    摘要： A method and a device for improving the restart of a vehicle equipped with start-stop operation. In order to accelerate the restart, in a stop phase of the start-stop operation a control unit provides control signals on the basis of which the excitation winding is supplied with a pre-excitation current in the stop phase. In addition, given the presence of a restart request occurring during the slowdown of the internal combustion engine, the control unit checks whether an immediate restart is possible and sensible, and, in the case in which an immediate restart is possible and sensible, initiates an immediate restart, and delays the restart in the case in which an immediate restart is not possible or not sensible.

    摘要： A method for reducing a ripple, caused by rotational nonuniformity of an internal combustion engine, in the output voltage of a generator which is driven by the internal combustion engine is provided. The generator has a stator winding, a rotor winding, a field controller, associated with the rotor winding, for regulating the output voltage of the generator, and a downstream power converter having controllable switching elements. To reduce the voltage ripple, the output voltage of the generator is regulated on the stator side by appropriately controlling the switching elements of the power converter.

    摘要： A method is described for controlling a multiphase machine which is connected to a battery, the multiphase machine having a DC link which is provided with a DC link capacitor, phase windings, and a high side switch and a low side switch for each phase. The switches associated with the individual phases are controlled by a control unit in such a way that sinusoidal phase currents are predefined, at least one phase current is connected at any point in time in each control cycle, and a fixed, pulsed control pattern is present for each control cycle. The control widths of the actuating signals associated with the phases are constant in the pulsed control pattern. The control pulses associated with the individual phases are predefined in such a way that the DC link current which arises is minimized.
