Abstract: A method for verifying a drive torque applied by an electric machine in a hybrid drive of a motor vehicle, the motor vehicle being propelled by the electric machine and/or an internal combustion engine, and it being checked if the drive torque applied by the electric machine is determined accurately. In order to ensure that the operating strategy is correctly implemented and a shift in load level in the power train functions reliably during operation of the motor vehicle, the drive torque applied by the electric machine is evaluated with regard to its accuracy, using a drag torque generated by the combustion engine during an overrun fuel cut off.

Abstract: In a method for actuating an actuating member for adjusting a turbine flow cross section of a turbocharger of an internal combustion engine in a motor vehicle in the event of a change of the load of the internal combustion engine from a relatively low load value to a relatively high load value, the adjustment takes place at least at times by use of the closed-loop control of a scavenging gradient of the internal combustion engine. The method is characterized in that the turbine flow cross section, in the case of a spark-ignition engine as the internal combustion engine, is not fixedly held at a minimum turbine flow cross section between the change of the load and a beginning of an adjustment which is dependent on the scavenging gradient. A control unit is set up and controls the process of such a method.
