Abstract
A rollover sensing system ( ) includes a roll rate sensor ( ) operative to sense a roll rate of rotation of a vehicle ( ) and to provide a roll rate signal having an electrical characteristic indicative thereof. A controller ( ) is connected to the roll rate sensor ( ) and is operative to determine a roll angle of the vehicle ( ) based on the roll rate signal. The controller ( ) includes a threshold having a value functionally related to roll angle. The controller ( ) determines the occurrence of a vehicle rollover condition in response to the sensed roll rate crossing the threshold.
