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 controlling a bridge rectifier which includes active switching elements is provided, in which, during normal operation, at least one of the active switching elements is controlled using a voltage signal, the voltage of which is changed from a first voltage value to a second voltage value within at least one switching time. The at least one switching time is extended by a predefinable time period if load shedding at the bridge rectifier is determined. Also described is a corresponding rectifier system and a computer program product.

摘要： A method for measuring the temperature of a permanent magnet disposed on a rotor of an electrical machine, a magnetic property of the permanent magnet dependent on the temperature of the permanent magnet being sensed and the temperature of the permanent magnet being ascertained therefrom, and to an electrical machine, a processing unit, and a computer program for carrying it out.
