Development of an Automotive Rollover Sensor 2000-01-1651
It is estimated that in the United States, nearly one quarter of all fatal automobile accidents involve a vehicle rollover.  In order to reduce fatalities and serious injuries, it is desirable to develop a sensing system that can detect an imminent rollover condition with sufficient time to activate occupant safety protection devices. The goals of a Rollover Sensing Module (RSM) are;
To accurately estimate vehicle roll and pitch angles
To reliably predict in a timely manner an imminent rollover
To eliminate false activation of safety devices
To function properly during airborne conditions
To be as autonomous as possible, not requiring information from other vehicle subsystems.
