Abstract

The invention relates to processing unit for monitoring an electrically operated starter which is designed to drive an internal combustion engine during a starting process. The processing unit is designed to determine information relating to power with respect to the electric power which is fed to the starter during a starting process of the internal combustion engine. The processing unit is also designed to determine information relating to the rotational speed with respect to the rotational speed of the internal combustion engine during the starting process. The processing unit is further designed to perform a diagnostic of the starting process and/or the starter based on power information of the rotational speed information.
