The disclosure relates to a power circuit for power supply in an electrically driven vehicle. The power circuit includes a direct voltage connection, an electrical traction drive, and a DC/AC converter. The converter includes an alternating voltage side connected to the traction drive. A DC/DC converter of the power circuit includes two converter sides. The first converter side is connected to a direct voltage side of the DC/AC converter via a coupling point. The direct voltage connection is likewise connected to the coupling point. The disclosure further relates to a stationary energy supply system designed to be complementary and to connect to the power circuit.

A control unit for a vehicle component, such as a transmission, is constructed by transferring electronic components from a rigid circuit board to a flexible circuit board. The flexible circuit board is guided through a housing that accommodates the rigid circuit board and a portion of the flexible circuit board. Some electronic components are disposed on the rigid circuit board and some electronic components are disposed on the flexible circuit board.

An electrical coupling state is monitored between an inductive load and a circuit configuration. The latter has a first and a second coupling point for coupling to the inductive load. A first voltage value is determined between the first and second coupling points. The first voltage value is tested for the occurrence of a characteristic voltage pulse, which can be triggered by reduction of a magnetic flux in the inductive load by way of a steep-edged change in the amount of current flow through the inductive load. An error is identified in the coupling state if the characteristic voltage pulse does not occur within a predefinable time period. The absence of an error in the coupling state is also identified if the voltage pulse does occur.

The system allows locating an enabling component of a motor vehicle. The enabling component, provided with a chip, is for example a smart card or an electronic key. The enabling component is addressed with a search signal from a transmitter fixed to the vehicle. The enabling component responds with an indicating signal. The indicating signal may be an audible signal emitted by the enabling component itself and/or the location information can be indicated by an indicator device fixed to the vehicle.
