphere outside the foam. Preferably, the temperature adjacent the pressure sensor and/or foam seat cushion is also determined and used in conjunction with the humidity signal to provide au additional cross-correlation compensation.
