1. A method for protecting against rollover in a motor vehicle comprising the steps of: providing an array of linear acceleration sensors at predetermined locations relative to the center of gravity of the vehicle; providing a control module having a model of the vehicle dynamics and a model of the array of sensors; detecting an acceleration for each sensor in the array of sensors; estimating a roll angle of the vehicle based on the detected accelerations, the model of the vehicle dynamics and the model of the sensors; generating a control signal based on the roll angle; and reducing the roll moment of the vehicle based on the control signal.
