Abstract: A deployment decision for a vehicle restraint system is reached as a function of vehicle dynamics data, at least one vehicle transverse acceleration and one yaw rate about the longitudinal axis of the vehicle being linked to one another as the vehicle dynamics data to reach the deployment decision. The vehicle transverse acceleration is then additionally subjected to a threshold value decision for reaching the deployment decision, the threshold value being set as a function of the integrated vehicle transverse acceleration and the integrated yaw rate.

Abstract: An apparatus for detecting a vehicle rollover includes a sensor suite for sensing vehicle dynamics data, the sensor suite being connected to a processor which is configured in such a way that the processor detects a vehicle rollover as a function of the vehicle dynamics data and the rollover sensor suite. The processor has means for dividing an operating state of the vehicle into chronologically successive phases. In particular, the processor has means for determining, for each phase, a float angle and a transverse vehicle velocity from the vehicle dynamics data; the float angle and the transverse vehicle velocity being used, together with the data from the rollover sensor suite, for detection of the vehicle rollover.

Abstract: A method is provided for generating a triggering decision for a restraint system, in which method the triggering decision is generated as a function of a conjunction of the vehicle lateral acceleration and a rate of rotation. The vehicle lateral acceleration is additionally subjected to a threshold value decision, the respective threshold value being set as a function of at least one component of the velocity of the vehicle's center of gravity.

Abstract: An improved passenger protection is achieved by refining the criterion for triggering the restraining unit provided for impact situations. A system and a method for generating a triggering signal for the restraining unit in a vehicle are provided for this purpose, the restraining unit being provided for the event of a collision of the vehicle—head-on collision, side impact. The system includes a unit for detecting an impact, which, in the event of an impact, generates a request signal for the restraining unit corresponding to the type of impact, and a unit for detecting a rotational motion of the vehicle about at least one vehicle axis—longitudinal axis (x) and/or transverse axis (y)—which generate a corresponding status signal.

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.
