Zusammenfassung: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.
