A method for determining the starting capability of an internal combustion engine of a motor vehicle, which can be started by an electric motor powered by a battery, including detecting first battery parameter values during a successful starting sequence of the internal combustion engine at a first time, detecting second battery parameter values at a second time following the first time, determining at the second time the expected battery voltage for a starting sequence of the internal combustion engine taking place at a third time based on the detected first and second battery parameter values, and comparing the battery voltage expected at the third time with a predetermined threshold value in order to derive therefrom the starting capability of the internal combustion engine.

A control unit for actuating a device for triggering a seat belt pretensioner in a vehicle when a rear-end impact occurs includes a sensor device for supplying an acceleration signal a(t) determined at least by a positive acceleration of the vehicle in a direction corresponding to the longitudinal axis thereof, an evaluation circuit for evaluating the acceleration signal a(t) as an evaluated signal and for comparing the evaluated signal with a threshold value, and generating thereby a triggering signal z(t) for the triggering device if the threshold value is exceeded by the evaluated signal y(t), the threshold value having a sign provided for the positive vehicle acceleration.
