DEVICE AND METHOD FOR DETERMINING THE STARTING CAPABILITY OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to 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, comprising the following method steps: 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 on the basis of the detected first and second battery parameter values, 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.
