Abstract: In a twin-clutch transmission, in a first forward gear, the drive torque is transferred by an interconnection of a first transmission part having one countershaft and a second part transmission having another countershaft by means of an intermediate stage whose gearwheels can be used multi-functionally in connection with additional forward gears of the transmission thereby providing for a relatively small transmission with a relatively large number of transmission ratios.

Abstract: The invention relates to a method for actuating a traffic-adaptive assistance system in a host vehicle, using speed-related and/or distance-related variables of the vehicle and of a preceding vehicle, to control acceleration or deceleration of the vehicle. If the actual time interval or the actual distance between the vehicle and the preceding vehicle is greater than a predefinable respective lower limiting value and smaller than a predefinable respective upper limiting value the assistance system is actuated without regard to an otherwise applicable target time or distance time interval.

Abstract: A method and apparatus are provided for switching on and off the internal combustion engine which drives a vehicle by way of a manual transmission.

Abstract: A method for reconstructing the profile of structures on surfaces. According to said method, at least two images of the same area of the surface that is to be analyzed are evaluated, said images being recorded from a nearly vertical perspective, for example, and the surface being illuminated from different directions at a flat angle thereto. Elevations or depressions on the surface thus cast a distinct shadow in the recorded images, the position of which varies according to the incident light. Inclined areas can be identified by means of a brighter reflection. The vertical profile of a structure on the surface can be determined, and the shape of a fin can hence be reconstructed, for example, by analyzing shadow contours and outlines of bright areas. Even flat inclination changes can be determined by integrating the shape-from-shading process so as to evaluate brightness patterns such that a 3D reconstruction of the surface can be obtained, which matches the original well.
