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.

Abstract: A bearing includes an inner ring, an outer ring, and a plurality of rollers. The rollers separate the inner ring from the outer ring. The outer ring has an outer radial surface with a circumferentially continuous portion and a plurality of axial projections extending from the circumferentially continuous portion. To improve the security of the press fit connection between outer ring and a housing, surfaces of the outer ring which contact the housing are treated with a laser etching process. The laser etching may be applied to the circumferentially continuous portion and/or to the outer surface of the axial projections. The laser etching process removes a small amount of material from the surface, creating valleys. The removed material is clumped on its surroundings, building peaks. The peaks and valleys increase the friction between the outer ring and the housing, reducing the chance of failures.
