Abstract: In a method and a device for vehicle brake actuation, braking can be actuated as a function of a driver's default value, which can be set by the driver of the vehicle. The default value can be set, in such a way that a braking force dependent on the driver's default value is generated. The braking force actually generated is modified independently of the driver in order to execute an automatic braking sequence when a predefined triggering condition is fulfilled. A limit value for the braking force is determined as a function of the driver's default value, and braking during execution of the automatic braking sequence is actuated independently of the driver in such a way that the modified braking force generated does not quantitatively exceed the limit value determined.

Abstract: A toroidal gearbox in which an annular central disc with a toroidal friction surface and an annular main cylinder of a hydraulic pressure device are located concentrically to a central shaft. A radial partition wall is provided between the central disc and the main cylinder to form two working pressure chambers, the pressurization of which results in axial displacement of the central disc relative to the central shaft to apply contact pressure forces on the friction surface. A pressure piston between the partition wall and the main cylinder having an axial projection effectively bypasses the partition wall and acts on the central disc, in addition to the pressure applied in the pressure chamber between the partition wall and the central disk, thereby achieving an even distribution of the operating force in the circumferential direction, as exerted on the central disc, by the pressure piston.

Abstract: In accordance with a known design, the drive torque of an internal combustion engine is superimposed on a drive torque of an electric drive unit by a planet set to which the drive torque of the internal combustion engine is fed via the sun gear. The torque of the electric drive unit is transferred for different shift positions of a clutch by driving different ring gears of the planet set. A drive train which is improved in terms of the operating ranges may be provided by having the electric drive unit be coupled directly to the input shaft via a clutch or coupled to a sun gear of the pick off gear unit via a clutch. This provides improved operation when the drive train is operated on the one hand as a conventional automatic transmission and on the other hand as an infinitely variable transmission with two driving ranges.
