  • Method for ascertaining a viscosity of a fuel
    Patent number: 10697877
    Abstract: 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.
    Type: Grant

  • Method for ascertaining a position of a rotor of an electrical machine
    Patent number: 9885590
    Abstract: 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.
