Abstract

A device and a method for triggering passenger protection systems, the passenger protection systems being triggered as a function of a rollover process. A signal which characterizes a road grip coefficient (coefficient of friction) is received via an interface. An evaluation circuit is provided which triggers the passenger protection systems as a function of the signal and a stability factor, the evaluation circuit determining the stability factor as a function of at least one kinematic variable.
