Abstract
A method for rollover sensing () that may be used in the determination of when to deploy restraints in a vehicle is disclosed herein. The method for rollover sensing () may include lateral acceleration sensors (), a roll rate sensor (), and a roll angle detector (). A control circuit () determines a roll moment of inertia as a function of lateral acceleration, a trip point length as a function of the lateral acceleration, and a trip point angle as a function of the lateral acceleration. The control circuit () also determines a rollover threshold in response to a roll rate signal, a roll angle signal, the trip point length, the roll moment of inertia, and the trip point angle. The control circuit () further generates a control signal for a deployment circuit in response to the rollover threshold.
