Abstract: The invention relates to a diagnostic method for self-excited generators, in which a diagnostic decision is made by means of field current monitoring.

Abstract: The invention relates to method for operating a drive system for a motor vehicle comprising an internal combustion engine (1) and an electric machine (6), it being possible to accelerate a driveshaft (4) of the internal combustion engine by means of the electric machine (6), and in the event of an upshift and/or when an upshift is initiated, an idling rotational speed of the driveshaft (4) is increased by the electric machine (6). If a turbocharger is used to increase the charge pressure, an increase in the idling rotational speed by the electric machine can compensate for low efficiency of the turbocharger at low rotational speeds.

Abstract: The present invention discloses a power supply circuit for a motor vehicle electric system having a starter generator (1), a power electronics system (LE), at least one battery (B), at least one dynamic energy accumulator (3) and a DC/DC converter (2). The power supply circuit has a first connection branch which is provided with the DC/DC converter (2) and is connected to a terminal of the dynamic energy accumulator (3) and a second connection branch which is connected to a terminal of the battery (B). Both connection branches can be disconnected from the starter generator (1) by means of controllable switches (S1, S2).
