In a method for operating a starter of a vehicle, a position of a starter pinion is detected, and an advance of the starter pinion is regulated as a function of the detected position. For example, the advance during the meshing of the starter pinion with a starter ring gear of a drive motor of the vehicle is regulated.

Method and device for operating a starter of a vehicle

A diagnostic device is provided for a multi-voltage electrical system of a motor vehicle which has a first subnetwork acted on by a first voltage and a second subnetwork acted on by a second voltage, the first voltage being higher than the second voltage, and the first and the second subnetwork having a shared ground connection. The diagnostic device includes a second ground connection, a measuring unit configured to measure a current flow via the second ground connection, and a diagnostic unit configured to diagnose a disturbance in the shared ground connection and/or in the second ground connection on the basis of the measured current flow via the second ground connection as a function of at least one operating state of the vehicle electrical system.

A method and a circuit system for operating an electric machine are presented. The method is carried out in particular in a starting phase, a current being limited using a controllable resistor, the controllable resistor being implemented by at least one semiconductor switch, which is controlled using a clocked signal, and the signal being set in such a way that in shutdown phases, the at least one semiconductor switch is not completely shut down.

Method for operating an electric machine

A method for detecting the state of electrical connection of an energy store, e.g., a battery, to a vehicle's electrical system includes ascertaining operating variables, e.g., battery current Iand generator current I, essentially in time synchronous fashion. When there is a change in the generator current Iof the generator during a transitional time, the energy store is checked for the value of the battery current Ifor the detection of a compensating effect in the form of a current delivery or a current consumption.
