Abstract
A vehicle rollover event detector ( ) includes an accelerometer ( ) that senses vehicle acceleration in a direction offset from a front-to-rear axis of the vehicle ( ) and provides an acceleration signal ( ) indicative thereof. A rollover sensor ( ) senses vehicle roll and provides a roll signal ( ) indicative of vehicle roll about the front-to-rear axis of the vehicle. A controller ( ) compares the roll signal ( ) against a first rollover threshold ( ) when the acceleration signal ( ) is less than an acceleration threshold ( ) and compares the roll signal ( ) against a second rollover threshold ( ) when the acceleration signal ( ) is equal to or greater than the acceleration threshold ( ) and for indicating a vehicle rollover condition when the roll signal is greater than the threshold ( ) it is compared against.
