Abstract: A method performs shifts in a dog clutch element of a transmission system in a hybrid vehicle. The vehicle has an input shaft being connected to a crankshaft of an internal combustion engine, an output shaft being connected indirectly to driven wheels, an electric machine which is in engagement with the input shaft, and an automatic transmission connected between the input and output shafts. The transmission has a dog clutch element for the releasable coupling of two transmission elements. During a desired shifting of the dog clutch element, the torque of the input shaft is adapted via the electric machine, and therefore a reduced load prevails in the region of the dog clutch element and the latter can be disengaged, after which the internal combustion engine is set to a desired target rotational speed, and after which the dog clutch element is engaged when the target rotational speed is reached.

Abstract: A joint-sealing element is useful for fireproof sealing of building-structure joints, especially for fireproof sealing of a joint between a first building part and a second building part, with a carrier element and a sealing profile disposed on this carrier element, wherein the disposed sealing profile contains an intumescent material.

Abstract: A hybrid vehicle is operated with a combustion engine, an electric machine and a gear unit. The vehicle has a first electrical system and a second electrical system as a vehicle electrical system. The first electrical system, which is operated at a higher voltage level than the second electrical system, operates the electric machine, an electrical energy storage device, an energy converter that transmits electrical power at least from the first electrical system into the second electrical system. An alternator is not used in the second electrical system. The first electrical system is a part of a transmission system that together with the components that are coupled to the transmission system is controlled by a transmission control unit. During power generation by the electric machine the energy supply of the second electrical system has a higher priority than a motor-mode support of the drive by the electric machine.

Abstract: A method for producing vehicle seat components involves working a semifinished blank in a cutting manner. The method can be carried out easily and at low cost and makes it possible to produce components that require little reworking and also provides a vehicle seat component that is both suitable for reducing crash energies by deformation and has an adequate wear resistance. The method includes local heating of the semifinished blank in the region of an intended cutting line of the vehicle seat components to be cut out and cutting out the vehicle seat components from the semifinished blank along the cutting line during or shortly after the heating.

Abstract: A joining process is proposed for connecting a first component to a second component, whereby in a first process the first component and the second component and an adhesive material arranged between the first and the second component are prepared, whereby in a second process the first and the second components are pressed together and whereby in a third process the adhesive material is hardened and further whereby spacing means are added to the adhesive material and these are at least partially resorbed in the third process by the adhesive material.

Abstract: The present invention relates to a joint-sealing tape with an elongated carrier and at least two separate sealing elements of predetermined width, which are disposed on one side of the carrier, spaced apart, side-by-side and running in the longitudinal direction of the carrier, and which each have two oppositely disposed broad sides as well as two narrow sides running transversely relative to the broad sides and connecting them, wherein the sealing elements are disposed with one broad side on the carrier, wherein the sealing elements are each joined firmly to the carrier only via part of their broad side. Furthermore, the invention relates to a sealing arrangement for sealing of building structure joints, especially for sealing against sound and/or smoke and if applicable against fire, with such a sealing tape.
