Abstract: The invention relates to an arrangement and a method for controlling an adjusting speed for a change of an actual transmission ratio into a steady-state desired transmission ratio (shifting operation) for a continuously variable transmission mounted in the drive train of a motor vehicle. In the arrangement of the invention, it is provided that the shifting operation is subdivided into individual periods (dT) of fixed duration. During each period (dT), a dynamic desired transmission ratio (udyn) is determined by multiplying the steady-state desired transmission ratio (ustat) by a gradient (udot). The change of the actual transmission ratio (u) into a dynamic desired transmission ratio (udyn) of each period (dT) takes place with a constant adjusting speed (vu).

Abstract: The invention proceeds from a motor vehicle having a drive train and the elements of the drive train are rotatable. The determination of a quantity, which represents the traction resistance, takes place in such a manner that an acceleration quantity is detected. This acceleration quantity represents the instantaneous acceleration of the vehicle. Furthermore, a reference quantity for the acceleration of the vehicle is detected and the quantity, which represents the traction resistance, is determined in dependence upon a comparison of the detected acceleration quantity with the determined reference quantity. The essence of the invention is that a rotation quantity is determined which represents the rotation torque of at least one element mounted in the drive train. The determination of the reference quantity takes place in accordance with the invention in dependence upon the determined rotation quantity.

Abstract: The invention proceeds from a system for considering differing amounts of components for determining at least one control quantity such as for controlling the operation of a motor vehicle. Such a system is known from the state of the art wherein a value is determined as a control quantity for the adaptive transmission control. This value characterizes the type of driver or the driving style.

The determined components are then supplied to at least one collector which forms the evaluation quantity, for example, by maximum formation, weighted and/or moving-window sum formation of the individually determined components. The essence of the invention is that means are provided with which the supply of the components of the supply objects is controlled to the collector.

Abstract: Process for forming an aluminum alloy strip, including the steps of a) obtaining an aluminum alloy consisting essentially of, by weight, 0.5 to 13% Si, 0 to 2% Mg, 0 to 2% Cu, 0 to 1% Mn, 0 to 2% Fe, other elements less than 0.5% each and less than 2% total, and remainder Al; and b) continuously casting the aluminum alloy between twin cooled rolls having a force applied thereto, to obtain a cast strip of thickness between 1.5 and 5 mm, and optionally cold rolling the cast strip.

Abstract: A method of encoding invisible identification code into an image, which is highly resistant to degradation across communications links, and which does not require the presence of the original image for decoding, comprises analyzing the image and determining strongly featured regions such as edges, and inserting code into such regions by altering the structure of the image in a predictable manner, as for example a concave elliptical insert centered on and aligned with an edge, which alteration is not visible to the eye. When decoding, area of concavity are determined, and a correlation is performed with a predicted insert function to assess whether code has been inserted. A hardware embodiment is described.

Abstract: The invention proceeds from a control of a transmission, which is continuously adjustable with respect to its transmission ratio, for a motor vehicle wherein the transmission together with a drive unit is mounted in the drive train of the motor vehicle. The drive unit has an adjustable output torque. According to the invention, determination means for determining a quantity is provided which represents the instantaneous maximum transmittable torque of the transmission. Furthermore, the output torque of the drive unit is limited to a limit value by limiting means. This limit value is determined in dependence upon the above-determined quantity. In order to reliably protect the transmission against damage by increased slippage, it is therefore provided according to the invention to limit the torque outputted by the engine when the contact force is so small that the danger of slippage exists. The torque of the motor can, in general, be more rapidly limited than the contact force can be increased.

Abstract: A drive train (10, 10a, 10b) for a motor vehicle is proposed, in which an interruption in the traction force transferred by an internal combustion engine (12) to a transmission (36) dictated by disengaging at least one clutch (16, 42) is bypassed. This purpose is served by a device (21, 21a, 21b), which has an electrical machine (22, 22a, 22b) that is connected to a power takeoff side, in particular an output shaft (36) of the transmission (38). Thus when the traction force is interrupted by a clutch (16, 42), a traction force is transferred, which increases driving safety and comfort.

Abstract: The invention proceeds from a control of the drive train of a motor vehicle having at least a drive unit and an automatic transmission. During driving operation, a desired value for the drive torque of the vehicle or for the transmission output torque is pregiven by the driver. The different operating points of the drive train are characterized by at least different output torques of the drive unit and rpm ratios and/or different output rpms of the drive unit. The essence of the invention is that, during driving operation, a set of evaluation quantities is determined for each possible operating point. One of the possible operating points is then selected as an optimal operating point via an optimization method based on the determined evaluation quantities. The transmission ratio, which belongs to this selected optimal operating point, is then adjusted on the transmission.

Abstract: A belt transmission having an adjustable transmission ratio and a drive end and an output end. The belt of the belt transmission establishes an operative mechanical connection where the slip can be influenced between the drive end and the output end, where an influencing device influences the slip of the belt means. At least two sensor units are provided and are arranged in the area of the belt and between the drive end and an output end. The signals of these sensor units are then sent to the influencing device to influence the slip of the belt. With the sensor units arranged in this manner, it is possible in a simple manner to detect the actual slip with a high accuracy and to use this to influence the slip.

Abstract: An apparatus for centering and gripping semiconductor wafers. A solenoid is used to actuate two or three curved contacts. Power to the solenoid, and position information from the solenoid is transmitted along a pair of wires. To center the wafer, the solenoid is actuated and the contacts move radially towards the center of the wafer. The contacts grip the edge of the wafer and a pulse-width-modulation signal is used to determine solenoid position as a function of back electromotive force value or waveform. During handling, the contacts hold the wafer such that the wafer does not move relative to the apparatus.

The output rpm of the vehicle engine is adjusted or controlled in dependence upon the detected rpm of the primary end in response to the determination of one such deceleration state. With the invention, it can be ensured that the vehicle with a CVT transmission comes to standstill for a transmission ratio close to the start transmission ratio even for especially intense decelerations at low speeds (30 to 60 km/hour).
