Abstract

A method for ascertaining a torque accuracy of a torque transmitted from a belt-driven starter-generator of an internal combustion engine to the internal combustion engine, which is similar to a learning process or a calibration of the actual torque of the starter-generator with respect to a setpoint torque, includes controlling the belt-driven starter-generator to transmit a specified test torque to the internal combustion engine during a predefined test time interval during coasting down of the internal combustion engine, determining a speed variable that is dependent on a speed of the internal combustion during the test time interval, comparing the speed variable to a reference variable, and deducing the torque accuracy from this comparison.
