Detecting rollover of an automotive vehicle

摘要

A rollover sensing system (12) that may be used in the determination of when to deploy restraints in the vehicle. The rollover sensing system (12) may include lateral acceleration sensors (32), a roll rate sensor (18) and a roll angle detector (20). A control circuit (16) determines a predetermined rollover threshold in response to the roll rate and roll angle detector (20) and calculates an adjusted threshold as a function of the predetermined rollover threshold and the lateral acceleration. The control circuit (16) generates a control signal in response to the adjusted threshold.
