Abstract

A method for activating a passenger safety application in a vehicle involves a rotational acceleration sensor device which is used to obtain a measurement of the rotational acceleration &agr;x of the vehicle, e.g., about an axis of rotation x parallel to the longitudinal axis of the vehicle. The results of this measurement are analyzed by a computing unit for evaluating the vehicle situation with respect to its surrounding. Activation of a suitable safety application is performed in the event that the analysis indicates that a rollover event of the vehicle is imminent.
