Abstract: A method is provided for producing a locally-reinforced profile component. The method includes the following steps: providing a primary profile to be reinforced which is made of fiber-reinforced plastic; providing a secondary profile made of plastic for local reinforcement of the primary profile; arranging the secondary profile on an outer surface of the primary profile to create the profile component; heating the profile component (IO); integrally-bonded connecting of the primary profile and the secondary profile by applying pressure to an outer surface and simultaneous use of a counter pressure to apply pressure to an inner surface of the profile component.

Abstract: A control unit for a vehicle includes an electric energy store for storing electric energy for an electric drive machine. The control unit is designed to determine that the vehicle is driving to a charging station in order to charge the energy store. In response to the determination, the control unit is additionally designed to initiate one or more usage-neutral or usage-reducing measures while the vehicle is traveling in order to reduce the temperature of the energy store in preparation for the charging process of the energy store.

Abstract: A method is provided for plastic forming of a ball which forms a connecting element or part of a connecting element intended for connecting at least two components. At least some of the energy required for the plastic forming of the ball is introduced into the ball by way of ultrasound.

Abstract: A method is provided for joining a fiber-reinforced joining element, formed from a plastic material, to the joining surfaces thereof by way of an ultrasonic welding method. A concentrator and/or at least one insertion element is arranged in the region of the joining surfaces prior to fusing between the joining surfaces, and the concentrator and/or the insertion element are fused together with the joining surfaces in order to form a positive fit joint therewith after hardening.

Abstract: A method is provided for producing a component connection. The method includes the following steps: providing a first component, providing a first ball, pressing the first ball against the first component by a sonotrode, vibrating the first ball by the sonotrode such that material of the first ball and/or material of the first component melts, and the first ball is welded to the first component, providing a second ball, pressing the second ball against the first ball by the same sonotrode or another sonotrode, and vibrating the second ball by the same sonotrode or the other sonotrode such that material of the second ball and/or material of the first ball melts, and the second ball is welded to the first ball.

Abstract: A method is provided for welding a ball to another component. The method includes: providing a sonotrode which has a trough-shaped recess, in particular a spherical cap-shaped recess; pressing the ball against the other component by the sonotrode, the ball protruding into the trough-shaped recess; and vibrating the ball by the sonotrode such that material of the ball and/or material of the other component melts, and the ball is welded to the other component.
