Abstract

A method for ascertaining an accuracy of a torque transmitted by a belt-driven starter generator of an internal combustion engine to the internal combustion engine, the method being similar to a learning operation or a calibration of the actual torque of the starter generator with respect to a setpoint torque, includes: in an idling instance of the internal combustion engine, controlling the belt-driven starter generator to transmit a specified test torque to the internal combustion engine and decreasing the torque of the internal combustion engine by the specified test torque; determining and evaluating a speed variable, which is a function of a speed of the internal combustion engine; and deducing the torque accuracy from the evaluated speed variable.
