A rollover condition is detected responsive to the comparison of a figure of merit with a threshold, wherein the threshold is given generally as a function of a period of time commencing with a time of inception determined from one or both of a measure of lateral acceleration and a measure of angula

A rollover condition is detected responsive to the comparison of a figure of merit with a threshold, wherein the threshold is given generally as a function of a period of time commencing with a time of inception determined from one or both of a measure of lateral acceleration and a measure of angular velocity. The measures of lateral acceleration and angular velocity are filtered, and are compensated to remove offset errors. In one embodiment, the figure of merit comprises a measure function that incorporates a damping term and a product term. The product term comprises a force measure and a kinetic energy measure, wherein the force measure is responsive to the measure of lateral acceleration, and the kinetic energy measure is responsive to the measure of angular velocity. The product term may further comprise a potential energy measure that is responsive to a measure of roll angle.
