Abstract: A method of adapting control of clutches of a double clutch transmission, including: during a shifting process, controlling torque transmittable by an opening clutch and torque transmittable by a closing clutch according to nominal curves; during a shifting process, determining a difference between a nominal value and an actual value; and adapting a nominal curve of at least one of the clutches for a following shifting process by reducing a difference between the nominal value and the actual value.

Abstract: A method for controlling a drivetrain in a motor vehicle which has an internal combustion engine with a crankshaft, an automated gearbox with engagable and disengagable gears and a gearbox input shaft and a gearbox output shaft which drives drive wheels, a friction clutch which connects the crankshaft and the gearbox input shaft in a separable manner and is operated in an automated fashion, and a control unit for controlling the drivetrain. For driving comfort, before the vehicle comes to a stop, a starting gear is engaged in an overrun mode such that, after opening the friction clutch, a synchronization of gearbox input and output shaft rotational speed of the starting gear is initiated at a gearbox input shaft rotational speed which is higher than a target rotational speed of the gearbox input shaft yielded by the transmission ratio of the starting gear between the gearbox input and output shaft.

Abstract: A method for determining an error in engine torque, wherein at least before and after a predetermined change in the engine torque the change in engine speed is registered, and this is compared with the engine torque before and after the change in the engine torque.

Abstract: A method is described for controlling a clutch which is located between a drive motor and an automated manual transmission of a drive train. In this method, vibrations during load alternations are reduced by controlling the clutch so that a free-wheeling function is implemented during an engine braking mode.

Abstract: The invention relates to a method for graphically processing an image of the surroundings of a motor vehicle, the image being been provided by a camera device. It is known fact that said images are processed in such a way that the danger potential for the motor vehicle posed by an obstacle in the surroundings is visualized optically by or highlighted for the driver. According to the invention, the image provided by the camera device is processed taking into account the position of the obstacle in the image in order to highlight said danger potential in an even clearer manner for the driver. To this end, the actual position of the obstacle in the surroundings of the motor vehicle is initially determined. The position of the obstacle in the image corresponding to the actual position of the obstacle in the surroundings is subsequently determined.

Abstract: The invention relates to a method and device for securely and comfortably operating a drive train of a motor vehicle, especially for operating a drive train with several clutches.

Abstract: The invention relates to a method for shifting an initial gear upwards into a target gear in a twin-clutch gearbox of a motor vehicle. According to the invention, the engine torque (MMotor) of the vehicle is altered when a target gear is selected incorrectly and detected thus. The output torque (MOutput) is then reduced if the correct target gear is introduced. The invention also relates to a twin-clutch gearbox, especially for carrying out said method.

Abstract: A powershift transmission is proposed using two transmission paths, a friction clutch being assigned to each transmission path and the transmission paths being coupleable to an output shaft for torque transmission. The transmission has a device that detects the clutch torque transmitted by the friction clutch of the active transmission path, which is coupled to the output shaft, and, when the clutch torque falls below threshold value, initiates a disengagement of the active gear ratio.

Abstract: The invention concerns an arrangement for carrying out steering angle or steering wheel angle measurements (&agr;) in motor vehicles. The arrangement uses a resolver for transmission purposes. Advantageous developments concern the use of the resolver for the additional transmission of switching information in both directions and for transmission of energy using frequency-separated or time-multiplexed transmission channels.
