Vehicle rollover prediction with occupant restraint system activation
First Claim
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;
activating at least a first resettable restraint device when a first pre-rollover stage threshold has been met, based on a comparison with at least some of the input signals;
activating at least a second resettable restraint device when a second pre-rollover stage threshold has been met, based on a comparison with at least some of the input signals;
activating at least a first non-resettable restraint device when a first rollover stage threshold has been met, based on a comparison with at least some of the input signals; and
activating at least a second non-resettable restraint device when the second rollover stage threshold has been met, based on a comparison with at least some of the input signals.

Abstract
An automobile rollover prediction and restraint device deployment system comprises a plurality of automobile data sensors to generate a plurality of data signals, and a controller to receive the data signals and configured to deploy resettable and non-resettable restraint devices. The controller is configured to activate at least one resettable restraint device when one or more of the data signals exceed a first threshold, indicating that the vehicle is in a position or undergoing movement that indicates a potential for vehicle rollover, and to de-activate the at least one resettable restraint device when one or more of the data signals fall below the first threshold.

7. A method for detecting one or more of a vehicle position and vehicle movement that indicate a potential for 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; and activating restraint devices as each of at least three thresholds are met, based on a comparison of at least some of the input signals, prior to initiation of vehicle rollover to keep vehicle occupants from moving within the vehicle to positions that are less suitable for inflatable restraint device deployment. - View Dependent Claims (8, 9, 10, 11, 12, 13)
