Abstract: A method and a control device for triggering passenger protection devices for a vehicle are provided, a rollover event causing the triggering of the passenger protection devices. The rollover event is detected as a function of kinematic and rotation variables, an adhesion, and a static stability factor. A state of rotation is ascertained via a rotation rate and a rotation angle. A state of adhesion is ascertained from a vehicle transverse acceleration and a vehicle vertical acceleration. The rollover event is detected via the state of adhesion and the state of rotation, the adhesion being much greater than the static stability factor.

Abstract: In a method for activating a passenger protection unit for a vehicle, features are generated from at least one sensor signal of a crash sensor system. Furthermore, a difference of a feature vector with a first threshold value is formed. This difference is weighted as a function of at least one of the features. The passenger protection unit is subsequently activated as a function of a comparison of a variable, derived from the weighted difference, with a second threshold value.

The transponder includes at least one transponder chip and a transponder antenna and is embedded in a substrate which is connected to an inner side of the tire with the aid of an element. The aim of the invention is to provide a transponder with the highest possible durability. To achieve this, the connecting element is a material strip which is only fixed to the inner side of the tire in one sub-section.
