Abstract
A system and method of activating a restraint system of a vehicle is described. The method includes generating a vehicle speed signal that represents a longitudinal speed of a vehicle, generating a lateral acceleration signal that represents a lateral acceleration of the vehicle, filtering the lateral acceleration signal to generate a filtered lateral acceleration signal, comparing the filtered lateral acceleration signal to a predetermined lateral acceleration enable threshold, estimating a lateral speed of the vehicle based on the vehicle speed signal when the filtered lateral acceleration exceeds the predetermined lateral acceleration enable threshold, and activating a restraint system of the vehicle based in part on the estimated lateral velocity.
