Abstract: An energy storage device for a motor vehicle includes a first energy store and a second energy store for storing electrical energy, a charging connection for charging the energy stores, an operating connection for operating a load on the energy storage device, and a switching device which has a plurality of switching elements and via which the energy stores can be connected selectively in series or in parallel. A fifth switching element of the switching device is permanently electrically coupled to the electrical poles of opposite polarity of the energy stores and the energy stores can be connected in series via the fifth switching element independently of the other switching elements of the switching device.

Abstract: A valve train device, particularly for an internal combustion engine, includes a camshaft, a cam element able to be displaced axially on the camshaft, and a mechanical displacement element which is provided on the camshaft for the purpose of axially displacing the cam element. The mechanical displacement element is provided to move the cam element by interaction with only a single contour of the cam element in a first and a second axial direction.

Abstract: A valve drive device, in particular for an internal combustion engine, includes a support element fixed to a housing and at least one axially shiftable cam unit allocated to a valve. The cam unit has at least three cam tracks. At least one switching unit which is a displacement body is provided to displace at least one part of the cam unit in the direction of a first actuation direction for axial shifting. The displacement body displaces at least one part of the cam unit in the direction of a second actuation direction opposing the first actuation direction.

Abstract: An engine block for an internal combustion engine of a motor vehicle has a cylinder within which a piston can be movably accommodated between a top dead center and a bottom dead center and has a cylinder bore, the internal cylinder diameter of which expands in the direction of the bottom dead center. The internal cylinder diameter expands only below the region in which a piston system change takes place during operation of the internal combustion engine. The internal cylinder diameter tapers from the top dead center to the region.

Abstract: A shelving system for a motor vehicle has at least one shelf, which includes a base unit with a base element supported in a base position allocated to the base element on a support element and is mounted on a pivoting axis. The base element can be shifted around the axis out of the base position allocated to it into an access position allocated to the base element, in which the base element is raised by the at least one support element. A further base element is supported in a base position allocated to the further base element on the support element and is mounted on a further pivoting axis arranged on the side of the support element opposite the first pivoting axis. The further base element can be shifted into an access position, in which the further base element is raised by the support element.
Abstract: A method for controlling a positive gearshift unit includes, in an engagement procedure, a coupling element, which is connected to a first coupling half and which has a beveled coupling toothing, is brought into engagement with a blocking element, which has a blocking toothing and which is connected to a second coupling half, and is brought into engagement with a catch element, which is connected to the second coupling half, which has a beveled catch toothing, and which is able to move circumferentially with respect to the blocking element. In the engagement procedure, a touch-point is set which comes after a crossing of a synchronous rotational speed in a rotational speed difference profile.
Abstract: Structures and methods are disclosed for removing water, and particularly for preventing ice blockages, in solid polymer electrolyte fuel cells comprising reactant vias that fluidly connect a reactant transition region to a reactant port. Water can be removed from the reactant via by making its surface superhydrophobic while incorporating at least one additional via with a hydrophilic surface in parallel therewith.
Abstract: A method for deactivating an automated driving function of a vehicle, in particular a highly automated or autonomous driving function, is provided. The driving function is deactivated when a driver of the vehicle carries out a steering intervention or pedal intervention with a strength exceeding a predeterminable deactivation threshold. The deactivation threshold is predetermined depending on an operation length of the driving function and/or depending on a responsiveness of the driver. In particular, the deactivation threshold is predetermined in such a manner that it is higher directly after an activation of the driving function than some time afterwards and/or it is higher with a low responsiveness of the driver than with a high responsiveness of the driver.
