Abstract

A control unit is provided for a hybrid drive that includes an internal combustion engine and an electric machine. The control unit is configured to cause one or more drag torque reduction measures of the internal combustion engine to be terminated in preparation for firing the internal combustion engine. In addition, the control unit is configured to cause the electric machine to at least partly compensate for an increase in the drag torque of the internal combustion engine caused by the termination of the one or more drag torque reduction measures.
