Abstract: The invention relates to a method and a device for the generation of checkable forgery-proof documents with an externally supplied cryptographic module, whereby the checking of authenticity of the document is carried out without using key information belonging to the cryptographic module. According to the invention, the method and the device are characterised in that the cryptographic module is supplied with two types of data, even on supply from a communication partner which is cryptographically not trustworthy, which either remain in the cryptographic module or are attached to the document. The information remaining in the cryptographic module is used to secure the document information by means of a check value and the information transferred into the document serves to verify the securing of the document by the cryptographic module during a check of the authenticity of the document at a checkpoint.

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.

Abstract: 1. A method for operating the drive train of a motor vehicle. 2.1. In a known method, with the friction clutch completely closed, a control device monitors rotational speeds upstream and downstream of the clutch. As soon as slip occurs, the control devices reduces an output torque of an engine for a limited time. The object of the invention is to propose a method, by means of which, while adhering as much as possible to a torque instruction of a vehicle driver, damage to the friction clutch and to further components of the transmission is avoided. 2.2 According to the invention, with the friction clutch slipping, the control device determines an energy quantity dissipated in the friction clutch and/or a temperature of the friction clutch. If the dissipated energy quantity and/or the temperature overshoot limit values, the control device reduces the output torque of the engine. According to a second embodiment, the output torque of the engine is reduced in steps. 2.3 Use in a motor vehicle.
