1. A method for predicting vehicle rollover and activating an occupant restraint system, the method comprising:

  • receiving input signals for early detection of one or more of a vehicle position and vehicle movement that indicate a potential for vehicle rollover;

    determining, based on at least some of the input signals, when a first pre-rollover stage threshold has been met;

    activating at least a first resettable restraint device when the first pre-rollover stage threshold has been met;

    determining, based on at least some of the input signals, when a second pre-rollover stage threshold has been met;

    activating at least another resettable restraint device when the second pre-rollover stage threshold has been met;

    determining, based on at least some of the input signals, when a first rollover stage threshold has been met;

    activating at least a first non-resettable restraint device when the first rollover stage threshold has been met;

    determining, based on at least some of the input signals, when a second rollover stage threshold has been met; and

    activating at least another non-resettable restraint device when the second rollover stage threshold has been met.
