1. A safety device comprising:
- a controller configured to;
receive lateral momentum information and suspension information to assess vehicle movement prior to a vehicle experiencing a rollover event;
receive at least one passive signal indicating that the vehicle is experiencing the rollover event; and
detect that the vehicle is experiencing the rollover event based on the lateral momentum information, the suspension information, and the at least one passive signal,wherein the lateral momentum information is determined by m*vlateral,where m is defined as an overall weight of the vehicle including all occupants positioned therein and vlateral is defined as a lateral velocity of the vehicle.

Abstract
A system and method for deploying one or more airbags in a vehicle is provided. The system comprises a passive detection device, an active detection device and a controller. The passive detection device is configured to present one or more passive signals indicative of the motion of the vehicle after the vehicle has experienced an impact. The active detection device is configured to present suspension information related to the vehicle that is indicative of the motion of the vehicle prior to the vehicle experiencing an impact. The controller is configured to predict vehicle impact and deploy the airbags in response to the suspension information and the one or more passive signals.
