摘要： 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.

摘要： 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.
