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.
