  • Supply device for a motor vehicle
    Patent number: 10800271
    Abstract: A supply device for a motor vehicle has a DC/DC converter and a control device for the DC/DC converter. The DC/DC converter has first terminals and second terminals, which first terminals are configured for electrical connection to a first energy storage or a first energy source and which second terminals are configured for electrical connection to a second energy storage or a load. The DC/DC converter is configured, in a first state to enable a conversion of a first DC voltage at the first terminals into a lower second DC voltage at the second terminals and, in a second state, to carry out no conversion of a first DC voltage at the first terminals into a lower second DC voltage at the second terminals. The control device enables an energy supply at the second terminals by repeatedly changing the DC/DC converter between the first state and the second state.

  • Method and device for ascertaining a rotational speed parameter for determining a setpoint torque
    Patent number: 8527168
    Abstract: A method for ascertaining a rotational speed parameter for determining a setpoint torque for driving a drivetrain. The drivetrain comprises a first and at least one second drive assembly for driving a hybrid vehicle. The first drive assembly can be coupled to the drivetrain by means of a clutch. The second drive assembly is mechanically coupled to the drivetrain. When the hybrid vehicle is being driven by means of at least the first drive assembly, the rotational speed parameter corresponds to the value of a shaft rotational speed. When the hybrid vehicle is being driven only by means of the second drive assembly, the rotational speed parameter corresponds to the value of a determined rotational speed.
