Abstract: The disclosure relates to a method for operating an internal combustion engine. The internal combustion includes an intake manifold via which a cylinder can be supplied with fresh air, an inlet valve via which, when it is open, the fresh air can flow from the intake pipe into the cylinder, and a variable valve drive by means of which the opening duration or the relative timing of the inlet valve event is variable in relation to a crankshaft position. During a starting of the internal combustion engine, when the intake manifold pressure differs from the intake manifold desired pressure, a filling pilot control of the cylinder is undertaken by the variable valve drive by the fresh air supply being reduced in comparison to the fresh air supply at the intake manifold desired pressure. The disclosure further relates to a control device for an internal combustion engine that enables low-emission operation.

Abstract: A method ascertains a characteristic variable of a clutch installed in a drive train of a vehicle for transmitting a transmission torque between a clutch input and a clutch output. A first electric motor is connected to the clutch input and to an internal combustion engine and can assume generator operation, during which it is driven by the internal combustion engine. A second electric motor is connected to the clutch output. The clutch input can have a first rotational speed and the clutch output can have a second rotational speed. The transmission torque during generator operation is ascertained by activating the clutch to adopt a slipping state and in doing so by setting a predefined rotational speed difference between the first and second rotational speed. The clutch input torque present at the clutch input is then ascertained and the transmission torque is determined depending on the clutch input torque.
