Abstract
A rollover sensing system (10) includes a roll rate sensor (14) operative to sense a roll rate of rotation of a vehicle (12) and to provide a roll rate signal having an electrical characteristic indicative thereof. A controller (26) is connected to the roll rate sensor (14) and is operative to determine a roll angle of the vehicle (12) based on the roll rate signal. The controller (26) includes a threshold having a value functionally related to roll angle. The controller (26) determines the occurrence of a vehicle rollover condition in response to the sensed roll rate crossing the threshold.
