Abstract
The system includes pressure sensors disposed within tires of a vehicle. Vehicle maneuvering produces changes in tire pressure between the various tires. The rate and magnitude of changes in tire pressure are utilized to verify and determine vehicle orientation. Changes in tire pressure and the rate of change for the tires provides information utilized for detecting orientation of the vehicle and sensing possible roll over conditions.
