Abstract: A vehicle crash sensing system (20) and method are provided for sensing a vehicle crash event. The system (20) includes a linear acceleration sensor (22) located on a vehicle (10) for sensing linear acceleration (A Y ) along a first sensing axis (Y) and generating a linear acceleration signal. The system (20) has linear crash sensing logic (50) for determining a crash event along the first sensing axis (Y) as a function of the sensed linear acceleration. The system (20) also has signal processing circuitry (26) for processing the linear acceleration signal and generating a processed linear acceleration signal. The system (20) has an angular rate sensor (32) located on the vehicle (10) for sensing an angular roll rate ( φ̇ x ) of the vehicle (10) about a second sensing axis (X) and generating a roll rate signal. The system (20) further includes rollover crash sensing logic (70) for determining a rollover event of the vehicle (10) about the second sensing axis (X) as a function of the processed linear acceleration signal and the roll rate signal.

Abstract: A rollover warning and detection method for a transport vehicle (10) is adaptively adjustable to take into account the CG height of the vehicle. Measures of the vehicle speed, lateral acceleration and yaw rate are sampled during normal driving conditions and used to estimate the CG height of the vehicle (18, 20, 22, 36, 40). The centrifugal acceleration acting on the vehicle is calculated as the product of vehicle speed and yaw rate (36), and the CG height is estimated based on the relationship between the calculated centrifugal acceleration and the measured lateral acceleration (40). The estimated CG height of the vehicle is used to adjust various calibrated rollover detection thresholds (50, 52) so that algorithm outputs such as rollover warnings automatically take into consideration vehicle loading effects.

Abstract: An arming signal for enabling deployment of rollover safety devices (28) by a vehicle rollover detection apparatus (20, 26) is based on an off-axis measure of vehicle acceleration. A low-g accelerometer (22) mounted perpendicular to the longitudinal axis of the vehicle (10) but at an angle with respect to Earth's ground plane detects components of both lateral and vertical vehicle accelerations. The measurement angle is selected to apportion the lateral vs. vertical measurement sensitivity in accordance with calibrated lateral and vertical acceleration thresholds, and an arming signal is generated when a filtered version of the measured acceleration exceeds an arming threshold (40, 42, 44, 48).
