A method for ascertaining a viscosity of a fuel with the aid of an electric fuel pump which is integrated into a fuel circuit including an overflow valve which includes a permanently open discharge channel, a fuel supply and delivery being adjusted with the aid of the electric fuel pump in the fuel circuit at a specific pressure and the viscosity of the fuel being ascertained by taking into account a delivery rate of the electric fuel pump.

Method for ascertaining a viscosity of a fuel

A method for detecting an electrical fault in a current supply of a consumer, where a transition resistance of the current supply allocated to the consumer is determined from a local voltage value allocated to the consumer, a local current value allocated to the consumer, and a global voltage value, and compared to a resistance threshold value allocated to the consumer, and an electrical fault in the current supply of the consumer is detected as a function of the comparison result.

Method for detecting electrical faults in a current supply of a consumer

A method for ascertaining a position of a rotor relative to a stator of an electrical machine having a permanently excited rotor and a plurality of windings for the stator or vice versa; in response to an energization of at least one of the windings, a change in an inductance of the winding being ascertained; and, on the basis of the change in the inductance of the winding, the position of the rotor being ascertained relative to the stator.
